Bitcoin core RPC very slow: "mapOrphan overflow, removed 1 tx"

I am running bitcoin core v0.18.0 and noticed that now my queries made locally through the RPC are taking very long. Here is my bitcoin.conf:
txindex=1 datadir=/media/**** maxmempool=30000 mempoolexpiry=99999 choosedatadir=1 checkblocks=3 minrelayfee=0 maxconnections=9999 debug=mempool debug=mempoolrej addnode=*** addnode=*** logips=1 rest=1 rpcuser=*** rpcpassword=*** 
And here is a sample of the log, notice the unusual mapOrphan overflow lines:

The node is up-to-date and I didn't detect anything unusual (like a stale block/fork).

RiB Newsletter #14 – Are We Smart (Contract) Yet?

We’re seeing a bunch of interesting Rust blockchain and crypto projects, so this month the “Interesting Things” section is loaded up with news, papers, and project links.
This month, Elrond, appeared on our radar with the launch of their mainnet. Although not written in Rust, it runs Rust smart contracts on its Arwen WASM VM, which itself is based on the Rust Wasmer VM. Along with NEAR, Nervos, and Enigma (and probably others), this continues an encouraging trend of blockchains enabling smart contracts in Rust. See the “Interesting Things” section for examples of Elrond’s Rust contracts.
Rust continues to be popular for research into zero-knowledge proofs, with Microsoft releasing Spartan, a zk-SNARK system without trusted setup.
In RiB news, we published a late one-year anniversary blog post. It has some reflection on the changes to, and growth of, RiB over the last year.
The Awesome Blockchain Rust project, which is maintained by Sun under the rust-in-blockchain GitHub org, has received a stream of updates recently, and is now published as the Awesome-RiB page on rustinblockchain.org.
It’s a pretty good resource for finding blockchain-related Rust projects, with links to many of the more prominent and mature projects noted in the RiB newsletter. It could use more eyes on it though.

Project Spotlight

Each month we like to shine a light on a notable Rust blockchain project. This month that project is…
ethers.rs
ethers.rs is an Ethereum & Celo library and wallet implementation, implemented as a port of the ethers.js library to Rust.
Ethereum client programming is usually done in JavaScript with either web3.js or ethers.js, with ethers.js being the newer of the two. These clients communicate to an Ethereum node, typically via JSON-RPC (or, when in the browser, via an “injected” client provider that follows EIP-1193, like MetaMask).
ethers.rs then provides a strongly-typed alternative for writing software that interacts with the Ethereum network.
As of now it is only suited for non-browser use cases, but if you prefer hacking in Rust to JavaScript, as some of us surely do, it is worth looking into for your next Ethereum project.
The author of ethers.rs, Georgios Konstantopoulos, accepts donations to sponsor their work.
Note that there is also a Rust alternative to web3.js, rust-web3.

PYRK Tokens and future plans for their development

PYRK Tokens and future plans for their development
Hello. 👋🏻 In this post, we will tell you about PYRK Tokens and future plans for their development.
💡 Crypto coins halving is an event when the reward for mining new blocks is halved. When this happens, miners begin to receive 50% less for transaction processing. Usually, halving occurs approximately once every 200,000 blocks, for Bitcoin it is approximately every four years. It is planned to carry out halving until the maximum volume is reached.
❗️ The PYRK system uses quite a different approach to limiting mining inflation. So-called halving will occur every 200,000 units, and supply will be reduced by 20%.
❗️ Other cryptocurrencies usually implement a 50% halving. We, however, decided to reduce it to 20% to reduce the initial shock impact of a halving event.
✅ Total supply of PYRK coins becomes logarithmic due to the halving nature. And, thus, a maximum total supply will be approximately 100 Million Pyrk. According to our calculations, approximately 50% of the maximum supply will be mined in the first 3 years.
✅ The PYRK team also plans an improvement - Simple Tokens. The idea is something similar to the SLP (Simple Ledger Protocol) used by Bitcoin Cash and ERC Tokens used by Ethererum. Our protocol is easier to create and use than both.
✅ One of the issues with using the Bitcoin Cash system is that the functionality of Tokens are not built into the core client, therefore to use or integrate tokens requires additional programming libraries. Second, while the BCH chain is strong, is it also slow, with a block average of 10 minutes. This is fine for large transactions, but if you want to send transactions quickly this becomes an issue. The Pyrk blockchain has an average block time of 90 seconds. Last, the transaction fees on the BCH network will be higher in USD value than a similar transaction on the Pyrk blockchain.
✅ Ethereum ERC-20 tokens are also a popular choice, however these tokens require programming a contract using the Solidity language of Ethereum. If you don’t program your contract correctly, you could end up having big problems later on. Pyrk has taken out all the guess work in creating tokens and offers two of the most popular token types. Fungible tokens, which are tokens that are replaceable with each other and have equal value. These are the same as ERC-20. The other type is Non-Fungible tokens, in which each token is unique. Each of these token types has their own use case depending on the users needs.
✅ The Pyrk token system will be built into the core RPC functionality of the Pyrk software client. Anybody who has the Pyrk wallet can create, send, and receive tokens in seconds. This makes integration with exchanges easier as well.

Electroneum Fork 324500

Source: https://www.facebook.com/electroneum/posts/2030562537205714
Hi Everyone!
ALL ELECTRONEUM NODE OWNERS MUST UPDATE THEIR SOFTWARE BY BLOCK 324500 (approx. 36 hours from now – this is an URGENT UPDATE – PLEASE SHARE THIS INFORMATION)
We have an urgent software update below for anyone who runs a full Electroneum Node. If you don’t know what a node is , don’t worry! You won’t need to do anything.
We also have a VERY exciting update about an upcoming listing on a top 10 exchange.
How will I mine Electroneum after this update?
Instant Payment vendor API is open for BETA applicants.How can ETN change the world?
Please note that nothing in this message refers to MOBILE MINING – we are referring to the underlying blockchain miners.
Urgent Electroneum Node / RPC / Command Line Wallet Update
ALL ELECTRONEUM NODE OWNERS MUST UPDATE THEIR SOFTWARE BY BLOCK 324500 (approx. 36 hours from now – this is an URGENT UPDATE – PLEASE SHARE THIS INFORMATION)
https://github.com/electron…/electroneum/releases/…/v2.1.0.0
It’s only been a few short days since I made a video and said “our fork went well! We’re ready for 20m Users!”.
The fork was a great success, from a technical standpoint. Unfortunately, we never got back the number of GPU miners that are needed to ensure our network runs smoothly and has stable block emission. A new phenomenon has emerged where a number of users are mining Electroneum in waves. They come on and then leave after a few hours in a coordinated manner to mine ETN in a completely selfish way. We can’t blame people for maximizing their profit, but we have not built up the amount of “hashing power” that is required to make this impossible and create the stability we need in the network.
This has left us at risk. As such, we have to take urgent action to stabilise our network and protect the Electroneum community.
Coinbene Listing Electroneum & our network stability
We have formally agreed and signed contracts to be listed in July on the AWESOME, top 10, cryptocurrency exchange https://Coinbene.com & https://Coinbene.com.br
Coinbene have 1.5m active users and are a GREAT fit for Electroneum. Their primary markets are Latin America and Asia – which fits perfectly with Electroneum’s customer base. They have seen enormous growth over the last few months and have been very positive about the Electroneum Project.
Whilst this is great news, we will need much more hashing power to ensure we have network stability for our listing on this exchange, so we’ve taken the decision that we can’t wait any longer for GPU miners to return to us and we must run an urgent software update to re-introduce ASIC mining to Electroneum.
This is a very positive move for Electroneum. A great deal of Bitcoin’s trust and appeal is from the enormous hashing power and distribution of miners on the network. Bitcoin & LiteCoin have embraced ASICs and we feel that it is the right thing for Electroneum to do the same.
ASICS are becoming more prevalent, they cost considerably less to run than a GPU rig and use a fraction of the electricity. We are going to encourage more ASIC ownership and take our hashing rate up to (and beyond) the enormous levels of hashing power that we had before the May fork.
There is a further development. The first generation of hardware called an FPGA miner is arriving during 2018 and they make ANTI-ASIC capabilities a thing of the past, as they circumvent the slow delivery time of new ASICs by being re-programmable. If we are ready to embrace these rather than fight them, our network hashing power is increased further and our network stability and security is further enhanced.
Because ASICS run cooler, quieter and use a fraction of GPU rig power, they are suitable for MORE people to run in their homes. If you are interested, a search of “Cryptonight ASIC miner” in Google or Ebay will find the equipment needed to mine Electroneum. You will need to be reasonably technical to achieve this!
Having a stable network is absolutely key to both delivering mass adoption and to ensure we have a great relationship with the great exchanges that we’re already listed with, and to encourage more of the larger exchanges to see Electroneum as a coin that they want on board.
How will I mine Electroneum after this update?
If you are a mobile miner – nothing changes. If you are a GPU or ASIC miner then you’ll need to connect to an Electroneum pool but it is important to note that you will need to change your ALGORITHM. You MUST use the algorithm “Cryptonight” and NOT “Electroneum” or “CryptonightV7”. This will ensure your device works after the update. We will communicate this to all pools, but if you are a member of a mining pool – PLEASE LET THE ADMINS KNOW ABOUT THIS CRITICAL UPDATE. They must update their pool node by block 324500, which is only around 36 hours away.
Instant Payment vendor API is open for BETA applicants
Instant Cryptocurrency Payments via smart phone has always been a critical part of what Electroneum required to achieve mass market adoption. It’s never been done, but 9 short months after our ICO we are excited to announce that we have opened to the doors to vendors who would like to accept payment via Electroneum. The application is to be part of the BETA rollout of instant payment, but will operate on the live blockchain with real ETN!
If you run a business or know someone who does – why not recommend they apply to accept ETN. The Press and Marketing opportunities for the first, in any sector, to accept cryptocurrency are huge! Be part of the instant payment API BETA program by completing this form:
https://docs.google.com/…/1FAIpQLSfKTwWT7W4ltmApZO…/viewform
How can ETN change the world?
Instant payment does far more than allow people to pay for their coffee with crypto instead of their VISA card.
If you’d like to know more about Electroneum’s future I suggest you read a fantastic article that describes its coming role in the world, by fellow director Chris Gorman OBE (Officer of the British Empire – awarded by the Queen of England!): https://www.linkedin.com/…/how-cryptocurrency-enable-financ…
Electroneum has one of the largest of all cryptocurrency communities and it is made up of passionate and amazing people. With your support and world changing things we have coming out over the next few weeks, we can use this update to make our blockchain foundation secure and lead the world in mobile cryptocurrency.
I'm sure you agree that we've been through some challenging times which our team have always dealt with and learned from. The strength and support from our community and many of our goals becoming a reality combined with this blockchain update will give us the perfect foundation to deliver the Electroneum vision that we all share.
Thanks for taking the time to read this long message.
Have a great day everyone,
Richard Ells

Developer Update #4 21/01/18

Hey all,
As the main exchanges seem to be holding up I felt it would be a good to discuss a few things:
1) Syncing The current sync system for v9.0 is that when a node (node A) is syncing it connects to another node (node B) and asks for all the un-synced account's frontiers (in bitcoin speak - latest block of a blockchain, for RaiBlocks thats a chain for each account). The node then proceeds to download each account's blocks in turn. Some of the issues that users have faced include if the node B has poor connection and is slow or doesn't actually have the missing blocks, this can result in sync becoming stuck.
https://github.com/clemahieu/raiblocks/commit/2d4e12cb1cdcb2474ea4eec6854d8bdaf2edfdb2 now allows you to use the RPC 'bootstrap' command to add a fully synced node to bootstrap off, it now will kill the current connection and connect to this new node and download all the required blocks. This change actually came about from the work we were doing with the exchanges, here we were able to bootstrap off the other exchange's node which was already in-sync. More recently the dev team have been developing more efficient methods of syncing, for example (https://github.com/clemahieu/raiblocks/commit/1424334957c13549b87c17322c76d97309a4ce4f/), here the node downloads a range of blocks between two hashes - early tests (on a loopback system) resulted in syncing in the region of minutes rather then days... Easy initial syncing is obviously vital for adoption and so this will remain a key focus of the development team, this is just the beginning of improvements and optimisations.
2) 3rd Party Projects We've seen some awesome projects coming out of the community in the last few weeks, its great to see RaiBlocks being used in real world applications. We are already in contact with a number of these projects and we are happy to support any projects with technical advice if needed.
Summary
  1. The nodes I'm monitoring appear to be continuing to work well.
  2. We are working on optimising syncing.
  3. The community is awesome and is making very cool things.
  4. I'll post again tomorrow

Optimizing application with designer patter with cpp

Hello Guys

I have a question on optimizing my code, so I have a wrapper for an RPC 1.0 framework, and I utilizing two patterns for realizing the system of the command, so the Patter Mediator and the Patter Command,

The mediator has more commands, so with the command I pass the container to creating a Graph with the information of the command, and in the second moment I serializing the container concept (In java this concept container is an Object but in my project c++ no because I didn't use new)

My UML is this https://i.imgur.com/9b1yILg.png

My question is on the I how to build the code, with the C++ is correct approach? or this code could be slow down code execution?
I realizing this with this code

Interface command
#include  #include  #include  #include "../core/graph/WrapperInformations.h" namespace spyCBlockRPC { class IRPCCommand { public: virtual void doCommand(WrapperInformations &wrapper, BitcoinAPI &bitcoinApi) = 0; }; } 
The Mediator command
#include  #include  #include  #include "IRPCCommand.h" #include "DecodeScriptCommand.h" #include "DecodeRawTransaction.h" #include "DecodeBlockAtIndexCommand.h" #include "../ConfiguratorSingleton.h" //TODO add an personal exception namespace spyCBlockRPC { class RPCCommandMediator { public: const std::string DECODE_SCRIPT_COMMAND = "DECODE_SCRIPT_COMMAND"; inline static RPCCommandMediator& getInstance() { static RPCCommandMediator SINGLETON; return SINGLETON; } inline void doCommand(std::string keyCommand, WrapperInformations &wrapper) { if(keyCommand.empty()) { // create exception return; } if(keyCommand == DECODE_SCRIPT_COMMAND) { decodeScript.doCommand(wrapper, bitcoinApi); return; } if(keyCommand == DECODE_RAW_TX_COMMAND) { decodeRawTx.doCommand(wrapper, bitcoinApi); } if(keyCommand == DECODE_BLOCKS_COMMAND) { DecodeBlockAtIndexCommand decodeBlock; decodeBlock.doCommand(wrapper, bitcoinApi); } //Throws an exeption return; } private: //Commands DecodeScriptCommand decodeScript; DecodeRawTransaction decodeRawTx; //Bitcoin api BitcoinAPI bitcoinApi; }; } 
The transaction Wrapper, do the interface to creating a graph and it has a refinement to the mediator and calls the necessary command to build the graph
namespace spyCBlockRPC { class WrapperInformations { public: std::string getFrom() const; void setFrom(const std::string &value); std::string getTo() const; void setTo(const std::string &value); std::vector getLinkInformations() const; void setLinkInformations(const std::vector &value); void addInformationLink(const std::string &information); std::vector getFromIdWallets() const; std::vector getToIdWallets() const; void setToIdWallets(const std::vector &value); void setFromIdWallets(const std::vector &value); std::string getDelimitator() const; void setDelimitator(const std::string &value); std::string getHashPreviousTx() const; void setHashPreviousTx(const std::string &value); uint64_t getNOutpoint() const; void setNOutpoint(const uint64_t &value); int getHeightBlockchain() const; void setHeightBlockchain(int value); int getStartBlock() const; void setStartBlock(int value); private: std:: string hashPreviousTx; uint64_t nOutpoint; std::string from; std::vector fromIdWallets; std::string to; std::vector toIdWallets; std::vector linkInformations; std::string delimitator; int heightBlockchain = -1; int startBlock = 1; }; }

[META] New to PC Building? - September 2018 Edition

Intro

You've heard from all your gaming friends/family or co-workers that custom PCs are the way to go. Or maybe you've been fed up with your HP, Dell, Acer, Gateway, Lenovo, etc. pre-builts or Macs and want some more quality and value in your next PC purchase. Or maybe you haven't built a PC in a long time and want to get back into the game. Well, here's a good place to start.

Instructions

  1. Make a budget for your PC (e.g., $800, $1000, $1250, $1500, etc.).
  2. Decide what you will use your PC for.
    • For gaming, decide what games and at what resolution and FPS you want to play at.
    • For productivity, decide what software you'll need and find the recommended specs to use those apps.
    • For a bit of both, your PC build should be built on the HIGHEST specs recommended for your applications (e.g., if you only play FortNite and need CPU power for CFD simulations, use specs recommended for CFD).
    Here are some rough estimates for builds with entirely NEW parts:
    1080p 60FPS ultra-settings modern AAA gaming: ~$1,200
    1440p 60FPS high/ultra-settings modern AAA gaming: ~$1,600
    1080p 144FPS ultra-settings modern AAA gaming: $2,000
    4K 50FPS medium/high-settings modern AAA gaming: > $2,400
    It's noted that some compromises (e.g., lower settings and/or resolution) can be made to achieve the same or slightly lower gaming experience within ±15% of the above prices. It's also noted that you can still get higher FPS on older or used PCs by lowering settings and/or resolution AND/OR buying new/used parts to upgrade your system. Make a new topic about it if you're interested.
    Also note that AAA gaming is different from e-sport games like CSGO, DOTA2, FortNite, HOTS, LoL, Overwatch, R6S, etc. Those games have lower requirements and can make do with smaller budgets.
  3. Revise your budget AND/OR resolution and FPS until both are compatible. Compare this to the recommended requirements of the most demanding game on your list. For older games, you might be able to lower your budget. For others, you might have to increase your budget.
    It helps to watch gaming benchmarks on Youtube. A good example of what you're looking for is something like this (https://www.youtube.com/watch?v=9eLxSOoSdjY). Take note of the resolution, settings, FPS, and the specs in the video title/description; ask yourself if the better gaming experience is worth increasing your budget OR if you're okay with lower settings and lowering your budget. Note that you won't be able to see FPS higher than 60FPS for Youtube videos; something like this would have to be seen in-person at a computer shop.
  4. Make a build on https://ca.pcpartpicker.com/. If you still have no idea how to put together parts, start here (http://www.logicalincrements.com/) to get an understanding of PC part tiers. If you want more info about part explanations and brief buying tips, see the next section below.
  5. Click on the Reddit logo button next to Markup, copy and paste the generated text (in markup mode if using new Reddit), and share your build for review!
  6. Consider which retailer to buy your parts from. Here's a table comparing different retailers: https://docs.google.com/spreadsheets/d/1L8uijxuoJH4mjKCjwkJbCrKprCiU8CtM15mvOXxzV1s/edit?usp=sharing
  7. Buy your parts! Use PCPP above to send you e-mail alerts on price drops or subscribe to /bapcsalescanada for deals.
    You can get parts from the following PC retailers in alphabetical order:
  8. After procuring your parts, it's time to build. Use a good Youtube tutorial like this (https://www.youtube.com/watch?v=IhX0fOUYd8Q) that teach BAPC fundamentals, but always refer to your product manuals or other Youtube tutorials for part-specific instructions like CPU mounting, radiator mounting, CMOS resetting, etc. If it everything still seems overwhelming, you can always pay a computer shop or a friend/family member to build it for you.
    It might also be smart to look up some first-time building mistakes to avoid:

CPU

https://www.tomshardware.com/news/intel-9000-series-cpu-faq,37743.html
Intel 9000 CPUs (Coffee Lake Refresh) will be coming out in Q4. With the exception of i9 (8-core, 12 threads) flagship CPUs, the i3, i5, and i7 lineups are almost identical to their Intel 8000 (Coffee Lake) series, but slightly clocked faster. If you are wondering if you should upgrade to the newer CPU on the same tier (e.g., i5-8400 to i5-9400), I don't recommend that you do as you will only see marginal performance increases.

Mobo

https://www.anandtech.com/show/13135/more-details-on-intels-z390-chipset-exposed
Z370s will now be phased out for Z390s boards, which will natively support Intel 9000 CPUs (preferably i5-9600K, i7-9700K, and i9-9900K).

GPU

https://www.youtube.com/watch?v=WDrpsv0QIR0
RTX 2080 and 2080 Ti benchmarks are out; they provide ~10 and ~20 frames better than the 1080 Ti and also feature ray tracing (superior lighting and shadow effects) which is featured in only ~30 games so far (i.e., not supported a lot); effectively, they provide +25% more performance for +70% increased cost. My recommendation is NOT to buy them unless you need it for work or have lots of disposable income. GTX 1000 Pascal series are still relevant in today's gaming specs.

Part Explanations

CPU

The calculator part. More GHz is analogous to fast fingers number crunching in the calculator. More cores is analogous to having more calculators. More threads is analogous to having more filing clerks piling more work for the calculator to do. Microarchitectures (core design) is analogous to how the internal circuit inside the calculator is designed (e.g., AMD FX series are slower than Intel equivalents even with higher OC'd GHz speeds because the core design is subpar). All three are important in determining CPU speed.
In general, higher GHz is more important for gaming now whereas # cores and threads are more important for multitasking like streaming, video editing, and advanced scientific/engineering computations. Core designs from both AMD and Intel in their most recent products are very good now, but something to keep in mind.

Overclocking

The basic concept of overclocking (OCing) is to feed your CPU more power through voltage and hoping it does calculations faster. Whether your parts are good overclockers depends on the manufacturing process of your specific part and slight variations in materials and manufacturing process will result in different overclocking capability ("silicon lottery"). The downside to this is that you can void your warranties because doing this will produce excess heat that will decrease the lifespan of your parts AND that there is a trial-and-error process to finding OC settings that are stable. Unstable OC settings result in computer freezes or random shut-offs from excess heat. OCing will give you extra performance often for free or by investing in a CPU cooler to control your temperatures so that the excess heat will not decrease your parts' lifespans as much. If you don't know how to OC, don't do it.

Current Products

Intel CPUs have higher GHz than AMD CPUs, which make them better for gaming purposes. However, AMD Ryzen CPUs have more cores and threads than their Intel equivalents. The new parts are AMD Ryzen 3, 5, or 7 2000 series or Intel i3, i5, or i7 8000 series (Coffee Lake). Everything else is outdated.
If you want to overclock on an AMD system, know that you can get some moderate OC on a B350/B450 with all CPUs. X370/X470 mobos usually come with better VRMs meant for OCing 2600X, 2700, and 2700X. If you don't know how to OC, know that the -X AMD CPUs have the ability to OC themselves automatically without manually settings. For Intel systems, you cannot OC unless the CPU is an unlocked -K chip (e.g., i3-8350K, i5-8600K, i7-8700K, etc.) AND the motherboard is a Z370 mobo. In general, it is not worth getting a Z370 mobo UNLESS you are getting an i5-8600K and i7-8700K.

CPU and Mobo Compatibility

Note about Ryzen 2000 CPUs on B350 mobos: yes, you CAN pair them up since they use the same socket. You might get an error message on PCPP that says that they might not be compatible. Call the retailer and ask if the mobo you're planning on buying has a "Ryzen 2000 Series Ready" sticker on the box. This SHOULD NOT be a problem with any mobos manufactured after February 2018.
Note about Intel 9000 CPUs on B360 / Z370 mobos: same as above with Ryzen 2000 CPUs on B350 or X370 boards.

CPU Cooler (Air / Liquid)

Air or liquid cooling for your CPU. This is mostly optional unless heavy OCing on AMD Ryzen CPUs and/or on Intel -K and i7-8700 CPUs.
For more information about air and liquid cooling comparisons, see here:

Motherboard/mobo

Part that lets all the parts talk to each other. Comes in different sizes from small to big: mITX, mATX, ATX, and eATX. For most people, mATX is cost-effective and does the job perfectly. If you need more features like extra USB slots, go for an ATX. mITX is for those who want a really small form factor and are willing to pay a premium for it. eATX mobos are like ATX mobos except that they have more features and are bigger - meant for super PC enthusiasts who need the features.
If you are NOT OCing, pick whatever is cheap and meets your specs. I recommend ASUS or MSI because they have RMA centres in Canada in case it breaks whereas other parts are outside of Canada like in the US. If you are OCing, then you need to look at the quality of the VRMs because those will greatly influence the stability and lifespan of your parts.

Memory/RAM

Part that keeps Windows and your software active. Currently runs on the DDR4 platform for new builds. Go for dual channel whenever possible. Here's a breakdown of how much RAM you need:
AMD Ryzen CPUs get extra FPS for faster RAM speeds (ideally 3200MHz) in gaming when paired with powerful video cards like the GTX 1070. Intel Coffee Lake CPUs use up a max of 2667MHz for B360 mobos. Higher end Z370 mobos can support 4000 - 4333MHz RAM depending on the mobo, so make sure you shop carefully!
It's noted that RAM prices are highly inflated because of the smartphone industry and possibly artificial supply shortages. For more information: https://www.extremetech.com/computing/263031-ram-prices-roof-stuck-way

Storage

Part that store your files in the form of SSDs and HDDs.

Solid State Drives (SSDs)

SSDs are incredibly quick, but are expensive per TB; they are good for booting up Windows and for reducing loading times for gaming. For an old OEM pre-built, upgrading the PC with an SSD is the single greatest speed booster you can do to your system. For most people, you want to make sure the SSD you get is NOT DRAM-less as these SSDs do not last as long as their DRAM counterparts (https://www.youtube.com/watch?v=ybIXsrLCgdM). It is also noted that the bigger the capacity of the SSD, the faster they are. SSDs come in four forms:
The 2.5" SATA form is cheaper, but it is the old format with speeds up to 550MB/s. M.2 SATA SSDs have the same transfer speeds as 2.5" SATA SSDs since they use the SATA interface, but connect directly to the mobo without a cable. It's better for cable management to get an M.2 SATA SSD over a 2.5" SATA III SSD. M.2 PCI-e SSDs are the newest SSD format and transfer up to 4GB/s depending on the PCI-e lanes they use (e.g., 1x, 2x, 4x, etc.). They're great for moving large files (e.g., 4K video production). For more info about U.2 drives, see this post (https://www.reddit.com/bapccanada/comments/8jxfqs/meta_new_to_pc_building_may_2018_edition/dzqj5ks/). Currently more common for enterprise builds, but could see some usage in consumer builds.

Hard Disk Drives (HDDs)

HDDs are slow with transfer speeds of ~100MB/s, but are cheap per TB compared to SSDs. We are now at SATA III speeds, which have a max theoretical transfer rate of 600MB/s. They also come in 5400RPM and 7200RPM forms. 5400RPM uses slightly less power and are cheaper, but aren't as fast at dealing with a large number of small files as 7200RPM HDDs. When dealing with a small number of large files, they have roughly equivalent performance. It is noted that even a 10,000RPM HDD will still be slower than an average 2.5" SATA III SSD.

Others

SSHDs are hybrids of SSDs and HDDs. Although they seem like a good combination, it's much better in all cases to get a dedicated SSD and a dedicated HDD instead. This is because the $/speed better for SSDs and the $/TB is better for HDDs. The same can be said for Intel Optane. They both have their uses, but for most users, aren't worth it.

Overall

I recommend a 2.5" or M.2 SATA ≥ 250GB DRAM SSD and a 1TB or 2TB 7200RPM HDD configuration for most users for a balance of speed and storage capacity.

Video Card/GPU

Part that runs complex calculations in games and outputs to your monitor and is usually the most expensive part of the budget. The GPU you pick is dictated by the gaming resolution and FPS you want to play at.
In general, all video cards of the same product name have almost the same non-OC'd performance (e.g., Asus Dual-GTX1060-06G has the same performance as the EVGA 06G-P4-6163-KR SC GAMING). The different sizes and # fans DO affect GPU OCing capability, however. The most important thing here is to get an open-air video card, NOT a blower video card (https://www.youtube.com/watch?v=0domMRFG1Rw). The blower card is meant for upgrading pre-builts where case airflow is limited.
For cost-performance, go for the NVIDIA GTX cards because of the cryptomining industry that has inflated AMD RX cards. Bitcoin has taken a -20% hit since January's $10,000+ as of recently, but the cryptomining industry is still ongoing. Luckily, this means prices have nearly corrected itself to original MSRP in 2016.
In general:
Note that if your monitor has FreeSync technology, get an AMD card. If your monitor has G-Sync, get a NVIDIA card. Both technologies allow for smooth FPS gameplay. If you don't have either, it doesn't really matter which brand you get.
For AMD RX cards, visit https://www.pcworld.com/article/3197885/components-graphics/every-amd-radeon-rx-graphics-card-you-can-buy-for-pc-gaming.html

New NVIDIA GeForce RTX Series

New NVIDIA 2000 RTX series have been recently announced and will be carried in stores in Q3 and Q4. Until all of the products have been fully vetted and reviewed, we cannot recommend those yet as I cannot say if they are worth what NVIDIA has marketed them as. But they will be faster than their previous equivalents and will require more wattage to use. The 2070, 2080, and 2080 Ti will feature ray tracing, which is a new feature seen in modern CG movies that greatly enhances lighting and shadow effects. At this time, < 30 games will use ray tracing (https://www.pcgamer.com/21-games-will-support-nvidias-real-time-ray-tracing-here-are-demos-of-tomb-raider-and-control/). It's also noted that the 2080 Ti is the Titan XP equivalent, which is why it's so expensive. (https://www.youtube.com/watch?v=Irs8jyEmmPQ) The community's general recommendation is NOT to pre-order them until we see some reviews and benchmarks from reviewers first.
Looks like a couple of benchmarks are out. While keeping other parts equal the following results were obtained(https://videocardz.com/77983/nvidia-geforce-rtx-2080-ti-and-rtx-2080-official-performance-unveiled). So the 2080 and 2080 Ti are better than last generation's 1080 Ti by ~10 and ~20 frames respectively.

Case

Part that houses your parts and protects them from its environment. Should often be the last part you choose because the selection is big enough to be compatible with any build you choose as long as the case is equal to or bigger than the mobo form factor.
Things to consider: aesthetics, case airflow, cable management, material, cooling options (radiators or # of fan spaces), # fans included, # drive bays, toolless installation, power supply shroud, GPU clearance length, window if applicable (e.g., acrylic, tempered glass), etc.
It is recommended to watch or read case reviews on Youtube to get an idea of a case's performance in your setup.

Power Supply/PSU

Part that runs your PC from the wall socket. Never go with an non-reputable/cheap brand out on these parts as low-quality parts could damage your other parts. Recommended branded PSUs are Corsair, EVGA, Seasonic, and Thermaltake, generally. For a tier list, see here (https://linustechtips.com/main/topic/631048-psu-tier-list-updated/).

Wattage

Wattage depends on the video card chosen, if you plan to OC, and/or if you plan to upgrade to a more powerful PSU in the future. Here's a rule of thumb for non-OC wattages that meet NVIDIA's recommendations:
There are also PSU wattage calculators that you can use to estimate your wattage. How much wattage you used is based on your PC parts, how much OCing you're doing, your peripherals (e.g., gaming mouse and keyboard), and how long you plan to leave your computer running, etc. It is noted that these calculators use conservative estimates, so use the outputted wattage as a baseline of how much you need. Here are the calculators (thanks, VitaminDeity).
Pick ONE calculator to use and use the recommended wattage, NOT recommended product, as a baseline of what wattage you need for your build. Note that Cooler Master and Seasonic use the exact calculator as Outervision. For more details about wattage, here are some reference videos:

Modularity

You might also see some info about modularity (non-modular, semi-modular, or fully-modular). These describe if the cables will come connected to the PSU or can be separated of your own choosing. Non-modular PSUs have ALL of the cable connections attached to the PSU with no option to remove unneeded cables. Semi-modular PSUs have separate cables for HDDs/SSDs and PCI-e connectors, but will have CPU and mobo cables attached. Modular PSUs have all of their cables separate from each other, allowing you to fully control over cable management. It is noted that with decent cooling and airflow in your case, cable management has little effect on your temperatures (https://www.youtube.com/watch?v=YDCMMf-_ASE).

80+ Efficiency Ratings

As for ratings (80+, 80+ bronze, 80+ gold, 80+ platinum), these are the efficiencies of your PSU. Please see here for more information. If you look purely on electricity costs, the 80+ gold PSUs will be more expensive than 80+ bronze PSUs for the average Canadian user until a breakeven point of 6 years (assuming 8 hours/day usage), but often the better performance, longer warranty periods, durable build quality, and extra features like fanless cooling is worth the extra premium. In general, the rule of thumb is 80+ bronze for entry-level office PCs and 80+ gold for mid-tier or higher gaming/workstation builds. If the price difference between a 80+ bronze PSU and 80+ gold PSU is < 20%, get the 80+ gold PSU!

Warranties

Warranties should also be looked at when shopping for PSUs. In general, longer warranties also have better PSU build quality. In general, for 80+ bronze and gold PSU units from reputable brands:
Any discrepancies are based on varied wattages (i.e., higher wattages have longer warranties) or updated warranty periods. Please refer to the specific product's warranty page for the correct information. For EVGA PSUs, see here (https://www.evga.com/support/warranty/power-supplies/). For Seasonic PSUs, see here (https://seasonic.com/support#period). For Corsair PSUs, see here (https://www.corsair.com/ca/en/warranty).
For all other PSU inquiries, look up the following review sites for the PSUs you're interested in buying:
These guys are engineering experts who take apart PSUs, analyze the quality of each product, and provide an evaluation of the product. Another great website is http://www.orionpsudb.com/, which shows which PSUs are manufactured by different OEMs.

Operating System (OS)

Windows 10

The most common OS. You can download the ISO here (https://www.microsoft.com/en-ca/software-download/windows10). For instructions on how to install the ISO from a USB drive, see here (https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/install-windows-from-a-usb-flash-drive) or watch a video here (https://www.youtube.com/watch?v=gLfnuE1unS8). For most users, go with the 64-bit version.
If you purchase a Windows 10 retail key (i.e., you buy it from a retailer or from Microsoft directly), keep in mind that you are able to transfer it between builds. So if you're building another PC for the 2nd, 3rd, etc. time, you can reuse the key for those builds PROVIDED that you deactivate your key before installing it on your new PC. These keys are ~$120.
However, if you have an OEM key (e.g., pre-builts), that key is tied specifically to your mobo. If you ever decide to upgrade your mobo on that pre-built PC, you might have to buy a new Windows 10 license. For more information, see this post (https://www.techadvisor.co.uk/feature/windows/windows-10-oem-or-retail-3665849/). The cheaper Windows 10 keys you can find on Kinguin are OEM keys; activating and deactivating these keys may require phoning an automated Microsoft activation line. Most of these keys are legitimate and cost ~$35, although Microsoft does not intend for home users to obtain this version of it. Buyer beware.
The last type of key is a volume licensing key. They are licensed in large volumes to corporate or commercial usage. You can find lots of these keys on eBay for ~$10, but if the IT department who manages these keys audit who is using these keys or if the number of activations have exceeded the number allotted on that one key, Microsoft could block that key and invalidate your license. Buyer beware.
For more information on differentiating between all three types of keys, see this page (https://www.tenforums.com/tutorials/49586-determine-if-windows-license-type-oem-retail-volume.html).
If money is tight, you can get Windows 10 from Microsoft and use a trial version of it indefinitely. However, there will be a watermark in the bottom-right of your screen until you activate your Windows key.

MacOS

If you're interested in using MacOS, look into Hackintosh builds. This will allow you to run MacOS to run on PC parts, saving you lots of money. These builds are pretty picky about part compatibility, so you might run into some headaches trying to go through with this. For more information, see the following links:

Linux

If you're interested in a free open-source OS, see the following links:
For more information, go to /linux, /linuxquestions, and /linux4noobs.

Peripherals

Monitors

Keyboards and Mice

Overall

Please note that the cost-performance builds will change daily because PC part prices change often! Some builds will have excellent cost-performance one day and then have terrible cost-performance the next. If you want to optimize cost-performance, it is your responsibility to do this if you go down this route!
Also, DO NOT PM me with PC build requests! It is in your best interests to make your own topic so you can get multiple suggestions and input from the community rather than just my own. Thanks again.

Sample Builds

Here are some sample builds that are reliable, but may not be cost-optimized builds. These builds were created on September 9, 2018; feel free to "edit this part list" and create your own builds.

Why today's stress test is nothing more than SV marketing

The previous stress test highlighted problems BCH has with blocks over ~22mb.
Some of those include:
  1. AcceptToMempool -- limiting how many transactions a node can process on current hardware
  2. DOS prevention -- limiting the transactions a networked node is willing to receive
  3. HTTP RPC protocol -- slow speed to transfer data between full nodes and pool software
1 & 2 are bottlenecks on the maximum throughput of the network.
3 slows down block propagation and increases risk of a larger block being orphaned
However, none of these real world issues will be tested on the SV chain today.
Instead of miners receiving transactions from other nodes on the network, all of the transactions will be generated on or near mining nodes.
Instead of being concerned about blocks being orphaned, all of the hashrate is owned by one entity.
Essentially scaling in SV cannot be observed or proven because the stress test environment will be more similar to Bitcoin Unlimited's Gigablock Testnet. 128mb blocks should be easy to recreate in such an environment as it's already a solved problem.

Configuring bitcoin full node for faster RPC calls

I have been working with a bitcoin full node and attempting to parse the blockchain data, whilst storing it in an external database.
The script I am using iterates through each block using getblock[hash;2] which populates multiple tables. However in order to get the current blocks input values we have to perform an expensive getRawTransaction each previous txid.
We have singled this out as the bottleneck in the code for most time taken, rendering the script very slow. We have also tried using RPC batching but this also takes considerable amount of time, potentially more with a memory overhead.
I am wondering if there is a best configuration of the daemon to improve RPC call speed? i.e. using rpcthread/queue, increasing dbcache etc.
Another option would be to implement blocks only mode, by reducing the bandwidth could this improve RPC commands?

Soo after almost 3 months of setting up I have my own LN full node running on RP3

Soo after almost 3 months of setting up I have my own LN full node running on RP3
I have been eager to try LN mainnet since the very beginning of it. I've found out about lnd, eclair, zap and other wallets but every scenario I tried to use it failed because of critical issues:
  • eclair does not really constitute a wallet, it's more like a credit card - you can send money but not receive it
  • lnd is okay, but requires a server and tons of resources for maintaining a full node, can't be used securely, efficiently and mobily at the same time
  • zap offers some cloud wallet (in testnet!) by default, this is a serious misunderstanding of my cryptoanarchy needs
  • web wallets - ah, forget it
So I've decided to use my Raspberry Pi with a very old laptop HDD attached (200GB so the pruning function has to be used) to create a backend wallet service and zap desktop (temporarily!) as my frontend control panel.
https://preview.redd.it/0vcq147887q11.png?width=1024&format=png&auto=webp&s=7bb6eccdd4110a857e5af0400acc2d7e1ee7ee85
Setting up Pi is easy, lots of tutorials over the internet, not gonna discuss it here. Then I had to obtain bitcoind (current rel: bitcoin-0.17.0-arm-linux-gnueabihf.tar.gz) and lnd (lnd-linux-armv7-v0.5-beta.tar.gz), create a bitcoin technical user, deploy the tools, configure and install new systemd services and go through the configs. This is a tricky part, so let's share:
# Generated by https://jlopp.github.io/bitcoin-core-config-generato # This config should be placed in following path: # ~/.bitcoin/bitcoin.conf # [core] # Set database cache size in megabytes; machines sync faster with a larger cache. Recommend setting as high as possible based upon machine's available RAM. dbcache=100 # Keep at most  unconnectable transactions in memory. maxorphantx=10 # Keep the transaction memory pool below  megabytes. maxmempool=50 # Reduce storage requirements by only storing most recent N MiB of block. This mode is incompatible with -txindex and -rescan. WARNING: Reverting this setting requires re-downloading the entire blockchain. (default: 0 = disable pruning blocks, 1 = allow manual pruning via RPC, greater than 550 = automatically prune blocks to stay under target size in MiB). prune=153600 # [network] # Maintain at most N connections to peers. maxconnections=40 # Use UPnP to map the listening port. upnp=1 # Tries to keep outbound traffic under the given target (in MiB per 24h), 0 = no limit. maxuploadtarget=5000 # [debug] # Log IP Addresses in debug output. logips=1 # [rpc] # Accept public REST requests. rest=1 # [wallet] # Do not load the wallet and disable wallet RPC calls. disablewallet=1 # [zeromq] # Enable publishing of raw block hex to 
. zmqpubrawblock=tcp://127.0.0.1:28332 # Enable publishing of raw transaction hex to
. zmqpubrawtx=tcp://127.0.0.1:28333 # [rpc] # Accept command line and JSON-RPC commands. server=1 # Username and hashed password for JSON-RPC connections. The field comes in the format: :$. RPC clients connect using rpcuser=/rpcpassword= arguments. You can generate this value with the ./share/rpcauth/rpcauth.py script in the Bitcoin Core repository. This option can be specified multiple times. rpcauth=xxx:yyy$zzz
Whooaa, this online config generator is really helpful, but I still had to manually correct a few things. The last line is obviously generated by rpcauth.py, I disabled the wallet functionality as lnd is going to take care of my funds. ZMQ is not available to the network so only my LND can use it, RPC usage I still have to think through a little, in general I would like to have my own block explorer some day but also be safe from any hacking attempts (thus I would need at least 2 RPC ports/user accounts - one for lnd, one for block explorer frontend). No ports open on firewall at this time, only UPnP is active and gently opens 8333 for block/tx transfers.
Now, synchronizing the blockchain took me time from mid-July to early September... The hard drive is really slow, also my external HDD drive has some trouble with its A/C adapter so Pi was getting undervoltage alerts all the time. Luckily, it is just downclocking when it happens and slowly but steadily synchronized the whole history. After all, I'm not paying even $5 monthly for a VPS, it is by design the cheapest hardware I could use to set up my LN wallet.
When bitcoind was ready (I've heard some stories about btcd but I don't trust this software yet, sorry), it's time to configure lnd.conf:
[Application Options] debuglevel=trace rpclisten=0.0.0.0:10009 externalip=X.X.X.X:9735 listen=0.0.0.0:9735 alias=X color=#XXXXXX [Bitcoin] bitcoin.active=1 bitcoin.mainnet=1 bitcoin.node=bitcoind [Bitcoind] bitcoind.rpchost=127.0.0.1 bitcoind.rpcuser=X bitcoind.rpcpass=X bitcoind.zmqpubrawblock=tcp://127.0.0.1:28332 bitcoind.zmqpubrawtx=tcp://127.0.0.1:28333 
Here I've had to XXX a little more fields, as not only the bitcoind RPC credentials are stored here, but also my node's public information (it should be illegal to run nodes without specifically selected color and alias!). It is public (and I had to open port 9735 on my firewall), but not necessarily connected to my reddit account for most of the adversaries, so let's keep it this way. In fact, I also see a security vulnerability here: my whole node's stability depends on the IP being static. I could swap it for a .tk domain but who can tell if the bad guys won't actively fight DNS system in order to prevent global economic revolution? As such, I would rather see node identification in LN based on a public key only with possible *hints* of last-known-ip-address but the whole discovery should be performed by the nodes themself in a p2p manner, obviously preventing malicious actors from poisoning the network in some way. For now, I consider the IP stability a weak link and will probably have to pay extra Bitcoin TX fees when something happens to it (not much of a cost luckily!).

https://preview.redd.it/hjd1nooo77q11.png?width=741&format=png&auto=webp&s=14214fc36e3edf139faade930f4069fc31a3e883
Okay then, lnd is up and running, had to create a wallet and give it a night for getting up to speed. I don't know really what took it so long, I'm not using Windows nor 'localhost' in the config so the issues like #1027 are not the case. But there are others like #1545 still open so I'm not going to ponder much on this. I haven't really got any idea how to automatically unlock the wallet after Pi restart (could happen any time!), especially since I only tried to unlock it locally with lncli (why would I enter the password anywhere outside that host?), but let's say that my wallet will only be as stable as my cheap hardware. That's okay for the beta phase.
Finally, zap-desktop required me to copy tls.cert and admin.macaroon files to my desktop. If my understanding of macaroon (it's like an authentication cookie, that can later be revoked) is correct then it's not an issue, however it would be nice to have a "$50 daily limit" macaroon file in the future too, just to avoid any big issues when my client machine gets stolen. Thanks to this, I can ignore the silly cloud-based modes and have fully-secure environment of my home network being the only link from me to my money.

Aaand there it is. The IP took some time to advertise, I use 1ml.com to see if my node is there. The zap interface (ZapDesktop-linux-amd64-v0.2.2-beta.deb) lacks lots of useful information so I keep learning lncli syntax to get more data about my new peers or the routes offered. The transactions indeed run fast and are ridiculously cheap. I would really love to run Eclair with the same settings but it doesn't seem to support custom lnd (why?). In fact, since all I need is really a lncli wrapper, maybe it will be easy to write my own (seen some web gui which weighs 700MB after downloading all dependencies with npm - SICK!). Zap for iOS alpha test registration is DOWN so I couldn't try it (and I'm not sure if it allows custom lnd selection), Zap for Android doesn't even exist yet... I made a few demo transactions and now I will explore all those fancy t-shirt stores as long as the prices are still in "early investor" mode - I remember times when one could get 0.001 BTC from a faucet...

If you find any of the facts presented by me false, I am happy to find out more in the discussion. However what I did I did mostly for fun, without paying much attention to the source code, documentation and endless issue lists on github. By no means I claim this tutorial will work for you but I do think I shared the key points and effort estimations to help others decide if they want a full-node LN client too. I'm also interested in some ideas on what to do with it next (rather unlikely that I will share my lnd admin.macaroon with anyone!) especially if it gives me free money. For example, I can open 1000 channels and start earning money from fees, although I no longer have more Bitcoins than the LN capacity yields... I will probably keep updating the software on my Pi until it leaves beta phases and only then will pour more money inside. I'm also keen on improving the general security of my rig and those comments I will answer more seriously.

    1. "Not a huge @rogerkver fan and never really used $BCH. But he wiped up the floor with @ToneVays in Malta, and even if you happen to despise BCH, it’s foolish and shortsighted not to take these criticisms seriously. $BTC is very expensive and very slow." (261 points, 131 comments)
    2. Jonathan Toomim: "At 32 MB, we can handle something like 30% of Venezuela's population using BCH 2x per day.

    3. Yes, Bitcoin was always supposed to be gold 2.0: digital gold that you could use like cash, so you could spend it anywhere without needing banks and gold notes to make it useful. So why is Core trying to turn it back into gold 1.0? (112 points, 85 comments)

    1. Erik Voorhees on Twitter: “I wonder if you realize that if Bitcoin didn’t work well as a payment system in the early days it likely would not have taken off.

    1. I believe the BCH denomination is the best (in contrast to bits, cash and sats), if used with eight digits & spaces: 0.001 234 00 BCH. This way both the BCH and the satoshi amount is immediately clear. Once the value of a satoshi gets close to 1¢, the dot can simply be dropped. (112 points, 41 comments)

  12. 322 points, 6 submissions: unitedstatian
    1. BCH is victim to one of the biggest manipulation campaigns in social media: Any mention of BCH triggered users instantly to spam "BCASH".. until BSV which is a BCH fork and almost identical to it pre-November fork popped out of nowhere and suddenly social media is spammed with pro-BSV posts. (131 points, 138 comments)

Ravencoin Open Developer Meeting - 2/15/2019

Hello everybody!

theking - Last Friday at 2:02 PM

Seems likes it’s been so long since this meeting was held. At least a month 📷

Tron - Last Friday at 2:02 PM

Hey

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:05 PM

BTW, blondfrogs won't be able to join us today. 📷

corby - Last Friday at 2:05 PM

Hi all

Chatturga - Last Friday at 2:05 PM

Blondefrogs has been working on the 2.2.2 update. He isnt here today, but he left this tidbit for the meeting:(edited)"Release 2.2.2 has a bunch of new updates. The sync speed fix that was released in 2.2.1 has been updated even more to use less memory/ram and uses less CPU. Each node used to hold all addresses that contained an asset as well as the amount in those addresses. That is now optional with the -assetindex flag. Which can be put into the raven.conf or added as a parameter when starting the wallet. Some other wallet issues were also fixed with this memory update. This is considered an mandatory update, especially if you haven't updated to 2.2.1 which resolved a potential fork bug fix. I would still suggest updating to 2.2.2 even if you are on 2.2.1."📷6

Jeroz - Last Friday at 2:07 PM

A bunch of testing has been happening and is currently running on the seed-nodes.

Tron - Last Friday at 2:10 PM

No timeline for dividends, but it is the one function that doesn't need any changes to consensus. And it can be done on tier 2 with a python script. The plan is still to build in a rpc call.📷2

truedev - Last Friday at 2:11 PM

alright

SpyderDev - Last Friday at 2:12 PM

We have been focusing on sync performance and have been running many tests. I've added an image of the results of this testing. Currently we still want to work on getting the Windows QT sync times faster (at least closer to what they are using just ravend). Overall we are very happy with the speeds and hope it will help people that have struggled getting their nodes up to date.(edited)📷

Jeroz - Last Friday at 2:13 PM

Yeah that table completely puzzled me

[Master] Roshii - Last Friday at 2:13 PM

hello!📷6

Jeroz - Last Friday at 2:13 PM

Fast branch is 2.2.1? or 2.2.2? Develop branch is 2.2.0?

SpyderDev - Last Friday at 2:15 PM

Sorry, should have clarified that. I was testing while it was still under development. On the table the top is the new-sync code, the bottom is the old "assets" release. As of about 5 minutes ago all of this code is on the develop branch.

Jeroz - Last Friday at 2:15 PM

Although syncing is mostly bottlenecked by cpu speed, that 16 core windows-qt still looks off to me. I synced windows Qt using 2.2.2 in ~2h on a i5-7600K.ok

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:17 PM

Okay, we good to move to the Mobile update?

SpyderDev - Last Friday at 2:17 PM

The Windows box is an AWS instance and there is some concern that the remote desktop could be slowing the QT UI down causing the horrible sync times. I am working on getting a local Windows 10 resource and will have updated information once that is ready (early next week).

Jeroz - Last Friday at 2:18 PM

ah that might explain. Ubuntu qt was 45 mins for me

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:18 PM

Jeroz - Last Friday at 2:20 PM

is android an easy port?

SpyderDev - Last Friday at 2:20 PM

Just copy and paste right Roshii 📷

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:20 PM

LOLNo, usually its a completely new development effort.For the RVN Wallets they are both written in native iOS/Android code.

[Master] Roshii - Last Friday at 2:21 PM

So the iOS and Android use the same Core SPV module written in C, and it's the most difficult part.I have already did some work when it comes to Android, and it's 70% finishedHave also to port all the changes we lately did to the iOS wallet ...

boatsandhoes - Last Friday at 2:21 PM

yeah, unfortunately its not as easy as cut and paste for ios to android

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:21 PM

I have an idea.(edited)📷7📷6

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:34 PM

That several other devs have helped with. 📷

Tron - Last Friday at 2:34 PM

📷

SpyderDev - Last Friday at 2:34 PM

and lawyers

Tron - Last Friday at 2:34 PM

When the project started, ICOs were the big thing. Now it is STOsThe main difference is the legal wrapping and rules around securities.If Ravencoin has two more token types (Tags and Restricted Assets), there are lots of ways to make compliant tokens.Importantly, it doesn't affect the existing tokens at all.Tags - Tokens that can be sent only by the issuer once (with metadata).These tokens start with (hashtag)(edited)📷8

SpyderDev - Last Friday at 2:37 PM

^(octothorpe)

Tron - Last Friday at 2:37 PM

The Restricted Assets start with $, and can be frozen by the issuer. But they only move between tagged addresses.(edited)

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:38 PM

Tags can be sent to a user's address after the issuer has done the necessary due diligence for an STO issuance.(edited)

Tron - Last Friday at 2:38 PM

The issuer determines which tags the Restricted Asset will honor.This can be used for lots of different use cases.

EEE - Last Friday at 2:38 PM

Stunning interface guys

boatsandhoes - Last Friday at 2:39 PM

will that determination be a setting in the wallet?

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:39 PM

Restricted assets can then only be sent to addresses that are allowed and have the proper Tags.

boatsandhoes - Last Friday at 2:39 PM

interesting📷1

J. | ravenland.org - Last Friday at 2:39 PM

Did you guys get contacted by some entity* whos forcing the restricted address policy? or is this done as precautionary measure? At first glance your idea sounds good Tron.(edited)

Tron - Last Friday at 2:39 PM

Example: $UBER token only moves among addresses tagged with #KYC

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:40 PM

So Ravenland will have to buy a bunch more spam tokens.📷4

SpyderDev - Last Friday at 2:40 PM

#ravenland.

boatsandhoes - Last Friday at 2:40 PM

so is the $ something that can be added to an existing asset?

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:40 PM

It's not a forced thing. But adding the ability for Raven to be used in new use cases where legal requirements exist.

Tron - Last Friday at 2:40 PM

Not contacted by anyone, and not precautionary. Ravencoin Assets are just tools. This is just another tool that will help issuers of security tokens.📷9📷4

BW__ - Last Friday at 2:41 PM

Love it.

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:41 PM

It'll be a new token type that you can create @boatsandhoes📷1

ravencoin maximalist 🧘🏻♂ - Last Friday at 2:41 PM

That sounds awesome

SpyderDev - Last Friday at 2:41 PM

I for one am very excited about this...📷4

Hans_Schmidt - Last Friday at 2:41 PM

How does the $ token owner specify the required # tags?

DeejayQQ - Last Friday at 2:41 PM

Can the same name have different token type?Sorry need time to digest

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:42 PM

Still working out the details. Tron will be posting additional info about the idea soon.

Steelers - Last Friday at 2:42 PM

Cool

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:42 PM

Feedback is wanted!

Tron - Last Friday at 2:42 PM

Q: Was this originally the plan for Ravencoin? A: No. This is in response to the regulatory ramp up in 2018 in some jurisdictions which requires that only known individuals or entities to operate peer-to-peer on certain tokens. For jurisdictions that allow unrestricted peer-to-peer transfer, we strongly encourage use of the original Ravencoin assets. The Restricted Assets are an adaptation to satisfy burdensome, privacy-destroying regulations, with a goal of reducing information replication which makes Ravencoin Restricted Assets a better alternative to those being promoted now.

jaysonb - Last Friday at 2:43 PM

all nodes will validate the transactions not just those interested in the transaction - i assume all will validate..

boatsandhoes - Last Friday at 2:43 PM

so essentially any name already secured in the hopes of having that functionality are worth less because they wont be able to?

theking - Last Friday at 2:44 PM

Can the restricted assets be time based in any way? For instance, in some STO regulated environment, there is a lockup for some period of time after issuance, but then after a certain period of time the restriction goes away and the securities can be traded. Is that contemplated at all?

DeejayQQ - Last Friday at 2:44 PM

If I already have Tron as my asset, there could be another Tron but under a different token type such as restricted assets?

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:44 PM

Yes all nodes will do consensus checks.

corby - Last Friday at 2:44 PM

@boatsandhoes there's going to be a grace period where you can purchase $XXX if you own XXXon the order of months

boatsandhoes - Last Friday at 2:45 PM

📷 📷 📷 📷

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:45 PM

Yes, you have the TRON asset and you can also have the $TRON asset.(edited)

Tron - Last Friday at 2:45 PM

Regarding the lockup....

boatsandhoes - Last Friday at 2:45 PM

how many RVN for that?

Tron - Last Friday at 2:45 PM

Rule 144 under the Securities Act of 1933 This is an important rule to be aware of in terms of privately held securities. This rule provides the most commonly used exemption for holders to sell restricted securities (Note: For context, a restricted security is a security sold in an exempt offering, except for Reg A+). The general idea is that you can publicly resell your “restricted” (privately sold) securities only when the restricted legend is removed. The solution Ravencoin Restricted Assets provides is the ability for the Iissuer to Freeze the asset ininto the holders account. The qty will be visible, and the frozen status will be visible. The meta-data for a Freeze can specify 144_Restricted. The issuer can Unfreeze to release the 144 restriction.Similar for Reg D 1-year lockup.@theking

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:46 PM

@theking ^^

DeejayQQ - Last Friday at 2:46 PM

What is the timeline for this restricted asset to be implemented?📷1

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:46 PM

No timelines yetStill in the ideation phase.

SpyderDev - Last Friday at 2:46 PM

Fresh off the press...

DeejayQQ - Last Friday at 2:46 PM

Ok, idea for nowGot it

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:46 PM

Wanting input for the idea.

boatsandhoes - Last Friday at 2:47 PM

a preset for lock up settings would be nice

Jeroz - Last Friday at 2:47 PM

What about the ability to move an asset from restricted to unrestricted after grace period similar to the reissue ability? By the issuer(edited)

boatsandhoes - Last Friday at 2:47 PM

adjustable preset*

DeejayQQ - Last Friday at 2:48 PM

If this restricted assets would help underlying token listed on exchanges for trading by satisfying the legal requirements, I don’t see why not. There are only benefits📷2

boatsandhoes - Last Friday at 2:48 PM

yeah, win win

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:48 PM

There is something similar in vote tokens.

corby - Last Friday at 2:48 PM

@Jeroz the issuer would be able to "reissue" and relax restrictions

DeejayQQ - Last Friday at 2:48 PM

Just throwing things out here. Can we just make all existing tokens crested so far restricted assets?*created

boatsandhoes - Last Friday at 2:49 PM

stupid question, is it possible to have burned rvn cost for the $ to add onto the block reward as a bonus?(edited)

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:49 PM

No, @DeejayQQ there should be both usecases available in the platform.

corby - Last Friday at 2:49 PM

We (my dog and I) are envisioning a differentiated space where we can charge a lot more RVN to keep non-serious people out..(edited)

Tron - Last Friday at 2:49 PM

@Jeroz Yes, as long as the asset is still "reissuable", you could change the logic from (#KYC & #ACCREDITED) to just #KYC📷3

Jeroz - Last Friday at 2:49 PM

I'm just worrying about the name uniqueness if you can have #BANANA and $BANANA

BW__ - Last Friday at 2:50 PM

Is it fair to assume that tags can be standardized for specific purposes? If so, should we create something akin to an 'ERC' in git repo?

Jeroz - Last Friday at 2:50 PM

@Tron sounds cool

truedev - Last Friday at 2:50 PM

honestly, I think you should be able to buy/create an asset in a set, with all types(edited)

boatsandhoes - Last Friday at 2:50 PM

^that part

Hans_Schmidt - Last Friday at 2:51 PM

Since the #KYC tag is just locked to an address, what prevents someone from selling their address and thereby the KYC?

corby - Last Friday at 2:51 PM

The "#" types won't trade -- they're just stamps to stamp addresses as qualified-to-hold-some-stuff..

Tron - Last Friday at 2:51 PM

The tags are created by the users. The system is still jurisidiction agnostic.

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:51 PM

@Hans_Schmidt nothing really, the same thing as selling your username password to any other existing financial app account.

corby - Last Friday at 2:51 PM

@Hans_Schmidt Real world networks, high cost of entry (for serious applications)For non-serious applications, nothing

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:51 PM

You still have the liability associated with that account though.

Jeroz - Last Friday at 2:52 PM

@corby what about BANANA/ vs $BANANA/ ?Or do you want to make them subassets?

boatsandhoes - Last Friday at 2:52 PM

@Jeroz better safe than sorry, just swoop both

Tron - Last Friday at 2:52 PM

A country could require that #SOMECOUNTRY tag has to exist before moving $SPECIALASSET to an address. The users set the rules. #KYC was just an example because it is an industry problem at the moment.

corby - Last Friday at 2:52 PM

#BANANA, $BANANA, TRICYCLE, and BANANA can all coexist just fine I think..

theking - Last Friday at 2:53 PM

Thanks @Tron. This is great and I think something that will enable raven to become an even more widely used platform.📷4

Tron - Last Friday at 2:53 PM

That's the hope. I think it solves some real problems that the industry is trying to solve through incompatible ERC-20 experiments.📷3

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:54 PM

/hacks📷3

boatsandhoes - Last Friday at 2:54 PM

what is the purposed cost for $ in addition to an existing asset?

corby - Last Friday at 2:54 PM

People that own #THESE I am calling "Qualifiers" -- they just stamp their mark on addresses. Issuers of $THESE need to establish trust with #THESE and #THOSE and then decide what restrictions to apply.📷1

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:54 PM

5 mins left. Stay on this topic or switch to meetup?

Tron - Last Friday at 2:55 PM

@boatsandhoes Not determined.

J. | ravenland.org - Last Friday at 2:56 PM

Can the SLC meetup made interactive for people that cant make it there?

theking - Last Friday at 2:56 PM

What about having just one name ( you first buy the standard raven token under whatever name you like) and then the holder of the owner token is the only one to create restricted tokens ? Might be some way to ensure no name confusion.📷4

boatsandhoes - Last Friday at 2:56 PM

what about that block reward bonus concept for purchasing $. would that work?

Chatturga - Last Friday at 2:56 PM

I dont know that we have the ability to make it interactive as far as Q&A goes, but I'll look into it. We should have it live streaming. @J. | ravenland.org(edited)📷2

BW__ - Last Friday at 2:56 PM

@Tron Is there same kind of logic layer to restricted assets?(edited)

Tron - Last Friday at 2:57 PM

@theking I like that idea.

Jeroz - Last Friday at 2:57 PM

Quick question that is offtopic but I think deserves an answer because it was asked a couple of times earlier this week: Will unique assets get a reissuable function? To change IPFS.(edited)📷2

Tron - Last Friday at 2:57 PM

@BW__ Yes. Simple and, or, not and parenthesis - limited in length.(edited)

boatsandhoes - Last Friday at 2:57 PM

@theking thats a good idea

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:58 PM

@Jeroz There is not a way to do that currently.

BW__ - Last Friday at 2:58 PM

@Tron That makes sense. Thank you.

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 2:58 PM

Just make sure your changes to the information have the same hash as the previous data and your golden. 📷📷1

Jeroz - Last Friday at 2:59 PM

Any plans on changing that, perhaps when introducing new types of assets?

boatsandhoes - Last Friday at 2:59 PM

i like that it cant be changed

corby - Last Friday at 3:00 PM

Thanks everyone!

theking - Last Friday at 3:00 PM

@Tron there was some info floating around about a 2nd later KYC solution ( from your recent podcast w Crypto Koala). Is that a separate solution someone is working on or part of this new concept?📷1

Tron - Last Friday at 3:01 PM

Starting with the introduction of messaging, every transaction can have an IPFS hash. Can be used as an public invoice, details about the transaction, etc.@theking The same new concept.

[Master] Roshii - Last Friday at 3:02 PM

Ok, we're done.

Steelers - Last Friday at 3:02 PM

How would Raven handle for instance a stock split?

BW__ - Last Friday at 3:02 PM

Are there sync concerns if a restricted asset logic layer is added?

Tron - Last Friday at 3:02 PM

@theking The KYC provider would store the KYC info, and send the Tag to an address with meta data that specifies that they're holding the KYC data. The KYC data would not be public, but could be audited.

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 3:02 PM

That way you could update information about the original unique asset with each transaction.@Steelers Just a simple re-issue of the asset

Tron - Last Friday at 3:03 PM

@bw_ The logic layer is only a small db that stores the meta-data about the Restricted Asset, and enforces the restriction in the consensus rules. Rule returns true/false.(edited)

RavencoinDev (Jesse/Wolfsokta) - Last Friday at 3:03 PM

Thanks everybody! I have to run.

Jeroz - Last Friday at 3:04 PM

I'm looking forward to the discussions to let this take shape. Thanks all! 📷📷4

Tron - Last Friday at 3:05 PM

@BW__ It would work very similarly to the way the units works now. Each asset has number of units and any transaction that makes it too granular (more satoshis) will fail in consensus -- even if it gets past the RPC checks.Signing off. Thanks all!!!📷9📷4📷9

Ravencoin Open Developer Meeting - 1/4/2019

[14:04] Hi everyone! [14:04] :dabbitwave: [14:04] Hey Everybody! [14:04] Hello 😃 [14:04] Sorry we're getting started a bit late. [14:04] Topics: SLC Meetup (March 15th) [14:04] 👋 [14:04] Roadmap breakdown - posted to github [14:05] IPFS (integration) [14:05] greetings 👋 [14:05] So, SLC Meetup on the 15th! [14:05] Great! [14:05] Hi! [14:06] Hi all — a special thanks to the developers and congratulations on an amazing first year!!! # [14:06] <[Dev] Blondfrogs> Hello Everyone! [14:07] We have a tentative agenda with @Tron , @corby speaking. [14:08] We would like to have nice walkthrough of the Raven DevKit for the meetup. [14:08] We are planning on hosting a meetup in SLC at the Overstock building on March 15th from 6:00pm-9:00pm. It is free admission, but there is a page on meetup.com where people can rsvp so that we have a somewhat accurate headcount for food. [14:08] sup guys [14:08] hey russ [14:09] We are planning on having a few speakers and have allotted a bit of time at the end for people to meet and greet each other. [14:09] can you guys link us to the page somewhere when thats available? 😄 [14:10] free food?! [14:10] todays topic? [14:10] yeah can we indicate pepperoni pizza [14:10] Sounds good to me @Jeroz Nothing ordered yet though. 😃 [14:10] only pepperoni pizza is served at true blockchain meetings right [14:10] :blobhide: [14:10] Absolutely. The itinerary just needs to be finalized and then I'll make a broad post about the rest of the details. [14:11] https://www.meetup.com/Salt-Lake-City-salt-lake-city-Meetup/ [14:11] 😭 so far away [14:11] West Coast! [14:11] @MTarget But there's pizza, so worth the travel time. [14:11] lol [14:12] I'll be watching the stream if its available since i'm from montreal/canada 😛 [14:12] Ah yes, I love $300 pizza 😉 [14:12] as long as I get to see your smiling faces @Tron @RavencoinDev then it's worth the time [14:12] We'll be there. [14:12] We'll be messaging additional details as they get finalized. [14:12] Greeting and salutations! [14:12] sup [14:13] Hey, $300 is considerably cheaper than 2 $3,700,000 pizzas. [14:14] Ok, switching topics... [14:14] yeah its a way to fly, [14:14] question is whether those piza's will be paid for in RVN coin or not :ThinkBlack: [14:14] Roadmap [14:14] It hasn't changed, just added some detail. [14:14] https://github.com/RavenProject/Ravencoin/tree/masteroadmap [14:15] nice [14:15] This now links to a breakdown for messaging, voting, anti-spam, and rewards (dividends) [14:15] will there be any additional RPC functionality coming in the future, thinking in terms of some functions that are only available in ravencore-lib [14:15] apologies if now is not time to ask questions, i can wait for later [14:15] "Phase 7 - Compatibility Mode" - that's new 😮 [14:15] The protocol for messaging is pretty well established, but the rest isn't in stone (code) yet. [14:16] can you give us details on compatibility mode? [14:16] In broad brush strokes. [14:17] The idea is to allow ravend to act as a daemon that looks like a single coin. [14:17] so ravend that only works with the bitcoin asset? [14:18] interesting [14:19] So you start it with an option to only work with a single asset/token account or something? [14:19] hmm compelling what is the reason for this? some kind of scale or performance? [14:19] ^ [14:19] Example: Configure ravend to listen for transfer RPC call for senttoaddress or sendfrom, but for a specific asset. This would allow easy integration into existing system for assets. [14:20] Only the daemon or the whole wallet UI? [14:20] yeah thats great, rpc functions dont allow us to do this yet, if i recall [14:20] or at least we depend more on ravencore lib [14:20] so like asset zmq [14:20] that's smart [14:20] @Tron it also sounds like it makes our life easier working with RPC, instead of core all the time for some functionality [14:21] if i understand correctly anyways [14:21] So you could run numerous instances of ravend each on their own network and RPC port, each configured for a different asset. You would need some balance of RVN in each one to cover transaction fees, then. [14:21] id be curious to know what all the advantages are of this [14:21] one more question, how would i decentralize the gateway between bitcoin mainnet/ravencoin mainnet? in the current RSK implementation they use a federated gateway, how would we avoid this? [14:21] it sounds neato [14:21] Just the daemon. The alternative is to get exchanges to adapt to our RPC calls for assets. It is easier if it just looks like Bitcoin, Litecoin or RVN to them, but it is really transferring FREE_HUGS [14:22] That makes sense. Should further increased exchange adoption for each asset. [14:22] hmm yeah its just easier for wallet integration because its basically the same as rvn and bitcoin but for a specific asset [14:22] so this is in specific mind of exchange listings for assets i guess [14:23] if i understand rightly [14:23] @traysi Gut feel is to allow ravend to handle a few different assets on different threads. [14:23] Are you going to call it kawmeleon mode? [14:23] Lol [14:23] I read that as kaw-melon mode. [14:24] same lol [14:24] so in one single swoop it possible to create a specific wallet and server daemon for specific assets. great. this makes it easier for exchanges, and has some added advantages with processing data too right? [14:24] Still keeping a RVN balance in the wallet, as well, Tron. How will that work is sendtoaddress sends the token instead of the RVN? A receive-RVN/send tokens-only wallet? [14:25] @traysi Yes [14:25] sendtoaddress on the other port (non RVN port) would send the asset. [14:25] This will be a hugely useful feature. [14:25] ^ [14:26] @Tron currently rpc function not support getaddresses senttowallet and this has to be done in ravencore lib, will this change you propose improve this situation [14:26] Config might look like {"port":2222, "asset":"FREE_HUGS", "rpcuser":"hugger", "rpcpass":"gi3afja33"} [14:26] how will this work cross-chain? [14:28] @push We'd have to go through the rpc calls and work out which ones are supported in compatibility mode. Obviously the mining ones don't apply. And some are generic like getinfo. [14:28] ok cool 👍 cheers [14:29] for now we continue using ravencore lib for our plans to keep track i just wondering if better way [14:29] as we had some issue after realising no rpc function for getting addresses of people who had sent rvn [14:29] @push | ravenland.org all of the node explorer and ravencore-lib functionality is based on RPC (including the addressindex-related calls). Nothing you can't do with RPC, although I'm not sure of the use cases you're referring to.. [14:29] interesting, so ravencore lib is using getrawtransaction somehow [14:29] i thought this may be the case [14:29] that is very useful thankyou for sharing this [14:30] look into addressindex flag and related RPC calls for functions that operate on addresses outside your wallet [14:30] thank you that is very useful, tbh i am not very skilled programmer so just decoding the hex at the raven-cli commandline was a challenge, i shall look more into this, valued information thanks as this was a big ? for us [14:31] Ok, things have gone quiet. New topic. [14:31] IPFS (integration) [14:31] GO [14:33] ... [14:33] <[Dev] Blondfrogs> So, we have been adding ipfs integration into the wallet for messaging. This will allow the wallets to do some pretty sweet stuff. For instance, you will be able to create your ipfs data file for issuing an asset. Push it to ipfs from the wallet, and add the hash right into the issuance data. This is going to allow for a much more seamless flow into the app. [14:34] <[Dev] Blondfrogs> This ofcourse, will also allow for users to create messages, and post them on ipfs and be able to easily and quickly format and send messages out on the network with ipfs data. [14:34] It will also allow optional meta-data with each transaction that goes in IPFS. [14:34] will i be able to view ipfs images natively in the wallet? [14:34] <[Dev] Blondfrogs> Images no [14:34] We discussed the option to disable all IPFS integration also. [14:35] @russ (kb: russkidooski) Probably not. There's some risk to being an image viewer for ANY data. [14:35] No option in wallet to opt into image viewing? [14:35] cool so drag and drop ipfs , if someone wanted to attach an object like an image or a file they could drag drop into ui and it create hash and attach string to transaction command parameters automatically [14:35] We could probably provide a link -- with a warning. [14:35] nomore going to globalupload.io [14:35] :ThinkBlack: [14:35] I understand that the wallet will rely on globalupload.io. (phase 1). Is it not dangerous to rely on an external network? Or am I missing something? [14:36] hmm [14:36] interesting, i suppose you could hash at two different endpoints and compare them [14:36] if you were that worried [14:36] and only submit one to the chain [14:36] You will be able to configure a URL that will be used as an IPFS browser. [14:36] Oh ic [14:36] you wont flood ipfs because only one hash per unique file [14:36] <[Dev] Blondfrogs> There are multiple options for ipfs integration. We are building it so you can run your own ipfs node locally. [14:36] <[Dev] Blondfrogs> or, point it to whatever service you would like. e.g. cloudflare [14:36] this is very cool developments, great to see this [14:37] Just like the external block explorer link currently in preferences. [14:37] @[Dev] Blondfrogs what about a native ipfs swarm for ravencoin only? [14:37] We have discussed that as an option. [14:37] @push | ravenland.org Considering having a fallback of upload through globalupload.io and download through cloudflare. [14:37] <[Dev] Blondfrogs> @russ (kb: russkidooski) We talked about that, but no decisions have been made yet. [14:37] yeah, i would just use two endpoints and strcompare the hash [14:37] as long as they agree good [14:37] submit tran [14:38] else 'potentially mysterious activity' [14:38] ? [14:38] if you submitted the file to ipfs api endpoints [14:38] Will the metadata just be a form with text only fields? [14:39] and then you would get 2 hashes, from 2 independent services [14:39] that way you would not be relying on a central hash service [14:39] and have some means of checking if a returned hash value was intercepted or transformed [14:39] i was answering jeroz' question [14:40] about relying on a single api endpoint for upload ipfs object [14:40] We have also kicked around the idea of hosting our own JSON only IPFS upload/browse service. [14:41] I have a service like this that is simple using php [14:41] we only use it for images right now [14:41] but fairly easy to do [14:41] Yup [14:42] Further questions about IPFS? [14:43] contract handling? file attach handling? or just text fields to generate json? [14:44] trying to get an idea of what the wallet will offer for attaching data [14:44] Probably just text fields that meet the meta-data spec. [14:44] ok noted [14:44] What do you mean by contract handling @sull [14:45] We won't prevent other hashes from being added. [14:45] asset contract (pdf etc) hash etc [14:45] <[Dev] Blondfrogs> also, being able to load from a file [14:45] got it, thanks [14:47] Let's do some general Q&A [14:48] Maybe just a heads up or something to look for in the future but as of right now, it takes roughly 12 hours to sync up the Qt-wallet from scratch. Did a clean installation on my linux PC last night. [14:48] Any plans or discussions related to lack of privacy of asset transfers and the ability to front run when sending to an exchange? [14:48] ^ [14:48] Is there a way to apply to help moderate for example the Telegram / Discord, i spend alot of time on both places, sometimes i pm mods if needed. [14:49] Any developed plans for Asset TX fee adjustment? [14:49] also this^ [14:49] @mxL86 We just created a card on the public board to look into that. [14:49] General remark: https://raven.wiki/wiki/Development#Phase_7_-_Compatible_Mode = updated reflecting Tron's explanation. [14:49] @mxL86 That's a great question. We need to do some profiling and speed it up. I do know that the fix we added from Bitcoin (that saved our bacon) slowed things down. [14:50] Adding to @mxL86 the sync times substantially increased coinciding with the asset layer activation. Please run some internal benchmarks and see where the daemon is wasting all its cycles on each block. We should be able to handle dozens per second but it takes a couple seconds per block. [14:50] @BW__ no plans currently for zk proofs or anything if that's what you're asking [14:50] You are doing a great job. Is there a plan that all this things (IPFS) could be some day implemented in mobile wallet? Or just in QT? [14:50] i notice also that asset transactions had some effect on sync time as we were making a few. Some spikes i not analysed the io and cpu activity properly but will if there is interest [14:51] we are testing some stuff so run into things i am happy to share [14:51] @BW__ Might look at Grin and Beam to see if we can integrate Mimble Wimble -- down the road. [14:51] yeees [14:51] @J. | ravenland.org work with the telegram mods. Not something the developers handle. [14:51] i love you [14:51] @J. | ravenland.org That would be best brought up with the operators/mods of teh telegram channel. [14:51] @corby @Tron thnx [14:51] @S1LVA | GetRavencoin.org we're planning on bumping fees to... something higher! [14:51] no catastrophic failures, just some transaction too smals, and mempool issues so far, still learning [14:52] @corby i thought that this may happen :ThinkBlack: [14:52] @corby x10? 100x? 1000x? Ballpark? [14:52] Definitely ballpark. [14:52] 😃 [14:52] 😂 [14:52] Is a ballpark like a googolplex? [14:53] @push | ravenland.org asset transactions are definitely more expensive to sync [14:53] yes yes they are [14:53] they are also more expensive to make i believe [14:53] 10,000x! [14:53] as some sync process seems to occur before they are done [14:53] @traysi ★★★★★ thanks for the suggestions we are going to be looking at optimizations [14:53] But, it is way slower than we like. Going to look into it. [14:53] i do not understand fully its operation [14:53] 1000x at minimum in my opinion [14:53] its too easy to spam the network [14:54] yes there has been some reports of ahem spam lately [14:54] :blobhide: [14:54] 😉 [14:54] cough cough ravenland [14:54] @russ (kb: russkidooski) we're in agreement -- it's too low [14:54] default fee 0.001 [14:54] ^ something around here [14:54] @corby yep we all are i think [14:55] waaay too low [14:55] meaningful transactions start with meaningful capital expense [14:55] though there is another scenario , there are some larger volume, more objective rich use cases of the chain that would suffer considerably from that [14:55] just worth mentioning, as i have beeen thinking about this a lot [14:55] there are some way around, like i could add 1000 ipfs hashes to a single unique entity, i tested this and it does work [14:56] @russ (kb: russkidooski) What would you suggest. [14:57] I had a PR for fee increase and push back. [14:57] Ignore the push back. 0.001 RVN is not even a micro-farthing in fiat terms [14:57] definitely around 1000x [14:57] Vocal minority for sure [14:57] ^ yep [14:57] @russ (kb: russkidooski) That sounds reasonable. [14:57] Couple hundred Fentons [14:58] right now an asset transaction is 0.01 of a penny essentially [14:58] 1 RVN would work now, but not when RVN is over $1. [14:58] yes exactly [14:58] Hi. Late to the party. [14:58] We are also talking about a min fee. The system will auto-adapt if blocks fill up. [14:58] im thinking tron, some heavy transaction use cases would fall out of utility use if that happened [14:58] so whats the thinking there [14:59] is there a way around the problem, bulked ipfs hash transactions? [14:59] 1000x would put us around btc levels [14:59] maybe a minimum 500x? [14:59] @russ (kb: russkidooski) Agreed. [14:59] <[Dev] Blondfrogs> It is time to wrap it up here. Everyone. Thank you all for your questions and thoughts. We will be back in 2 weeks. 😃 [14:59] Small increase and review. [14:59] Thanks all! [14:59] Cheers. [15:00] yeah sorry for 1 million questions guys hope i didnt take up too much time [15:00] cheers all 👍 [15:00] Thanks everyone [15:00] Thanks everyone for participating!!! [15:00] That is what we are here for [15:00] 100x-500x increase, 1000x maximum [15:00] 🍺
