Batch script to create pruned block data from full block data

TLDR; Produce a pruned block directory from a full block directory without copying any extra block data
I have a full node, but at times I want to run in a VM or on a RPi or something. Normally I have to clone my whole 300 GB block directory, enable pruning, then point bitcoin-qt.exe to the clone to finally arrive at a small 4 GB datadir. I found it frustrating that I was doing this 295 GB of pointless copy operations since once I enable pruning, the old blocks are discarded. I was also discouraged at the fact that .\Bitcoin\testnet3\blocks\blk00186.dat is different (by checksum) in a pruned and non-pruned directory.
So I finally came up with an answer. Basically, I copy over the latest few blk*.dat and rev*.dat files, then just make empty copies of the other blk*.dat and rev*.dat files. Then once bitcoin-qt.exe launches, it discards the empty files and rewrites the few files it needs. For Windows, it looks something like this:
set /a "sum=0" for /f %%I in ('dir /s /b /o:-n %full_blk%\blk*.dat') do ( set size=%%~zI set blkdat=%%~nxI set revdat=!blkdat:blk=rev! if !sum! GTR !pruned_mb! ( echo.> %pruned_blk%\!blkdat! echo.> %pruned_blk%\!revdat! ) else ( copy %full_blk%\!blkdat! %pruned_blk%\!blkdat! copy %full_blk%\!revdat! %pruned_blk%\!revdat! ) set /a "sum=!sum! -1 + !size!/(1024*1024)" )
I can stamp out a pruned blocks directory from my full blocks directory in seconds. Much easier... well for me.
Here's the source, but no guarantees. Just food for thought.
 
Update: I had originally thought to symlink the unused files, but turns out they are never read at all, so I can just dummy them out.

[DEVELOPMENT] Bitcoind IPV4 testnet port (18332) is failing to bind

[SOLVED] Thanks for everyone that have helped!


Hello everyone, this is a development problem that I'm currently having. Since the BTC Development sub is kind of inactive and I couldn't find any rule contraty to posting about BTC Development, I'll try my luck in here as I'm hopeless already. I've posted on BTC Stack Exchange but no answers also. Please, don't get me wrong, I'm trying to solve this problem for many days now, I've looked up everywhere for this.
I'm new to Bitcoin development and I'm currently having difficulties trying to make RPC calls from a Docker Container to a Bitcoin-Core daemon running in a SSH server. I suppose that the problem may be with Firewall or closed ports, but I also do not know much about Network settings.
I'm using nbobtc/bitcoind-php package to make the RPC calls with HTTP requests, and it is running in a Docker container. I'm sure the container is functional and is not the problem.
So here's what happening: when I run bitcoind in root user (but normal also won't work) in my SSH server, the IPV4 testnet port seems to be not opened. This message goes up when I run bitcoind:
Binding RPC on address 0.0.0.0 port 18332 failed.
Here's what my bitcoin.conf looks like (I want to use testnet in here). I'm using Bitcoin-Core "subversion": "Satoshi:0.17.1".
server=1 debug=net txindex=1 testnet=1 rpcuser=userb rpcpassword=test test.rpcport=18332 # I've already tried allowing the IP these 3 ways: # rpcallowip=192.168.xx.xx # My machine's IP # rpcallowip=172.19.x.x/xx # Docker's NBOBTC container IP # rpcallowip=0.0.0.0/0 # Allowing all IP datadir=/home/bitcoin-dev/.bitcoin debuglogfile=/home/bitcoin-dev/.bitcoin/debug.log 
Here's what appears in debug.log right after I run Bitcoind:

After all that appears above, there are just "UpdateTip", "Requesting block", "received block" and "getdata" messages. (so the P2P port, 18333, works).

And here is when I netstat:

sudo netstat -nap|grep bitcoin|grep LISTEN
tcp 0 0 0.0.0.0:18333 0.0.0.0:* LISTEN 31185/bitcoind tcp6 0 0 :::18332 :::* LISTEN 31185/bitcoind tcp6 0 0 :::18333 :::* LISTEN 31185/bitcoind 
Thank you in advance!

PS: A few days ago I could make it work when running bitcoind with root user, but now even that won't solve the problem.

Found an old wallet.dat. What are the chances of anything being in it?

I was thinking of formatting my macbook and decided to search for wallet.dat's in case there's anything of value here that I forgot about.
Looks like back in 2013 I went through a bit of an experimental phase with cryptos:
/Users/john/Library/Application Support/Bitcoin/testnet3/wallet.dat /Users/john/Library/Application Support/Bitcoin/wallet.dat /Users/john/Library/Application Support/Feathercoin/wallet.dat /Users/john/Library/Application Support/Litecoin/wallet.dat /Users/john/Library/Application Support/PPCoin/wallet.dat 
Some look empty but Litecoin's wallet is 66KB.
Also in the same folder was this rather large debug log: https://filebin.ca/3lHXLzox4EzS/debug.log
It looks like I was just downloading the block chain but I'm wondering if anyone who is more familiar with Litecoin sees anything of interest in there?
Is it worth trying to recover? How difficult is this process? Is wallet.dat still compatible with the latest version of Litecoin?

Testnet helpers, make your debug logs available again for us and add bandwidth metering with this

Make sure your node is logging data properly.
The following instructions are for Debian 8.2 (jessie). You may have to make some adjustments for other OSes. Post a comment if you have trouble.
Run these lines:
sudo apt-get install lighttpd tcpstat sudo touch /vawww/html/debug-filtered.log.gz sudo touch /vawww/html/bw.log sudo chown `whoami`.`whoami` /vawww/html/debug-filtered.log.gz sudo chown `whoami`.`whoami` /vawww/html/bw.log 
You may want to do the first line by itself to get through the password prompt before pasting in the other lines. Also, you might end up using /vawww/ instead of /vawww/html/, depending on your server and configuration.
Next, run crontab -e and add this line at the bottom:
31 */2 * * * grep -v "eject " ~/.bitcoin/testnet3/debug.log | grep -v " tx " | grep -v "received: inv" | grep -v "sending: inv" | grep -v "received: getdata" | grep -v "received getdata" | grep -v "AcceptToMemoryPool" | gzip > /vawww/html/debug-filtered.log.gz 
That should compress the log files down to around 1 to 5% of their original size, rewriting it every hour. This compression will take about 1 minute (every 2 hours at 31 minutes past the hour) on most machines. If it takes too much CPU on your machine, you can reduce the frequency by changing the */2 to something like */4 (once every 4 hours).
Check to make sure you have the right version of tcpstat. There are two different programs with the same name:
sudo tcpstat -h | grep tcpstat # should say "tcpstat version 1.5", not "tcpstat 0.1 (c) J. Taimisto 2005-2013" 
If you have the wrong version, you should go to http://www.frenchfries.net/paul/tcpstat/ and rebuild from source.
Next, run this every time your machine is restarted either in a screen or in the background:
giface=eth0 # unless it's not sudo tcpstat -f "port 18333" -o "%s,\t%B\n" -i $giface 0.1 -F > /vawww/html/bw.log 
Open port 80 on your firewall if necessary. Then tell me your IP address (and optionally add it to the spreadsheet), and I'll grab the log files and include them in my analyses.
Edit: added AcceptToMemoryPool filter.
Edit2: Changed paths to /vawww/html/ for the lighttpd default.

Alternative chain support for payment protocol | Ross Nicoll | Aug 09 2015

Ross Nicoll on Aug 09 2015:
BIP 70 currently lists two networks, main and test (inferred as
testnet3) for payment protocol requests. This means that different
testnets cannot be supported trivially, and the protocol cannot be used
for alternative coins (or, lacks context to indicate which coin the
request applies to, which is particularly dangerous in cases where coins
share address prefixes).
I propose adding a new optional "genesis" field as a 16 byte sequence
containing the SHA-256 hash of the genesis block of the network the
request belongs to, uniquely identifying chains without any requirement
for a central registry. For backwards compatibility, the "network" field
would contain "main" for Bitcoin main net, "test" for Bitcoin testnet3,
and "other" for other networks apart from those two.
I'd appreciate initial feedback on the idea, and if there's no major
objections I'll raise this as a BIP.

Scalenet and Testnet4 are online and open for business

Over the years, some people have made use of testnet3 to test out scaling performance, and have spammed testnet3 with 32 MB blocks. This has caused testnet3 to get kinda bloated; the blockchain now takes an hour or so to sync, which slows down development. Other people have wanted to do stress testing, but have specifically wanted to avoid inconveniencing other people by spamming testnet3, and have therefore not done so. This slows down development too. To address this issue, I created two new networks: testnet4 and scalenet.
Testnet4 is intended to be a low-volume quick-syncing blockchain which is ideal for testing out new transaction formats or applications. It has a 2 MB default block size limit, and comes with aserti3 parameters that make the difficulty recover quickly to CPU-mineable levels. It should remain easy to sync on a low-end VPS or old laptop.
Scalenet is intended to be a high-volume blockchain which is ideal for spamming and stress testing software. It comes with a 256 MB initial default block size limit, and uses aserti3 parameters that make it more suitable for accurately simulating mainnet mining difficulty (though it retains the 20-minute difficulty rule). In order to prevent storage costs from getting unreasonable for a testnet, scalenet will be reset every 6-12 months by invalidating the block at height 10,001 and adding a new checkpoint. Scalenet is intended to be feasible to run on a mid-range desktop computer with some strain.
Testnet4 and scalenet are now online and essentially complete. The code for both has been merged into BCHN and Electron Cash. Testnet4 has also been successfully synced to by Knuth, Bitcoin Unlimited, and libbitcoincashj. Block explorers for both are available, thanks to Axel Gembe (who runs the code) and sickpig (who wrote the code):
http://tbch4.loping.net:3002/
http://sbch.loping.net:3003/
The testnet4 and scalenet MRs were opened on Aug 19th and Aug 27th, and both were merged on Sep 17th. Scalenet reached height 10,000 on October 3rd.
Testnet4 and Scalenet support are present in the master branch of BCHN, and will be included in the next release of BCHN. Some other software (e.g. Electron Cash) already has support in their latest release, but most is still pending.

Anatomy of the Bitcoin Node filesystem

There are man explanations like this, but this one is mine.
Just in case anyone was curious. I dug up some good posts on this and thought I'd distill it as best I could. I'll be using Windows file separators, but fee free to change them in your head.
If you name a -datadir argument, this is what will land there. If one is not named it defaults to %APPDATA%\Bitcoin
If you name a -blocksdir argument, this is what will land there. If one is not named it defaults to
If you name a -walletdir argument, this is what will land there. If one is not named it defaults to \wallets or just if the wallets subdirectory doesn't exist.
  • \wallet.dat - The wallet file with private keys and UTXOs
  • \db.log - Database log of access to wallet
Note that -datadir, -blocksdir and -walletdir can all point to different storage. The things you need to keep in mind:
  1. -datadir should be your FASTEST storage
  2. -blocksdir should be your LARGEST storage
  3. -walletdir should be your most SECURE storage
As a footnote, -testnet will throw a testnet3\ in everything, and -walletdir would be assumed to refer to test.walletdir

Decred Journal – August 2018

Note: you can read this on GitHub (link), Medium (link) or old Reddit (link) to see all the links.

Development

dcrd: Version 1.3.0 RC1 (Release Candidate 1) is out! The main features of this release are significant performance improvements, including some that benefit SPV clients. Full release notes and downloads are on GitHub.
The default minimum transaction fee rate was reduced from 0.001 to 0.0001 DCkB. Do not try to send such small fee transactions just yet, until the majority of the network upgrades.
Release process was changed to use release branches and bump version on the master branch at the beginning of a release cycle. Discussed in this chat.
The codebase is ready for the new Go 1.11 version. Migration to vgo module system is complete and the 1.4.0 release will be built using modules. The list of versioned modules and a hierarchy diagram are available here.
The testnet was reset and bumped to version 3.
Comments are welcome for the proposal to implement smart fee estimation, which is important for Lightning Network.
@matheusd recorded a code review video for new Decred developers that explains how tickets are selected for voting.
dcrwallet: Version 1.3.0 RC1 features new SPV sync mode, new ticket buyer, new APIs for Decrediton and a host of bug fixes. On the dev side, dcrwallet also migrated to the new module system.
Decrediton: Version 1.3.0 RC1 adds the new SPV sync mode that syncs roughly 5x faster. The feature is off by default while it receives more testing from experienced users. Other notable changes include a design polish and experimental Politeia integration.
Politeia: Proposal editing is being developed and has a short demo. This will allow proposal owners to edit their proposal in response to community feedback before voting begins. The challenges associated with this feature relate to updating censorship tokens and maintaining a clear history of which version comments were made on. @fernandoabolafio produced this architecture diagram which may be of interest to developers.
@degeri joined to perform security testing of Politeia and found several issues.
dcrdata: mainnet explorer upgraded to v2.1 with several new features. For users: credit/debit tx filter on address page, showing miner fees on coinbase transaction page, estimate yearly ticket rewards on main page, cool new hamburger menu and keyboard navigation. For developers: new chain parameters page, experimental Insight API support, endpoints for coin supply and block rewards, testnet3 support. Lots of minor API changes and frontend tweaks, many bug fixes and robustness improvements.
The upcoming v3.0 entered beta and is deployed on beta.dcrdata.org. Check out the new charts page. Feedback and bug reports are appreciated. Finally, the development version v3.1.0-pre is on alpha.dcrdata.org.
Android: updated to be compatible with the latest SPV code and is syncing, several performance issues are worked on. Details were posted in chat. Alpha testing has started, to participate please join #dev and ask for the APK.
iOS: backend is mostly complete, as well as the front end. Support for devices with smaller screens was improved. What works now: creating and recovering wallets, listing of transactions, receiving DCR, displaying and scanning QR codes, browsing account information, SPV connection to peers, downloading headers. Some bugs need fixing before making testable builds.
Ticket splitting: v0.6.0 beta released with improved fee calculation and multiple bug fixes.
docs: introduced new Governance section that grouped some old articles as well as the new Politeia page.
@Richard-Red created a concept repository sandbox with policy documents, to illustrate the kind of policies that could be approved and amended by Politeia proposals.
decred.org: 8 contributors added and 4 removed, including 2 advisors (discussion here).
decredmarketcap.com is a brand new website that shows the most accurate DCR market data. Clean design, mobile friendly, no javascript required.
Dev activity stats for August: 239 active PRs, 219 commits, 25k added and 11k deleted lines spread across 8 repositories. Contributions came from 2-10 developers per repository. (chart)

Network

Hashrate: went from 54 to 76 PH/s, the low was 50 and the new all-time high is 100 PH/s. BeePool share rose to ~50% while F2Pool shrank to 30%, followed by coinmine.pl at 5% and Luxor at 3%.
Staking: 30-day average ticket price is 95.6 DCR (+3.0) as of Sep 3. During the month, ticket price fluctuated between a low of 92.2 and high of 100.5 DCR. Locked DCR represented between 3.8 and 3.9 million or 46.3-46.9% of the supply.
Nodes: there are 217 public listening and 281 normal nodes per dcred.eu. Version distribution: 2% at v1.4.0(pre) (dev builds), 5% on v1.3.0 (RC1), 62% on v1.2.0 (-5%), 22% on v1.1.2 (-2%), 6% on v1.1.0 (-1%). Almost 69% of nodes are v.1.2.0 and higher and support client filters. Data snapshot of Aug 31.

ASICs

Obelisk posted 3 email updates in August. DCR1 units are reportedly shipping with 1 TH/s hashrate and will be upgraded with firmware to 1.5 TH/s. Batch 1 customers will receive compensation for missed shipment dates, but only after Batch 5 ships. Batch 2-5 customers will be receiving the updated slim design.
Innosilicon announced the new D9+ DecredMaster: 2.8 TH/s at 1,230 W priced $1,499. Specified shipping date was Aug 10-15.
FFMiner DS19 claims 3.1 TH/s for Blake256R14 at 680 W and simultaneously 1.55 TH/s for Blake2B at 410 W, the price is $1,299. Shipping Aug 20-25.
Another newly noticed miner offer is this unit that does 46 TH/s at 2,150 W at the price of $4,720. It is shipping Nov 2018 and the stats look very close to Pangolin Whatsminer DCR (which has now a page on asicminervalue).

Integrations

www.d1pool.com joined the list of stakepools for a total of 16.
Australian CoinTree added DCR trading. The platform supports fiat, there are some limitations during the upgrade to a new system but also no fees in the "Early access mode". On a related note, CoinTree is working on a feature to pay household bills with cryptocurrencies it supports.
Three new OTC desks were added to exchanges page at decred.org.
Two mobile wallets integrated Decred:
Reminder: do your best to understand the security and privacy model before using any wallet software. Points to consider: who controls the seed, does the wallet talk to the nodes directly or via middlemen, is it open source or not?

Adoption

Merchants:

Marketing

Targeted advertising report for August was posted by @timhebel. Facebook appeal is pending, some Google and Twitter campaigns were paused and some updated. Read more here.
Contribution to the @decredproject Twitter account has evolved over the past few months. A #twitter_ops channel is being used on Matrix to collaboratively draft and execute project account tweets (including retweets). Anyone with an interest in contributing to the Twitter account can ask for an invitation to the channel and can start contributing content and ideas there for evaluation by the Twitter group. As a result, no minority or unilateral veto over tweets is possible. (from GitHub)

Events

Attended:
For those willing to help with the events:
BAB: Hey all, we are gearing up for conference season. I have a list of places we hope to attend but need to know who besides @joshuam and @Haon are willing to do public speaking, willing to work booths, or help out at them? You will need to be well versed on not just what is Decred, but the history of Decred etc... DM me if you are interested. (#event_planning)
The Decred project is looking for ambassadors. If you are looking for a fun cryptocurrency to get involved in send me a DM or come talk to me on Decred slack. (@marco_peereboom, longer version here)

Media

Decred Assembly episode 21 is available. @jy-p and lead dcrwallet developer @jrick discussed SPV from Satoshi's whitepaper, how it can be improved upon and what's coming in Decred.
Decred Assembly episodes 1-21 are available in audio only format here.
New instructional articles on stakey.club: Decrediton setup, Deleting the wallet, Installing Go, Installing dcrd, dcrd as a Linux service. Available in both English and Portuguese.
Decred scored #32 in the August issue of Chinese CCID ratings. The evaluation model was explained in this interview.
Satis Group rated Decred highly in their cryptoasset valuation research report (PDF). This was featured by several large media outlets, but some did not link to or omitted Decred entirely, citing low market cap.

Community Discussions

Community stats:
Comm systems news:
After another debate about chat systems more people began testing and using Matrix, leading to some gardening on that platform:
Highlights:
Reddit: substantive discussion about Decred cons; ecosystem fund; a thread about voter engagement, Politeia UX and trolling; idea of a social media system for Decred by @michae2xl; how profitable is the Obelisk DCR1.
Chats: cross-chain trading via LN; plans for contractor management system, lower-level decision making and contractor privacy vs transparency for stakeholders; measuring dev activity; what if the network stalls, multiple implementations of Decred for more resilience, long term vision behind those extensive tests and accurate comments in the codebase; ideas for process for policy documents, hosting them in Pi and approving with ticket voting; about SPV wallet disk size, how compact filters work; odds of a wallet fetching a wrong block in SPV; new module system in Go; security of allowing Android app backups; why PoW algo change proposal must be specified in great detail; thoughts about NIPoPoWs and SPV; prerequisites for shipping SPV by default (continued); Decred vs Dash treasury and marketing expenses, spending other people's money; why Decred should not invade a country, DAO and nation states, entangling with nation state is poor resource allocation; how winning tickets are determined and attack vectors; Politeia proposal moderation, contractor clearance, the scale of proposals and decision delegation, initial Politeia vote to approve Politeia itself; chat systems, Matrix/Slack/Discord/RocketChat/Keybase (continued); overview of Korean exchanges; no breaking changes in vgo; why project fund burn rate must keep low; asymptotic behavior of Decred and other ccs, tail emission; count of full nodes and incentives to run them; Politeia proposal translations and multilingual environment.
An unusual event was the chat about double negatives and other oddities in languages in #trading.

Markets

DCR started the month at USD 56 / BTC 0.0073 and had a two week decline. On Aug 14 the whole market took a huge drop and briefly went below USD 200 billion. Bitcoin went below USD 6,000 and top 100 cryptos lost 5-30%. The lowest point coincided with Bitcoin dominance peak at 54.5%. On that day Decred dived -17% and reached the bottom of USD 32 / BTC 0.00537. Since then it went sideways in the USD 35-45 / BTC 0.0054-0.0064 range. Around Aug 24, Huobi showed DCR trading volume above USD 5M and this coincided with a minor recovery.
@ImacallyouJawdy posted some creative analysis based on ticket data.

Relevant External

StopAndDecrypt published an extensive article "ASIC Resistance is Nothing but a Blockchain Buzzword" that is much in line with Decred's stance on ASICs.
The ongoing debates about the possible Sia fork yet again demonstrate the importance of a robust dispute resolution mechanism. Also, we are lucky to have the treasury.
Mark B Lundeberg, who found a vulnerability in atomicswap earlier, published a concept of more private peer-to-peer atomic swaps. (missed in July issue)
Medium took a cautious stance on cryptocurrencies and triggered at least one project to migrate to Ghost (that same project previously migrated away from Slack).
Regulation: Vietnam bans mining equipment imports, China halts crypto events and tightens control of crypto chat groups.
Reddit was hacked by intercepting 2FA codes sent via SMS. The announcement explains the impact. Yet another data breach suggests to think twice before sharing any data with any company and shift to more secure authentication systems.
Intel and x86 dumpsterfire keeps burning brighter. Seek more secure hardware and operating systems for your coins.
Finally, unrelated to Decred but good for a laugh: yetanotherico.com.
