#namecoin-meeting notes, 2016 08 21 # Present: Jeremy Jonas Brandon Midnightmagic Pigeons Joseph Namecoin Core The wallet name operation bug in Brandon's name tab PR has been isolated by Jeremy. Appears to be a bug in upstream Bitcoin Core (or perhaps Namecoin Core master branch) that has been fixed. https://github.com/namecoin/namecoin-core/pull/67#issuecomment-231316792 Whit Jackson submitted a documentation PR for building on OS X. https://github.com/namecoin/namecoin-core/pull/97 If anyone can test, please do so! Jonas will test this. Jeremy noticed that Travis CI accidentally flagged our repo as "potential abuse detected". Jeremy contacted Travis CI support and got our account whitelisted. Jonas notices that the Travis CI builds for our 0.13 branch are failing at the moment. Jeremy suggests filing a GitHub issue. Jeremy asked Jonas to submit a PR for Gitian builds for OS X. https://github.com/namecoin/namecoin-core/issues/38#issuecomment-236101580 DrHaribo of BitMinter requested that getblocktemplate be re-added to Namecoin Core. https://github.com/namecoin/namecoin-core/issues/98 Jeremy points out that since nVersion=4 blocks are nearing the lock-in point, we should deal with this sooner rather than later so that BitMinter doesn't get kicked off the network. Brandon asked on GitHub about how wallet unlocking should be done with the name tab GUI. https://github.com/namecoin/namecoin-core/pull/67#issuecomment-240852324 Upon discussion, Brandon currently plans to try using the raw transaction API for this. Daniel submitted a PR to temporarily disable the low-S standardness check. This should improve confirmation times for the old 0.3.80 clients. The check will be restored after AAA activates. https://github.com/namecoin/namecoin-core/pull/100 Test reports would be great. Jeremy points out that this needs to be done before nVersion=4 blocks are locked in. Jeremy wonders whether we should cancel plans to release 0.12 as stable, and focus on 0.13 branch. Tentative plan: keep maintaining 0.12 until Bitcoin Core releases v0.13.0; backport the name tab to whatever stable branch exists at the time that it's merged to master. SPV Jeremy's initial PR for Namecoin support has been merged to libdohj. https://github.com/dogecoin/libdohj/pull/18 Jeremy still needs to rebase the bitcoinj-addons code based on the libdohj changes made during review, and then submit a pull request. In the meantime, Jeremy's latest bitcoinj-addons and libdohj code is posted. https://forum.namecoin.org/viewtopic.php?p=16788#p16788 Someone please test it? Jeremy asks if he should post a link on Reddit. Jonas says yes. Jeremy will do so. ncdns Jeremy asked about the old fork of a Conformal library (see previous meeting); Hugo doesn't recall details but thinks it had to do with pre-Namecoin-Core not following spec properly. Hugo would be happy to accept a PR to make it use the current Conformal libs. https://github.com/hlandau/ncdns/issues/12#issue-163964219 Jeremy pointed out that sometime in the future we should fix the Extended Key Usage Critical flag on the dehydrated cert template. Go's standard library doesn't have a built-in way of setting that flag, which is why it's not in the first draft. Jeremy and Ryan can't think of any plausible attacks where it matters. Jeremy suggests a 1.0 BTC bounty for an ncdns NSIS installer. Possibly funded 50/50 by NMDF and a fundraiser. https://forum.namecoin.org/viewtopic.php?f=18&t=2566 Mining Cassini noticed that BTCC and ViaBTC have started mining Namecoin. https://forum.namecoin.org/viewtopic.php?p=16703#p16703 This is good news for mining diversity. F2Pool's share of Namecoin blocks is down to circa 43% as of July 26, 2016. Public Relations Cassini represented us at GETD#4 in Berlin July 22-23. Jeremy mentions that we should think about translation workflow. https://github.com/namecoin/meta/issues/35 Jeremy notes that Bitcoin Core is using Transifex. https://github.com/namecoin/namecoin-core/blob/mastedoc/translation_process.md Jeremy says that whatever works for Bitcoin Core, should probably work for us. Midnightmagic concurs. Joseph believes that Armory (post-ATI) is trying Transifex. Brandon asks what the pricing looks like for Transifex. Joseph believes it's gratis for open-source projects. Jeremy notes that Wikipedia confirms this. Jeremy wonders what safeguards are in place on Transifex to reduce risk of malicious translations. Joseph isn't sure. Jeremy points out that the way we organize the list of exchanges doesn't make sense for decentralized exchanges like Bitsquare. https://github.com/namecoin/namecoin.org/issues/70 Jeremy suggests listing decentralized exchanges at the top of the list. Jeremy notes that this might annoy the centralized exchanges who pay us for placement, but that this doesn't bother him at all. Midnightmagic concurs. Pigeons mentions that he's seen an increase in Namecoin offers on Bitsquare recently. Jeremy will have a table at the OU CS welcome party on Sept. 9. Let's try to recruit some developers! Brandon asks what the status is of the students from last year. Jeremy is sad to report that the SPV student and the UX student from last year are not participating this semester. Pigeons says a "Namecoin vs Blockstack" FAQ entry would be helpful. Jeremy will work on it. Midnightmagic asks if a meetingbot would be welcome. Jeremy says yes. Midnightmagic will look at setting one up. Funding Jeremy has filed a complaint with Tip4Commit about their usage of CloudFlare CAPTCHAs. https://github.com/tip4commit/tip4commit/issues/300 Tip4Commit has not responded after 25 days. BountySource balance: $5/month from 1 recurring supporter Total funds available: $304 USD Pigeons suggests looking into Patreon. Jeremy notes that they have CloudFlare CAPTCHAs. Jeremy notes that Wikipedia says they take a 5% commision, which is half of BountySource's 10%. Jeremy notes that some free software projects use them currently. https://www.reddit.com/linux/comments/33dp6n/should_open_source_projects_use_patreonkickstartecqkrlkf Jeremy will look into this in more detail later. NMDF incoming funds: 0 mBTC received since 2016 07 03 0 NMC received since 2016 07 03 Pigeons suggests looking into Flattr. Jeremy notes that they have CloudFlare CAPTCHAs. Jeremy notes that Wikipedia says they take a 10% fee (same as BountySource). Jeremy will look into this in more detail later.Note: I made a typo in the title of this post on Reddit; the quoted date of the meeting is correct. (I can't see a way to edit the title of a Reddit post.)
checksum_of_previous block miners_pubkey value_you_scan_for_mining (each one gives a new checksum with a shot of beating the difficulty) accepted_transactions ... (whole list)The result of the checksum is the score, if you get a score below the current difficulty for a correct block. (Havent figured out how that is agreed on yet) You win the block, and may refer to it, to use it as money in your reward. A block is correct only if the transactions are also valid; i.e. dont send more than a wallet contains, all signatures must check out.(most transactions have signature, unless they're attached to the miner somehow)
#namecoin-meeting notes, 2016 05 15 # Present: Jeremy Jonas Joseph pigeons Housekeeping: Jeremy was away for the past week due to finals week. He's back now. As a result, this is a shorter meeting than last meeting. Namecoin Core Progress toward 0.12.0 milestone 7 tickets are closed, 5 remain open https://github.com/namecoin/namecoin-core/milestones/nc0.12.0 Windows Gitian builds Jeremy fixed Gitian Windows builds in master branch. OS X Gitian builds Jonas says that extracting the OS X SDK from Linux didn't seem to work; it produced a tar.gz that was very different in file size from the one produced on OS X. Jonas says it might be a good idea to just create the tar.gz deterministically on OS X and publish the hash. Jeremy is curious if the difference is innocuous. Do the content files have the same hash when extracted? Joseph suggests Debian's diffoscope tool. Jeremy says maybe ask Cory Fields from Bitcoin whether he knows anything about this, seeing as this topic is applicable to Bitcoin. Last week Jonas noted that Bitcoin Classic has a Gitian build for ARM, wondered if it would be useful for us. Jeremy checked; the commit was submitted to Bitcoin Core but was rejected due to poor code quality. https://github.com/bitcoin/bitcoin/pull/7659 So far no one has cleaned it up. 0.3.80 / Core compatibility johnc reports that 0.3.80 has trouble downloading blockchain from Core. https://forum.namecoin.org/viewtopic.php?f=7&t=2547 Jeremy wonders if this is something that we actually care about or need to fix. 0.3.80 is being hardforked off the network soon anyway. Jeremy doesn't see much reason to expend effort on making it easier to run 0.3.80. Jonas concurs that it's not a problem we need to fix Travis Builds Daniel fixed a Travis build issue relating to BIP 9. There's still at least 1 Travis build issue remaining. Regarding the wallet corruption issue that Jeremy brought up last meeting https://github.com/namecoin/namecoin-core/issues/89 The bug reporter confirms that Namecoin Core is not affected by the bug. Only Namecoin 0.3.80 is. Jeremy was able to help the reporter recover his wallet using the -salvagewallet option in Namecoin Core. Jonas mentions that someone is still mining on testnet with the old 0.3.80 client. This is annoying for people who are trying to sync the testnet. BitcoinJ Jeremy is still tinkering with BitcoinJ. Jeremy got an SPV name lookup to work. Not optimized at all yet; Jeremy has ideas for making it work better. Public Relations Jekyll site No NACKs received on Jekyll site, so Jeremy will push it to production as soon as possible. Downloads page Consensus on GitHub is to link to Namecoin Core binaries on the main downloads page. Full details at https://github.com/namecoin/namecoin.org/issues/57 . If anyone disagree with this course of action, say so on GitHub before we get around to filing a PR. Exchanges page Jeremy suggests adding Bitsquare https://github.com/namecoin/namecoin.org/issues/58 Jeremy notes that Kraken is delisting Namecoin soon. Jeremy considers this unsurprising; Kraken's AML policies caused most users to use ShapeShift or Bitsquare instead. We should remove Kraken from the Exchanges page. Funding BountySource balance: $5/month from 1 recurring supporter Total funds available: $164 USD
#namecoin-meeting notes, 2016 09 04 # Present: Jeremy Joseph Hugo Jonas Brandon Consensus Jeremy wrote up a draft proposal for a future consensus change: the "Soft Hard Name Fork". https://github.com/namecoin/meta/issues/38 Inspired by Luke-Jr's SegWit and AuxPoW forks. Would be great to have some people poke holes in it. Jonas suggests that testnet2 could be included when we fork away from 0.3.80. Jeremy probably wouldn't consider it a blocker, but probably wouldn't have any objection to including it. Namecoin Core Cassini has tested and ACKed Daniel's PR for disabling the low-S standardness check. Daniel has merged it. Daniel would like to release 0.13.0 based on Bitcoin Core 0.13.0, with the low-S standardness check disabled, and wait until 0.13.1 for the name tab GUI. https://forum.namecoin.org/viewtopic.php?f=8&t=2603 Jonas volunteers to do Gitian builds. Jonas ACKs releasing 0.13.0 without the name GUI. Brandon has added wallet unlocking to the name tab Qt PR. The raw transaction API turned out to be too complex for our timeframe. We'll look into adding it later. Also fixed all Travis CI failures in the PR. Also fixed the iCCP errors. Jeremy noticed a blocker bug that occurs when 2 people try to register a name at the same time. Brandon has pushed a fix, needs testing. Jeremy will try to test the fix. Jeremy asks if Jonas has had any luck submitting a PR for Gitian builds for OS X. https://github.com/namecoin/namecoin-core/issues/38#issuecomment-236101580 Jonas will try to submit a PR. TLS Jeremy notes that we need feedback on the dehydrated cert spec. https://github.com/ifa-wg/proposals/pull/24#issuecomment-232153966 Other clients Joseph mentions that there's an Electrum fork for Namecoin that seems dead. Jeremy notices there's more than one of them. After some confusion, Jeremy realizes that 2 of the Electrum forks are forked from each other. https://github.com/Kefkius/electrum-nmc-server https://github.com/Kefkius/electrum-nmc https://github.com/mazaclub/electrum-nmc-server https://github.com/mazaclub/electrum-nmc Joseph mentions https://jonasnick.github.io/blog/2015/05/09/fuzzing-bitcoin-consensus/ Joseph thinks it might be interesting to try with Namecoin clients. Public Relations The Google search result for namecoin.org is now fixed. Reminder that Jeremy will have a table at the OU CS welcome party on Sept. 9.
