What the first ten confirmations found
Ten of the archive's 37 coins now carry a confirmed source repository. That is the whole of what changed today: a record of which coins have a project on GitHub that names them and describes itself as a cryptocurrency, checked against its own words instead of a name match alone. It says nothing about whether any of these coins are still alive.
The ten span a wide range of last activity. Tattoocoin's repository was created and last pushed to on the same two days in May 2014. Flavorcoin's repository dates from October 2015. Bunnycoin, LiteBitcoin and WomenCoin each carry a handful of commits through 2018 and 2019 and then stop. InflationCoin and Infocoin run a little later, into 2019 and 2020. Zennies runs to December 2021. SocialSend's repository, with 33 stars, was still being pushed to as recently as April 2022. Pepecoin is the outlier: its repository was created in 2023 and, as of this week, is still receiving commits, with 182 stars behind it. The code that says it belongs to these ten coins did not all stop at the same time, and one of the ten has not stopped.
None of this says whether a chain is producing blocks. A repository going quiet in 2018 says a project stopped committing code. It does not say a network stopped confirming transactions, and the reverse holds too: a chain can keep running long after its code stops changing. That distinction is stated on every confirmed entry, because a repository finding and a chain finding are different claims and this archive keeps them apart.
Three more candidates were checked and did not confirm. One, for InsaneCoin, turned out to be a stand-alone paper-wallet generator that mentions the coin's ticker without being its project. One, for Piecoin, describes itself only as "my cryptocurrency" and never names the coin. One, for Scorecoin, returned no qualifying sentence either way. All three stay unverified, and the evidence checked against each one is recorded here rather than left out.
The remaining 24 coins have no confirmed repository yet, mostly because no high-confidence candidate has turned up for them at all. That gap is the current state of the archive.
