I have seen this referenced as some sort of official account for EOS mainnet related repositories:
- Is it actually official?
- How do we know if this is official since this is not block.one?
It is official.
See the link below.
This article was written by EOS New York. EOS New York is the top 21 Block Producer on the EOS Mainnet Blockchain.
I asked EOS New York about this content via Twitter. EOS New York responded as follows.
Block on isn't official anymore. The EOS Mainnet repo is.
