Arachnid’s, Micah’s, CreateX … not even mentioning my own that I presented in DevCon Osaka … and now this. When are we doing to deploy permissionless create2 factories? The point is to have one, not fifteen!

IT IS TIME TO KILL THE PRIVATE KEY. Safe Research just dropped ERC-7955: a permissionless CREATE2 factory that lets anyone deploy deterministic contracts across chains, no special keys, no GitHub issues, no waiting for team approvals. 👇👇.

Sometimes my 2 years old kid feels like a poorly coded for loop:. « 1, 2, 3, 4, 8, 9, 10, 11, 12, 13, 14, 12, 12, 13, 14 ».

And the biggest DON’T:. Don’t take your existing product interface, write its documentation following the ERC format, push it to final without discussion, and they say your product follows a standard.

ERCs DONT:.- be afraid to stay in draft.- assume your vision of the problem is objective and exhaustive.- assume you’ll figure out everything alone.- think that a good specs written by a good author will necessarily get adopted.- think that a spec that isn’t adopted has value.

ERCs DO:.- draft in public.- have more than one author from more than one project (standardization is a team game).- spend more effort trying to reach out to devs (to get feedback and contributions) than trying to finalize the document on your own. 1/2.

Guys, ERCs are first draft for a reason. You're not supposed to privately draft the draft and then release it when nobody can give you feedback anymore.

How are supposed not to make fun of chemists when they make these kind of statements? This is just making the (imo bad) point that physics is a superior science compared to chemistry!. (Please tell me what element a neutron star is made of).

Is it me, or are LZ77 implementations different? Like they all use different encoding, and data that is compressed with one library cannot be decompressed with another?. How did we come to it?. Can’t there be a clear and standard dictionary-based, easy to decompress, format?.

If this is real, it is probably the best example of “how to destroy years of amazing brand image in just one tweet”. 99% of software projects do not need a token to work. And they shouldn’t have one. @gitcoin and @dripsnetwork are the way to go !.
