Hi all, 

It looks like there are only a few mailing lists left on
https://lists.linuxfoundation.org/mailman/listinfo and all of the
remaining ones are using Mailman version 2.1.15, which is not the
current version - https://www.gnu.org/software/mailman/   

Was there any decision made on where to move the bitcoin-dev mailing
list to? 

Thanks, 

Brad

Or, the commitment to all of that could be just included "every sometimes" to the existing Signet chain, because it would take no additional on-chain bytes, and can be easily done in the coinbase transaction.

Even better: because of "master public keys", the regular participants could be allowed anyway, without providing additional Proof of Work. Their signature would be sufficient in that case.

Of course, it is not mandatory to accept commitments at all, which means, they could be easily disabled, if they would be misused. Or we could start with no commitments, and introduce them later if needed.
> 9. Because Signet challenge can contain some multisig, or even some Taproot address, there will be no issue with using the same password to access the moderation panel. Also, in that case, it is possible to prove later, which moderator accepted which message. And also, it is still possible to use some shared key, if revealing that is not desirable, or even it is possible to easily reach "approved by all moderators" messages, because their Schnorr signatures could be combined. Also, any K-of-N multisig can be battle-tested in that way.

I guess we can try some existing chains first, and if there is no promising altcoin, or if we don't want to be associated with any altcoin, then our own Signet-like network could solve it.
