This list uses one of the several proposals for CHIPs structure and classification. The discussion is currently ongoing. In no way it represents a final decision or imposed measure. When the community reaches an agreement, the classification of this list can be easily altered.
The classification in use here follows BIP 0002 and BIP 0123 proposition.

You missed this one: Multiple OP_RETURNS - This time for real! - #12 by proteusguy

Added. Thanks for the heads-up.

If we ever adapt BIP123 into a “CHIP123”, it would probably be good to insert a “Relay Policy” layer between “Consensus” and “Peer Services”. It would contain things that can’t split the chain (unlike “Consensus”) but can cause consistency/security issues for 0-conf (unlike what one might expect for “Peer Services”). But for now “Peer Services” is the best fitting category to put these CHIPs in.

If you draft/propose such a CHIP for Relay Policy Layer I will support it :grinning:.

I have updated the multiple OP_RETURN CHIP to “Proposed” status.

Thanks for maintaining a list!

The PMv3 proposal is now a CHIP here. I don’t think I’m able to edit the title of this thread, but could an admin change it to follow the format of other threads about CHIPs? Maybe CHIP-2021-01-PMv3: Version 3 Transaction Format + the CHIPs tag.

Thanks for the information.
Both, CHIPs list and tittle of the correspondent post, updated.

I just created a thread for a new CHIP here:

Targeted Virtual Machine Limits CHIP added to the list.

I am very impressed with the content I see here.

Shouldn’t the CHIP for Multiple OP_RETURNs and Unconfirmed Transaction Chain Limit be something like implemented or being implemented? It will be a few hours left before the May 2021 Upgrade goes live and said CHIPs are activated.

Let’s wait for those CHIPs owner’s confirmation.
