On-chain stake pool operator to delegates communication

Developers CIPs
1

Hello,

With the recent changes around the k parameters, the communication between stake pool owners and their delegates is again on the table. I have opened a pull request for CIP for a standard build on top of the transaction metadata feature. This is supposed to be the on-chain communication as an alternative to off-chain communication provided by tools and blogs.

Looking forward to the collaboration and comments on this CIP.

Hey there,

lgtm on a first view. One question That came to mind is why have the content property be an array of 64 bytes instead of just a string bounded to the 64kb overall size? Are there technical aspects here?

Yes, sadly this is the limitation of the current ledger - 64 bytes per key, the whole metadata might be up to 16kb.
