We’ve published our draft of the ICRC-77 Standard for ICRC-72 replays. This allows your canister to recover from messages that it may have missed while upgrading or being off-line. ICRC-72 Extension - ICRC-77 Event Message Replay Interface · Issue #77 · dfinity/ICRC · GitHub
We’ve also turned the demo back on and you can join Alpha 2 by sending 0.01 or more ICP through the dapp at https://iedms-tqaaa-aaaal-amieq-cai.icp0.io/.
All the users from Alpha 1 have been archived, so no need to rejoin unless you just want to try out the tech.
The new alpha doesn’t scan every trx and only broadcasts on demand after doing an ICRC-2 TransferFrom. We’ll get back to ledger scanning soon, but we wanted something up so you could browse the dapp we are building for network topography and introspection. You can find that here: ICP + Vite + React
Let us know if you have need of pub/sub and would like to be an alpha tester.
