Summary

Proposal to upgrade the ckBTC index canister

Repository: https://github.com/dfinity/ic.git

Git hash: cf41372e3d4dc1accfe2c09a7969f8bddc729dc1

New compressed Wasm hash: dab6808d0dfc06e5e88336d0c3d3e45e5448c6e36c2a781f3e9e09bd450f528c

Upgrade args hash: 0fee102bd16b053022b69f2c65fd5e2f41d150ce9c214ac8731cfaf496ebda4e

Target canister: n5wcd-faaaa-aaaar-qaaea-cai

Previous ckBTC index proposal: https://dashboard.internetcomputer.org/proposal/140948

Motivation

The index canister's block-syncing timer is currently stuck, so the index no longer picks up new blocks from the ckBTC ledger. Upgrading the canister rearms the timer and resumes indexing. The proposed Wasm is identical to the one currently running, i.e. this proposal contains no code changes.
