Problem Report
DB-Sync calculates wrong hash for the latest (HardForkInitiation) Governance action

Hash mismatch when fetching metadata from https://raw.githubusercontent.com/IntersectMBO/governance-actions/refs/heads/main/mainnet/2024-10-30-hf10/metadata.jsonld. Expected "8a1bd37caa6b914a8b569adb63a0f41d8f159c110dc5c8409118a3f087fffb43" but got "5e9460221d7cd7159abca1409b77364e4dc182d37a6c32b5843f969b185a3201".

But this is not the case

cardano-cli hash anchor-data --url https://raw.githubusercontent.com/IntersectMBO/governance-actions/refs/heads/main/mainnet/2024-10-30-hf10/metadata.jsonld

shows us 8a1bd37caa6b914a8b569adb63a0f41d8f159c110dc5c8409118a3f087fffb43 as expected

Sorry for the late reply. The problem here is that db-sync fetches a quite limited amount of bytes for DOS protection. So it hashes a trimmed version.

Hi @kderme, any update on when this might be resolved?

Does this affect only HardForkInitiation proposals?
