Do Cardano's governance vote rationales still resolve? Measuring it with db-sync and a blake2b-256 check
Under CIP-1694, a Cardano governance vote can carry an anchor : a URL to a document that explains the vote, plus a blake2b-256 hash of that document. The hash goes on-chain and stays there. The document does not. It lives on someone's IPFS gateway or GitHub repo, and nothing in the protocol keeps it there. That turns a vague question into one you can measure: is Cardano's governance record…
In Cardano's governance system, votes can include an anchor, which is a URL to a document explaining the vote, along with a hash of that document. This hash is stored on the blockchain, ensuring its durability. The question of whether these anchor documents remain accessible and unchanged over time is measurable. This article explains how to assess the durability of Cardano's governance records using db-sync's Postgres database and a custom fetcher, while addressing potential pitfalls in the process.
