On-chain record

Every day at 00:10 UTC, the paper records of the previous day are hashed into one Merkle root and published on Solana as a memo. Any signal can be checked against it, here or with the scripts, without trusting this site.

Verify a signal

    The browser recomputes the leaf hash and the root with WebCrypto, then reads the memo transaction straight from a public Solana RPC. Scripts: verify.mjs · verify.py.
