Latest public-ledger days

GET /v1/ledger-days

https://verify.tanba-ooh.kz/v1/ledger-days

The newest 30 days, newest first. For each anchored day the platform computes a Merkle root over the approvals issued and revoked that day and a digest, SHA-256 of the anchor body hash followed by the root, and has the digest timestamped in Bitcoin through OpenTimestamps. status is pending until a Bitcoin block attestation is in the proof, then pending_check until the platform has compared the value the proof commits to with the merkle root in the header of that block, read from two independent block explorers, and anchored with block_height only after that comparison succeeded. Served on the verify and app hosts, cached for 60 seconds.
