2026-09-26: not on the chain yet.
29,933,985 rows of DEBYKO's history of 2026-09-26 UTC, in 9 tables, under one root.
The anchor proves the data did not change after the anchor time; it proves nothing about its correctness at collection. Nothing of this day is on the chain yet: the root below is DEBYKO's own until it is posted, and a proof of one of its rows answers ANCHOR_NOT_YET.
The 9 tables under the root.
Each table's rows of the day form one Merkle tree (RFC 6962); each tree's root, with its table, day, row count and schema version, is one leaf of the day's tree, in table-name order. Chunks are the 4,096-row pieces a proof is read from.

Check this day without trusting DEBYKO.
The same steps as docs.debyko.com/attest/verify, with this day's values filled in. The first asks the chain alone; the others prove one row of the day under the root it returns. Any public Base RPC does in place of https://mainnet.base.org.
The root on the chain
roots(uint32) of the contract, with the key 20260926. With Foundry, or with curl alone; the answer is the root, 0x41808b611c…e7a8c5.

The day's root and its partitions from the API, without a key: it must be the root the chain returned.
curl -s https://api.debyko.com/v2/anchors/2026-09-26The proof of one row
Any stored row of the day, by its listing, layer and own time. Proofs need no account and no key (30 a minute and 2,000 a day from one address). This one is BTCUSDT's 12:00 trade candle on BINANCE-USDM.

verify.py from github.com/debyko/verify (one file, the standard library only, MIT) hashes the row, walks both paths and reads the root from the contract: ✓ valid, or ✗ and the step that failed.
