Checkpoint seq 2

anchorconfirmed · solana mainnet

The seal for the UTC period beginning 2026-08-10. The whole package — body, signature, and commitment — is published at /ledger/checkpoints/2.json, and it verifies against the key on the trust anchor page with no network and no chain.

The anchor

This checkpoint’s commitment is carried in the memo of a confirmed Solana mainnet transaction, so the seal is externally witnessed: an independent record that this commitment existed by that block, held by a party with no stake in ours.

witness

The chain witnesses a commitment and nothing more. It does not read the ledger, re-run any work, or examine a signature — a transaction proves when a string was published, never that the work behind it was done correctly. The proof of that is the ML-DSA signature over the body, checked against the published key.

Neighbours

A checkpoint’s prev_link is what makes the chain a chain: seals are read in order, and a gap is a question, not a rounding error.
