Transparency log
Signed tree heads, verifiable by anyone.
Every hour the chain-master KMS key signs the current tree head for each active segment. The signed head, the public key, and a consistency proof to the previous head are downloadable from this page. Run verify.sh locally to confirm any STH against the master public key.
Master public key
ECDSA · NIST P-256 · SHA-256
