Glass Hull · certificate verifier

Enter a certificate id. The page shows the frozen method hash, the block range and the entity registry, then re-derives the headline number live against the RPC you supply. No login, no tracking, nothing is sent anywhere except JSON-RPC calls from your browser to the RPC you choose.

Certificate id RPC endpoint — paste any Robinhood Chain 4663 JSON-RPC URL you trust. Default = the public RPC through this site's read-only relay (the public RPC's own CORS header is malformed, so browsers cannot call it directly); /verify/rpc?upstream=node = the Glass Hull archive node.
