arc_getCertificate

POST
/{apiKey}
CUs20

Returns the Malachite BFT commit certificate for a finalized block on Arc. The certificate contains the consensus round, the finalized block hash, and the base64-encoded validator signatures that decided the block. It is produced by Arc's Malachite consensus layer and is only available for blocks that have already been finalized.

Because Arc has deterministic finality on inclusion, once a certificate exists for a given height it is immutable and safe to cache indefinitely.

See the Arc node RPC reference for background on the arc namespace.
