Get this node's certificate

Returns the performance certificate this node issued for itself as a provider — a signed proof that its machine completed a known benchmark in a timekeeper-attested amount of time.

GET/certificate

curl https://<node>/certificate

A node that is not running as a provider has no certificate of its own and answers 404. A provider also answers 404 until its first benchmark run finishes — issuance happens in the background at startup, once the node has peers to gather timekeeper attestations from.

Field	Meaning
`provider`	Hex ed25519 public key of the provider the certificate belongs to.
`seed`	Hex benchmark seed, derived from the start attestation and the provider key.
`workload_version`	Version of the benchmark algorithm the proof was produced with.
`iterations`	Length of the benchmark hash chain.
`work_proof`	Hex final hash of the chain — the proof the work was done.
`score`	`1.0 / elapsed_seconds`, where elapsed is measured between the attested medians. Higher is faster.
`start_attestation_root`	Merkle root over the start attestations.
`end_attestation_root`	Merkle root over the end attestations.
`start_median`	Median attested start timestamp, in unix nanoseconds.
`end_median`	Median attested end timestamp, in unix nanoseconds.
`issued_at`	Equal to `start_median`.
`expires_at`	`issued_at` plus the validity period — 7 days.
`price_multiplier_milli`	Provider's price multiplier, ×1000 (`1000` = 1.000×).
`signature`	The provider's signature over the certificate.
`hash`	SHA-256 of the certificate's canonical bytes. This is the value a lease block pins in `certificate_hash`.

Certificates are compact by design: they carry merkle roots rather than the full attestation arrays.
