Paste a deed transaction hash to view its SCP Finality Certificate
“Settlement is not a promise.
It is a mathematical proof.”
SCP Finality Certificates are cryptographic proofs that a deed transaction was committed by 3 of 4 SWSS Chain validators. Once issued, the certificate is immutable — it constitutes legal-grade evidence of settlement that any counterparty, court, or regulator can independently verify from the public chain.
Certificate Properties
Issued per deed transaction
Every type 0x03 or 0x04 transaction receives a SCP Finality Certificate at block commit. The cert root hash is embedded in the block ExtraData field.
Signed by 4 validators
The certificate is covered by the BFT proposer signature — confirmed by 3 of 4 active validators before the block is committed. No single party can forge a certificate.
Immutable and retrievable
Finality certificates are persisted to disk and survive node restarts. Any party can retrieve a cert via swss_getFinalityCert(txHash) at any time after settlement.
