Receipt - Parmana

Receipt answers: what’s the portable proof of trust? A Receipt is a signed, cryptographic attestation generated after a Business Transaction’s execution has been successfully verified. It’s the artifact you’d hand to an external auditor or regulator as portable proof — it doesn’t require them to trust your infrastructure, only the signature.

Fields

Field	Type	Description
`receiptId`	`string`	Unique identifier for the receipt.
`businessTransactionId`	`string`	The transaction this receipt attests to.
`trustRecordHash`	`string`	Hash of the Execution Trust Record at receipt time.
`receiptHash`	`string`	Hash of the receipt itself.
`issuedAt`	`Date`	When the receipt was issued.
`algorithm`	`string`	The signing algorithm used.
`signature`	`string`	The cryptographic signature.

Generating a receipt

const receipt = await client.receipt(businessTransactionId);

Receipt generation is handled by the crypto package. See Architecture → Security Model for the cryptographic guarantees this rests on.
