Explore the AlgoVoi settlement attestation format, a reference implementation for multi-chain categorical attestations using RFC 8785 canonicalisation.
The AlgoVoi settlement attestation package provides a reference implementation for a specific data format designed to bridge the lifecycle between admission, settlement, and refund processes [1]. This framework, authored by AlgoVoi, is based on the IETF Internet-Draft draft-hopley-x402-settlement-attestation-00 and utilizes the JCS RFC 8785 canonicalisation discipline to ensure byte-deterministic verification across different blockchain environments [1].
Key takeaways
The settlement attestation is structured as an eight-field JSON object [1]. To maintain consistency across different systems, the format relies on the algovoi-substrate package for the JCS canonicalisation primitive [1]. When an attestation is emitted, it includes an in-band "pin" that identifies the canonicalisation rule applied, specifically canon_version: jcs-rfc8785-v1 [1]. This pin allows downstream verifiers, such as the algovoi-audit-verifier or other conformant third-party tools, to correctly interpret and validate the data [1].
The reference implementation supports production operations across eight chain families, utilizing specific reference vectors and invariants to maintain data integrity [1]. By anchoring admission, settlement, and refund receipts to the same canonicalisation discipline, the system allows a verifier to walk the entire audit chain and confirm the status of a payment under a single, verifiable pin [1].
The AlgoVoi settlement attestation framework serves as a mechanism for standardizing how multi-chain categorical attestations are handled and verified [1]. By providing a reference implementation under the Apache 2.0 license, AlgoVoi enables developers to integrate these receipt formats into their own systems while maintaining compatibility with the Substrate Adopters Registry [1]. This registry acts as a neutral space for documenting adopters who anchor their specifications to the jcs-rfc8785-v1 discipline, ensuring that as the ecosystem grows, third-party verifiers can continue to validate these artefacts against established canonical bytes [1].

The native cryptocurrency of the Algorand blockchain is called ALGO.
Algorand uses a Byzantine agreement protocol that leverages proof of stake and cryptographic sortition to randomly select committees of users to propose and certify blocks.
Algorand has implemented Falcon signatures to safeguard its chain history and executed the first quantum-resistant transaction on its mainnet in 2025.
As of March 17, 2026, the SEC and CFTC have jointly identified ALGO as a digital commodity.
