BNB Attestation Service
About
BNB Attestation Service is a decentralized infrastructure protocol built on the BNB Chain ecosystem to facilitate the creation, verification, and management of digital attestations. The protocol allows users, decentralized applications, and enterprise entities to issue signed assertions regarding identity, compliance, credentials, and real-world asset provenance. Operating across BNB Smart Chain, opBNB, and BNB Greenfield, the service provides standardized schema registries, cryptographic signature verification, and decentralized storage integration. Developers integrate the framework to enable trustless credential verification, reputation scoring, permissioned access control, and verifiable audit trails for decentralized finance, gaming, and governance applications.
Snapshot
Operations
Products and/or services of BNB Attestation Service
- Attestation Schema Registry: Smart contract registry for defining, publishing, and standardizing structured attestation data formats. Developers register custom schemas with specified data types, enabling interoperable credential issuance and automated verification across smart contracts on primary layer-1 and layer-2 networks.
- On-Chain Attestation Issuance: Infrastructure for creating and submitting cryptographically signed attestations directly to blockchain ledger smart contracts. On-chain attestations provide immutable, publicly verifiable proofs for decentralized identity verification, governance voting rights, credit scoring, and protocol compliance workflows.
- Off-Chain Attestation Framework: Tooling for generating and validating cryptographically signed off-chain credentials using standard cryptographic signatures. Off-chain attestations reduce transaction costs and latency while storing structured credential payloads off-chain and verifying them on-demand via cryptographic signature proofs.
- Greenfield Storage Integration: Decentralized data availability and storage pipeline integrated with decentralized cloud networks. Large credential files, identity documents, and high-volume attestation metadata are permanently anchored to decentralized storage buckets with fine-grained access control policies and cryptographic hashes.
- Attestation Indexer and API: Data indexing infrastructure and GraphQL API endpoints for querying attestation data across supported network layers. The indexing service retrieves schema definitions, issuer records, recipient histories, and revocation statuses to power real-time application user interfaces.
- SDK and Developer Tooling: Software development kits and contract libraries available in JavaScript, TypeScript, and Solidity. The suite simplifies schema registration, message signing, payload encoding, cryptographic validation, and contract integration for decentralized application developers building trust architecture.
