Programmable Identities on Manta Atlantic
Manta Atlantic combines zkAddresses, zkSBTs, and selective disclosure keys to let builders compose identity systems that bridge on-chain compliance with user-centric privacy.
Core Building Blocks
- zkAddress pairs – Every participant controls a public Substrate account plus a shielded address for confidential asset and credential management.
- Prove Keys – Holders distribute verification keys to specific relying parties, enabling selective KYC disclosure without exposing global viewing access.
- Programmable schemas – Issuers encode logic for membership, accreditation, jurisdiction, or AML flags, then publish updates via runtime governance.
Identity Vault Pattern
- Bootstrap – Derive zkAddresses for each user and link them to public accounts through encrypted off-chain registries.
- Credential orchestration – Automate zkSBT issuance on approval events (KYC pass, accreditation, residency confirmation).
- Session management – Rotate Prove Keys per relying party and attach policy metadata (expiry, scope, revocation callbacks).
- Audit hooks – Stream anonymized issuance metrics to monitoring stacks for compliance reporting.
Cross-Chain Portability
- Atlantic credentials travel to other Polkadot parachains through XCMP, unlocking composability with DeFi venues such as Bifrost’s vMANTA staking derivatives.
- Identity payloads can also bridge to EVM ecosystems (e.g., Moonbeam, Ethereum) using Manta’s interoperability hubs, preserving privacy across domains.
Policy-Driven Verification
| Requirement | Implementation Strategy |
|---|---|
| Geographic access | Encode jurisdiction attributes inside credential schema and check using identity_verifyCredential, which wraps the zk verification flow described in the NPO compliance docs. |
| Transaction caps | Track credential usage counts off-chain and rotate Prove Keys when session budgets are exhausted. |
| AML monitoring | Subscribe to revocation events and apply business rules before processing settlement. |
Governance & Roadmap
- Manta Atlantic is scheduled for deprecation in July 2026; plan migrations to successor deployments while leveraging Atlantic for near-term compliance projects.
- Participation in staking/governance keeps credential issuers aligned with network updates that may alter identity pallet semantics.
