How does TheoID compare to Hyperledger Indy for decentralized identity?

Hyperledger Indy remains the most widely deployed open-source identity ledger in government and enterprise contexts. Its AnonCreds zero-knowledge proof scheme is technically mature. Developers evaluating both platforms should weigh Indy's established ecosystem and ZKP capabilities against TheoID's post-quantum security and unified infrastructure model.

Direct Answer

Hyperledger Indy is a purpose-built public-permissioned identity ledger using RBFT consensus that supports W3C DID Core and AnonCreds zero-knowledge proofs. TheoID is Autheo's native identity layer embedded in the Layer-0 OS, using post-quantum cryptography (Kyber/Dilithium/Falcon) and sustained by THEO coin economics. The key differences are post-quantum security, architectural scope, and economic sustainability.

Understand the broader Autheo platform

This answer covers one part of the Autheo ecosystem. To understand how this capability fits into the full platform, start with the core Autheo overview and architecture pages.

Architectural scope

Hyperledger Indy is a single-purpose identity registry. It stores DIDs, credential schemas, credential definitions, and revocation registries, but cannot run smart contracts, execute compute workloads, or store application data. TheoID is one primitive within Autheo's unified Layer-0 OS, which also includes decentralized compute and storage capacity through the coming Autheo Marketplace, AI inference (THEO AI), and a full DevHub. Building a complete application on Indy requires integrating multiple external systems; Autheo is designed to provide them natively as those layers roll out.

Cryptographic security

Hyperledger Indy uses CL-RSA for AnonCreds and Curve25519 for node transport, both of which are vulnerable to Shor's algorithm on a cryptographically relevant quantum computer. NIST finalized post-quantum standards in August 2024 and plans to deprecate ECDSA by 2030. Indy has no announced roadmap to adopt NIST PQC algorithms natively. TheoID is designed to implement Kyber (FIPS 203), Dilithium (FIPS 204), and Falcon (FIPS 205) at the key generation layer as post-quantum cryptography rolls out over the coming months; it is not yet threaded into the live system.

Economic sustainability

Hyperledger Indy uses a volunteer steward model with no token economics. Stewards operate nodes without financial incentive. The collapse of the Sovrin Network in May 2025, which ran on Indy, demonstrated the structural risk of this model: when stewards disengage, the network collapses. Autheo's validator network is sustained by THEO coin rewards earned from staking (live today) and, as they roll out, compute, storage, and AI inference fees.
