Post-quantum security firm Project Eleven has executed the acquisition of blockchain cryptography developer Riva Labs. The acquisition consolidates specialized engineering talent and intellectual property across hash-based post-quantum signatures, post-quantum Multi-Party Computation (MPC), account abstraction protocols, and hardware signing implementations across Ethereum and primary Layer-1 public blockchain ecosystems.
The transaction addresses critical migration vulnerabilities facing public ledger architectures, where public-key cryptography—predominantly Elliptic Curve Digital Signature Algorithm (ECDSA) and Schnorr signatures—remains susceptible to Shor’s algorithm running on fault-tolerant quantum computers. Rather than applying isolated algorithmic patches at the signature layer, the combined engineering pipeline integrates post-quantum primitives directly across the full technology stack, linking key management, smart-contract wallet infrastructure, and protocol-level consensus rules.
| [ Project Eleven / Riva Labs Integrated Post-Quantum Stack ] | ||
|---|---|---|
| Infrastructure Layer | Core Technology & Cryptographic Primitives | Engineering & Protocol Objectives |
| • Signatures & Key Auth | • Hash-based post-quantum signature schemes • Consumer hardware signing execution | • Replacing vulnerable ECDSA/Schnorr keys while maintaining real-time transaction throughput |
| • Custody & Key Mgmt | • Post-quantum Multi-Party Computation (MPC) • Account Abstraction (ERC-4337 evolution) | • Distributing secret shares via quantum-resistant MPC without single points of failure |
| • Cryptanalytic Testing | • AI-assisted automated cryptanalysis • Crypto-agile software architecture | • Accelerating real-time vulnerability testing and algorithm swap capability |
A key focus of the acquisition is the integration of AI-driven research methodology developed by Riva Labs. By deploying automated artificial intelligence tools to accelerate cryptographic research, cryptanalysis, and code validation, the team aims to build agile post-quantum migration frameworks capable of adapting as NIST-standardized lattice and hash-based algorithms evolve. The merged research group will focus on deploying practical, low-overhead post-quantum signing routines on consumer-grade hardware to ensure backward compatibility and operational scalability across decentralized networks.
