What hashsigs-solidity does

This project brings post-quantum hash-based signature verification to the EVM (Ethereum Virtual Machine). It provides Solidity contracts for verifying WOTS+ and SHRinCS signatures on-chain. This allows smart contracts to authenticate transactions or data using quantum-resistant cryptographic schemes, providing an upgrade path for long-term secure Ethereum applications.

Ethereum and EVM smart contract developers focused on high security, future-proofing, and post-quantum cryptography.

  • EVM Compatibility: Native Solidity implementations for Ethereum and compatible chains.
  • WOTS+ Verification: On-chain verification of Winternitz One-Time Signatures.
  • SHRinCS Verification: On-chain verification for SHRinCS signatures.
  • Gas Optimization: Tailored for efficient execution within the EVM constraints.
  • Post-Quantum Ready: Enables smart contracts to rely on quantum-resistant proofs.

Where teams use it

Quantum-Resistant Wallets

Building EVM smart contract wallets that cannot be compromised by quantum computers.

Long-Term Archival Security

Securing on-chain data and state transitions for decades into the future.

Cross-Chain Bridges

Authenticating messages across networks with future-proof security assumptions.

Secure Governance

Ensuring DAO voting mechanisms remain secure against quantum adversaries.

Getting started: forge test

README

main branch

WOTS+ Solidity Implementation

A Solidity implementation of the Winternitz One-Time Signature Plus (WOTS+) scheme.

Development

This project uses both Hardhat and Foundry for development and testing.

Prerequisites

  1. Install Foundry:
curl -L https://foundry.paradigm.xyz | bash
foundryup
  1. Install Node.js dependencies:
npm install

Testing

Run the Foundry tests:

forge test -vv

The -vv flag increases verbosity to show more test details. Use -vvv for even more detailed output including stack traces.

Building

forge build
