MPC-BLS Protocols

We created the Safeheron Cryptography Basic Algorithm Library suite in C++ to make it easier to develop upper-layer cryptographic protocols, which includes the Big Number Computation Library, the Abstract Elliptic Curve Algorithm Library, the Homomorphic Encryption Algorithm Library, the Secret Sharing Scheme Algorithm Library, and the Zero-Knowledge Proof Protocol Algorithm Library.

TSS-RSA is a threshold signature algorithm for RSA that we've implemented. It has capabilities for generating key shards, signing by distributed keys, verifying signature shards, combining and verifying shards' signatures. To propel the algorithm's use cases in the Arweave ecosystem, we have been actively collaborating with the project’s developers.

GitHub

Safeheron has collaborated with MetaMask and Keystone to implement a two-party MPC wallet POC between MetaMask Snap and Keystone. The POC demonstrates functions such as distributed key generation, distributed signing, transfer of assets, backup & import of key shards.

MPC theory-based {t, n}-threshold Ed25519 signing protocols which are implemented in C++.

To be open source

It allows for a group of MPC private key shards to be used for managing multiple wallets and supports multi-party private key derivation, i.e. the derivation of sub-private key shards and corresponding public keys from a private key shard group in accordance with BIP44. Currently, there's support for MPC-ECDSA, MPC-Ed25519, and MPC-BLS protocol derivation algorithms.

To be open source

They support two-party protocols for HMAC-SHA256, HMAC-SHA384, and HMAC-SHA512, as well as key shard generation, distributed key refresh, and distributed signatures.

To be open source

Based on zero-knowledge proof, the private key is encrypted, and without the attainment of the plaintext, it verifies whether the ciphertext is the encryption result of the specific private key.

To be open source

Policy approval processes are executed in accordance with the user's predefined policies and approval actions in TEE (Trusted Execution Environment).

To be open source

MPC theory-based {t, n}-threshold BLS signing protocols which are implemented in C++.
