Problem statement

https://en.wikipedia.org/wiki/Secure_multi-party_computation https://github.com/binance-chain/tss-lib

The current implementation of TSS/MPC lack scalability and have an upper bound for the subset of nodes that can be included in an MPC without loosing in speed:

• In the production environment current most used TSS/MPC library binance TSS can support 20-30 nodes
  • This limit decentralization possibility of a protocols building on top of that solution
• There were several attempts to improve this situation

  • Frost implementation(https://blog.coinbase.com/frost-flexible-round-optimized-schnorr-threshold-signatures-b2e950164ee1)

but none of them proved to be time tested and none have formal crypto verification

The task

1. Do research on current proposals for scaling improvements

• a SWOT analysis of a current solution
• a cryptoanalysis on proposed solutions
• Identify good and bad patterns of a cryptographic primitives that usually used is a such protocol

2. Propose or select an algorithm that can be used to scale a TSS/MPC setup

• Propose an argument and formal verification why this setup

3. Implement a Proof of Concept of this algorithm with any approved languages (Rust/GO)
