IronSign

The project focuses on the issue of distributed signing of blockchain transactions for industrial use-cases. The goal is to create a prototype with a functional implementation of a signature protocol based on the methods of multi-party computation (MPC) and threshold signatures (TSS). The proposed system will support TSS generation and subsequent signing of transactions so that:

• the key is divided into N parts, stored on N independent devices, with each device knowing only its part,

• from these parts it is possible to cooperatively create one valid signature of a blockchain transaction,

• the process can be applied to as many blockchain platforms as possible, with a priority on Bitcoin and Ethereum and with the possibility of future expansion.
