Building the next generation of multisignature custody tools for digital assets Bitcoin. With Flexible Round Optimized Threshold (FROST) signatures, you can share custody of bitcoin with some t-of-n threshold:
For example, you could arrange a 2-of-3 where one device is your phone, one is your laptop, and the third is a hardware wallet. In order to spend your bitcoin you must sign on two of these three devices. An alternative scenario that a company with 6 exectutives generates a FROST key which they share, requiring 4-of-6 to sign for the company.
Unlike existing multisignature technology (script multisigs), FROST retains upmost privacy. Recently we have added FROST to the secp256kfun library. I am also tinkering with a work in progress ROAST wrapper to make these multisignatures robust, guaranteeing signatures with t-of-n honest signers.
