We're a bunch of researchers and have simply ready a draft addressing a niche in cryptographic custody for autonomous brokers.
The issue: brokers executing autonomously want key custody, however are the least reliable entities to carry keys alone.
Present options (sizzling wallets, good accounts, TEEs, normal MPC) have elementary gaps when utilized to autonomous signing.
Our strategy: threshold ECDSA (CGGMP24, 2-of-3) with coverage enforcement between distributed signing events — the server occasion evaluates constraints earlier than collaborating within the interactive protocol. The total non-public key by no means exists.
We're at the moment searching for skilled suggestions earlier than publication, notably on:
– Risk mannequin protection (particularly colluding events)
– Coverage enforcement mechanism soundness
– Sensible deployment situations
f you’re employed on distributed cryptography, MPC protocols, or threshold signatures, we'd worth your technical perspective.
