[Research] Guardian: Function-Gated MPC Wallets for AI Brokers

We're a gaggle 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 (scorching wallets, sensible accounts, TEEs, commonplace MPC) have basic gaps when utilized to autonomous signing.

Our method: threshold ECDSA (CGGMP24, 2-of-3) with coverage enforcement between distributed signing events — the server occasion evaluates constraints earlier than taking part within the interactive protocol. The complete personal key by no means exists.

We're at the moment searching for professional suggestions earlier than publication, notably on:

– Risk mannequin protection (particularly colluding events)

– Coverage enforcement mechanism soundness

– Sensible deployment eventualities

f you’re employed on distributed cryptography, MPC protocols, or threshold signatures, we'd worth your technical perspective.
