LEZ Multi-owner Accounts §

Resources Required §

• 1 Researcher
• 1 Engineer

Risks §

• Supporting multiple owners must not leak the membership or size of the owner set
• Authorization scheme must keep circuit changes minimal to avoid proving-time regressions

Deliverables §

Multi-owner Private Accounts §

Owner: David Rusu

Feature: FURPS

Allow a single private account to be owned by multiple users, enabling shared accounts where spends require authorization from the owner set. Authorization is expressed through multi-signatures so that group ownership is supported with minimal changes to the existing account circuits.

Checklist:

• Multi-owner ownership approaches documented
• Multi-signature authorization spec
• Multi-owner account implementation
