Identity Network

On-chain identity verification registries for the Sky ecosystem. See the docs.

Contracts

• IIdentityNetwork - Shared interface exposing isMember(address) -> bool.
• IdentityNetwork - Holds both a direct member set and a list of child subnets. isMember checks direct members first, then loops all registered subnets. Buds manage members and subnets. Wards manage auth and bud access.
• IdentityFactory - Deploys networks with initial admin, buds, members, and subnets in one call.

Access Control

Two-tier auth model following MakerDAO conventions:

Role	Set by	Can do
Wards (rely/deny)	Other wards	Manage wards and buds
Buds (kiss/diss)	Wards	Add/remove members and subnets

Membership Resolution

isMember(usr) traverses the tree — direct members first, then each subnet recursively:

isMember(0xABC)
  │
  ├─ 0xABC in directMembers?  ──► yes → return true
  │
  └─ for each subnet:
       subnet.isMember(0xABC)?  ──► yes → return true
                                        (subnet checks its own
                                         directMembers + subnets)
  return false

Subnets are themselves IIdentityNetwork contracts, so networks compose into trees.
