[Spec v4] General Impl Guidelines

[mjfelis]

General Recommendations

• General info regarding authority, authorizations, operators, etc: https://verana-labs.github.io/verifiable-trust-vpr-spec/index-v4.html#authorization-and-fee-grants
• some attributes have been removed. Make sure to recheck all attributes in all messages. Example: removed country, slashed_by, modified_by ... from permission
• check the data model, there are some changes, more particulary to the way we are handling PermissionSessions.
• permission overlap control has been added to all methods that can modify permission state. The idea is to have only one active permission at a time (for the same schema, type (role), validator_perm_id).
• do not take into account SchemaAuthorizationPolicy stuff, this will be moved to spec v5.
• remove support for DID Directory, it is not needed anymore
• some methods have been removed, like reclaim trust deposit (deposit is not claimable anymore)
• trust deposit has been removed for trust registry and credential schema creation.
• query methods have not been updated yet, I'm on it. Some are missing.

Development cycle and deliveries

• All development delivery of 0.10.x must be done on Devnet only
• Devnet state can be reset at any time, when needed. Do not lose time doing data migration.
• When spec v4 has been fully implemented and tested in devnet (with indexer, frontend, etc) then testnet state will be reset, too, and a new testnet will be launched with v0.10.x. We have until maximum 15/04/2026 to deliver the new Testnet based on spec v4.
