 a normal permissioned blockchain is developed and managed by one group. this group governs everything, and decides who can join and leave etc. What i am looking for is a way for a closed blockchain such as this, to be governed by a more decentralised group. This means development is spread across participants, and decisions are voted on by many participants through rules/protocols encoded within the blockchain itself (similar to on-chain governance).
