Ribose Consensus Protocol
Ribose is a Delegated Proof of Stake (DPoS) consensus protocol. GeneChain uses Ribose to reach network consensus and avoid forking.
Note: This topic is still under construction.
Ribose selects 21 validation nodes to produce blocks in turn.
Anyone can sign up for an account as a validator by calling register method of the system contract, and only the validator account can accept mortgage in the system contract and run for active validators.
Anyone can increase the mortgage weight for any invalidator by staking their RNA and ARM or one of them at any time. For the weight algorithm, see Mortgage Weight Algorithm. Users can also withdraw their mortgage to get their RNA and ARM back. However, the mortgage needs a lockup period to stabilize the network. It is tentatively set as 86,400 blocks, which is about 72 hours.
The system contract will record the top 50 validators with total mortgage weight as candidate validators. To ensure that the candidate validator remains active, a validator can be included in the candidate list only when its total mortgage weight changes. Hence, when a validator is removed from the candidate list, other validators must initiate a mortgage to win a place in candidate validators.
Validator Set is a set of 21 addresses. GeneChain blocks can only be produced by nodes that are running in mining mode and binding to an account within these 21 addresses
Validator Set is updated every 200 blocks. Only top 21 accounts.
