consensus

Borrow the Latin cōnsēnsus ("consent, consistency, consistency") from cōnssentiō (see "agree, feel together, agree") see consent

General agreement to exercise some degree of discretion in decision making and follow-up between members of a particular group or community, groups or groups

VBFT is a new agreement algorithm combining PoS, VRF (verifiable random function), and BFT. This is the core integrity algorithm of OCE (Ontology Consensus Engine). VBFT supports the scalability of the consensus group, can guarantee randomness and fairness generated by the consensus group via VRF and quickly reach the state final decision. Nodes in the candidate network do not participate in consensus, but are updated to the latest consensus block on the block chain maintained by them in real time, while staying synchronized with the consensus network. The candidate network also monitors the state of the consensus network, verifies the consensus block, and supports the management of the ontology network.

Ontology consensus network is built by ontology consensus management intelligent contract. The consensus management agreement is permanently executed on the ontology network, periodically updating the list of nodes in the consensus network and updating the VBFT algorithm configuration parameters in the consensus network. In the VBFT algorithm parameters, the important parameter is the PoS table of the consensus network node. During the VBFT operation all nodes first randomly select nodes participating in consensus according to the current consensus PoS table and then randomly select nodes to complete the corresponding consensus work round.

To ensure network quality of ontology consensus networks, ontology consensus management smart contracts periodically and automatically update the list of nodes in the consensus network. In the event of a cyber attack, the Consensus Management Intelligence contract also supports forced updates of the list of nodes in the consensus network by equity-based voting. Smart contract renewal The period from the consensus network is block. After each updated consensus network has completed a given number of block consensus, the alternate node proposal for the next block builds a consistency management smart contract transaction and sends it as the first transaction in the block the next proposal It must be packaged in blocks. . Corresponding agreement verification and verification nodes will also validate the proposed node so that the agreement management transaction is included in the block proposal.
