Title
(EN) Consensus system for manipulation resistant digital record keeping
Abstract
(EN)

The disclosure describes a peer-to-peer consensus system and method for maintaining a manipulation resistant updateable shared ledger. The system achieves consensus on a shared ledger between a plurality of peers and prevents double spending in light of network latency, data corruption and intentional manipulation of the system. Consensus is achieved and double spending is prevented via the use of the widest chain metric to choose a single consensus transaction record. A trustable record is also facilitated by allowing stakeholders to elect a set of trusted non-colluding block signers to cooperatively add transactions to the consensus record. The voting mechanism is a real-time auditable stake weighted approval voting mechanism.
