NEO ($NEO) has announced the integration of a new consensus mechanism, Byzantine Fault Tolerance mechanism (dBFT 2.0) onto its mainnet. dBFT 2.0 adds transaction finality onto NEO for the first time, with blocks processing in 15 seconds in a bid to increase financial adoption. The consensus mechanism also adds a reintegration feature for failed nodes and a 'commit phase' to stop blockchain forks.
