Delegated Byzantine Fault Tolerance (dBFT)
dBFT is a consensus mechanism developed by NEO as an advanced version of Proof of Stake (PoS). It shares similarities with the regular Byzantine Fault Tolerance (BFT) consensus, but incorporates a methodology where individuals meeting specific requirements can become delegates. Within the dBFT consensus method, delegates have the ability to exchange and evaluate proposals put forth by other potential delegates. This approach allows for efficient finalization times and speedy transaction processing. However, critics contend that dBFT may suffer from centralization concerns, as NEO relies on just seven main Consensus Nodes to reach consensus across the network.
