| - | **Delegated Byzantine Fault Tolerance (dBFT)** is a sophisticated algorithm meant to facilitate consensus on a [[dido:public:ra:xapend:xapend.a_glossary:b:blockchain|blockchain]]. Although it is not in common use as of yet, it represents an alternative to simpler proof of stake, proof of importance, and proof of work methods. | + | **Delegated Byzantine Fault Tolerance (dBFT)** is a sophisticated algorithm meant to facilitate consensus on a [[dido:public:ra:xapend:xapend.a_glossary:b:blockchain|blockchain]].

| **Delegated Byzantine Fault Tolerance (dBFT)** consensus was introduced by NEO, often called the //“Ethereum of China”//. This Chinese blockchain plans to achieve the “smart economy” by digitizing assets and providing smart contracts on the blockchain. | **Delegated Byzantine Fault Tolerance (dBFT)** consensus was introduced by NEO, often called the //“Ethereum of China”//.

| - | According to its creators, the voting system of dBFT allows large-scale participation, in a similar way to the Delegated Proof-of-Stake consensus. This allows the holder of a NEO token to support a specific ‘bookkeeper’ through a vote. The selected group of bookkeepers then use the Byzantine Fault Tolerance mechanism to reach a consensus and generate more blocks. | + | According to its creators, the voting system of dBFT allows large-scale participation, in a similar way to the Delegated Proof-of-Stake consensus.

| - | One of the strongest points of using the dBFT mechanism is its absolute finality. After final confirmation, a block can not be bifurcated, so the transaction can’t be revoked or rolled back. However, this irrevocability is a two-edged sword if and when a bifurcation is needed. | + | One of the strongest points of using the dBFT mechanism is its absolute finality.

| The finality of dBFT is somehow guaranteed because NEO is not a wholly distributed network. Despite NEO’s efforts to take this direction, there are currently just seven nodes and a few delegates operating on the blockchain. The majority of these are connected to the NEO council.(( | The finality of dBFT is somehow guaranteed because NEO is not a wholly distributed network.
