At present, there is a consensus mechanism in the global public chain infrastructure. It stipulates how to compete between the nodes. The most popular consensus mechanism at this stage is OW, POS, DPOS, PBFT and DBFT. Its speed, safety and centralization degree have different emphasis. However, some public chains choose to use the hybrid consensus mechanism, such as ZIL adopts the POW+PBFT's mixed consensus mechanism, Wisdom Chain adopts the DPOS+Pow's mixed consensus mechanism, and what is the advantage of adopting the hybrid consensus mechanism?
First of all, the early bitcoins and Ethereum adopted a single consensus mechanism, which resulted in their missile running speed and being unable to be 2 in the ltd. environment. Over the EOS USES the consensus mechanism of DPOS, all the transactions are recorded by the super node on the chain, which has greatly improved the efficiency, but it has lost another major feature of the blockchain - the security brought by decentralization,
Therefore, the public chain with a single consensus mechanism is doomed to not have to both efficiency and security and decentralization.
Advantages of hybrid mechanism
The biggest advantage of hybrid mechanism is that it can learn from each other 's strengths. Hybrid consensus means that two or more consensus mechanisms are applied to The physicist architecture of The same blockchain public chain. The Reasonable use of mixed consensus can make up for The defects of low efficiency, loss of security protection, or sacrifice of centralization degree under caused by single consensus mechanism.
Wisdom Chain's ideas in this regard are quite creative. It adopts the hybrid mechanism of DPOS+POW, and the two accounts run simultaneously to make up for the disadvantage of any single consensus mechanism. DPOS mechanism has high efficiency. It is responsible for selecting legal transactions from the transaction storage pool, packaging them into blocks, and then broadcasting them to the network through P2P protocol. The implied POW requires miners to complete a certain amount of work proof to prevent the main chain from branching. At the same time, the elimination mechanism is established. If the nodes make false accounts or biased records within 30 seconds, they will be eliminated. As a result, speed, security and decentralization are taken into account.
Of course, there are still some problems to be solved in the hybrid consensus mechanism, but any technology is not achieved an overnight, and it is impossible to have a smooth journey, by the Wisdom Chain team made a detailed and the in - the depth thinking on the key technical difficulties and put forward feasible technical solutions. In the future, with the popularization Of blockchain technology, the problem Of hybrid consensus mechanism will surely be solved one by one.

Underlying architecture of the current global Chain mechanism have a consensus, it states how to competition between nodes, charge to an account at this stage the most mainstream consensus mechanism is OW, POS, DPOS, PBFT and DBFT, its speed, safety and centralized degree each have emphasize particularly on, but there are some male Chain choose to use a mixed mechanism of consensus, such as + ZIL adopted POW PBFT mixed consensus mechanism, Wisdom Chain mechanism, adopted the hybrid DPOS + POW consensus that what are the benefits of the hybrid mechanism of consensus?
First of all, early COINS, etheric fang are adopted single consensus mechanism, caused they run slow, cannot be applied to the business environment, although the EOS using the consensus of the DPOS mechanism, all transactions are recorded by the node to a super node on the chain, there is a big promotion in the efficiency, but has lost another big characteristic of block chain - decentralization brings security,
The consensus of using a single mechanism of the chain, as a result, condemned to the efficiency and security, the trade-off between decentralization degree,
The advantage of hybrid mechanism
The hybrid mechanism is the biggest advantage of each director, mixed consensus that use two or more consensus mechanism in the same block in the underlying architecture of chain and chain, reasonable use mixed consensus, can make up for a single consensus mechanism inefficient, lose security protection or sacrifice centralized degree of defects,
Wisdom Chain of creative thinking in this aspect, it USES the DPOS + POW mixing mechanism, two books and running mechanism make up for any single consensus in the form of disadvantage, DPOS mechanism of high efficiency and is responsible for the choose legal transactions from the transaction storage pool, to pack it into pieces, and then through the p2p protocol will be broadcast to the network, while the implicit POW need to accomplish a certain number of miners work proved that prevent main Chain bifurcate, elimination mechanism at the same time, the accounting fraud in 30 seconds or if the node has a bias record will be eliminated, thus, speed, safety and decentralized nature got to two or morethings,
Mixing mechanism of consensus, of course, there are some problems to be solved, any technology is not achieved overnight, but could not bon voyage, but Wisdom Chain team made detailed in-depth thinking of key technical challenges and proposes the feasible technical scheme, in the future, with the popularity of block Chain technology, mixing mechanism of consensus problems will certainly be one by one,
