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?

01
The consensus of a single mechanism
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,

02
The advantage of hybrid mechanism
The biggest advantage of the hybrid mechanism is to 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 of hybrid consensus, can make up for a single consensus mechanism inefficient, lose security protection or sacrifice centralized degree of defects,


Wisdom Chain miners node list

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, establish selection mechanism at the same time, if the node accounting fraud in 30 seconds or bias records will be eliminated, thus, speed, safety and decentralized nature got to two or morethings,


Wisdom Chain block overview

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,
