How much do you know about Block chain-Alliance chain

DaDa / tr. by Phil Newell)

Before we briefly understand the public chain and private chain, today let DaDa introduce the alliance chain to you.

Consortium blockchain refers to a block chain managed by several institutions, each of which runs one or more nodes, in which the data only allows different institutions in the system to read, write and send transactions, and jointly record transaction data. Each participant in the alliance chain does not have to worry about where his own data is stored, the data generated by himself can only be seen by himself, and the data of other participants can only be seen through the authorized key of the other party, so the problems of data privacy and security can be solved. At the same time, decentralization can be achieved.

The characteristics of the alliance chain

1. Partial decentralization

Unlike the public chain, the alliance chain is only owned by the members within the alliance to some extent, and it is easy to reach a consensus, because after all, the number of nodes of the alliance chain is very limited.

two。 Strong controllability

The public chain cannot be tampered with once the blockchain is formed, which is mainly due to the fact that the nodes of the public chain are generally massive. For example, there are too many Bitcoin nodes, and it is almost impossible to tamper with the block data, while the alliance chain can change the block data as long as most of the institutions reach a consensus.

3. Data will not be made public by default

Unlike the public chain, the data of the alliance chain is only accessible to the organizations in the alliance and their users.

4. The transaction speed is fast.

Like the private chain, the alliance chain is essentially a private chain, so because of its few nodes, it is easy to reach a consensus, and the transaction speed is naturally much faster.

Compared with the operating space and efficiency of the private chain, the alliance chain is of greater value; compared with the completely decentralized uncontrollable and privacy security issues of the public chain, the alliance chain becomes more flexible and operable.

Application of Alliance chain

Previously, China UnionPay and Everbright Bank jointly used the interest chain technology block chain platform to build a multicenter trusted POS electronic purchase order system to announce the completion of the preliminary test. This test means the birth of the first domestic application scenario of alliance chain across physical space and based entirely on the Internet environment. The test of multi-center POS electronic purchase order system based on interest chain products of China UnionPay and Everbright Bank marks the successful connection of the first multi-party cross-regional block chain network in China, and is a big step in the development of alliance chain.

In JD.com 's own white paper on blockchain, the application of his own alliance blockchain is mainly concentrated in five areas: commodity anti-counterfeiting traceability, contract and invoice anti-counterfeiting public welfare traceability, big data security, insurance fraud prevention and transaction settlement. Among them, JD.com 's goal for his own alliance blockchain is to create a blockchain infrastructure for enterprise applications, and to provide enterprises with blockchain technical solutions that can effectively solve business pain points. and in the process of research and development and application of blockchain, always pay attention to the five aspects of performance, function, security, contract and compliance, and focus on the optimization of blockchain technical capability in these five aspects.

However, while the alliance chain brings together many advantages, it also has its own challenges to overcome.

For example, how to use the same underlying block chain technology to adapt to the different business needs of different formats in the alliance?

The more tentacles of the alliance, the higher the universal requirements for the underlying technology, and at present, before the international and national standards for the underlying technology of the blockchain have not been unified, any attempt may be invalidated.

In addition, even if the alliance chain is completed, how to balance the interests and discourse rights of all parties in the alliance chain will also be an important problem for the alliance chain.

Among them, JD.com in his own block chain white paper, the last summary part, also truthfully said: how to establish a better block chain application scene incentive mechanism through the business model, so that each block chain application really produce commercial value, is one of the core challenges of large-scale application of block chain.
