Although chain block is a new concept, but it relies on technology is not new, such as asymmetric encryption technology, P2P network protocols, etc., like lego, building block is limited, but different combination have a very interesting thing,

Block chain is essentially a value based on P2P transmission protocol, we can not only see the P2P, and can't see the value of transmission, the same, also can't see the value of transmission, and can't see the underlying technology of block chain,

Can say so, chain block is more like a cross subject, combined with the technique of P2P network, asymmetric encryption technology, macro economics, economics, game and so on knowledge, to build a new field - to value the exploration of the Internet,

Then what is the value of the Internet? Value of the Internet can be derived by the full-fledged e-commerce payment business, but, really just for my domain? Obviously this is not enough, tier 1 capital market, the real assets equaling and transfer, securities registration and settlement, the letter and fraud, we think again, our each big electric business platform of professional bad review, malicious brush less single?

Powerful Internet gives us almost zero cost of high speed information transmission channel, without a cheap and reliable value of high-speed transmission channel, so that is block chain will bring,

Chain block is a common distributed general ledger, from a technical point below brief introduction:

Imagine a 100 units distributed database cluster, the situation is the owner of this 100 nodes, in fact, is an institution, and all the nodes in the network, so the agency want to make this 100 database node why is why, in other words it is between 100 nodes in a trusted environment, and is controlled by an entity, the entity has the absolute arbitration division,

Also is such, imagine the 100 nodes were owned by different people, and everyone is the same, the node data is redundant, and all of the nodes are in the middle of a wan, in other words, this is the distrust between 100 nodes, and there is no one entity, it has absolute arbitration,

Now consider the second case, adopt what kind of algorithm (consensus model) can provide a credible environment, make:

Each node data exchange process not been tampered with; Exchange history not been tampered with;

Each node of the data will be synchronized to the latest data, and admitted by consensus to the latest data;

Based on the principle of the minority is subordinate to the majority, and the overall node maintenance data itself objectively reflected the exchange history,

Block chain is essentially to solve above the second case of a technical solution, more specifically should call distributed redundant chain general ledger, the scheme of some elements of chain blocks, in my previous article has summed up some:

Distributed database contains a

Distributed database is the physical carrier of chain block, block chain trading is the logic of the carrier, all the core node should contain all chain data which blocks the

Chain according to the time to serialize the block and block chain is the only main body of the whole network transaction data

Block chain applies only to add to other operating invalid

So as a technical personnel, should not only see the block technology rely on the chain, more should pay attention to block outside the chain point with noodles, taken together, block chain will be much more interesting,
