Description
Technical field
The present invention relates to block chain technical field, specifically a kind of block chain transmission method building trusted node/satellite node and system.
Background technology
Block chain is a kind of novel decentration agreement, can store digital cash transaction or other data safely, and information can not be forged and distort, it is possible to automatically perform intelligence contract, it is not necessary to the examination & verification of any centralization mechanism. Transaction both can be the such digital cash of bit coin, can also be the digital assets such as credits, equity, copyright, block chain technology solves Byzantium's general's problem, greatly reduces trust cost and the accounting cost of applied economics, the property rights system Internet era of having redefined. Block chain (Blockchain) is the distributed data base system participated in by network node, and its feature is to change, and can not forge, it is also possible to be understood as account book system (ledger). Time stamp server is by the one group of data existed with block (block) form, implement random hash and add timestamp, and this random hash is broadcasted, just as the posting of news or usenet (Usenet). Obviously, this timestamp is able to verify that particular data is inevitable to be existed really in certain special time, could obtain corresponding random hash value because only that be present in this moment. Previous timestamp should be included in its random hash value by each timestamp, and a timestamp before is strengthened (reinforcing) by each timestamp subsequently, material is thus formed a chain (Chain). And with the speed extension of ten minutes newly-increased blocks, this main chain, after often increasing a block, all can be broadcasted to the whole network, so that every Radix codonopsis pilosulae and the computer of digital cash transaction there is copy.
For any one block in block chain, the path arriving wound generation block only has one, but, from wound generation BOB(beginning of block), can forked situation occur. Such as one the block chain at global network node-node transmission, when between country, network interrupts, block chain arises that bifurcation problem. And transaction payment cannot be completed in the place not having the Internet to connect.
Summary of the invention
It is an object of the invention to the shortcoming for prior art, a kind of block chain transmission method building trusted node is proposed, block chain is transmitted by network node, also include building trusted node, when network node or trusted node exist at least two new block simultaneously, the new block that described trusted node produces is joined main chain.

In technical solution of the present invention, network node refers to all terminal nodes participating in business and producing block. Trusted node is to include the network node of key, and the block that trusted node produces is encrypted by key. Key is issued by virtual certification authority, and virtual certification authority is a key mandate authoritative institution, and it is prior art that concrete technology realizes process, is not repeated in technical solution of the present invention.
The block chain transmission method of the structure trusted node of the present invention, including as follows:
1, build trusted node, make trusted node have private key
Block chain transmits between network node, and network node is all terminal nodes participating in business and producing block. And the trusted node built has the key issued by virtual certification authority. Virtual certification authority is a key mandate authoritative institution, and it is prior art that concrete technology realizes process, is not repeated in technical solution of the present invention.
2, new block is selected to add main chain
The block that trusted node produces is encrypted by trusted node by key.
When network node or trusted node exist at least two new block simultaneously, the new block that described trusted node produces is joined main chain. Described existence includes new block that own node produces and receives the new block that other network nodes or trusted node produce
When network node or trusted node exist at least two new block simultaneously, and when being absent from the new block of described trusted node generation, judge to select one of them new block to add main chain according to strategy. Described determination strategy parameter setting as required, such as judges with difficulty according to the height of block. Such as: when a network node receives two new block: block A and block B, and block A and block B is produced by trusted node, one of them block being selected to join main chain, first judge the height of block A and block B, the block selecting aspect ratio higher joins main chain; If block A is identical with the height of block B, comparing difficulty, the block selecting difficulty relatively larger joins main chain. The height of described block refers to: newly generated block is added in block chain, assume that this new block is effective, so this new block is marked as the height of current block, is namely exactly the difference of current block to first block (genesisblock). The difficulty of block refers to the difficulty in computation producing this block.
When network node or trusted node exist at least two new block simultaneously, and when there is the new block no less than two described trusted node generations, judge that the new block selecting one of them described trusted node to produce adds main chain according to strategy.Described determination strategy sets as required, such as judges with difficulty according to the height of block.
