A kind of Trusted Digital transaction in assets method
Technical field
The present invention relates to internet information alternating-current technique, more particularly, to one it is based on block chain, multicenter, can Across digital asset method of commerce merchandised, believable.
Background technology
Term is explained：
Block chain
Block chain is a kind of recording technique of decentralization, any number of nodes in participation system, in a period of time system The data of full detail exchange, recorded a block, while the fingerprint for generating the block is used for chain by the method for cryptography Connect next area's block sum check.All nodes that participate in of system assert record and verification jointly, it is common assert record whether be it is true, together When each node can replicate the copy for obtaining a complete documentation.Compared with traditional book keeping operation technology, its feature is as follows：
（1）The chain that system node is safeguarded jointly constantly increases, and is only possible to addition record, and the record occurred can not all be distorted；
（2）Decentralization, multicenter, can reach common understanding without the control of concentration in other words；
（3）Ensure that transaction can not be denied and destroyed by the mechanism of cryptography, and protect the privacy of user information and record;
In numerous block chain business applications, bit coin block platform chain its imitated by extensive infrastructure and powerful network Should, it is considered at last as the bottom of block chain field standard.
Merkle trees
Merkle trees are a kind of Hash binary trees, it is a kind of data for being used as quick conclusion and verification large-scale data integrality Structure.This binary tree includes cryptographic hash.Term " tree " is often used to description one kind in Computer Subject has branch Data structure, but tree be usually squeezed display, " root " the top of figure at the same time " leaf " in the lower part of figure.
In bit coin network, Merkle trees are used to conclude area's All Activity in the block, while generate whole hand over The digital finger-print easily gathered, and provide a kind of high effective way for verifying block and whether there is certain transaction.Generation one is complete Merkle trees are needed recursively to Hash node to carrying out Hash, and newly-generated Hash node is inserted into Merkle trees, Until only remaining a Hash node, which is exactly the root of Merkle trees.Used twice in the Merkle trees of bit coin SHA256 algorithms, therefore its cryptographic hashing algorithm is also referred to as double-SHA256.
2017, digital encryption token market welcome blowout growth, according to the statistics of coinmarketcap.com, Cut-off was to August in 2017 4 days, and Digital Radio encrypts token transactions currency type more than 1000 kinds, and total market capitalisation reaches 101,300,000,000 U.S. dollars, together Whole world turnover is also up to 2,300,000,000 U.S. dollars when smaller than growth by 773%, only 24, but digital encryption token market is asked there is also following Topic：
Transaction is highly concentrated in only a few exchange
Current exchange species is various, but Digital Radio encryption token transactions are but highly concentrated in the exchange of only a few. When bit coin August 4 days 24 is small exemplified by the turnover of the whole world, nine exchanges such as Bitfinex carry 90% bit coin transaction Volume.
