Description
Technical Field
The invention relates to a system based on a main and sub account book in a distributed account book.
Background
The algorithm generated by the distributed account book technology is powerful and subversive, has the opportunity to change the implementation modes of public and private services, and improves the productivity through a wide application scene.
Ledgers are one of the core elements of business activities from the very beginning of the last years and are used to record a large number of things-most commonly assets like money and property rights. The media for these data records have evolved from mud boards, to papyrus, to kraft papers and paper. However, for so long, electronic computerization of data was the only significant innovation in this area, which initially was simply turning paper data into electronic data. Computer algorithms now make it possible for the first time to collaboratively maintain digital distributed ledgers, which have attributes and capabilities that go beyond traditional paper ledgers.
The distributed ledger is essentially an asset database that can be shared at multiple sites, at different geographical locations, or over a network of multiple organizations. Participants in a network may obtain a copy of a unique, real ledger. Any changes in the ledger will be reflected in all copies, with reaction times in minutes or even seconds. The assets stored in this ledger may be financial, legally defined, physical or electronic. The security and accuracy of the assets stored in the ledger are maintained on the basis of cryptography by controlling the access rights of the ledger through the use of public and private keys and signatures. The records in the ledger may be updated by one, some or all participants together, according to rules of consensus agreed upon in the network.
Blockchains are the underlying technology of such distributed ledgers, originally designed for point-to-point digital today's system bitcoins implemented in 2008. The block chain algorithm enables the transaction of bitcoin to be centralized in the 'blocks' and added into the 'chain' formed by the absorption blocks through the cryptographic signature. The bitcoin ledger is built in a distributed and "license-free" way, and anyone can add a block containing a transaction by solving the cryptographic difficulties required to generate a new block. Currently, the incentive mechanism for this system is to receive a 25-bit dollar reward after resolving the issue and generating each region. Anyone who has only the network and computer examples has the opportunity to solve these cryptographic challenges and add the transaction to the ledger, is called a "bitcoin miner. The ore mining metaphor is proper, so the excavation of the bitcoin consumes a large amount of computer computing power, and therefore, high energy consumption is brought about.
