According to reports, a recent document issued by the State Intellectual Property Office showed that the Bank of China submitted a patent on the expansion of the blockchain. It is reported that this is not the first time the Bank of China has been involved in the blockchain. In this patent, the problem of blockchain chain trading system data growth will lead to tight storage space, and blockchain expansion is crucial.
With the fissure of cryptocurrencies such as Bitcoin, the blockchain technology on which cryptocurrencies depend is gradually becoming known. At present, more and more enterprises have begun to enter the blockchain, including the Bank of China, one of the four major state-owned commercial banks.
On February 24th, according to documents released by the State Intellectual Property Office (SIPO) this Friday (February 23), Bank of China submitted for the first time on September 28, 2017 a patent on blockchain expansion.
According to the content of the patent application:
The application provides a blockchain data compression method and system. The method includes: receiving, by the full amount of nodes, the compressed transaction request sent by the client; compressing the corresponding block into a data block according to the compressed transaction request, and transferring the data block to the data storage system; calculating the data block hash value according to the data block, Generating a compressed transaction according to the data block hash value, establishing a mapping relationship between the compressed block identifier, the data block identifier, and the compressed transaction identifier; and publishing the compressed transaction and the mapping relationship to the blockchain transaction system. The application can solve the problem that the storage space is tight due to the continuous growth of the blockchain transaction system data without losing traceability and irreversible modification.
It is understood that in the blockchain technology, we store the data in a block, and each block has a certain size limit. For example, the block size of Bitcoin has a maximum capacity limit of 1MB.
Block capacity is small, easy to block the transmission and storage, and will not cause storage pressure on each block chain node, but the block capacity is small, and today, bitcoin transactions are more and more frequent, it is completely useless. It will lead to longer and longer waiting for the transaction.
Therefore, blockchain expansion is critical.
It is also worth mentioning that this is not the first time that Bank of China has been involved in the blockchain. As early as the first half of 2017, Bank of China quietly launched a blockchain e-wallet BOCwallet and cooperated with Chinese Internet giant Tencent to pilot financial Application blockchain.
STP series plating rectifier power supply is an economical rectifier power supply made with high-frequency switching technology based on IGBT switching devices. It is an industrial power supply product developed by our company for electroplating, electrolysis, water treatment, hard oxidation and other industrial applications.
This series of electroplating power supplies are featured for complete control functions, stable performance, and competitive cost performance. Compared with the thyristor-based SCR plating rectifier power supply, the switching mode plating rectifier power supply has much higher efficiency. Under the same output power, up to 20% ~ 30% power loss can be reduced for the customers. This series of electroplating power supplies can reach ultra-high DC output of up to 2000KW with Max. current at 50000A.
The surface treatment industry does not have high requirements for plating DC power supply ripple, and most of models required for plating application are low-voltage and high-current output. The electroplating rectified power supply product removes the unnecessary LC circuit components at the input and output ends, and is targeted at the stability of the output current and the long-term operation capability of the high-frequency rectified power supply to meet the needs of the surface treatment process. In order to overcome the application's harsh environment and long-term high current working conditions, the power supply basically adopts the water-cooling method, and the internal components of the power supply are treated with three preventions, which can realize the effective heat dissipation of the power supply and the effective protection of the internal components of the power supply to improve the reliability of the rectifier power supplies.
