wholesale black diamond jewelry What is the basic principle of blockchain? Why are many companies using it?

wholesale fashion jewelry thailand In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential order in order, and is not tampered with and irrefutable distributed ledger in the way of passwordology.
In broad, blockchain technology uses blockchain data structures to verify and store data, use distributed node consensus algorithms to generate and update data, and use cryptography to ensure the security of data transmission and access. A new distributed infrastructure and computing method of programming and operating data are used to programming and operating data with intelligent script code.
Pucting the principle
The blockchain system consists of data layers, network layers, consensus layers, incentives, contract layers, and application layers.
The basic data and basic algorithms such as the underlying data block and related data encryption and timestamp of the data layer; the network layer includes a distributed networking mechanism, data communication mechanism, and data verification mechanism; The main encapsulation of various consensus algorithms of the network node; the incentive layer integrates economic factors into the blockchain technology system, mainly including economic incentive issuance mechanisms and distribution mechanisms; It is the basis for the programmable characteristics of the blockchain; the application layer is encapsulated with various application scenarios and cases of the blockchain. In this model, the chain block structure, the consensus mechanism of the distributed node, the consensus computing power -based economic incentive and the flexible programming smart contract based on the timestamp -based, the consensus computing power is the most representative innovation point of the blockchain technology.

big bold jewelry wholesale Blockchain is an literal translation of English. The global Bitcoin miners dug out a block every 10 minutes, which contains 12.5 bitcoin (previously 25, and then 50). Blocks have all been stored in a file since the history, and they are together with time as a shaft, so they are called quite image.
Since the blockchain is not stored in a central service, it is scattered in the Bitcoin wallet all over the world. After you download the Bitcoin wallet, you must synchronize this blockchain file with the Bitcoin wallet around the world (now there are more than 140 GB), and then the Bitcoin collection and payment can be performed. There are millions of computers around the world that have this file. Hackers or heart -consuming testers want to tampering with Bitcoin's trading history, they must modify the documents in millions of computers.
This is an irreplaceable task.
This is also the value of the so -called "decentralization", which also reflects the absolute security of the blockchain, which is especially important for the financial industry.
Therefore, so many companies and institutions will be pursuing the blockchain. In fact, the blockchain is a by -product of Bitcoin. Its mechanism can be separated from mining and virtual currency, and it runs independently. However, what is currently applied to the blockchain is so good, only virtual currency is considered worthless by many people. Other industries are still sought after. Just like a fashionable vocabulary, hanging on his mouth as a talk.
