meditation jewelry wholesale Recently, I have been understanding the mobile blockchain. Is there a big coffee that understands the blockchain?

wholesale jewelry manufacturers uk The blockchain consists of a block link generated by a string of cryptographic algorithms, so it is called the blockchain.
Each block is full of transaction records. The block forms a chain structure in order, which is the blockchain ledger.
Blockchain technology divides the data needed in the database into different blocks. Take Bitcoin as an example. When generating a new block, the miner needs to calculate the new hash value and random number based on the hash value, new trading block and random number of the previous block. The information link is behind the previous block, and the front and back are connected in the order of time to present a complete set of data. That is to say, each block is generated on the basis of the previous block data, which guarantees the uniqueness of the blockchain data.
Each blockchain database is essentially a event chain that is connected in series in order. It uses the password mechanism specified in the agreement to certify to ensure that it will not be tampered with and forged. The popularity of blockchain and Bitcoin, many related TOP domain names have been registered, which has a great impact on the domain name industry.
Blockchain technology has three obvious characteristics: openness, security and uniqueness.
The publicity mainly refers to the storage information in the blockchain is completely disclosed to all participants. This is mainly determined by the blockchain point -to -point network storage method. In the blockchain network, each node can store a copy of the blockchain, and the uniqueness of the blockchain can ensure that this copy is between different nodes. exactly the same.
A security mainly refers to the information stored in the blockchain blocks after digital encryption technology processing. Only private key holders can decrypt the information to obtain real information. Other members can only see and verify the integrity and uniqueness of the information, but they cannot see real information.
The characteristics of uniqueness are mainly because the information on the blockchain cannot be tampered with once the chain is on, so it has uniqueness. Of course, the uniqueness mentioned here also includes the uniqueness of space, that is, all nodes have only one information of the same version, including the uniqueness of time, that is, historical data cannot be changed. This uniqueness also refers to the characteristics of the only main chain during the operation of the blockchain, and once other chains appear, a bifurcation occurs. The emergence of the fork will cause a copy of the blockchain in the two different space dimensions. Of course, solving this problem also needs to be avoided by setting a reasonable consensus rule.
The blockchain does not have the division of mobile and non -mobile terminals, if it is also a gimmick.
