    high fashion costume jewelry wholesale Blockchain is a digital ledger that can be borne, and will record all transactions that have occurred and have been recognized by the system. It is equivalent to the family mobilization of the family. You are booking the book. Your father and mother are also taking accounts. They can all see the general account, but the saved information cannot be tampered with.
    The blockchain has decentralization, openness, and safety characteristics. Blockchain technology does not rely on additional third -party management agencies or hardware facilities, and there is no central control; the blockchain technology foundation is open source. In addition to the private information of the parties to the parties to be encrypted, the data of the blockchain is open to everyone; As long as you cannot control 51%of all data nodes, you cannot control the modification of network data wantonly to ensure the security of the blockchain.

    2008 The concept of blockchain was given by Nakamoto. Subsequently, the blockchain became the core component of the electronic currency Bitcoin, and was a public account book for all transactions. By using the point -to -point network and distributed timestamp server, the blockchain database can perform independent management.

    The expansion information:
    The type of blockchain
    1, public blockchain
    Any individual or group in the world can send transactions, and transactions can get the area in the area Effective confirmation of the blockchain, anyone can participate in its consensus process. The public blockchain is the earliest blockchain and the most widely used blockchain. The virtual digital currencies of the major Bitcoins series are based on the public blockchain. Essence
    2, united (industry) blockchain
    The industry blockchain (Block Chains): The nodes of multiple pre -selected nodes are specified inside a group as the bookkeeper. The node jointly decided (the pre -selected node to participate in the consensus process). Other access nodes can participate in the transaction, but the questioning process (essentially the custody of the accounting, but only becomes a distributed bookkeeping, how much the pre -selected node, how to determine each one for each one, how to determine each one for each one Block bookmakers have become the main risk points of the blockchain), and anyone else can make a limited query through the API opened by the blockchain.
    3, private blockchain
    only using the blockchain general account technology for bookkeeping, it can be a company or individual, enjoy the authority of the blockchain, this chain and other other and other other The distributed storage scheme is not much different.

    peruvian gold jewelry wholesale Blockchain, English, is a word composed of blocks and chains. As the name suggests, the block has a chain structure. The blockchain is a chain structure connected by the block in order. It is a technical solution that collectively maintains a reliable database through decentralization and trust.
    Blocks refer to the data packet that carries transaction data on the blockchain network. It is a data structure that is marked with the labeling time stamp and the hash value of the previous block. And confirm the transaction in the block. The chain is made from the sequence of the block in the sequence of the occurrence of the layer of the layer. It is a log record of block transaction records and state changes.

    wholesale pearl cage jewelry usa 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 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.
