1. blockchain is a decentralized ledger, which can keep the actual records of all transactions. For example, when using this technology to manage remittances, the ledger looks like a bank statement, recording information such as amount, date, sender and recipient. The data structure contains encryption technology, which allows each member of the network to manage the ledger safely without centralized execution. The lack of central authority in the system is one of the most influential innovations in blockchain technology
once the information is recorded in the blockchain, it will become permanent and impossible to change or delete. If a user wants to create a new entry (called a block) to the ledger, other users in the network must verify the information they propose to add. Each computer on the network (called a "node") compares the submitted information with the existing ledger. If most nodes can verify the accuracy of the new block of information, it is allowed to become a permanent part of the ledger. Because the blockchain network is composed of computers in multiple locations, even if a certain network is destroyed, the security of the whole data will not be affected
to understand the working principle of blockchain technology, we must first know the data type of each block in Dimon. Except for transaction data, all blocks contain digital fingerprints called hashes. Each unique hash is generated based on the information within the block, so if the data is changed in any way, the hash will change automatically. This cryptography is the key to decentralized authority of blockchain. The new block also contains the imprint of the hash assigned to the previous block and the chain of entries being audited. If the user attempts to tamper with the block data, the hash cannot be authenticated and the entry is rejected.
