BlockchainBlockchain is a data structure in which blocks containing transaction information are sequentially linked from back to front. It can be stored as a flatfile (a file that contains records that have no relative relationship), or it can be stored in a simple database. The Bitcoin Core client uses Google\u2019s LevelDB database to store blockchain metadata. Blocks are linked in this chain in an orderly manner from back to front, and each block points to the previous block.The blockchain is often regarded as a vertical stack, with the first block as the first block at the bottom of the stack, and then each block is placed on top of other blocks. After using the stack to visualize the concept of stacking blocks in sequence, we can use some terms, such as: \u201cheight\u201d to indicate the distance between the block and the first block; and \u201ctop\u201d or \u201ctop\u201d to indicate The newly added block.Perform SHA256 encryption hash on each block to generate a hash value. Through this hash value, the corresponding block in the blockchain can be identified. World-class digital goods-currency exchange-easy. At the same time, each block can refer to the previous block (parent block) through the \u201cparent block hash value\u201d field of its block header. In other words, each block header contains the hash value of its parent block. In this way, the hash value sequence that links each block to its parent block creates a chain that can be traced back to the first block (the genesis block).Since the block header contains the \u201cparent block hash value\u201d field, the hash value of the current block is also affected by this field. If the identity of the parent block changes, the identity of the child block will also change. When there is any change in the parent block, the\u2026<\/p>","protected":false},"excerpt":{"rendered":"
