WebApr 10, 2024 · Blockchain stores data in a secure and decentralized way across a network of computers. Each block in the chain contains a number of transactions, and each block is linked to the previous block through a cryptographic hash function. This creates a continuous chain of blocks, hence the name "blockchain.” duwel photography
