Decentralization: Blockchain technology relies on a decentralized network of nodes, which means that there is no single point of failure or control. This promotes security and transparency as data is distributed across the network rather than being stored in a centralized location.↵↵2. Blocks and chains: The blockchain is composed of a series of interconnected blocks, each containing a certain amount of data. As new data is added to the blockchain, new blocks are created and linked to the previous block through a cryptographic hash. This forms a chain of blocks, with each block containing a reference to the previous one.↵↵3. Cryptography: Blockchain technology uses cryptographic algorithms to secure the data stored in each block. This includes hashing algorithms, which create a unique identifier for each block, and public-key encryption, which ensures that only the intended recipient can access the data contained in a specific block.","a":"Distributed ledger:  Blockchain is a distributed ledger, where each node stores complete ledger data, including all historical transaction records. Each block contains the ID and hash value of the previous block, forming a chain structure that ensures the traceability of data."}]}],"pr":"066d5d734d04cc0f3545d8da5f14fa88e454d7c8fd88800ab4a2ac694ed5f0dd"}
