Decentralization: Blockchain technology operates without a central authority or middlemen, which means that transactions are processed and verified by a network of peers, promoting trust and security.\n\n2. Distributed ledger: A distributed ledger is a shared, tamper-proof and synchronized record of transactions across a network of computers. Each participant has a copy of the ledger, ensuring transparency and accountability.\n\n3. Blocks: Blocks are the building blocks of a blockchain, containing a series of transactions recorded together. Each block is linked to the previous one through a cryptographic hash, forming a chain of blocks.\n\n4. Cryptography: Cryptography plays a crucial role in blockchain technology, ensuring the security and privacy of transactions. Encryption techniques protect the data in each block, and secure peer-to-peer networking ensures that transactions are transparent without revealing sensitive information.\n\n5. Consensus","a":"Hash algorithm: The hash algorithm is used to generate the hash value of the block, ensuring the consistency and immutability of the block data. The hash algorithm converts the data within the block into a fixed-length string, and any slight changes  in the data will result in significant changes in the hash value."}]}],"pr":"4a196ccb742729f1b19d299b2afb5ac5758d4d6d19a8f0f51af669346e31e957"}
