Cryptographic Hashing in Bitcoin
Cryptographic hashing is a fundamental concept in Bitcoin, and it utilizes the SHA-256 algorithm. Hashing converts any data, including transactions, into a fixed-length string of characters, known as a hash. This hash is unique to the data and any change in the data will result in a different hash.
The SHA-256 hash function is crucial for the immutability of the blockchain. Once a block is added to the blockchain, its hash is used to link it to the previous block, creating an unbreakable chain of blocks. Any attempt to alter a transaction within a block would result in a different hash, making the alteration immediately apparent and invalidating the block.
Digital Signatures in Bitcoin Transactions
Digital signatures are essential for verifying the authenticity and integrity of Bitcoin transactions. They are generated using the private key associated with a Bitcoin address. When a transaction is initiated, the sender uses their private key to sign the transaction data.
This signature is then included in the transaction and can be verified by anyone using the corresponding public key.
