Block Hash
A block hash is a unique cryptographic identifier assigned to each block in a blockchain. Essentially, each hash is calculated using the previous hash. This mechanism ensures that any alteration in the block's content would result in a completely different hash. As a result, the chain’s integrity and immutability is ensured.
For web3 developers, block hashes are essential for verifying the authenticity of blocks, tracking blockchain history, and referencing specific blocks in applications. Utilizing block hashes enables developers to build secure and reliable systems that depend on the trustless nature of blockchain technology.
