What is Block in Ethereum?

In Ethereum, a block is a collection of transactions and other data that are added to the Ethereum blockchain. Each block contains a unique code called a “hash” that allows it to be distinguished from every other block, as well as a “hash” of the previous block in the chain, linking the two.

• In addition to transactions, blocks in Ethereum also contain other types of data such as smart contract code and the results of that code being executed. Each block also includes a timestamp and information about the miner who mined the block.
• The blocks in Ethereum blockchain are added through a consensus mechanism called Proof of Stake, which is different from Bitcoin’s Proof of Work mechanism.
• Ethereum blocks are mined at a fixed rate of around 15 seconds, which makes the Ethereum blockchain faster than Bitcoin’s, which has a block time of 10 minutes.
• An Ethereum block is a collection of transactions that are processed and verified by the network’s nodes. Each block contains a block header and body.
• The block also contains the transactions themselves, which are grouped into a single Merkle tree. This allows for efficient verification of transactions without having to include the entire block data in the header.

In blockchain technology, a block is a record of new transactions that have been added to the blockchain. Each block contains a unique code called a “hash” that allows it to be distinguished from every other block, as well as a “hash” of the previous block in the chain, linking the two. This creates a chain of blocks, or a “blockchain,” that cannot be altered or tampered with because any change to a block would also change its hash and would therefore no longer match the hash of the previous block. This is what makes blockchain technology secure and tamper-proof.
The Ethereum blockchain is a decentralized platform for building decentralized applications, it is a blockchain-based distributed computing platform, featuring smart contract functionality.
