DEFINITION
Blocks hold batches of hashed and encoded transactions.
Each block includes the hash of the prior block, linking the two, hence forming the chain.
This iterative process confirms the integrity of the previous block, all the way back to the initial GENESIS block.

BLOCKS & TRANSACTIONS
Transactions are batched into blocks, and they are all at once:
- committed
- agreed on
- synchronized
This is to give all the participants time for consensus.

BLOCK VALUES
- timestamp: time the block was mined
- blockNumber: blockchain's length
- baseFeePerGas: min transaction gas fee
- difficulty: mining effort
- mixHash: unique id
- parentHash: block's parent id
- transactions
- stateRoot: system's state
- nonce: proof-of-work hash

- nonce: proof-of-work hash
BLOCK TIME
It's the average time it takes for the network to generate one extra block in the blockchain.
By the time of block completion, the included data becomes verifiable.
it varies depending on the blockchain:
- Ethereum block time: ~15secs
- Bitcoin block time: ~30mins

BLOCK SIZE
The current Ethereum block size (2 Dec, 2021) is around 80Kbs
Blocks have a target size of 15 million gas and a limit of 30 million gas.
The total gas expended by all transactions in the block must be less than the block gas limit.
