Blocks are the containers that hold batches of transactions. Let's explore how to read block data and understand what each field means.

🔍 Understanding Block Fields
Sequential position in the blockchain. Genesis block = 0, next = 1, etc. Higher number means more recent.
Unique identifier (64-character hex string) created by hashing block contents. Changes if anything in the block changes.
Hash of the previous block. This links blocks together into a chain - changing one block breaks all subsequent blocks.
When the block was mined. Not perfectly accurate (can be off by seconds) but gives rough chronological ordering.
Address that produced this block. In PoW they're miners, in PoS they're validators. They receive block rewards + fees.
How many transactions are included in this block. Blocks have size/gas limits, so this varies (50-300+ typical on Ethereum).
⚡ Block Production Stats
Block times vary by blockchain design. Faster ≠ better - there are trade-offs with decentralization and security.
