# Blocks

Blocks are the fundamental units of data storage in the NEAR blockchain, containing a set of transactions and the state of the network at a specific point in time. Each block includes a hash, height, timestamp, and links to predecessor and successor blocks, ensuring the chain's integrity and chronological order.
