# solana.blocks

> Solana block-level data including slot numbers, leader identity, rewards, and transaction counts. Blocks contain transactions which contain instructions that alter the state of the Solana blockchain. Use this data for network throughput analysis, validator performance benchmarking, and infrastructure monitoring.

## Table description

The `solana.blocks` table contains the block data within Solana's blockchain. It can be used to identify block activity and transaction changes over time.
