# Blocks ◽

Blocks are the building blocks of blockchains and rollups.

A block contains transactions which will alter the state of an EVM system incrementally. Transaction within a block can only be executed one after the other, not in parallel.

### Table Details

| Property | Value |
| - | - |
| Table Name | `b3.raw.blocks` |
| Table Status | Deprecated ◽ |
| Unique Key | `timestamp`, `number` |
| Clustering Key(s) | `to_date("timestamp")` |
| Search Optimization | `miner` |

### Table Columns

| hash | VARCHAR(66) | Unique identifier of a block. |
| parent\_hash | VARCHAR(66) | Unique identifier of the block preceding this block, also known as the parent block. |
| nonce | VARCHAR(42) | The hash of the generated proof-of-work. null if pending. |
| sha3\_uncles | VARCHAR(66) | An array of uncle hashes. |
| logs\_bloom | VARCHAR(16777216) | The bloom filter for the logs of the block. |

| miner | VARCHAR(42) | The address of the beneficiary to whom the mining rewards were given. |
| difficulty | NUMBER(38,0) | The integer of the difficulty for this block. |
| total\_difficulty | VARCHAR(66) | The integer of the total difficulty of the chain until this block. |
| size | NUMBER(38,0) | The size of the block, in bytes, as determined by the gas\_limit. |
