# Overview

> Core Ethereum Virtual Machine (EVM) Compatible Schemas on Allium.

Ethereum Virtual Machine (EVM) schemas share similar data structures across all EVM-compatible blockchains indexed by Allium.

We support the following data verticals

## Verticals

### Raw Data

Raw blockchain data in its most fundamental form, providing the foundation for all derived analytics.

| Schema | Description                                             | Tables                                                       |
| ------ | ------------------------------------------------------- | ------------------------------------------------------------ |
| Raw    | Primary blockchain data directly from nodes             | blocks, transactions, logs, traces, traces\_evm\_transfers\* |
