# Ingestion

> Learn how Atria reads blockchain data for feeds.

# Ingestion

The Ingestor connects to configured blockchain networks, reads block data, and writes normalized payloads into Atria's block store. EVM networks are supported today, with additional chain families on the roadmap.

## What It Reads

* Blocks with transactions.
* Blocks with logs.
* Debug traces.

## Network Flow

  RPC[HTTP RPC] --> Ingestor
  WS[WebSocket blocks] --> Ingestor
  Ingestor --> Blocks[Block data store]
  Ingestor --> State[Chain state store]
```

## Realtime and Fallback

The Ingestor can listen for new blocks over WebSocket and uses polling fallback so feeds can continue processing when a WebSocket signal is delayed or unavailable.
