# Streams FAQ & Resources

## Frequently Asked Questions

### What is Quicknode Streams?
Streams is a data ingestion and streaming solution for web3 applications that enables you to efficiently collect, process, and store both raw and filtered blockchain data in real-time and historically.

### How do I access Quicknode Streams?
You can access Streams through the [Quicknode Dashboard](https://dashboard.quicknode.com/) or via the [Streams REST API](/content/docs/streams/rest-api/index.html), both providing interfaces to manage your data pipelines.

### What is filtering in Streams?
Filtering allows you to define custom Go or JavaScript [filters](/content/docs/streams/filters/index.html) that process blockchain data on Quicknode's infrastructure before it reaches your destination, reducing data transfer and processing overhead on your systems.

### What types of destinations does Streams support?
Streams supports various backend systems including [webhooks](/content/docs/streams/destinations/webhooks/index.html), [Amazon S3](/content/docs/streams/destinations/s3/index.html), [PostgreSQL](/content/docs/streams/destinations/postgresql/index.html), [Azure Blob Storage](/content/docs/streams/destinations/azure/index.html), and [Kafka](/content/docs/streams/destinations/kafka/index.html), supporting both batch and real-time delivery modes.

### How does Streams ensure data reliability?
Streams provides **exactly-once delivery** of blocks, receipts, and traces in finality order, and processes blocks sequentially, waiting for confirmation that each block or batch was successfully delivered before proceeding.

### Which blockchain networks are supported by Streams?
Over 60 chains are supported, including Ethereum, Solana, Bitcoin, Arbitrum, Base, Polygon, and Avalanche, with availability across mainnet and testnet environments. See [Supported Chains](/content/docs/streams/supported-chains/index.html) for the full list.
