# Old Faithful Historical Archive

Old Faithful is Triton's open-source solution to the Solana historical ledger problem, making the entire history of Solana accessible to everyone. Sponsored by the Solana Foundation, this project empowers you to explore Solana's blockchain from genesis to the latest block.

## Key Features

* **Full Historical Access:** Retrieve any Solana block from previous epochs!
* **Flexible APIs:** Access data via standard JSON-RPC or high-performance gRPC streams.
* **Self-Hosted or Managed:** Run your own archive node (requires significant storage) or use Triton's managed endpoints.
* **Open Source:** Built in the open for transparency and community collaboration.

## Getting Started

Old Faithful is automatically integrated into your Triton One subscription. By making a `getBlock` or `getTransaction` call for historical data, our systems will intelligently route you to Old Faithful.

### gRPC

Most JSON-RPC methods can be made with gRPC and for greater efficiency we've also implemented **StreamTransactions** and **StreamBlocks** which allow you to filter large troves of data server side and receive only what's relevant for you. You can see examples in the gRPC [docs](https://docs.old-faithful.net/references/grpc-methods/examples#streaming-methods) page.
