<figure><img src="/files/OdBDOaLPDNxGr07MRK69" alt=""><figcaption></figcaption></figure>

Satoshi ProtocolBigFat uses [Satoshi Protocol](https://satos.network/) technology, which is built using Near Chain's Chain Abstraction, creating a Bitcoin-like L2 implementation.While [Satoshi Protocol ](https://satos.network/)may seem like a Bitcoin L2, it is actually quite different from most L2 solutions.

#### The key points: <a href="#the-key-points" id="the-key-points"></a>

1. ​[Satoshi Protocol](https://satos.network/) naturally integrates all Near Chain dApps, meaning there’s no need for additional dApp ecosystem building—users already have access to a complete Near ecosystem.
2. ​[Satoshi Protocol](https://satos.network/) allows Bitcoin users to directly sign transactions using their Bitcoin wallet, without needing to create a new wallet.
3. Instant withdrawals: Thanks to Near Chain's Chain Abstraction, [Satoshi Protocol](https://satos.network/) (and BigFat) enables Bitcoin users to complete BTC transaction withdrawals in seconds.
