# How It Works

👉 **Cross-Chain Transfer Protocol (CCTP)**

CCTP is a protocol to connect decentralized applications (DApps) anonymously and securely on any blockchain.

This is made possible with API calls from any blockchain.

👉 **Validator Nodes**

Galaxy's cross-chain validator nodes allow transfers between different blockchains to be safe. The consensus mechanism used is the delegated proof of stake (DpoS). The users elect the validators.

The status of the blockchains is recorded in Galaxy's cross-chain system once it is known.

👉 **Threshold Signatures**

Nodes must collectively approve the current transaction to transfer assets between different blockchains.

Once the transaction is approved, assets can be transferred safely between blockchains.

👉 **Safety & Decentralization**

Galaxy's cross-chain safety relies on its decentralized nature and on its BFT (Byzantine Tault Tolerant) consensus algorithm.

This algorithm is optimized for low overload time and reduces the impact of faulty nodes during an asset transfer.
