# Wanchain Bridge Node Group

The Wanchain Bridge Node Group is a collection of 25 decentralised, permissionless bridge nodes that are rotated and re-elected monthly. Bridge nodes use a combination of Secure Multiparty Computation (sMPC) and Shamir’s Secret Sharing cryptography to execute cross-chain transactions, secure cross-chain assets, and transfer messages and arbitrary data between EVM and non-EVM blockchains. 

The Wanchain Bridge Node Group uses a 17-of-25 threshold, meaning a minimum of 17 bridge nodes must agree to validate and execute a cross-chain transaction.

The cross-chain component of all Wanchain products, including [WanBridge](https://docs.wanchain.org/products/wanbridge), [XFlows](https://docs.wanchain.org/products/xflows) and [XPort](https://docs.wanchain.org/products/xport), is secured by the Wanchain Bridge Node Group.

As a permissionless system, anyone can deploy a Wanchain Bridge node. Click [here](https://docs.wanchain.org/wanchain-bridge-nodes/deploy-a-bridge-node) to learn more.
