# Blockchain Network

THXNET. Blockchain Network is built and customized upon the Polkadot Substrate Framework and FRAME pallets as its foundation. We firmly believes in the concept of Web3 as a network of networks and has chosen to leverage the strengths of established technologies to support this vision.

A Rootchain and its Leafchains communicate via XCM protocol which is a messaging format and language used to communicate between consensus systems.

Collators in a Leafchain gather the changes from the most recent block. They then send a packed summary of these changes to the Validators of the Rootchain, who help finalizing the block.

For more details, please refer to [Polkadot doc](https://wiki.polkadot.network/docs/learn-parachains).
