How Fiber Network Works

Off-chain Payment Channels
An off-chain payment channel allows two parties to lock funds on-chain, conduct unlimited instant transactions off-chain, and settle the final balance on-chain when the channel is closed.

Frequently Asked
Questions

The Fiber network is a protocol designed to enhance the functionality, programmability, and connectivity of the Lightning Network. Built on the CKB blockchain, it is fully compatible with the Lightning Network at the protocol design level, creating a seamless connection between Bitcoin and CKB on Layer 2. This integration enables the smooth flow of transactions across both networks, making micropayments faster and cost-efficient. Tokens on the Fiber network are highly programmable, supporting the transfer of various assets including stablecoins. The Fiber network provides Bitcoin and Lightning Network users with secure off-chain payments, offering low transaction fees, high programmability, and enhanced interoperability.
The Lightning Network is a second-layer protocol built on top of the Bitcoin blockchain that enables fast, low-cost transactions by creating off-chain payment channels between users.
A Payment Channel Network is a system of interconnected payment channels that allows users to make transactions through multiple intermediary nodes without needing a direct channel to the recipient.
