Rootstock supports EVM-compatible smart contracts secured by the Bitcoin network, with tools for building scalable applications.
Lightning Network
The Lightning Network describes a system for scalable, instant Bitcoin and blockchain transactions.
About Lightning Network
The Lightning Network is described on its homepage as a system for fast Bitcoin and blockchain payments that do not wait for block confirmation times. Participants open a two-party payment channel by creating a ledger entry on the blockchain, then transact off-chain by updating balances. The most recent state can be broadcast to the blockchain to close the channel, and smart contracts are presented as the mechanism that enforces it.
The homepage says payments can be routed across a network of these channels, similar to how packets are routed on the internet. It states that the network depends on the underlying blockchain's technology and scripting language. Cross-chain swaps are described as possible only between chains that support the same cryptographic hash function. The linked technical paper is labeled as a draft, version 0.5.9.1.
Key features
- Two-party payment channels opened with a blockchain ledger entry
- Off-chain payment updates, with the latest state enforced by smart contracts
- Payment routing across a network of channels, similar to internet packet routing
- Atomic payments that either fully succeed or fail, enforced by time-locks
- Cross-chain atomic swaps between blockchains sharing a hash function
- Channel closure by broadcasting the most recent state to the blockchain
Best for: Developers and technically minded readers who want an overview of off-chain payment channels and routing built on Bitcoin.
Good for
- Describes payments that do not require waiting for block confirmation times
- States that off-chain settlement allows for exceptionally low fees
- Says cross-chain swaps can be made without third-party custodians
Watch out for
- Depends on the technology and scripting language of the underlying blockchain
- Cross-chain swaps require chains that support the same cryptographic hash function
- The linked technical paper is marked as a draft, version 0.5.9.1

Lightning Network FAQ
Is the Lightning Network built on Bitcoin?
The homepage describes the Lightning Network as using real Bitcoin and blockchain transactions and the native smart-contract scripting language of the underlying blockchain.
What happens if one party in a payment channel stops cooperating?
According to the homepage, either party can close the channel at any time by broadcasting the most recent version to the blockchain. The page says court involvement is needed only in the event of non-cooperation.
