Ark is a layer-two protocol for making off-chain Bitcoin transactions. Initially published on the bitcoin-dev mailing list as TBDXXX by Burak, is has since been named Ark and the protocol design has advanced significantly.

The Ark protocol is a payments system where people can make Bitcoin transactions at very low cost and without requiring any setup. The Ark model very closely resembles the UTXO model, which is a key differentiator with Lightning.

Ark is a scaling solution for Bitcoin that involves moving transactions off-chain. Ark executes transactions outside of the Bitcoin main chain but posts transaction data back on-chain in a compressed format. Ark servers bundle multiple off-chain transactions into large batches before submitting them to the Bitcoin blockchain. This method spreads fixed costs across multiple transactions in each batch, significantly reducing fees for end-users.
