Ark: A UTXO-based Transaction Batching Protocol

Ark is a novel scaling protocol for Bitcoin that enables offchain transaction execution while allowing users to keep full custody of their funds. This is made possible through the introduction of Virtual UTXOs (VTXOs), which allow users to transact offchain while retaining the ability to unilaterally exit to the Bitcoin mainchain. Coordinated by an operator who batches user activity into on-chain commitments, Ark achieves high transaction throughput with a minimal on-chain footprint, offering a simple and accessible scaling solution for Bitcoin, and can accommodate layer-2 constructions that would be too inefficient or costly to execute on the Bitcoin mainchain.

Bark

Bark is a Rust implementation of the Ark protocol on bitcoin, led by second.tech. It includes an Ark wallet called "bark" and an Ark server called "captaind".

Arkade

Arkade is a Bitcoin-native virtual execution layer that is built on the Ark protocol foundation. It enables programmable money through offchain coordination while preserving Bitcoin's security guarantees. Arkade virtualizes Bitcoin's transaction layer to enable instant, parallel execution without requiring protocol changes.

A new era for Bitcoin Development

Bitcoin’s app stack has matured fast: payments, programmability, execution, indexing, and contract layers now exist as production-ready building blocks.
