JUST IN: Second has launched Bark on Bitcoin mainnet, bringing the Ark protocol to production and aiming to make self-custodial Bitcoin as simple to use as custodial apps.
Bark is designed to solve one of Bitcoin’s biggest challenges: self-custody without sacrificing user experience.
While on-chain transactions can be slow and expensive during periods of congestion, and traditional Lightning wallets often require users to manage channels and liquidity, Ark takes a different approach.
The protocol uses a client-server architecture where the server handles payment routing across Ark, Lightning, and on-chain rails, while users remain in control of their bitcoin and retain an emergency exit if the server becomes unavailable or malicious.
The launch marks one of the most significant real-world deployments of Ark to date, as developers continue searching for ways to make self-custodial Bitcoin accessible to mainstream users without relying on traditional custodians.
