The Ark protocol for Bitcoin layer two was developed by #BurakKeceli, a self-taught Bitcoin developer and researcher. He proposed Ark in May 2023 as a solution to the scalability problems of the Bitcoin network. Ark is a layer-2 protocol that uses a different approach to scaling than other layer-2 solutions like Lightning. It does this by using intermediaries called Ark Service Providers (#ASPs) to provide liquidity and coordinate CoinJoin sessions.

Ark is still under development, but it has the potential to significantly improve the speed, security, and scalability of Bitcoin transactions. It is a promising new layer-2 protocol that could help to make Bitcoin more widely adopted.

Here are some of the key features of the #Arkprotocol:

* It uses a different approach to scaling than other layer-2 solutions, which could make it more scalable and efficient.

* It uses intermediaries called ASPs to provide liquidity and coordinate CoinJoin sessions, which could make it easier for users to send and receive funds.

* It is designed to be more privacy-preserving than other layer-2 solutions.

* It is still under development, but it has the potential to be a major breakthrough in Bitcoin scalability.

I hope this helps!
