what's Kasar Labs?

Kasar Labs is a Starknet engineering and research laboratory specializing in blockchain infrastructure, particularly for scalability solutions like zero-knowledge rollups. They developed and open-sourced a Bitcoin data-availability (DA) adapter in Rust, enabling Starknet-based rollups (via Sovereign SDK or Madara) to leverage Bitcoin's security and finality without protocol changes to Bitcoin itself. This facilitates ZK rollups on Bitcoin, enhancing scalability and privacy, in collaboration with projects like Chainway and Taproot Wizards.

Kasar Labs released Barknet with Taproot Wizards as a sovereign rollup implementation.
