# How does Janction select and use different DAs?

Janction will comprehensively evaluate different DAs from multiple aspects, including security, technology stack maturity, scalability, and cost. Bitcoin has the highest network security at present, but its script does not have Turing completeness, and its functionality as a DA is poor. Therefore, we will focus on the technical development of the Bitcoin ecosystem. Ethereum is a mature DA, and we will prioritize considering and supporting Ethereum. However, the fees and throughput of Ethereum may become a bottleneck for our development. Therefore, we are also investigating other high-throughput and low-cost DA projects, such as Celestia, Avail, and EigenDA.
