We are also committed to the research and development of technical mechanisms to improve signaling in the bitcoin community, as well as to put in place communication tools, in order to more closely coordinate with ecosystem participants in the design, integration and deployment of safe solutions that increase bitcoin capacity



We welcome all companies, miners, developers and users to join us and help prepare bitcoin for the future
