This provides a prime-order group that can be efficiently implemented inside a Bulletproof.\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdalek-cryptography%2Fdoppio","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdalek-cryptography%2Fdoppio","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdalek-cryptography%2Fdoppio/lists"}
