In this way, it provides a transparent and undetectable way of\nsending payments which commit to some data without adding extra data to the\nchain. It does, however, require some small amount of out-of-band communication.\n\nThis implements the neccessary parts of appendix A of the sidechains whitepaper,\nthough it is generally useful in many other cases.\n\nTo build\n========\n\nInstall https://github.com/bitcoin/secp256k1\n\nUse ldconfig so that the ld cache knows about the existence of secp256k1.\n","funding_links":[],"categories":["TODO scan for Android support in followings"],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FBlockstream%2Fcontracthashtool","html_url":"https://awesome.ecosyste.ms/projects/github.com%2FBlockstream%2Fcontracthashtool","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FBlockstream%2Fcontracthashtool/lists"}
