About bitcoin taproot mutual satisfaction clause

Book mastering bitcoin 3rd edition, page 179.

enter image description here

In MAST and with scriptless multisignatures, a mutual satisfaction clause is easy to design. We simply make one of the top leaves of the script tree a scriptless multi signature between all interested parties. We already saw a complex contract between several parties with a simple mutual satisfaction clause in Figure 7-7. We could make that more optimized by switching from scripted multisignature to scriptless multisignature.

Bitcoin Mining May Support The Ruble Responding to a question at a press conference, Nabiullina said it is “probably difficult to quantify” mining’s influence “because a significant part of mining is still in a gray area.” Still, she added that mining is “indeed one of the additional factors contributing to the strong ruble exchange rate.” As Russian business news portal for RBC reported , her remarks come as Russian officials increasingly frame mining and crypto flows as macro-relevant, not just a niche tech or energy story. Earlier, Maxim Oreshkin, deputy head of the presidential administration, said ruble forecasts have been thrown off by the underestimation of financial flows tied to mining and cryptocurrency. In his view, the s...
