Seems like this might be possible, at least it should be. Can this be done now? With BitVM? Is there an interface?
Alice has 1.0 BTC. She wants to give it to her son as inheritance when she passes (or maybe just give it in the future "with a warm hand" before dying). Say her heir is Harry. Harry has his #bitcoin wallet address all ready to receive the inheritance. Alice simply wants that BTC to move to Harry's wallet if and when she dies (or at block number XXXXXX).
How can she make this happen?
