bitcoin's real innovation wasn't just fixed supply. it was making rules expensive to violate. proof of work turns time, energy, and hardware into a wall against arbitrary human change. that's why pos always slides back toward politics: when validation is tied to existing wealth, power compounds socially first and technically second. this is why i find ckb interesting. not as an " ethereum killer\ clown story, but as bitcoin philosophy taken further into programmable state. the cell model feels like utxo thinking grown up properly: explicit state, explicit ownership, explicit verification. add riscv and you get a vm that doesn't feel like financial theater. it feels like engineering. #bitcoin #ckb #pow #riscv
