Developer Chris Guida has rebased Luke Dashjr's 2017 proof-of-work hard fork code onto Bitcoin Knots as a contingency; Dashjr has stated that a PoW change is the only option if BIP-110 fails. The Contingency Code Is Already WrittenDeveloper Chris Guida confirmed on August 4 that he has rebased Dashjr's 2017 PoW hard fork code onto current Bitcoin Knots. It does not apply to the PoW contingency, which is structurally a chain split by design. If the majority of hash power continues mining without signaling, those Knots nodes sit on a minority fork, receiving orphaned blocks. Node runners on Bitcoin Knots with BIP-110 enforcement enabled should treat the window around block 961,632 as operationally live.
