Feature Freeze & SIGHAST_NOINPUT ~ Bitcoin Op Tech #4
World Crypto Network
Bitcoin Optech #4 covers the July 23rd feature freeze for Bitcoin Core 0.17, rising transaction fees, and coin selection privacy. SIGHASH_NOINPUT (BIP 118) enables L2 channels but creates reuse risks—a signature can spend multiple outputs to the same address—so developers proposed renaming it to flag the danger.
