StarkWare Reduces Quantum-Safe Bitcoin Transaction Cost to $66

A weeklong optimization challenge led by StarkWare has significantly lowered the computational expense of generating quantum-safe transaction proofs for the Bitcoin network. Participants utilized AI tools to improve efficiency, cutting the estimated cost by approximately 79% compared to previous benchmarks. While this progress makes quantum-resistant protocols more economically viable, researchers note that the solution has yet to be fully demonstrated in a live mined transaction.

INFERY / RESEARCH VERDICT

Rating

Watch

Fairly pricedMedium confidence

Despite a BUY_NO lean at a Yes estimate below the quoted Yes price, the action is WATCH, so no new entry is recommended. The cited news concerns quantum-resistant measures layered alongside, not replacing, Bitcoin's SHA-256 hashing under the resolution rules.

“Yes”Fair price range94–100¢

F1, dated September 22, 2026, discusses Bitcoin possibly going quantum-safe while Lightning privacy remains exposed, which concerns added privacy or post-quantum defenses rather than replacing SHA-256, and therefore does not by itself establish that Bitcoin stops using SHA-256 by the stated deadline; it only supports the view that no replacement has been shown to occur.
F2, dated September 23, 2026, describes PQLN, a post-quantum defense for the Lightning Network that the article says does not change Bitcoin's code and runs alongside existing nodes, so it does not establish a SHA-256 replacement and instead limits the case for Yes.

CURRENT MARKET

Will Bitcoin replace SHA-256 before 2027?

Current price 1.7¢

⚠Risk: Credible reporting or Bitcoin protocol changes showing SHA-256 is being retired or replaced before the deadline would undercut the BUY_NO lean and warrant reassessing the WATCH stance.

Next watch: Monitor the official market settlement at the stated deadline.
