Bitcoin Cash price pressured as quantum-signature proposal nears review
Published on 11/13/2026 at 13:04 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWSBitcoin Cash faces a technical test
- Bitcoin Cash is trading below the previous UTC daily close as developers review a post-quantum signature proposal.
- CHIP-2026-06 could face a November 15 lock-in decision, but it remains under review and is not an activated network rule.
- CME Bitcoin Cash futures have expanded the regulated derivatives infrastructure available to institutional market participants.
Bitcoin Cash price is under pressure as the network's developers review a proposal aimed at supporting post-quantum and hybrid signatures. Kinzan quoted BCH at 218.62 US dollars at 06:26 UTC on November 13, 2026, down 4.30 percent over the previous 24 hours. The reading was below the 225.06 US dollar UTC daily close for November 12 reported by CoinGecko, a decline of 2.86 percent.
Quantum proposal remains unapproved
The technical focus is CHIP-2026-06, titled Post-Quantum and Hybrid Signatures. According to The Quantum Insider, the proposal introduces an OP_SIGHASH opcode that would expose a transaction's signature hash to the Bitcoin Cash virtual machine. It also outlines a dispatch mechanism for different signature schemes, including classical and post-quantum combinations.
Hybrid signatures would require both components to verify. The design is intended to provide a migration path while preserving existing address formats and wallet compatibility, according to the report. The proposal is under active discussion, with a potential lock-in date of November 15, 2026, and a targeted mainnet activation date of May 15, 2027. Neither date is a completed network event, and the proposal has not yet become an activated consensus rule.
Price context for BCH investors
The Bitcoin Cash price has weakened across recent sessions. Kinzan's data put the November 13 reading near the lower end of its 24-hour range of 214.65 to 229.20 US dollars and showed a 20-day volatility measure of 3.30 percent. Those figures describe market conditions at the cited observation time; they do not establish a cause for the decline.
Market access has also broadened. CME Group announced the first block trade in its Bitcoin Cash futures on October 20. The contracts give market participants a regulated venue for hedging and gaining derivatives exposure, but their introduction does not validate the technical proposal or determine the spot price.
What matters next
For investors, the key distinction is between review, lock-in and activation. A possible lock-in would mark progress in the development process, while any live-network change would require later implementation, testing and deployment. Until then, BCH remains exposed to broad crypto-market volatility as well as project-specific execution and adoption risks.
