Bitcoin Cash price in focus as quantum-signature proposal nears review deadline
Published on 11/10/2026 at 13:01 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWSWhat BCH investors should watch
- Bitcoin Cash developers are reviewing CHIP-2026-06, a proposal for post-quantum and hybrid signatures.
- The proposal could reach a lock-in decision on November 15, 2026, with activation targeted for May 15, 2027.
- CME Group began trading Bitcoin Cash futures on October 20, while a dated market table recorded a USD 239.24 BCH close for November 9.
Bitcoin Cash price is being watched alongside a proposed protocol change that could add a path toward post-quantum and hybrid signatures. The proposal is not active consensus code: it remains under review ahead of a possible November 15, 2026, lock-in date.
Proposal remains under review
The Quantum Insider reported on November 5 that Bitcoin Cash contributor mainnet_pat had formalized CHIP-2026-06. The proposal introduces an OP_SIGHASH opcode that would expose the transaction hash already calculated during signature verification.
The design would support a registry of signature schemes, including existing secp256k1 signatures and potential post-quantum algorithms. Hybrid keys would require both classical and post-quantum checks to succeed. The proposal is intended to preserve existing address formats and wallet compatibility, but the reported target of May 15, 2027, for mainnet activation remains conditional on the review and implementation process.
Institutional access expands
A separate market-structure development came on October 20. CME Group said FalconX and GSR executed the first block trade in its new Bitcoin Cash futures. The contracts provide a regulated derivatives venue for managing BCH exposure, but their introduction does not by itself establish a direction for the token's spot market.
Price data needs a date check
The Investing.com page read for this report displayed BCH at USD 266.23, with a 24-hour volume of USD 213.50 million, market capitalization of USD 5.34 billion and a rank of 17. The page labeled the quote real time but did not show a calendar date for its displayed time, so the figure is a page reading rather than a verified November 10 tick.
For a dated UTC reference, Kinzan's market page records a November 9 daily close of USD 239.24 and describes BCH at USD 239.08 at 21:53 UTC that day. These figures should not be combined into a percentage move against the undated Investing.com reading. The relevant investor question is therefore whether the protocol proposal advances and whether futures liquidity develops, rather than whether a single cross-source quote implies causation.
