Bitcoin Cash price remains under pressure while developers review a proposal that could add post-quantum and hybrid signature support to the network. Investing.com displayed BCH at 235.58 US dollars on November 11 at 13:47:25 Berlin time. The same page showed a seven-day decline of 14.1474 percent, while its displayed 24-hour volume was 195.26 million US dollars.

Proposal remains under review

According to The Quantum Insider, Bitcoin Cash contributor mainnet_pat has proposed CHIP-2026-06. The proposal introduces an OP_SIGHASH opcode intended to expose a transaction signature hash already calculated during signature verification. That would create a route for supporting different signature schemes, including post-quantum and hybrid combinations.

The proposed hybrid design would require both a conventional signature and a post-quantum signature to validate a transaction. This is a proposed migration path, not evidence that the Bitcoin Cash network has already become quantum-resistant. The Quantum Insider reported that the proposal was still open for review and that Bitcoin Cash Node developers had opened a merge request implementing the opcode.

November milestone is conditional

The proposal targets a potential lock-in on November 15, 2026, with mainnet activation targeted for May 15, 2027. Both dates remain conditional on the review and implementation process. For investors, the distinction matters: a proposal can affect expectations and development priorities, but it does not yet change the consensus rules or provide a deployed network feature.

Price context remains cautious

Investing.com's Bitcoin Cash page listed a market capitalization of 4.75 billion US dollars and a circulating supply of 20.11 million BCH. It also showed BCH 54.4686 percent lower over one year and 60.7342 percent lower year to date. Those figures describe the observed market context; they do not establish that the proposal caused the recent decline.

Against that backdrop, the Bitcoin Cash price is approaching a development deadline while the market remains volatile. The proposal may offer a longer-term technical theme, but its investment relevance depends on further review, implementation and eventual activation rather than on the announcement alone.
