Bitcoin Cash proposal nears review as price holds near UTC close

Bitcoin Cash is approaching a review milestone for a proposed security upgrade, while its market price remains close to the previous UTC daily close. The Bitcoin Cash price was 235.58 US dollars at 13:47:25 Berlin time on November 11, 2026, according to Investing.com.

Proposal remains under review

The focus is CHIP-2026-06, a Cash Improvement Proposal that introduces the OP_SIGHASH opcode and a mechanism for supporting multiple signature schemes. The proposal is designed to support post-quantum and hybrid signatures while retaining compatibility with existing address formats and wallet tooling.

The Quantum Insider reported on November 5 that the proposal was under active discussion and implementation review. A potential lock-in date is November 15, 2026, and the article gives May 15, 2027, as the targeted mainnet activation date. Both dates remain conditional on the review and approval process; the proposal is not an activated consensus rule.

What the proposed change does

CHIP-2026-06 would expose the transaction signature hash through OP_SIGHASH, reducing the need for contracts to reconstruct that calculation manually. It also outlines a signature dispatch framework that could accommodate current secp256k1 signatures alongside post-quantum schemes. Hybrid keys would require both the classical and post-quantum components to verify, creating a possible migration path rather than an immediate replacement for existing signatures.

The technical significance is therefore longer term. Developers, wallet providers and node implementers would still need to assess implementation details, supported algorithms and the outcome of the CHIP process before any network-wide effect could follow.

Price remains below recent levels

Investing.com showed a 24-hour volume of 195.26 million US dollars, a market capitalization of 4.75 billion US dollars and a circulating supply of 20.11 million BCH on the same page. For the daily comparison required here, Best Crypto Checker lists a November 10, 2026, price of 235.44 US dollars. The current reading is therefore 0.06 percent higher than that UTC daily reference, based on unrounded values. This modest move does not by itself establish a market reaction to the proposal.

Investors monitoring BCH should distinguish the approaching review deadline from an approved upgrade. Until the proposal advances through the stated process, its potential security and application benefits remain prospective. Further Bitcoin Cash coverage is available on the Bitcoin Cash topic page.
