Zcash Patches Consensus Bug in Zebra 4.5.1 as ZEC Price Diverges Across Reports
The Zcash Foundation released Zebra 4.5.1 to fix a sigop counting flaw in P2SH parsing that could split Zebra nodes from zcashd. Coverage disagrees sharply on ZEC's price, with one outlet citing $572.12 and another reporting a market move above $1,300.

The Consensus Patch
The Zcash Foundation shipped Zebra 4.5.1, an emergency update to its Rust-based node client, to address a consensus vulnerability tracked as GHSA-2prc-cj5x-4443. According to the Foundation's forum advisory, the bug is a statistical error in counting signature operations in P2SH scripts. That error could let Zebra accept blocks that the legacy zcashd implementation rejects, creating conditions for a network fork. The Foundation said it "strongly recommend[s] all Zebra node operators upgrade to 4.5.1 as soon as possible."
The 4.5.1 release is a hotfix for a flaw the Foundation says was not fully addressed in 4.5.0. PANews reported that 4.5.0 already included fixes for the same sigop issue, a defect in NU5 block verification cache logic, a risk of crash from transparent address balance overflow, and several crash and resource exhaustion issues in RPC and memory pool handling.
A Pattern of Emergency Releases
The 4.5.1 patch is the third Zebra release in a short window. Zebra 4.4.0 arrived in early May and fixed five security vulnerabilities, three of them consensus-critical. One of those allowed a block-discovery halt that could be triggered "with just one malicious connection," and another was a sigop miscount that let a block pass Zebra while failing on zcashd. Zebra 4.5.0 followed on May 29, and 4.5.1 came immediately after. Taken together, the sequence points to recurring consensus-layer fragility in the client, not a single isolated defect.
Conflicting Price Reports
Sources disagree on where ZEC is trading. Crypto.news put ZEC at about $572.12 with a market capitalization near $9.48 billion, and described a sharp run-up from the $235 to $240 range that ZEC consolidated in late March. In April, crypto.news also reported intraday rallies to $330 and $383 tied to record shielded supply.
CryptoPotato, in a separate market wrap, said ZEC rose about 13 to 14% in a day to "well over $1,300" after the US midterm elections. The two figures cannot both describe the same spot price on the same day. The difference may reflect different reporting dates, different data providers, or an error in one of the reports, and neither source reconciles it. Readers should check a primary price feed before relying on either number.
Market Backdrop
CryptoPotato framed the broader session around a Binance hack that it said exposed $6.3 billion, the largest hack by USD value in crypto history, which pushed Bitcoin from about $81,000 to a multi-week low near $76,100. Bitcoin then recovered to about $78,500 after the US midterm elections, with a market capitalization of $1.570 trillion on CoinMarketCap and dominance near 60%. CryptoPotato reported that most altcoins turned green in that rebound, and that Ethereum traded above $2,300. The $6.3 billion figure is reported by a single outlet in this material and was not corroborated by the crypto.news piece.
Outlook
Crypto.news described a wide range over the next three to six months, with roughly $400 as downside support and $800 as upside if privacy and zk-SNARK interest returns, and a bearish stress scenario toward $256. Those levels are analyst scenarios, not forecasts, and they rest on a price base that the sources do not agree on. Any further consensus-level disclosures from the Foundation would be the main near-term variable to watch.
Why It Matters
For Traders
The sources disagree on ZEC's spot price by more than double, so verify a live feed before acting on any level cited here.
For Investors
Repeated emergency consensus patches within weeks raise a durable question about client maturity and network stability for Zcash.
For Builders
Operators running Zebra should upgrade to 4.5.1 now, and teams relying on P2SH sigop accounting should review their own validation logic.
