SECURITY

Zcash patches a vulnerability that allowed undetectable coin counterfeiting, triggering an emergency hard fork and a governance crisis.

cryptobriefing decrypt decrypt theblock

What happened. A critical flaw in Zcash’s shielded transaction protocol was disclosed and patched via an emergency hard fork. The bug allowed an attacker to mint ZEC undetectably, exploiting the very privacy guarantees that define the network. ZEC’s price cratered on the news, wiping billions from its market cap, and Cypherpunk Technologies, a listed Zcash treasury company, saw its shares fall more than 40%.

Why it matters. The incident exposes a fundamental tension in privacy coin design: the same cryptographic opacity that shields users also shields any inflation or counterfeiting from on-chain verification. Experts are flagging that the attack class is not unique to Zcash, and that banks and other institutions building on zero-knowledge infrastructure face analogous audit blind spots. The governance fallout compounds the damage, with questions about how long the flaw was known and who approved the hard fork.

The catch. Cypherpunk is publicly insisting it will press ahead with accumulating 5% of ZEC supply, calling the sell-off FUD, but its credibility depends heavily on whether the governance process around the patch holds up to scrutiny. The emergency decision-making structure that pushed through the fix is now drawing its own criticism as overly centralised for a project whose identity is built on trustless privacy.

Markets

Bitcoin breaks below $60,000 for the first time since 2024. A stronger-than-expected US jobs print pushed risk assets lower across the board, with Bitcoin falling more than 50% from its October peak. Memecoins DOGE and SHIB dropped roughly 9%, amplifying the broader drawdown. The Zcash vulnerability disclosure added a confidence shock on top of the macro pressure. decrypt coindesk

Bitcoin treasury companies collectively shed $62 billion in value this week. Strategy shares hit a four-month low and its STRC preferred stock came under pressure alongside the BTC slide. Bitmine and other leveraged treasury vehicles saw paper gains evaporate, with Hyperliquid’s treasury standing as the lone exception in profit across the cohort. cryptobriefing decrypt theblock

BlackRock picked up $47 million in Bitcoin into the dip. The purchase came against a backdrop of broad market fear, reinforcing the institutional pattern of treating sharp corrections as accumulation windows. ETF flow data for the broader session is still pending, but the directional signal from the world’s largest asset manager will be watched closely. cryptobriefing

ADA trades at four-year lows below $0.20 as social activity spikes. The divergence between rising chatter and falling price is a familiar pattern at local bottoms, though it can equally mark capitulation. Cardano has now given back essentially all gains accumulated during the 2024 bull cycle. coindesk

Securitize clears its SEC registration statement, opening the path to NYSE listing. The BlackRock-backed tokenisation firm will trade as SECZ following a SPAC merger that requires a shareholder vote expected later this month. The listing would make Securitize the first major real-world asset tokenisation platform to trade on a major US exchange. coindesk theblock

BitMine prices preferred shares with a 9.5% dividend in an upsized offering. Tom Lee’s Ethereum treasury vehicle is lifting the Strategy preferred-share playbook and applying it to ETH accumulation. The offering is designed to fund further ETH purchases, adding another leveraged corporate bet on ether at a notably weak moment for prices. decrypt

Visa and Brale are exploring private stablecoin settlement via SBC on the Canton Network. The pair are testing whether Canton’s privacy-preserving infrastructure can support institutional stablecoin flows without exposing counterparty data on a public ledger. It is an early signal that enterprise settlement is moving toward purpose-built privacy rails rather than public chains. cryptobriefing

Crypto Council for Innovation launches a vault-focused regulatory coalition. The coalition is targeting DeFi vaults specifically, pushing for a defined regulatory framework around deposit-and-yield mechanisms that have so far operated in a grey zone. With stablecoin and market-structure legislation advancing, vaults are the next contested surface area. theblock

TrustedVolumes, a 1inch Fusion resolver, lost $6.7 million in an exploit. 1inch confirmed its core protocols and user funds were untouched; the breach was isolated to TrustedVolumes as an independent resolver operating within the Fusion ecosystem. A bug bounty has been floated. cointelegraph_defi

AI tooling surfaced a critical flaw in a major crypto network, with warnings the class of vulnerability extends to banks. The disclosure underlines that AI-assisted code auditing is now a real threat-surface accelerant, capable of finding flaws at a pace human auditors cannot match. Security researchers are urging financial institutions building on similar cryptographic primitives to audit urgently. coindesk

On the Hill

Seven crypto tax bills circulated ahead of a House Ways and Means Committee hearing on Tuesday. The package covers de minimis reporting exemptions for small transactions, broker definitions, and treatment of staking rewards. It is the first time congressional leadership has formally scheduled crypto tax legislation for deliberation, marking a shift from informal discussion to active drafting. decrypt cointelegraph_regulation theblock

Illinois is one signature away from a 0.2% crypto transaction tax becoming state law. The levy, embedded in the FY2027 budget passed by Illinois lawmakers, places collection responsibility on registered brokers rather than end users. It is the most concrete state-level crypto tax action in the current cycle and will be watched as a template or cautionary tale by other states. cointelegraph_regulation
