SEC’s Crypto Advocate Says Blockchain Code Is Protected By The Constitution
A federal securities regulator is drawing a line between writing blockchain code and being responsible for how that code gets used — and the distinction could reshape how the government treats software developers in the decentralized finance space. Broader Regulatory Shift Behind The Remarks Hester Peirce, a commissioner at the US Securities and Exchange Commission, made the case Tuesday at the IC3 Blockchain Camp at Princeton University that publishing open-source blockchain software is a protected activity under the First Amendment. She argued that developers who release DeFi code should not be automatically classified as securities intermediaries just because other people use what they built. LATEST: SEC Commissioner Hester Peirce says securities rules shouldn’t apply to blockchains themselves, noting “blockchains are used to do many things other than transact in securities.” pic.twitter.com/hztB7r72ap — CoinMarketCap (@CoinMarketCap) June 4, 2026 Legal liability, she said, should fall on those who actually engage in unlawful conduct — not on the people who wrote the underlying tools. Peirce’s remarks fit into a wider rethinking underway at the SEC since Chair Paul Atkins took the helm. The agency has been pulling back from what Atkins has described as regulation by enforcement, with its Crypto Task Force now reviewing how existing securities laws apply to digital assets and decentralized systems. Peirce, a long-standing voice for clearer rules in the crypto space, has been central to that push. Rules Built For A Different World She pointed to the SEC’s rulebook as evidence of the problem. The agency’s regulations were designed around intermediaries — brokers, dealers, exchanges, clearinghouses, transfer agents, investment advisers, and investment companies. Peirce questioned whether those same rules make sense when applied to distributed blockchain networks that exist for purposes well beyond securities transactions. Her comments came weeks after SEC staff issued separate guidance addressing broker-dealer registration requirements for certain user interfaces. That guidance indicated some front-end websites and software platforms that provide access to decentralized protocols may not qualify as brokers under the traditional legal definition — a signal that the agency is rethinking how far its existing categories can stretch. Digital Assets As Long-Term Priority The SEC has also signaled that crypto and blockchain technology will remain a focus for years ahead. In its draft Strategic Plan through fiscal 2030, the agency described blockchain and crypto assets as technologies with the potential to reshape America’s financial infrastructure. Taken together, the staff guidance, the strategic plan, and Peirce’s speech at Princeton paint a picture of an agency trying to redraw boundaries that were never clearly set.

Crypto Expert Says Something Bad Is Coming For Bitcoin, What To Expect
A crypto market expert has shared a grim Bitcoin (BTC) forecast, warning that a major price crash could be on the horizon for the leading cryptocurrency. The analyst noted that Bitcoin’s recent break below a critical support level may have opened the door for a deeper decline that could potentially send its price to much lower levels. He acknowledged that the market remains firmly in a bearish phase and expects more choppy price action before the anticipated breakdown occurs. Why Bitcoin Could Face A Bad Crash Soon A crypto analyst known as Tony Research has issued a warning to Bitcoin traders and investors, declaring “something bad is coming.” In an X post on June 2, he revealed that just a few hours earlier, Bitcoin had lost a key support level after testing and failing to hold the $70,000 zone . A few days before that breakdown, the analyst also noted that he had forewarned that such a move could occur. Now, Tony Research has outlined what the broader market should expect moving forward. To provide more clarity and context, he also gave a detailed breakdown of the events and price movements that occurred before and during BTC’s latest support breakdown. Before losing this key support, Tony Research noted that Bitcoin had undergone a deep price correction from the 0.618 Fibonacci level and the 200-day Moving Average (MA). He explained that the cryptocurrency had broken a long-term ascending channel that had been forming since the beginning of the year. His accompanying chart shows that BTC had been trading within a narrow range inside this channel, breaking above it only once when it briefly surpassed the $80,000 level . That rebound, however, was short-lived, as the price quickly resumed its decline, leading to the current lows. Tony Research added that Bitcoin is now trading below the Ichimoku Cloud after breaking the lower boundary of the ascending channel. He warned that this is a major bearish signal , potentially triggering Bitcoin’s largest price crash yet and putting investors and bullish traders at serious risk of losses. What Comes Next For The BTC Price In his analysis, Tony Research outlined the next moves Bitcoin investors should watch out for. First, he expects a bounce from $67,000 to around $74,000, signaling a short-term relief rally . After that rebound, Tony Research predicts BTC could plunge toward new lows below $60,000 . His chart specifically points to key downside targets ranging between $56,000 and $54,000. He noted that once this decline runs its course, the bear trap may be complete, potentially marking a final bottom for the cryptocurrency. The analyst also warned that expecting a bull market at this stage would be “foolish.” He said investors should anticipate multiple short-term rebounds even as Bitcoin continues its downtrend.

Crypto Billionaires Rally Behind Nigel Farage As Political Stakes Rise
Reform UK’s fundraising total climbed sixfold compared to the same period last year, when the party pulled in just $2 million in crypto and other donations. In the first quarter of 2026, it raised $12.5 million — more than any other British political party. A Party Funded By Crypto Money Two donors drove most of that haul. Christopher Harborne, who holds a stake in stablecoin issuer Tether, gave $4 million. Ben Delo, co-founder of crypto exchange BitMEX, gave $5.4 million — his first-ever donation to Reform UK . Together, their contributions account for $9.4 million of the party’s Q1 total, based on data released Thursday by the UK Electoral Commission. Labour and the Conservatives each raised around $5.4 million in the same quarter. Reform’s fundraising not only outpaced them both but exceeded the combined total from either of the two traditional parties. Farage’s Pitch To The Crypto World Nigel Farage has made his position on crypto clear. Reform UK was the first British political party to accept Bitcoin donations. Farage is a British politician who has been the leader of the Reform UK since 2024. Farage has also called for capital gains tax on crypto to be slashed from 24% to 10% and wants the Bank of England to build a Bitcoin reserve — proposals that have drawn attention from the industry on both sides of the Atlantic. It’s not just Nigel Farage taking millions from the super-rich. His Reform Party is doing it too. Reform pocketed £7 million from two crypto billionaires in the first three months of 2026 We need to kick ALL big-money out of politics. Our democracy should not be for sale! — Richard Burgon MP (@RichardBurgon) June 4, 2026 In the US, crypto-backed political action committees have been spending heavily on midterm election primaries, backing candidates who went on to win. The pattern mirrors what is now unfolding in Britain, where industry money is flowing toward politicians seen as sympathetic to the sector. A Donor Under Scrutiny Harborne’s relationship with Farage goes beyond party donations . He separately gave Farage a personal gift of $6.7 million, which is now the subject of a parliamentary standards inquiry into whether it should have been properly declared. Farage has maintained he had no obligation to register the money, saying it was received before he became a member of parliament and was intended to cover personal security costs. He later said the gift was tied to his role in the Brexit campaign. The Bigger Picture The Electoral Commission data shows total political donations across all parties more than doubled compared with Q1 of last year. Reform’s rise accounts for a significant share of that increase. Harborne’s contributions to the party now total $20 million over the past 12 months, making him one of the largest individual political donors in British politics today.

BREAKING – Michael Saylor Tries To Cool Bitcoin’s Internal Rivalries — But Can He?
Michael Saylor said Bitcoin has moved far beyond its early life as a niche protest and now reaches individuals, companies, banks, capital markets, and governments. In a new paper posted on X, he grouped the Bitcoin world into four camps and argued that the split reflects growth, not collapse. Four Camps, One Network The four labels are Bitcoin Maximalists, Bitcoin Capitalists, Bitcoin Technologists, and Bitcoin Fundamentalists. According to the paper, they all see value in Bitcoin, but they disagree on how far it should stretch, how fast it should change, and how tightly it should tie itself to the financial system. Saylor cast Maximalists as people who see Bitcoin as the main digital monetary network, a form of sound money, and a shield against inflation and weak currencies. https://t.co/yeG4PgpjEq — Michael Saylor (@saylor) June 5, 2026 He also said this group gives Bitcoin moral clarity, while still leaving open the question of how the network fits with banks, public companies, and governments. Bitcoin Capitalists, in his view, push in the other direction and want the asset embedded in portfolios, balance sheets, credit products, custody systems, and market infrastructure. Saylor described them as the group most comfortable with corporate treasuries, institutional custody, and financial tools built around Bitcoin rather than just on top of it. Protocol Pressure Points The technologist camp, Saylor said, wants Bitcoin to keep improving on issues like scalability, privacy, security, wallet design, usability, custody, and even future threats such as quantum computing. He warned that upgrades carry risk, because Bitcoin’s base layer holds value in part because users trust it not to change carelessly. He drew a hard line around the Fundamentalists, who focus on self-custody, personal nodes, decentralization, immutability, and censorship resistance. Their concern is that banks, governments, custodians, leverage, and financial engineering could push Bitcoin away from the purpose that made it worth defending in the first place. That wider argument lands while Strategy , the company Saylor leads as executive chairman, is under fresh market pressure after a rare Bitcoin sale drew attention last week. Reports said the firm sold 32 BTC for about $2.5 million, its first Bitcoin sale since 2022, as Bitcoin traded near $60,000 and ETF outflows weighed on sentiment. A New Phase For Bitcoin Saylor’s paper frames the split as a normal stage in Bitcoin’s growth, not a sign of failure. His message was that Bitcoin can keep its base layer intact while allowing markets, custody services, and new financial products to grow around it. Featured image from Gemini, chart from TradingView

Hoskinson Denies Cardano Exit Rumors: ‘I’m Not Leaving’
Cardano founder Charles Hoskinson rejected speculation that he is leaving the ecosystem, saying in a June 4 livestream that he is stepping back from public-facing communication but not resigning from Cardano. The comments came after his brief “taking a break” post on X triggered concern across the community and inquiries from journalists Hoskinson opened the livestream by directly addressing the rumors. “I wanted to make a quick video to remind everybody that I am okay,” he said. “I’m not suicidal. I’m not leaving the ecosystem or resigning from Cardano and running around.” The clarification followed a wave of speculation after Hoskinson signaled he would take time away from social media. He said the reaction reflected a broader problem with the communication environment around Cardano, especially on X, where he argued productive engagement has become nearly impossible. Hoskinson Says Online Toxicity Has Become Unsustainable Much of Hoskinson’s livestream focused on what he described as a hostile social media environment. He cited an analysis of roughly 130 replies to his recent comments, saying nearly one-third were hostile, abusive, or profanity-laden and that some showed signs of coordinated targeting. “Every tweet, about 30% of all replies is hostile, negative, and it’s categorized this way,” Hoskinson said. “It’s really impossible to meaningfully engage and want to be there in those types of platforms with people. So I wanted to leave last year and I thought for sure I’d be out.” Hoskinson said X remains difficult to abandon because it is still one of the few platforms where crypto-native information moves quickly and directly. Still, he argued that the psychological cost of staying in that environment had become too high, adding that he does not want to be in a communication medium where personal attacks dominate a significant share of engagement. He also drew a sharp distinction between his continued work on Cardano-related technology and the public expectation that he should be responsible for ADA’s market performance . “What I’m not passionate about is making the price of ADA go up so that speculators can dump it and go on to the next thing,” Hoskinson said. “I’m just not. It’s never been my passion. I’ve never accepted that role. I’ve never once told you that that is my job.” Hoskinson said he remains focused on work including RealFi, making Bitcoin programmable, proofs, privacy, Midnight , and broader research. But he said the community has to decide whether Cardano is primarily about science, philosophy, and real-world impact, or whether it is increasingly defined by price frustration. Cardano Founder Calls For New Roadmap Hoskinson described what he called “the tale of two Cardanos”: one in which the protocol, engineering base, decentralization, and research stack have advanced significantly since 2021, and another in which market performance has led critics to label the project a failure. “We’re massively ahead of where we were in 2021,” he said. “Massively. We’ve done things that we could only have dreamed of when I started the project. Leios testnet is starting June 23rd. I think when you look at it from a price appreciation, we’re in the toilet. We’re at 18 cents. It’s a dead and failed project.” That gap, he argued, has produced a “cognitive dissonance” that Cardano’s community must resolve. Hoskinson said the ecosystem needs to leave X as its primary venue for discussion, rethink incentives for builders, change parts of its management culture, and develop a new roadmap that gives participants a shared destination. He was particularly critical of the Cardano Foundation, arguing that ADA holders lack meaningful accountability mechanisms over its board, priorities, and staffing. He called the structure “the worst mistake” of his career, contrasting it with Input Output, where he said the community can vote against proposals. Hoskinson said he will take time away from public videos, interviews, X, and other social channels while continuing to work on Midnight. He said he intends to reflect, recover, and later propose ideas for Cardano’s future, ranging from incremental reforms to more radical changes. “I could certainly be part of it, but you know what my red lines are,” he said. “I have to be treated with respect and dignity and I am only going to live in channels that enforce that.” At press time, ADA traded at $0.1589.

There’s An FOMC Meeting Scheduled This Month, But Will The Fed Decision Affect Bitcoin?
The Federal Open Market Committee (FOMC) meeting is held eight times a year, and just like with any financial market, the outcome of each meeting has implications for the likes of Bitcoin. The announcement that follows the FOMC meeting reveals whether interest rates have been changed or if they’re staying the same. Now, another FOMC meeting has rolled around, and the market is already speculating on what could happen next. The Next FOMC And The Expectations The next FOMC meeting is scheduled for June 16 and 17, after which the Fed Chairman, Jerome Powell, is expected to give a speech outlining the outcome of the meeting. The last FOMC meeting held on April 28-29 saw the Fed holding interest rates at the same level, and the expectations seem to be following the same trajectory once again. The CME’s FedWatch tool tracks sentiment across the market and plots the graph showing the odds of a change in interest rates or the Fed keeping interest rates the same. According to the tool, the market is still expecting that the Fed will keep interest rates at the same level. Current interest rates lie at 3.5-3.75% (or 350-370 basis points), and the tool shows that there is a 99.4% chance that the Fed will keep interest rates the same. The remaining 6% swings in favor of the Fed actually hiking interest rates to 3.75-4.00%, or 370-400 basis points. Whereas the odds of the Fed dropping interest rates to 3.25-3.50% lies at 0%. What Happens To Bitcoin Depending On What The Fed Does Depending on what the Fed announces after the FOMC meeting , the Bitcoin price tends to react very differently. If the odds are right and the interest rates are kept the same, then the bitcoin price is expected to keep following the same trajectory it’s on, as there would not be any incentive for investors to change their stance at this point. In the case that the Fed ends up hiking interest rates, then it could be very bearish for the market. This is because higher interest rates lead investors to take less risk, reducing the liquidity flowing into Bitcoin . It also tends to trigger sell-offs, as investors rush to reduce their risk of losing money. On the other end of this is the Fed actually lowering interest rates. This is the most bullish scenario for Bitcoin as lower interest rates encourage investments in risk assets. In such a case, the Bitcoin price is likely to rise as investors move into the digital asset.

US Senators Press Bank Regulators For ‘Fair’ Crypto Capital Rules
A group of Senate Republicans is pressing bank regulators to build on recent regulatory progress by creating a clearer capital framework for crypto activities and asset treatment. US Senators Call For Clear Crypto Capital Rules On Thursday, Senate Banking Subcommittee on Digital Assets Chair Cynthia Lummis and Senators Dan Sullivan, Bill Hagerty, Bernie Moreno, Ted Budd, and Jon Husted shared a recent letter urging key financial agencies to move toward “clear and fair” capital rules for banks engaged in crypto asset activities. The letter, addressed to Federal Reserve Vice Chair for Supervision Miki Bowman, Federal Deposit Insurance Corporation (FDIC) Chairman Travis Hill, and Comptroller of the Currency Jonathan Gould, criticized the international Basel Committee on Bank Supervision’s capital standards, which gave “the most punitive classification in the capital framework” to crypto assets. Notably, the standard assigned a 1,250% risk weight, used to determine how much a bank must hold against a certain asset, on crypto assets. To the senators, “This classification was not derived from a calibrated assessment of the actual risk profile of digital assets. Instead, it “appears to be a blanket penalty assigned by asset category as a de facto ban on banks holding this asset class, in direct tension with a technology-neutral approach” that agencies like the Office of the Comptroller of the Currency (OCC) and the FDIC have disclosed over the past year. The lawmakers applauded the regulatory agencies for their recent interagency guidance on tokenized securities, which clarified the capital treatment of these assets. In March, the FDIC, the OCC, and the Federal Reserve jointly said that tokenized securities should generally receive the same capital treatment as their non-tokenized counterparts, affirming that capital treatment should reflect the risk characteristics of the underlying asset, not the technology used to record ownership. “That principle should apply consistently—including to other digital assets,” the letter stated. Citing this position and recent progress on the crypto market structure bill, which would expand banks’ ability to engage in balance-sheet crypto asset activities, the senators urged the FDIC, OCC, and Federal Reserve to begin developing a new capital framework for such activities. Top Regulators Shift To ‘Risk-Based’ Supervision The senators’ call for new crypto capital rules came as the three regulators testified before the House Financial Services Committee on Thursday morning, updating lawmakers on their broader effort to revisit and ease several bank rules implemented after the 2008 financial crisis. In prepared remarks, the FDIC chair noted that the agency is implementing several changes to reform its approach to a more “effective and efficient” supervisory framework that continues to support the safety of individual institutions and the broader system. Hill stated that strong capital standards play a critical role in ensuring a resilient banking system , while driving economic growth and supporting their customers. Regarding crypto assets, he stated that the agency has issued several proposed rules to regulate and oversee subsidiaries of FDIC-supervised Insured depository institutions (IDIs) approved to issue payment stablecoins under the GENIUS Act. Similarly, the OCC Chief affirmed that it is “returning to risk-based supervision rooted in law and emphasizing examiner judgment, not arbitrary checklists,” and reviewing past supervisory criticisms and enforcement actions. “Our job is to facilitate, not stymie, responsible innovation,” Gould said, adding that “Our banking system will only remain relevant and trusted if it resists pressures to deny access based on political or religious beliefs or lawful business activity. We have made considerable progress in reviewing the activities of the largest national banks and are investigating complaints of alleged debanking, consistent with the President’s executive order.”

Bitcoin Miner Inflows Hit Highest Level Since February Crash: Capitulation Or Distribution?
Bitcoin has experienced significant selling pressure following a 16% drop since Monday — a decline that has shaken the confidence built during the recovery from the April lows and forced participants to reassess where genuine structural support exists in the current market structure. Against that backdrop, CryptoQuant data has identified a specific development in the miner flow data that adds a supply-side dimension to the current weakness that experienced on-chain analysts will recognize immediately. On June 2, Bitcoin miner inflows to Binance reached 24,716 BTC — the highest reading since February 5, when the metric recorded 23,151 BTC. The latest spike surpassed that February high by approximately 1,565 BTC, or roughly 6.8%, making it one of the strongest miner-to-exchange flow events recorded this year. This marks only the second time in nearly four months that miner flows to Binance have crossed the 20,000 BTC threshold — a level that has historically attracted market attention when breached. The concentration of the move is the structural detail that makes the reading more significant than a broad market-wide increase would be. The spike was not distributed evenly across exchanges — it landed specifically on Binance, establishing the world’s largest crypto exchange as the primary venue where miner-linked Bitcoin supply is reappearing. When supply concentrates on a single venue at this scale, that venue’s order book dynamics become the critical variable for how the market absorbs or fails to absorb what has arrived. 24716 BTC From Miners on One Day The CryptoQuant analysis applies the honest framework that prevents the miner inflow spike from being automatically read as a sell signal. Large miner deposits to exchanges do not confirm immediate selling intent — the motivations behind a 24,716 BTC transfer to Binance can include hedging against price risk, operational liquidity management, internal rebalancing between custody solutions, or preparation for selling that may or may not materialize in the near term. What the transfer does confirm is a state change. Bitcoin that was held in miner custody — removed from exchange order books and unavailable for immediate market sale — has now moved to a venue where it can be converted to other assets within seconds. The distance between that supply and the sell side has collapsed. Whether miners exercise that proximity immediately or hold the coins in exchange wallets without selling, the supply overhang exists, and the market must account for it. The forward signal the report identifies is duration-dependent. Miner inflows remaining elevated across multiple sessions would confirm a sustained distribution or sell-side pressure pattern — the behavioral signature of miners making a deliberate decision to reduce holdings at current price levels. A spike that fades quickly would suggest a one-day liquidity event rather than the beginning of a broader trend. Bitcoin’s price reaction in the sessions immediately following the June 2 spike is the data point that will determine which interpretation the market ultimately assigns to the largest miner-to-exchange flow event of the year. Bitcoin Tests the 200-Week Moving Average After Violent Breakdown Bitcoin has suffered a major technical deterioration on the weekly timeframe, with price collapsing more than 15% this week and falling from the $74,000 region to nearly $62,000. The move has erased the entire May recovery and pushed BTC back into the critical support area that defined the February cycle low. The most important development on this chart is Bitcoin’s return to the $61,000-$63,000 support zone. This region marked the bottom of the February capitulation event and triggered the rally that eventually carried BTC above $80,000. Bulls are once again attempting to defend the same level, making it one of the most significant areas on the chart. The breakdown below the $65,000 and $73,000 resistance zones confirms that sellers remain firmly in control. Both former support areas have now been lost and are likely to act as overhead resistance on any recovery attempt. The sharp rejection from the $80,000 region also established a clear lower high relative to the late-2025 peak, reinforcing the bearish structure. However, a critical technical factor is beginning to emerge. Bitcoin is now trading directly on top of the rising 200-week moving average near $62,000. Historically, this moving average has acted as one of the strongest long-term support levels in Bitcoin’s history and has often marked periods of extreme value during major corrections. If buyers successfully defend the 200-week moving average and the February low region, Bitcoin could attempt to build a base for a recovery. Failure to hold this area would expose the psychologically important $60,000 level and potentially open the door to a deeper correction toward the mid-$50,000 range.

Zcash Bug Could Have Minted Unlimited ZEC Undetected
A critical vulnerability in Zcash’s Orchard shielded pool could have allowed an attacker to create an unlimited amount of counterfeit ZEC without detection, according to a new disclosure from Zooko Wilcox, Jason McGee and security researcher Taylor Hornby. The flaw was discovered on May 29, remediated through an emergency ecosystem response completed by June 2, and has now triggered a broader debate over how Zcash can prove supply integrity in a privacy-preserving system. Orchard Flaw Puts Zcash Supply Integrity Under Scrutiny The vulnerability was found by Hornby , an experienced security engineer hired by Shielded Labs in April 2026 to conduct ongoing security research on the Zcash protocol. According to the disclosure, the mandate was straightforward: find protocol-level weaknesses before adversaries did. Hornby began reviewing Zcash with a combination of traditional security research and newer AI-assisted auditing methods. The timing was unusually compressed. Shortly after Anthropic released its Opus 4.8 model on May 28, Hornby used it in a targeted review of the Orchard circuit. One day later, he found a critical counterfeiting flaw and disclosed it to Zcash Open Development Lab, or ZODL , whose engineers coordinated the emergency response with other ecosystem participants. “The vulnerability could have been exploited to undetectably create an unlimited amount of counterfeit ZEC within Orchard,” the Shielded Labs post said . “Because of the privacy properties of Orchard, there is no way to cryptographically prove whether the vulnerability was exploited before it was remediated. However, a network upgrade can be deployed to protect users and prove the integrity of the Zcash supply.” The disclosure states that the bug was “real and exploitable.” Hornby, with the help of Opus 4.8, wrote a complete exploit and tested it in a local regtest environment, where it generated unlimited counterfeit ZEC that could not be detected. The authors said that had the same tool been run on mainnet, it would have generated unlimited, undetectable counterfeit ZEC in Hornby’s mainnet wallet. Technically, the issue involved an under-constrained element of the Orchard circuit. That made it possible to feed arbitrary false inputs into an elliptic curve multiplication while still passing the multiplication check. The vulnerability existed from Orchard’s activation in May 2022 until the emergency fix was deployed on June 1, 2026. That timeline is central to the concern. In a transparent ledger, supply irregularities can generally be audited by inspecting public balances and transaction values. Orchard is different by design: it hides amounts and transaction history. That privacy model means the system depends heavily on the correctness of the circuit rules that define valid shielded transactions. Josh Swihart, founder and CEO of Zcash Open Development Lab, the team behind the creation and launch of Zcash and builder of the Zodl wallet, framed the issue in those terms in a separate post. “A shielded Zcash transaction includes a proof that it followed the protocol’s rules, as defined in the rulebook (the circuit) that defines what constitutes a valid transaction. The Orchard vulnerability was in one of the rules, written loosely enough that it would accept false information and still pass. As a result, the engine could be convinced that a fake transaction was valid.” Swihart added that the flaw was not in Zcash’s underlying cryptography or the proof engine itself, but in the handwritten rules. In his words, “This was a flaw in the handwritten rules, not in the underlying cryptography or the engine that creates proofs.” Shielded Labs said prior exploitation appears unlikely, while emphasizing that users should not be asked to rely on that assessment alone. The authors pointed to several reasons for their view: the flaw had evaded years of scrutiny by leading cryptographers, Hornby was specifically hired to find such vulnerabilities, and the response window after discovery was sharply narrowed by the speed of ZODL and the broader Zcash ecosystem. “The discovery was not accidental—it was the result of a deliberate effort to identify vulnerabilities of this kind before malicious actors could,” the post said. “Taylor is one of the most skilled people in the world at this. He used the most recent AI tools, available only to white-hat security researchers, along with a sophisticated custom-built AI harness and prompts, and worked hard to outrace the attackers. We think he probably succeeded.” Still, the authors acknowledged the unresolved cryptographic uncertainty. Because of Orchard’s privacy properties and the nature of the bug, they said there is no definitive way to prove solely through cryptography whether the vulnerability was exploited before the fix. Shielded Labs Eyes New Pool And Formal Verification To address that, Shielded Labs is exploring a proposed network upgrade with other Zcash developers. The plan would deploy a new shielded pool and enforce turnstile accounting on coins moving from the existing Orchard pool, with the goal of allowing anyone to verify the integrity of the Zcash supply and prove the non-existence of counterfeit ZEC in Orchard. A follow-up post is expected next week with more details, including tradeoffs and implementation mechanics. Any major upgrade would still need community support and the standard governance process before activation. Swihart said a second Orchard pool could, in principle, be targeted for NU7 at the end of July, though he did not take a fixed position on whether that path should be pursued. He argued that the larger issue is preventing this class of failure from recurring, with formal verification as the strongest answer. “Formal verification fixes this,” Swihart wrote. “A mathematical proof can be constructed to reduce the parts humans must review to a concise, readable statement of the rules. A computer then checks the entire rulebook to ensure it matches. AI tools can now do the work of writing these proofs.” Shielded Labs said it is already accelerating proactive security work with Hornby and Anthropic, initiating a project to formally verify the Orchard circuit, and opening searches for a Head of Security and a Cryptographer. The episode leaves Zcash with a difficult but clear path: repair the trust assumptions around Orchard, prove supply integrity where possible, and move future shielded design closer to machine-checked guarantees rather than human-reviewed complexity. Over the past 24 hours, ZEC has fallen nearly 45% amid the uncertainty. At press time, it was trading at $337.
