Tether appoints independent director to Twenty One Capital board, restoring audit committee

The vacant audit committee seat on Twenty One Capital’s board has been filled by Tether International. The company designated an independent director that meets SEC and NYSE standards. Twenty One Capital’s (XXI) audit committee now has all the members it needs after Tether appointed a new independent director. Why was Twenty One Capital missing a director? The spot on Twenty One Capital’s (XXI) audit committee became empty after Tether purchased all 89.1 million shares SoftBank held in XXI for approximately $711 million on May 20. The deal gave Tether uncontested control as the majority shareholder of the Bitcoin treasury company, which holds more than 43,500 BTC. Once the deal closed , SoftBank’s representatives had to leave the board, including the one that served on the audit committee. Tether has now filled that spot with an independent director that it says meets the tough independence rules. The rules in question come from the Securities Exchange Act (Rule 10A-3) and the NYSE Listed Company Manual (Section 303A.02). These rules are designed to make sure audit committee members can oversee the company fairly without conflicts of interest. Paolo Ardoino, Tether’s CEO, said in the announcement that a great deal of rigor was put into finding the best candidate to deliver thorough and independent oversight. “The strength of the oversight needs to match the strength of the balance sheet,” Ardoino said, but Tether did not reveal the name of the new director in its announcement An audit committee is a group of board members who oversee a company’s financial reporting. The NYSE, requires listed firms to have at least three independent members on this committee. XXI is placed second among publicly traded corporate Bitcoin holders, trailing only Strategy (formerly MicroStrategy). Twenty One Capital places second among publicly listed Bitcoin treasury firms. Source: BitcoinTreasuries,net Independent board oversight is especially important now that Tether has consolidated its position. The stablecoin issuer already held voting control through XXI’s Class B shares and maintained approval authority over Bitcoin sales, mergers exceeding $1 million, and executive appointments. What are XXI’s next plans? Tether has proposed combining XXI with Jack Mallers’ Bitcoin payments company Strike and mining firm Elektron Energy. The three-way merger , first proposed in late April 2026, would create a vertically integrated Bitcoin business that includes treasury accumulation, payments, lending, and mining operations. Elektron manages about 50 exahashes per second (EH/s) of mining power. That is roughly 5% of the entire Bitcoin network. The platform has already mined more than 5,500 Bitcoins. Twenty One Capital launched in December 2025 through a SPAC merger with Cantor Equity Partners and trades on the NYSE under the ticker XXI. The merger has several hurdles surrounding its governance. For example, Jack Mallers currently serves as CEO of both Twenty One Capital (XXI) and Strike. The dual role is a conflict of interest that will require special review and a vote by minority shareholders. Raphael Zagury, the CEO of Elektron Energy, is a defendant in active lawsuits filed by Swan Bitcoin in California and the UK. Swan alleges that Zagury and other former executives conspired with Tether in 2024 to take over a mining joint venture. Tether has announced its intention to vote in favor of the mergers, but no final terms, closing timelines, or formal merger agreements have been signed or publicly released.

Ethereum Price Prediction: Will ETH Dump Toward $1K Next?

Ethereum has entered a decisive bearish phase after losing multiple high-timeframe support levels in a matter of days. The latest sell-off pushed ETH through a major confluence zone that had previously acted as support throughout the first half of the year, placing the market at a critical juncture where buyers must defend lower demand levels to prevent a deeper correction. Ethereum Price Analysis: The Weekly Chart The weekly chart shows a significant deterioration in market structure. After peaking near $5K, ETH established a series of lower highs beneath a descending trendline that has capped every major recovery attempt since late 2025. The recent rejection from this trendline reinforced bearish control and accelerated the latest downside move. More importantly, ETH has now broken below the major support area around $1.75K-$1.85K, a zone that previously acted as a key pivot during the March rebound. The breakdown confirms a bearish continuation pattern and shifts focus toward the next demand region around $1.45K-$1.55K. The current weekly candle is testing the upper boundary of that support zone, with price trading near $1.56K. A weekly close below this region would significantly increase the probability of an extension toward the broader demand area around $1.15K-$1.30K, which represents the next major historical support visible on the chart. For bulls to regain momentum, ETH would first need to reclaim the broken $1.75K-$1.85K region and eventually break above the descending trendline resistance. Until then, the broader structure remains bearish. ETH/USDT 4-Hour Chart The 4-hour chart highlights the severity of the recent sell-off. ETH broke down from a prolonged descending structure without establishing any meaningful support. The blue support zone between roughly $1.74K and $1.85K, which had previously acted as a major demand area and also aligns with the 0.5-0.618 Fib levels, failed to contain selling pressure and has now turned into resistance. ETH is currently testing the lower demand zone around $1.50K-$1.57K, where some reactive buying has emerged. However, the rebound remains limited and does not yet indicate a sustainable trend reversal. If this support area fails to hold, the next downside objective could emerge below $1.50K. On the other hand, any relief rally would likely encounter resistance around $1.74K-$1.85K, followed by the Fibonacci cluster between $1.88K and $1.92K. Sentiment Analysis The 3-month liquidation heatmap suggests that a substantial amount of downside liquidity has already been cleared during the latest cascade lower. As ETH plunged from above $2K toward $1.5K, most of the notable liquidation clusters beneath the market were swept, reducing the immediate magnetic effect from lower levels. Meanwhile, the most significant remaining liquidity concentrations are now positioned above the current price, particularly in the $1.7K-$1.9K region and extending toward the $2.4K-$2.5K area. This creates an interesting dynamic where the market lacks major nearby liquidity targets below spot while maintaining sizeable overhead liquidation pools. However, the absence of significant liquidity beneath price does not necessarily imply an immediate reversal. Instead, it suggests that ETH may enter a period of consolidation or corrective rebound before establishing its next directional move. If buyers fail to reclaim broken support levels, the market could still experience a deeper retracement driven by spot selling rather than liquidation hunting. For now, Ethereum remains under strong bearish pressure, but with most nearby downside liquidity already swept, traders should closely monitor whether the $1.45K-$1.55K support zone can stabilise price and trigger a relief recovery toward the newly formed resistance overhead.

Alephium Token Bridge Exploited for $815,000 in Guardian Key Attack

BitcoinWorld Alephium Token Bridge Exploited for $815,000 in Guardian Key Attack The Alephium token bridge has been exploited for approximately $815,000 after an attacker compromised three of the four guardian keys securing the cross-chain protocol, according to blockchain security firm Blockaid. The incident marks the latest in a series of attacks targeting cross-chain infrastructure in the decentralized finance ecosystem. How the Exploit Unfolded Blockaid reported that the attacker gained control of three out of four guardian keys responsible for signing verification messages on the bridge. This enabled the signing of a forged VAA (Verification of Asset Authenticity) message, which was then used to authorize the unauthorized transfer of assets out of the bridge’s liquidity pools. The total loss stands at roughly $815,000, though the exact breakdown of stolen tokens has not yet been fully disclosed. Guardian keys are a common security mechanism in cross-chain bridges, designed to require a threshold of signatures from trusted validators before transactions can be approved. In this case, the threshold was set at three out of four, meaning a single key compromise would not have been sufficient — but the attacker managed to breach three separate keys, bypassing the protocol’s intended security layer. Implications for Cross-Chain Security The Alephium incident highlights a persistent vulnerability in multi-signature bridge architectures: the risk of simultaneous key compromise. While threshold signatures are intended to distribute trust, the concentration of keys within a small validator set can create a single point of failure if multiple validators are compromised through similar attack vectors. Blockaid noted that the attack appears to have been carefully planned, targeting the specific key management infrastructure rather than exploiting a smart contract bug. This distinction is important because it shifts the focus from code auditing to operational security and key management practices. Market and Community Response Following the disclosure, the Alephium team confirmed they are investigating the incident and working with security firms to trace the stolen funds. The bridge has been temporarily paused to prevent further losses. Token prices for Alephium’s native ALPH token saw a moderate decline in the hours following the news, reflecting broader market concerns about cross-chain security. For users who have assets bridged to or from Alephium, the immediate risk appears contained to the bridge contract itself. However, the incident serves as a reminder that cross-chain bridges remain one of the most targeted attack surfaces in DeFi, with over $2 billion lost to bridge exploits since 2021 according to industry data. Conclusion The $815,000 Alephium bridge hack underscores the ongoing challenges in securing cross-chain infrastructure. While the absolute loss is relatively modest compared to larger DeFi exploits, the method — compromising multiple guardian keys — raises fundamental questions about key management and validator security in bridge architectures. Users and developers alike will be watching closely to see what remediation measures the Alephium team implements and whether the industry moves toward more robust key distribution models. FAQs Q1: What is a guardian key in a token bridge? A guardian key is a cryptographic key held by a trusted validator or entity that must sign off on transactions before they are executed on the bridge. A threshold of multiple guardian signatures is typically required to authorize a transfer, adding a layer of security against single-point failures. Q2: How did the attacker compromise three guardian keys? Blockaid has not disclosed the exact method, but common attack vectors include phishing, social engineering, exploiting weak key storage practices, or compromising the infrastructure where keys are stored. The investigation is ongoing. Q3: What should Alephium users do now? Users who have assets on the Alephium bridge should monitor official announcements from the Alephium team. The bridge has been paused, which prevents further withdrawals or deposits. Users should not interact with the bridge contract until it is declared safe. No action is needed for assets held directly on the Alephium mainnet. This post Alephium Token Bridge Exploited for $815,000 in Guardian Key Attack first appeared on BitcoinWorld .

Zcash’s Orchard Shock: Why Supply Verification Became ZEC’s Main Catalyst

Zcash’s privacy promise rests on advanced cryptography. But in late May 2026, the project faced a shock: a “soundness” vulnerability in the Orchard circuit called its most important asset—verifiable integrity—into question. Overnight, the conversation around ZEC pivoted from fees and throughput to a single issue: can total supply be trusted? This article cuts through the noise. If you hold ZEC, operate an exchange desk , or build with shielded transactions, you will find a practical playbook to navigate updates, assess supply-verification options, and avoid common mistakes while the ecosystem shores up trust . AspectWhat to KnowWhat happenedA critical soundness bug was discovered in Zcash’s Orchard zero-knowledge circuit and responsibly disclosed on May 29, 2026 by researcher Taylor Hornby, engaged by Shielded Labs ( Zcash Foundation ).Emergency responseA two-step response: a soft fork that disabled Orchard at height 3,363,426 (early June 2, 2026 UTC), then NU6.2 (Zebra 5.0.0) re-enabled Orchard at block 3,364,600 on June 3, 2026 (00:05 EDT) ( Zcash Foundation ).Adoption backdropShielded holdings had just surged to roughly 5.0M ZEC (~30% of ~16.7M circulating), with Orchard holding ~4.2M ZEC (~25.4%) in late May 2026 ( ZcashTracker ).Market reactionPublic disclosure and fixes coincided with a sharp drawdown; reports cited ~30–40% declines and multi‑billion market-cap evaporation around June 5, 2026 ( CoinTelegraph ).Main riskConfidence in supply integrity. Even if no exploit occurred, the mere possibility elevated “auditability” from niche concern to core investment criterion.Near-term taskGet upgraded, verify operational dependencies, and decide policies for shielded flow until community-level mitigations mature.Longer-term trackProposals include formal verification of Orchard and a new shielded pool with a “turnstile” for public supply checks ( KuCoin ). Core Concepts Zcash supports both transparent addresses and private, “shielded” addresses. Shielded transactions rely on zero-knowledge proofs to show that assets are conserved without revealing amounts or participants. In this model, a circuit’s soundness is paramount: if a bug lets someone create value from nothing, the ledger’s supply could be inflated without easy detection. In late May 2026, an independent researcher working with Shielded Labs found precisely such a risk in the Orchard circuit and disclosed it to Zcash engineers. The project executed an emergency soft fork and then the NU6.2 hard fork to address the issue and re-enable Orchard after patching ( Zcash Foundation ). This incident landed amid strong shielded adoption. By late May 2026, about 5.0 million ZEC—roughly 30% of circulating supply—sat in shielded pools, with Orchard alone holding ~4.2 million ZEC (~25.4%). That depth underscores why supply verification is now the overriding narrative for ZEC, not just a cryptography footnote ( ZcashTracker ). Glossary: the moving parts Orchard — Zcash’s latest shielded pool/circuit enabling private transfers with improved performance and UX. Soundness — A zero-knowledge property that ensures proofs cannot assert false statements (e.g., minting coins from thin air). Soft fork — A backward-compatible rule change; in this case, used to disable Orchard transactions swiftly. NU6.2 (Zebra 5.0.0) — The emergency network upgrade and release that re-enabled Orchard after patching. Turnstile accounting — A proposed design where funds must transition through a checkpoint, enabling public supply integrity checks without revealing transaction details. Step-by-Step Playbook Upgrade your stack immediately. Wallets, nodes, and services should move to releases compatible with the NU6.2 patch (e.g., Zebra 5.0.0 or later) before processing new shielded flow. Freeze-and-review policy for shielded deposits. Exchanges and OTC desks can apply enhanced monitoring or temporary holds on large shielded deposits until post-patch behavior is well characterized. Use viewing keys and address segmentation. For operational safety, separate treasury, hot, and cold flows, and use viewing keys to monitor shielded balances without de-shielding. Reconcile with transparent rails. Where possible, settle internal accounting in transparent addresses during the near term, then batch into shielded pools once procedures are validated. Track chain health signals. Monitor client diversity, block propagation, mempool behavior, and shielded pool deltas across blocks after the re-enable height to spot anomalies early. Document assumptions for audit. If you are a custodian or fund, write down your operational assumptions about supply integrity and how you would detect inconsistencies; review weekly until conditions normalize. Plan for alternative liquidity. Map out ZEC liquidity venues that support transparent withdrawals and keep emergency counterparties on file if shielded rails slow temporarily. Why “Supply Verification” Became the ZEC Catalyst Privacy coins walk a tightrope: strong confidentiality makes public auditing inherently harder. In Zcash, shielded pools hide amounts, so most observers rely on circuit soundness and protocol accounting to be confident that no excess ZEC exists. When a soundness issue surfaces—even if swiftly patched—the perceived possibility of undetected inflation forces markets to reassess risk. That is exactly what unfolded. Following public disclosure and emergency upgrades, multiple outlets reported that ZEC fell roughly 30–40% with billions shaved off market value in early June 2026 ( CoinTelegraph ). The market’s message was blunt: supply integrity is the meta-driver of ZEC’s cost of capital. Everything else—fees, throughput, even UX—sits downstream of that trust anchor. Crucially, the incident arrived at a time of real shielded usage: about 30% of circulating supply was in shielded pools, roughly 25% in Orchard specifically, just before disclosure ( ZcashTracker ). That structural adoption amplifies both the upside of privacy and the downside if verifiability is in doubt. Pro tip: Take pre- and post-upgrade snapshots of shielded pool totals from reputable trackers and your own node. You are not “proving” global supply, but you are establishing a baseline to detect outliers quickly. Where the Project Goes Next: Options on the Table Several mitigation paths are under discussion. Early signals from ecosystem participants include formal verification of the Orchard circuit, growing security staff, and a new shielded pool design with a turnstile that enables public supply checks even under strong privacy ( KuCoin ). Below is a high-level comparison of the main approaches, each with material trade-offs. OptionHow it WorksProsConsBest Use CaseStatus quo (post-NU6.2 Orchard)Patched Orchard circuit continues; community emphasizes bug bounty, audits, and monitoring.Fastest path; minimal UX change; leverages existing wallets and infra.Relies on continued circuit correctness; public can’t easily check supply end-to-end.Short-term continuity while deeper mitigations are specified.Formal verificationMathematically prove core parts of the circuit and protocol properties.Raises assurance beyond audits; institutional confidence boost.Time- and resource-intensive; scope limits may leave edges unproven.Mid- to long-term credibility investment.Turnstile-enabled shielded poolIntroduce a checkpoint that allows aggregate supply reconciliation without exposing user data.Balances privacy with public supply checks; addresses central investor concern.Requires new design and migration plan; possible friction for users and devs.Long-term path to durable market trust.Operational restrictions (policy)Exchanges/custodians throttle or require transparent rails for high-value flows.Reduces exposure quickly; straightforward to implement.Hurts shielded liquidity and UX; fragments the market.Stopgap control for risk desks during uncertainty. Stakeholder Scenarios: Making Decisions Without the Hype Long-only holders. If your thesis is privacy adoption, decide whether your conviction depends on unbroken, continuous verifiability or whether you can tolerate periods where the community’s assurance relies on engineering responses and future design changes. Position sizing should reflect that tolerance for ambiguity. Exchanges and OTC desks. After the emergency fix, re-enable shielded deposits only with upgraded infrastructure and document additional screening. Consider a tiered policy: small shielded deposits auto-clear; larger ones require extra checks or time-bound delays until chain behavior appears stable post-patch. Wallet and app developers. Communicate upgrade status clearly in-app. Offer viewing key tooling and migration paths so users can self-monitor. If a turnstile design is adopted later, build UI affordances early for a seamless transition. Institutional allocators. Request written security postures and timelines from core teams. If you need public supply checks to underwrite a position, evaluate whether a turnstile roadmap and formal verification plan meet your governance thresholds. Open-source contributors. This is a moment to expand testing harnesses, fuzzers, and circuit-level proof tooling. If you specialize in formal methods, there is leverage here: even partial proofs can raise confidence.

Pre-NU6.2 software may mishandle Orchard transactions or expose you to consensus mismatches. Assuming “no exploit” equals “no risk.” The market prices the possibility of silent inflation. Policies should reflect that, not just incident retrospectives. Overreliance on single trackers. Cross-check shielded pool data between multiple sources and your own node to avoid skew from API errors. Impersonation and phishing. Expect fake “urgent wallet updates.” Only download from official repositories and verify signatures. Liquidity traps. If venues throttle shielded deposits, spreads can widen. Test small amounts before committing size. Conflating privacy with opacity in governance. Supply verifiability is separate from user privacy; avoid narratives that pit them as mutually exclusive without nuance.

Frequently Asked Questions What exactly was the Orchard bug? A researcher engaged by Shielded Labs identified a “soundness” flaw in the Orchard zero-knowledge circuit—meaning, in principle, it could allow proofs that assert something false. The issue was responsibly disclosed on May 29, 2026, leading to an emergency response by Zcash engineers ( Zcash Foundation ). How did the network respond so quickly? The community executed a two-step plan: first, a soft fork disabled Orchard at block 3,363,426 in early June 2, 2026 (UTC), then NU6.2 (Zebra 5.0.0) re-enabled Orchard at block 3,364,600 on June 3, 2026 (00:05 EDT) with the fix live ( Zcash Foundation ). Was ZEC’s supply actually inflated? There is no public confirmation that an exploit occurred. However, markets price the risk that it could have, and that’s why supply verification rose to the top of the agenda. Stakeholders are focusing on mitigations that restore confidence whether or not an exploit happened. Why did the price fall so sharply? Security and supply integrity are primary valuation anchors in privacy coins. Reports cited ~30–40% declines around June 5, 2026, following disclosure and emergency patches ( CoinTelegraph ). Uncertainty around verifiability tends to widen risk premia. What are the leading fixes to rebuild trust? Discussions include formal mathematical verification of Orchard, expanding cryptography/security staffing, and a new shielded pool with a turnstile to enable public supply checks without sacrificing privacy ( KuCoin ). As a user, what should I do now? Upgrade your wallet and node software to NU6.2-compatible releases, confirm your balances with viewing keys, and test small transactions first. If you rely on exchanges, check their current policies on shielded deposits and withdrawals. Do shielded users lose privacy with a turnstile? A well-designed turnstile aims to allow aggregate supply checks without revealing who sent what to whom. The details matter, but the intent is to keep user-level privacy while enabling public audit of total supply. Disclaimer: This article is provided for informational purposes only.

Quantum Computing’s Real Threat to Crypto: Financial Infrastructure, Not Bitcoin Wallets, Expert Warns

BitcoinWorld Quantum Computing’s Real Threat to Crypto: Financial Infrastructure, Not Bitcoin Wallets, Expert Warns As quantum computing advances, much of the cryptocurrency industry’s security anxiety has focused on a single, visceral fear: the possibility that a sufficiently powerful quantum machine could crack the private keys of Bitcoin wallets, draining funds from individual users. But according to Andrew Gault, CEO of the decentralized networking firm ZeroTier, this focus may be misplaced. The more immediate and systemic danger, he argues, lies in the financial infrastructure that underpins the entire digital asset ecosystem. The Real Target: Authentication and Payment Systems In a detailed analysis shared with industry peers, Gault outlined that the primary risk from quantum computing is not the direct compromise of consumer Bitcoin wallets but the broader authentication and payment infrastructure used by financial institutions, cryptocurrency exchanges, and custodians. These systems rely on cryptographic protocols that could be rendered obsolete by quantum algorithms, particularly Shor’s algorithm, which is designed to factor large integers and compute discrete logarithms—the mathematical foundations of many public-key cryptosystems. “The narrative has been heavily focused on individual wallet security, but that’s a distraction from the larger, more fragile target,” Gault said. “The financial plumbing—how banks, exchanges, and custodians authenticate transactions and communicate with each other—is where the real exposure lies.” ‘Harvest Now, Decrypt Later’: A Growing Data Stockpile Gault highlighted a particularly insidious tactic already underway: “Harvest Now, Decrypt Later” (HNDL) attacks. In this scenario, adversaries are already intercepting and storing encrypted data, including inter-institutional payment records, authentication messages, and digital signatures. While these communications cannot be decrypted today, the attackers are betting that future quantum computers will be able to break the encryption retroactively. This data stockpile represents a ticking time bomb for the financial sector. Sensitive transaction histories, proprietary trading strategies, and authentication credentials could all be exposed years after they were transmitted, undermining the confidentiality and trust that the financial system depends on. Digital Asset Infrastructure at Risk The threat extends well beyond traditional banking. Gault pointed out that digital asset infrastructure—including exchange API authentication, cross-chain bridge proofs, and custodian signature systems—is equally vulnerable. These systems often use the same cryptographic primitives (such as ECDSA and RSA) that quantum computers are expected to break. For example, a quantum computer could forge the signatures used to validate transactions on a cross-chain bridge, potentially draining liquidity pools or minting unbacked tokens. Similarly, an attacker could compromise the API keys used by trading bots and institutional clients, gaining unauthorized access to exchange accounts. “The entire stack of digital asset operations is built on assumptions about cryptographic security that may not hold in a post-quantum world,” Gault warned. “We need to start thinking about upgrading these systems now, not after the first major breach.” Why This Matters Now The timeline for quantum computing’s arrival remains uncertain, but major technology companies and national governments are investing heavily in quantum research. IBM, Google, and China’s quantum initiatives have all demonstrated steady progress in increasing qubit counts and reducing error rates. While a cryptographically relevant quantum computer is likely still years away, the HNDL threat means that data being transmitted today could be compromised retroactively. For the cryptocurrency industry, this creates a dual imperative. First, exchanges, custodians, and DeFi protocols must begin transitioning to quantum-resistant cryptographic algorithms, such as lattice-based cryptography or hash-based signatures. Second, users and institutions should assume that all current encrypted communications could eventually be decrypted, and act accordingly—particularly for long-lived secrets like private keys or master seed phrases. Conclusion Andrew Gault’s analysis reframes the quantum computing threat from a narrow concern about individual wallet security to a systemic risk facing the entire financial infrastructure. While Bitcoin’s core protocol may be more resilient than often assumed—due to its use of SHA-256 for mining and the ability to upgrade signature schemes—the surrounding ecosystem of exchanges, bridges, and custodians is far more exposed. The industry faces a critical window to adopt quantum-safe standards before the data stockpiled today becomes the vulnerability of tomorrow. FAQs Q1: Can quantum computers currently break Bitcoin wallet private keys? No. Current quantum computers are far too small and error-prone to break the elliptic curve cryptography (secp256k1) used by Bitcoin wallets. A cryptographically relevant quantum computer—estimated to require millions of stable qubits—is likely years away. However, the threat is considered credible long-term. Q2: What is a ‘Harvest Now, Decrypt Later’ attack? It is a strategy where attackers intercept and store encrypted data today, with the intention of decrypting it later once quantum computers become powerful enough. This poses a particular risk to financial communications, authentication messages, and digital signatures that have long-term sensitivity. Q3: What can crypto exchanges and custodians do to prepare? They should begin auditing their cryptographic dependencies, prioritize the adoption of post-quantum cryptographic standards (such as those being developed by NIST), implement crypto-agility to allow rapid algorithm swaps, and educate users about the risks of long-term data exposure. Some are already experimenting with lattice-based signatures and hybrid key exchange protocols.
