Tezos Protocol’s Tallinn Upgrade Completes Successfully, Slashing Block Times and Boosting Network Efficiency

Following a successful on-chain governance process, the Tezos protocol has been upgraded to "Tallinn," its 20th forkless evolution. This upgrade significantly reduces Layer-1 block times to 6 seconds, accelerating finality and lowering latency. These improvements complement the network's EVM-compatible Layer-2, Etherlink, which now achieves finality in just 12 seconds. Tallinn also enhances security and staking rewards by enabling all bakers to attest to every block through the use of BLS cryptographic signatures. Furthermore, it introduces an "Address Indexing Registry" that can boost storage efficiency by up to 100x for applications, reducing costs and increasing potential throughput. This upgrade underscores Tezos' commitment to continuous, decentralized innovation, improving speed, security, and enterprise usefulness without network disruptions.

$40 Million+ US Govt Crypto Heist Leads To Contractor Exec’s Son: ZachXBT

On-chain investigator ZachXBT alleges that over $40 million was stolen from US government cryptocurrency seizure wallets, tracing the theft to John Daghita, also known as "Lick." The investigation suggests a connection to Daghita’s father, who owns Command Services & Support (CMDSS), a company with an active US government contract to assist the US Marshals Service in managing seized crypto assets. ZachXBT’s findings are based on recorded Telegram chats and wallet transactions, including a public dispute where Daghita displayed control over wallets containing millions in crypto. The funds are linked to earlier government seizures, including assets from the Bitfinex hack. Following the allegations, CMDSS’s online presence was deactivated. The incident has raised significant concerns among commentators, calling it a national security crisis and urging legislative action.

Over 300K US Government Bitcoin at Risk After Alleged Insider Theft Exposes Custody Failures

A contractor's son allegedly stole over $40 million from U.S. government-seized cryptocurrency wallets, according to blockchain investigator ZachXBT. The theft is linked to insider access at Command Services & Support (CMDSS), a firm contracted by the U.S. Marshals Service to manage seized digital assets. The incident raises serious concerns about the security of billions in confiscated Bitcoin from cases like Silk Road and the Bitfinex hack. Evidence emerged from a leaked Telegram recording showing the suspect moving funds from government-linked wallets. While some funds were returned, approximately $700,000 remains missing. The breach highlights vulnerabilities in the government's custody systems, including reliance on basic tracking methods and potential insider threats. This incident may undermine confidence in the U.S. government's ability to safeguard and manage seized crypto assets.

SwapNet Exploit Drains $17M, Exposes DeFi Approval Risks

A significant security breach occurred at DEX aggregator SwapNet, resulting in a loss of approximately $16.8 million. The exploit was first identified by security firm PeckShield. The attacker swapped $10.5 million in USDC for Ether on Base network and bridged the funds to Ethereum. The vulnerability stemmed from users disabling the "One-Time Approval" feature designed to restrict token permissions. By doing so, they inadvertently granted direct and persistent approvals to underlying contracts, including SwapNet’s router, which the attacker exploited. Matcha Meta, the meta-DEX aggregator through which SwapNet was accessed, clarified that the issue did not originate from its core system but from this user configuration choice. SwapNet paused its contracts to mitigate further damage and investigate the incident. Users were urged to revoke approvals granted outside the One-Time Approval framework, especially for SwapNet’s router. The event underscores a critical DeFi trade-off: one-time approvals enhance security but add friction, while unlimited approvals improve usability but create persistent risk if a platform is compromised. This incident is part of a broader pattern of exploits targeting unverified code and standing approvals, highlighting ongoing risks in DeFi’s interconnected ecosystem. SwapNet has not yet released a technical post-mortem or confirmed user compensation.

Ethereum Builds Team To Guard Against Quantum Threat

The Ethereum Foundation has formed a new Post-Quantum (PQ) team, led by Thomas Coratger, to prepare the network for potential quantum computing threats. The team, which includes cryptographers and engineers, is transitioning from research to practical testing on devnets. Their work involves developing quantum-safe tools and testing new algorithms while ensuring current transactions remain unaffected. A $2 million prize pool has been announced to encourage improvements in quantum-resistant solutions, including $1 million dedicated to enhancing the Poseidon hash function. Multi-client devnets are already active, with biweekly research sessions and a Post-Quantum Day planned for March 2026. Although the quantum risk is not immediate, Ethereum is proactively addressing it to ensure a smoother transition and better protect users and the network. Community reactions are mixed, with some praising the initiative while others express concerns about implementation and wallet upgrades.

Bringing Web3 to 'Daily Life': Zakk Details the 'Next Phase' of OKX Web3

At the OKX "New Year's Eve Dinner" event on January 24, 2026, Zakk, Head of OKX Wallet, outlined the next phase of OKX Web3’s strategy: making crypto part of everyday life. The vision is built on three core principles: security and self-custody as the foundation, user experience as the bridge, and ecosystem infrastructure as the driving force. Zakk emphasized that a "superior Web3 experience" requires uncompromising security—such as protection against address poisoning scams—coupled with simplicity for users. OKX Wallet supports ~140 blockchains and aggregates ~500 DEXs, using smart routing to improve speed and pricing. Three key products were highlighted: - **Smart Account**: Integrates AA, MPC, and seedless technology with TEE-secured private keys, enabling advanced self-custody trading features like limit orders. - **CeDeFi**: A new wallet blending CEX and DEX functionalities, targeting new users with a TEE-based, non-custodial model that requires no seed phrases. - **OKX Pay**: A payment product designed to merge crypto payments with DeFi, aiming for mass adoption. X Layer, OKX’s blockchain, was positioned as the scalable backbone, targeting 5,000 TPS, 400ms block times, and near-zero fees. Zakk stressed the importance of sustainable ecosystem growth—focusing on project incubation and diverse applications beyond trading, such as RWA and AI. With stablecoins approaching trillion-dollar scale, OKX aims to make Web3 accessible, secure, and practical for billions.

Ledger eyes $4bn US IPO as critics question past breaches and new fee strategy

Ledger, a Paris-based hardware wallet manufacturer, is reportedly planning a US IPO that could value the company at over $4 billion. The potential New York listing, which could occur as early as this year, highlights the growing investor appetite for crypto infrastructure firms. Founded in 2014, Ledger has benefited from increased demand for self-custody solutions. However, the announcement has reignited scrutiny over the company's past security breaches, including a 2020 data leak of customer information. Critics have also questioned Ledger's recent decision to introduce new fees for security features, with some viewing it as a value extraction move ahead of the public listing. If the IPO proceeds, investors are expected to closely examine both the firm's growth potential and its historical security track record.
