According to official news, B.AI has made several advancements this week in product iteration and ecological layout: the BAIclaw landing page has undergone a complete visual and interactive renewal, and the website's multilingual support has expanded to 10 languages, further solidifying its global usability; in terms of infrastructure, strategic partnerships with Biconomy, MoonPay, and Pundi X have significantly optimized the Web3 payment link, greatly lowering the entry barrier for users. Meanwhile, B.AI's multi-chain LLM service continues to evolve, covering intelligent search, boundaryless mode, and memory functions, with significantly enhanced interactive performance. In the future, with the upcoming subscription system, points incentive mechanism, and core Skills like "Sun Yuchen Brain," B.AI is accelerating the construction of a fully functional intelligent ecological matrix, relying on the deep integration of AI Agent and Web3.

The FLOA ecological core AI suite FloaClaw has officially launched in full, simultaneously introducing a multi-scenario AI skill matrix. The functionality is only available to Agents of level 3 and above, marking an important breakthrough for FLOA in the integration of AI and Web3.As the core AI tool of the FLOA ecosystem, the use of FloaClaw must follow clear rules: users need to recharge BNB to obtain computing power tokens, and skill consumption increases with task complexity. In the future, FloaClaw will continue to iterate and expand, opening up more new AI skills and tool modules, while promoting a creator dividend system that allows Agent creators to share in the computing power token earnings from user skill consumption, and supports one-click exchange and withdrawal of BNB, building a sustainable creator economy closed loop.FLOA is a smart Web3 Agent ecological platform deeply rooted in the BNB Chain ecosystem, integrating core capabilities such as data analysis and on-chain automation. With an open incentive mechanism, it serves as both a user empowerment tool and an efficient growth engine for the Web3 ecosystem, continuously laying out the integration of AI and Web3.

The prediction market platform Polymarket will undergo a V2 exchange upgrade on April 28 at 19:00, and will be down for approximately 1 hour. The V1 order book will be cleared, and all open limit orders will be canceled. Users trading via API need to update to the latest version of the SDK before the upgrade, as the V1 client will no longer be usable after the upgrade.

Coinbase stated that it is optimizing the rule creation process in its anti-fraud system by integrating machine learning models with a rules engine, achieving more efficient risk management. It also proposed a dual-track strategy of "models responsible for long-term defense, rules responsible for rapid response," and built a unified framework to create a feedback loop between the two: rules are used to capture new types of fraud and train the model in reverse, thereby continuously enhancing overall defense capabilities.In terms of specific optimizations, Coinbase has transformed the previously manual rule creation process into a data-driven and automated recommendation system by restructuring data, automating schema evolution, and introducing notebook-based analytical tools, significantly improving efficiency. Among these improvements, the performance of rule backtesting has increased by more than 10 times, and the overall response time has been reduced from several days to a few hours. Additionally, the new system uses machine learning to recommend parameters, helping to reduce false positive rates while combating fraud and minimizing the impact on normal users. Coinbase indicated that the next step will be to advance event-driven automatic rule generation and explore the "one-click conversion" of efficient rules into model features, further moving towards an automated risk management system.

Base announced that its first independent network upgrade, Base Azul, has gone live on the testnet, with the target mainnet activation date set for May 13, 2026. This upgrade is the first network-level upgrade for Base independent of the OP Stack.The official statement indicates that Azul will enhance security, performance, and developer experience in three areas: Base will enable a multi-proof mechanism through Azul, base-reth-node will become its sole execution client, and it will adopt the latest execution layer specification (Osaka) to keep Base aligned with Ethereum. Users do not need to take any action for this upgrade.

The Coinbase Quantum Computing and Blockchain Independent Advisory Committee has released its first position paper stating that sufficiently powerful quantum computers may be able to crack the encryption mechanisms used by mainstream blockchains to protect digital assets in the future. However, such devices do not currently exist, and encrypted assets remain secure for now. The industry should begin preparing for quantum resistance upgrades starting now.The document points out that there are currently no substantial risks associated with Bitcoin mining, hash functions, and on-chain historical records; the main vulnerability lies in the digital signatures at the wallet layer. Ethereum has proposed a clearer migration roadmap, and Solana, Algorand, and Aptos have also begun to provide or plan quantum resistance solutions.

Sonic elaborates on its technological path towards the "post-quantum era," pointing out that most current PoS public chains rely on elliptic curve signatures (such as ECDSA, Ed25519), which are at risk of being cracked once quantum computing (like Shor's algorithm) matures.Sonic states that the industry is exploring post-quantum cryptographic solutions (such as hash-based XMSS, SPHINCS+, and lattice-based Dilithium, Falcon), but mainstream consensus mechanisms generally rely on BLS aggregate signatures and threshold signatures, making the transition to post-quantum systems face challenges in performance, bandwidth, and architectural reconstruction. In contrast, Sonic's SonicCS consensus protocol does not rely on aggregate signatures or global randomness, but instead uses single-node signatures and hash functions to construct a DAG structure. Therefore, when switching to post-quantum cryptography, only the signature algorithm needs to be replaced to complete the upgrade, without the need to adjust the consensus logic or network structure. Sonic emphasizes that this design will significantly reduce the complexity of future migrations to post-quantum security, enabling the network to have stronger adaptability when quantum computing threats arise.

According to The Block, Josh Stark, a key figure at the Ethereum Foundation (EF), announced his resignation after five years and will officially step down at the end of the month. Stark joined the Ethereum Foundation in 2019, initially working in the special projects team, and later rose to leadership, collaborating with EF Chair Aya Miyaguchi, Ethereum founder Vitalik Buterin, and co-executive directors Hsiao-Wei Wang and Bastian Aue.He is one of the most prominent members of the foundation's external image and has led several significant advancements in Ethereum, including the "The Merge" upgrade that transitioned from proof of work to proof of stake, as well as subsequent upgrades like Dencun, Fusaka, and Pectra. During last year's leadership adjustments at the foundation, he was appointed as the "co-manager" of the EF board and recently took on the role of co-chair of the "trillion-dollar security" initiative.Last month, Stark co-authored a strategic blog post on Ethereum with Josh Rudolf and Julian Ma, outlining Ethereum's latest scaling direction and its relationship with the Layer 2 ecosystem. Stark stated, "I haven't planned for the future yet; I just want to take a good rest and spend time with family and friends." This resignation occurs against the backdrop of ongoing changes at the Ethereum Foundation.Last year, the foundation underwent significant leadership adjustments, refocusing its strategic priorities on scaling the Ethereum mainnet and core cypherpunk values; Tomasz K. Stańczak also resigned from his co-executive director position at the end of February this year, having served for less than a year. On the same day, Trent Van Epps also announced his departure from EF to fully dedicate himself to Protocol Guild, the independent funding organization for Ethereum core developers that he founded.

Blockstream CEO Adam Back stated that Bitcoin should adopt an optional quantum-resistant upgrade scheme, rather than the mandatory freezing of tokens at risk from quantum threats proposed in BIP-361.The BIP-361 proposal suggests phasing out addresses vulnerable to quantum attacks over five years and ultimately freezing un-migrated tokens, including assets held by Satoshi Nakamoto. Google's latest research indicates that a superconducting qubit system may need fewer than 500,000 physical qubits to crack Bitcoin encryption in just a few minutes. Currently, about 6.9 million BTC are at risk from such threats. In response to the quantum threat, BitMEX Research proposed establishing a canary fund that would implement a full freeze only when expenditures occur from the relevant addresses.

According to market news, Blockstream CEO Adam Back stated at the Paris Blockchain Week that he supports the optional advancement of Bitcoin's quantum resistance upgrade and opposes the proposal to forcibly freeze quantum-vulnerable addresses. He emphasized that "preparation is much safer than hasty responses in a crisis" and pointed out that the Bitcoin community has the coordination ability to respond quickly to urgent vulnerabilities.Previously, the BIP-361 proposal ("Post-Quantum Migration and Legacy Signature Sunset") put forward by developers Jameson Lopp and five others advocated for the gradual elimination of quantum-vulnerable addresses over five years, ultimately freezing coins that have not completed migration— including approximately 1.7 million Bitcoins held by Satoshi Nakamoto.

HIVE Digital Technologies (NASDAQ: HIVE) announced plans to issue $75 million of zero-coupon convertible senior notes due 2031 through a private placement to qualified institutional buyers, with an additional $15 million overallotment option for initial purchasers. The proceeds will be used for GPU procurement, data center construction, and general corporate purposes.Meanwhile, HIVE has received conditional listing approval from the Toronto Stock Exchange (TSX) and is expected to officially graduate from the TSX Venture Exchange to the TSX main board on April 30, 2026.

According to CoinDesk, Blockstream CEO Adam Back stated at Paris Blockchain Week that Bitcoin developers should advance optional quantum-resistant upgrades as early as possible, even though practical quantum computers are still far from being realized.He pointed out that Taproot's flexible design can support the introduction of new quantum-resistant signature schemes without affecting existing users. Previously, Jameson Lopp and others proposed BIP - 361, which aims to gradually phase out addresses vulnerable to quantum attacks within 5 years and freeze Bitcoin that has not completed migration. Adam Back believes that the Bitcoin community can quickly coordinate responses in emergencies without the need for pre-established freezing arrangements.

Bitget today announced the completion of an upgrade to its underlying trading infrastructure. By restructuring the core modules of the matching engine cluster and account system, the order processing delay has been reduced by up to 40%. This upgrade is aimed at all platform users, including Bitget PRO users and market maker users.After the upgrade, the platform can provide faster order reception and status feedback speeds, significantly shortening the response chain from order submission to matching execution. During periods of significant market fluctuations, it further ensures the execution efficiency and transaction stability of large orders and complex trading strategies, continuously optimizing the overall trading experience.Bitget CEO Gracy Chen stated, "The market is ever-changing, and trading tools must evolve in sync. Continuously optimizing matching performance aims to create a reliable execution foundation for traders. Under the UEX strategic framework, this upgrade will further enhance trading efficiency and liquidity capacity within a unified account system, providing more stable and efficient infrastructure support for the integration of crypto assets and traditional assets."

The full-chain token issuance platform Printr announced the launch of the V2 upgrade, which introduces five new fee distribution models, including buyback and burn, liquidity compounding, POB staking, creator sharing, and zero-fee mode.Among them, the POB (Proof of Belief) mechanism allows users to share 100% of custom transaction fee earnings by staking tokens. V2 also launches configurable issuance parameters, automatic liquidity migration, and anti-copy protection features, and now supports 8 chains including Solana, Base, BNB Chain, and Ethereum.

Bitfinex released a report indicating that tokenized commodities are moving from early experimentation to practical application, becoming an important manifestation of the reconstruction of real-world assets (RWA) on the blockchain. The core of this shift is not to create new demand, but to reshape existing market infrastructure.Data shows that the total market value of tokenized commodities has reached approximately $7 billion, growing nearly 600% since the beginning of 2025. Current major participants include crypto-native investors and high-net-worth individuals. Amid increasing geopolitical volatility, tokenization is enhancing asset liquidity and risk management flexibility. Gold remains the primary entry point, with Tether Gold accounting for nearly 40% market share.The report points out that on-chain gold possesses characteristics such as real-time transfer and global auditability, making it more suitable as collateral compared to physical assets, and it can overcome traditional trading hours and settlement limitations. In addition to gold, tokenized commodities have expanded into areas such as oil, natural gas, and agricultural products, with soybeans and soybean oil each around $400 million, and green financing-related exposure around $850 million, indicating that this model has cross-category expansion potential.At the same time, the traceability of blockchain has also enhanced supply chain transparency, meeting regulatory and ESG requirements. Bitfinex believes that in the future, the focus of tokenization will shift from precious metals to industrial products such as copper and oil, achieving a transition from "product innovation" to "market infrastructure upgrade" by improving collateral efficiency, asset circulation speed, and transparency.

Telegram founder Pavel Durov stated that The Open Network (TON) has completed a major upgrade, increasing block generation speed by 6 times, overall performance improved by about 10 times, and transaction confirmation time has been reduced to sub-second levels, achieving a "near-instant" transaction experience.TON officials stated that this upgrade is based on Catchain 2, and the previous confirmation time of about 10 seconds limited instant payments and application response experiences, while this upgrade will make it possible to "complete payments like sending messages." In addition, TON also stated that higher block generation frequency will enhance validator earnings and strengthen staking incentives. Pavel Durov called this upgrade the first step of the "Make TON Great Again" seven-step plan, with the next phase aiming to further reduce transaction fees by about 6 times.

Telegram founder Pavel Durov stated on social media, "The TON blockchain has just completed an upgrade, and now the speed has increased by 10 times. The block generation speed has increased by 6 times, and transactions now achieve instant, sub-second confirmations. This is the first step in the 'Make TON Great Again (MTONGA)' seven-step plan. The next step is to reduce the already low transaction fees by another 6 times."
