upgrades

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.

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.

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.

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."

Sky Governance announced on April 7 two structural upgrade proposals aimed at strengthening the capital protection framework of the protocol. The two proposals are: implementing a stronger solvency buffer mechanism and adopting a more sustainable staking reward model, with the goal of consolidating the long-term stability of the protocol and placing credibility above the pursuit of short-term gains.Sky Protocol pointed out that its yield-bearing stablecoin sUSDS is the largest in its category, attributing this success to the protocol's unique risk positioning compared to its competitors.

According to on-chain analyst Yu Jin's monitoring, about 1 hour ago, Resolv Labs destroyed 36.73 million USR held by the hacker through a contract upgrade.The hacker minted 80 million USR through a minting vulnerability without collateral, of which approximately 34 million USR were sold off by the hacker for 11,409 ETH (24.48 million USD) stored at the address 0x8ED...81C. Additionally, about 46 million USR were destroyed from the hacker's address by the Resolv project team through a contract upgrade. The actual loss from this vulnerability exploitation incident for Resolv is 34 million USD.

According to the official blog, Circle's institutional-grade blockchain Arc has released a phased upgrade roadmap for post-quantum cryptography (PQ), planning to introduce post-quantum signature schemes at the launch of the mainnet, gradually covering full-stack layers such as private state protection, infrastructure hardening, and validator authentication.The Arc mainnet will support post-quantum signatures from the outset, using an opt-in mechanism that does not require mandatory migration or a full network reset, allowing users to independently create wallets with long-term security. The recent goal is to extend quantum resistance to the private virtual machine (VM) layer, protecting private balances, private transactions, and private payees, with public keys additionally encapsulated in a symmetric encryption layer under privacy mode.The mid-term plan is to advance the upgrade of the infrastructure layer, aligning with industry standards such as TLS 1.3, covering access control, cloud environments, and hardware security modules (HSM). The long-term goal is to complete the hardening of validator signatures. Given that Arc's block finalization time is less than 1 second, the current assessment considers the risk of quantum attacks in this phase to be relatively limited, and it will be steadily advanced after the post-quantum consensus toolchain matures.Circle also warns that attackers may adopt a "collect now, decrypt later" strategy, and institutions should plan their cryptographic migration paths as early as possible.

JAN3 CEO Samson Mow posted on the X platform, stating that the current response to the threat of quantum computing (QC) to Bitcoin should not be rushed. Blindly and hastily switching from the existing signature mechanism to post-quantum (PQ) solutions may expose Bitcoin to the risk of classical computing attacks in the short term. The size of PQ signatures could increase by 10 to 125 times, significantly reducing network throughput and potentially triggering a repeat of the scaling disputes similar to the early "block wars."In addition, Samson Mow warned that some PQ solutions may have potential backdoor risks. The threat of quantum computing is still in the medium to long-term stage (which may take 10 to 20 years). The more reasonable path currently is to continue research rather than rush deployment. He also specifically mentioned Coinbase, stating that its wallet has quantum attack vulnerabilities due to address reuse, and suggested prioritizing the repair of related infrastructure issues.

The Ethereum Foundation released a new roadmap on Tuesday, outlining how the development team is preparing for the threats posed by quantum computing.The Foundation's quantum team expects a series of preliminary upgrades to the network to be completed by 2029, primarily involving four key hard forks. The Foundation stated that quantum computing will eventually break the public key cryptography that protects ownership, authentication, and consensus in all digital systems, but this threat is not expected to arrive immediately. Researchers from the Foundation's quantum team anticipate that quantum computing with cryptographic capabilities will not emerge for another 8 to 12 years.Among the four hard forks, the "I" fork will provide network validators with quantum-safe public keys, and the "J" fork will reduce the Gas fees for validating quantum-safe signatures; both upgrades have been included in the considerations for the Hegota fork expected to take place later this year. The "L" fork will express the network state as zero-knowledge proofs, while the "M" fork will protect Layer 2 networks from quantum threats.Researchers indicated that Layer 1 protocol upgrades could be completed by 2029, while a complete migration of the execution layer will require several additional years thereafter. The Ethereum Foundation established a dedicated quantum team in January of this year, and a developer testnet began testing some quantum features in March.

According to Crowdfund Insider, Binance has upgraded its lending services, launching an improved Flexible Loan product that allows users to obtain liquidity without selling their assets.This product is an over-collateralized, open-term isolated lending solution, with a minimum loan amount equivalent to 1 USD. It supports borrowing and repayment at any time, and no fees are charged for either. The collateralized assets will automatically connect to the Simple Earn flexible product, continuously generating earnings every minute, achieving "earn interest while collateralizing." The loan interest rate is also refreshed every minute to reflect real-time market conditions. Borrowed funds can be used for spot trading, leveraged positions, contract trading, or further staking, with supported assets including mainstream tokens like BTC, ETH, and USDT.The platform has a built-in risk monitoring mechanism, but users still need to actively manage their positions and maintain sufficient collateral buffers to prevent forced liquidation. Binance stated that this upgrade is particularly suitable for long-term holders like Bitcoin miners, allowing them to cover operational costs or seize market opportunities without reducing their asset holdings.
