Muneeb Ali, co-founder of the Bitcoin Layer2 network Stacks, stated in Cointelegraph's Chain Reaction podcast that concerns surrounding quantum computing are suppressing institutional funds from entering Bitcoin, and the network needs a credible security upgrade roadmap to restore investor confidence. He mentioned, "Quantum concerns have set a ceiling on Bitcoin's growth," believing that this uncertainty may lead risk-averse institutional investors to delay large purchases until developers provide a clear path to quantum resistance. Stacks is a Bitcoin Layer2 network aimed at introducing smart contracts and decentralized applications to Bitcoin, and Ali is a co-founder of the project.Ali warned that if developers fail to make substantial progress in quantum resistance by 2028, Bitcoin could enter a riskier phase. He pointed out that upgrades typically take years to implement, and users will need additional time to migrate their assets to new addresses. Citing guidance from the National Institute of Standards and Technology (NIST), he views 2030 as a target node for transitioning to quantum resistance and believes advancements in artificial intelligence could accelerate the development of quantum computers, potentially moving this timeline up to 2029.Ali acknowledged that some Bitcoin supporters believe the quantum threat is distant and that concerns are exaggerated, but he thinks that the very disagreement over the urgency of the threat, in the absence of a credible upgrade roadmap, will undermine investor confidence. He also stated that sufficiently powerful quantum computers are more likely to emerge from large research laboratories rather than unknown attackers, and companies like Google and Microsoft lack the motivation to steal Bitcoin, but the quantum security threat will impact the entire crypto industry, "If Bitcoin is hit, all downstream projects will be affected." Currently, developers are exploring protective solutions, with StarkWare stating in September that researchers reduced the computational cost of preparing an experimental quantum-resistant Bitcoin transaction by 79% after a week of optimization challenges. This solution does not require modifications to Bitcoin's consensus rules, but the cost reduction has only been validated in benchmark tests.

Due to the ChainSecurity report revealing compatibility and security issues with EIP-8037 and certain smart contracts, core developers decided last week to postpone the Hoodi testnet upgrade to Glamsterdam. The issues identified so far include: the remaining Gas during transaction execution may increase, leading to underflow in some Gas counting logic and triggering rollbacks, or causing code paths that should not be executed to be triggered, making the transaction appear successful. Additionally, some contracts may underestimate usage due to the inability to correctly calculate Gas consumption during calls.ChainSecurity previously stated that 13 real cases have been identified and they are responsibly disclosing this information to the affected projects. Toni Wahrstätter mentioned that this week they will further investigate the relevant contracts and assess subsequent solutions, which may require collaboration among application developers, core developers, auditors, and node operators. In the worst-case scenario, adjustments to the protocol specifications may be necessary. He reminded application developers and auditors to check the compatibility of contracts with EIP-8037 and EIP-8038 and to report issues in a timely manner.

According to official news from Bitget, the platform announced a collaboration with the structured product liquidity service provider VETA Finance to upgrade its stock dual-currency investment products.

JUST announced an upgrade to the buyback and destruction mechanism for JST. After completing the fifth round of buyback and destruction, the mechanism officially enters a new phase: governance will be unified by the JUST DAO, and a reserve fund of no less than 50 million USD will be established for risk mitigation, emergency redemptions, and liquidity support, to enhance the mechanism's risk resistance and execution stability.On the buyback side, it will shift to being executed based on the quarterly sustainable income of the JUST ecosystem, forming a normalized arrangement of long-term buybacks and regular destructions, making the scale of buybacks more closely tied to the actual income of the ecosystem.In addition, the remaining surplus funds above the reserve threshold, approximately 20.34 million USD, will be released in four phases starting from Q4 2026 to supplement the buyback, ensuring long-term deflation and stability of the mechanism. The complete announcement and implementation details can be found through official channels.

The privacy Layer 2 network Aztec, based on zero-knowledge proofs, announced that its V6 upgrade proposal has been approved, but the governance panel currently still shows that voting is open, with the execution date listed on the panel as October 26.According to disclosures, the upgrade will enhance the messaging speed between Ethereum and Aztec, and will provide 30 days of operational funding for the V5 version during the migration period.

The blockchain infrastructure layer Espresso announced the completion of its mainnet upgrade. Benchmark tests show that its data throughput reaches 181 MB/s, which translates to approximately 1 million stablecoin transfers per second, based on an average of 180 bytes per transaction.The average final confirmation time for transactions is 337 milliseconds, and under peak load of 1 million transactions per second, it is 778 milliseconds.

According to security researcher Spreek (@spreekaway), the management keys of swETH and rswETH under Swell DAO are suspected to have been leaked, and attackers are raising the uncollateralized NAV (Net Asset Value) by up to 1% per hour. Currently, four malicious upgrade contracts have been detected and have not yet been queued for execution through multi-signature; if executed, they could steal approximately 2,500 ETH.Additionally, according to analysis by ADL (@ADLXBT), the management keys control the proxy administrator permissions. Once controlled by attackers, they can direct the swETH/rswETH proxy to malicious implementation contracts, triggering minting or withdrawal functions, thereby inflating the NAV without asset backing. Spreek stated that whether this incident is related to the Railway platform remains speculative; it is currently just a coincidence in timing, with no conclusive evidence available.
