According to ChainCatcher, Space and Time, a blockchain data project backed by Microsoft, announced the launch of the Space and Time Enterprise platform, which allows businesses to use private data with AI tools without handing over the underlying records. The platform can prove that computations performed on private data are correct, enabling AI applications, auditors, and other relevant parties to verify results without accessing the databases themselves. Its first partners include on-chain asset manager Maple Finance, Indonesian automotive manufacturer and distributor Indomobil, Oracle software consulting firm Trenez, and The Data Foundation, a Washington, D.C.-based nonprofit focused on government data.

ChainCatcher reports that Binance Chief Security Officer Jimmy Su said during a Binance X Space fireside chat that Binance is hiring external security experts to conduct a comprehensive, independent review of the security incident that occurred on October 29, verify the findings of its internal investigation, and offer recommendations for improvement.
Meanwhile, Binance is working with partners, including leading AI companies and security firms, to establish a security research fund focused on security threats related to blockchain and AI. It will also manage its internal AI tools and development environments according to critical infrastructure standards.
Regarding the security incident, Jimmy Su explained that the transaction authorization exploited by the attackers existed on-chain and did not pass through Binance’s withdrawal system. As a result, suspending withdrawals could not prevent the associated funds from being transferred; the authorization had to be revoked through a new on-chain transaction.

ChainCatcher reports that Brazilian crypto exchange Mercado Bitcoin announced it will begin restoring platform access in phases this week. Customers can log in to their accounts through the website again, with access gradually reopening from 16:00 local time and expected to reach all customers by 18:00.
The exchange had previously suspended deposits and withdrawals following a hack. Media outlets and on-chain analytics firms estimate the losses at between $38 million and $46 million. The exchange said customer balance records remained intact during the incident, and that records of each customer’s assets, investments, and Brazilian real balances on the platform were unaffected. Mercado Bitcoin will use its own funds to make up for the balances transferred out of customers’ accounts. Balance updates will be made as the platform reopens and trading resumes.

ChainCatcher reports that Acala, a DeFi network in the Polkadot ecosystem, has announced that after seven years of development, Acala and its sister network on Kusama, Karura, are entering their final phase. Subject to the approval of Acala Referendum No. 195 and Karura Referendum No. 137, both networks will cease operating on February 10, 2027. After that date, Acala and Karura will no longer produce new blocks.
Users must withdraw DOT, KSM, and assets bridged from other chains, such as USDT and USDC, from Acala and Karura by February 10, 2027. Unstaking LDOT takes 28 days, so unbonding must be initiated by January 12, 2027. If LDOT is locked with a validator, it will take an additional 28 days to unlock, so the unlock process must be completed by December 16, 2026. Unstaking LKSM takes 7 days, so unbonding must be initiated by February 2, 2027.
