Tencent Cloud opens Yuanbao search, multiple vendors launch search API

According to Beating reports, Tencent announced the opening of Yuanbao Search to developers through Tencent Cloud, supporting API, MCP, and Skill access. Tencent disclosed that this search service has an index of hundreds of billions, with an average daily call volume of hundreds of millions, and has supported over 50 internal businesses including WorkBuddy, ima, and Tencent Video. The underlying technology of Yuanbao Search comes from Sogou Search, integrates Tencent's content ecosystem, and connects to 157 authoritative sources across 13 industries including finance, healthcare, and law.Records from the Tencent Cloud Internet Search API show that this service went live on July 1, 2025. Alibaba Cloud launched its independent Internet Search API on March 20 of the same year; Volcano Engine upgraded its existing service to Doubao Search in June this year and officially released it to the public in July; DeepSeek opened its self-developed search engine's Search and Fetch API on October 17. The prices for Yuanbao Search's Express, Standard, and Premium versions are 14 yuan, 20 yuan, and 26 yuan per thousand calls, respectively, with an additional monthly free quota of 2,000 calls; the Express version only supports public web sources. The price for DeepSeek Search API is 5 yuan per thousand successful requests, Alibaba Cloud OpenSearch Lite is 12 yuan, and the Pro version was reduced to 18 yuan on October 15.

first_img Cryptocurrency lending deposits exceed 10 billion USD, regulatory review of lending risks

According to the Financial Times, the deposit scale of crypto lending vaults has surpassed $10 billion, a significant increase from $4 billion at the beginning of last year, reflecting the growing demand from investors for digital asset yield strategies. These vaults operate through smart contracts on decentralized finance platforms, with each vault having a "curator" who effectively acts as an investment manager responsible for selecting lending strategies, setting risk limits, and charging fees. Their yields typically range from 3% to 10%, with riskier strategies yielding up to 20% or even higher.The allure of returns comes with significant risks. Loans may be collateralized by illiquid tokens, crypto-asset-backed stablecoins, or tokenized private credit, and if the collateral depreciates or becomes difficult to sell, depositors will face losses. Automatic liquidation may exacerbate market downturns, while hacking attacks, code errors, and pricing mechanism flaws can introduce additional vulnerabilities. Although publicly accessible smart contracts provide transparency, investors may focus only on surface yields while overlooking their underlying risk exposures. Major depositors currently include fintech companies, digital asset treasury firms, and hedge funds.Bitcoin lending institution Two Prime is one of the companies that recently entered this market. The company launched a Bitcoin lending vault on the Pareto platform in September, targeting an annualized yield of 1.5% to 2% through institutional lending. This vault accepts wrapped Bitcoin, with a minimum deposit of 5 WBTC, and has invested approximately $10 million of its own funds to absorb initial losses. On the regulatory front, the U.S. Securities and Exchange Commission has raised questions regarding the securities held by the vaults, while European regulators have proposed regulating intermediaries that provide access to DeFi.

Bybit CEO: By the end of last year, the stolen losses have been compensated, and the golden period of global expansion has passed

Bybit CEO Ben Zhou recently stated in an interview with Wu Shuo that Bybit has covered the losses caused by previous attacks from North Korean hackers through operational income such as transaction fees by the end of last year. He believes that there will still be trading platforms that encounter hacker attacks in the future, and the security system should be designed with the premise of "assuming it will definitely be hacked."Regarding competition, Ben Zhou believes that the golden period for the expansion of global trading platforms has passed, and the industry will further consolidate. Regional trading platforms with licenses and local operational capabilities still have opportunities. He revealed that Bybit's profits have declined year-on-year this year, and traditional asset trading businesses such as stocks are currently not enough to offset the impact brought by the cryptocurrency business.In terms of the U.S. market, he stated that Bybit is still waiting for the right opportunity to enter and is more inclined to cooperate with local institutions that have a retail user base. The core strategy for the next year will focus on regional development and deep localization. He also discussed the differences between the Bitget security incident and the Bybit theft incident, as well as the data security challenges brought by the large-scale application of AI within the platform.

first_img The Zcash development team plans to allocate independent keys for each ZEC exchange to prevent quantum cracking

The Zakura team, which operates the Zcash network, released a technical article stating that they plan to allocate a unique viewing key for each ZEC exchange completed through NEAR Intents, in order to block future quantum computers from exploiting public refund addresses to piece together user payment histories. NEAR Intents supports cross-chain token exchanges, and when users exchange the privacy coin ZEC for USDC, the service will publish a Zcash address for the user on the NEAR public blockchain, which will be used to return any unused ZEC.The Zcash address contains a public key generated by the wallet's viewing key, which cannot be reverse-engineered by ordinary computers, but large quantum computers running Shor's algorithm could theoretically deduce the key from the address. Zcash wallets can generate multiple seemingly unrelated addresses, but they typically share the same viewing key. Once an attacker cracks it, they can associate all payments received by the account and read the amounts and notes. Zakura's solution allocates a unique viewing key for each exchange, while the spending key remains in the user's main account. Even if the future refund address is compromised, the attacker would only be able to see payments related to that specific exchange.This design also addresses a practical issue: wallets conducting hundreds of exchanges would generate hundreds of keys, requiring each key to scan the entire Zcash chain during backup recovery. Zakura's solution is a privately queryable database that uses private information retrieval technology, so when the wallet inquires about the refund destination, the database will not know the address being queried. Zakura claims that wallets built on its open-source library (including Vizor) will be able to add this feature in the coming weeks, and hardware wallets will follow after firmware support, ahead of the January quantum-resistant payment target set by Zcash developers this month.

first_img The XRP Ledger lending code fix is close to taking effect, but the lending amendment still lacks 10 votes

The XRP Ledger vulnerability fix package named fixCleanup3_4_0 is expected to officially take effect around 09:34 UTC on October 23. This fix package has received votes from 29 validators, surpassing the threshold of over 80% approval among the network's default 35 validators, and must be maintained continuously for two weeks. The countdown has been ongoing for nine days. Since there is no margin in the vote count, if any validator withdraws support, the countdown will restart.This fix package partially addresses the unsecured lending system that Ripple has been promoting to banks and payment companies since June, but this system has not yet been activated. Currently, the lending amendment has only 19 votes, and the vault amendment for holding funds has 21 votes, neither of which has started the countdown. Therefore, even if both reach 29 votes today, the lending function will not be available until early November at the earliest.As designed, lenders will deposit XRP or other tokens into the vault, and loan brokers will then lend out the funds for a fixed term. The ledger is responsible for recording the loans and tracking repayments, while brokers assess the borrower's qualifications off-chain. Since borrowers do not need to provide collateral, the broker's judgment becomes the only guarantee for lenders against default losses. Ripple has promoted this scheme to payment companies that need liquidity during cross-border settlement. Additionally, the fix package also closes a vulnerability that allowed accounts authorized to destroy tokens to create new tokens under specific conditions and adjusts the rounding of vault amounts as well as the rules for determining loan overdue and default.
