Vitalik:Diamond iO 探索程序“隐身”新范式,或推动隐私计算迈向新阶段

火星财经消息,以太坊联合创始人 Vitalik Buterin 发布最新文章,介绍新型密码学混淆技术 Diamond iO。该技术旨在解决传统不可区分混淆方案效率极低的问题,使程序能够在隐藏内部逻辑和关键数据的情况下运行。传统 iO 技术虽然具备强大的隐私保护能力,但运行成本高到几乎无法实践,而 Diamond iO 通过采用更激进的新型密码学假设,将计算效率从“宇宙级耗时”提升至“行星级耗时”,距离实际应用进一步靠近。Diamond iO 基于属性加密(ABE)和全同态加密(FHE)等技术构建,通过对程序进行加密,使用户可以执行加密后的程序并获得正确输出,却无法查看其内部代码或隐藏密钥。该方案引入新的输入编码机制和条件解密方式,在保证程序逻辑隐藏的同时降低计算复杂度。其核心应用场景包括保护包含私钥的程序、实现安全的软件授权、构建无需信任的密码学服务,以及支持更强隐私保护的区块链和人工智能系统。不过,Diamond iO 目前仍处于早期研究阶段,其安全性依赖于包括 All-Product LWE 和 Evasive LWE 在内的新型密码学假设,尚需更多研究验证。同时,该技术仍面临计算开销大、电路深度限制等效率挑战。研究人员认为,通过优化底层哈希函数、改进同态加密方案以及降低安全参数要求,未来 Diamond iO 有望成为推动实用化程序混淆技术发展的重要方向。

Vitalik Buterin released a new proposal suggesting that the consensus layer state be drastically reduced to only 6 bytes.

According to Foresight News , Vitalik Buterin has released a new proposal, "The Extremely Lean Chain." The core of this proposal is to significantly simplify the state stored by each validator in the current Beacon chain (public key, withdrawal certificate, activation/exit epoch, etc.), retaining only 6 bytes (1 byte for effective balance + 5 bytes for deposit tree index). Validators will need to track their deposit Merkle proofs themselves and asynchronously update their effective balance and participation records using daily generated STARK proofs, instead of having these updates processed in real-time on-chain every epoch. The proposal is planned to proceed in multiple phases: removing public key storage and replacing it with a deposit tree index, with daily STARK proofs used to update the balance; subsequently, a daily public key refresh mechanism will be introduced to achieve strong anonymity of validator identities, while naturally supporting Single Secret Leader Election (SSLE). This design is considered feasible in the context of Lean upgrades such as single-slot finality (SSF) and recursive STARK, aiming to significantly reduce consensus layer state overhead and computational burden, support the number of validators to the millions, and provide strong privacy protection in advanced versions.

Vitalik specifically praised the Thousand Questions model for its outstanding anonymous identification capabilities.

ChainCatcher reports that Vitalik Buterin has announced a winner in his AI anonymization challenge. In the challenge, he wrote a revised version of EIP-7503 (Zero-Knowledge Wormhole) in Chinese in 2024, manually correcting it after using Qwen 2.5 for local translation, attempting to conceal his authorship. The article states that although the essay style was effectively obscured, the AI successfully identified the author by detecting unique thought processes in mathematical and algorithmic explanations (such as concrete numerical examples and logical chains), completely bypassing its obfuscation strategy, which was only applied to essays.

Binance Research: Over 700 Binance equity products have been traded, with 71% of holdings allocated to the technology sector.

According to ChainCatcher, Binance Research's monthly market insights show that over 700 of the approximately 7,000 stocks and ETFs tradable on Binance have already seen trading activity, indicating initial user participation in equity products. The report states that about 71% of Binance equity holdings are allocated to the technology sector, with approximately 48% of funds flowing into semiconductors, a category with trading volume about 23 times that of other categories. In terms of thematic fund flows, Binance equity holders' allocations are relatively diversified, with 25% flowing into AI infrastructure and computing power, 22% into quantum computing, and relatively higher allocations to cutting-edge themes such as space and satellites, robotics and humanoid robots. Meanwhile, broader ETF fund flows are primarily concentrated in semiconductors and AI storage. Furthermore, the report shows that at the portfolio level, 41% of Binance equity holders' holdings are allocated to crypto assets, 37% to stablecoins, and 22% to stocks.

Institutions: Comprehensive upward revision of Q1 DRAM and NAND Flash price growth forecasts for all products.

According to BlockBeats' latest memory industry survey, released on July 6th, demand from AI and data centers will continue to exacerbate the global memory supply-demand imbalance in the first quarter of 2026, further increasing manufacturers' bargaining power. Based on this, TrendForce has comprehensively revised upwards its Q1 price growth forecasts for all DRAM and NAND Flash products. It predicts that the overall Conventional DRAM contract price will increase by 90-95% from the 55-60% increase announced in early January, while the NAND Flash contract price will be revised upwards from 33-38% to 55-60%, with further upward revisions not ruled out.

Vitalik comments on the EU's renewed push for "chat control" legislation.

According to Foresight News , Ethereum co-founder Vitalik Buterin shared and commented on the X platform that the European Union is once again trying to push for legislation related to "chat control". The post it forwarded pointed out that this was the sixth time the EU had attempted to enforce the law, which would allow the scanning of all of a user's private messages, photos, and emails without a warrant.

Vitalik, founder of Liquid, identified the anonymous documents by analyzing the habits of the mathematical and algorithmic explanations.

According to Foresight News , Vitalik Buterin tweeted that Liquid founder Franklyn Wang successfully identified his anonymized experimental document. In 2024, Vitalik wrote content in Chinese, then translated it into English using a local Qwen2.5 model, and finally manually corrected the translation issues to test whether it could effectively hide his personal writing style. Franklyn Wang successfully identified the anonymous document as originating from Vitalik by analyzing the unique habits in the mathematical and algorithmic explanations (such as specific numerical examples and attack scenario descriptions). According to a previous Foresight News report, Vitalik Buterin tweeted that his anonymity experiment had been going on for "13 days" and "no one has found it yet." He added that he encouraged people to "broaden their search scope slightly," noting that he had seen many search behaviors and AI scripts miss document categories that should have been included.
