DA in the field of encryption usually refers to "Data Availability." It is a key concept in blockchain technology, involving ensuring that on-chain data can be accessed and verified when necessary. Data availability issues are particularly important in blockchain scalability, as they affect the security and decentralization of the blockchain. Solutions to data availability problems include techniques such as data sharding and the use of data availability proofs.

Chengming Technology issued a letter holding ZCode accountable for uploading data without authorization

Taiyuan Chengming Technology Co., Ltd. sent a letter to Beijing Zhipu Huazhang Technology Co., Ltd., raising multiple demands regarding the alleged unauthorized upload of company data assets and trade secrets by its ZCode client, and reserving the right to pursue legal accountability. Chengming Technology pointed out that although Zhipu has publicly apologized for the "silent upload of user local repository data" and claimed to have fixed the issue, independent evidence collection revealed that the upload behavior was automatically triggered and occurred in bulk, including complete archived files such as project source code, system architecture, version control history, database passwords, cloud service credentials, and employee personal information, far exceeding the scope of collection stated in its Privacy Policy.Although the client was updated to version 3.12.3 on September 16, upload behavior was still detected in the early hours of the day Zhipu publicly apologized, raising doubts about the actual effectiveness of the "fix." At the same time, the ZCode client’s network requests pointed to a Singapore entity, while the service agreement was signed with Beijing Zhipu Huazhang, requesting clarification on the responsible party for this upload, as well as whether the data was transmitted abroad or stored overseas.Chengming Technology demanded that Zhipu respond in writing by October 10 and complete the immediate cessation of processing and thorough deletion of all uploaded data and related derivative data, caches, and backups, provide a complete list of processing situations, clarify the data's whereabouts, whether it was shared with third parties, whether it was used for model training, and whether cross-border transmission occurred, explain the management of encryption private keys and complete operation logs, clarify the exact scope of "destruction" mentioned in previous public responses, issue proof of deletion completion, provide a written commitment not to upload without authorization again, legally provide access, copying, and explanation of personal information, and designate formal communication channels, among other matters. Currently, Zhipu has not publicly responded to the aforementioned letter.

There are 106 national embodied intelligence data collection centers and over 5,000 robots

According to a research report released by Tiger Sniff on September 20, as of August 2026, there are a total of 106 publicly disclosed centralized embodied intelligence data collection centers in the country, of which 84 are in operation, accounting for 79.25%. 52 centers disclosed the number of deployed robots, totaling approximately 3,972 units, which estimates that there are at least over 5,000 robots operating in data collection centers nationwide. The peak of construction is expected in the first quarter of 2026, after which new projects will significantly decrease, and the industry will shift from intensive construction to concentrated operation.In terms of regional distribution, Jiangsu, Zhejiang, and Guangdong have 18, 17, and 11 centers respectively, Sichuan has 8, and Beijing has 7. In terms of robot brands, Zhiyuan Robotics appeared 31 times, Leju 15 times, UBTECH 13 times, and Yushu Technology and Galaxy General each 10 times. 65.96% of data collection centers use a single robot brand, while 34.04% adopt a multi-brand strategy, and cross-entity data reuse remains a challenge.Regarding data pricing, the current real machine data costs about 500 to 1,000 yuan/hour, UMI and other non-entity data costs about 300 to 400 yuan/hour, and simulated synthetic data costs about 200 to 500 yuan/hour, with remote operation collection accounting for 79.05%. The report points out that centralized data collection has not yet formed a stable commercial closed loop, with buyer growth lagging behind base expansion. Centers that primarily rely on one-time construction funding will face greater operational pressure, and the industry elimination race has already begun.
