first_img DeepSeek open-source Ascend basic components, covering compilation, computation, and communication libraries

The artificial intelligence company DeepSeek has officially open-sourced infrastructure components for the Huawei Ascend computing platform, covering the TileLang high-level language compilation tool, computing libraries, and distributed communication libraries, corresponding to the previously open-sourced components for the NVIDIA platform. TileLang aims to provide a general-purpose, simpler programming language that can achieve the hardware performance limits, improving development efficiency and simplifying logic compared to CUDA, while its programming model can also leverage chip features.The TileLang route was first validated on the NVIDIA platform and has already supported the implementation of most operators in the training of the DeepSeek V4 series models. The open-sourced Ascend version encapsulates the underlying instructions of the Ascend C, providing a high-level programming approach without sacrificing hardware performance. Currently, every TileLang operator used in DeepSeek's training has a corresponding high-performance implementation on Ascend.The components open-sourced at the same time also include DeepGEMM, DeepEP, TileKernels, FlashMLA, and DeepSelect, which are used for general matrix operations, large-scale cross-device communication, conventional vector calculations and memory access, long-context sparse attention, and data filtering, respectively. DeepSeek claims that in multiple key tests, the related computing and communication performance has approached hardware limits; during the R&D process, the Huawei team provided support, and both parties collaborated to advance the 128-card supernode solution based on Ascend 950, with deep optimizations made for computing and communication.

Satellite communication infrastructure company Space Network has signed a binding pre-purchase agreement worth $50 million with Philippine infrastructure company HQ Company International Holdings to provide satellite connectivity to the Philippines through the low Earth orbit satellite network Freeport. The signing ceremony was held at SKY 31 in Seoul, attended by Space Network CEO Tae Lim Oh and HQ Company CEO Yongsoo Samuel Cho.According to the agreement, Space Network will provide access to the Freeport network, technical hardware, software, and ongoing engineering support, while HQ Company will be responsible for local sales, customer acquisition, spectrum authorization, and regional service implementation. Cho is the son-in-law of former Philippine President Fidel V. Ramos and has long been engaged in cross-border investment and infrastructure business in the Philippines. This agreement adds to the $100 million agreement signed by Space Network with Vietnam's DETI Technology in June 2026, bringing the total commercial pre-purchase amount to $150 million.Freeport is built and operated by Space Network, currently featuring 4 low Earth orbit satellites, with plans to expand to approximately 230 satellites by the time commercial services launch in 2029. Operators can purchase regional capacity and build their own services on the open network, with nodes settling through on-chain contracts. The related project Spacecoin combines blockchain protocols with low Earth orbit satellites for service pricing and payments within the network.

first_img Zcash released Udon, incorporating the Tachyon scaling code into Zakura Common

According to CoinDesk, Zcash developers are integrating part of the proposed scaling upgrade code, Tachyon, into the software already in use to prepare for a large number of privacy transactions in the future. This component is named Udon, originally developed as part of Project Tachyon.According to Sean Bowe, the head of Project Tachyon, Udon was released on Monday to Zakura Common, which is a cryptographic library shared by Zakura and other Zcash projects. Common is responsible for handling some of the heavy mathematical computations behind creating and verifying privacy transactions, with Zakura being jointly developed by Bowe's team and Dev Ojha's Valar Group.Zcash wallets need to prove the validity of a privacy payment without disclosing the payer, payee, or amount, and the computers running the network subsequently verify that proof. According to CoinDesk's report in August, previous improvements to Common have reduced the time to create a privacy transaction from over 3 seconds to under 200 milliseconds in some tests.If privacy payments become more common, these computers will need to handle more data. Udon brings some of the computational requirements for the proposed scaling upgrade of Tachyon into Common, allowing developers to continue building on the already accelerated code. Udon has been released as software, but the upgrade has not yet been activated on Zcash.Bowe and Ojha's long-term goal is to exceed 50,000 payments per second. At this rate, they estimate that current cryptography will allow each Zcash node to receive over 500 MB of data per second.
