Dear DeepBrain Chain community members,

Please see below for the latest update on the project.

I. Product Development Progress

GPU Cloud Platform:

  • Addressed multiple bugs in the cloud platform;
  • Supported the deployment of GPU cloud platforms in multiple countries;
  • Development of a monitoring platform that can view real-time information on GPU, memory, CPU and many other machine parameters;
  • Development of business management backend;

Distributed Computing Network:

  • Addied modifications to the HTTP interface of the virtual machine configuration;
  • Optimized the validation of request parameters in the dbc program;
  • Integrated the NVIDIA management library (nvidia-management-library) into the qemu guest agent to make a dbc-guest-agent, imitating nvidia-smi, so that the dbc program can monitor the GPU information inside the virtual machine;
  • Optimized the transmission speed of virtual machine networking using the VXlan solution;

DeepBrain Chain Mainnet:

  • Updated Polkadot App dependencies to the latest SDK, fixing compilation issues;
  • Refactored the penalty execution logic in some Hooks to specific block triggers, optimizing performance;
  • Increased the rental length limit to a maximum of 60 days from now;
  • Built-in chainSpec and bootnode added to the mainnet, no need to specify additionally;

II. Marketing Progress

  • Progress of Galaxy Race Public Test:

DeepBrain Chain computing mainnet has been officially launched, as of March 14th, 2022 Beijing time, the latest data on-chain: a total of 17 computing pools participated, providing 1,420 GPUs, the total computing power value reached 307,132.1, these GPUs pledged a total of 144,915,000DBC, the GPU rental rate reached 78.87%, and the accumulated rental income earned reached 493 ,887,167DBC, for details, see the official website.

  • The plan to open the DBC(NEO) manual token switch again has been officially released to the community, and users are continuously reminded on Twitter, official telegram groups and other community platforms. The token switch application can be sent in starting from March 14th. Details of the program can be found at:
  • The council held the third meeting to discuss the implementation details of the council meeting process and whether to activate the token destruction of the Galaxy Race early, etc. The minutes of the meeting can be found at:
  • In the past two weeks, a number of candidates have released their election manifestos in our official reddit community, and some of them have made AMA announcements in the official telegram group.

Candidates’ election manifestos:

AMA Recap:


Candidate-Fastwalker — Nexui Communications:

  • A new proposal entered the referendum stage, the content of which is to lower the threshold for the Galaxy Race to open token destruction, namely: lower the threshold from 5,000 GPU to 500 GPU, details of the referendum can be found at:
  • According to the data on the blockchain, the number of pledged DBCs on the mainnet reached 782.94 million, and the pledge rate reached 18.0%, breaking a new record high, for more information, please see:
  • Hillstone Partners (CEO Ra-Yeol Hwang) announced on March 2nd that it will join the DeepBrain Chain (DBC) ecosystem to build infrastructure for the Korean metaverse and AI industry, with the entire investment going towards building a GPU-based high-performance cloud computing pool infrastructure. /2022031012174315508

III. Ecosystem Building

  • The total number of GPUs in the mainnet of computing power has increased to 1,420, with a comprehensive occupancy rate of 80%;
  • The recent decline in the occupancy rate of the whole network is a normal market phenomenon, the occupancy rate will be improved with the entry of many cloud platforms to the mainnet of computing power, but the fluctuation will still exist in the short term;
  • The building of overseas computing nodes continues, and will be promoted in April in conjunction with other projects in the blockchain industry; offline promotion activities will be organized in the UAE and other regions in the second quarter this year, partners in the ecosystem are welcome to actively participate;
  • In order to ensure the rental rate of your DBC computing nodes, please follow the recommended configuration and GPU model of the mainnet when launching online.
