DeepBrain Chain Progress Report #117 08.16–08.31(2022)

Dear DeepBrain Chain community members,

Please see below for the latest update on the project.

I. Product Development Progress

GPU Cloud Platform:

• Added the Alipay purchase function to CongTu Cloud;
• Optimization of TeuringCloud cloud platform page content display;
• Further optimizated the NODEJS server code;

Distributed Computing Network:

• Implemented and tested the CPU equalization and binding;
• Implemented and tested single GPU leasing for dbc;
• Integration of a new interface on the chain for single GPU leasing is currently being tested;

DeepBrain Chain Mainnet:

• Improved the mainnet single GPU rental logic;
• Changed the type of rental time to “block height” and the calculation method of rental time is the weighted average of the number of GPUs in the order;
• Optimized the performance of the check of the rental order to be confirmed at the time of rental to trigger once when it reaches a specific block height;
• Optimized the serialization of bytes results to strings in RPC;
• Cleaned up expired storage that triggers execution logic at certain specific block heights;
• Fixed the bug that triggered penalties were not recorded in some cases;
• Fixed the bug that the status at the end of the lease is incorrect when the machine’s GPU is leased by different orders;

II. Marketing Progress

• DBC computing mainnet has been officially launched, as of August 31st, 2022 Singapore time, the GPU in the mainnet of computing power has reached 2,562, halfway to the goal of 5000 GPUs. The latest data on the chain is: there are 19 computing pools participating, the total computing value reached 675,206.27, these GPUs pledged a total of 257,375,000 DBCs, the GPU rental rate reached 66.93%, and the accumulated rental income reached 1,575,669,127 DBCs, please refer to the official website for details: https://galaxyrace.deepbrainchain.org/;
• Continuously improve information about DBC on Xangle, synchronized the progress of DBC ecosystem construction (including cloud platform development, community governance, etc.).
