Filecoin Space Race Update: Unlocking FIL Prize Pool and 6Block Sharing at the Filecoin Miners Webinar

Four days into the Filecoin Space Race, we have seen over 300 miners participating in the race, with a total raw byte storage power of 36 PiB, unlocking 300k FIL global prize pool.

As for regional rewards, only Asia, Europe, and North American managed to unlock different levels of prize pools at the writing of this article: Asia 250k FIL, Europe 25k FIL, and North American 25k FIL.

Yesterday, Filecoin invited big miners to share their mining configuration and their stories with Filecoin. Lee White, our core developer at 6Block, shared as one of the panelists. You can watch the full video here. Here is the TLDR:

What is 6block?

6Block is a mining pool that focuses on “unicorn” projects in the blockchain industry. There are many new projects in the blockchain field emerging every day, but we believe that only a few blockchain projects have value and potential, so we want to invest our resources in projects that can truly change the world with technology.

When did 6Block start working on Filecoin mining? started to study Filecoin mining during the Chinese Spring Festival this year. It has been 6 to 7 months now. After running the Filecoin testnet for a while, we started to dive deeper into the technology. Because our team has a strong background in blockchain, especially algorithms and zero-knowledge proof-related technologies, and we were intrigued by Filecoin’s testnet, we started the research on Filecoin mining.

What’s 6Block’s Filecoin mining configuration?

We have two types of workers (computing machines), which we named as F3 and F7. F3 is suitable for small-scale clusters, using AMD 3960X processors, which can only adapt to 256GB of memory and is cheaper overall; F7 is our large-scale cluster solution, which is more expensive. It uses server-grade CPU and 1TB memory and is more suitable for large-scale deployment. The storage machine is only responsible for storage.

This is the network architecture of our cluster. We have not adopted a super-large-scale cluster architecture, each cluster has only about 100 machines. Each Miner has only 4 parts (Hub), two are responsible for the calculation and two are responsible for storage.

As the only mining provider that has openly shared its hardware configuration from the day-one, we chose to share our high-efficiency configuration to bring transparency to the community. You can check the configuration and parameters of the relevant hardware on our website at

We have also optimized the software a lot, at both engineering and algorithm levels. For engineering, we have refactored the task scheduling part. This is mainly because many machines involved in Filecoin mining have different configurations, so you must build a task scheduling module that best suits your own hardware. At the algorithm level, we mainly improved PreCommit1 and Commit2, and reconstructed PreCommit2 with OpenCL.

A few days before the Space Race started, 6block has already started to optimize network stability and storage stability, and optimized order priority. Currently, 6Block has not shared our miner id for security concerns. But as we are approaching the last registration deadline of 2200 UTC on Monday, August 31st, we believe you will find 6Block on the leaderboard soon.

Lee’s share has received great feedback from both the Protocol Labs team and the community. A lot of the Filecoin community has known about 6Block in the Slack group as we often share our technical findings, we are very glad to meet the team and share with the community face-to-face.

Well, that’s all for today. Thanks for reading and happy mining!
