f2pool was previously Grin’s largest mining pool, with roughly 50% of network graphrate if I remember correctly. Since the announcement many miners have already migrated to goplinpool, which at the time of writing has 70% of network graphrate.
I am the creator of goblinpool and a member of grin community since 2019.
we will never do attack to grin network, and open to community to find a way to decentralized the hashpower.
Here is the specific action we will and take:
we will increase pool fee to encourage miner to other pool.
we contacted grinmint pool , and suggest to setup hongkong server, and already help them to translate to chinese version （http://cn.grinmint.com）.
And since most grin miner in mainland china, we suggest every miner pool should setup a mainland china server.
Probably because @xiaojay has been involved with Grin for a long time, developed a popular GUI wallet, and is one of the most trusted people in the Grin community- Especially the Chinese community where most of the miners are based.
Per Miner. Fee for example https://grin.2miners.com/ There are 35 miners currently mining Grin. If only everything could be limited only the maximum submitted hashrate of 1.4 Gps (just for example).
Can the miner be limited to only using the local internet network in their country? For example, you can’t use a VPN and have to setup a dedicated static IP? Something like that to limit it. It’s okay to have multiple accounts originating from the same (human miner).
Or what is the scenario in the real world about this that has been practiced? This is what I asked you, because I am very unfamiliar about this. Thank you for responding and enlightenment.
No; those are mining accounts. You have no foolproof way to determine if these are 35 unique individuals, or one individual using 35 different accounts. If you limit the amount of graphpower per mining account, then you’re just forcing large miners to create more accounts.
to help the network stay Decentralized use smaller pool please
also i think the grin explorer need more option like network hashrate and a graphical chart to see pools hashrate and miners count

I justed visited the Grinmint website, and the pool says it is shutting down!
Is this really true, or did someone hack the website or so?
It is with great sadness that we are announcing the end of Grinmint. We are really grateful to the miners and the Grin community for trusting us for more than 2 years.
We encourage miners to switch to another mining pool and withdraw their payouts as soon as possible. Please note the following dates:
- On June 21, the stratum server will be stopped.
- On July 7, the website will be shut down.
Quentin wrote this on keybase yesterday, so it’s true
Ok, then it is true . A pity, but I can understand that for them this might be a necessary economical decision. We can be thankfull to @quentinlesceller and Block-cypher for helping the Grin projects for such as long time with Grinmint, your support will not be forgotten .
@noobvie servers might be in the order of 150 - 300 eur / month at least in the EU. But then there’s the software itself and support, I don’t know whether there’s any suitable open source grin mining pool. Building one from scratch would be a lot of effort.
