This is the unlocker of the pool.
We already outsourced it to an own server, but the geth has problems as it seems from time to time.
Changed the machine to an other server within our cluster now, perhaps it is now more stable.
Good news, we found a new teammate to take care of the development and pool operations.
He is a node.js and golang developer, and already as @shogun in our discord chat
https://discord.gg/nuzaNzp now.
Now we are going to work on a complete own draft of pool software for minerpool.
This will solve some problems the open-source software has and will bring a new frontend with additional features to the minerpool miners.
Cheers
Chris
