Oops We Did It Again: DeroGold Mining Pool on OrangePi 3

Oops We Did It Again: DeroGold Mining Pool on OrangePi 3

A few months ago we announced our public minining pool for TurtleCoin that runs on OrangePi One Plus.

As this project was not enough, we stepped up to the challenge and recently set up a new pool for another privacy coin project in which we are involved – DeroGold.

Doing a pool for DeroGold is a bigger challenge. Why? One of the main reasons for that is DeroGold at the time of writing has 20 seconds block time. Keeping up your nodes synced with blockchain could be a challenge, and on a lower spec hardware you need to understand what you’re doing, as well as be able to do some basic performance troubleshooting & tuning.

It took us a few weeks to come up with a concept of building a really sturdy and reliable cluster of nodes to serve our DeroGold mining pool fast and reliable. We use haproxy loadbalancer to actively load balance between DeroGold nodes, and monit to monitor and recycle stuck or crashed daemons.

Lesson’s learned: DeroGold to cope with 65k+ transactions in the tx pool

There is no attack in a decentralized privacy network. It’s just either regular transactions or fusion transactions.

Of course, there could be elements and individuals who would deliberately perform such activities that would cause some degree of a trouble for a young distributed, decentralized network that consists mostly from unmanaged low powerfull nodes.

And that was exactly what happened to DeroGold a few months ago. One day we woke up in the night looking at network & node monitor. Hash rate down, pools mostly not operating, alternate chains on the network, only about a 4-5 nodes respoding and keeping up.
