p2poolv2 was discussed at length on delving this last week #1613924, and now here is a version of p2poolv2 launched on the brand spanking new testnet5 #1611539

Watch it run: the testnet5 chain explorer shows the tip, the shares, and who mined them, and the pool metrics show hashrate and effort into the current block.

Come help with the pool design on our Matrix chat, or take something off the project board to help build the pool.

p2pool runs a [sharechain(https://docs.p2poolv2.org/architecture/sharechain.html) that keeps tracks of each miner's shares and includes some information from the bitcoin mainchain. Their website has a lot of documentation about how this works and what the purpose is. They also have a page comparing p2poolv2 to SV2 and DATUM.
