Inventory of P2P Java Library to build blockchain application

[fellahst]

With the emergence of cryptocurrency, P2P is regaining a lot of interest recently. Back in 2001, JXTA was aimed to be a general framework to develop p2p application. Unfortunately, the project died after Sun acquisition by Oracle. 17 years later, I am looking to make an inventory of P2P Java libraries to build a blockchain application. I would appreciate if you could provide some pointers.

LibP2p seems a very promising library. Unfortunately there is only an implementation in Go and Javascript. I am planning to implement a Java implementation. If anyone is interested let me know.
