I am almost done with finishing versatile and well know tool for blockchain development to Peercoin - pycoin.
This tool will enable developers to use this versatile tool with Peercoin network. Pycoin can be used for all kinds of stuff, ranging from custom made clients to blockexplorers.
Even Bitcoin books refer to it: https://www.safaribooksonline.com/library/view/mastering-bitcoin/9781491902639/apc.html
I think it is necessary to have this in our portfolio to attract new developers.
Please support development with donations or help with patches.
