Some time passed since I heard really something new about sidechains as a solution to the scaling problem. The technology seems to be "stuck". This article from January about NiPoPoW is one of the few news about the topic I saw lately.
I'm curious what the current state of the art is. Are there people here that know where I could search and look at, to know more about the current sidechain discussion? Are there active projects, e.g. working on testnet?
I know that Rootstock and Blockstream have implemented federated sidechains, but they're too centralized to be really called "solutions", for me. What I'm more interested in are (almost) trustless designs like Paul Sztorc's Drivechain.
