So, is Marlin like libp2p?
Yes and no. Marlin is similar to libp2p in that we do provide networking libraries that can be used by P2P projects to enable decentralized communication between their nodes. However, we widely differ in our focus and approach. We posit that substantial performance improvements and spam prevention requires monetary rewards and penalties in the form of staking, slashing and payments - a perspective that doesn't seem core to libp2p's roots.
