In May, Diode’s CTO Dominic Letz published a paper introducing BlockQuick, a super light client protocol for blockchain validation on constrained devices. The paper shows that unlike other existing approaches such as proofs of proof-of-work (PoPoW) and FlyClient, Diode’s BlockQuick super light client protocol is capable of protecting against eclipse attacks and man-in-the-middle attacks on a peer-to-peer network. But what is an eclipse attack? Is it possible to prevent some of blockchain’s biggest security threats?...
