Is the IoT industry the most easier to landing? Connecting everting together require both software and hardware technology.

Iota: tangle technology, seriously they develop tangle but it not blockchain indeed, not decentralized.

ITC: PBFT+DAG, seems like more reliable, DAG solve some obviously problem in PBFT

Vechain: POW+A, I still think POW is not the better choice. we have to upgrade more than blockchain 1.0
