Btw iota uses PoW, not PoS
This is what a person with a low IQ and/or incomplete understanding of the holistic analysis of block chain consensus would conclude.
Rather Iota actually devolves to either a proof-of-reputation or centralized proof-of-work because of the loss of the Nash equilibrium which I explained upthread, thus forces centralization in order to force convergence over choices of conflicting DAG branches. How this centralization is maintained will determine whether it is via reputation of which servers payers and payees trust (if these servers can sign these transactions somehow perhaps) else devolves to who has the most efficient ASIC mining farms same as for Bitcoin.
