I thought that Iota-coin have a lot of common with Ethereum, but I hae found that it do not have support of smart-contracts. I googled about what was there reason of do not implement it (I really thought that smart contracts is future) but I found only one mention about it:
"Iota itself cannot implement smart contracts cause there is no consensus on state finality and each node has its own personal view of the state, rendering unusable for distributed general purpose computation."
Does smart-contracts have any issues? Or What?
