|Crypto currencies based on directed acyclic graphs (e.g. IOTA) seem to solve nearly all of the biggest problems with blockchains -- scalability, low or 0 transaction costs, no 51% attack, no need for miners.|
DAGs cannot be used for generalized smart contracts, so they are not a competitor for Ethereum. But do they have any disadvantages as compared to Bitcoin and other pure cryptocurrencies?
I assume I'm missing something, because otherwise DAGs seem too good to be true. And so far there has been little attention paid to them by the crypto ecosystem.
