Thanks Dana for explanations. That will help me.
Let me comment on your suggestions:

• SAFE Network is not blockchain technology at all. AFAIK you will never be able to observe the whole state of a network.
• Storj is just a protocol on top of Bitcoin and Counterparty for storage of immutable chunks of unstructured data. Its not about transactions at all.
• Sia is designed to have very simple set of smart contracts which allow to do the same thing as Storj is intended for. It allow to transact only using core token.
• Filecoin based on IPFS exist only on Juan's paper. I didnt hear about any implementation.
• Iota is a quite new beast and I don't understand nor how it works neither what it is best for yet. AFAIK Jinn is a hardware chip with ternary logic with the same people behind.
• I was not able to find Solid on Github. I am interested in open source only.
• Thanks for Ceptr. Will look into it.
