Blockchain.io platform will serves as bridge between blockchains powered by Bitcoin, Ether and other cryptographic protocols. Miners will solve sophisticated puzzle in order to validate transaction. All these activities will be iterative. Provision will be made for crypto currencies to be traded against fiat money.
The project has great potentials and also has real life use cases. I am convinced the project will be widely adopted due to it problem solving nature. Besides, the project is being pursued by individual whose are experts in their respective field. Having developed a similar system (i.e. Paymium) indicates the project is already a success.
