What's the difference between EOS and Ethereum? Why have you chosen EOS?

Ethereum is largely just a smart contract platform, with a token standard.

Emanate is aligning with EOS because of the vision that they have for multi-purpose programmable nodes, for fee less transactions and for throughput of over 100,000 transactions per second.

While EOS is still in early beginnings, Ethereum has failed to scale even with unlimited resources, thousands of developers in the community and over 2 years on the mainnet.
