Hey there, this information is incorrect. GoChain will have its own blockchain. It's testnet is already capable of processing 1,300 transactions per second, 100x more than Ethereum's 13 transactions. GoChain will solve problems with the current infrastructure by utilising the Proof of Reputation consensus algorithm in order to achieve higher rates of decentralisation (10x) and a massive reduction (1,000x) in the usage of power. As our network is compatible with Ethereum, developers will be able to easily 'lift and shift' over to the GoChain network.
Feel free to check out the Whitepaper and get back to me -- you should be able to see the benefits of using GoChain!
