EOS is a blockchain and a smart contract platform that will directly compete with Ethereum. It is advertised as an operating system for decentralized applications. The platform uses a delegated proof of stake (DPoS) consensus mechanism, which makes a fundamental tradeoff to become more centralized (having 21 block producers rather than an infinite number of miners in a proof of work model) in exchange for a faster, more scalable network.
EOS has a long way to go but do you think that EOS has the potential to beat Ethereum price one day or ETH will still remain king.
Eth has already established its name and there are lots of supporters backing up Eth so I don't think EOS can surpass Eth in the near future. It's possible but not in the near future since Eth has already proven its performance in the market next to bitcoin and the devs behind it is also working hard to do some upgrades that will enhance the technology of the Eth platform.
