Although bitcoin and Ethereum have posted solid gains lately, altcoins have gained significantly more. One the biggest stars of recent weeks is EOS, which has been closing in on the $20 mark and has cleared a $15bn market capitalisation. Much of the hype surrounding EOS is to do with the imminent release of its mainnet, which is being touted as the “Ethereum-killer”. if that sounds familiar, well, it is. Just a few months back both Stellar and Cardano were labelled Ethereum-killers; before that, Lisk enjoyed the same epithet. Unlike Ethereum, which operates a proof-of-work consensus mechanism, EOS will launch with a delegated proof-of-stake system instead. Jargon aside, EOS is basically leveraging the developments that have taken place in the crypto world since Vitalik Buterin first proposed Ethereum back in 2013 in order to deliver a more scalable platform for launching decentralised applications. Of course, until EOS launches its mainnet, its potential to take market share away from Ethereum is pure speculation.
