Decentraland (MANA) is currently based on cryptocurrency Ethereum protocol. You can trade this digital asset on the fair number of exchanges. For example, Binance features MANA/BTC currency pair.
EOS is an innovational blockchain-based ecosystem promoted as an alternative to Ethereum due to a similar set of features. It was founded in 2017 by a company block.one. EOS is a platform for hosting of decentralized applications which provides developers with a rich choice of functions and services. The platform uses a native token of the same name, EOS.
EOS is aimed at the total removal of the transaction fees and limitless network capacity reaching millions of transactions per second. At the same time, there is still much work to do. The governance model of this platform is quite unusual. Instead of anonymity, EOS relies on the popularity and responsibility of elected independent block producers. The protocol is known as delegated-proof-of-stake.
