Ethereum utilizes a different operational logic — this also includes confirming transactions. As a proof-of-work network, Ethereum requires many decentralized nodes to reach a consensus on whether to allow a transaction or not — as well as miners to create new blocks. This goes both for daily use of the blockchain and mining operations. For every transaction, miners receive rewards as transaction fees. There are also operational costs or so-called gas fees. EOS and Telos rely on a delegated-proof-of-stake mechanism. Meaning, all elected 21 block producers chosen from most voted for major EOS or TLOS holders, are in charge of the network’s operation. EOS and Telos cannot be mined, and so resources consumed by those blockchains come from the tokens staked by users — or through the Power Up function. By default, Wombat covers 10 free actions on EOS and 20 free actions on Telos. Please keep in mind that we do not cover transaction and gas fees on Ethereum.
