There are many differences between Antelope and Ethereum blockchain. First, the two networks use different consensus mechanisms. Ethereum uses Proof of Stake (PoS) to reach consensus and Antelope blockchains utilize Delegated Proof of Stake (DPoS). There are many advantages to DPoS as a consensus mechanism including higher transaction speeds, increased throughput and quicker finality.   The two networks utilize different smart contract languages at the base layer, with Antelope utilizing C++ and Ethereum utilizing Solidity. C++ is arguably much more performant for executing functions and contributes to the higher capacity of Antelope smart contracts, when compared to Ethereum.
