A new block is released every 15 seconds.
Proof of Work
Users pay transaction fees and miners collect them alongside with the block reward based on work done as per the proof-of-work (PoW) mining algorithm. Specifically, the consensus requires miners to solve a mathematical problem using computing power to validate new blocks.
Ethereum Virtual Machine
Ethereum Classic features an execution engine optimized for smart contract processing known as the Ethereum Virtual Machine or EVM.
Ethash is an Ethereum mining Proof-of-Work algorithm designed to be ASIC-resistant through memory hardness and easily verifiable.
