Similar to Ethereum and other Layer 1 blockchains, IoTeX employs a gas fee model, where “gas” is paid by users in proportion to the computational capacity required to process a transaction or smart contract. Unlike other blockchains, the “users” of the IoTeX platform are not limited to only people, but also machines/devices. In the IoTeX Network, both humans and machines/devices will have the ability to send payments, access smart contracts, and even charge for services. Machines will be equipped with wallets (just like a human user) and execute automated payments, data transfers, and more based on pre-programmed smart contracts.
