Gas
A unit measuring the computational effort required to execute operations on a blockchain. On Ethereum, gas is priced in gwei (10^-9 ETH) and varies with network demand. Users set gas limits and gas prices; unused gas is refunded. Solana uses 'compute units' as its equivalent, with much lower costs (~$0.00025 per transaction vs. $1-100+ on Ethereum).
