What does "Gas" mean and what is it for?
While designing Ethereum's Virtual Machine, Vitalik Buterin called transaction fees "gas" or "gas fees", because it make transactions run, just like gas powers cars. This term is in use in other blockchains, as everyone got used to it.
In TON, gas fees are 5-20x cheaper than in other blockchains thanks to parallelism and exceptional scalability. In 2024, TON validators agreed to lower gas fees by 60%, and TON developers are thinking about how to make them even lower.
