What is Fasttoken (FTN)? FTN is the native coin of Bahamut - public, layer 1 EVM-based blockchain solution with a novelty consensus - PoSA. PoSA stands for Proof of Stake and Activity, where Activity is represented by the amount of gas spent by users when interacting with a validator-deployed smart contract. The more gas usage the given smart contract has, the more chances for the validator-deployer to become a block producer in future epochs.
