3.5 FID and On-chain Reputation

Each Soul Account is assigned an FID (Fire Identity), which serves as the on-chain identity ID for the official DAO member, displaying their on-chain identity information and being linked to the Soul Account. Different SBTs have different weight coefficients, and by calculating the quantity and weight coefficients of different SBTs in the Soul Account, each FID will be assigned a "composite reputation score", which represents the "on-chain reputation" of that FID.

"On-chain reputation" will exist in the form of an independent ERC20 token, with its token symbol being FRT. Whenever there is a minting or burning behavior for any of the 7 SBTs, FRT will be minted or burned synchronously. Ultimately, the number of FRT in a user's Soul Account will serve as the weight used for voting in governance.
