A Bright Green is a token that represents ecological improvement that has been grown by producers (farmers and land managers).
It is a built on the Ethereum blockchain. It combines two types of token. The PIE (Producer Investment Evaluation) Certificate, which proves the work has been done, is held on a non fungble token called ERC1155. The financial value is hold on a fungible token called ERC20. These two tokens are tied together so every Bright Green contains a certificate and specific data proving the genuine ecological improvement that created its value.
Bright Greens are stored in crypto wallets (Ethereum wallets). They can be bought and sold from a wallet.
