Minting Certificates: After the issuance of the certificate, the system mints the certificates as
ERC1888 tokens using ERC1155 (through the
Issuer.sol
file code and
Privateissuer.sol
),
which represent the renewable energy attributes (e.g., 1 MWh of green energy). These tokens can be
traded or transferred, providing a transparent and verifiable record of green energy consumption.
