How can Toucan be sure that people won't retire credits that they convert to BCTs but also use (in the real world) to offset — i.e. double use them?
Retirement Beneficiary: the Ethereum account that will received the bridged batch of credits. Retirement Reason: "Other" — indicating that the credits are not being retired "for a Person or Organization" or for "Environmental Benefit". This field is crucial to make it clear that these retired credits cannot be used for carbon neutrality claims, as this would constitute double usage. Retirement Detail: A cryptographic reference to the "BatchNFT", the digitized representation of the batch being bridged stored in a non-custodial smart contract operating on the Polygon blockchain.
