Currently, it cannot. Burning and reissuing tokens is possible on the smart contract, though this has not been implemented on the front-ends. Theoretically, upon burn, the KYC/KYB/accreditation information would need to be deleted and then members could sign up with a new wallet.
Yes, this is mandatory. UID is the first NFT for identity. No personally identifiable data is stored on-chain. More on UID here.
Before minting UID NFT, you need to verify your Ethereum address from here: https://app.goldfinch.finance/verify. Please head over to the Tutorials section for a detailed explanation.
You can go back to https://app.goldfinch.finance/verify and sign in. If you are verified, you will see the message - “Your address verification is complete” or “Your verification was approved to immediately access the Senior Pool”.
The protocol must have sybil resistance in order to implement the "trust through consensus" mechanism outlined in the whitepaper. Technically, this does not need to be KYC, and the community hopes to offer versions of this in the future which do not require ID verification. However, KYC offers sybil resistance as well as the legal compliance which many of the Borrowers require for their own purposes.
Note, Goldfinch's KYC/KYB and accreditation is handled by third parties, Persona and Parallel Markets, who, like Goldfinch, take privacy and security very seriously.
UID is completely interoperable. It is a standard ERC-1155 contract, so any protocol can get the benefits without having to build their own KYC flow or handle any data themselves. If you are a builder, check out the docs here to learn how to integrate it.
Because the UID is an ERC-1155 contract, it is not transferable and cannot be sold.
