3/ In traditional Web2 FHE use cases, the user holds the decryption key and is the only one who can decrypt the data. However, many Web3 use cases require the decryption key to not be held by a single user, but rather be decentralized across many parties so no one can.

7/ Our scheme is generic: it can work under any t-out-of-n setting and for any FHE scheme. Importantly, we solve a key-issue here with t=2/3 which is commonly used for consensus, and no scheme known to us has been able to achieve a practical, scalable solution for.
