 - All currently supported wallet user experience should continue to operate seamlessly without change during or after protocol transitions. This covers the use of addresses, payment flow, transfers, ZEC supply cap and issuance rate, backup/restore, and other features users currently rely on.
 - There must be no security or safety degradation due to wallet user behavior introduced by PoS transitions, assuming users follow their current behaviors unchanged and continue to use the same cognitive model of the impacts of their behaviors. This goal encompasses all of security and safety, including privacy and transparency or more explicit disclosures.
 - The protocol should enable users of shielded mobile wallets to delegate ZEC to PoS consensus providers and earn a return on that ZEC coming via ZEC issuance or fees. Doing this may expose users to a risk of loss of delegated ZEC (such as through “slashing fees”). The protocol must guarantee that PoS consensus providers have no discretionary control over such delegated funds (including that they cannot steal those funds).
-- For any hybrid PoW/PoS protocol (including the PoW+TFL protocol we’re proposing), the process and UX of mining remains unchanged except that the return on investment may be altered. This is true both of consensus level block miners (ie mining pools and solo miners) and mining pool participants.

 - Any hybrid PoW/PoS protocol (including PoW+TFL) block explorers will continue to function with the same UX through transitions in-so-far as displaying information about transactions, the mempool, and blocks.
 - Block explorers and other network metrics sites may require UX changes with respect to mining rewards and issuance calculations.
 - Network metrics sites may require UX changes with respect to the p2p protocol or other network-specific information.
