Instead of POS (see my previous post), it would make much more sense to adapt the Nimble Wimble approach of making it so that validation is P2P whenever both parties are online. If I buy from you and you agree, then the purchase should been validated with 2 confirmations. Since we both agree that the transaction is made, it’s no-one else’s business if the transaction is valid. This would be much less resource intensive than even POS and be faster. If only one party is online at a time, it should be possible to have 1 confirmation and the other confirmation can be delegated to a miner. If neither are online at the time, then the usual POW takes place. Of course, that would mean that all wallets would have to be validators, but since you’re only validating your own transactions, it should be light weight.
I agree to an extent, but banning from CEXes is the only way for Monero to truly become digital cash since cash is P2P. If everything depends upon CEXes, all Monero has done is replicate the existing financial institution. We might as well adopt anonymous repaid debit cards. It would have been best if this happened after Haveno, Serai, Serai integrating with the Maya Protocol, Seraphis, and FCMP (Full Chain Membership Proofs). But realistically, Haveno was taking forever, as was Serai, and FCMP were supposed to be done after Seraphis, and Seraphis might take 5 years to complete. IMO, because of the pressure with the delisting, Haveno and Serai have accelerated their development as has the interest in using them. FCMP may arrive before the end of the Bitcoin bull run. People from the Maya Protocol have also eyed Serai as a possible hub into the privacy space (since Monero proved that it won’t go away or be bow to regulation) and an integration like the Cosmos integration might be possible, making Monero integration into the whole DeFi world convenient and possible.
