Move to balance model?

[tijno]

I noticed mentions of the move to balance model by @redpartyhat

This will be a manageable and temporary increase in storage that will be relieved when CLOUT is moved from UTXOs to a balance model.

And @diamondhands0 here:

But even then it's not a big deal because we'll move to balance model shortly.

And in the code here:

deso-protocol/core@b823978#diff-7fc2e28969d594902d8507b410e849b6feef5e285e57162f5b81f5c26241fca3R479

type PGBalance struct {
 	tableName struct{} `pg:"pg_balances"`

 	PublicKey    *PublicKey `pg:",pk,type:bytea"`
 	BalanceNanos uint64     `pg:",use_zero"`
 }

As this is a protocol change - should this not be a CIP?

Specifically I would be interested to understand:

• will UTXOs be removed completely?
• pros & cons
• impact on scalability
• risks for community developed tools

I can see positives for sure - eg it will be easier accounting, easier to determine total clout in circulation, and reduce size of the chain.

I would love change to the balance model. UTXOs are hard to read and take a lot of space in the calls (for example mempool call).

Looks like this has moved to DIP?
