In Short

Makes denominations spendable.
(and spendable multiple times without de-mixing with XPub Send)

The current denomination system donates all non-denominable DASH and provides very small, often non-useful stamp values for fees.

This proposes to carry a higher stamp fee value that is useful for at least one send, and even for multiple sends (in the case that the funds are not de-mixed).

Input	Denom	Current Denom + Stamp	Proposed Denom + Stamp
5.0		-	-
	0.001	9x 100001	9x 103200
	0.01	9x 1000010	9x 1003200
	0.1	9x 10000100	9x 10003200
	1.0	4x 100001000	4x 100003000
		4 self-transactable coins	31 self-transactable coins
		27 non-transactable coins	0 non-transactable coins
		1 mixed transaction	15+ mixed transactions
		98833 DASH dusted	160 DASH dusted

Current denom stamping:

5.000 =>
    9x 0.00 10000 1
    9x 0.0 10000 10
    9x 0. 10000 100
    4x 1.0000 1000

• Spendable Dash: 4.999
• Fee Stamps per Denom: < 1
• Dash Wasted: (0.00049900 + 0.00050010) - 1077 (0.019%)

Proposed denom stamping:

5.000 =>
    9x 0.001 03200
    9x 0.010 03200
    9x 0.100 03200
    4x 1.000 03000

• Spendable Dash: 4.999
• Fee Stamps per Denom: 15+
• Dash Wasted: 0.00000160 (0.000%)

Stamps vs Denominations

This is about the STAMPING of denominations, not the denominations themselves. It applies to ALL denomination schemes.

For example, it can also be applied to a less data-leaky scheme using doubles, wholes, and halves:

5.000 =>
    2x 0.002 09000
    1x 0.005 09000
    2x 0.020 09000
    1x 0.050 09000
    2x 0.200 09000
    1x 0.500 08800
    2x 2.000 08800

In the example you gave, the Dash is not 'wasted', when we denominate 5 Dash, we wind up with 0.00095001 Dash in change, this is kept in the wallet to pay for collateral fees which cost 0.0001 Dash. Also, using the optimised denomination you propose, may better spend the funds, leaving just 160Duffs spare, however, note that those 160 Duff would not even be enough to cover the transaction fee of the denominate transaction.

Mixing is not a value add to the Dash network, but rather a profit centre. The fees paid during mixing are shared in proportion with the miners and the masternodes, there simply is no concept of Dash being wasted, it is used to support the network.

160 duff is donated in with the fees.
(though that particular calculation was inappropriately rounded, so it's more like 147 or 173 - I'd have to update and run it again)

My example is wrong about the change then. I misunderstood. I can change that.

We'll have to define "profit". It pays for the cost of electricity and virtualized hardware and storage for the masternode network to run and has excess?

This is part of a series of DIPs that can be accepted independently, but work in concert.

It's necessary to have stamp values high enough to self pay in order for XPub Send (Cash-Like Send) to be viable. #132 is also necessary.

[coolaj86]

To be clear:

10003200 => 10003000 => 10002800 => 10002600, and so forth.
(though doing so would require XPub send, otherwise it would get de-mixed on the first go)

You can transact one of those coins at least 15 times.

That's using a typical example of receiving whole dash from pay and then mixing it. If you were to mix change you've received or a taxed payment, then it would be different. It could be worse, but not better. You could calculate probably 50% of that on average - so on average a coin would have enough change to spend it 7 times.
