Supply, Reserves, and Equilibrium (superseded by automation)

Will change to this after [Passed] Outstanding Nubits passes. currently the calculator gives a more conservative result (circulating - 15% - nusafe )

Sure, it’s the same either way (no market action). I just wanted to post the example for the future. Specifically the peercoin stuff.

Besides, are we counting sharedays or not with motions? There’s no protocol change needed.

@mhps as a result of these liquidity operations, I now have 26.04 shareholder BTC in my possession.

This calculation is done without any change from [Passed] Standard and Core which passed in the last week. The numbers presented in this calculation will be used to discuss standard-and-core implementation.

Of the 742015.019400 NBT in circulation, 15.00 percent (111302.252910 NBT) plus NuSafe are reserved and excluded from the share buyback calculation (309.764672 BTC).

197.509866 - 309.764672 = -112.254807 BTC in the share buyback pool.
The Standard is 5.00 percent of this, -5.6127 BTC (~ -2560.31 USD)

Buyback pool is not positive. There will be no NSR buyback or PPC reserve filling next week.

The following would be how buyback/refill calculated according to [Passed] Standard and Core Please check.

Circulating NuBits (CN) = 742015.019400 NBT
BTC target (BTCTR) = 15%
reserve target = CN x BTCTR = 111302.25291 NBT
reserve velocity (BTCV) = 5%
The standard (ST) = reserve velocity x (T4BTC - reserve target) = 0.05 x (T4BTC - 0.15 x CN)
= 0.05 x (131.743468 BTC x 456.16 USD/USNBT - 0.15 x 742015.019400 NBT)
= -2560.31

ST < -2500, sell |ST| amount ($2560.31) of NSR

T4 reserve in PPC (T4PPC) = 0
PPC target (PPCTR) = 5%
PPC velocity (PPCV) = 10%
PPC threshold (PPCTH) = $1000

auxiliary reserve flow (F) = (PPCTR / BTCTR) x (PPCV / BTCV) = (5%/15%)x(10%/5%) = 2/3

PPCTH x F = $1000 x (2/3) = $666.67

Since ST(-2560.31) < -(PPCTH x F), sell (F x ST = -1706.83) amount of PPC (oops we don’t have any PPC)

Peercoin standard (PPCST) = PPCV x (T4PPC - PPCTR x CN) = 10% x (0 - 5% x 742015.019400) = -3710.075097

PPCST is not > PPCTH($1000), there is no selling PPCST amount of PPC

Two things: firstly, the outstanding nubits motion passed and will keep us under nsr dilutions this week.

The standard is -$2560.31+(0.15×.05×30k)=-$2335.31
No dilutions will occur this week.

Secondly, you did the ppc stuff wrong. Ill explain when i have some spare time.

Crap, I messed up the motion. It’s supposed to be PPCTH/F not PPCTH*F. The idea is that you take the standard and multiply it by the flow. Then you compare that to the threshold and if it’s bigger you take that modified amount to market. As is it doesn’t really make sense.

We should be bringing $1556.87 worth of ppc to market if we had any. This is over the $1k threshold.

when? in [Passed] Outstanding Nubits it still says voting. the explorer has been down.

No one checked when voting.
Will be traveling. Get back to this later.

Are you counting share days? I’m not a fan of counting SDD for motions. Anyway, alix doesnt really say if a motion has passed or not, so honestly i dunno.

Is it just me or is it a real issue that we can’t figure out if a motion has passed or not?

Well, if you want to do it by RPC, you have to test a lot of rolling windows.
Or you parse the blockchain systematically for it (and note the block at which the motion passed; that can be verified by RPC easily) - I don’t have the skill to do that.
What I’m trying to say is: it’s not just you…

By block 862642 both motions were passed in voting and SDD. This was on Friday May 6th over a week ago. Therefore, I will press forward my standard (-$2335.31) as the official correct one for this week.

Check the following -

this would be how buyback/refill calculated according to [Passed] Standard and Core

Circulating NuBits (CN) = 742015.019400 NBT
NuSafe=30000
Outstanding Nubits = CN - NuSafe = 742015.019400 - 30000 = 712015.019400 NBT
BTC target (BTCTR) = 15%
reserve target = Outstanding Nubits x BTCTR = 106802.25291 NBT
reserve velocity (BTCV) = 5%
The standard (ST) = reserve velocity x (T4BTC - reserve target) = 0.05 * (131.743468 * 456.16 - 106802.25291)
= -2335.31

ST < -2500, sell |ST| amount ($2560.31) of NSR
ST > -2500 There will be no NSR buyback.

T4 reserve in PPC (T4PPC) = 0
PPC target (PPCTR) = 5%
PPC velocity (PPCV) = 10%
PPC threshold (PPCTH) = $1000

auxiliary reserve flow (F) = (PPCTR / BTCTR) x (PPCV / BTCV) = (5%/15%)x(10%/5%) = 2/3

PPCTH / F = $1000 / (2/3) = $1500

Since ST(-2335.31) < -(PPCTH / F), sell (F x ST = -1706.83) amount of PPC (oops we don’t have any PPC)

ST x F = -2335.31 * 2/3 = -1556.87

Since (ST x F) < -PPCTH, sell -(F x ST) = -1556.87 amount of PPC next week (actually since ST < 0 so there is no selling.

Peercoin standard (PPCST) = PPCV x (T4PPC - PPCTR x CN) = 10% x (0 - 5% x 742015.019400) = -3710.075097

PPCST is not > PPCTH($1000), there is no selling PPCST amount of PPC

Of the 743972.860700 NBT in circulation, 743972.860700 - 30000.000000 = 713972.860700 NBT are outstanding.

15.00 percent of outstanding Nubits, 107095.929105 NBT (242.575633 BTC), are reserved and excluded from the share buyback calculation.

199.694407 - 242.575633 = -42.881226 BTC (88164.082365 - 107095.929105 = -18931.846740 NBT) are in the share buyback pool.
The Standard is 5.00 percent of this, -2.1441 BTC (~ -946.59 NBT)

There will be no NSR buy or sell next week.

Auxiliary reserve flow is 0.666667
PPC Standard is -3569.864304 NBT
-1500 < standard < 1500: There will be no PPC reserve buy or sell next week.

Here, this is where you’re going wrong. I probably phrased the math wrong in the motion (which is probably why I made a mistake), but the words are on point. Take the standard, multiply it by the flow, and compare it to the threshold.

For last week:
PPCST = F*ST = -$1,556.87
Since PPCST < -$1,000 sell an amount of PPC worth the magnitude of PPCST ($1,556.87) using some acknowledged price feed.

For this week:
There are issues here.

You shouldn’t add the $30k from the stable reserve here, or the PPC value either, just the BTC reserves. This will drastically reduce the standard.

131.743468 BTC stand in the core reserves.
Valued at 441.495 USD, this is equivalent to 58,164.08 US-NBT.
As 107095.93 US-NBT are targeted, we stand at a 48931.85 US-NBT deficit. This is equivalent to ~2446.59 US-NBT below standard.

ST = -$2446.59
F x ST = -$1631.06
Sell $1631.06 PPC

Please fix any mistake and ambiguity in the standard and core motion. I don;t feel comfortable following fixes in follow-up of follow-up posts. I suggest using strike through instead of deleting when editing. No need to revote. I often have a hard time parsing what you say so please make sure the math shown is correct, or interpreting and maintaining of the calculator would be difficult. Nothing personal here. For example didn’t you say

then why the quoted expression at the top of the post wrong?

Here

I think I will follow the motion

The current implementation is based on formulae in Supply, Reserves, and Equilibrium please use/revise based on it.

The motion says 2 contradicting things. What you’re following is the equations. What I’m following is the written word (which literally says ‘times’ instead of ‘divided by’). Anyway, here’s a revised version. As you can see, the only things that change are the equations, which were meant just as an addendum to help clarify anyway.

Sorry to ask a fundamental question.
I still do not quite understand the role of the Standard.
Right now, our reserves are only 12.4% of the outstanding nubits.
So we are way below the minimum 15% threshold.
Why the standard is 5% and not 100%?
Why not 1%? or 50%?
What does this parameter represent?

These three numbers define the behavior of a reserve. The target is the 15%, which you seem to be alright with. The threshold is $2500 which is more practical than anything. The 5% is a velocity. It is a flexible parameter that says how quickly we act on our debt. We used to do it with 10%, but that affected the NSR price very drastically and was somewhat unwise in my opinion. 5% is much safer. Feel free to debate or argue for another number, but I really think it’s better if we just pick something reasonable and go with it for a little while.

I’m sorry, here I meant (F x ST) = -$1631.06

PPCST is not positive, so has no effect. It only has meaning for PPC overflow calculations. That said, it is:
PPCST = PPCV x (T4PPC - PPCTR x ON) = 0.1 x (0 - 0.05 x 713972.86) = -$3,569.86
Which is precisely what @mhps got.

There are two ways to sell PPC and only one way to buy it. If we have a lot of BTC, but PPC. If we have either a small amount of BTC or a large amount of PPC, sell PPC.

The threshold being the amount that if crossed would trigger NSR sales?

How do u get this figure?
I get 570 0000 NBT
=1318251 (total supply)-151500-150000-54452-218325-173929 (uncirculating NuBits) .

So we are close to crossing the threshold.

We are extremely close to needing to do a small nsr auction, yes. If we do need to do this, i would prefer to see FLOT attempt to do it as a blind auction.
