100% Reserve looks so secure, as long as we believe in USD $ purchase power sustainability, but many of us don’t.
Reserve scheme means moving the peg to other currency or basket of goods is practicaly impossible in case of emergency like hyper inflation crisis which may be near in the future.
Still not clear as to why it’s an obvious ponzi scheme. The point of NuBits is not to provide profit opportunity for early investors. Their sole function is to always and only equal 1 USD.
Is the existence of a fractional reserve the issue here? Does the presence of any unbacked NuBits qualify it as a ponzi? Certainly the system is vulnerable to a bank run if every holder simultaneously wants to convert back to fiat. In the early phase of implementation as we are in now, having a large liquidity reserve is very important. But as the system matures and the market gains confidence in the peg, the role of the custodians and exchanges should greatly diminish. Users will transact entirely in NuBits, secure in the belief that they can redeem their NuBits for fiat currency at an exchange if they deem it necessary. But will that be necessary? If NuBits gain wide acceptance for everyday commerce, the overwhelming majority of users will treat them as USD cash equivalent. It’s essentially the same goal that Bitcoin is moving toward (trusted currency for daily commerce), except this currency is tied to a value entity people can immediately grasp today – the USD.
In your earlier thread on the potential of a speculative attack on the Nu network, @tomjoad pointed out that NuBits are not backed by NuShares yet you continue to make this assertion. I copied this directly from the first page of the whitepaper:
“The solution is a network with two types of units which are not fungible: shares and currency. Shares represent ownership of the network and their quantity should not change to accommodate changes in the level of demand for them. If demand increases, the price should rise proportionately.”

ponzi scheme - an investment swindle in which some early investors are paid off with money put up by later ones in order to encourage more and bigger risks
http://www.merriam-webster.com/dictionary/ponzi%20scheme
The substance of the definition here is that early investors are paid off solely through money put in by later investors. As you describe above…
I had thought that implementation of nubits burning was on the agenda. If so, nsr could be used to pay off early investors in lieu of your proposed ponzi arrangement.
Burning addresses the system’s lack of long term sustainability, a problem openly acknowledged in the white paper.
Is burning still controversial? Is there a camp that favors a rigid supply of nsr?
I’m not aware of any faction within the community that has been vocal regarding an immutable supply of NSR. I expect it’s still on the table–at least, it is in my mind.
The case for burning NuBits was framed as a way to reduce supply, to create scarcity, which in theory would drive prices higher.
What was the use case, benefit, and method for for burning NuShares? And what would the mechanism to decide which NuShares to burn? NuBits could be easy – shareholders would vote for a custodian to burn them.
sorry, loose language. You don’t need to burn nsr, just nubits. For nsr, burning is a substitute for dividends. Dividends work just as well. For nubits you absolutely need burning.
To be clear you need to issue new nsr to the custodian. The custodian then sells the nsr for nubits. And burns the nubits.
If you do this, nsr become backing for nubits. In central bank language, this is called an open market operation.
As long as you issue nubits in conservative quantities and burn liberally when the price of nsr falls, a peg could be sustained indefinitely.
What a great article to read!. Thank you so much @Benjamin
I strongly support the role of burn nubits custodian, who is granted with NSR , buy and burn NBT.
I think it will be not so difficult to implement in Nu’s protocol.
one Question: 1. how to apply negative interest rate in current parking function. I think it should be compulsory, otherwise no one will park NBT to get punished by interest rate.
I agree Hong Kong Monetary Authority is someone we can learn from.

What about inflation-adjusted US dollar in future. It would be better to have investment profit on the foreign exchange reserve to cover the inflation rate.
Yes, I planned to write about the parking system later, but since you ask I’ll just cover it here.
In my view, interest rates should be universal across nubits. The parking system destabilizes nubits, serves no useful purpose, and should be abolished.
Parking creates a form of asset-liability mismatch, known as maturity mismatch or term mismatch. Term mismatch plays an important role in the collapse of fixed exchange rate regimes, e.g. the Asian Financial Crisis.
The value of assets in the nubits system are predictable in the short-term, but highly unpredictable over a longer time horizon. The debt structure of Nubits should match its asset structure.
Nubits should only issue short-term debt. The option of purchasing long-term debt by parking nubits should be taken off the table.
Since negative interest rates encourage Nubits holders to sell their Nubits for USD at parity now, they effectively allow shareholders to exercise a call option on short-term debt commitments. Prudent exercise of this call option would prevent the system from ever becoming overleveraged. The parking system allows Nubits holders to evade the call option. If a significant fraction of Nubits are parked, nushares holders could lose control of the debt to equity ratio in the system. In the face of an adverse price shock, this may lead to insolvency and a collapse of the peg.

I don’t think issuance of an inflation-adjusted currency makes sense. In order for the Nubits system to be profitable for shareholders, we need a high velocity of txns in Nubits that can be milked for txn fee income. In short, we want to attract spenders to Nubits not savers. Ideally, savers should invest in nushares as part of a diversified portfolio.
It makes much more business sense to issue a currency with a relatively high inflation rate like the Chinese Yuan. Inflation means seignorage revenue for shareholders. This is the other possible source of income besides txn fees.

Agreed. I also think another important behavior of the “savers” target demographic is the establishment of a cryptoeconomy that promotes lending. I shared my thoughts in another thread here: Inflation-Protected Asset vs. Anti-Inflation Parking

How do you see this solution improving on the current NBT-for-NSR burning proposal offered by Jordan, where burn rates are voted on by shareholders? Isn’t the final outcome essentially the same (increased NSR, decreased NBT), except with Jordan’s proposal the solution is built directly into the protocol (as opposed to trusting a custodian to burn the required amount of NBT)?

Excellent discussion. My confidence in Nu community increases as a result.

I disagree. When I deposit my money with 1-3% interest, I can’t use it at my will until I take it back.
This is meaningless, what I want is a good money which is of constant buy power and ready for spend at any time. Who gives “ Federal Reserve” the power to dilute my money? I get my salary because my hard work in the past, my work was worthy of a certain buying power, if I just hoard my money, its value should neither increase nor decrease. I do nothing, so nothing should happen to my money, why should I get punished when I do nothing?

By universal do you mean fixed? If so, then this creates the Impossible Trilemma that prevents a currency from simultaneously achieving a peg to a second currency (in this case the USD), free capital flow, and fixed interest rates (monetary policy). The Nu network must have the ability to dynamically adjust parking rates in response to changing external conditions. Far from serving no useful purpose, parking is essential for Nubits’ survival.

I interpreted the comment to mean that park rates would still exist, but the same yield would exist across all durations.
If that is the suggestion I’ll need to ruminate on it; I’m not an economist, so I’m very open to the positives that this structure may offer, but that doesn’t (subjectively) feel “right”.
I mean that you never want people to commit to keep money just sitting in nubits. It is costly to back nubits and the space should be reserved for users that are actively doing txns and generating txn fee revenue. Parking incentivizes people to do the exact opposite of what shareholders would like them to.
The reason this seems counterintuitive is because it is atypical. Normally a business investment may take years to generate a return, so the business knows it will have money 5 years from now, but is much less certain of its revenue next year. The business is willing to pay a premium to borrow for five years without having to worry about the creditor calling in the money.
Nubits is the opposite case. The system’s ability to repay USD tomorrow is relatively certain, but extremely unpredictable one year down the road. A comparable example is a business that wants an option to call in a bond before it matures. Say that your investment prospects have declined relative to prior expectations, but you promised to borrow for term of five years paying interest each year. You would like to be able to repay the bond early rather than just sit on cash and pay interest. You can do this if the bond has a call option allowing for early repayment.
Negative interest rates operate like a call option as well. You can say, hey nubits depositor I’m not sure if I will still be able to repay you next year, so I’d prefer to pay you back now. The nubits depositor could refuse. However, if we have negative interest rates we can say, either I pay you back $1 now or $0.90 next year, your choice. Essentially you can compel people to take leverage out of the system and prevent unsustainable accumulation of debt.

Negative interest rates, or demurrage, are not currently enforceable by the network. Users would simply abstain from parking at a negative rate in order to avoid the penalty.
Freicoin implemented something like this, but it has not been a roaring success.

To sustain a peg in all possible market conditions you need interest rates to vary freely. Freicoin implements negative interest rates at a uniform rate. This is not the same thing at all.
Negative interest rates are only applied in extreme boom scenarios when nubits are too popular. This would almost certainly be a transient scenario. Think bubble collapse leading to flight from the other cryptos. We cannot accommodate all that money coming in at once without assuming excessive risk when it tries to leave.
Negative interest rates are used to pop the bubble before it becomes a threat.
The alternative to transient negative interest rates is to either
a) issue more nubits than the system can sustain, allowing the bubble to inflate, and risking a break in the peg when the excess inflows try to leave the system.
b) let nubits appreciate and break the peg right away

Surely the discussed burn mechanism has the same overall effect as a negative park rate?
Similar to @Ben, I am not an economist but I am reading this discourse with interest and trying to understand.
It seems that there are many users here who properly know these potential situations so can effectively ‘feel’ what would happen if any parameter was tweaked.
I’m not quite there yet, but hope to arrive sometime. In the meantime, please excuse occasional misunderstandings or dumb questions.
