I started a project involving several aviation tools while doing ground school for my private pilot license. It started as a way of learning the maths, and a replacement for the E6-B computer.
It is opensource, all the computations are done on the client side,
Just to add to your excellent description, one can draw an analogy between the id_token and a VC.
But an id_token usually has an audience which is the RP, and a short expiration. A VC is issued for the user (aka holder), with long or no expiration to store in wallet.
A VC is bound to the user’s did (think pk thumbprint) and is useless without a proper presentation. A verifier does not expect just the VC but a V. Presentation signed by the user.
This is where using id_tokens as vcs will fall short. Once you give it to one verifier, you could assume is public.
The good thing about VCs is that is standard and easy to grasp. There are too many flavors though
- When auth0 act as an issuer, it issue credentials with did:web
- when auth0 act as a verifier it can verify credentials and presentations issued with: did:web, did:key, did:ethr and did:ion
- The provided demo wallet at https://wallet.verifiablecredentials.dev/ supports did:key, did:ion and did:ethr
This is possible currently with zero knowledge proofs.
There are mainly two different types one is "selective disclosure", where the verifier require some fields but it is up to the Holder to select which one to disclose.
The other one allows the Holder to create proofs about claims, like "I am over 18" without disclosing the birthday. The cryptography for this seems sound, but to be honest it is hard to grasp.
For a working example you could have a look at this:
I remember we played Price of Persia without soundcard and one day my father came to tell me he saw the game in someone’s else computer and he could listen the steps and the junp.. we got a Sound Blaster 16 for that Christmas which came in a huge box. Bigger than a laptop today
Edit: maybe it wasn’t prince of persia, I am confused now.
The definition doesn’t say anything about legal, illegal or regulated.
So, you have a different definition to most economists.
It is a market where prices are self regulated by supply and demand, without coercion. It perfectly suits for the exchange of of FIATs (or crypto) between parties.
You can call it whatever you want, anyways.
I recommend “Free to Choose” from Friedman as starting point.
“ In economics, a free market is a system in which the prices for goods and services are self-regulated by buyers and sellers negotiating in an open market without market coercions. In a free market, the laws and forces of supply and demand are free from any intervention by a government or other authority other than those interventions which are made to prohibit market coercions.”
Say the central bank of XYZ set a fixed rate of 100 $xyz per USD but it becomes illegal to buy USD and no any bank is willing to sell you USD. In a country like the United States you might hedge against inflation by buying some treasuries.. but in other places they just make it illegal to do anything else.
This automatically creates a “black market” of USD where the price is whatever the people are willing to pay, in the end the free market finds its way.
Unfortunately data is not in your side. Most countries do not have economic freedom, moreover the less the economic freedom the worse the living conditions [1].
You might think that any country controls their money supply, that’s a fact. But can Biden for example, double the monetary base with his sole signature?
People in those countries could have great aspirations, to have a fair system, a working democracy, a better government and all that… but don’t forget they also need to live in the meanwhile, while fixing all those problems.
I’m not a user of crypto currently, but I see it as a way of shifting power. Similar to what the internet did for information.
it is interesting that you referred to “black market”. If you come from a working democracy where what is “just” is close to what is “fair”, then “black market” can make you think of drugs, weapons, or these sort of ilegal things. But I want to let you know that in some countries we have to go to the black market to buy another FIAT with less inflation because it is illegal to exchange our currency even to protect our savings.
So, yeah we can call it black market but I like the term “free market”.
My point is exactly the opposite, incompetent gov are a byproduct of having too much power to control the money supply. Do you think Putin will still be in power if he couldn’t control the economy, ie if he had no money? In that case, what’s the point of the sanctions?
The cicle which I am most familiar with, goes by like this: gov destroys private enterprise and free economy thru regulations and expropriations, unemployment goes up and people gets dependent on hand outs, the remaining jobs bears all the costs. Unemployed sees gov are they gods, they will kept voting for them forever, even if they live in complete missery, it is all they have.
I can see you didn't click the link otherwise you will have read the section about that.
"They" didn't solve that problem, it is not the solution to all problems in finances. So, whats your point? Vaccines does not prevent 100% of infections, does that means that they are worthless?
Fair point, I shouldn't have mention that you can put your stable coins into a DeFi protocol because even if that's interesting is not the point of the answer.
I wanted to address that in the world of crypto there are stable assets pegged to some other FIAT if you want that.
Sorry if this becomes long but I need to explain my point of view. I live in a country that is not as authoritarian as Russia but is not a free economy like the US, people don't trust on FIAT and on banks because it had happened before that they took all our savings [1]. Even if this might seem like an isolated event, it happens every day. For example, if you work remote for a company abroad, the gov will exchange your USD on a wire transfer for the local currency and then not allow you to buy back USD. Our currency had a 60% of inflation last year.
I don't like the speculative aspect of crypto currencies, its volatility creeps me out. I wouldn't want to put my life saving on this. But I can see its value to circumvent corrupt governments and to make a free world. I do believe in humanity, the Putins are an exception and when you give people the opportunity to collaborate, most of them will choose to have a peaceful living.
Now, going back to your Turkish bonds vs DeFi. The difference is you can't buy those anonymously and at any point the gov. or exchange. They actually pay that much because no one wants to buy them, primarly because they don't trust they are going to pay that much. In a way, you can think of DeFi protocols are immutable math functions [2].
True, but I would argue that oppressive facist regimes pretty much exists because they can print their money to rip off common and working people. I am sure that if you ask russians if they are willing to give away their hard earned money to buy tanks in order to support a crazy dictator they probably will answer no.
> So what did I do? I simply told him I would never give him a raise again.
It is true that salary have been always losing purchasing power but don't forget also that employees have compulsory raises. This comes from two sources:
1. minimum wage raises
2. believe it or not, unions negotiate with the gov the raises, those are called here "paritarias".
Everything is broken here, laws favor the employees always and that's why no one wants to start a business. When you talk with small businesses this is their number one fear.
Half of the population is convinced that business and owners are the devil, and that they need to die in fire.
