Time based currency is the future! It's wrong that each person values their time differently and that's the reason why we have so much disparity in income nowadays! 80% of the wealth is controlled by 10% of the millionaires and billionaires and the rest is just getting dipped into debt! I am not a millionaire but my house costs 4 million in my local currency. TO buy this house, I had taken a loan from a bank and I am paying 35 grand every month to the bank as EMI! I also put in exactly same hours everyday in my office like any other person. Is my time valued enough?? NO!!

To end this kind of disparity, time based currency is the future and blockchain can really help us to bring the transparency in the entire system! Certainly we don't have any such system to keep track of time of an individual but we can't say that there won't be anything in future! Disparity should end at any cost!

An hour of a doctor's time is worth more than an hour of a janitor's time. Wouldn't you agree?

A person with a backhoe is faster than a person with a shovel. Why would a person ever invest in a backhoe if it means she gets paid less?

If you pay a carpenter one hour for her time, how does the carpenter pay her assistant?

Disparity is inevitable. Envy and jealousy are what should end at any cost.

I'm a random idiot on the internet, I could be wrong or lying. How do you know that 1 minute = 1 nautical mile applies to the 32 minute apparent diameter of the sun?

I know that in the case of the sun it does but how do you know? Just because I said so is not a valid reason. My point is you need measure the distance to the sun first, then you have a distance to calculate its actual diameter with.

I don't know these things and I can't measure the distance to the sun or its height or its width. You didn't measure these things either, so you must have figured them out somehow, or somebody must have showed you the reasoning or the evidence or the measurements. All I'm asking is that you share this information so that I can understand how you have come to your conclusions. Saying that I can't use simple trigonometry because you might be lying isn't helpful at all.

Sure you can. It is simple trigonometry. Given the either the distance or the size, it is easy to compute the other.

You don't know either the actual size or the distance! ...

In your diagram you label the sun's diameter as 32 nautical miles (nm) how do you know this? How do you know that the 1 nautical mile per 1 minute applies to the 32 minuets you measured the sun at?

You have said many times that the sun is 32 nm wide because it is 32 minutes wide and 1 minute is 1 nm. I'm using your numbers. Now you say it isn't 32 nm wide?

... Hold a dime at arms length and it's size is 32 minuets wide, does that mean it's 3,000 miles away? Fuck no! ...

A dime is 18 mm wide, so if it is 32 minutes wide, it is 0.018 / 2 / tan(0.533 / 2) = 1.9 meters away.

There is no reason why a blockchain couldn't be used. It's not a new idea.

https://www.ccn.com/chronobank-brings-time-based-cryptocurrency-to-change-the-labor-recruitment-industry/

My opinion is that time-based money doesn't work, mostly because each person values their time differently, but also because there is no way to ensure that a person is paid for their time instead of for the value of their work.

The OP asked about NANO computing, not quantum computing.

Nanocomputer refers to a computer smaller than the microcomputer, which is smaller than the minicomputer. ... The term nanocomputer is increasingly used to refer to general computing devices of size comparable to a credit card.

Nano computers will enable us to put a bitcoin node on a card or on a USB stick.
2406  Bitcoin / Bitcoin Discussion / Re: Ready to sue the miners? on: June 26, 2019, 01:50:30 AM
Basically because of miner's fees. Transacting in Bitcoin wasn't profitable, because miners got together and raised their fees so high that it wasn't worth trading Bitcoin.

Miners don't set the fees. A miner will include the most profitable transactions in a block, and a user will pay a higher fee so that their transactions are mined sooner.

Keep in mind that I'm combining angles from both physical space and optical space and the diagram is less than clear in this regard. R & T also need to be moved over to the left side.
First point, the distance to the sun can't be calculated from the sun's apparent size alone. As you can see I didn't use "I" or "U" at all in my calculation at all, only "Q" and "A".
You can if you know the effect of refraction. Do you know how to compute that?
...
Finally the sun is always 32 minutes wide due to refraction and maintains the same diameter as if it was at 90° because of it. As you can see the calculations for the angular size (X) have not been completed yet. In the case of the sun and moon here X will equal U and refraction plays a role such that a refracted optical space is created in addition to the physical and optical spaces.
I see. The sun appears to have the same size because of refraction. That raises a question for me. Why are the sun and moon affected by refraction in this way, but other objects are not?

No, no, no and no! You can not calculate the distance to the sun or moon from just apparent size you have to have another object, in this case I used the horizon. Atmospheric refraction is not another object.

Refraction can be determined by calculating the sun or moon's apparent size and position then comparing them with measured values. The difference will be the effect of refraction.

The sun and moon are affected by atmospheric refraction because there are layers of different density gases below them and they causes the light to change direction.

Sure you can. It is simple trigonometry. Given the either the distance or the size, it is easy to compute the other.

There is an inconsistency. If Q is 59.73 degrees and E is 1.99 nm and the angle marked 90 degrees is 90 degrees, then Z can't be 3068 nm.

Z = E x tan Q = 1.99 x 1.73 = 3.4 nm


I think you are making it overly complex. If the apparent size of the sun is 32 minutes and it is 32 nm wide, then the distance to the sun can be calculated with this:

distance = width / 2 / tan(angle / 2) = 32 / 2 / tan(0.533 / 2) = 3438 nm


Now that you know the distance to the sun, you can calculate its height:

height = distance * sin(Q) = 3438 * sin(59.73) = 2969 nm

There is a problem. If the sun is always 32 nm wide, then it must always be 3438 nm away, and if it is always 3438 nm then its height changes as Q changes. In other words, all three - width, height, and distance, cannot be constant.

@odolvlobo,
   I'll do up a diagram for measuring the Sun and Moon (this may take me a while), the 3100 mile distance calc was not done by me so I'll do it and see what I get. BTW don't confuse angle U and angle X, only with angle X does 1 minute = 1 nautical mile.

My math was wrong, so I deleted the post.

2413  Bitcoin / Bitcoin Discussion / Re: Is it possible to write a Bitcoin Public Key Generator software? on: June 23, 2019, 06:54:11 PM
TLDR:

An address is not a public key.
An address is not a wallet.
A seed is not a passphrase (though they should both be kept secret).
A seed is not a private key (though they should both be kept secret).

Let's go over the terms in order to reduce any confusion:

  • Address: This is what bitcoins are "sent" to. It is not a public key or a wallet. It is derived from a public key. It is public. If you want someone to send you bitcoins, you give them an address controlled by your wallet. Anyone can see the bitcoins held at any address. People also sometimes call it a "public address", but there are no private addresses, so "public" is unnecessary.
  • Public Key: This is used to validate a transaction. It is derived from a private key. It is frequently confused with address. An address is derived from its public key. Users generally never see public keys.
  • Private Key: This is used to sign a transaction. It can be thought of as the password for an address. If you want to use bitcoins at an address, you must have the private key for that address.
  • Wallet: A wallet holds and manages private keys (and the addresses associated with them). It is frequently confused with address.
  • Seed: A wallet uses a seed to generate private keys (and the addresses associated with them). A seed is generally represented as a string of 12, 18, or 24 words. It is not a passphrase or a private key. The seed used by some wallets may include an extra word for additional security.
  • Passphrase: A passphrase is used to encrypt a wallet or a seed. It is not a seed.

There is no way the price of a BTC could reach $10 million (in today's dollars). Even if you replaced all of the gold in the world and all of the money in the world with BTC, a BTC still would be worth less than $10 million.

It's market cap so it is possible. It would be astonishingly silly but not a 100% no no. This is why I wish we had something better than market cap but no one's come up with anything yet.

I agree that speculation could drive the price to any value, temporarily, but I stick to the fundamentals because I don't like to gamble.
2415  Bitcoin / Bitcoin Discussion / Re: [VIDEO] 10 Million Dollar Bitcoin End Game on: June 23, 2019, 05:46:16 PM
There is no way that the price of a bitcoin could reach $10 million (in today's dollars).

Even if you replaced all of the gold in the world ($8 trillion) and all of the money in the world ($18 trillion) with Bitcoin, a bitcoin would be worth only $1.24 million, which is still much less than $10 million.

I think $140,000 is doable. That is the equivalent of replacing the USD with BTC. Even though replacing USD is extremely unlikely to ever happen, people holding BTC as savings will boost the price somewhat.

Some people (notably the Winklevii) predict $350,000, which is equivalent to replacing all the gold in the world with BTC. Again, that is unlikely to happen, but BTC is better than gold (assuming that it succeeds as a currency), so it could replace gold to some extent.

Some people say $1 million. I think that is just wishful thinking.

I see. The issue then is that you have drawn the line to the horizon incorrectly because it is parallel to the ground and should never intersect it. If it is parallel, then the angles are 90° and P, E, and C are correct.
Next, why do you divide A by 90 when computing O? I don't understand that equation.

The distance to the horizon A is divided into 90° because there are 90° between the observer and the horizon vanishing point at 0°.

90°? Where does that come from?

I created this to show how to measure the angular size of objects. If you see any errors let me know.

https://i.imgur.com/zS0G3hs.jpg

The angles that you have marked as 90° are not 90°. As a result, the calculations for P, E, and C are not correct.

P, E and C are not calculated from the diagram markings, they are calculated using measured and known values thus they are correct.

The marked angles can't be drawn at 90° due to optical convergence, hence the 90° angle notation to indicate their actual values. The reason for this is that parallel lines optically converge to a point at the horizon (see photograph with angle marked in red) but, physically parallel lines never converge. The 90° angle can be confirmed empirically by observing that the horizon line is at eye level.

I see. The issue then is that you have drawn the line to the horizon incorrectly because it is parallel to the ground and should never intersect it. If it is parallel, then the angles are 90° and P, E, and C are correct.

2418  Bitcoin / Development & Technical Discussion / Re: Best/easiest way to generate a private key with XX sided dice. 16? 60? on: June 22, 2019, 05:57:50 AM
I've been thinking about grabbing some 16 sided dice, rolling them 64 times, converting the rolls to hex then punching that into bitaddress.org or segwitaddress.org.

I was trying to think of a way to avoid that step and was looking at 58 and 60 sided dice. Of course 58 sided dice aren't fair (different shapes/sizes) so I wouldn't go with that, but 60 may be an option. I could just reroll if I rolled a 59 or 60.

This leaves me with one issue. Is that even going to help me generate a private key? It would have to go through some checks so it's in the right format, so would it be worth buying such a random die, or would getting hex dice and converting that make more sense?

Side note, is it "more random" to flip a coin 256x, roll a 6-sided die 99x or roll a 16-sided die 64x? If you know of where I can read up on probability/entropy please let me know. I'd rather learn it for myself so I really understand it. Any other simple/quick entropy sources would be welcomed as well. I'm just trying to save myself some time when generating private keys for cold storage and I don't trust other entropy sources since idk where they get it from or how it works. Thanks!

You can't randomly generate a base-58 WIF private key directly because some of the bits contain non-random data. So you are going to have to generate a random 256-bit value and convert the result to a private key. Also, keep in mind that not all 256-bit values are valid private keys.

Basically, the number of N-sided dice you must roll to get 256 bits of entropy is 177.446 / ln N.

2420  Economy / Economics / Re: Bitcoin gini coefficient is increasing on: June 21, 2019, 03:02:03 PM
Addresses are not people, and they are not correlated. The biggest addresses belong to custodians who hold bitcoins for millions of people.

As a result, the GINI coefficient is not a measurement of wealth distribution, but is actually a measurement of the preference to hold bitcoins in custodial accounts.

Ironically, that still means that a high GINI coefficient is truly a bad news for Bitcoin, but for a different reason.
