Of course it is normal. Maybe not typical or common, but certainly normal.
902  Bitcoin / Bitcoin Technical Support / Re: strange bitcoin addresses, algorithms and bruteforce on: November 29, 2021, 09:02:50 AM
1-how many addresses are there with this characteristic?

Hard to say. Less than 4933 (6.0x1055) because most of those would have an invalid checksum. More like 4927 x (49/58)6, or 1.6x1045 if you assume that the last 6 are the checksum.

1- what are the probabilities of finding this type of address?

In a random address, for each digit, the probability of being a letter is 49/58, so the probability of 33 of them being a letter is (49/58)33, or about 1 out of 261. It is not that rare.

2- If a brute force code is executed with my code, how many addresses will I find with these characteristics?

If you generate addresses at random, 1 out of 261 will have only letters.

3- as these types of addresses are considerably strange and proportionally in less quantity, does my code make them vulnerable?
Does the owner of "1LdRcdxfbSnmCYYNdeYpUnztiYzVfBEQeC" have a strangely vulnerable address? If so, and read this, I hope you move your
money to a more secure address.

No, because there is no way to generate only private keys of addresses with only letters.
903  Economy / Economics / Re: Is there any change that protect crypto from fractional reserve style stuff? on: November 22, 2021, 11:53:59 AM
Fractional reserve banking type of things can be done with fungible items. Is there any change to bitcoin (or bitcoin style crypto) that would make fractional reserve banking or something else, impossible or harder to exist?

Bitcoin's fixed supply does limit FRB compared to fiat because the risk of collapse is greater as the reserve ratio goes lower. With fiat, there is an unlimited supply of money available to prevent a collapse so the reserve ratio can be 0.
904  Bitcoin / Legal / Re: Satoshi's 1 Million Bitcoins Legal Court Case Kleiman vs Craig Wright questions on: November 22, 2021, 06:46:19 AM
If Craig Wright loses, he will have to pay Kleiman 500,000 Bitcoin or the usd value of that amount.

According to the lawsuit, this is the claim:

Quote
121. While the exact number of bitcoins remains to be determined, by Craig’s admission, Dave’s estate is entitled to the possession of at least 300,000 bitcoins. Further, Craig’s admission that Ira owned 50% of W&K entitles Dave to possession of at least 550,055.5 Bitcoin. Finally, pursuant to the formation documents of W&K, Dave is the sole member of W&K and would therefore be entitled to possession of all 1,100,111 Bitcoin mined by W&K.
...
125. Dave’s estate is entitled to actual damages, amounting in either return of all bitcoins converted from Dave’s possession or the fair market value of the bitcoin.

Hello. Please tell me how to make the simplest token on the bitcoin blockchain on laer 2?

There are protocols for implementing tokens on Bitcoin, such as Counterparty and Omni. I think those have gone out of favor with the rise of Ethereum.

4. The security of the network against 51% attack is determined by the value of the block reward. Burning a portion of the block reward would therefore lower the security. Is that acceptable?
Isn't this subjective? One may say that, economically-wisely, its deflationary properties are more significant than the security and therefore, we should burn a proportion of the block reward. Another who thinks oppositely, may support increase in the block reward making it inflationary, but increasing the security alongside.

I don't think it is subjective. The value of the block reward determines the cost of a 51% attack, which is what provides the economic security against such an attack.

Deflation is no better than inflation.
Isn't that also subjective? Doesn't it depend solely on which side of the political compass you're in?

I guess some political goals might be aided by inflation or deflation, but in my view, inflation and deflation are the same but opposite -- inflation is negative deflation and deflation is negative inflation. Both are equally disruptive by reducing the efficiency of an economy.



1. Is there any benefit to an explicitly deflationary currency beyond increasing the wealth of holders? In my view, as a unit of account its value would ideally remain constant. Deflation is no better than inflation.
I agree 100% to this.
This is "fee burn" stuff is a shitcoin mentality.  People just print billions and billions of coins, then create a mechanism to slowly burn those coins to make them more valuable,  trying to pump the value.
Bitcoi  doesn't need that. Bitocin value is in its protocol, decentralization and technology.  We don't need to burn coins to make it valuable. The stability of basic protocol rules and mining economy is more valuable than that.

If the goal is really only to enrich holders, then the proposal would transform Bitcoin into an explicit pyramid scheme. Currently, Bitcoin is kind of a pyramid scheme because of the "store of value" narratives, but I hope that it will outlive those narratives and eventually become real money.

2. Why is the burn rate variable? Is the intention to discourage a rise in the total hash rate?

3. How would the proposal effect the business of mining? A variable burn rate between 10% and 90% would make it very dificult to predict revenue.

4. The security of the network against 51% attack is determined by the value of the block reward. Burning a portion of the block reward would therefore lower the security. Is that acceptable?

2) If I buy more BTC and transfer it to my cold wallet, does it just get added to my existing amount on the cold wallet? Or does it exist as a separate amount, separate transaction?

For example on Monday I buy 1 BTC and move it to my wallet. Then on Wednesday I buy 1 more BTC and move it to my wallet. Does my wallet now say I have 2 BTC in one pile? Or does it look like I have 1 BTC + 1 BTC organized separately? Maybe this is a strange question but I don't think so, I want to know how this works before I commit further to crypto, it's scary enough as it is.

Your wallet will say that you have 2 BTC, but you really have 1 + 1 = 2 BTC. The difference is completely handled by the wallet, and it only really matters when it comes to transaction fees.

Here is the situation that some people experience regarding transaction fees:

Let's say that you have 2 BTC, but instead of being paid in one or two transactions as in your example, you are paid in 200 transactions of 0.01 BTC each. The wallet says you have 2 BTC, but you really have 0.01 + 0.01 + ... + 0.01 = 2 BTC. When you try to send that 2 BTC or (any significant portion of it) the transaction fee will be very high.

The reason is that each of the 200 transactions is an "input" to your transaction, and the fee for your transaction is roughly proportional to the number of inputs. So, if the fee to send 0.01 BTC (using only one input) is X, then the fee to send 0.02 BTC (using 2 inputs) will be 2X and the fee to send 2BTC (using 200 inputs) will be 200X.

The solution to this problem is to consolidate inputs. That is done by sending all of your BTC to yourself when the fees are very low (1 sat/vbyte). That will consolidate all of the small inputs into one single large input, so that if must send when fees are high, you only use 1 input (rather than 200). However, the potential drawback to consolidating inputs is reduced privacy.

What do you dislike about controlled low inflation? This forces people not to freeze assets, but either use them (buy goods / services), or invest ... That one thing or the other launches a very important process of "money movement" in the economy. And this is essentially a synonym for the blood flow in our body in our circulatory system. If it is slow, all processes freeze, our activity tends to 0, there is no strength, we become incapacitated. It is the same in the country's economy when money stops active circulation. And then gratitude, and inflation including

That's a pretty narrative, but I don't think any of it is correct.

My understanding is that an intentional low rate of inflation is like the tail on a kite. The shorter the tail, the more unstable the kite. But the longer the tail, the more it weighs the kite down.

Personally, I think inflation is more like opium. At low doses, it subdues a person, making them lethargic and unresponsive, but happy. At high doses, it kills the person. The real question is whether or not the opium actually helps.
911  Bitcoin / Development & Technical Discussion / Re: A Two-Round Proof of Work instead of PoW on: November 16, 2021, 06:08:57 AM
Where is the energy saving here, when the miner will have lower electricity bills, but there will be more miners?
And the statements that Bitcoin "waste" energy (and consequently imply that something needs to be done about it) haven't been debunked many times?
The energy saving comes from the fact that most of miners will spend their time on Round 1 that is not heavy-energy / CPU consuming.
At least this is the target, the bet and the hope.  
In your system, consuming more electricity in round 1 gives a miner a better chance of going to round 2. How will your system limit the amount of electricity consumed in round 1?
The complexity in Round 1 is supposed to be small. ...

Please explain how a lower complexity reduces the amount of energy used when miners are encouraged to increase energy usage in order to be one of the first N2 miners. Whether it takes 1000000 tries on average or 1018 tries on average, miners are going to use as much energy as they can in order to be first.
912  Bitcoin / Development & Technical Discussion / Re: A Two-Round Proof of Work instead of PoW on: November 16, 2021, 05:25:00 AM
What is the probability of an honest longest chain be outside the N2 List (Or we can extend it a bit to N2 List of N2 miners because each miner who succeed Round 1 is broadcasting its List. But we don't need to as we can just merge the lists and put a cap at N2)?

I don't think it is possible to have a single N2 list. Each miner that completes round 1 will have a list that may be different from every other miner's list. Furthermore, there is no way to agree on which miners were the first miners to complete round 1 because there is no way to resolve the differences in the lists.
913  Bitcoin / Development & Technical Discussion / Re: A Two-Round Proof of Work instead of PoW on: November 15, 2021, 08:35:43 PM
1- If a miner receive $N_2$ $nonce1$ or more broadcast from other miners before finding its own $nonce1$, it will broadcast the list of the first $N_2$ winners and drop the current block competition and move to the next block. In this case it failed the first round and the block reward.
2- If it finds its $nonce1$ before receiving $N_2 - 1$ solutions from other miners, it will broadcast its $nonce1$ with the list of all the miners that found the solution before it including itself. it will continue listening the network to build the full list of the first $N_2$ winners. And at the same time move to the next round competition. In this case it succeed the first round.
...

How is #1 enforced? What prevents a miner from executing #2 if it finds its own $nonce1$ after it has already received $N_2$ $nonce1$? A violation of #1 cannot be detected.

If you don't accept a block by someone not in your list, then you can't follow the actual longest chain. If you allow a block from a miner not in your list then every miner can include themselves in their own list (as soon as they complete round 1), which you must accept in order to resolve a split.
Please Read instructions 1) and 5) below.

Nothing in your miner instructions ensures that every miner has the same list of $N_2$ miners. Therefore, #5 will cause a split that cannot be resolved by the longest chain because a block by a miner not in another miner's list for that block is not considered valid by that miner.
914  Economy / Economics / Inflation is always and everywhere a monetary phenomenon -- Milton Friedman on: November 15, 2021, 07:04:21 PM
Politicians are telling us that the current level of inflation is caused by "supply chain issues". That is a lie. They are lying in order to hide the fact that rising inflation is a direct result of their policies.

The truth is what was said by the famous and highly respected economist Milton Friedman said: "Inflation is always and everywhere a monetary phenomenon." The problem is not the supply chain. The problem is that the huge influx of money into the economy from central banks and governments has fueled a tremendous surge in demand.

Companies can't find workers to fill the demand. Why not? Because the government paid everyone a bunch of money so they don't need to work. This is shown by the fact that the labor participation and unemployment rates are both low.

915  Bitcoin / Development & Technical Discussion / Re: A Two-Round Proof of Work instead of PoW on: November 15, 2021, 10:29:45 AM
The PoW job is also to maintain the Block Time at 10min. We can achieve that by just making everyone wait for that 10min minus delay/network broadcasting time etc.
Say round 1 only takes 2 minutes to get 100 miners. Then you just wait 8 minutes to select the "winner".  That's a 10 minute block time. So it saves 8 minutes of hashing. Less global warming.

You would need a way to prevent the knowledge of the winner for 8 minutes so that nobody can start on the next block before the 10 minutes have past.
916  Bitcoin / Development & Technical Discussion / Re: A Two-Round Proof of Work instead of PoW on: November 15, 2021, 09:58:03 AM
Keep in mind that in order to win a block reward, you need to be in the list of N2 miners of other miners.

The first N2 solutions received by one miner could be different from the first N2 received by another. Do you have a way to achieve consensus on who is in the list? If there are different lists, then the network will split when miners don't agree on who is in the list.

Again like in Bitcoin, we take the longest chain. No difference with Bitcoin. The honest and fastest miner will always win in the long run.

If you don't accept a block by someone not in your list, then you can't follow the actual longest chain. If you allow a block from a miner not in your list then every miner can include themselves in their own list (as soon as they complete round 1), which you must accept in order to resolve a split.
917  Bitcoin / Development & Technical Discussion / Re: A Two-Round Proof of Work instead of PoW on: November 15, 2021, 06:42:48 AM
If you use more CPU power, you have always better chance to advance to Round 2.

So then, why would miners use less power?

You state "In the first round, we run a similar Bitcoin PoW..." If the first round is similar to Bitcoin PoW, then it has the same economic incentives, in which the cost of mining is limited only by the value of the block reward, regardless of the complexity. It seems to me (I may be wrong) that you may be succumbing to a fallacy similar to the belief that more efficient miners (in terms of J/hash) in the future will cause the overall power consumption of mining to fall.
918  Bitcoin / Development & Technical Discussion / Re: A Two-Round Proof of Work instead of PoW on: November 15, 2021, 05:36:34 AM
The electricity will be reduced by the fact that Round 1 is not computing-intensive

Regardless of the complexity, if I use more power to increase my hash rate, then I will have a better chance of getting to the second round. Right? So, why wouldn't I use as much power as I can to get into the second round?

I think a solution would be to eliminate the PoW in the second round and simply make it a random selection (somehow). That would cut the expected block reward by a factor of N2, which would cut the power usage in the first round by that same factor.

So basically I was doing this online quiz and they kinda like “rank” you based on your correct rate. I wanted to score the highest but kept failing, I was wondering which question I answered wrong, and I thought it was this one.

Which one?
920  Bitcoin / Development & Technical Discussion / Re: A Two-Round Proof of Work instead of PoW on: November 15, 2021, 04:33:59 AM
You don't explain how your system reduces the energy consumption. Miners are going to expend as much energy as they can afford in order to be included in the second round. Right?


Quote
... and the fastest N2 miners that solved the first round puzzle advance to a second round where they get to choose between them the fastest miner to solve its ounce2.

It may not be important, but how are the "fastest" miners chosen? In Bitcoin, the first block produced is not necessarily the one ultimately added to the chain. In your system, each miner can have a different set of first N2 blocks. Also, just to complicate matters, as I stated before, there is no reason for a miner not to submit their block as one of the "first" N2 blocks, even if they have already seen N2 blocks.


BTW, the word is "nonce", and not "ounce".
