Bitcoin / Bitcoin Discussion / Re: Bitcoin address linked to Bitcoin genesis address
|
on: October 26, 2021, 07:49:44 PM
|
Someone generated Bitcoin addresses (all unused so far) and added (ECC) the pubkeys plus the pubkey of the genesis address 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa and got a new pubkey (1C1gQwDk2sxEaYVuMjBiuCAYaNw1JE2N3s) and all calculations are correct.
Then he/she/they signed a message. The signature is correct.
To sign the message I need the privkey that I don't have. Is it possible to get the privkey without having the privkeys of the list?
Looks like a math problem for someone who knows ECC math. I'm not that person but here is my guess: Q i = k iG so Q = Q 1 + Q 2 + ... + Q n = k 1G + k 2G + ... + k nG = (k 1 + k 2 + ... + k n)G therefore k = k 1 + k 2 + ... + k nRight? As for spelling out "UnitedArabEmirates", that's trivial with vanitygen. |

CDBC's can not really be considered as crypto currencies even though there are some similarities like the use of blockchain for example. Therefore, I think the topic can be discussed in the context of alternative currencies, but certainly not in the context of cryptocurrencies Since eNira was a new term for me, I did some research and came up with this interesting article which explains it very well. It supports my words above. https://techpoint.africa/2021/08/03/experts-enaira-cbdc/Unfortunately, that author seems to lack some understanding about how money works: Simply, CBDCs are currencies created digitally to facilitate digital transactions. All currencies are created digitally, except for the small portion made up of paper and coins. While we can already perform digital transactions with the Naira, the eNaira does not need to be backed by physical cash. The Naira is also not backed by physical cash. |

I'm curious about the differences between a "digital" currency and a non-"digital" currency. It appears to me that the digital currency is different only in that it bypasses banks -- you have an account at the central bank and the payment system is run by the central bank.

Other / Beginners & Help / Re: Effect of currency burning on Bitcoin price
|
on: October 22, 2021, 08:59:07 PM

1. Ever since Bitcoin Inception and launched in 2009 till date, has it ever experience any form of burning?Not by the protocol, but coins have been intentionally burned and accidentally lost by users. 2. Considering the bearish and bullish run of bitcoin price, does currency burning has any effect on determining bitcoin price?In theory, burning coins reduces the supply so it generally causes the price to rise. There has been no demonstration of that effect however. 3. With the use of "eater address" how effective can it be in identifying currency sent to a wrong wallet address.Except for 1111111111111111111114oLvT2 (because its pubkey hash is 0), it is unlikely that many coins have been accidentally sent to any "burn" addresses. Here is a list of the known burn addresses with the most coins: | 1CounterpartyXXXXXXXXXXXXXXXUWLpVr | 2130.83949557 | | 1ChancecoinXXXXXXXXXXXXXXXXXZELUFD | 480.19421570 | | 1111111111111111111114oLvT2 | 2.99181099 | | 1BitcoinEaterAddressDontSendf59kuE | 1.91702244 | | 1NewbiecoinXXXXXXXXXXXXXXXXDN67UA8 | 1.31817000 |
4. How can digital currency burn be carried out on a particular wallet address of a deceased person effectively without compromise. If someone has access to the deceased person's wallet or private keys, they can send the bitcoins to a burn address, but I don't know why they would. The idea of adding a consensus rule to burn (or recycle) coins that haven't been moved in a long time has been proposed many times, but its benefit is minor so I don't think it will ever happen. On a related note, people are occasionally sent small amounts in an attempt to track or identify them ( so-called "dust" attack). You can safely get rid of those coins by creating a OP_RETURN transaction for each address in Electrum using the coins to pay the transaction fee.

- Do you think that this discussion helped you in some way?
Yes. I found it interesting to see what "scientific" proofs could be attempted.
- Do you think the initial question has been answered?
Partially. There was no definitive proof, but the lack of a definitive proof does not prove that one does not exist.
- Do you think the question should be reformulated?
No need. Any possible reformulation of the question has already been discussed.
- Do you think this topic should be locked?
Yes. Everything that can be said has been said.

Bitcoin / Development & Technical Discussion / Re: Bitcoin Payment button to charge the buyer AND get a commission fee for myself
|
on: October 19, 2021, 11:03:56 PM

Hello,
I want to set up a bitcoin payment button on my marketplace website, for example via bitPay, but when a buyer buys someone's article from a seller I want the buyer to ALSO pay a fee which will be returned to my bitcoin address.
How to make this possible ?
Thanks in advance!
The problem is that the sender creates the transaction. There are protocols, such as BIP 70 mentioned by ranchigo, that describe how to make a payment, but the sender's wallet must support the protocol in order to create the proper transaction. |

There is a problem with simply providing another address like that. There is no proof that you are the same person as the one that signed with 3KN...pbc. It is possible that you have gained control of the account after the the first signed message. So, if I had to verify you, I would not accept a message signed with 17F...3EW. The better way would be to sign something like "Leaving as well a legacy address, 17FRGunjF63qhzhrc5E12hU1Y2txeUR3EW, for the sake of compatibility." with the original address to prove that the new address is acceptable to owner of the original address. |

I’m not vaccinated & I don&5 wear a mask (not compulsory now in my country). I feel fine & I’ve socialised & been out a lot of the last 18 months. This last 18 months is more about control & a great reset than any novel flu.
That's as stupid as saying that you ride a motorcycle without a helmet and that you run red lights, but you haven't died yet. You can be proud of your refusal to take a drug or wear a mask, but it is only a matter of time before you suffer the consequences of your folly. I doubt it, i’m in my late 20’s with no pre existing health conditions. I’m relatively fit & run regularly. Take a look at the stats for people getting seriously ill or dying, even under age 60, it’s a ridiculously tiny %. I have an immune system which will serve me just fine. You’re welcome to inject yourself with a trial drug though. In your previous post you stated how you're not vaccinated and don't wear a mask and still you haven't gotten sick, implying that you think that you are magically immune. Now, at least you acknowledge that you could get sick and that you are simply playing the odds. You won't be in your 20's and be relatively fit forever and covid is not going to go away, so at what point do you think you will decide that the vaccine is the better choice? Also, for those that aren't aware, masks are not for your protection. They are for the protection of the people around you. If you have covid and don't know it because your symptoms are mild, you could give it to someone else and they could die. |

Definitely HODL those shitcoins...  In 2012, I mined about 2500 FTC, then worth about $25, because it was lighter than litecoin and was going to dominate. Now after 8 years, its worth about $6. In 2013, I bought about 10 AUR for around $300, because it was going to be airdropped in Iceland, Now it's worth about $0.30. In 2014, I bought 100 XPY for about $1000 because the developer set a price floor. The developer went to prison and now it's worth about $1. Many years ago I mined a dozen different altcoins on Multipool including NVC, TRC, MOON, WDC, ... None of them are worth anything now. |

Umm. Is that sarcasm? That's Vitalik, and he's hardly a "no-coiner". On the other hand, I disagree with his conclusion based on what most users think. I think it overlooks the effects of adoption. |

Your question has two parts:
1. Will the price of a bitcoin increase due to inflation?
Yes, inflation causes the prices of everything to increase due to the decline in the value of the currency. 1 bitcoin may be worth $1 million dollars some day, but I believe that will be mostly due to inflation.
2. Will the price of a bitcoin increase due to reasons other than inflation?
Greater adoption causes the price to rise regardless of inflation because greater adoption means more overall demand for bitcoins when the supply is limited.
When discussing future prices, I think it is generally better to specify the price relative to the current value of the reference currency. Since inflation changes the price of something but not its relative value, it is better to ignore inflation (unless you are talking about inflation).
For example, I believe that the maximum price of a bitcoin is about $400,000 in today's dollars because that's what the price would be if all the money in the world is replaced by Bitcoin. Since I don't know what inflation will be like in the future, I have no idea what the nominal price of a bitcoin will be.

Alternate cryptocurrencies / Altcoin Discussion / Re: which variables make my coin unique?
|
on: October 11, 2021, 12:07:23 AM

I have a question. I am forking bitcoin to create my own altcoin. I was wondering, which variables make my coin unique? In other words, what are the factors that make a bitcoin a bitcoin and a dogecoin a dogecoin? Why can't we transfer money to each other? Because of different Genesis blocks? Ports? File names? Nodes?
Ultimately, the genesis block and the consensus rules together are what make a coin unique, but coins with different rules can share a genesis block and be unique (BTC and BCH, for example). |

Bitcoin / Bitcoin Discussion / Re: What if all the money in the world entered the cryptocurrency market?
|
on: October 10, 2021, 07:08:31 PM

if it happened that all the money in the world went into the crypto market, in my personal opinion, this would be a problem for bitcoin, because there is no more freedom, what is certain is that if it did happen, it would definitely be controlled by the rich, and those who have power, so my movement as a middle class person will find it difficult to compete with people who have power, and have wealth, I think this is a bad idea..
When Bitcoin is widely adopted, then whales will have less control over the value because they will own a much smaller portion and nobody will have control over the payment system like they do now. If all the money into the world entered the cryptocurrencies I do think that would be extremely unstable.
The value of a widely adopted bitcoin would be no less stable than any other currency. Although it's only an if situation because we know that it will never happen because there are other investment assets that will remain to be a high option for most investors.
As Bitcoin is widely adopted, its price will stabilize, and it will be no more investable than any other currency. |
