Hi.

79228162514264300000000000000 (2^96) private keys can generate the exact same Bitcoin address.

Why is this not a concern?

You have a private key and a public key and optionally you could password protect your 'account' after which all transactions would require you to enter this password. This password would obviously be stored on the blockchain itself.

Is something like this possible to implement?

My only concern is how would you find the block with the data that contains the password...

NEO

What for?

• Its idea of creating a "smart economy" which will be based on Digital Assets + Digital Identity + Smart Contracts

Established Competitor:

Ethereum

Cardano

What for?

• Its development is based on a "scientific philosophy" and is being developed by academics and engineers.
• Wants to balance the needs of users with those of regulators

Sites like coinmarketcap are doing a good job listing cryptocurrencies by price, market-capitalization, and supply but unfortunately none of them provide a list of features offered by the listed cryptocurrencies. Since the time I got myself involved with cryptocurrencies, I have had to rely solely on search engines to gather such information. Unfortunately, search engines are only as good as the popularity of a given cryptocurrency. Search engines will not display hidden gems or sleeping giants. This is my attempt at solving that.

I am going to start off by listing two cryptocurrencies that are unique and not spin-offs of an existing popular cryptocurrency.

So please list your favorite cryptocurrencies which you believe are unique and mention the reasons. It doesn't matter if you even copy paste points from their official website. The cryptocurrency must be unique and not be a spin-off of an existing cryptocurrency even if it aims at solving a specific problem. And if there are a few such related cryptocurrencies, only list the most popular one by market-cap.

The purpose of this thread is to help with cryptocurrency discovery. The idea is that once all major cryptocurrencies are already listed, it will become difficult to add more. And that is when the hidden gems / sleep giants will start appearing.

So one private key can generate only one public key and that one public key can generate only one address?

Greetings BTC Forum.

I have a question regarding multi signature addresses.

For example, I have just generated a multi signature address using three public keys which requires all three signatures to release the coins. The address for this is: 3BsFPGPTCfjmFpiE3K8M29wuxvq1UjDE8T

Considering that (correct me if I am wrong) there are around 160 possible private keys that can map to one single address, my question is, is it possible that a single private key could map to this multi signature address?

In that case, I apologize for misunderstanding you. I believe someone who has good knowledge of blockchain, cryptography should analyze this project. They already have provided details on their website but it's just too technical for me to understand.

A non-technical summary of this project is as follows:


Last night I downloaded their client and successfully deployed it using a Linux virtual machine. The project itself seems definitely legitimate however just like you I wonder the validity for their claim but I don't see anyway they can prove this. But this does not mean they are a scam.

Instead of creating more and more cryptocurrencies on an almost daily basis, developers need to focus on security of addresses. If I make a significant investment in a cryptocurrency and leave it for say, 20 years, I don't want to think of the possibility of someone randomly going through private keys of addresses to come across my address which contains my hard earned money.

In another forum where I had this same discussion, I got a response saying that this wouldn't be possible and that it is "like this by design". This just isn't an acceptable answer. Tell that to the guys who wanted to go the moon.

Hello.

I am new where. I don't know much about the underlying blockchain technology so I request you to please go easy on me. And please excuse my bad English too.

I discovered cryptocurrencies around 6 months ago. But since the time I discovered them, I have had problems with the fact that all cryptocurrency addresses already exist. This has bothered me a lot because I felt if someone with the right resources could go through all addresses trying to find few with balances. I was told on other forums that the chance of this happening is astronomically impossible. I did not believe this but I remained quite. Then I came across The Large Bitcoin Collider project which in a matter of 3 months or so has already found 15 Bitcoin addresses with a balance. Of these, one had a balance of 0.54 BTC. Thats quite an amount for many!

Coming back to what was said to me, that it is astronomically impossible someone could find my private key. I agree, if you are trying to search for my private key then you have a better chance of winning the lottery. But I am not talking about someone trying to find my private key, or yours. I am talking about an effort to randomly go through as many addresses to find ones with balance.

This is not something that can be compared to cracking a bank account password. If I have a bank account with ABC Bank with account number 123456789 and password a9y3zs24u0d6K@5*<ONLhF:r{ljW^Pi(, then I would wish you all the best if you wanted to crack it. But let me repeat, I am not talking about someone targeting a specific address here.

This issue has started to make me feel unhappy with cryptocurrencies. I do not like the fact that all addresses already exist, even the ones which have zero balance and of which the blockchain knows nothing about.

So my question is, would it be possible to have a cryptocurrency where you could control both the public and the private key? Or at least the private key? For example, I would like to use the following pair:

Public Key/Address: NytHawk@some-email-host.com
Private Key/Secret: J!*02gD(twzu;P.i}{<W7vTQs4:-h3fj&~`keK>yEXA^/pom8F[b=Y6BR)q+cxZG

An sha256 hash of the two would always produce 558fa7243835071efd9827497c6e458ae93a79c103ec8973ca3498cf1ad30b4f

Thoughts? Would this be possible? It would be astronomically impossible to create something like that!

Regards.
