1  Bitcoin / Bitcoin Discussion / When was the bitcoin white paper first published on bitcoin dot org ? on: September 25, 2023, 03:21:54 AM
When was the bitcoin white paper first published on bitcoin dot org ?
Was it published elsewhere also?
2  Bitcoin / Development & Technical Discussion / A sha256 digest and a private key on: October 29, 2021, 11:53:59 PM
If I generate a sha256 digest from some text I get one string of letters and numbers, but if I generate a key pair using bitaddress, using the same text I get a private key.
What is the relationship between the digest and the private key?

Also I thought (and I'm probably wrong) that putting some text through the Sha256 algorithm produced a 256 character string of ones and zeroes.  If that correct. If so how do we them get the digest?

Thanks for your help in understanding this
3  Bitcoin / Development & Technical Discussion / Trying to match an address to a seed. on: October 27, 2021, 06:51:37 AM
To cut a long story short my friend lost a passphrase for a ledger wallet.
So following the advice of some helpful people here I asked them to use iancoleman.io to try the 24 word see combined with some possible passphrases and compare the addresses.
 However her address begins with a "b", and Iancolman.io doesn't seem to give addresses in that format.
Can anyone suggest a solution?
Thanks
4  Bitcoin / Development & Technical Discussion / Searching for early transactions on the blockchain on: August 22, 2021, 05:36:23 AM
What would be the easiest or best way to search the block chain for in formation about the earliest transactions?
5  Bitcoin / Hardware wallets / Ledger wallet help please on: June 06, 2021, 01:31:19 AM
So I have friend who had some bitcoin stored with a ledger wallet. They used the function where you have a dummy wallet in case someone gets access. They still have their 24 words but the real wallet copntaing the bitcoin was also behind a pin number and a password , I think.
So when they tried to access the bitcoin they only were able to access the dummy wallet. They cannot remember the password.

Will they still be able to use the seed words in another wallet with the same derivation path, even if they also used a password?
Or will they need to remember the password too?

Thanks
6  Bitcoin / Electrum / I lost my password to an electrum wallet on: November 01, 2020, 08:45:20 AM
Is there any tools to try to find it?
I am pretty sure I know the words I would have used but can't remember the combination of those words.  There are probably not too many possible combinations.
7  Bitcoin / Development & Technical Discussion / Understanding SHA256 (for dummies) on: October 24, 2020, 06:00:40 AM
So, with the SHA256 process (?) we can take any string of words and numbers and *do something* to it and we get a 256 string of ones and zeroes .Small changes to the input give an unrelated new string/key.

This can also be converted to other forms/keys (?) 

Hopefully I got that right.
My questions is....What do we do to the original set of words and numbers?    What is the process?

If t is difficult to explain, then, is there a good analogy or way to explain it?

Thanks
8  Bitcoin / Development & Technical Discussion / Cost per transaction on Bitcoin? on: October 07, 2020, 05:32:21 AM
Hi all, I am ding some research and and trying to work out the possible raw cost of a transaction on Bitcoin. I guess I would assume blocks were full. I am interested in the raw cost.
Does anyone know of any resources that could help?
Thank you

11  Bitcoin / Bitcoin Discussion / Craig Wright trying to scare people. on: July 24, 2019, 01:42:10 AM
What can we do about the Craig Wright who is again threatening to sell 821,050 bitcoin next year? This is just ridiculous as he is probably causing the bitcoin price to be weak as he spreads this story.

Not sure how to post the image.
12  Bitcoin / Development & Technical Discussion / How many people could lightning network support at the moment? on: February 11, 2019, 09:18:31 AM
How many people could lightning network support at the moment?
Assuming enough bitcoin went into the system, could it support 100M, or 1B or 5B users?

Or would we need to tweak the routing algorithms more for such numbers?
13  Bitcoin / Development & Technical Discussion / Wallet recovery service? Or electrum wallet help on: January 02, 2019, 04:10:57 AM
Hi all, some time ago I had some trouble with an electrum wallet, where I tried at add an extra word to the seed.

I am happy to pay if someone can help. There will be enough in there to make it worth while.  Smiley
14  Bitcoin / Development & Technical Discussion / Question about finding a block on: December 31, 2018, 04:45:27 AM
Not sure i understand this but would be grateful if someone could help.

This is what I understand.

1.Finding a block means guessing a number.
2.That number involves showing that the transaction involves the right keys and then ..putting it through some meth equation?  Is that right?

What I wonder is ...is the miner constantly guessing numbers based on whatever transaction he intends to add to his block?

And so the transaction variable of the guessing is constantly changing?

So the miner is moment by moment is solving for a different pool of transactions?

15  Alternate cryptocurrencies / Altcoin Discussion / Was Charlie Lee promoting Litecoin before he sold his Litecoin? on: June 22, 2018, 02:38:32 AM
Was Charlie Lee promoting Litecoin before he sold his Litecoin?

was he encouraging others to buy or even saying positive things about it? Expressing a positive opinion even? 
16  Bitcoin / Bitcoin Discussion / Who is the Mt Gox trustee selling for? on: May 12, 2018, 07:17:46 AM
Mt Gox trustee has been moving coins and very possibly selling, but on behalf of whom?

As i understand it creditors were owed $400M and this debt was paid off already.

Is he now selling for shareholders, including Karpeles?
17  Alternate cryptocurrencies / Altcoin Discussion / Coins that won't be securities? on: April 26, 2018, 10:46:18 PM
Which coins wont be regarded as securities?

Presumably BTC, BCH, XMR......DCR? .....anything that didn't raise money? 

Any platforms that didn't raise money?
18  Bitcoin / Development & Technical Discussion / Password seed words for a bitcoin wallet on: April 26, 2018, 06:20:49 AM
Is there a library of words which can be included in a 12 word seed password for a bitcoin wallet?

Would the library of words be the same for an exodus wallet? (which is a multicoin wallet)

Thanks
19  Bitcoin / Development & Technical Discussion / Will bitcoins no longer be mined after 2024? on: April 24, 2018, 07:36:41 AM
Will bitcoins no longer be mined after 2024?  (or thereabouts).

The block reward is now 12.5 BTC. On or around 2020 it will reduce to 6.25 until around 2024.

After 4 years of 6.25 block rewards are not more bitcoins mined?

There are stories that Satoshi may have one million bitcoins or more.
1. Is there any evidence?
2. Are there any addresses that are thought to possibly belong to Satoshi?

Thanks
