4601  Bitcoin / Development & Technical Discussion / Re: What is the earliest block to contain transaction fees? on: May 06, 2022, 05:24:41 PM
In Genesis and about a year later it seems that there were no transaction fees, only the block reward (50 BTC at that time).
Block 2817 (Feb 3, 2009) was the first one to contain three transactions, two of which paid a fee of 1 BTC. Generally, though, people didn't have to pay anything back in 2009. Blocks were nearly empty, and I think satoshi had set the size limit to 32MB. The next one is over 10,000 blocks later.

That's a historical thread regarding this matter: https://bitcointalk.org/index.php?topic=48

What made some transaction have fees and others not have fees at that time?
From the link above:
There's a small transaction fee for very large transactions.  The node that generates the block that contains the transaction gets the fee.

If the same money gets sent again, it won't incur the fee again.  If all you have is generated coins in your wallet, if you send them all in one huge transaction, it has to bundle hundreds of 50 bc coins together.  After that it's just one line to send the combined unit.

My try: Drawing patterns and lines that help deciding for trading options based on probabilities.
But, are there actually patterns? Is it, indeed, a matter of probabilities?

Or, formulated more properly: Can you prove that it's a matter of probabilities?

4604  Other / Archival / Re: Announcing Wasabi Wallet 2.0 on: May 06, 2022, 01:28:54 PM
But from a practical standpoint, for a person who merely wants to mix his/her coins without the risk of the "taint", I believe the trade-offs accepted to use Wasabi, if he/she truly wants to use CoinJoin, is OK. Less risk.
There's no point to continue the discussion, we're just repeating ourselves. We've covered that those who'll use Wasabi to gain privacy, won't, because zkSNACKs is now cooperating with those who'll hand over this sensitive info back to the centralized exchanges. If they want to have their activities private, perhaps they should begin by canceling their Coinbase account first?

So you may buy password protected wallet and try your luck or you may just get one for free.
That's right. As I've already said, it doesn't make much sense to share so much money with strangers. Perhaps because it's not yours either.
4606  Bitcoin / Development & Technical Discussion / Re: Bitcoin Core wallet.dat file containing 3.5 BTC + Password Hint on: May 06, 2022, 12:37:51 PM
For that amount, I suspect the hints aren't proper, for if they did, one would have cracked the password already. OP, are you sure the password is 4-8 characters long with the English letters and/or numbers? Is there a slight chance you've chosen a special character which isn't mentioned?

For those who say it's a scam, what's the benefit of the scammer exactly?
4607  Bitcoin / Bitcoin Discussion / Re: Ledger USB problem in the airport on: May 06, 2022, 12:07:27 PM
When entering any country, there are restrictions on the import of funds.
But, there are no funds imported, that's what I'm saying. Moving the wallet across the world doesn't move the funds. It's the key, the authorities have no access to, that is used to transact. Besides, hardware wallets aren't the only bitcoin wallets. Should they check my computer and mobile phone too? It's a nonsense.

The receiving party, if its representatives at the airport understand the purpose of ledger or other hardware, are simply obliged to check the balance of the device.
If they understand the purpose of the hardware wallet, they should also comprehend that there's no point into doing that. My balance can be faked. I can empty it right before I enter the airport, send it to one of my addresses whose keys aren't contained into the hardware, show them I own no coins, and recover them once I reach my destination.

There's a non-zero chance that this could end in a $5 wrench attack-like situation, but far worse because it's actually the authorities who's trying to access your funds, not some urban crackhead.
What's up with their intentions? Do they want to rip me off? If yes, then yeah, it doesn't matter. Still, they need my permission to rip me off. But, I don't think that has to do anything with the discussion.

blackhatcoiner is not correct
I don't understand. Where am I incorrect? You've just described in a detailing how a mnemonic works.

Do you know exactly how to input a seed phrase into vanity gen?
No. And I just did a search, nothing came up. It's trivial to write, but no, I can't find any github repository, which seems weird. One should have made this. If you really need it and you can neither find anything in the internet, pay someone to do it for you. You can find people for this very job in this sub-board.
4609  Bitcoin / Bitcoin Discussion / Re: Bitcoin Seed Phrases and Vanity Adresses on: May 05, 2022, 05:11:15 PM
1. My understanding is that the Bitcoin adresses are created randomly from the seed phrase and there is an unlimited amount basically possible.
Bitcoin addresses are derived from your randomly generated seed.

2. Is it possible to create a vanity adress from my seed phrase or extract the seed phrase from a vanity adress?
The former is possible. Just take a seed phrase and start brute forcing your prefix in derivation paths until you find such address. An extended key can generate up to 2,147,483,648 children. You could just change the seed if you've tried them all and restart. The latter isn't possible because hash functions are irreversible and what you're saying here is to recover the preimage (the seed) of a hash, which is essentially the address.

Code:
            possible
Hash(seed) ───────────► Address

            impossible
     seed  ◄─────────── f(Address)

Or, perhaps, instead of "impossible" that sounds absolute, let's say that no one has managed to find such function f that does it.
4610  Bitcoin / Electrum / Re: Decode a signed transaction to find the private key? on: May 05, 2022, 04:30:48 PM
So there is no possibility of hacking a wallet by decoding a raw transaction.
No, that's what is contained in blocks publicly anyways. Take a random transaction and search it on a block explorer, such as mempool.space: https://mempool.space/api/tx/da526ae2f1d8b58253dc9e26810a8e76c8eb11a8ebe995e132a4b22740b38773/hex

This is how public key cryptography works. You can verify one owns the private key without knowing it.

4613  Bitcoin / Bitcoin Discussion / Re: Why node operators are not given free bitcoins for hosting blockchain ? on: May 05, 2022, 10:37:46 AM
you have the full option of privacy protected literally
Well, you never get full privacy in this world, but you somewhat enhance it by running a full node.

there are currently about 15k nodes today
These are only the reachable nodes, which means those that accept incoming connections. Luke.dashjr.org must be showing all of them; they're ~49850 currently.

This is something interesting:
31981 /bitcoinj:0.16.1/Bitcoin Wallet:9.03/ Bitcoin Wallet for Android
Most of the full nodes run 0.16.1 with bitcoinj.
4614  Bitcoin / Bitcoin Discussion / Re: Why node operators are not given free bitcoins for hosting blockchain ? on: May 05, 2022, 10:06:40 AM
I know satoshi intended for miners to get the moolah for the handwork but aren't we node operators part of the bitcoin operational community?
We are all part of it. Miners, nodes, traders, SPV server runners, centralized exchanges' CEOs, Elon Musk, me, you. There's no specific requirement to be part of the bitcoin community, other than to use bitcoin.

As time goes by there will be less node operators due to blockchain size.
This is a false conclusion. The increasing chain size isn't the only factor that affects this. As a counter argument, I say that this will not be true, because as time goes on, more people will be obsessed by the idea of being financially autonomous and that hard drives will become cheaper.

Coundn't the software be updated to reward node operators for x amount of uptime will lead to x amount to free btc?
Despite the fact that there's no effective way to do this, you make it sound as there's no reward, but there is a very significant: You get the ability to verify everything yourself, you don't have to trust anyone's words of what's the correct ledger, you follow Proof-of-work that can't be faked. You gain financially sovereignty and the truth. Also, it's much more private.
4615  Bitcoin / Bitcoin Discussion / Re: Wikipedia stops accepting btc donations - “inherently predatory” on: May 05, 2022, 08:58:26 AM
After all, it is Wikipedia and not Bitcoin that will benefit from keeping such donation option.
These news aren't irritating because Wikipedia stopped accepting bitcoin donations. I honestly couldn't care less about that; it's the way they, along with any other business these days (see Tesla), justify it to their users. We have so many counter arguments about the climate problem, which makes it a poor choice to explain your suspension of bitcoin.

Stocks are also risky investments, they endorse it too. But do they or can they accept donations in stocks?
You've gone far. How about suspending fiat donations? Much more environmentally damaging.
4616  Bitcoin / Electrum / Re: [GUIDE] How to Safely Download and Verify Electrum [Guide] on: May 05, 2022, 08:48:10 AM
I am not sure 100% that it works because I can't open the file  (.asc) but I guess it's normal because GPG is not installed yet.
Yes, you should first install GPG and then open the file with it.
4617  Bitcoin / Development & Technical Discussion / Re: Sending coins and receive "change" on special BTCAdr on: May 05, 2022, 08:47:23 AM
My question is: how could I still send from one BTCAddress (or label) to another BTCAddress
and receive the change on a specific BTCAddress (prefered my main BTCAddress for the senind person)
via cli?
Using sendmany. Example from the RPC API Reference:
bitcoin-cli sendmany "" "{\"bc1q09vm5lfy0j5reeulh4x5752q25uqqvz34hufdl\":0.01,\"bc1q02ad21edsxd23d32dfgqqsz4vv4nmtfzuklhy3\":0.02}"

The first address is your person's address, the second is the change.
4618  Bitcoin / Electrum / Re: [GUIDE] How to Safely Download and Verify Electrum [Guide] on: May 05, 2022, 08:28:31 AM
1) I am able to save it (From File>Save as ...) in .txt but not in .asc (you seem to say that it's possible to direct convert in asc. for the link but I don't see the option. Am I wrong somewhere ?
Choose Finder > Preferences > Advanced. Now you can check "Show all filename extensions." if it isn't already checked. Now go to the directory you've saved your .txt file and rename it to <any_name>.asc.

To convert a .txt fil in .asc it needs to download again a new software.
There's no need to download any software for this. It's as simple as renaming a file.
4619  Bitcoin / Electrum / Re: [GUIDE] How to Safely Download and Verify Electrum [Guide] on: May 05, 2022, 07:24:57 AM
1. Do I copy all the text ? (including "Begin PGP Public key block" etc ...) Or only the key ?
You copy all the text. Actually, you don't need to copy it at all, just save it as a .asc file.

2. I have tried with TextEdit on Mac BUT when I try to save I don't see the .asc extension.
You can save it as a .txt, if it doesn't allow you directly as .asc, but it should be trivial to change it to .asc later. In the directory you've saved it, doesn't it show you the file extensions? If not, check: https://duckduckgo.com/?q=mac+show+file+extension
4620  Bitcoin / Development & Technical Discussion / Re: Bitcoin Core wallet.dat file containing 3.5 BTC + Password Hint on: May 05, 2022, 07:15:11 AM
Hello, I got one wallet.dat containing 3.5BTC and the password is 4 to 8 digits numbers and letters only, pretty easy one.
If it's a pretty easy one, why don't you pay a wallet recovery service to do it for you? The most reputable I know is walletrecoveryservices.com. Dave, who's the administrator, takes only 15% of what's found for amounts greater than $100k.

It's already late, but if it's indeed easy, don't expect someone to send you more than a tenth of it. That's a lot of money.
