I vote in favour of smaller block sizes because:

Bitcoin was created to be accessible to everyone. Thus, running a miner and running a node must be cheap hardware-wise. Don't underestimate the power of nodes for the Bitcoin networks. It's not just the miners. Increasing the block size will require more disk space. More disk space require more money. 20% of the world hold approximately 80% of the global wealth, so requiring more money isn't really fair after all.

That's exactly the thought I have for Monero.

I mean, the only chain I like apart from Bitcoin is Monero. I own some XMR too. I know that monero has a dynamic block size, depending on the congestion, which I also think is not the best idea.

But if you  look into Monero's average block size against Bitcoin's average block size, you will see Monero's is lower. Why? Bexause the traffic / activity in Monero is much smaller than the traffic in Bitcoin's blockchain.

I 've seen people mentioning RPi4 being loud using active cooling. That's true. I have bought this case, and the temperature is super stable at around 50 - 55 celcius. This case has no fan or active cooling, so if you combine it with an SSD, you will not even hear it working.

I think this is the BTC that he owns on behalf of El Salvador.

The amounts match. Actually, 3000+ BTC look too much for a personal portfolio, but this is not a strong argument, I know.

Καλησπέρα,

Το ελληνικό board έχει ξεφύγει. Δεν ήρθα να μας σώσω, δεν με ενδιαφέρει ιδιαίτερα.

Ωστόσο βλέπω απαράδεκτες συμπεριφορές και δηλώσεις. Βρισίδια και αναίσχυντες εκφράσεις.

Όσοι θέλουν το forum τελείως ζούγκλα, να ξέρετε ότι υπάρχουν και άνθρωποι που δεν γουστάρουν να βλέπουν τόσο χαμηλού επιπέδου posts.

Ναι, δεν είμαστε υποχρεωμένοι ούτε να σας διαβάζουμε, ούτε να απαντάμε, αλλά έφτασε ο κόμπος στο χτένι.

Η μόνη παράκληση που κάνω είναι να σεβαστείτε ανθρώπους που ΔΕΝ θέλουν να διαβάζουν ύβρεις μέρα-νύχτα.

Μην ξεχνάτε ότι προσβάλλοντας με βρισιές έναν συμφορουμίτη, χαλάτε την ποιότητα των posts για όλους όσους διαβάζουν.

Υ.Γ. Δεν είμαι σε forums πολλά χρόνια, οπότε δεν ξέρω πολλά από forums.
Υ.Γ Θα ζητήσω να βρεθούν moderators γιατί δεν πάει άλλο.

Καλησπέρα.


Κι εγω θα διαφωνήσω με την γενίκευση αυτή. Καταρχάς η νοοτροπία είναι κάτι που φτιάχνει γενικώς. Ίσως θέλει να περάσουν γενιές, αλλά η νοοτροπία αποτελεί μια δυναμική κατάσταση.

Δεν θέλω να με παρεξηγήσεις, σέβομαι τη γνώμη σου, απλώς την εκφράζεις απόλυτα και δεν ξέρω αν όντως το σκέφτεσαι τόσο έντονα ή απλώς το λες έτσι.


Ούτε αυτό είναι εξαιρετικά παράλογο. Όπως ανέφερε σωστά κάποιος παραπάνω, η ανάγκη για μια ζωή που δεν πηγαίνει "μήνα με το μήνα" είναι αυτή που οδηγεί ανθρώπους (όχι μόνο Έλληνες) στην αναζήτηση εύκολου χρήματος.

This is one of the best topics in the forum.

I am wondering if I could use it for emergency reasons.

I am thinking of following the steps below:

1. I have a wallet (let's call it "CLAIRE"), in which I have some UTXOs and I want to send them all in case something happened to me.
2. I will create a wallet using Electrum on Tails on a permanently airgapped pc. Let's call this wallet "STEVE".
    a. I will keep dual backup of the seed phrase.
    b. I will take the first address from the first (default) account of this wallet.
3. I will create and sign a transaction from CLAIRE to STEVE's address (from step 2b). I will add a locktime (let's say 10 years from now - or more).
4. I will export and save the transaction both on paper and digitally.

Now, is the tricky part.

I need to let someone know where to find the seed phrase backup & the transaction.

Thoughts - Questions:
1. I will save the backups in 2 separate places, but in each place I am thinking of leaving both the transaction and the seed phrase, since STEVE is empty and it can't be funded for 10 years.
2. How would I notify the people I want on how to find the backups without exposing the backups to danger?
3. Would you also leave instructions on how to find CLAIRE's seed phrase? It is kind of dangerous, considering that this wallet is already funded.

Are there still people trying to brute-force keys? I am amazed...

I edited my post above and explained you have already mentioned it. I didn't carefully read your post, sorry.


Ok, but OP can also import the file from LoyceV's website to an excel or something else and do the process manually. Excel would crash, now that I think about it.

In fact, OP wants something that can't be done with just one click.

Another solution to the problem:

Look into LoyceV's datasets: https://bitcointalk.org/index.php?topic=5254914.0

1. Download the daily data from there (it includes every address that has a balance).
2. Import them in a DB
3. Set your code to ask the DB if it includes the address you want. This will be much faster.

Optional tip: If you import batch addresses from the DB into a hashmap then you can check if it contains the address ULTRA FAST.



EDIT: It has already been mentioned by Yamane_Keto & albert0bsd above.

Do you have any examples I could look into? Perhaps a mempool.space link with such a transaction?

There is not an ideal UTXO size after all. You need variety so you can use it wisely.

This is more difficult when you want privacy. The main issue is that Coinjoin implementations normally split UTXOs in standard UTXO sizes. For example in whirlpool the main pools are 100k sats and 1m sats. That said, if you put 750k sats, you must split it in 7 UTXOs of 100k sats and 50k sats for badbank.

Therefore you are kind of obligated to use specific UTXO sizes. At least, to my knowledge... If you have any suggestions on other tools and implementations I am glad to listen to them.

Safe as in it can be easily lost / forgotten / compromised, or safe as in "not very volatile" ?


The only issue I see with this is that remittance costs are decided and applied by companies & governments, so they can easily be manipulated if they see that they lose from Bitcoin in market share.


I am glad to hear that. I don't know if Bitcoin is an asset with a complete package. What I do know, is that it's not governed by anyone. And this must be very well appreciated. There are flaws in Bitcoin, but personally I believe it is the best technological invention I have ever witnessed, alongside the Internet.

Brilliant, thanks! I really like how deep this link goes, but I need to study it further to understand it. Gonna need some time.

What do you mean "plus or minus input" ?

For 1 input and 2 outputs for segwit 0, the result should be 1*68 + 2*31 + 10 = 140 vB. Am I wrong?

I appreciate that you also provided me with a formula to calculate fees, even if it seems trivial! Cheers!

Thanks mate. Very helpful information.

---

So, having seen all that, I assume:

1. It is always better (but of course rarely possible) to spend a whole UTXO, since it is the only way to have 1 and not 2+ outputs. Correct?
2. The amount of sats doesn't count at all, as it is always represented by 8 bytes of information in the output. Correct? I kinda knew that bit already, but I ask for clarification.

Finally,

Can you give 2-3 tips to follow if I wanted to create better transactions in terms of weight? Take for granted that I use coin-control by default, so I always choose the UTXOs I spend. What I want is a way to treat them more wisely.

Problem: I have really been struggling with understanding how the transaction size is calculated.

Question: I will post my thoughts below. I will ask my questions with red color.

The best answer: Every answer is much appreciated. However, I would be very happy if one could also point an example, either from a real transaction or not.

A bitcoin transaction takes N inputs and produces X outputs.

The transaction includes the following parts:

Version	4 bytes
# of Inputs	(How many bytes is this ?)
Inputs	Each input's size (*)
# of Outputs	(How many bytes is this ?)
Outputs	Each output's size (**)
Locktime	4 Bytes

* Each input consists of the following fields:

TXID	32 bytes
VOUT	4 bytes
ScriptSig Size	(How many bytes is this ?)
ScriptSig	(How many bytes is this ?)
Sequence	4 Bytes

** Each output consists of the following fields:

Value	8 bytes
ScriptPubKey Size	(How many bytes is this ?)
ScriptPubKey	(How many bytes is this ?)

Sounds like a good choice for a country to have open mind.


Ok, but I see Bitcoin as a new payments standard and not as an investment. Of course I appreciate the market going up, but I hope to see Bitcoin becoming a huge payments network.

That's a great thing about Bitoin. Isn't it? It can be used both as an investment and a payment method. I mean with FIAT you can pay, but because of inflation you can't just hold and wait for it to appreciate, since it will drop in value as time passes.

Thanks for the info. Looks like Bitcoin wins in all categories (fees, limits etc).

Isn't it too expensive? Also, since I don't know the application, is it a flat fee or a percentage of the total transacted value?

Can it? This is my point... I am afraid not many people use it.
