Actually, any investor-based game can be considered a ponzi, which is a scam, because:

• There are promised returns from the creators.
• The investments are unregistered by unlicensed sellers.
• There's no legitimate activity which will be the main source of profit for the investors.

The forum itself allows you to create pyramids; it just renamed it to investor-based games.

PGP stands for Pretty Good Privacy and it's an encryption program. It is used for signing, verifying, encrypting, decrypting e-mails, files or whole disk partitions. An open standard of PGP encryption is OpenPGP.

GPG stands for GNU Privacy Guard and it's an open-source software that replaces the PGP's cryptographic suite. It is part of the OpenPGP and uses a combination of conventional symmetric-key cryptography for speed and public key cryptography for ease of the keys' exchange.

For identification. You'll upload your fingerprint to a server along with your public key and if someone ever wants to search you, they'll just use the fingerprint to claim the whole public key.

A key ID and a fingerprint is the same thing. I can't think of another thing you can share in PGP if we exclude encrypted/signed messages.

It depends on your character. If you're a person who wants to “dig” the technical stuff and understand how they work, then you'll have to deal with the maths behind the symmetric-key cryptography used in PGP.

Why don't you leave an article that explains it provably?

Beware of the articles especially when their topic is about cryptocurrencies. They may bring confusion. I don't fault them, though; learning about Bitcoin or any other cryptocurrency at a technical level isn't easy. It is required from you to ask questions whenever you feel you have to.

For Bitcoin, study from reliable sources such as bitcoin.it, bitcoin.stackexchange.com, learnmeabitcoin.com. I personally consider this forum great if you're newbie and thirsty to learn.

And how will you distinguish the ones that're frauds? If the mods didn't decide to delete some of them, it's probably because the header seems enough.


I haven't tried reporting something that makes a splash, but I guess even if I did, it wouldn't be accurate due to this header.

Good point.

The board is consisted of newbies who try to make us rich, so that's the title I'd give to Investor-based games. In the unofficial list, it is put like this:

So I'd say bitcointalk is asking for it!

I've probably misunderstood what you said, but:  If you don't keep the spent transaction outputs, but rather dump them later instead, how will you maintain the chain? The PoW was done with these included.

Actually, quite the opposite. Everyone's stealing the coins as they become slightly richer due to this feature. They become richer due to the user's inability to spend their funds.

I think that you should think of Bitcoin as cash; it has been told hundreds of times. What would happen if you left your cash or gold buried in the ground for over two decades? Would you be unable of spending them?

I think that you're trying to find a solution to a problem (Satoshi's rewarded addresses whose public key is exposed) and you introduce others by doing so. Of course, consensus is required to enable this. What I'm telling you is that the users will never come in an agreement for it due to its utopianism.

And how's that a better analogy? What will you do once you run out of money in your bank account? Won't you deposit? Fiat & Bitcoin are the currencies; bank & LN are related, leave visa out. It looks more like the comfort provided by the blue wallet's LN implementation which works custodially.

The LN is more like a trustless bank. You still need a third party, but that happens non-custodially.

I wasn't planning to use this as an argument.

For each person? It's practically impossible. I'd rather see a smarter way of paying lightning-ly; maybe having one channel for each family or by using a fully custodial service. Yeah, I said it. If they don't care about that, which they mostly don't, we aren't going to force them be responsible for their own money.

But, someone who demands it should have that right, agreed?

The lightning network is, essentially, a time deposit. If you're left with some cents in your bank account, you'll have to deposit, which takes time. Same thing happens here; you deposit bitcoins onto your lightning “account”. So, I'd say that unless you find the bank deposit funny, the need to increase your funds in LN isn't funny.

It isn't a pattern. If the transaction that takes at least 40 minutes to get confirmed is less profitable to be included into a block compared with the other 3-4, then they'll obviously be confirmed sooner.

Have you studied how things work in cryptography? Or just in Bitcoin? You've registered recently and you keep trying to find a way to cheat the system. Cheating the system isn't as easy as it seems. It's way harder than you thing and infeasible if each user was cautious enough.

This isn't a nice wording. First off, you'll have to define us what you mean by saying “infinity”. Infinite different keys? If yes, then that's impossible, because there's a specific number of available private keys.

Specifically, you cannot pick a number outside the following range as a private key:


You're probably referring to the developers. They don't maintain Bitcoin; this task is being managed collectively by the network. They're the ones who contribute by coding.

Here they are: https://github.com/bitcoin/bitcoin/graphs/contributors

Anyone can.

To whoever you report it, if it's indeed a security flaw, we'll all gonna learn it.

Having just the testnet doesn't need too many resources, but I have my doubts for both mainnet & testnet & electrum server running for both of them. Maybe this isn't a task that can be managed by a RPi 4.

Yeah, I mean the directory of my Electrum server.

Yes, but how many gigabytes are the rest of them? The mainnet blockchain, the testnet blockchain and the electrum directory for testnet? My disk isn't exactly 1TB, but almost 980GB if I'm not mistaken.

I've indexed the testnet and will index mainnet in the future, once I'm fully synced with it, so this part is covered.

I was wondering if it's possible to run both mainnet & testnet from a RPi 4, including their Electrs indexes. I'm right now running both of them and it goes relatively fast. How much space would these four directories require? I've built everything upon a 1TB SSD external disk and I'm afraid it'll need more.

I haven't synced with the whole mainnet yet, though.

Δεν είχα επιθετικό ύφος, τουλάχιστον δεν στόχευα στο να έχω. Απλά έχω μπουχτίσει με τα κερδοσκοπικά κανάλια όταν έχουν να κάνουν με κρυπτονομίσματα και όχι με χρηματιστήριο. Δεν θα χαρακτήριζα αγενές το ποστ μου.

Από την απάντηση που πήρα όμως γίνεται να μην γίνομαι στερεοτυπικός με αυτά τα κανάλια;

Γνωστή κουβέντα αυτή. Μου θυμίζει εκείνον που θα πάει ενάντια σε κάποιον που είναι κατά του πρωθυπουργού με τη δικαιολογία «εσύ θα ήσουν καλύτερος;». Όχι, αλλά εγώ δεν θα καθόμουν να πείσω όλο το κόσμο πως είμαι ικανός, αφού δεν θα ήμουν! Έτσι λοιπόν και με το κανάλι, δεν είναι σωστή απάντηση αυτή. Εσύ που έχεις όμως και θέλεις να το συνεχίσεις το πράγμα πρέπει να υποστείς τις συνέπειες δηλαδή αυτές τις «αυστηρές κριτικές». (Ξαναλέω δεν ήθελα να φανώ έτσι)

Εγώ αν θες να ξέρεις βοηθώ την ελληνική κοινότητα όσο περισσότερο μπορώ.

Ναι το referral με πείραξε όπως θα με πείραζε αν σε κάθε αρχή του βίντεο έλεγες τι λινκ θέλεις να πατήσουμε και για ποιον λόγο. Με πείραξε γιατί οι μισοί που ασχολούνται με κρυπτονομίσματα μαθαίνουν μέχρι ένα σημείο που τυχαίνει πάντα να είναι αυτό που θα κερδίσουν χρήματα.

Ακόμα κι αν ήταν κάτι το ωραίο όμως, δεν το βρίσκεις λίγο ενοχλητικό να υπάρχει στις μισές περιγραφές των βίντεο στο YouTube με θέμα τα cryptos;

Τώρα, όσον αφορά τα παρακάτω, δεν έχει νόημα να απαντήσω...

“Έχει δικαίωμα να ασκήσει κριτική εκείνος που έχει διάθεση να βοηθήσει.” — William Penn

Κι όμως. Αρχικά, ο τίτλος περιέχει τη φράση «Στρατηγική Εξόδου» που στοχεύει σε καθαρά κερδοσκοπικούς λόγους. Δεύτερον, στην πλειοψηφία των κομματιών του βίντεο μιλάς για τις επενδύσεις σου και για αυτό που πρόκειται να κάνεις.

Δεν είναι πως μιλάς για τις χρηματικές μονάδες που χρειάζονται για να αποκτήσεις μία μονάδα Bitcoin, απλά είναι καθαρά κερδοσκοπικός ο σκοπός του βίντεο. Έχω παρακολουθήσει λίγο το κανάλι σου και έχω δει πως συμβαίνει σχεδόν παντού. Μιλάς πολύ λίγο για τα ζουμερά και αναφέρεσαι σε, προσωπικής μου άποψης, βαρετά πράγματα που ακούγονται και πολύ συχνά θα έλεγε κάποιος. Έχουν πολύ ψωμί τα cryptos για να μένεις σε επενδύσεις και σε ανταλλακτήρια.

Πάρε παράδειγμα αυτό το βίντεο απ'το κανάλι σου: https://youtu.be/dAJGcX8LzsY

Λέγεται “Κρυπτονομίσματα & Bitcoin | Πόσο ασφαλείς είστε;”. Με αυτόν τον τίτλο κατάλαβα πως θα μιλήσεις για τις αδυναμίες μερικών κρυπτονομισμάτων και του Bitcoin σε τεχνικό επίπεδο. Αντί αυτού μιλάς για τους κινδύνους του πλούτου σου.

Τέλος, με αυτά τα referrals σιχαθήκαμε ρε αδερφέ. Μια καλή περιγραφή λείπει αυτό το καιρό, είναι όλες γεμάτες με binance, bitfinex και trading bots.

Κάνε κάτι έξυπνο, κάτι ωραίο να ξεχωρίσεις εκτός κι αν θέλεις να γίνεις σαν τους άλλους YouTubers που βάζουν thumbnail τη φάτσα τους μαζί με μια πολλά υποσχόμενη πρόβλεψη. Αυτό είναι το feedback μου. 

That's the point of PoW, but Bitcoin is more than just a mechanism. I find its point lost if we assume that someone holds more than the majority of the hash rate. Whether they attack it or not; whether they replace the current chain with an empty one; whether they reverse a bunch of their transactions or not. Just because someone has more power than everyone else combined is enough for me to stop using it.

And I repeat, saying that you can “merely” censor the transactions is ironic the least.

In any case, it's in the entity's decision, not in the community's. We'd all be dependent on what they'd decide and we could do nothing in order to prevent it. The system would suddenly have a central point of failure.

An empty chain wouldn't weight that much. If we assume that each empty block is 80 bytes and the new chain's height is 700,000 whose work is greater than this one's, then it's a matter of 56MBs to completely destroy it.

Thanks @NeuroticFish!

But, what's the command line flag?  

I'm almost done with Electrs' setup. What's left is a donation address and a fancy server message. I remember how you could do it in ElectrumX, but in Electrs I have no clue. I've searched for it, but didn't actually find anything related with those two. It should be defined in the configuration file.

See yourself:

https://www.google.com/search?q=electrs+github+server+message

I'm quite shy to open this request as a “new feature” in their github (since it's not a bug), so that's why I'm asking you (first).

Further questions:

— In which wallet would you want to import them? Do you run a node or is the SPV your only option?
— Are the keys related somehow? For instance, is there a master public key in which you can derive them all or are they just arbitrary keys?
— Why do you want to achieve this? (optional, but appreciated if answered)

First of all, he or she imported 14,132 private keys and not 5,000,000. Secondly, you should never install closed-source software outside a trusted place. It could be something malicious and judging by the comments, it's most probably a trojan.

And why would the bold part be important? It seems insignificant to me. The word “merely” should be meant ironically here. If they can “merely” censor transactions, they can also delete the whole transaction history and make the whole system useless.

Yes, they indeed cannot force anyone to change the total amounts of coins ever issued, or increase their wealth from other people's money, but they can force the nodes to accept their defeat; to accept that their system is no more secure; that they essentially dug their own holes with the rules they all agreed to follow.
