If I'm Satoshi Nakamoto How do I prove it?

FYI some people believe real Satoshi wouldn't return and would assume anyone who claim as Satoshi as fake.

Would an original Whitepaper doc be sufficient or do you think that there would still be critics? I know there would still be critics, Im just asking what do all of you folks think?

No. But rather than critic, there would be many disbelief and skepticism. faketoshi CSW attempt to forge several document/file (which found out by government) which makes people more careful against such proof.
442  Economy / Scam Accusations / Re: Testnet faucet abuser with 4 accounts on: February 01, 2024, 09:25:10 AM
This is a really good measure that will reduce the abuse of your Testnet; I don't know what the point of them draining the Testnet Bitcoin faucet is. Do they think these are real bitcoins on the main networks? lol

There are a lot of crypto scams happening nowadays, and this testnet bitcoin can be used to scam others who are not aware that it's a testnet BTC that can't be used for anything and can't also be traded.
 
I have come across such a scam before where I saw someone's Coinbase wallet being loaded with one of these testnets of bitcoin, and the person said that it's real bitcoin. What surprised me about that is how they were able to make price reflections on that testnet BTC, like the same bitcoin value is showing and displaying in that testnet BTC.

As stated by @dkbit98, one possible reason is completing airdrop tasks. In past, a former Bitcoin Core developer state there are scam ICO which demands testnet Bitcoin.

There is a shitty/scammy ethereum ICO thing right now giving people shares in exchange for testnet btc, this is totally screwing up the usability of testnet and also causing antisocial dickwads to waste all our time begging for testnet coins without disclosing that the only thing they want them for is to make a quick buck.

I will be editing posts in this thread to remove any testnet addresses people paste.

Please don't give TNBTC to people who are just hoovering it up to paid by defi scams based on it.

Real testing just needs tiny amount, the people who "need" large amounts are selling it.  (technically trading it for defi testnet defi tokens which they expect to get converted into real value once that scams they are participating in go live).

This abusive and anti-social behaviour has made it hard for people to get testnet for actual bitcoin testing because they've drained all the faucets and conned the people that have historically given it out out of theirs.

It's also forcing bitcoin development to abandon testnet for testing.



I don't know what the point of them draining the Testnet Bitcoin faucet is.
and can't also be traded.
Unfortunately, there's a platform that provides unethical services for those who'd like to get something for their testnet coins [as much as I hate to say this, I think we need another reset].

Or use either regtest (testnet only on your device/network) or signet (semi-controlled version of testnet).
443  Bitcoin / Development & Technical Discussion / Re: SRC-20 vs BRC-20 on: February 01, 2024, 08:56:03 AM
To other reader, i just found SRC-20 technical specification which can be seen on https://github.com/hydren-crypto/stampchain/blob/main/docs/src20.md. Here are some interesting details,
1. They use MessagePack and Zlib to reduce size of the arbitrary data.
2. Rather than exploit witness data, it seems they exploit public key on P2MS (Pay to Multi Signature) address. It also means they don't need to create 2 transaction for single SRC-20 operation.

If i'm right, that means SRC-20 create less bloat compared with BRC-20. Nevertheless, i still believe they should use sidechain or LN for this kind of thing.

I don't know general consensus, but i believe both protocol should use one of Bitcoin sidechain rather than Bitcoin on-chain.

Storing the data somewhere else would be self-defeating since the inscriber's objective is to put the data in the most secure, most widely distributed place (which is the Bitcoin blockchain itself).

That's true. I mentioned sidechain since i don't like people storing arbitary (which usually have relative low importance) to Bitcoin blockchain, while wishing sidechain could be more popular.

I think in order to be mad at someone for spreading misinformation you have to determine if it’s being done because the person is an idiot and doesn’t understand something that they think they do, or if they are genuinely trying to spread FUD. Both are possible, but one is evil.

It's hard to measure such thing. So it's more practical to use different measurement such as whether the information could less to financial loss or how frequent someone spread misinformation. Although IMO most of them simply copy-paste whatever generated by AI they use.
445  Bitcoin / Development & Technical Discussion / Re: SRC-20 vs BRC-20 on: January 31, 2024, 11:26:03 AM
Hello everyone, as far as I understand, SRC-20 is better than BRC-20 regarding data permanency.

Both of them have same data permanency when it's transaction included on Bitcoin blockchain. I think you need to clarify your statement further.

Why are so less people talking about it?

Probably because there are so many standard about token/NFT created, although none of them are part of Bitcoin protocol.

What does the Bitcoin community think of this protocol?

I don't know general consensus, but i believe both protocol should use one of Bitcoin sidechain rather than Bitcoin on-chain.

447  Bitcoin / Development & Technical Discussion / Re: how-to clean up chainstate folder on: January 31, 2024, 11:04:46 AM
The command: --reindex-chainstate deletes the chainstate and creates a new chainstate from the blockchain.

Although as reminder, --reindex-chainstate will redownload whole blockchain.

So will that result in a smaller or significant difference folder size after such a reindex ? Please provide some folder sizes before/after if possible. Thanks a bunch in advance. What I still don't understand how two fully-synchronized non-pruned nodes can have different sizes of the chainstate. That makes no sense to me.

citb0in


Sorry, but i don't want to run reindex-chainstate since i only use HDD. But i don't expect much difference, where you only gain about 1GB free space. You better upgrade your storage, clear all cache on your OS and delete unused files.

I do come across wrong information too on other board of this forum and I wish a thread can also be specifically created where user can report  members who are steadily passing wrong and misleading information to readers.

@OP, I like the idea of this your topic. I don't contribute yet on the technical board because I don't know much about Bitcoin technical and I am still learning from the technical boardboard,  until I have a good knowledge about technical related issues, that is when I can comfortably make comment there.

It is better to keep mute or ask questions when someone don't have any knowledge about what is being discussed else they will just give wrong information.

Yeah, wrong information happens on all boards. But on technical board it's especially worse since there's expectation people know what they're talking about.


This user continue to spread false/fake information.

Electrum primarily supports Bitcoin. If your friend is dealing with a different cryptocurrency, they should check whether Electrum supports that specific coin. Importing private keys or seed phrases comes with security considerations. Make sure your friend understands the risks and takes appropriate measures to keep their private information secure. o import cryptocurrency into Electrum, your friend will need the private keys or seed phrase associated with their wallet. Ensure they have the necessary information before attempting any import. Electrum itself doesn't charge fees for importing funds, keep in mind that the blockchain network may charge transaction fees. These fees are usually variable and depend on network congestion and transaction urgency.

1. Electrum only support Bitcoin.
2. While there are Electrum fork which support altcoin, usually it have different name. For example, Electrum-LTC or Electron Cash (for BCH coin).
3. Import private key doesn't create new Bitcoin transaction, so there's no point mentioning TX fees. It's only relevant if he's talking about sweep private key.
4. It doesn't really answer OP's question.

During the wallet creation process, you may have the option to set up a BIP39 passphrase. This is an additional word or phrase that acts as an extra layer of security.
If you choose to set up a passphrase, make sure to remember it or store it securely.

This reply created for thread about Electrum, where Electrum doesn't create BIP39 words but rather Electrum Seed Version System (https://electrum.readthedocs.io/en/latest/seedphrase.html). In addition, this reply doesn't answer OP question at all.

Do you have personal experience or know documentation that --reindex-chainstate actually reduce chainstate size? After all, chainstate basically just LevelDB (key/value) database.
His chainstate folder is 11GB in size and based from his post history, he's been using his node for a few years now.
On the other hand, I have a recently fully synced node with 9.8GB chainstate folder.

Good point. I just found out size of my chainstate folder has smaller size.

The command: --reindex-chainstate deletes the chainstate and creates a new chainstate from the blockchain.

Here's a post in bitcoin stackexchange that explains how it work: https://bitcoin.stackexchange.com/a/117435

I already know LevelDB has some optimization, but didn't know it doesn't fully optimize/reduce size of it's DB files. Although as reminder, --reindex-chainstate will redownload whole blockchain.

CMIIW, but doesn't the creator or publisher still have right how their shareware is distributed?
AFAIK with shareware all that is required is that the Credits list the original creators/owners, it not be modified, and that it be provided for free. It can be distributed in any form.

1st result when searching "shareware":
Quote
Shareware is commercial software that is distributed free to users, eventually either requiring or encouraging users to pay for the continued support of the software. You might see shareware in formats that paywall advanced features or offer the full package for a limited time.

I see, but few website shows conflicting information. For example,

Shareware

Copyright law also protects shareware. Shareware provides users the opportunity to try software for free before deciding whether to buy it. Shareware may be a more limited version of the program available for sale, and is also restricted by license. Typically, the license restricts shareware users from modifying, copying or distributing the shareware in any way. Continuing to use shareware after the designated trial period is an infringement of the copyright in that shareware and may constitute piracy.

Were Shareware CDs Legal?

Shareware CD sellers operated in something of a legal grey area. Ostensibly, they only collected fees that covered the cost of manufacturing, printing, and distributing the disks or CDs. But let's be honest: If it weren't profitable to sell a disc of free software, very few would have done it.

What do you think?
452  Bitcoin / Development & Technical Discussion / Re: how-to clean up chainstate folder on: January 30, 2024, 10:35:49 AM
If your node is running for a few years now, re-syncing Core or --reindex-chainstate may produce a more "optimized" chainstate
but it wont be a significant change in size, maybe a reduction of 1GB at best.

Do you have personal experience or know documentation that --reindex-chainstate actually reduce chainstate size? After all, chainstate basically just LevelDB (key/value) database.

This of course goes beyond the actual purpose of a pruned node.

But it's technical limitation of pruned node, since you need all "spendable" UTXO to verify all new TX/block.

Why does the folder content of chainstate rise to this immense height?

1. Ordinals (mainly BRC-20 token).
2. Rising Bitcoin popularity.

What is the best way to proceed in such a case?

Allocate more storage. I don't expect Bitcoin Core will implement compressed chainstate feature.

Edit: there's possibility this user also use AI to create posts, see https://bitcointalk.org/index.php?topic=5456516.msg63583674#msg63583674.

User: Life_Saving

initiating a reindexing process can help optimize the database and reduce the size of the chainstate folder.

Use the following command:

Code:
bitcoin-cli -prune=550 -reindex

Non-sense post,
1. Reindex doesn't reduce chainstate folder. Based on https://bitcoin.stackexchange.com/a/117435, --reindex does reduce chainstate size if you already run node for long time. But since the goal only about reducing chainstate folder, using --reindex-chainstate is far better option.
2. Running --reindex or --reindex-chainstate on pruned node means Bitcoin Core redownload whole blockchain.
3. The command itself is wrong. bitcoin-cli only used to interact with Bitcoin Core JSON-RPC.

If he posted correct command and someone who run pruned node copy-pasted it without understand what it does, he/she forced to redownload 500GB+ blockchain which took few days (which depends on internet and computer hardware).

Mining using the FutureBit Moonlander 2 -

Hardware Setup:
  • Connect the FutureBit Moonlander 2 to your computer using the USB port.
  • Make sure the miner has a stable power supply, and consider additional cooling solutions if needed.

Mining Software:
  • Choose mining software compatible with the FutureBit Moonlander 2 and the cryptocurrency you intend to mine (Litecoin, in this case).
  • Download and install the required mining software on your computer.

Configuration:
  • Configure the mining software with details specific to the Moonlander 2, such as its device ID and the mining pool you want to join.
  • Consult the documentation provided by both the mining software and the Moonlander 2 for precise configuration settings.

Mining Pool:
  • Join a mining pool to increase your chances of earning rewards consistently.
  • Obtain the stratum URL and port number for your chosen mining pool and input these details into your mining software.

Wallet Setup:
  • Create a cryptocurrency wallet to receive the mining rewards. Ensure the wallet is compatible with Litecoin or the cryptocurrency you're mining.

Start Mining:
  • Launch the mining software and monitor its output for any issues.
  • If everything is configured correctly, your Moonlander 2 should start contributing hashpower to the mining pool.

Monitor and Optimize:
  • Regularly check the performance of your mining setup, including hashrate, accepted shares, and any potential issues.
  • Consider adjusting settings or exploring overclocking options to optimize your mining efficiency.



Looking at official guideline for Moonlander 2 at https://www.futurebit.io/moonlander-2-support, there are few inaccurate things.
1. You must to download required driver for Moonlander 2.
2. You don't need to specify the device ID. Mining software usually automatically detect your USB miners.
3. This reply isn't relevant with OP's question. OP only ask about possibility of solo mining with Moonlander 2.
455  Bitcoin / Development & Technical Discussion / Re: One more question regarding collisions on: January 30, 2024, 09:57:44 AM
That LBC statistic must be incorrect because a single 4xxx level card should be able to do 90mkeys/sec entirely on its own, and 50-100 times that if it does a linear scan of the private key space.

Looking at https://lbc.cryptoguru.org/about, it looks like they only perform 3 performance optimization and they use software called "GPUAuth4All" for GPU brute-force. I expect it's combination of optimized GPU usage and lack of interest towards LBC.

The aim of my previous post was to show that there are some  fantastical ppl who put their efforts on finding collision.

Assuming you trust them, especially with their closed-source software which have remote-execution capability.

Okay, it looks like I need to learn more about the command line. (I have a long Mac history, but virtually no DOS/Linux experience, so my shell/terminal skills are very very very poor.)

You don't have to learn about using terminal, since you could just use built-in Bitcoin Core console (see image below). Although since you already own computer with Linux, you'll benefit from using terminal in long term.

(...although it still is a long and bumpy road. Even for tech-minded people like me. It really must get easier in the future...).

I may sound like a broken record when I highly recommend to have a look at https://learnmeabitcoin.com: the beginner's pages are a fun to work through and the more technical sections explain a lot of Bitcoin's details in a nice and informative way. At least I like it very much, recommend it often and regularly go myself there to refresh my knowledge.

And Sparrow wallet meant for power user. IMO average people should use more friendly wallet software such as Blue wallet.

On Pawnapps you can earn only $9.60 per month if you keep your internet open for 24 hours so you're offer is just too good to be true.

I don't think it's too good to be true when AFAIK you can't find VPN or dedicated server which meet OP specification with rent price less than $75/month. In fact, i find OP's offer isn't attractive unless you happen to own such high-end server with fast internet connection that you currently don't use.

I have seen that this forum does not consider it inappropriate when some member makes a post or thread about a competing forum. I am a member of other popular forums and they do not allow mention of competing forums as it is free advertising for them.

I doubt there are many forum or places which do such thing.

What is the opinion of members about this?

It's poor suggestion.

Is it fine allowing members here to promote or mention competing forums without paying this forum owner or taking his permission  ?

Yes, we already can discuss service on "Service Discussion" and promote service on "Service Announcements". Even social media doesn't forbid you to talk about competing social media. In addition, member occasionally share interesting topic or article from competing forum which create new discussion in this forum.
459  Bitcoin / Bitcoin Discussion / Re: Hypothetical ETF disaster hardfork on: January 29, 2024, 11:12:32 AM
To me it seems evident at this point that all the ETFs are is an attempt to control the network. They want to centralize the supply in the hands of a few actors (ETFs) which are ultimately all the same hand at play (the US government in this case) which then will proceed to attempt to fork the network for whatever agenda that is trying to be meet with that. It is literally on the documents:



So while this may be bullish for the price now, we'll see how this turns out eventually when shots start being fired.

Whoever write that is stupid. They should choose all forks which have running network and doesn't have very low exchange rate. Although rather than attempt to control the network, IMO it's more plausible they want to rip-off ETF buyers.

How can I mix Bitcoins with minimal fees? So that the output is pure AML.

I don't see correlation between minimal fees and pure AML (as in "clean" coin). You might find mixer which claim you receive "claim" coin, but it can't be verified especially because each service may have different way to determine whether certain coin is "clean" or not.

Is it possible to split the transaction into many small ones?

It's possible by creating multiple mixing request, but that means you pay more for TX fee and fee imposed by mixing service.
