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/117435I 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": 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? |

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. |

Could someone check post created by Life_Saving? I saw his technical non-sense post just now. |

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: 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).

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. |

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. |

The "xpub" that you were asking is listed in each of the descriptors.
You can get more information about the other data in help listdescriptors command.
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.  Source: http://bitcoindaily.org/bitcoin-guides/how-to-recover-bitcoins-bitcoin-core-wont-sync-export-private-key/(...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. |

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. |

Someone who is making a signed message function can include some random bytes inside the message to mitigate this kind of attack, but in the case of signed transactions, what is available? Perhaps adjusting the change output amounts by a few satoshis would introduce enough randomness in the transaction to defeat the manipulation caused by frequency scaling?
Each UTXO is unique, so shouldn't it count as "different" message? CMIIW. |

hello, have you heard of the website [SHADY LINK] I found this on github when I wanted to look for various source codes, it appeared on the first page , is this thing even legal?
I won't fancy that link you had posted there op and I would also advise anyone on thought of clicking it to be careful.  Please remove shady url from your quoted post. You could unintentionally bump position of that link on search engine result. is this thing even legal?
Probably no, since they include goods for illegal goods. But i doubt that website is legit (actually send illegal goods to your home). |

This is super important! Thanks for notifying me! I will try to find a way to avoid openssl. I can use sha256sum instead of openssl sha256 but I don't know what to use for ripemd160 and ec. Anyway, good catch! Edit: From what I read, there hasn't been an event that caused this change, but rather the fact that the attack space against openssl is much larger, due to its huge feature set. I mean, Core devs said that openssl does much more than the validation of the ECDSA signatures and therefore they changed it to something that does "just the validation". I agree with the choice, but perhaps it is an overkill to change it for this simple script I have written which only generates a public key from the private key. Core devs needed 3 years of development to produce libsecp256k1. I will look more into it! Yeah, the main reason was attack space. That's why i used term "concern". It's definitely overkill to replace OpenSSL entirely for your script, especially when it seems there's major change on OpenSSL organization and security after heartbleed[1].

Actually dogecoin is only used to store the file. But it's still cool to play DOOM on dogecoin ordinals explorer. Interesting part is that since it's a shareware copy nobody can sue on it!
CMIIW, but doesn't the creator or publisher still have right how their shareware is distributed? Somebody mentioned 20 doge as cost for it, don't know how accurate that is, but I guess we can say bye by to bitcoin ordinals and a flood to doge at these prices!
Full fee reward was under 15k for doge last 24h so cheap enough to inscribe a shitload of stuff there.
NFT already exist on altcoin, but Ordinals on Bitcoin manage to gain popularity. So i doubt those people would move to altcoin again. |

- The methods I used are included in the openssl library. I have used sha256, ripemd160 and ec.
FYI, Bitcoin Core stopped using OpenSSL due to security concern[1]. - Coding-wise, it sucks, I know... But as I said, it's my first effort with bash scripting.
Don't be discouraged. I use Linux daily, but i almost never create Bash script. And when i do, it's not as good as yours. [1] https://bitcoincore.org/en/2016/02/23/release-0.12.0/ |
