Bonus question: Would repeat naming, using and then deleting "Wallet0" actually REMOVE that info from a hard drive?
If you want to actually remove that from the hard drive, you should use external software to do it. For Windows you want to use BleachBit. If you're linux user, tools called shred should be available by default. However, if you use SSD, deleting the file normally (not moving to recycle bin) will ensure the file deleted permanently after some time because TRIM operation. |

Interesting that the original message was that the file was corrupted but now say parameter is incorrect. No idea what that means.
On windows, usually i would use chkdsk tool. But since the hard drive contain important file, i strongly recommend you to make a raw copy of your hard drive before doing anything else. On windows, usually i use HDD Raw Copy Tool to do it. I would post screen shots but no idea how to do that on this forum
You can upload it somewhere (such as imgur) and share the link. |

You can connect your ledger nano x wallet with full node if you follow this GUIDE from ledger website. Since OP explicitly mention about privacy and TOR usage, it's not good idea since Ledger is known for blocking Tor due to technical problem. I don't know if the wallet functionally works if you use your own full node. You can also use Electrum and your own Electrum personal server.
I also recommend this. Just make sure Electrum only connected only to your server before you connect Electrum with your hardware wallet. |

@Pmalek @bob123 @o_e_l_e_o you guys should share your opinion with Bitwala, the original author. A Bitcoin address is like a traditional bank account number. However, unlike a bank account, one wallet can have multiple receiving addresses generated by its public key.
You can provide those new addresses to whoever wishes to send you bitcoin in order to conceal your original public key. The creation of new receiving addresses is availed of for privacy reasons, however, the coins are still sent to the same wallet. Thus, only your combination of keys can access and move the newly received bitcoin.

I've seen few people says there's no point of having ~100K Bitcoin full nodes when each node do same thing. While those people don't mention environmental impact, it's possible someone will use such argument on topic "Bitcoin is an environmental disaster". Anyway, here's few defense 1. Bitcoin full node isn't resource demanding, even Raspberry Pi can run full node. 2. Full node can act as server to SPV wallet which give necessary data (block header, transaction, address balance, etc.) 3. Improve user's privacy Sometimes I feel like an atheist walking into a church.
I know I'm right, but nobody has an open mind.
Both atheist and religious people usually think they know they're right. |

Is there a way to do this using your CPU/GPU that would be faster than the ~6 seconds that the website takes?
1. Convert the code to another programming language which allow high performance and GPU usage (such as C++). 2. Search similar tool which run on your computer rather than on your browser. P.S. Read https://www.coindesk.com/bitcoin-protocol-hack-joke if you're thinking to steal Bitcoin. |

When you're in doubt, it's safer to use RNG proven to be secure (assuming the software let you enter your own entropy). Besides, researching whether the software use secure RNG could take some time. Usually i would rely /dev/urandomcat /dev/urandom | xxd -l 64

On reality, if government run LN nodes, it can used as honeypot to get few information such as IP address and other metadata (such as time and range of bitcoin is sent).
liquidity ... Pffft government wont give liquidity.. they can just gossip the network. then try every route and not actually fulfill any payment. but test which payments are possible at different values and cancel payment without letting it finalise. with enough attempts at enough times they can gather quite alot of info. at no cost LN node isn't equal liquidity. You still need to run LN node and make a channel to try possible routes, but you can refuse to route any transaction or actually make payment. Just a guess on my part, but I imagine that using Chainalysis secret tool in addition to running a WatchTower would allow for forensics to be observed on the Lightning Network Payment Channels. Their is no locking bitcoin requirement for WatchTowers operators to provide liquidity, it could be done at a minimal cost and may even earn some payment for the watchtower service.
Chainalysis already suspected doing it on Bitcoin network when they caught run lots of full nodes, so it's possible they do same thing for LN watchtower and server for SPV wallet (such as Electrum). |

What about bandwidth? I believe Bitcoin’s bandwidth needs, as a decentralized network, is very underestimated. Rate of growth for bandwidth is slow, and network latency slower, which means that block propagation speeds might not scale at the same rate if average bandwidth among nodes increases.
If block size limit isn't changed, that means bandwidth/latency requirement won't changed much while bandwidth/latency is slowly growing, which means bandwidth/latency problem won't make Bitcoin less decentralized over time (excluding blockchain size and IBD time). |

My god, this thread is an abomination to read, particularly due to loads of spam comments from people who post thinking they will actually be getting 1BTC!  Consider use "Report to moderator" feature to report obvious spam. - Tell us the size of your hard disk and C drive. Windows 7 installation writes about 20GB of files so your chances of recovery are (disk size in GB - 20)/(disk size) * 100% assuming after the installation, you did not install anything else, and in particular you did not download a bunch of movies or install a bunch of AAA games like Call of Duty, or copy large files from the E:/ disk, or do anything else that takes dozens of extra GB of disk space.
Is it really that simple? How about temporary files (such as when install windows or generated by application) and swap file (AFAIK it's about 1.5x larger than your RAM size) which could significantly reduce chance of recovery? (which in Linux will be named something like /dev/sda or /dev/sdb).
To find it easily, you could use software such as GNOME Disks which shows model/type of the drive.  Source : https://software.opensuse.org/package/gnome-disk-utility |

...one specific thing i'd like to be improved is better warning/error message which can be understood by regular user. How do the error messages look now? It depends on LN implementation/software you use. Here's few example for BlueWallet from reddit, 1. https://reddit.com/r/bluewallet/comments/atl0ne/api_error_try_again_later_code_9/What does "API Error: Try again later (code 9)" mean? Before getting this, I had an API Error saying something like "Payment in Transit". What does that mean?
2. https://reddit.com/r/lightningnetwork/comments/kyky1l/1_of_fund_stuck_in_blue_wallet_lighting/I am trying to withdraw all my funds from my Blue wallet on android. When I try to do this I will not let me send it all (API error: make sure you have at least 1% reserved for potential fees.) and I and trying to stop using this wallet and get all my Sats out. What is the correct way to do this? I have tried the exchange option and creating a lighting channel and they all give me the same error when making a full amount transaction.

It seems that is a marketplace and based on your purchases, you get some points/ vouchers (?). I check OP's link but I didn't see anything related to crypto...  I visited your site and it does not appear to be related to cryptocurrencies or any blockchain project/protocol.
I searched for Blockchain and couldn't find any details.
I was thinking same thinking, but after a bit further checking, 1. Looking at this help page (support.karpine[dot]io/kb/a5/how-to-earn-reward-tokens.aspx), it confirm the website doesn't use blockchain in any way, just your usual website where you get point by using their referral link. 2. I found this subdomain explorer.karpine[dot]io/default which looks like cryptocurrency explorer, but all blocks only have 1 transaction (transaction which give mining reward to miner). This is the only blockchain-related page i could found. |

What would the hard-coded checkpoint change if every node I connected is malicious?
I think he means when the node is programmed to accept a particular chain up to a certain block, then it's not going to consult any of its peers for blocks up to that point, only beyond that particular block. I don't know if that's what's done in Core (besides the Genesis block of course). That's what i mean. Bitcoin Core used to have one, but AFAIK now it's disabled. The code isn't removed though and can be seen at https://github.com/bitcoin/bitcoin/blob/master/src/chainparams.cpp. Electrum also have checkpoint, where it's checkpoint can be seen at https://github.com/spesmilo/electrum/blob/master/electrum/checkpoints.json. |

Take note storing blockchain files on external drive is a bit risky, if it's disconnected when Bitcoin Core is running, it might cause corruption and force you to perform reindex or even redownload corrupted blocks.

Some people says raising Bitcoin block size hurt decentralization because it increases cost to run a full node. Bitcoin block size limit remains at 1MB 4 million weight units in past few years, while hardware and internet continue growing. The growth could be higher speed, higher efficiency or lower cost. With that in mind and ignoring other factor (such as blockchain size growth, hashrate distribution and total of full nodes), does Bitcoin become more decentralized over time?
P.S. This is just my shower thought, so obviously it has flaws.

Why don't he just fork BTC or BSV and print another 21 million coin to his own address?
He probably understands that forking BSV, which effectively cuts the already small community down to half(or less than half), would probably end up totally killing the project(as if it wasn't dead already). At least it's proof he don't have influence on BSV as big as some people perceive. Hope he does it though, very excited to see Bitcoin Craig's Vision!  Can't wait what kind of feature he bring to BCV, but i bet he'll bring feature such as control key over BCV network  Additionally, if we use tree visualization, the coin position is very deep ├── BTC

1. Rarely makes transaction doesn't mean you only HODL, someone might buy goods (such as gift cards) on special occasion (such as birthday and national holiday).
I believe LN can decongest the base layer, and make fees cheap enough for all kinds of users. I believe otherwise, even LN whitepaper ( http://lightning.network/lightning-network-paper.pdf) on chapter 10 think, 1. On global scale scenario, 1MB block size definitely not enoug. 2. On scenario to support 35 million users, it uses very optimistic scenario where all users use LN and only make 3 on-chain transaction/year. In fact, most LN channel duration is only 2 weeks and not everyone will use LN. 2. It's not about good UI/UX, but fee to make 2 on-chain transaction which already mentioned by @Heisenberg_Hunter.
With the help of exchanges, and working together with Bitcoin custodial wallets, isn’t it possible for users to have their LN wallets sent with coins/incoming capacity opened to them? I admit, I don’t have all the answers, I offer only what’s in my stupid brain. My point is someone has to pay the fee for 2 on-chain transaction which used to open and close the channel. One of the main Principles of Bitcoin is, “no censorship”. If a node censors transactions, what’s stopping me, and calling for the other full nodes, to stop listening to it for misbehaving? By "a node censor transaction", how would node do it? I doubt refusing to broadcast or accept specific transaction categorized as misbehavior (CMIIW). |

You got me curious, so i downloaded Electrum 4.0.9 AppImage and tried importing few library and here's the result 1. Importing built-in library shows no problem >>> import sqlite3
>>> import datetime
2. Importing library required by Electrum ( https://github.com/spesmilo/electrum/blob/master/contrib/requirements/requirements.txt) shows no problem either >>> import qrcode
>>> import bitstring
3. Importing library installed with pip command shows same error >>> import jellyfish
Traceback (most recent call last):
import jellyfish
^
SyntaxError: invalid syntax
During handling of the above exception, another exception occurred:
Traceback (most recent call last):

File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'jellyfish'

However trying same thing with Electrum installed with pip from source code shows no problem. >>> import jellyfish
>>> import pandas
I think Electrum AppImage have it's own python and isolated from python or python library installed your OS. |

Does it have to be blockchain.com or can you switch to another wallet like Electrum? I had no success finding anything for the blockchain wallet, but I came across an old thread where someone created an Electrum forwarded script that worked back in 2013. I don't have the skills to go over the code, so I suggest that someone who knows what he is doing checks if this is safe to use and still works:
--snip--
I don't know if the code is safe (as in no malicious code), but i know won't work because the code is for Python 2 and Electrum 1.X. For the security aspect, it store password of the wallet on plain text, which isn't best practice. At very least you need to make sure only root only can read/modify the file. |
