Wubi store whole OS on single file, so it might be difficult. But you could try using pywallet which scan whole hard drive. Here's a rough guide (assuming you use Windows), 1. Make a RAW copy of your HDD using https://hddguru.com/software/HDD-Raw-Copy-Tool/2. Download most recent version of pywallet at https://github.com/jackjack-jj/pywallet3. Download Python 3 at https://www.python.org/downloads/windows/4. Run this command. Change "D:\hdd_dump.img" with path of RAW copy of your HDD. Change "100Gio" to size of the RAW copy. python3 pywallet.py --recover --recov_device D:\hdd_dump.img --recov_size 100Gio --recov_outputdir C:\recovered_wallet

You can't clone my credit card.
Ever heard of credit card skimming? Ever heard of cards with chips in them? Ever heard of credit card s himming? See https://www.zdnet.com/article/researchers-create-magstripe-versions-of-emv-and-contactless-cards/Maybe I should open a new thread and entitle it "How to implment a freezing function in bitcoin" what do you think? Then we could talk about how to make that happen! See because CLTV freezes utxos. So freezing is not unheard of. It's just...
So far no one able to show their idea about to implementing "freeze" function without 3rd party, using same private key (to generate address) or other hack. So i doubt we'll see new idea. |

The tricky part is that an external drive formatted for use with either of these systems, likely won't be readable on a Windows machine.
I don't see how it's tricky. Usually you can get around it by format the external drive with NTFS format (on Windows machine). Most linux distro these days already include NTFS-3G driver, so usually you just need to mount it. |

How to.
--snip--
Those 4 "How to" require active intervention by admin, moderator and manager. I doubt any of them are willing to review the company or approve the user manually. I would suggest only enable signature if the user receive X merit within last Y days (for example X is 8 and Y is 120). The hardest part is determining X/Y value, but admin only need to do it once. |

If I were to also download an Electrum wallet set-up on my phone, could I access the same wallet without any problems? So it would be like internet banking, say, when you can view the same account through the web or on the app?
Yes and yes. But if you just want to see your wallet status (current balance, transactiion history, etc.), you could just create watch-only wallet by importing your current wallet's master public key (xpub). That way there's no security risk if your Android is compromised. |

It's neither simple or small idea, why don't we create soft-fork which introduce new quantum-resistant cryptography and payment scheme (such as P2QTR) in next few years? That way, there'll many years for Bitcoiner to move their funds to quantum-resistant address.

1. Is this wallet some donation wallet?
Unlikely, if they use single static address, usually it's shown on website which can be accessed by everyone. That means you can found the owner by simply copy the address on google search. 3. If not donation wallet, then what kind of wallet it can be as size of each transactions is small?
There are few possibility such as people who use faucet or do micro-task. P.S. One wallet might have more than an address, please use the term correctly. |

Before you guys crucify me, we decided to use Bitcoin Cash instead of Bitcoin due to the fees but we are looking into lightning possibly.
People don't care as long as your website doesn't say something like "BCH is the only good cryptocurrency". But consider accepting few popular cryptocurrency to attract more users. I saw ETH, LTC and DOGE sometimes accepted on merchant which sell digital goods. |

Just found a simple equation to balance supply and demand that could be easily introduced in btc source code:
next block size limit = previous block size limit + (total fee in the last period / avg fee in the previous period - space used in the last period) / block occupancy rate for the last period
The harder part is testing the equation on various network condition and accepted by the community. Now I challenge you to find an equation based on "not centralizing bitcoin too much".
See BIP 103. The exact number and equation definitely need more research though. |

So i just downloaded electrum but in the installing proces when i get to the wallet import i cant type the private key?
when i type the public key i can still click the next button but when i also type the private key it goes grey and i cant continue.
so i just entered the public key and proceeded to the wallet and it says that its a watching only wallet and i cant transfer anything..
What you should type is the private key. I don't have iOS device, so i can't help you directly, but you should find this menu/page which contain the private key. On the example image, the private key is blurred, but on your iOS device you should see it without blur.  Source: https://apps.apple.com/us/app/bitwallet/id777634714 |

Does this mean that Bitcoin's privacy problem is due to regulation (KYC) rather than the protocol itself?
Both. Bitcoin protocol isn't explicitly designed to protect your privacy, but KYC is bigger problem since most Bitcoiner use centralized exchange. Because if one were to use a KYC exchange, then presumably that would be considered a SPV wallet and even if they immediatetly transfer to their own cold wallet or Electrum, and use that for their future transactions, all future transactions will be linked due to the KYC?
Generally yes, but we don't know much they'll try to track/link you. If this is the case, doesn't that mean privacy can never be completely solved if KYC is enforced? Unless we go 100% peer-to-peer?
Mixer and CoinJoin could solve the problem, but usually your coin will be blacklisted and they might threaten to close your account. |

Given that each new transaction will be associated with a different public key (all of which can't be linked to each other), doesn't this already solve the privacy problem?
You still need to be careful when spend your Bitcoin. You could harm your own privacy if you spend Bitcoin from multiple addresses in single transaction or sending Bitcoin to same receiver in multiple transaction. There are other privacy concern such as using SPV wallet where the server know list of your address. |

#! /bin/sh
cd /home/joe/.config/@trezor && srm -llvz -r * && cd /home/joe/.config && rm -r @trezor
read -p "*** WIPED ---- @Trezor ---- WIPED ***" nothing
# In this example-only the user is assumed to be joe
You can replace joe with $USER for flexibility. cd /home/$USER/.config/@trezor && srm -llvz -r * && cd /home/$USER/.config && rm -r @trezor

Aside from @bob123 suggestion, you could use lsof command to see directory/file accessed by Trezor-suite. But it's not recommended since the output from lsof is big. lsof -p PID_OF_TREZOR_SUITE | grep 'REG|DIR'

So go back and use the multi-sig set up I suggested earlier in this thread. If someone steals one of your private keys, they can't do anything with it. You need at least two private keys to "unfreeze" the funds, and they can't wait for you to unfreeze and then attempt to steal your coins without having the second private key.
I honestly don't like the concept of needing 2 different private keys. I wish there was just a way to use a single private key. And still have the "freezing/unfreezing" feature. At this point, we're in loop. The only answer i can think is by creating cryptography signature from your private key.
OK. So it really can work is what you're saying? What i say it won't work if you use private key for freeze/unfreeze address and spend your Bitcoin. The hacker who have your private key will simply unfreeze and spend your Bitcoin.
It's my understanding that even though private keys are 256 bits long, the address space is only 160 bits long. So Satoshi didn't use all 256 bits, he left 94 of them for us to be able to think up some super duper amazing thing to use them for to add extra security! The problem is how? It's not as easy as I thought.
The extra 94 96 bits usually seen as minor security weakness since 1 private key address is valid for 2^96 address private key (ignoring different public key representation, different address format, etc.). |

Don't compare farming with open source software development. It's poor comparison because farming and developing software are very different. For example, updated source usually checked before it's accepted and become part of the software. My questions;
Why did Bitcoin which is an advocate of privacy join the Mr. Linus (public) farm instead of Mr. Secret's farm?
Then what's the point of Bitcoin? I would rather trust bank and government as long as the economy is stable. |

I plugged in my Raspberry Pi into my router and read it would be accessible by typing " http://umbrel" (on any device that’s connected to the same network as the Raspberry Pi); it doesn't work. In this case the Umbrel website indicates to use an IP Scanner to find the IP address of my Umbrel and to type that instead of " http://umbrel"; the address is nowhere to be found, I only see my router and my desktop's IP addresses. The correct address is http://umbrel.local, but it should accessible by typing your RPi's IP address. I suggest you to check whether your RPi can boot and connect to router by, 1. Connect your RPi to a monitor. 2. Open router setting and see if RPi is connected. Or just follow @bob123 suggestion, the repository for Umbrel OS also mention about security risk. Umbrel is still in an early stage and things are expected to break every now and then. We DO NOT recommend running it on mainnet with real money just yet, unless you want to be really #reckless.

--snip-- According to the article you cited, the 1000 limit of chained unconfirmed transactions is to allow things such as games to be played on the BSV blockchain. While interesting, I don't think there is a benefit to having every move every player makes in a game permanently recorded on a blockchain. As I noted, the miners should be able to quickly confirm many chains of 1000 unconfirmed transactions or any other spam attack on the BSV network. --snip-- You're missing the point, i don't care about the usage. My point is with higher chain limit, an attacker could create more transaction within short time before hitting the limit or run out of coin. I wonder if anyone has tried spamming this shitcoin's network with transactions that take too long to verify. Although I haven't checked BSV's code to see how much standard rules they enforce to prevent it, I know it inherits a lot from bitcoin (since it is a copy); for example the SHA256 exploit can't be used since by default BSV uses BIP143 (Transaction Signature Verification for Version 0 Witness Program) sighash algorithm for all signatures.
If someone plan to do it, i would suggest them to look for any operator, cryptography or feature which not exist on Bitcoin. I expect it's less tested or audited. |

It seems that my 4TB HDD (not my main drive) may be dying soon as it started to disconnect and connect at random times, but health status is still good and I can't find any bad sectors or the source of problem except one software detecting there is one Uncorrectable ECC error.
If you have spare power/SATA cable, try replace existing power/SATA cable on your 4TB HDD. So my question: Is it better to buy new HDD with larger capacity or SSD with 1 or 2 TB, and what drives are you using for running your Bitcoin nodes?
If you plan to use the storage for various tasks (e.g. storing video and backup OS), HDD (for NAS, server or 24/7 usage) is better option. I use 3.5" HDD for running few full nodes without problem. |

Thanks folks,
After tearing apart half the house, I found an old tablet with a bookmark to Coinbase on it. I tried one of my classic old logins and it worked! Amazing!! Last time I looked at that account there was like X in it. Imagine my surprise to see almost Y in it now. That is just a regular bitcoin account so I found out I still needed a wallet so I opened a bitcoin wallet too. I need to learn about what to do with these funds now. I think because the amounts are small relative to everything, im just going to leave everything as is.
The amount might be small to you, but big enough for scammer. I would suggest you not to mention how rich you are and beware with personal message (especially about investment, helping manage your Bitcoin or fake legal threat). But if i want to play with mining, i need the bitcoin wallet to mine into, right?
If you're talking about Bitcoin mining, you need serious planning (such as location, cooling and electricity cost) and decent capital (An ASIC cost thousand dollars, while PC with a GPU only cost hundred dollars). Thanks folks,
-snip-
But if i want to play with mining, i need the bitcoin wallet to mine into, right?
One of your Coinbase BTC deposit address is fine for most cases but a non-custodial wallet is a must. I'd suggest Electrum ( electrum.org) for Beginners/low spec PC and Bitcoin Core ( bitcoin.org) for Advance users with huge internet bandwidth, DYOR. I also suggest to move your Bitcoin to non-custodial wallet. |
