Given that you can "buy" accounts... basing trust just on rank is not a good idea. There have been numerous examples in the past of "high rank" accounts being involved in scams. There have also been examples of "high trust" accounts being involved in scams as well.
There is technically nothing stopping you from attempting to provide escrow services... just don't expect anyone with any common sense to trust an account that's 18 months old and has made 48 posts.
Honestly, if you have some spare coin, you'd probably be better off getting into staking or DeFi "earn" etc.

Yeah... this new method of having multiple .asc files has kinda broken pretty much all of the older guides for verifying Electrum  It certainly caused me a few moments of "WTF??!?" when I attempted to do my usual "download .exe, download .asc, right click and select 'verify'" method of verifying the Electrum downloads when the change first happened  Hopefully, they take onboard the idea to just put all the signatures into the one file like the Bitcoin Core team do. |

Thanks o_e_l_e_o. Is this how everyone else has done it? Previously I could just update Ledger Live by clicking on the update button right? Suddenly, it was no longer possible to do that, am I right? Someone said that you had to update it manually by going to the Ledger website, but I didn't do that because I was afraid of downloading malware from phishing links. Does anyone know if someone has been infected in this way? What if I download a fake update, that's possible right?
Last month I didn't have access to my Nano S, now I have access to it because I came home, but I am worried if I am doing it the right way. Are you sure that I can just click the download button? What if I click the button and my coins are gone, that can happen right?
Looks like jerry forgot to switch accounts. Tagging Pmalek for being a sold account.  Obviously joking |

I was trying in a multi-sig segwit wallet.
So how would I give the input that I need to recover p2wsh address?
You can't create single address MultiSig wallets in Electrum importing singular private/public keys. You can only create "HD" wallets using Master Private/Public keys... and only by using the "New/restore -> Multi-signature wallet" option during wallet creation. To do what you're attempting to do, you'd need to use something like Bitcoin Core and the createmultisig command. I've done this in the past (non-SegWit) with Bitcoin forks like Bitcoin Cash and Bitcoin Gold to extract fork coins from 2FA wallets. |

Kraken team managed to bypass/extract PIN code in just few minutes from Trezor wallet, so it's obviously not that complicated if you have the proper equipment and skills.
That's slightly exaggerating what they did PIN-wise... what they actually did was extract an encrypted seed from the device using voltage glitching. They then decrypted that seed by bruteforcing the PIN. However, by that point... it was effectively just a "desktop wallet" type PIN encryption setup. All other hardware protections were gone because they had the data out of the device. If the device didn't have the voltage glitch exploit, the PIN system would be a perfectly adequate way of securing it (as devices like Coldcard and Ledger do etc)... unfortunately, the Trezor device is inherently vulnerable to this physical attack So, your only option is to use a "strong" BIP39 passphrase, because if your device is lost/stolen... then, as you say, any one with physical access and some relatively basic equipment can bypass all the other protections with relative ease. |

This tutorial regarding the ZeroMQ Interface might help: https://bitcoindev.network/accessing-bitcoins-zeromq-interface/Granted it uses Javascript for the handler logic, but it illustrates the fundamentals of how to configure your node to use the ZeroMQ interface, and what sort of data your handler will be receiving from it. |

I also heard people saying that SegWit is actually a block size increase. Wait what? So you can do a soft fork to increase the block size, and Bitcoin Core clients installed in 2015 and never updated will accept those blocks as valid and add those blocks to their Block Chain?
Am I understanding this correctly? Before SegWit, the Block Chain on my PC (running 2015 software) increases by 1 MB per 10 minutes on average. After SegWit, the Block Chain on my PC (running 2015 software) increases by 1 to 2MB per 10 minutes on average?
Not exactly... SegWit was a bit of a "workaround" to the block size limit. By putting a chunk of data into the Witness, you're theoretically increasing the block size for SegWit compatible nodes. Older Legacy nodes (like your theoretical 2015 software), just ignore the Witness part, strip it off and only store the "legacy" data, so will still end up with max 1 meg blocks. Also, as a note, the blockchain size increases by a maximum of 1 MB per 10 minutes on average for your old node... it depends on how full the block actually is... sometimes they're empty or only have a few 100s or 1000s of bytes. |

Fairly sure that the wallet.trezor.io system didn't store "state"... and it certainly doesn't now. So, as soon as you unplug the device, everything is "forgotten". When you reconnect and unlock the device, then it does the account discovery again. Difficult to test given we don't know what version of software they were using.
I've certainly never seen it show both "default" and "passphrased" accounts in the UI at the same time... and I've had my Trezor since 2016. But yes... it's possible that this behaviour changed at some point between then and now. |

If you haven't seen this video, it's a very good review of the device. A bit too long maybe. I had not... thanks for the heads-up. Based on that... I'd have to say that, as it stands, it isn't a device for me. Thing that I don't like with Jade is that Blockstream server is involved in operation to increase security (because there is no secure element) and I am seeing reports from people that it often shows timeout when you need to update firmware, etc.
Yeah, that was one of the things that bothered me when it was initially announced... the whole Oracle PIN server thing Granted, they have said they will be providing the code so you can run your own PIN server... which could be interesting if it was possible to add it to an Umbrel or RaspiBlitz setup. Still... having to rely on their infrastructure like that simply to use the device generally ends up causing issues for the end user... like when the backend can't keep up with demand like Ledger updates or Mycelium syncing etc |

you haven't come across anyone that said they couldn't see their legacy wallet? i think it have to do with segwit and trezor dont like to showing legacy it preferred to using segwit.
No... I mean I haven't seen any cases of someone who had a "greyed out" legacy account that they were unable to send funds from, that disappeared after they updated their firmware and/or reset their device etc. You are correct that Trezor doesn't "show" the list of Legacy accounts by default... but it shows the "Legacy Account" menu item and if you expand the menu item, it does show any existing "Legacy Accounts" with balance and transaction history. You don't have to explicitly go searching for them. Unfortunately, what we're left with is that we're essentially "guessing" based on a 2nd hand description of something that happened 3-4 years ago. |

Isn't Electrum a Bitcoin wallet? Why do you need to connect a proxy to a cryptocurrency wallet? Can you please explain in more detail why a proxy is needed and why it should be connected to a web wallet? Firstly... Electrum isn't a "web wallet". It's a desktop client (or mobile if you are using the Android version). Also, the proxy functionality in Electrum is not just for Tor... some folks might be using networks that are being "restricted" or filtered. Sometimes using a proxy server can bypass these restrictions and allow you to connect to the service that you're after, like an Electrum server  |

So I am new to the electrum community and recently opened a wallet and I believe I transferred my Bitcoin from coinbase wallet to electrum wallet and now I'm really confused as to what I have to do to get it to transfer it out of the electrum wallet. So ya I'd like to add it to the remainder of my crypto which I have in Coinbase. I'm somewhat confused... If you had the Bitcoin in Coinbase... and you wanted to add it to the remainder of your crypto in Coinbase... why did you transfer it to Electrum in the first place??!?  Were you just experimenting with Electrum or something? |

I created a electrum wallet at the start of the year. I then restored it from my seed sent BTC yesterday to another wallet and it still hasn't reflected in that wallet. I then logged onto my main pc but it doesn't show any transactions in my history how can I recover this? to see the transaction. my btc doesn't show in my electrum wallet so that means it hasn't been sent back for not being confirmed.
Where did you restore the seed to if it wasn't your "main pc"? It seems like you original restored from seed on a different computer or device and sent BTC... and that didn't work... and then you tried opening the wallet on your main PC and it doesn't show anything? Is that correct? It's been two days and the btc hasn't reflected in the receiving address and still nothing is showing on my electrum wallet. I used the original seed to restore the wallet, as that of the wallet I sent the btc from. I've read that I should try change servers on electrum but I'm not too sure how to do this? I will also try check the different wallets like suggested. On this pc it is the first time electrum has been logged onto it.
It sounds like the "original seed" you used to restore your wallet, was not the correct seed... if it was, it should show the wallet history and balance etc. Where is the wallet that you sent the btc from (ie. what device is it on)? Do you still have access to that wallet? |

And second question:
If you will find privatekey belongs to another person. is It something like 10% for found?
The second questions was dedicted that I read a lot of topics on this forum, and there were written about 10% , so I'm really instresting is that only "Imagine" people or what.
Are you perhaps referring to a "reward" that people often offer for helping them recover there wallets and/or private keys? I know in the past that I've helped people recover "lost" coins (passphrase recover, missing words from recovery phrases, fork coins in multisigs etc)... and often users have given me 10% (sometimes more) of the recovered amount as a reward for helping them out. As for what you should do if you "find" someone else's private key... that's something of an ethical discussion... what would you do if you found a wallet full of cash on the footpath? |

To avoid issues with opening wallet files in older versions that may not support any modifications to the wallet file format, Electrum generates this error.
In your specific case, it seems that he wallet file was either created with version 4.1.3, 4.1.4 or 4.1.5 of Electrum this set the "version" of the wallet db to 41... or the wallet file was opened with one of these versions and the wallet file was upgraded to this version.
Now, it appears that you are attempting to open it in a version of Electrum from 4.0.2 to 4.0.7 (these all use version 32 in wallet db).
Either use version 4.1.3, 4.1.4 or 4.1.5 to open the file, or restore in the older version of Electrum using your seed backup.

Once I put my passphrase in and I select the proper coin which "Derivation Path" do I choose,
Did you put your actual BIP39 mnemonic backup phrase from your coinomi wallet into the Ian Coleman BIP39 website? If so, you need to move all your coins ASAP, as you should consider that mnemonic compromised! Or did you put your BIP39 mnemonic into an "offline version" of Ian Coleman (downloaded and run on a computer not connected to any network)? That is still "bad", but not as bad as typing your mnemonic into a website. |

Curious to know if anyone has bought a Blockstream Jade device yet? I see they actually have stock on their online store... priced ever so slightly higher than the "original" listed price of US$39.99... they're currently showing as US$45.99. It always looked like quite a decent bit of kit at a relatively accessible price, if somewhat limited (no real altcoin support outside of Liquid Network assets) and currently missing some key features which the devs claim will be added via software update: More features will be enabled in the future through software updates, including:
- Camera for fully air-gapped transactions
- Hardware Wallet Interface (HWI) wallet support for compatibility with Bitcoin Core
- Independent PIN server support
Did anyone take the plunge yet? |

It also stops "mouse loggers" in conjuction with a Trezor One... theoretically, by monitoring where you click, an attacker could determine what your PIN code was if you were clicking in the same "pattern" every time you unlocked your device. By randomising the keypad, it makes this impossible. ... but I don't think that cracking short PIN number code is hard for any hacker, so I don't trust that PIN will save me from anyone except maybe kids or wife gaining access to coins.
Except that the time you have to wait between incorrect attempts increases by a power of 2... and then the device wipes itself after 16 incorrect attempts: Brute forcing the Trezor PIN
Trezor is protected by a PIN code, which can be up to nine digits long. If a good PIN is selected, it would take hundreds of thousands of attempts to get it right. Every time a wrong PIN is entered, the waiting time between the attempts increases by a power of two. The device automatically wipes itself after 16 unsuccessful attempts.
Even attempting a 4 digit PIN under those conditions is going to be quite a challenge... unlike say, attempting to crack a 4 digit PIN on a desktop wallet. |
