Bitcoin / Electrum / Re: Electrum Not Connecting to Any Server
|
on: June 20, 2021, 07:46:59 AM
|
I just installed Electrum today, 6/19/21, on a Win10 machine. When I open Electrum to the default wallet, it does not connect to any server. The round icon in the lower right hand corner remains red. What I've tried:
- Unchecking "Select Server Automatically" and tried assigning 10 different servers, but round icon remains red.
- Disabled windows firewall and my anti-virus, but no change in behavior.
- I went into windows firewall to allow the access to Electrum, but Electrum isn't even listed.
I seem to be out of options. Any ideas?
Your machine time might be out of synch with Electrum servers. Close Electrum client. Go to Win10 Settings, then click "Speech, region, date' , choose Date&Time and click Synch now. You may check your time on the site like timeanddate.com and such. If it's correct launch Electrum client again. |

What about Shamir's secret sharing? I've seen quite a few implementation of it but have yet to check the threshold for the number of compromised shares before it comes trivial to get the entire secret. I've read about it several times, and each time realized I can't use it. Just look at Shamir's Secret Sharing on Wikipedia: it's complicated. Which means even if I'd be able to use it, I wouldn't fully understand it, which means I have to trust whoever created whatever software I'm going to use. For the record, I'm not aware of any standardized implementation and some of it has been plagued with certain vulnerabilities. Probably not as convenient as the system that you've mentioned. It's been around for years ( Shamir is mentioned 600 times on Bitcointalk since 2010) but hasn't really been implemented anywhere. It's probably going to be mentiond for the coming 10 years too, and my guess it nothing will change. That's why I like Ian Coleman's simple 3 cards: it's very easy to understand. On a mathematical level it's probably inferior, as far as I understand Shamir's system doesn't give you any information if you have just one share, but it's much more practical. By and large, EIP-3450 has proposed the standardized SSS algo for BIP39 mnemonics. Jelurida has already implemented SSS to protect Ardor account password. The latter is used in Ardor to generate private key and relevant public address. I use the three-of-five SSS scheme for secure sharing of my Ledger SEED between my relatives. |

Bitcoin / Hardware wallets / Re: Ledger fake device Warning!

By and large, being flashed with new firmware, Ledger can be considered to be safe device. If upgrading fails you might suspect that the wallet was either counterfeited or tampered.
If you think that the device in your hands is malicious, then the last thing you want to do is plug it in to your main computer to attempt to update the firmware. Doing so allows any malicious software on the tampered device to infect your computer, never mind showing you fake prompts asking for your seed phrase. My point was that even officially bought wallets must be suspected and not be used until the next firmware update. Regarding malicious software on the tampered device - nowadays every child knows how to disable USB autorun, so I didn't stress this. Just in case, make backup image (say with Macrium Reflect) of your pristine OS to restore it after each and every use of suspected USB. |

Bitcoin / Wallet software / Re: Best way to send BTC?
|
on: June 18, 2021, 07:50:00 AM
|
I want to send $533 to a company. I have $443.25 in my Coinbase account. And $110.56 balance in my Electrum account. Total of $553.81.
$553.00
- 533.00
$20.81
I believe the BTC transfer fee is around $20.00. How do I determine how much the transfer fees are from both Electrum and Coinbase to calculate or determine I'm sending the guy the correct amount of $533.00?
I would send from Coinbase to Electrum first and after transaction is confirmed make the second transaction from Electrum to guy's address. Doing this way would allow me to choose both the best time window for transaction when the size of mempool has the lowest value and the lowest fee using Electrum's options to do this. |

To be on the safe side don't use Ledger nano even bought directly from manufacture or official distributor until the next firmware update. By and large, being flashed with new firmware, Ledger can be considered to be safe device. If upgrading fails you might suspect that the wallet was either counterfeited or tampered.

Bitcoin / Bitcoin Technical Support / Re: How do i recover my bitcoins for an address?
|
on: June 17, 2021, 09:02:36 AM

I lost my computer in a house break-in some weeks ago, and searched high and low for my devices through gps tracking, but found no luck.....  Someone told me about this forum, and that i can find answer here. How do i recover my bitcoins. The wallet i used was bitcoin core but electrum reads my info. I can view the wallet from the info i have so far, but eveything is watching only. Not spendable. Need the seedphrase I only have the wallet,dat and btc address with valid amounts, Also have 7 words form the recovery, missing the other 5 words. The remaining words were kept on my ledger nano, but it was attached to the pc the time i wasnt at home. Any advice will be nice, I would write down those 7 words you are aware of and then try to recollect the missing 5 words by looking on the BIP39 word list. If you’ve ever seen them they’re still in your memory. The only question is how to get them out. Your brain can figure out itself what to do with that 2048 words and reveal missing part of your SEED in your sleep eventually. The alternative way to find them in your brain is ask professional hypnotist for assistance. |

Bitcoin / Hardware wallets / Re: Ledger Live 2.29.0 - Windows Users
|
on: June 16, 2021, 08:56:44 AM

Though they say automatic update verifies everything before installing I never use this feature in Ledger Live and rely solely on their official page that lists downloads along with sha512sum hashes. It allows me to verify manually the downloaded file to be sure that it was not corrupted (in either way, occasionally or intentionally) in the course of downloading. v 2.29.0 is over there. |

Bitcoin / Hardware wallets / Re: Safepal,Ledger,Trezor keep a backup of my 24 words and transfer to their server?
|
on: June 16, 2021, 08:35:45 AM

Hello,
Safepal, Ledger, Trezor say they don't keep a backup of my 24 words and they will not transfer my 24 words to their servers.
Because I still need to connect the above hardware wallet through the app, PC, every time I need to use them.
This makes me worry they might store my 24-word recovery phrase is randomly generated by the device and displayed when during setup, and then they will be transferred to their server.
So how can I be sure they're not lying? Is there any way to check this?
By and large, you can inspect every TCP packet ( say with WireShark or other reliable packet sniffers) transferred from your computer to network to find whether they're lying or not. All it takes is the capture the correct packet and decrypt relevant string in it if any. Good luck in you endeavor. |

You forgot to add the most misused word of them all -- Bitcoin.
Far far too many people seem to think that all crypto coins are "Bitcoin". They are NOT!!!
"Bitcoin" is NOT a generic term for all crypto coins - it is 1 specific coin. Only Bitcoin (BTC or BTC) is Bitcoin. All others are called altcoins or their given name such as LiteCoin, Doge, etc. The only all-inclusive generic terms for all coins is "crypto coins", "cryptocurrency" or just "crypto" for short.
Also might add that all the different coins also have their own coin-specific wallets and woe to anyone who sends the wrong coin to the wrong wallet...
Needed some elaboration. To be precise, when the first letter is capitalized then Bitcoin stands for the entire decentralized network. The word bitcoin without capitalization of the first letter refers to the coin itself. Users are mixing both terms very often and context they use doesn't reveal what they mean. |

Economy / Gambling discussion / Re: [Boxing] Jake Paul vs. Tyron Woodley
|
on: June 15, 2021, 08:30:40 AM

Anyway I would love to watch Tyron again in the boxing ring. He was known to have a striking footwork and I wander how much of it left to him after his lost fights. Regarding the odds, I would bet on Paul if it were not exhibition fight. 15 years difference and advantage in the reach makes him superior of Tyron. Tyron Woodley is on a loosing streak in MMA and he is trying to make the maximum amount before retiring and hence you cannot complain him. Tyron Woodley was known for his knockout power but now it looks like he is not in the best physical condition whenever he fights because he is not having the same explosive power he had. Whatever his motivations he deserves to win, I think. His knockout power should be merited Jake's full attention. Some times the last fight has the unique mechanism that discharged a special role in mobilizing all the physical and psychological capacities that lie within the human being....I'm recollecting Klytchko-Charr fighting ...that was a striking fight. |

You curiosity may be fulfilled by walletexplorer site. On the front page of that site there are plenty of links to services including those relevant to exchanges. Those links lead to wallets created by services. Following the link of your interest you may find what are you looking for. 95% of the time Wallet Explorer will not be able to identify the address as belonging to an exchange because Is this solely your guess or you can prove your statement by research? Okay, let's assume that 95% is correct (though I think this is very odd). Then, 5%-chance remains for success. Small step is better than standing still, it could pay off with a vengeance. At least I was able to identify bunch of addresses used by exchanges. |

Alternate cryptocurrencies / Altcoin Discussion / Re: What about Litecoin?
|
on: June 14, 2021, 10:41:20 AM

Agreed with your thought on transaction speed but not least important is their ability to be fully untraceable. Recent studies show that privacy is one of the major concern for those people who use crypto intensively in their life. Mimblewimble Extension Blocks (MWEB) feature which will raise the degree of confidentiality for LTC transactions is round the corner. Privacy is good for most market participants, but in the case of Litecoin, if MimbleWimble is launched on the main network, it can lead to delisting from exchanges, as was the case with Monero, Dash, Zcash and other anonymous cryptocurrencies. Perhaps this is the reason why Litecoin developers are hesitant to launch this update on the main network. Wow, never thought of the privacy matter at this angle. Do you think they will proceed with implementation of MimbleWimble into litecoin or postpone it forever? I think they need to negotiate with exchanges regarding the fate of LTC with MWEB feature and insist on not delisting it otherwise MimbleWimble is not worth the possible trouble. |

Elon Musk has announced that when there is “confirmation of reasonable (~50%) clean energy usage by miners with positive future trend,” Tesla will start accepting bitcoin for payments again.
By and large, he don't understand that in terms of environmental impact there are no difference between car bought for bitcoin and that one bought for dollar preliminary exchanged for the same bitcoin. That’s why he keeps going with his shit-tweeting. Market response evidences that some ppl still treat his words seriously, better to avoid this and forget about Musk. |

I do not understand, Signiing, broadcasting these payments....PLEASE HELP....
If you sign payment but not broadcast the relevant transaction it will never reach any bitcoin node .To propagate throughout the network transaction must be broadcasted after you sign it. Using Electrum click "broadcast" button after your sign your payment... " and Bob's your uncle!" |
