Before answering the questions, I want to say that I haven't used Jade with a Blockstream's companion app (BS Green). I use Jade with Sparrow and I have also tried it with Electrum. Therefore, there is a big area regarding the Jade, in which I can't comment anything unfortunately. I am refering to the integration with their companion app and, as a consequence, I am also refering to the Bluetooth usage. In fact, my Jade's BT is always turned off. Technically, a major difference is that the seedsigner doesn't generate entropy. So you must enter your own entropy by flipping coins or throwing dice. They do have an option to generate entropy from a picture you take with the device's camera. I can't comment on the technical part of it, though or how secure such seeds are. I hope the Jade has been put under severe tests to verify that the generated entropy from the device is strong enough. It's not exactly the most popular HW (which is also true for the Seedsigner) and surely doesn't generate as much interest as the major brands. [/quote] Sure, I dislike the entropy generation using the camera, it feels very wrong, even though it may be not. Jade also uses the camera to gather some entropy bits. It also uses the battery state, the cpu usage, some CRNG, the bluetooth etc. [1]Blockstream has never been very popular. I don't know why. I am not a fan, but I have never observed anything to disturb my confidence against them. I am okay with the Jade, but nothing more than that. You forgot to mention the battery. How do you like its performance?
Yeah, sorry, I totally missed the question. Well, the battery is good, I have never had problems. To be honest, I don't sign a lot of transactions with it. In the past couple of months, I have signed approx. 10 - 15 transactions. Each transaction takes about 5 minutes, in which I turn on the wallet, I scan the QR code, I scan the TX, I sign the TX and then I export the PSBT to be scanned from my "broadcasting" wallet (mostly Sparrow). So, let's say 15 transactions x 5 minutes each = 75 minutes. It's been approximately 60 days in which I have done these operations. My battery at the moment is still a little below 50% (there is no percentage indication, so my estimation is based upon my ability to interpret the half-loaded battery symbol. I don't really know if it's good or not, but it feels "okay-ish". [1] https://help.blockstream.com/hc/en-us/articles/9640569620761-How-does-Blockstream-Jade-generate-it-s-recovery-phrase |

<Snip> It seems like an interesting device, especially for its airgapped nature and affordable price. I might consider buying one. How long have you had it, and how satisfied are you with the battery performance? Since you mentioned Seedsigner, what made you buy the Jade and not the Seedsigner, for example? They are quite similar in several ways. The SeedQR is an invention by the developers of Seedsigner, unless I am mistaken. Have you discovered any major cons or do you regret buying the Jade? I think it must be approximately 1 year since I bought it. Perhaps a bit more. Well the seedsigner is fantastic but I wasn't able to find an RPi Zero (the one without the WiFi adapter). The jade, came cheaper and more convenient for me, so I bought it. Technically, a major difference is that the seedsigner doesn't generate entropy. So you must enter your own entropy by flipping coins or throwing dice. When it comes to backups, the Jade allows you to export the QR code in compact mode, whereas the SS allows you to export both compact and "not compact" QR codes. The SS is closer to my general mentality but the Jade is silently doing its job very well and comes handy when you need it. BlackHatCoiner has a brilliant guide for the SS. When I go home I will share it, unless he does so before me. I wouldn't recommend the one or the other, they both work well. The SS is better in terms of privacy. In fact nobody knows what you want the spare parts for when you buy them. The Jade is super easy to use and comes very handy. |

Now it makes sense. So criminals buy fake IDs and use them for forgery. Yeah I am not surprised, it just never crossed my mind that the way to buy the IDs is from KYC exchanges. But since they require KYC, you can be sure that at least they own the information about their clients. If they are willing to sell it for illicit usage, is a whole other story crime. |

I would rather use the SeedQR method instead of QR PIN unlock if I had a Blockstream Jade. It's quicker to gain access to your hardware wallet by just scanning a QR seed code then scanning multiple QR codes both on the hardware device and a secondary device. It's true though that you need some time to set up your SeedQR, but it's worth it.
Yes, it's worth it. Definetely. The way I use Jade is: Backup system:For each wallet I hold 2 backups, as follows: - Backup 1: Seed phrase, QR code
- Backup 2: Seed phrase, QR code
Obviously the backups are in separate locations (the one is easily accessible). Usage:Every time I want to use Jade, I do the following: 1. Turn it on. 2. Scroll twice and click "Options". 3. Click "Temporary signer". 4. Click "Scan QR". 5. I do scan the QR code and my wallet is ready to sign transactions. 6. I turn Jade off. The memory is automatically flushed, so if you turn it on, nothing is saved. So I mostly use Jade as the SeedSigner and after each usage, nothing remains in Jade's memory. So if someone gets access to it, they can't do anything. Obviously, if they get access to one of my backups, then my funds are gone. But the device itself can't help someone to compromise my funds. |

One of the biggest steps for the open source was Github, they changed the rules by offering a service where anyone can upload their codes and let the community make any changes to it, so if you want to support, I feel the GitHub guys are the ones that we have to say thanks to.
Let me say Git in general. Or perhaps Version Control systems in general, because Git isn't the only one available, but it's the clear winner among them. Having said that, people can contribute in various websites that support Git, like Github, Gitlab, Bitbucket etc. I think (fun fact) that Gitlab is the only one that is still open source, as a platform. Github is owned by Microsoft and Bitbucket by Atlassian. But it doesn't really matter, the conclusion is that open source is hugely benefited from Git. |

Once we do the KYC, we cannot undo that. My identities are already online and I never know if their 3rd party provider going to sell my KYC info on the darknet or not. I don't know if you are aware or not, but a well-known exchange accepts the claim that their 3rd party partner (who does the KYC process) sells the user information on the internet.
I am not aware, but to be honest, I am also not surprised. I am not sure why the info is worth selling/buying. I mean, I can totally understand that governments may want to surveil bitcoin and, in this effort, they will need to ask KYC exchanges for clients' info. But, who else would be interested in buying them and why? Marketing companies? Or anything more shady? |

So. The votes have been counted! I think that within a week we will make an announcement. It's funny, but BitcoinGirl.Club took 3rd place in the Miss Bitkintalk category, and since the winners of this category need to confirm their claims to the title, someone will have to show their tits.  Now we are even more excited! If BitcoinGirl.Club didn't come first, who did? Was it really a girl this time?  Haha, speaking on behalf of the (obvious) winner of the Miss Bitcointalk category, I can say that she will not feel good reading this  Not because of the tits part, but because she will definetely argue that the place for miss bitcointalk should be open for any human (or perhaps not even human) being that is willing to identify themselves as a "miss". I abruptly feel the need to make a proposal. How about we increase the total Miss Bitcointalk places from next year?  +1 |

Obviously the idea of supporting open source projects is good. I totally get the sense of your topic and I agree with you.
For instance, you said that we should use DDG instead of Google and Firefox instead of Chrome. I agree with you because it is a matter of privacy and Google is notorious in this field.
However, there are products that we still need in our lives that are produced by companies and their code is closed source.
When there is not an obvious matter of anti-privacy pro-censorhip technologies used by a company, I see nothing wrong in supporting (by paying) their products.
For instance, I use lightroom for my photography, because I love it. I also pay some subscriptions for other services that I love. I don't believe companies should stop existing, or that we should stop using their products.
To summarize:
1. Yes! Open source is fantastic and we should encourage developers by either writing code, or by using their software.
2. We must do our own due diligence and demand privacy. So when we know we can't have it, we must take action and perhaps stop paying a product.
3. We should be allowed and encouraged to pay for products and services that we like, no matter if they are open source or not.
4. Open-source doesn't always mean, better and safer.

Just like everyone, technically coins sent to addresses of which nobody knows the private key that created them, doesn't mean they are gone forever. There is always a chance (close to 0), that someone may find the necessary key to unlock the coins on these addresses. - Coins that were lost due to coinbase transactions having the same hash.
Has this ever happened? Is there an example of such a case? |

apogio, the new intern of Merit Cycling Club, fully deserves this rank up! Bravo, apogio! I hope your path to becoming Legendary will be as smooth as it was until this moment  Haha, well, let's say I have learnt from the best. Thank you buddy. By the way, I am not a hero member yet, unless the scraping mechanism identifies the merit requirement and not the activity requirement. I have enough merit to be a hero member but my activity is still a little low. |

It depends, if they are tainted linked to millions of dollars from selling drugs they may bother. You never know who sent you the coins. The problem is evident. They would try to contact theymos I guess, then check logs and so on. But im talking about buying in real life. You buy something in real life, and they will know who you are, even if you don't exchange personal details, you showed your face, there's cameras everywhere nowadays etc. If you don't see a problem of using BTC to pay someone and end up in some sort of investigation about drugs or whatever then I don't know what to tell you.
If you pay face to face, what is the difference between choosing Monero, Bitcoin or FIAT? Cameras will still get a picture of you. The vendor will also know your face. If you pay online, you must use a shipping address. This detail will be the same, no matter if you use Monero, Bitcoin or FIAT. It is basically a lottery everytime you deposit or pay someone with BTC where you hope your coins are not tainted. Chances are very low yes, but it's still there.
How is this different from what I said above? I will quote myself again: If you are worried that you own coins from illegal activities, let me tell you that anyone potentially owns this kind of coins, even if we use coinjoins.
If you don't see a problem of using BTC to pay someone and end up in some sort of investigation about drugs or whatever then I don't know what to tell you.
I never said that it is not a problem. All I said is that I find it pointless to try to avoid it. If someone gives you $100 in dollar bills and you try to deposit at a bank, then if the serial number of the bills is flagged by the authorities, you will have the exact same issue. I am just saying this because it looks like everyone who uses the "tainted" coins arguments seem to forget it. Anyway, it is obvious that we have very different opinions and that you follow the "tainted" coins approach / idea. I don't think we will ever agree, so, I think our arguments have been said and anyone can make their own opinion reading them. |

If you or others are using centralized exchanges providing the KYC, don't you think they are using it in the wrong way? What is your argument against my statement? Would you like to elaborate more about it?
I agree in general with your statement. Playing devil's advocate though, since I have been there, when someone first starts learning about bitcoin, they may not be very knowleageable in terms of privacy. So, I 'll speak for myself here, saying that, at first, I knew I had to take my coins off of exchanges, so I did. But, the mistake was made... I bought some coins through CEXs because I wanted to buy bitcoin as soon as I learnt about it. I was fascinated by it. Then, I joined the forum and I started going deep down the privacy rabbit hole. This is where I decided to stop using CEXs. But, I mean, mistakes can happen. The point is, we should fix them. |

Correct mate, when they are actually participating in a discussion with highly ranked members are discussing they are also getting more advanced knowledge about Bitcoin, forum and crypto currency at large.
Reason few are not getting involved with discussion where highly advanced ranked members are discussing are because they're somehow shy or scared to be attacked by their mistakes when they make any. Some newbies are types of people that doesn't like abuse's so they respect themselves and are very sensitive and mindful of the kind of posts they make and the kind of replies they do.
Sure, but that's why we discuss it here, because in my opinion this should change. I am not implying that newbies should go out and write stupid posts, but I am confident that there are a lot of knowledgeable newbies who try to establish a good reputation in here. We 've all been there! Haven't we? |

Do you think Bitcoin has gone against Satoshi Nakamoto’s original intentions and embarked on a non-decentralized path?
Yes, but it is normal. I mean, as time passes, more and more people get to know about bitcoin. Many of them dive deeper inside the rabbit hole and they decide to mine and run their own nodes. These 2 actions improve bitcoin's decentralization. So as far as I am concerned, bitcoin is more decentralized now, but if you want my opinion, it could have been even more decentralized, especially in terms of nodes. Because running nodes is much much cheaper and easier than mining. So, I reckon that the number of active nodes (we can only estimate how many there are), should have been larger. According to bitnodes there are ~50k nodes. Of course the real number is higher, but again, I would like to see it growing much more. |

By all means, newbies should engage to any conversation they want. By that I mean that newbies need to gain knowledge, just like everyone does. So, commenting on threads of highly ranked members is encouraged.
Don't forget that highly ranked doesn't necessarily mean "more reputable". In this forum, reputation is difficult to be earned and it requires paying attention to other users, learning from them and then using this knowledge to educate other members.
So, if you want to do that, there is no other way than to engage in conversations. I can assure you, that I have been laughed at, at first. But gradually, you prove yourself useful and the whole situation improves significantly.

I am not sture if this information is still correct, but as far as I know bitcoin core does not work as a full node right from downloading it. I thin you have to open some ports in order for other people to connect to your node. This information can however be outdated and best is to simply follow a manual on this.
To run a node, you don't need to open any port. Connections appear to be outgoing or incoming, depending on who initiated them. For example, if we both run a node, then a connection that I have initiated between us, will be outgoing for me and incoming for you, but once the connection is established, it doesn't matter. To allow incoming connections, yes, you must open a port, but this is definitely not an obstacle to run a node. I run a node without even bothered with ports and firewalls. You can also use Tor and allow incoming connections over it, and you will still avoid all the networking hassle. Finally, Bitcoin Core runs as a node instantly. After installing it and setting it to look at a specific location in your storage, then Bitcoin Core will (1) download the blockchain, (2) "talk" to other nodes transmitting information regarding blocks and transactions and (3) verify the validity of new blocks and transactions. |

Here is the distribution of the number of words in the Electrum Wordlist: {'a': 136, 'b': 117, 'c': 186, 'd': 112, 'e': 100, 'f': 106, 'g': 76, 'h': 64, 'i': 55, 'j': 20, 'k': 20, 'l': 76, 'm': 105, 'n': 41, 'o': 55, 'p': 132, 'q': 8, 'r': 108, 's': 250, 't': 121, 'u': 35, 'v': 46, 'w': 69, 'y': 6, 'z': 4}
In the best case scenario, you have 4^12 combinations with all z, and the worst case would be 186^12 with all c. While it isn't impossible, you would have to be quite lucky to be able to find the seeds with that limited amount of information. If you have any other clues other than the first words, you might stand a slightly better chance though I wouldn't exactly count on it. I consider this one to be a very good answer that explains how many combinations exist. I am not aware of any existing program to help you with this endeavor, apart from FinderOuter like BlackHatCoiner said above. However, if we were to write a script to do that, then we would need to check seed phrases' validity, because almost all combinations will not be valid electrum seed phrases. By the way, OP, how did you manage to have a backup were you only have the first letters of the words. I mean, something must have gone terribly wrong. If you knew some of the words, the space of seed phrases would become much smaller and thus the search would be much faster. But you only have the first characters? You must be very unlucky! |

If someone know where to find a list like this till 2019"
.....
Would be really helpfull. Thank you.
Hello. Are you aware of how many wallet softwares exist? Including those that support altcoins, the list is very big and it's obvious that there isn't a list like that, at least not an "official" list. I mean, perhaps you can find a list that some person had written in the past somewhere on a blog or post, but you can't be sure that it includes all the wallets. Anyway, even though I think it's not a good idea to search like that, let me add some possible wallets, you never know... We may get lucky. Please note that some of them, I didn't even know they existed. So I am certainly unaware whether they are good or reputable, or even if they are still operational. Mycelium Wasabi Atomic wallet Coinama Trust wallet Leap wallet Celcius Guarda KeepKey Argent wallet Bitpay Jaxx Crypterium Freewallet Unstoppable wallet Nexo BRD wallet Huobi wallet Token Pocket |
