Okay, that's great. For some reason permissions are not working properly so we will have to do it in a bit insecure way. Use sudo chmod -R 777 ~/go (this will allow every single user to modify the contents of folders and files inside go) and then run go get -d github.com/LN-Zap/zapconnect. I am too sleepy to think of a better solution.

Try running that command without sudo. Also, check what has happened to $GOPATH by typing in go env. If it has changed then use the previous two echo commands to set it again.

It looks like Go requires three more folders to work. Use sudo mkdir ~/go/bin ~/go/src ~/go/pkg. You can also run all the commands from Zap connect with sudo in the beginning just in case.

Some of the environment variables must be different in this case. Try the following commands

sudo mdkir ~/go
echo 'export GOPATH=$HOME/go' >> ~/.profile
echo 'PATH="$HOME/go/bin:$PATH"' >> ~/.profile

Log out, connect again to your machine and then run go env to see whether or not GOPATH has changed. If so, try the command from Zap connect.

I guess that you needn't have looked at the environment variables (go env) since it was installed in a different way. You should have moved on to the Zap connect part. Let's try to fix that. Type in the following commands.

sudo rm -r /usr/local/go - to make sure that the folder you have moved is completely deleted
sudo apt-get remove golang - completely getting rid of everything related to the Go. I don't think that purge command is necessary here.
sudo apt-get install golang

Please, let me know if this has worked for you. I am going to bed soon.

Edit: Oh, you have just changed your post. I will answer it in a moment.

Miałem kiedyś Ledgera Nano S, ale sprzedałem go, bo miałem dość problemów z ich dodatkiem Chrome. Altcoiny to nie pokemony dla mnie więc nie muszę mieć ich wszystkich. Nano X jest ciekawy ze względu na większy ekran i możliwość komunikacji przez Bluetooth. Idealne rozwiązanie dla ludzi, którzy chcą mieć przy sobie trochę BTC na telefonie do wydania, ale i tak boją się skorzystać z portfeli mobilnych, które oferują całkiem przyzwoite bezpieczeństwo.


Producent zapewnia, że niemożliwym będzie wyciągnięcie prywatnych kluczy poprzez Bluetooth - po to w urządzeniu znajduje się tzw. Secure Element. Ciekawe jak długo urządzenie wytrzyma ataki. Ostatnio Nano S został pokonany przez małą antenkę w środku.

Cena pozytywnie mnie zaskoczyła. Spodziewałem się co najmniej 150 euro za sztukę. Kupiłbym, ale posiadam już Trezora T oraz Trezora One. Może jest ktoś chętny do odkupienia Trezora One ode mnie? Wtedy zastanowię się nad zakupem nowego Ledgera

Log in to your blockchain.info account and click on the 'Security Center' on the bottom-left of the page. You should be able to backup your recovery phrase there. Download Electrum and follow this guide in order to import your wallet. Please note that importing a wallet is not the same as sweeping. If you want your funds to be completely safe then create a new wallet, write down your seed properly and send your funds from the imported wallet to the new one.

How long has it been since you received those coins? Aren't they just unconfirmed? You might be forced to wait 6 confirmations before you will be able to spend them.

sudo apt-get install golang automatically installs Go and other dependencies in case they are needed on your system. I wonder why it isn't mentioned in the tutorial. There is a slight chance that the repository won't be available for your OS (I can't recall which version it was) and the whole installation will fail. If you don't want to play around with the 32 bit version then you can try using this command first.

In this case, it means that you have to get rid of the version that you have currently installed. You can do it easily by typing in sudo rm -r /usr/local/go because you have installed it manually. If you get 'Unknown directory error' or something similar then you must have done something wrong in the first place. Don't forget about the second suggestion if the first one doesn't work for you.

There are two things that I would try if I were you:

1) Download the 32 bit version of Go instead of the 64 bit one. https://dl.google.com/go/go1.11.4.linux-386.tar.gz

2) If the first suggestion doesn't work then use the following command sudo apt-get install golang

Don't forget to revert everything you have done so far before trying out each of these.

There aren't many articles on Sphinx since the commit was created 4 days ago. Lightning Network invoices contain a lot of important information which is required for sending a payment (destination, payment hash, number of satoshis, expiry, timestamp and cltv expiry). In Spinx, invoices are replaced with the EOB which allows to encode extra data for the receiver. That is what I managed to conclude from the available information. Please, correct me if I am wrong. I will continue my research tomorrow.

Try installing Go automatically by typing in sudo apt-get install golang. You must have done something wrong during the manual installation.

Edit:


Ah, you shouldn't have skipped that much. The skipped part describes the installation process of LND and Go which is necessary.

There is no detailed article on public keys on the Bitcoin Wiki, but you can learn about public key cryptography from this Wikipedia entry.

Haven't they just introduced Discord Nitro gifting? HypeSquad members were given free Discord Nitro gift on the 20th December so that they could test out this feature. Bitefill introduced Steam gifts after Steam removed BitPay payments.

Edit: @TryNinja I am aware of that. My point is that gifting has just been introduced and Bitrefill didn't have much time to introduce it.

Are sure about that? I am quite sure that I managed to get it to work by simply using USB to micro-usb converter provided by Samsung with the original cable. The same goes for Trezor. It works perfectly fine.


Ledger claims that data sent over Bluetooth is end-to-end encrypted. What about man-in-the-middle attacks?

Bitomaty głównie trafiają do ruchliwych miejsc (najczęsciej do centrów handlowych), które są objęte monitoringiem. Nie mam pojęcia czy każdy bitomat posiada swoją własną kamerę. Część z nich na pewno ją ma do zeskanowania kodu QR zawierającego adres BTC osoby chcącej zakupić monety. Wątpię żeby ktokolwiek stał przy nich przez cały dzień i wyszukiwał sobie potencjalne cele. Jeżeli nie chcesz, żeby bitomat wiedział ile tak naprawdę monet znajduje się na twoim adresie to możesz skorzystać z mikserów monet.

Some of my transactions would not show up or it would take ages for the Chrome app to load (certainly not because of my PC). I was aware of Ledger support in Electrum but I was disappointed with the provided software.


Carrying a separate phone only for Ledger would be pretty inconvenient. For how long have you had your Ledger Nano S?

Honestly, 119 euro isn't really that much. I thought it would be somewhere around 150 euro. I bought my Ledger Nano S for 100 euro but I quickly got tired of missing transactions (due to enormous load on Ledger servers back then) and decided to sell it to a friend. Has anyone pre-ordered it yet? How does Ledger Live work in comparison to the deprecated Chrome app? Does it perform better?


Fortunately, Ledger mobile app will be also compatible with older models (Ledger Nano S and Blue). Source:

Eclair (Android) has been renamed to Eclair Mobile and received an update. User is now able to select to which Electrum server he wants to connect to. Receiving LN payments will be enabled somewhere in 2019 after LN 1.1 goes live (dual-funding and liquidity advertisement is needed). More information can be found in this article.

Exactly. Keep in mind that you can't broadcast signed transaction on the offline computer so you have to move it to the other computer.


Are you sure that your Bitcoin Core synchronizes correctly with the network? I am quite sure that there was a command which allowed you to check if your private key is related to a certain Bitcoin address. I can't recall it right now. Did you use your public key to create the watch only wallet?
