Czysto teoretycznie, tak. Weryfikacją użytkowników zajmuje się zewnętrzna firma, która na pewno nie jest nieomylna. Co do przydatności Revolut, bardzo podoba mi się opcja zmianu PINu do karty, odblokowywania płatności zbliżeniowych/magnetycznych/internetowych za pomocą jednego kliknięcia w aplikacji. Można nawet zamrozić kartę co prawdopodobnie powoduje, że wszystkie transakcje zostają odrzucone.

Yes, but what's the point of such setup anyway? Your private keys never leave TREZOR (unless there is a major security issue but those are fixed relatively fast and usually require a physical access to the device). By the way, since Trezor T supports SD cards and has a built-in screen, in the future it should support offline signing (no need to use any extra software). Unfortunately, no ETA was provided by the developers on their Telegram channel. I am quite sure I have seen a github commit related to this.

It looks like you have misunderstood me. I am not talking about using multiple TREZOR devices to sign a transaction. TREZOR allows you to create separate accounts which have a different Public Key derived from your Master Public Key. This increases your privacy since it helps you not to mix certain coins, but it's less advanced than Electrum's built-in coin control which can be also used with any TREZOR device. You can generate only up to 20 accounts per passphrase due to performance issues.

The seventh step lacks information on adding any other account than the default one. Each account in the receive tab in TREZOR web interface displays a BIP32 path which needs to be typed in during that step.



Each account in Electrum will be saved in a separate wallet file.

Bardzo możliwe. Revolut stara się, żeby nie posądzili ich o pranie brudnych pieniędzy. Pod koniec grudnia uzyskali europejską licencję bankową.


Handel kryptowalutami jest obecnie dostępny tylko dla osób, które posiadają konto premium (30 zł/msc) lub zaprosiły 3 osoby do korzystania z Revolut. W przyszłości funkcja będzie dostępna dla wszystkich. Z tego co mi wiadomo to nie można wypłacać ani wpłacać BTC.

After a long time, we managed to get it to work about a week ago. Actually, we have no idea how. Zap iOS didn't want to connect even though Zap desktop was working properly. However, we had to change a few things before Zap desktop started working.

Firstly, we forwarded port 10009 in the router settings and added a firewall exception (sudo ufw allow 10009).

A few changes in the config were needed (sudo nano /home/bitcoin/.lnd/lnd.conf). The following lines were added under the [Application Options] section.

tlsextraip=PUBLIC_IP
rpclisten=0.0.0.0:10009
externalip=PUBLIC_IP

After saving the file and rebooting the node, Zap desktop started to work properly while Zap iOS did not. Why? We have no idea. @Zand_ wanted to try another iOS Lightning Network wallet compatible with an external LND instance. 'Union 7' worked for us after the first try. Surprisingly, after setting up 'Union 7' wallet, Zap iOS app also started to work.

Posiadam od kilku dni więc jeżeli będziesz chciał spytać o coś konkretnego to postaram się odpowiedzieć. Wciąż czekam aż dojdzie mi karta (nie musiałem za nią płacić, bo dostałem zaproszenie od znajomego), ale w aplikacji mam już jej dane (CVV, numer, expiry date) i po włączeniu transakcji internetowych mogłem zacząć z niej korzystać. REVOLUT to tak naprawdę jedno konto do którego możesz podpiąć kilka kart (zarówno fizyczne jak i wirtualne, które mogą zmieniać numery po każdej transakcji). W dowolnej chwili możesz otworzyć darmowe konto dla każdej z obsługiwanej walut. Każde konto ma swój unikalny numer IBAN i BIC, które wskazują na to, że rachunek znajduje się w UK.

Warto wspomnieć, że rachunki GBP, NOK, PLN, EUR wspierają 'local transfer' czyli nie trzeba się męczyć z przelewem zagranicznym. Osobiście doładowuję konto poprzez kartę płatniczą. Pieniądze pojawiają się od razu. Niektóre giełdy mogą z jakiegoś powodu odmawiać przekazu na konto REVOLUT. Możesz założyć je poprzez aplikację, otworzyć rachunek w walucie, którą giełda wspiera i spróbować wypłacić. Niestety, ale wcześniej REVOLUT może poprosić Cię o doładowanie 20 zł i zweryfikowanie tożsamości (dowód + zdjęcie), trwa to kilka minut.

That's how it would look like, in my opinion.

DarkStar opens a channel to one of the most well-connected nodes with a maximum amount of BTC per channel (~0.16 BTC). Participants of this campaign interested in receiving payments via the Lightning Network would have to open a channel to that node. Note that before receiving money over the Lightning Network, you have to make space for those incoming funds and that's the biggest issue here. Also, 'Sphinx' is still only a draft so every week users would have to generate an invoice and send it to DarkStar. DarkStar's channel would quickly run out of available funds.

Lightningnetworkstores.com will help you to find a website where you will be able to spend a few satoshis. Check out Yalls, you might find some interesting information there if you pay a small fee via the Lightning Network, of course.

It is also worth to mention that a new draft 'Sphinx' has been published. If both nodes upgrade then it is possible for them to transact with each other without having to generate an invoice. As @pooya87 pointed out, the invoice contains a lot of important information so how does Sphinx work? Detailed explanation can be found here. Sphinx won't be included in the official release anytime soon but using the Lightning Network will become more convenient in the near future.

Some people might be following this thread or might find my answer useful in the future. It turned out that zapconnect was out-of-date and had been replaced with lndconnect. Also, the installation process of Go for Raspberry Pi is a bit different. Note: the following commands are supposed to be used by user 'admin'.

cd /usr/local/ && sudo wget https://dl.google.com/go/go1.11.5.linux-armv6l.tar.gz
sudo tar -xvf go1.11.5.linux-armv6l.tar.gz
echo 'PATH="/usr/local/go/bin:$PATH"' >> ~/.profile - reconnect after typing in this command

Now, it's time to build lndconnect and use it to generate the QR code needed in the Zap iOS app.

cd ~ && go get -d github.com/LN-Zap/lndconnect
cd /home/admin/src/github.com/LN-Zap/lndconnect
make
cd ~/go/bin
./lndconnect —adminmacaroonpath=/home/bitcoin/.lnd/data/chain/bitcoin/mainnet/admin.macaroon —lnddir=/home/bitcoin/.lnd/ --configfile=/home/bitcoin/.lnd/lnd.conf -j

This command should return a text which needs to be converted to a QR code. This website seems to be a fairly good one to do that.

Right now, we are facing the 'Can't connect to server' error. However, I have just provided @Zand_ a possible solution (related to LND config; port forwarding and ufw rules have been changed correctly). I will add another post once he confirms if my suggestion has worked.

I don't think if there is any Android Ethereum wallet which supports Ledger Nano S. The only app worth taking look at, in my opinion, is WallETH if you are using an Android device. Unfortunately, it looks like it supports only TREZOR devices.

Yes, it is a normal behavior of every TREZOR device. You can easily check it by connecting your TREZOR to your phone charger. The device automatically boots up after it receives power. For example, TREZOR T does not establish a USB connection (no data is sent to the PC) if user doesn't enter the PIN on the device. TREZOR One has to communicate with the PC right after establishing a connection because it is needed for PIN entry.

Dzięki @cryptovigi za podsumowanie minionego roku! Muszę przyznać, że w grudniu i styczniu miałem trochę rzeczy na głowie i raczej prędko się to nie zmieni. Prawo jazdy już jest, ale matura już za niedługo Obecnie mam do dyspozycji 92 sMeritów, a mimo to trochę powstrzymuję się od ich rozdawania, bo obawiam się, że szybko mi się one skończą, a podania na merit source nie złożę dopóki nie pozbędę się większości. Błędne koło, czyż nie? Myślę, że i tak jesteśmy na dobrej drodze. Wystarczy spojrzeć na ten temat. W bardzo krótkim czasie wypowiedziało się kilka osób i wywiązała się z tego mała dyskusja.

Przejrzę dzisiaj wieczorem dokładne warunki aplikacji na merit source i jeżeli uznam, że je spełniam to przygotuję podanie. Dam Wam znać w tym temacie.

Ethereum mining requires at least 3 GB of VRAM due to constantly growing DAG size. Unfortunately, you won't be able to mine Ethereum with those two cards. I haven't used the new NiceHash app but the older one allowed user to choose algorithm. You should be able to mine something else.

TREZOR partnered with GRAY and created a new brand Corazon - a limited edition of devices built on Trezor Model T is available for pre-order. The cheapest model costs $942 SGD (~$695 USD) and the most expensive one which is limited to 100 pieces costs $2028 SGD (~$1500 USD). The only difference is that these devices are made of titanium. Functionality remains the same. More information can be found here.

Yes, I do. You have to set up port forwarding on your router (this includes assigning fixed internal IP to your Raspberry Pi and then forwarding port 22 (SSH) to that IP). However, it depends on your ISP whether or not it is possible and the whole process looks different on each device. I can help you set it up but you might have to disclose some sensitive information so I would recommend you to contact me on Telegram or send me a private message/an e-mail. You might find a tutorial on-line for your router, though.

No, that will probably break something. We have to get rid of everything related to Go. Remove the following lines and save the file.


Now, you can use echo 'PATH="$PATH:/usr/local/go/bin"' >> ~/.profile. Log out and try to use the command from Zap connect.

Okay, I have just tested it on my VPS and we have to do one more thing.

cd ~ && nano .profile - I assume that you have nano installed. If not then run sudo apt-get install nano

There is probably a lot of mess there. Delete everything EXCEPT the code below


Press CTRL+O at the same time and then enter to save the file. Press CTRL+X to leave the editor.

echo 'PATH="$PATH:/usr/local/go/bin"' >> ~/.profile - Log out after this command and try using the command from Zap connect

By the way, does snap command work for you? I am running Ubuntu 18.04 on my VPS and it suggested using sudo snap install go -classic (it would download the latest version). Give it a try if the rest doesn't work!


It proves that the package was out-of-date (1.7.4 was released at the end of 2016!).

It won't happen automatically since these folders were created manually by you. You don't have to change anything. Let's keep these folders with 777 permissions for now. By the way, is there anything beside LND that you run on your Raspberry Pi?

I am afraid that the package (golang) is a bit out-of-date (it's a common thing, unfortunately). Can you tell me which version of Go is currently installed? (go version) If it's lower than 1.11.1 then we will have to proceed with the manual installation again. Try the following commands anyway.

sudo apt-get remove golang* - '*' is necessary
sudo apt-get autoremove
sudo rm -r /usr/local/go - just in case you accidentally moved the old version

Now, after typing in go version you should see 'Unknown command error'.

cd /usr/local/ && sudo wget https://dl.google.com/go/go1.11.4.linux-armv6l.tar.gz - not the 32 bit version as I recommended earlier but the ARM one
sudo tar -xvf go1.11.4.linux-armv6l.tar.gz
sudo rm go1.11.4.linux-armv6l.tar.gz - let's keep things clean

The $GOPATH should not change but let's make sure that it will work properly. Don't forget to log out after using the commands below.

export GOROOT=/usr/local/go
echo 'export GOPATH=$HOME/go' >> ~/.profile
echo 'PATH="$HOME/go/bin:$PATH"' >> ~/.profile

Run go version and you should see go version g1.11.4 linux/arm. Run the command from Zap connect.


I fell asleep immediately after making my previous post. Thank you for your generous tip! Now I am considering buying a Raspberry Pi for myself
