As long as you make sure not to reuse old addresses with the new ones in the same transaction, the observer won't be able to tell if the balance of the wallet "A" has changed.

"To open a channel" means the same as "to fund a channel". Making space for the incoming funds is a different thing. By the way, if someone opened a channel with you, you wouldn't need to spend any coins in order to receive because the coins would be on the other party's side of the channel.


Yes. You also should pay attention to how well those nodes are connected to the rest of the network. The more channels they have, the more likely your payment is to succeed. Also, c-lightning can split large payments into smaller ones and send them through different routes. Electrum can't do that.

Once you are able to claim your reward, the game will ask you to provide a payment invoice. Both Electrum and your c-lightning node are able to generate it. As I mentioned earlier, first, you have to open a channel with some other node and spend some coins so that you can receive (check out the FAQ for explanation). This node belongs to the developer of the game. You can also choose a node from here; it's sorted by the channel count.


That's fine. We have already answered plenty of such questions there.

What game are you referring to? I should be able to tell you if it's going to work if you tell me its name.


Feel free to ask those questions in the Lightning Network FAQ thread. Quite a few people watch that topic.

If that's the case then you can use Electrum without installing any additional software. I thought that you necessarily wanted to use your c-lightning node. I wrote a walkthrough of Lighting Network support in Electrum. You might find it useful.


You can use your Lightning Network node to receive payments but you need to open a channel first with some well-connected node (or directly with the game's node) and make room for the incoming funds by spending some coins over the LN. The same applies to Electrum which might be easier for you to use. You seem to be a bit confused about how the Lightning Network works.


I am currently rewriting the "Basics of The Lightning Network" thread but it should still be helpful.

If you want to manage your node using Electrum then it is not possible. Lightning Network support in Electrum is a standalone implementation written in Python. Spark Wallet can connect to a c-lightning node and provide basic functionality (channel management, sending and receiving payments). It is available for Windows, Linux, Mac and Android.

If you want to open a channel with your node then you need your node's id and IP address. Keep in mind that all of your payments will fail if you don't have any open channels with other people on your c-lightning node.

Why would you do that in the first place? The probability of generating an already used seed is extremely low.


If you don't intend to use those wallets then you can restore those seeds in Electrum.


Yes, you would need to enter your last seed again after testing both seeds.


Yes, there would be no entries in the "History" tab (in Electrum). It is impossible to tell when the seed was generated. It will be more convenient for you to do it in Electrum. The result will be the same.

To zależy od tego jak często przeciętny użytkownik PC będzie w ogóle miał styczność z Bitcoinem Nie oszukujmy się, że przeciętny zjadacz chleba będzie używał oprogramowania podobnego do Bitcoin Core czy Electrum, zwłaszcza jeżeli mówimy o codziennych wydatkach. BlueWallet jest dobrym przykładem kierunku, w którym zmierzamy. Użytkownik ma pełną kontrolę nad swoimi środkami, ale w momencie kiedy chce skorzystać z Lightning Network, to zamiast otworzyć nowy kanał, użytkownik przesyła swoje środki na adres należący do właściciela już istniejącego HUBu, który będzie obsługiwał wszystkie przychodzące i wychodzące płatności. Ten wpis opisuje to bardziej szczegółowo.

Takie rozwiązanie na pewno nie wszystkim się podoba, ale osobiście uważam, że było to nieuniknione. Dobrze, że tak wcześnie pojawiają się alternatywy dla osób, które są mało techniczne. Za parę lat możemy dojść do etapu, gdzie przykładowo użytkownicy Coinbase będą mogli płacić poprzez Lightning Network nie wiedząc, że coś takiego istnieje.

You can either close the channel and open a new one or use refill services which I described above.


If the remaining balance is lower than the dust limit (546 sat) then those sats are added to the closing transaction fee.

The maximum channel size is about 0.167 BTC. However, some implementations already allow node operators to lift this limitation so that they can open as big channels as they want.


You cannot increase the size of the channel after you fund it. It is called splicing-in but this feature is not available yet. You can use third-party services to "refill" your channel. Electrum has such a functionality built-in. Those services simply send coins over the Lightning Network to one of your channels so that the funds locked up in the channel shift back to your side from the other party's side.

Well, that depends. You could have paid a smaller fee and waited longer or opened a channel when the fees were much lower.

There is no point in opening a channel if you intend to make few transactions. If you opened a 20 mBTC channel with the same fee and sent a dozen of transactions, it would be cost-effective.

No, it wasn't. 1.5 mBTC is 150000 sat which is still less than 200000 sat required by Electrum. Your channel should become active after 3 confirmations.

That's not possible. I have just tried opening a 2 mBTC channel with microlancer and I was asked to sign the funding transaction. Are you sure that you put 02bb10aaa77a95a358cebb2d112c4de00e47c08f56e89b1acb4487ddd44cc98d6d in the "Remote Node ID"?

If you don't intend to use the native SegWit account then you can uncheck it and select "Add account". Leave "Bitcoin 1 (segwit)" checked.


You didn't have a legacy account so there is nothing to worry about.

That's correct.


The order in which you delete those accounts does not matter.

The minimum funding value for all channels is 0.002 BTC (Electrum limitation). You need to pay for an on-chain transaction in order to open a channel. If you open a direct channel with microlancer then all Lightning payments to them will be feeless. Note that you will not be able to spend your whole channel's balance. You can learn more about Lightning Network support in Electrum from this thread.

It's neither an address nor an invoice. It's a node id which points to microlancer.io's Lightning Network node. You need to get a payment invoice from them if you want to pay them over the Lightning Network. Do you have any open channels?
