1  Local / Tablica ogłoszeń / Sprzedam nowego Ledgera Nano X on: August 01, 2019, 07:55:50 PM
Cześć,

czy ktoś z tu obecnych byłby zainteresowany kupnem Trezora T? Zastanawiam się nad zmianą na Ledgera X, gdyż będę potrzebował mniejszego urządzenia, które z łatwością będę mógł używać poza domem. Pre-order złożyłem pod koniec 2017 i urządzenie otrzymałem na przełomie lutego i marca 2018 roku. Zainteresowanym mogę przesłać zdjęcia, urządzenie jest w dobrym stanie.
2  Bitcoin / Hardware wallets / Ledger Live now supports Bech32 addresses! on: July 17, 2019, 02:54:43 PM
Ledger has just released a new update in which support for native SegWit addresses has been introduced.

What are the benefits of using such addresses?

- lower transaction size,
- smaller QR code,
- case-insensitivity.

Note that some services might not be able to send to native SegWit addresses. If you need full compatibility and still want to save some money on fees then use nested SegWit addresses (they start from 3).

General Information

How are bitcoins on the Lightning Network different from on-chain bitcoins?

They are exactly the same coins. There are no Lightning Network tokens. The only difference is that bitcoins are stored in multi-signature addresses and transactions are settled between two parties without broadcasting anything to the blockchain (except when opening and closing the channel).


When will merchants start accepting Lightning Network payments?

More and more merchants start accepting Lightning Network payments. The most popular payment gateaway - BitPay does not accept Lightning Network payments and is very unlike to introduce them anytime soon. Here you can find a list of merchants who accept LN payments.


How many times can we expect to be able to use a payment channel?

Every channel has a minimum amount of coins which has to stay unspent. Channels can be used as long as both parties continue to cooperate with each other.


How fast and reliable are Lightning Network payments?

Depending on the route, Lightning Network payments can be instant. Every wallet tries to find the cheapest and the shortest route once you send your transaction. You can open a channel directly to a person who you are going to often trade with or depend on other channels which might route your payment for a small fee. Lightning Network is still in its early state so payments fail from time to time.


What are the upcoming features?

Dual funded channels - both parties will be able to fund a channel.

Watchtowers - they will be responsible for taking care of people attempting to cheat while the other party is offline. Added in LND v0.7.0

Muilti-path payments - currently, the payment can't be divided into smaller ones which sometimes results in failed payments due to not enough funds in the channels.

Sphinx - users will be able to send payments without having to ask the other person to generate an invoice.

You can find more here.


Where can I find the latest news regarding the Lightning Network?

Telegram channel - a whole group of knowledgeable people ready to talk about the Lightning Network. Great source of information.

Bitcoin Lightning - a website strictly focused only on the Lightning Network.

Cointelegraph - nothing to add here.


Which wallet is the best one?

There are multiple implementations of the Lightning Network and most wallets have similar features. However, some mobile wallets can't receive payments. Eclair Mobile is the most popular wallet for Android but it is also available on Windows. The most popular implementations are: c-lightning, LND and eclair mentioned earlier.


Running a node

How much money can you make on running a Lightning Network node?

In order to start making money on running a node, you have to open a few channels. Keep in mind that built-in autopilot might not guarantee you the best connections. Don’t expect to make a lot of money. Everything depends on the number of connections and your fee policy. The less you charge, the higher your chances to route a payment. Don’t set the fee too low. You have to save up money for future channel re-balancing. User Xian01 opened almost 200 channels and earned barely 15 satoshis after 2 weeks (Reference).


How do channel owners get paid for routing payments?

Fees earned from routing payments are added to the balance of the channel. The total fee charged is basefee + (amount * feerate / 1000000), where amount is the forwarded amount. If you set both of these values too high, you won't route any payments.


Is running a Lightning Network node demanding?

You can run a Lightning Network node on both Linux and Windows. If you choose any other implementation than LND then you have to run a Bitcoin full node which uses the biggest part of available resources. Even Raspberry Pi 3 B+ is capable of running a Lightning Network node. Check out RaspiBlitz for fast setup.


Is there any risk in running a Lightning Network node?

Yes, due to many factors. Lightning Network implementations are still in beta and might contain critical bugs which could be used to steal funds locked up in channels. Keep in mind that if you won't keep your node online 24/7, someone can attempt to cheat you by broadcasting an old state of your channel. An online node would normally broadcast a penalty transaction.


Does opening new channels help to increase the earnings?

No, it doesn't. There are many other things that you should take into account. Your fee policy, channels' capacity, connection to different sized nodes. Here you can find an interesting comparison between Andreas Brekken's and Alex Bosworth's nodes. The node which had lower principal, made higher profit.


Do I have to run a full Bitcoin node?

As long as you decide to use LND which supports neutrino, you don't have to run a full node. It allows user to run a lightweight node instead of a full one. It is a good solution for devices with low processing power and storage (Raspberry Pi). Other implementations do not support that feature at the moment.


How do I set up a Lightning Network node?

The setup process varies for each implementation. Fortunately, detailed documentation makes it easy for inexperienced users to start their own Lightning Network node even on Linux. If you don't feel confident with any other operating system than Windows then take a look at this tutorial which will help to set up your own node.


What is the purpose of setting alias and color?

This information is often used by Lightning Network visualisers and explorers. It is not very important and has no impact on how the node works.


Do I have to generate an invoice every time I want someone to send me coins over the Lightning Network?

Currently, in order to receive a payment over the Lightning Network, a single-use invoice has to be generated. However, Sphinx will allow users to send payments without having to request the invoice from the other person. Sphinx can be already used if both nodes update to the test branch.


Can I refill my channel?

Currently, there is no way to refill channels without using third party services such as Lightning Conductor. Splicing will allow users to either top-up their channels or drain funds from them without having to reopen the channel. Channel balance will be updated once the transaction gets enough confirmations.


Why can't I receive coins?

In order to receive Lightning payments, some conditions must be met:

1. Nothing can be received immediately after creating a new payment channel, as ‘room’ for incoming funds has to be made by spending some funds first. A payment channel can be thought of as a full bottle of water: in order to pour something in one first has to pour something out.

2. Each channel implicitly contains a reserve which is unspendable and typically takes about 2% of the channel’s capacity. You must spend an amount matching that reserve to make receiving possible. Unspendable channel reserve is the reason you see a negative receive limit when a new channel is full. It indicates how much you need to spend before anything can be received through the channel.

3. Every payment request is disposable, they can’t be fulfilled twice. So you will need to issue a new individual payment request for every incoming payment you wish to receive.

4. Wallet needs to be online in order to receive off-chain funds.

Note that not every mobile wallet supports receiving coins because of the fourth point. There are some exceptions such as Bitcoin Lightning Wallet (Android), Eclair Mobile (Android).


What happens if a funding transaction doesn't confirm in time?



Concerns

Is Lightning Network centralized? Is it more centralized than Bitcoin? Does it make Bitcoin more centralized?

This topic has been brought up many times. The Lightning Network is a second layer scaling solution which has no impact on the Bitcoin network. It works independently and no one is forced to use it. The problem of large nodes should solve itself once network continues to grow.


Will casual users be able to accept payments and donations without having to run their own full node 24/7?

Both OpenNode (payment gateway) and Bitlum.io allow users to receive Lightning Network payments without having to run a full node. However, these wallets are custodial which means that they have a full control of one's funds.


What are the new limitations of scalability once lightning is fully functional?

Opening and closing a channel requires broadcasting a Bitcoin on-chain transaction. Increasing the blocksize might be necessary in the future; however, solutions like SegWit, Schnorr signatures can help to decrease the size of transactions. Lightning Network is a second layer protocol, it is possible to build more user-friendly layers on top of it.


What would happen if a large node disappeared from the network?

Recently, we were able to observe Andreas Brekken’s experiment (shitcoin.com node). He was in charge of a node whose capacity was around 43 BTC (more than 50% of the whole network’s capacity!). After its closure, some people started to experience routing problems.


Is Lightning Network more anonymous than on-chain transactions?

Lightning Network increases the level of privacy. The next node doesn’t know if the previous one initiated the transaction. Every node which routes the payment doesn’t know the details of the transaction (final destination, sender).


What happens if some nodes go temporarily offline?

The problem of "zombie nodes" hasn't been solved yet. Offline channels are still considered as capable of routing payments which in some cases cause the payment to fail because channels are unavailable. It is a matter of making a few changes to how channels signalize their state. More information can be found here.

This problem has been addressed in the v0.5 release of LND. When a channel is being closed or a peer node has gone offline, the rest of the network is informed that they are incapable of routing payments. It is also possible to create unadvertised channels which won't route payments.

This thread is now self-moderated. Old thread got derailed. Please, don't discuss here whether or not the Lightning Network is a good scaling solution.

5  Bitcoin / Wallet software / Lightning Labs Lightning Network wallet on: June 19, 2019, 10:19:34 PM
Lightning Labs has released a new non-custodial Lightning Network wallet for both iOS and Android. The wallet is powered by LND and neutrino which allows to verify Bitcoin transactions without having to run a full Bitcoin node. Interestingly, it supports autopilot but lacks many features that other wallets have. It's still in alpha, though. More information can be found here.
6  Bitcoin / Bitcoin Wallet for Android / Zap (Android) has been released! on: June 19, 2019, 09:43:53 AM
A few days ago, Zap for Android was published. Currently, it only allows user to manage funds and see the channels of an external LND node. iOS version has way more features but that's because the Android version has been developed by a different user who did it voluntarily. Full story can be read here.

This wallet is currently useful only to those who are running a LND node. Creation of payment requests is much easier with it. lndconnect is required on the node.
7  Other / Meta / Lightning Network board on: June 05, 2019, 08:46:41 PM
Lightning Network's popularity has been growing for some time now. More and more threads will be created about it due to growing interest in new scaling solutions. My suggestion is to create a separate board dedicated to the Lightning Network. This will make finding information on it easier for some people.

The Polish section certainly lacks an active merit source. Our moderator and the only merit source malevolent hasn't been really active in the past few months. He cleaned up our section a bit a few days ago.

There are a few active posters in the Polish section who are doing their best to encourage new users to create new threads and posts in our section instead of using a forum dedicated to the Polish community. I am constantly trying to reward them for their hard work with merit. It might surprise most of you, but, currently, I have exactly 113 sMerit available to spend. Why do I even bother to submit an application? Well, I am trying to save up as much merit as possible so that I could reward people for more sophisticated tasks. Unfortunately, because of this I tend not to reward some posts and wait for others to do so. I wrote a few tutorials and asked if there was anyone interested in translating them for merit. The results are listed below:

Other members did a great job by meriting existing threads but almost all of them have run out of merit and they won't earn it anytime soon since they post a lot in our local board in order to make it more lively.

I have also selected a few posts which deserve more merit in my opinion. Most of them are quite long so I decided to post links instead of quoting them.

10  Bitcoin / Project Development / LNchat.org - dedicated LN community site with various built-in LN functionality on: February 18, 2019, 11:02:46 PM

I would like to present you an idea with which I and Zand_ came up while we were solving his Lightning Network node problems. We would like to create a place where people could easily discuss Lightning Network related problems and projects. Some tutorials are out-of-date which makes it even more difficult to start using the Lightning Network. We would like to fix that by rewriting and keeping them in one place. I have already made two long threads on bitcointalk (Basics of the Lightning Network and The Lightning Network FAQ) which I believe helped quite a few people to understand what it is all about.

We would like to encourage people to use the Lightning Network by introducing a small fee for adding a new thread or post. There would be a section excluded from this rule for inexperienced users where they could describe a problem which makes it impossible for them to pay the fee. We would like to implement a system similar to the merit on bitcointalk. It would be great to see people thanking each other by sending a few satoshis. We are aware that some people won't be able to generate the invoice at specific time so we will handle it instead and pay out the reward on demand.

We would appreciate if you could answer a couple of our questions.

1) Which forum software would you prefer? Invision Community or Discourse?

2) Do you like the idea of paying a small fee (e.g. 1 satoshi) for making a post?

3) What do you think is an appropriate cost for posting a thread vs a comment?

4) What other functionality would you like to see in the site?

5) What features do you think could be added to further incentivize use of the site?

6) Which name do you prefer? lnchat.org or lightningchat.org? Both domains have been already bought by us

12  Local / Polski / Jak otrzymywać powiadomienia o zacytowaniu wypowiedzi lub @wspomnieniu? on: November 28, 2018, 08:27:38 PM
STATUS: DZIAŁA

Skrócona wersja:
Możesz wypróbować nowy system powiadomień poprzez wysłanie prywatnej wiadomości do Maggiordomo zatytułowaną subscribe wraz z linkiem do twojego tematu (najlepiej stworzonego w dziale Archival), który będzie używany przez bota do informowania ciebie o wzmiankach oraz zacytowaniu twojej wiadomości. Jeżeli zrobisz wszystko poprawnie to otrzymasz wiadomość z podstawowymi informacjami o bocie.
Kiedy ktoś napisze @twojaNazwaUzytkownika lub @twoja=NazwaUzytkownika (jeżeli twoja nazwa użytkownika zawiera spację to musi zostać zastąpiona przez = ) otrzymasz jedno lub więcej powiadomień w swoim temacie.

Przeczytaj sekcję komendy aby dowiedzieć się co jeszcze możesz zrobić.
Przeczytaj sekcję telegram aby dowiedzieć się jak otrzymywać powiadomienia poprzez telegram.



Co wywołuje powiadomienie? (cudzysłów " jest po to, aby ułatwić zauważenie spacji):
Quote
" @użytkownik "
Quote
" @użytkownik* "
gdzie * jest dowolnym znakiem. Powinno to uniknąć sytuacji gdzie "," "." "?" oraz inne znaki powodowały brak powiadomień.

Jeżeli @nazwaUżytkownika znajduje się na początku lub na końcu wiadomości to po niej musi dodatkowo zostać umieszczona spacja.

Quote
"@użytkownik jak się miewasz?"
Quote
"cześć jesteś @użytkownik " 
Quote
"cześć @użytkownik
jak się masz?"

Przykłady poprawnego wspomnienia:

@asche! @actmyname? @Loyce( test ) @babo.

Te nie zadziałają:

@Halab?, @TomCrypto... @Piggy(test)



Dłuższa wersja:
Pierwszą z zaplanowanych funkcji bota jest powiadamianie użytkownik o tym, że ktoś o nich wspomniał bądź zacytował ich post. W tej chwili ta funkcjonalność działa poprawnie, a nowe będą powoli dodawane. Potrzebna jest większa ilość użytkowników do przetestowania czy bot będzie działał poprawnie przez dłuższy czas.

Jak działają powiadomienia?

Jeżeli poprawnie powiążesz swoje konto z botem to otrzymasz powiadomienie jeżeli ktoś:
  • Napisze @TwojaNazwaUżytkownika lub @Twoja=NazwaUżytkownika (znak "=" powinien zostać użyty tylko w wypadku gdy twoja nazwa użytkownika zawiera spację)
  • nowe: Bezpośrednio zacytuje twój post
  • nowe: Napisze twoją nazwę użytkownika bez @


Zostaniesz powiadomiony przez użytkownika Maggiordomo. Otrzymasz jeden lub więcej linków oraz częściowy cytat postu, w którym zostałeś wspomniany.

W przyszłości pojawi się więcej opcji modyfikacji treści powiadomień oraz ich całkowitego włączania/wyłączania.

Jeżeli nie zarejestrujesz się to nie będziesz otrzymywał powiadomień od bota.

Jak komunikować się z botem i co on robi?

Zanim będziesz mógł otrzymywać powiadomienia od bota to musisz stworzyć swój własny temat (najlepiej w sekcji Archival), w którym bot będzie mógł dodawać posty. Jeżeli chcesz otrzymywać wiadomości poprzez Telegram to nie musisz tworzyć takiego tematu. Sposób postępowania został opisany poniżej.

Komendy:
  • Aby się zarejestrować: wyślij wiadomość do użytkownika Maggiordomo zatytułowaną subscribe wraz z linkiem do twojego tematu w treści. Otrzymasz wiadomość o poprawnym zarejestrowaniu się wraz z podstawowymi informacjami. Jeżeli chcesz otrzymywać powiadomienia poprzez Telegram to spójrz niżej.
  • Aby zrezygnować z otrzymywania powiadomień: wyślij wiadomość do użytkownika Maggiordomo zatytułowaną unsubscribe i wpisz cokolwiek w treści wiadomości aby móc ją wysłać

NOWOŚĆ:
Wysyłając wiadomość zatytułowaną subscribe lub options (jeżeli już subskrybujesz) to w treści wiadomości możesz użyć następujących parametrów:

Code:
alias:twój_alias
https://bitcointalk.org/index.php?topic=00000000
tagusername:on
quote:off
plainusername:on
automention:off

odpowiednio:

Alias inna nazwa, która będzie wywoływać powiadomienie bez lub z @ w zależności od poniższych ustawień
Twój temat w tym miejscu bot będzie dodawał posty dotyczące twojego konta
Tagusername, włącz/wyłącz powiadomienie gdy ktoś użyje @ do wspomnienia ciebie
Quote, włącz/wyłącz powiadomienie o zacytowanie twojego posta
Plainusername,  włącz/wyłącz powiadomienie gdy ktoś napisze twój nick bez @
Automention,  włącz/wyłącz powiadomienie gdy sam wspomnisz o sobie
notifyby,  wybierz gdzie chcesz otrzymywać powiadomienia (forum/telegram/oba)

Wszystkie opcje powyżej są domyślnie włączone za wyjątkiem aliasu, który musi być ustawiony ręcznie.

Nie będziesz mógł otrzymywać powiadomień jeżeli ktoś inny używa tego samego aliasu.

NOWOŚĆ
Powiadomienia poprzez Telegram

Ważne:

Przed albo po rejestracji skontaktuj się z @Maggiordomo_Service_bot poprzez telegram z tego samego konta, które podałeś podczas rejestracji. Napisz dowolną wiadomość aby powiązać oba konta.

Jeżeli korzystałeś już z bota to wyślij wiadomość zatytułowaną options o treści:

Code:
telegram:NazwaUżytkownikaTelegram

Jeżeli jeszcze nie korzystałeś z bota, a chcesz otrzymywać powiadomienia tylko poprzez Telegram to wyślij wiadomość zatytułowaną subscribe o treści:
Code:
telegram:NazwaUżytkownikaTelegram

Lista użytkowników, którzy otrzymują powiadomienia od bota znajduje się tutaj: https://bitcointalk.org/index.php?topic=5023605.msg45324744#msg45324744

Uwagi:
Musisz być autorem tematu, aby bot mógł dodawać do niego posty (powiadomienia).
Jeżeli zacytujesz post, który zawiera @JakiśUżytkownik to ten użytkownik nie otrzyma powiadomienia.
Możesz wspomnieć kilkoro użytkowników na raz: @Użytkownik1 @Użytkownik2 @Użytkownik3 ...

W tym momencie bot ma rangę Jr. Member więc obowiązują go ograniczenia związane z tą rangą. Musi odczekać około 8 sekund pomiędzy postami więc jeżeli dostaniesz więcej niż jedno powiadomienie to będą one stopniowo dodawane.


Ograniczenia i pomysły:
  • Temat, w którym są dodawane powiadomienia nie może być ogłoszeniem ani bounty w celu zapobiegnięcia "odświeżaniu" tematu.
  • W przyszłości aby otrzymywać powiadomienia od bota to będzie trzeba zdobyć kilka meritów

Przypadki użycia:
  • zachowanie na przyszłość jakiegoś posta lub tematu
  • wskazanie posta, który powinien zostać nagrodzony meritem
  • zwrócenie czyjejś uwagi na konkretny post/temat

Uwaga:
Czasami bot może być wyłączony przez co możesz nie otrzymać powiadomienia na czas lub w ogóle.

13  Bitcoin / Hardware wallets / Trezor T now supports Monero, Ripple and more! on: October 29, 2018, 04:30:43 PM
TREZOR has released a new update for their latest Trezor T which brings support for a few cryptocurrencies such as Monero, Ripple, Stellar, Cardano, Tezos, Decread, Zencash and Groestlcoin. Zcash Sapling hardfork is also supported. Monero is not available neither in the web wallet (privacy concerns) nor in the Monero GUI (it's a matter of time in this case). Currently, it can be accessed only through the monero-wallet-cli. At the time of writing this post, the update is available for download from the beta-wallet page. I didn't have to enter my seed again but don't proceed without having it nearby.

Trezor One also received an update which includes Lisk, Stellar and Zcash Sapling hardfork support. What about coins which were added for Trezor T? Not all of them will be available due to hardware limitations. TREZOR is porting the trezor-core (Trezor T software) to Trezor One so that it could have some features and coins of the model T.
14  Bitcoin / Development & Technical Discussion / Basics of the Lightning Network on: August 22, 2018, 07:43:13 PM
Introduction

This thread contains some more detailed information that has been already mentioned in the set of questions answered by me. Below you will see an explanation of the Lightning Network basics. We had many discussions on bitcointalk whether or not it is a good scaling solutions. Here are the most popular threads: Is the Lightning Network centralized?, Lightning Network Discussion Thread, Lightning Network fraud possible?

Table of contents

      1. What is the Lightning Network?
      2. How does it work?
      3. Wallets and nodes
      4. Known problems
      5. Planned features
      6. Security risks
      7. Other second-layer scaling solutions
      8. Useful sources of information

1. What is the Lightning Network?

The Lightning network is an alternative to the traditional Bitcoin on-chain transactions. It doesn’t replace them completely because on-chain transactions are still needed for closing and opening payment channels. The Lightning Network is a second layer solution and is fully opt-in. Transactions done between Lightning Network participants have no negative impact on the Bitcoin network.

The Lightning Network allows for instant and extremely cheap P2P (micro)payments.

2. How does it work?

Creating a payment channel

What is exactly a payment channel? According to the Bitcoin wiki, payment channel is a class of techniques designed to allow users to make multiple Bitcoin transactions without commiting all of the transactions to the Bitcoin blockchain. A maximum of two transactions will be broadcasted to the blockchain.

To start using the Lightning Network you have to use compatible software. Two people may establish a payment channel by locking up funds in a multi-signature address which needs both signatures to spend from it. This transaction is time locked so that the funds will be automatically dispersed in the event that one of the parties becomes uncooperative. Payment channel can be used as long as both participants remain cooperative.

Sending and routing payments

Both parties transact without broadcasting the current state of their trade to the Blockchain. They both keep the copy of the channel information. Sending payments through the Lightning Network is possible as long as there is at least one connection to the other person and sufficient funds in the channels which route the transaction. Each node is rewarded for routing the payment accordingly to their fee policy.

Secure routing of payments would not be possible without Hashed Timelock Contracts (HTLCs). The example below explains why they are needed.

1. Alice opens a payment channel to Bob, and Bob opens a payment channel to Charlie.
2. Alice wants to buy something from Charlie for 1000 satoshis.
3. Charlie generates a random number and generates its SHA256 hash. Charlie gives that hash to Alice.
4. Alice uses her payment channel to Bob to pay him 1,000 satoshis, but she adds the hash Charlie gave her to the payment along with an extra condition: in order for Bob to claim the payment, he has to provide the data which was used to produce that hash.
5. Bob uses his payment channel to Charlie to pay Charlie 1,000 satoshis, and Bob adds a copy of the same condition that Alice put on the payment she gave Bob.
6. Charlie has the original data that was used to produce the hash (called a pre-image), so Charlie can use it to finalize his payment and fully receive the payment from Bob. By doing so, Charlie necessarily makes the pre-image available to Bob.
7. Bob uses the pre-image to finalize his payment from Alice

Closing the channel

There are two ways of closing payment channels. Cooperative and uncooperative.

The latter method takes more time because the other party is offline. In order to avoid frauds, one have to wait a certain amount of time, which was negotiated while opening the channel, before broadcasting the closing transaction.

3. Wallets and nodes

There are a few Lightning Network implementations and each of them might contain some bugs which may lead to the loss of funds. Most of them require user to run a full Bitcoin node but thanks to neutrino, you can replace it with a light node if you decide to use LND. iOS and Android wallets are easy to use and don’t require much setup but most of them can’t be used for requesting payments.

Each implementation has a different setup process.

Desktop clients


Mobile clients


The above list includes software which is officially available and can be configured for the Bitcoin mainnet usage. Every user running a Lightning Network node takes part in payments routing. The number of routed transactions depends on how well one's node is connected, amount of bitcoins locked up in the channel and the fee policy. There is no point in describing features of these wallets since they are constantly being updated at this state.

4. Known problems

  • offline nodes are considered capable of routing which results in payments not going through in some cases, explained here
  • there is no standard for safe backup. Using an old backup is considered as cheating therefore a penalty transaction is being broadcast,
explained here
  • one can’t receive payments and defend from the other party cheat if one’s node is offline,
  • there still might be a problem with full blocks in the future. However, developers are working on solutions which will increase the number of transactions per block e.g. Schnorr signatures.

5. Planned features

      • Watchtowers – it is possible that the second party will attempt to cheat by broadcasting an old state of the payment channel. Normally, this would not be possible since the other node would broadcast a penalty transaction. To prevent frauds, the concept of watchtowers is being developed. Watchtowers will be able to broadcast a penalty transaction if necessary.
      Added
      • Atomic swaps - trustless method of exchanging two different cryptocurrencies without the need to use escrow.
      • Multi-path payments - currently, one can send transaction using only one route. In the future, it will be possible to split the transaction among multiple routes in order to decrease the fail rate of transactions which is often caused by the lack of funds across the nodes.
      • Dual-funded channels - two users instead of one will be able to fund a payment channel as originally described in the Lightning Network Paper.
      • Eltoo - eltoo will be an alternative to the current method of settling payments between users. Updating channels is done by building a chain of timelocked transactions. A soft fork is needed to make eltoo available on the Lightning Network (in order to avoid having to broadcast the whole transaction history between users). Here you can find out which opcodes need to be modified.
      • Channel factories - existing Lightning Network channels could be used for creating new channels without broadcasting anything to the rest of the Bitcoin network. Normally, a channel is opened to only one person. In channel factories we have multiple people forming a group. Group members maintain channels between themselves. More interested users = higher savings. If one of the participants is uncooperative, existing channels are not affected - new channels can't be created, though.

      There are a few things which can be changed in the Bitcoin code in order to improve privacy. Introducing Schnorr, MAST and Taproot would make transactions opening/closing channel indistinguishable from any other ordinal transaction.

      6. Security risks

      • Improper timelocks - sufficient time should be given in case of interaction with non-cooperative or malicious channel counterparties.
      • Forced expiration spam - closing many channels at the same time might lead to filling up the whole block completely. If the spam lasts enough time, some timelocked transactions might become valid.
      • Data loss - most of the Lightning Network clients don’t provide reliable method of backup. Using an old copy of the database might be considered as cheating. The other party broadcasts a penalty transaction in that case.
      • Coin theft - most of the Lightning Network nodes work 24/7 and store their coins in hot wallets which makes it easier for an attacker to steal their private keys.
      • Colluding miner attacks - miners have power to decide which transactions they want to include in the block so they can refuse certain transactions selected by an attacker. This attack is very unlikely to happen due to high cost and complexity (all miners would have to cooperate).

      Most of the mobile Lightning Network clients will run thanks to neutrino which takes advantage of BIP 157 & BIP 158. Does it have any positive impact? Yes, it helps to save client's bandwidth while keeping the same level of privacy and putting less stress on the full node which shares data.

      General Information

      How are bitcoins on the Lightning Network different from on-chain bitcoins?

      They are exactly the same coins. There are no Lightning Network tokens. The only difference is that bitcoins are stored in multi-signature addresses and transactions are settled between two parties without broadcasting anything to the blockchain (except when opening and closing the channel).


      When will merchants start accepting Lightning Network payments?

      It is a tough question. Many merchants were discouraged from accepting Bitcoin because of high transaction fees. Some of them use third party services which are slowly working on the Lightning Network support. Here you can find a list of stores which accept Lightning Network payments.


      How many times can we expect to be able to use a payment channel?

      Every channel has a minimum amount of coins which has to stay unspent. Channels can be used as long as both parties continue to cooperate with each other.


      How fast and reliable are Lightning Network payments?

      Depending on the route, Lightning Network payments can be instant. Every wallet tries to find the cheapest and the shortest route once you send your transaction. You can open a channel directly to a person who you are going to often trade with or depend on other channels which might route your payment for a small fee. Lightning Network is still in its early state so payments fail from time to time.


      What are the upcoming features?

      Dual funded channels - both parties will be able to fund a channel.

      Watchtowers - they will be responsible for taking care of people attempting to cheat while the other party is offline.

      Muilti-path payments - currently, the payment can't be divided into smaller ones which sometimes results in failed payments due to not enough funds in the channels.

      Sphinx - users will be able to send payments without having to ask the other person to generate an invoice.

      You can find more here.


      Where can I find the latest news regarding the Lightning Network?

      Telegram channel - a whole group of knowledgeable people ready to talk about the Lightning Network. Great source of information.

      Bitcoin Lightning - a website strictly focused only on the Lightning Network.

      Cointelegraph - nothing to add here.


      Which wallet is the best one?

      There are multiple implementations of the Lightning Network and most wallets have similar features. However, some mobile wallets can't receive payments. Eclair is the most popular wallet for Android but it is also available on Windows. The most popular implementations are: c-lightning, LND and eclair mentioned earlier.


      Running a node

      How much money can you make on running a Lightning Network node?

      Don’t expect to make a lot of money. Everything depends on the number of connections and your fee policy. The less you charge, the higher your chances to route a payment. Don’t set the fee too low. You have to save up money for future channel re-balancing. User Xian01 opened almost 200 channels and earned barely 15 satoshis after 2 weeks (Reference).


      How do channel owners get paid for routing payments?

      Fees earned from routing payments are added to the balance of the channel. The total fee charged is basefee + (amount * feerate / 1000000), where amount is the forwarded amount. If you set both of these values too high, you won't route any payments.


      Is running a Lightning Network node demanding?

      You can run a Lightning Network node on both Linux and Windows. You have to run a Bitcoin full node which uses the biggest part of available resources. In order to start making money on running a node, you have to open a few channels. Keep in mind that built-in autopilot might not guarantee you the best connections. Even Raspberry Pi 3 B+ is capable of running a Lightning Network node. Check out RaspiBlitz for fast setup.


      Is there any risk in running a Lightning Network node?

      Yes, due to many factors. Lightning Network implementations are still in beta and might contain critical bugs which could be used to steal funds locked up in channels. Keep in mind that if you won't keep your node online 24/7, someone can attempt to cheat you by broadcasting an old state of your channel. An online node would normally broadcast a penalty transaction.


      Does opening new channels help to increase the earnings?

      No, it doesn't. There are many other things that you should take into account. Your fee policy, channels' capacity, connection to different sized nodes. Here you can find an interesting comparison between Andreas Brekken's and Alex Bosworth's nodes. The node which had lower principal, made higher profit.


      Do I have to run a full Bitcoin node?

      No. LND supports neutrino which allows user to run a light node instead of a full one. It is a good solution for devices with low processing power and storage (Raspberry Pi).


      How do I set up a Lightning Network node?

      The setup process varies for each implementation. Fortunately, detailed documentation makes it easy for inexperienced users to start their own Lightning Network node even on Linux. If you don't feel confident with any other operating system than Windows then take a look at this tutorial which will help to set up your own node.


      What is the purpose of setting alias and color?

      This information is often used by Lightning Network visualisers and explorers. It is not very important and has no impact on how the node works.


      Do I have to generate an invoice every time I want someone to send me coins over the Lightning Network?

      Currently, in order to receive a payment over the Lightning Network, a single-use invoice has to be generated. However, Sphinx will allow users to send payments without having to request the invoice from the other person. Sphinx can be already used if both nodes update to the test branch.


      Can I refill my channel?

      Currently, there is no way to refill channels without using third party services such as Lightning Conductor. Splicing will allow users to either top-up their channels or drain funds from them without having to reopen the channel. Channel balance will be updated once the transaction gets enough confirmations.


      Why can't I receive coins?

      In order to receive Lightning payments, some conditions must be met:

      1. Nothing can be received immediately after creating a new payment channel, as ‘room’ for incoming funds has to be made by spending some funds first. A payment channel can be thought of as a full bottle of water: in order to pour something in one first has to pour something out.

      2. Each channel implicitly contains a reserve which is unspendable and typically takes about 2% of the channel’s capacity. You must spend an amount matching that reserve to make receiving possible. Unspendable channel reserve is the reason you see a negative receive limit when a new channel is full. It indicates how much you need to spend before anything can be received through the channel.

      3. Every payment request is disposable, they can’t be fulfilled twice. So you will need to issue a new individual payment request for every incoming payment you wish to receive.

      4. Wallet needs to be online in order to receive off-chain funds.

      Note that not every mobile wallet supports receiving coins because of the fourth point. There are some exceptions such as Bitcoin Lightning Wallet (Android), Eclair Mobile Testnet (Android).

      Concerns

      Is Lightning Network centralized? Is it more centralized than Bitcoin? Does it make Bitcoin more centralized?

      This topic has been brought up many times. The Lightning Network is a second layer scaling solution which has no impact on the Bitcoin network. It works independently and no one is forced to use it. The problem of large nodes should solve itself once network continues to grow.


      Will casual users be able to accept payments and donations without having to run their own full node 24/7?

      Both OpenNode (payment gateway) and Bitlum.io allow users to receive Lightning Network payments without having to run a full node. However, these wallets are custodial which means that they have a full control of one's funds.


      What are the new limitations of scalability once lightning is fully functional?

      Opening and closing a channel requires broadcasting a Bitcoin on-chain transaction. Increasing the blocksize might be necessary in the future; however, solutions like SegWit, Schnorr signatures can help to decrease the size of transactions. Lightning Network is a second layer protocol, it is possible to build more user-friendly layers on top of it.


      What would happen if a large node disappeared from the network?

      Recently, we were able to observe Andreas Brekken’s experiment (shitcoin.com node). He was in charge of a node whose capacity was around 43 BTC (more than 50% of the whole network’s capacity!). After its closure, some people started to experience routing problems.


      Is Lightning Network more anonymous than on-chain transactions?

      Lightning Network increases the level of privacy. The next node doesn’t know if the previous one initiated the transaction. Every node which routes the payment doesn’t know the details of the transaction (final destination, sender).


      What happens if some nodes go temporarily offline?

      The problem of "zombie nodes" hasn't been solved yet. Offline channels are still considered as capable of routing payments which in some cases cause the payment to fail because channels are unavailable. It is a matter of making a few changes to how channels signalize their state. More information can be found here.

      This problem has been addressed in the v0.5 release of LND. When a channel is being closed or a peer node has gone offline, the rest of the network is informed that they are incapable of routing payments. It is also possible to create unadvertised channels which won't route payments.

            1. General Information
            2. The most popular hardware wallets

      General Information

      What are hardware wallets?

      Hardware wallets are devices designed to store private keys and sign transactions independently from the computer. Their main advantage is being able to use them even on an infected computer. These days, most hardware wallets have built-in screen on which user can check whether or not the destination address was modified by a malware. However, it is not possible to store every cryptocurrency on a such device. It all depends on the support of the manufacturer.

      What if I lose my wallet or destroy it?

      At the first boot, every hardware wallet generates either 12 or 24 word seed which you can later extend with a custom passphrase. This seed can be used to recover coins using third party software, for example, Electrum. It is recommended to test the seed before sending any coins to the generated address. Exposure of the seed should be considered as a major security issue and coins should be urgently moved to another address not associated with the same seed. Firmware updates sometimes wipe the device, keep that in mind before updating your device.

      Are hardware wallets completely safe?

      No, there is no perfect solution. A few vulnerabilities have been found in the most popular hardware wallets but they required a physical access to the device. Here are examples of attacks that were possible to perform on TREZOR One and Ledger Nano S. If you don't trust hardware wallets because of that, you should consider using a cold storage. It's less convenient but it provides higher security.

      Choosing a proper wallet

      Every hardware wallet is different. It is difficult to recommend only one model but there are only a few companies which sell trustworthy devices. Keep in mind that you are not paying only for the device but also for a long-term support. It would be a shame if your wallet didn't get an update after, for example, SegWit was activated.


      The most popular hardware wallets

      Ledger Nano S





      This device is maintained by a French company. Ledger decided to use Secure Element which checks on every boot if the software on the device was modified. Some people are not keen on this solution since it's not completely open-source. You can either use Electrum or Ledger's Chrome app to access your wallet. It will be soon replaced by a new desktop and mobile client which will have more features. Currently, their Chrome app seems to lack some useful features such as using your custom backend and signing transactions without broadcasting them. To send specific coins you have to install a proper app on your device using Ledger Manager. Because of Secure Element, the available space on this model is quite small. However, you can uninstall apps anytime and your coins won't disappear. Later, you will have to reinstall the app which takes some time.

      Ledger Nano S supports a huge variety of altcoins which is why many people choose it. You can find a full list here.


      Ledger Blue





      Big touchscreen, built-in battery, Bluetooth connectivity (not used by any app) and a larger memory are things which differ this model from Nano S. Due to high manufacturing costs, Ledger decided to stop selling this device. At the time of writing this guide, the last batch of ten thousand devices is available. Its support has been much worse than the other model, but Ledger is trying to make up for it.


      TREZOR One





      TREZOR is one of the most trustworthy hardware wallet manufacturers, located in Czech Republic. TREZOR software is fully open-source so anyone can contribute and help with implementing more coins. TREZOR is constantly upgrading their web wallet interface - you can find many features which are not supported natively by other hardware wallets. The device doesn't have any pre-loaded firmware. Due to security measurements, it's downloaded from TREZOR's servers on the first boot. Some users might find it difficult to input PIN and the seed recovery is done on the computer.


      TREZOR T





      TREZOR T runs on a completely different software written from the scratch. Developers claim that it will make adding more coins easier. This model has a touchscreen which allows user to input PIN and passphrase on the device screen. SD card slot is definitely an unique feature. In the future, it will be possible to store files which will be automatically encrypted with your private key. This model will soon support Monero and Ripple.


      KeepKey





      KeepKey has been recently bought by ShapeShift. This device has less features than models described above. However, the developers are trying to make up for it. KeepKey does not support native SegWit addresses (it's not possible to receive and spend from them). You can use either Chrome extension or Electrum to manage your coins. Because of the large screen, it might be difficult to hide or transport this wallet.


      OpenDime





      OpenDime is a small USB stick which you can hand out to any person you want. The device generates private keys and does not expose them (even not to the owner) unless the seal is void. There is no need to broadcast a transaction to the network, it's useful especially if the transaction fees are too expensive. You can simply give it to the other person.


      Other hardware wallets worth attention

      Coldcard





      This device doesn't have any specialized software. It works with some well-known software wallets. The device has a micro SD card slot which can be used for data storage and transporting (un)signed transactions. Currently, it's only available as a pre-order. It's worth to mention that you can use multiple PINs (accessing different wallets or even bricking the device).


      BitBox





      A small wallet created in Switzerland. Wallet data is stored on a micro SD card. Instead of built-in screen, this device has a touch button which is used for accepting and rejecting transactions. It is possible to use a smartphone to verify if the recipient's address is correct. It does not support as many altcoins as Ledger and TREZOR.


      Bitlox





      Credit card sized wallet with e-ink screen which doesn't require much power. Bluetooth can be used to communicate with a mobile device and a micro-usb cable with a computer.


      Comparison of wallets

      Which one is better? TREZOR or Ledger?

      It all depends on your needs. Ledger mostly focus on supporting more and more altcoins while TREZOR developers are adding more advanced features to their wallet. I would recommend TREZOR for anyone who is not interested in altcoins. Their build quality and support is almost equal (TREZOR team responds very fast not only through their ticket system, but also GitHub and Telegram).

      What is the difference between TREZOR One and TREZOR T?

      TREZOR T is going to support more coins in the future because of new hardware and software. Touchscreen in TREZOR T allows for a secure input of PIN, passphrase and the seed in case you want to recover your coins.

      Which device is more future proof?

      If you decide to buy either TREZOR or Ledger you won't have to worry about future Bitcoin forks. Don't expect to be able to claim every single one without exposing your keys to a third party software. More advanced features such as touchscreen and additional connectivity are useful, but they might easily break, it will make your device useless.

        Chcielibyśmy przedstawić naszą usługę w formie FAQ. Pełne odpowiedzi znajdziesz na naszej stronie.

        Na czym polega proces mieszania?
        Całość jest bardzo prosta. Przesyłasz nam swoje monety, a my wysyłamy monety z naszej rezerwy. Otrzymasz BTC, które nie są powiązane z twoją historią transakcji.

        Jak długo trwa proces mieszania?
        Wszystko zależy od ustawionego wcześniej opóźnienia, które ustawiłeś podczas składania zlecenia. Pamiętaj, że opóźnienie jest liczone od momentu kiedy transakcja będzie miała 2 potwierdzenia (szczegóły poniżej), a nie od momentu złożenia zlecenia. Kiedy wyznaczony czas minie, nasz system automatycznie wyśle monety.

        Czy transakcje z opóźnieniem są wysyłane od razu?
        Nie, transakcje z ustawionym długim opóźnieniem wysyłamy z różnicą do 10 minut. Robimy to aby zapobiec śledzeniu transakcji, które mogłyby zostać potwierdzone w tym samym bloku. Z kolei, nagłe płatności są wysyłane natychmiastowo po otrzymaniu wymaganej ilości potwierdzeń.

        Ile potwierdzeń jest wymaganych?
        Potrzebne są przynajmniej 2 potwierdzenia.

        Jak długo wygenerowany przez was adres jest ważny?
        Wygenerowany przez nas adres ważny jest przez 24 godziny. Wszystkie transakcje przychodzące po tym czasie będą ignorowane. Wszystkie dane dotyczące zlecenia są usuwane natychmiast po przesłaniu monet do wszystkich adresów.

        Jakie informacje są zbierane i przechowywane?
        Nie przechowujemy żadnych logów ani informacji, które mogłyby pozwolić na zidentyfikowanie naszych klientów. Wszystkie logi są usuwane natychmiast po wykonaniu przez nas zlecenia w celu zwiększenia anonimowości naszych użytkowników.

        Czy mogę zmienić opłatę transakcyjną dla adresów docelowych?
        Tak, oferujemy taką możliwość w momencie składania zlecenia. W przypadku gdy transakcja nie zostanie potwierdzona w ciągu 5 bloków, zostanie ona przez nas wysłana ponownie z większą opłatą transakcyjną.

        Czy używacie adresów SegWit?
        Każdy z naszych adresów wspiera SegWit (nested) dzięki czemu korzystanie z naszych usług jest tańsze. Wspieramy także możliwość wysyłania BTC do adresów typu bech32.


        Przez pewien czas prowadziliśmy kampanię mającą na celu zebranie recenzji i otrzymaliśmy wiele pozytywnych opinii. Dziękujemy wszystkim osobom, które pomogły nam w rozwoju. Poniżej znajdują się najbardziej niezapomniane opinie.

        Nie zapomniałem o was. Brałem udział w pierwszych testach i napisałem opinię pochwalającą wygląd interfejsu, który świetnie wygląda na urządzeniach mobilnych. Specjalnie spróbowałem przemieszać trochę monet jeszcze raz aby przetestować adresy SegWit. Wysłałem .002 BTC z opóźnieniem i ręcznie ustawioną opłata transakcyjną. Zero problemów, całość łatwa i przejrzysta. Wróżę wam świetlaną przyszłość. Chciałbym zobaczyć większą maksymalną kwotę możliwą do przemieszania, ale jest to zrozumiałe gdyż to są wasze początki. Obojętne jest mi czy dostanę nagrodę za opinię.

        Zleciłem przemieszanie bitcoinów z 5 godzinnym opóźnieniem i otrzymałem monety bez żadnych problemów. Wysłałem monety z adresu SegWit (nested) jak i otrzymałem monety na ten sam typ adresu. Sprawdziłem stan mojego zlecenia po otrzymaniu monet i na stronie nie było żadnego śladu. Cieszę się, że informacje są usuwane. Po pierwszym użyciu tej usługi mogę śmiało powiedzieć, że jest bardzo łatwa w użyciu; to jest najłatwiejsza w obsłudze mieszarka z jakiej dotąd korzystałem.

        Nie muszę tego mówić, ale powiem: Dodałem tą mieszarkę do listy usług, z których często korzystam.

        Nie ma potrzeby aby wysłać mi nagrodę za moją opinię. Mam nadzieję, że ta usługa będzie dalej się rozwijać i generować zyski. Mam nadzieję, że zdobędziecie więcej pozytywnych opinii, ręczę za was! Świetna opcja na polepszenie prywatności!

      I am surprised that nobody has mentioned it here yet. GDPR (General Data Protection Regulation) was implemented on 25th May. If you didn't hear about it then you are probably living under a rock. GDPR is supposed to let European Union citizens control their personal data.

      A lot of people have been complaining about GDPR. Some people say that it is a huge hassle for small businesses because it increases the amount of work that needs to be done and preparations which, in some cases, might have been expensive. There were 2 years to prepare for the GDPR so why so many people are complaining? It wasn't a sudden change in the law, but, still, there are many websites which decided to simply block the EU IP address ranges.

      I would like to hear opinions of European and other bitcointalk members.

      It's been quite a long time since TREZOR released their Connect API. It could become an alternative way of logging in for people who own a TREZOR device. People are more likely to use a weak password than expose their seed with additional passphrase.

      You can find more information about it in the link below.
