Wallets which can be recovered using the seed are called hierarchical deterministic. Their main advantage is that they are easy to backup. You can use them on multiple devices without having to worry that some of your coins won't be available on a specific device. Modern software and hardware wallets use this kind of wallet. Bitcoin Core instead of the seed allows user to export Master Private Key in its console.

Witaj!

Wszystko zależy od jakości twoich postów i w jakich działach je dodajesz. Łatwo jest rozróżnić posty osób, które są tu tylko dla zarobku, a które chcą faktycznie pomóc. Jak będę miał wolną chwilę to przeglądnę twoje posty i jak znajdę coś ciekawego to nagrodzę meritem. Z chęcią porozmawiam na PW/Telegram (@BitCryptex).

Obserwowałem 777Coin i nie poleciłbym jej nikomu w tym momencie. Nie tak dawno temu zalegali z zapłatami przez około 10 tygodni. Najlepszą kampanią w tym momencie jest ChipMixer, ale dostanie się do niej to nie lada wyzwanie. Stawka jest kilkukrotnie wyższa niż w 777Coin, ale wymagana jakość postów jest znacznie większa. Ostatnie 10 miesięcy spędziłem na pisaniu poradników i pomocy innym użytkownikom z Lightning Network (link do moich tematów) co jak widać zostało docenione.

Spróbuj częściej zaglądać do sekcji, w których ja dodaję posty. Miło jest komuś pomóc, a przy okazji wyżsi od ciebie rangą na pewno cię docenią. W moim przypadku dojście do Full Membera zajęło mi cztery miesiące, a z Full Membera do Seniora już tylko jeden.

Yes, full nodes are responsible for validating blocks and transactions, and relaying them to other nodes. They can also filter transactions on behalf of lightweight clients which are used by the vast majority of users (e.g. Electrum). Increasing the blocksize leads to higher disk space and bandwidth usage - this might discourage volunteers from running their own full nodes. Mining centralization is also a big problem. If one mining pool controls the vast majority of hashrate, it can reject certain transactions.

It means that someone has sent you 0.000001 BTC multiple times and you have sent 0.0000016 BTC once. It looks like you haven't used Electrum a lot. Take at Electrum tutorials which I wrote for beginners and advanced users.

Don't forget that you will pay a lot in the future for a transaction if you decide to send everything from your wallet to a different address. Every 0.000001 BTC transaction is a separate input which will increase the size of the transaction. Learn more about it here. It might be a bit confusing for you at the beginning, focus on Electrum first.

That's exactly the guide which the other person followed and experienced some problems with setting up his Lightning Network node since the guide is a bit outdated. You can either use solutions from this thread or install a new operating system according to this tutorial which is easier than the one you have posted above.

The command which I gave you probably won't work anyway because your LND seems to be stopped.

That was not the point. Every time you receive some BTC to the same address, the coins are considered as separate inputs. For example, if you receive 0.1 BTC four times you will pay more for your cash-out transaction than as if you received 0.4 BTC. Right now, transactions with 1 sat/b confirm quite fast. A year ago, I had to pay almost 70 sat/b so I prefer to consolidate my inputs from time to time.

Only some Bitcoin Core instances are vulnerable (0.14.0 to 0.16.2). If they receive a block with a transaction which has a duplicate input, they will crash. No new coin would have been created but it could pose a huge threat to the network. You can find more information here and here.


Yes, some Bitcoin clones are affected and their clients have to be patched by their developers manually. Bitcoin Cash and Litecoin are safe.

Actually, that's a good question. Every single transaction you receive to your wallet is a separate input. The more inputs your transaction has, the higher fee you will pay. It's a good idea to combine a few inputs into a big one when the fees are low (1-3 sat/b) since you will save a lot of money in case you decide to cash out when the fees become extremely high again. Loyce has explained it here quite well.

Which tutorial did you follow? Some time ago, I helped another user with setting up LND on the Raspberry Pi. He followed this tutorial and it turned out that it was a bit outdated. What about other commands? Have you tried using other commands? (e.g. lncli connect <nodeid@ip>)

I recommend you RaspiBlitz if you decide to start everything from scratch. It is easy to use and has a quite good documentation. It also support LCD displays.

As you wrote, Ethereum is not available in the web interface. They are working on it but there is no specified date. However, ShapeShift accepts Ethereum. In order to trade it, you have to create an account on ShapeShift and send your Ether from MyEtherWallet to the address generated by them. You can also do it on Changelly (registration needed as well). TryNinja has already explained you why there is nothing to worry about. Using "Exchange" feature is basically the same as what I described above - Trezor sends whatever you exchange to ShapeShift's address.

Currently, TREZOR supports every Ethereum token which follows ERC20 standard. Support for token which follows a different standard needs to be added manually. I was told by one of the TREZOR Telegram channel admins that they do that and list such coins here. However, I can only see ERC20 tokens there. It would make sense if they had already added Ethereum to their web wallet. Don't you think that the above list is targeted to newbies which don't understand tokens?


As far as I remember, 1.6.2 update wiped my device's memory while 1.6.3 didn't. You have updated your device directly to 1.6.3 so that's the reason.

The Lightning Network is working quite well despite being still in an early-state. Broadcasting on-chain transactions is need for opening and closing channels but we can lower the cost of doing so and improve privacy by introducing Channel factories and Schnorr signatures. Unfortunately, it will take a lot of time to implement each of these solutions.

The same applies to Bitcoin, doesn't it? This kind of attack would be used for revising already confirmed on-chain transactions with far higher amount of BTC rather than for manipulating channels which have a maximum capacity of about 0.16 BTC.

There is no specified date. According to this page, in the next update of trezor-core they will add support for Tron, EOS, Ontology and implement SLIP-0039. If you want to use a native SegWit address (bc1), you can do it in the latest Electrum. Your address should show up in their web wallet after they add support for this type of address.

Pozwólcie, że dodam parę słów od siebie.


Wspominałem już w innym temacie, że zazwyczaj nie przeglądam sekcji gdzie postują nowi użytkownicy, którzy mają mały zasób wiedzy. Efektem tego jest 119 merita do rozdania (zaczynałem mając 10 więc stąd taka duża ilość). Polska sekcja w porównaniu z innymi jest mało aktywna. Czy to przez to, że mamy osobne forum w naszym języku?


Jak już wyżej wspomniano, od niedawna aby zostać Jr. Memberem należy dostać przynajmniej 1 merit i mieć odpowiednią ilość activity. Osoba posiadająca nowe konto może zakupić rangę Copper Member, która pozwala między innymi na dodawanie obrazków w postach oraz daje kilka przywilejów, które posiadają Memberzy. Na przyszłość polecam odesłać taką osobę tutaj.

Since not everyone here browse "Development & Technical Discussion" section, I would like to inform you that TREZOR has released a new software update for both Trezor One and Trezor T. Monero support is finally here! However, it is not available on the older model due to hardware limitations and it can be accessed only in the monero-wallet-cli (GUI has been not updated yet). The update is available only in the beta wallet. If you want to know what the new coins are, check out the topic which I posted recently.

You don't have to run a full node to use Bitcoin. You can either use a SPV client (e.g. Electrum) or prune your node. Bitcoin blockchain is not as big as Ethereum's (most of its nodes are pruned ones). What we are currently trying to do with Bitcoin is moving some of transactions off-chain so that they could be made instantly and cheaply while putting less stress on the network. The Lightning Network, Liquid and RSK are examples of such solution.

Sharding is a bit complicated and it won't be implemented anytime soon. You can learn more about it here. The author of this text used Ethereum as an example.

It depends on the timelock which is always negotiated while opening a channel, usually it's 144 blocks (~1 day). Your case is a bit weird. Can you show me the output of lncli listchannels? It might show some information about these channels (I doubt it since the transaction has been already confirmed). Have you tried restarting your node?

Lightning Conductor opens channel back to those who open a channel with at least 0.0025 BTC to them. Balancing a channel would mean that all of your channel funds were used up for routing payments. This would force you to reopen your channel if you wanted to continue using your channel safely.

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.
