Bitcoin Core :: Bitcoin Core 24.0.1

Point that we're recording this, the new Bitcoin Core release has not actually been released yet.Bitcoin Core 22 has not actually been released yet.But by the time this episode is released, then maybe Bitcoin Core 22 is released as well.And otherwise, it will be released very soon, right?Sjors: 00:02:41That's right.There's now a third release candidate out.Aaron: 00:02:44So that means basically any day now, at the point of recording at least.And maybe, like I said, maybe it's out by the time this episode is released.So anyways, we're going to highlight some of the improvements compared to Bitcoin core 21 essentially and bitcoin core 21.1. Was there a bitcoin core 21.2 as well?I don't think so.Sjors: 00:03:09I think there's one in progress.Aaron: 00:03:11Right exactly yeah there's one coming as well.So we're gonna give a short overview of the most notable changes, right?Sjors: 00:03:22Yeah, exactly.So usually the last version digit, those changes are very small.They're usually bug fixes and those kind of things.So the release we're talking about now is a big one.Aaron: 00:03:32They're either very small or they're a protocol upgrade.Sjors: 00:03:36Right.So in this case, it's a bit more complicated because it's small fixes and taproot that go into 0.21.1 and also probably in 0.21.2.Hardware Wallet Support in the GUIAaron: 00:03:47So let's get to Bitcoin Core 22.That's what the episode is about.I think the main, the most notable change, the biggest change, and I think you'll agree with that because you worked on it, so you're biased, is hardware wallet support, the HWI, right?Sjors: 00:04:06I think that's a pretty cool change.I don't know if it's the biggest change.I'm definitely very happy with it.Yeah, so basically if you download Bitcoin Core 22 and then also download HWI, which we talked about in episode 30, which is just a Python script that connects to all sorts of different hardware wallets essentially using their drivers.Then I think you just have to change one setting which is to tell it where you put the HWI script and then once you've done that you just insert your hardware wallet you say to Bitcoin core give me a New wallet and it'll say "oh do you want to use a trezor, ledger whatever you've just inserted" and it'll just work to him like any other wallet except that your wallet your hardware device will now show on screen "hey do you want to prove this transaction" so that's pretty cool I think.Aaron: 00:05:01Right, but am I understanding you correctly that it does not work out of the box?You can't only download Bitcoin Core 22, you also need to download the HWI.Sjors: 00:05:11Correct.Aaron: 00:05:12Which is a separate software package.Sjors: 00:05:14Yeah, It's a Python library and you know because it contains all the stuff from the hardware manufacturers and it communicates with USB so it is potentially a can of worms and so we don't want to put it in Bitcoin Core for everybody.Maybe one day will be but I think it'll be a while because just including USB drivers into Bitcoin Core sounds a bit scary.Aaron: 00:05:35Right.So for now it's like an add-on.Sjors: 00:05:38Yes.But like I said, pretty easy to install.You download it, put it somewhere, point to it, and that's it.Aaron: 00:05:44Hardware wallets were already supported by Bitcoin Core though, right?Sjors: 00:05:48Indirectly, yes.You could use HWI already, but you had to use it from the command line yourself.And actually HWI also came with a graphical tool, so you could actually use it somewhat you know reasonably, but I think this is much easier now.It's just right into the Bitcoin Core interface.Bitcoin Core InterfaceAaron: 00:06:08Yeah, no one uses the command line, sure.So only a couple of Bitcoin Core developers themselves use that stuff.Regular people.Sjors: 00:06:16A surprising number of Bitcoin Core developers use the graphical interface too and it's especially because coin selection is just a lot easier to do if you want to decide which coins you want to spend using a graphical interface you just click on them whereas with a command line it's horrible, you have to copy paste the transaction hash and the identifier, etc.Which Hardware Wallets are SupportedAaron: 00:06:37Right.So, which hardware wallets are supported?Sjors: 00:06:41Off the top of my head, whatever HWI supports.So, that is

IntroAaron: 00:00:20Welcome to Bitcoin Explained, the podcast with the most boring name in Bitcoin.Hey Sjors.Sjors: 00:00:27What's up?What's with the new name?Aaron: 00:00:29So We've rebranded our podcast.What do you think?Sjors: 00:00:33Well, I think, you know, especially if you read it correctly, Bitcoin, explained.I think it's an amazing name.I think the problem was that a lot of people have no idea what the hell a Van Weerdam Shores Nado is.Aaron: 00:00:46Apparently, no one had any idea what Van Weerdam and Shoresnado means or even how to pronounce it so we decided to go for a new name.Sjors: 00:00:54Though I think if people listen to it long enough they'll know how to pronounce it but I think the problem is people who are not listening don't know how to pronounce it.Aaron: 00:01:02So from now on, we're Bitcoin, Explained.Why is the comma so important for you?Sjors: 00:01:07It makes it sound more profound.So if you just say, oh, I'm going to explain Bitcoin, whereas Bitcoin, Explained, you know, really says, okay, now You truly understand it.Aaron: 00:01:16Very profound.So the first episode, we're just going to keep counting.So this is episode 45 of Bitcoin Explained, previously known as Defend William Shures NATO.And we're going to start off with the new Bitcoin Core release, Bitcoin Core 22.Sjors: 00:01:33That's right.Aaron: 00:01:34From now on it's not 0.22 anymore, it's just Bitcoin Core 22, right?Sjors: 00:01:40Yeah, highly undemocratically decided at some point to just change the numbering because people were asking when is version 1 coming of Bitcoin?And we're like yeah we're just gonna skip it because it's always bad luck when you do that.Aaron: 00:01:53Right so from now on it's does this mean we're not in beta anymore Sjors?Is that the big announcement?Sjors: 00:01:59No I think it means nothing I think it just means that we stopped having this zero prefix.Aaron: 00:02:05Basically, Bitcoin Core changed the name for the same reasons that we did, just to avoid annoying questions and make it more clear.Is that it?Sjors: 00:02:14I guess.I wasn't really there at the decision.It just happened and nobody wanted to undo it.So there we are.Aaron: 00:02:22Got it.Well, at the. And we're going to start off with the new Bitcoin Core release, Bitcoin Core 22. That's right. From now on it's not 0.22 anymore, it's just Bitcoin Core 22, right?

The Trezor, the Ledger, the KeepKey, Coldcard.I don't know.Aaron: 00:06:55Maybe some more.Sjors: 00:06:57Yeah, I was just opening the support matrix.There's a whole list of it.Bitbox.Aaron: 00:07:04Okay.Is that the only hardware wallet related change in the Bitcoin Core 22?Sjors: 00:07:11I mean, that's a big enough one, right?And I'm sure in next versions, there'll be some more incremental improvements, like being able to bump the fee for example would be nice, that sort of stuff.Multi-sig would be very nice if it was possible to do that directly.Aaron: 00:07:26Yeah, and for now I think it's just one hardware wallet per Bitcoin Core wallet, right?You can't do two out of three or that kind of nifty stuff yet.Sjors: 00:07:37No, exactly.Multi-signature support is not there yet.And that just is a whole can of worms in general, right?Multi-signature support with Bitcoin Core is still not very easy.It does, it's all possible, but it's, it requires some manual work.Aaron: 00:07:51Let me think.Should we say something else about hardware wallets?Or is that about it?But there is also RPC.Sjors: 00:08:00No, right?But yes, that is indeed that you can do it via the GUI or the command line.I don't know how important it is to do that.Aaron: 00:08:09Right, so hardware wallet integration into Bitcoin Core has been a long process, has been an incremental process And now for the first time with Bitcoin Core 22, we have hardware wallet support in the GUI, which basically means we for the first time have hardware wallet support for regular users.Sjors: 00:08:26Yeah, exactly.I think it's still marked experimental.Aaron: 00:08:29Great.I2P SearchAaron: 00:11:56Next up, I2P.What is I2P?Sjors: 00:12:01I don't know.There's a lot of articles on the internet that say what is the difference between I2P and Tor and then those articles start by saying many people ask what the difference is between I2P and Tor and then they proceed in some really convoluted language.But basically, it is a Tor-like system that is somehow different.But the good news is that Bitcoin Core can now use it.Aaron: 00:12:24Exactly.It's a privacy layer on top of the internet, a lot like Tor.Tor uses onion routing, so messages are encrypted Security, and decentralization is what Vitalik Buterin, the creator of Ethereum blockchain, dubbed the "Blockchain Trilemma". Bitcoin's shortcomings in these areas has led to the rise of other cryptocurrency competitors, though Bitcoin still dominates when it comes to price and market cap.How is Bitcoin different from other cryptocurrencies?While Bitcoin is not the only cryptocurrency, it is different from all others for a variety of reasons.First and foremost, Bitcoin is the original cryptocurrency, launched in 2009. Every other cryptocurrency is known as an alternative coin, or “altcoin” since each one was developed after Bitcoin.Secondly, Bitcoin has by far the largest and most active community of developers working on it. Well over 1,000 developers have contributed code to the Bitcoin Core project since its inception. This means there is a lot of talent and resources being used to making Bitcoin better.Finally, Bitcoin is the most decentralized cryptocurrency. There is no centralized authority or company that controls Bitcoin. Instead, it is maintained by a global network of computers that anyone can join. Most of the other cryptocurrencies have fewer miners or validators, which makes them less decentralized than the Bitcoin network.Bitcoin Pizza DayAlthough Bitcoin launched in 2009, there were not yet any real-world use cases for it, and no company was ready to accept it. In fact, most people weren't even aware of its existence.This all changed on May 22, 2010, when Florida-based programmer Laszlo Hanyecz made the first real-world purchase using Bitcoin. He bought two pizzas from a Papa John's outlet for 10,000 BTC, which at today's prices is worth millions. (Image source)This event is now celebrated as Bitcoin Pizza Day every year on May 22, and serves as a reminder of how Bitcoin can be used to buy real-world goods and services.Interesting facts about BitcoinWhile BTC is the abbreviation used by cryptocurrency exchanges and most people, the ISO-prescribed abbreviation for Bitcoin is "XBT."Bitcoin is deflationary in nature. It has a maximum supply of 21 million BTC.The last Bitcoin is expected to be mined in the year 2,140.Experts predict that after the last Bitcoin is mined, the blockchain fee will be the

And routed across different users that all have a sort of encryption step on the way.And therefore you gain privacy.I2P is similar and the differences are pretty subtle.It seems that I2P has a more distributed way of mapping the network.I don't think either of us knows the details of how that works exactly, but it's more distributed than with Tor.And somehow, I2P is more dedicated to...What's it called?Sjors: 00:13:20Well, it's internal, so it's more difficult to get out of I2P, whereas in Tor, it's very easy to use the original internet in addition to dedicated darknet, or not darknet, but onion sites.Aaron: 00:13:33Yeah, that's what I was going to say.I2P is more dedicated to hidden services.So if you stay within the network I2P is sort of specialized for that, where Tor is more usable if you want to you know send stuff to the regular internet to the web.Sjors: 00:13:52That's what we've read in random Google searches, so we wouldn't know.Aaron: 00:13:57These appear to be the subtle differences.So what does this have to do with Bitcoin Core?Sjors: 00:14:00Well, so this kind of ties back into an earlier episode.So first of all, Bitcoin Core 22 supports that network.So if you are interested in using it, you can.Aaron: 00:14:11Yeah, so you can now connect to the Bitcoin network through I2P.Sjors: 00:14:15Yeah, and so what we talked about in episode 13, back when it was still called the Van Wirdum Sjorsnado, what we talked about then is that Bitcoin Core added support for Tor version 3.And the other aspect we talked about then was more generally how does Bitcoin Core tell other nodes which nodes to consider.So there's basically a message where you can say, hey, here's a bunch of addresses for other nodes.And what we explained in an episode is that there's now a new message that makes it easier to announce nodes of various kinds to other nodes including to say okay here's a list of Tor version 3 nodes or here's a list of IPv6 nodes or here's a list of I2P nodes.And this mechanism is now more generic, which. And we're going to start off with the new Bitcoin Core release, Bitcoin Core 22. That's right. From now on it's not 0.22 anymore, it's just Bitcoin Core 22, right?

Bitcoin Core :: Bitcoin Core 0.11.2

Bitcoin Core version 25.0 is now available from: release includes new features, various bug fixes and performanceimprovements, as well as updated translations.Please report bugs using the issue tracker at GitHub: receive security and update notifications, please subscribe to: to UpgradeIf you are running an older version, shut it down. Wait until it has completelyshut down (which might take a few minutes in some cases), then run theinstaller (on Windows) or just copy over /Applications/Bitcoin-Qt (on macOS)or bitcoind/bitcoin-qt (on Linux).Upgrading directly from a version of Bitcoin Core that has reached its EOL ispossible, but it might take some time if the data directory needs to be migrated. Oldwallet versions of Bitcoin Core are generally supported.CompatibilityBitcoin Core is supported and extensively tested on operating systemsusing the Linux kernel, macOS 10.15+, and Windows 7 and newer. BitcoinCore should also work on most other Unix-like systems but is not asfrequently tested on them. It is not recommended to use Bitcoin Core onunsupported systems.Notable changesP2P and network changesTransactions of non-witness size 65 bytes and above are now allowed by mempooland relay policy. This is to better reflect the actual afforded protectionsagainst CVE-2017-12842 and open up additional use-cases of smaller transaction sizes. (#26265)New RPCsThe scanblocks RPC returns the relevant blockhashes from a set of descriptors byscanning all blockfilters in the given range. It can be used in combination withthe getblockheader and rescanblockchain RPCs to achieve fast wallet rescans. Notethat this functionality can only be used if a compact block filter index(-blockfilterindex=1) has been constructed by the node. (#23549)Updated RPCsAll JSON-RPC methods accept a new namedparameter called args that cancontain positional parameter values. This is a convenience to allow someparameter values to be passed by name without having to name every value. Thepython test framework and bitcoin-cli tool both take advantage of this, sofor example:bitcoin-cli -named createwallet wallet_name=mywallet load_on_startup=1Can now be shortened to:bitcoin-cli -named createwallet mywallet load_on_startup=1The verifychain RPC will now return false if the checks didn't fail,but couldn't be completed at the desired depth and level. This could be dueto missing data while pruning, due to an insufficient dbcache or due tothe node being shutdown before the call could finish. (#25574)sendrawtransaction has a new, optional argument, maxburnamount with a default value of 0.Any transaction containing an unspendable output with a value greater than maxburnamount willnot be submitted. At present, the outputs deemed unspendable are those with scripts that beginwith an OP_RETURN code (known as 'datacarriers'), scripts
