Bitcoin Core :: Bitcoin Core 24.0.1

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 And value but also laid the foundation for a decentralized, transparent financial system. Nakamoto’s decision to remain anonymous adds a layer of mystery to the story. As a result, it allowed Bitcoin to stand as a truly decentralized project and remain true to its core tenets.Frequently Asked Questions about Satoshi NakamotoHow Much Bitcoin Does Nakamoto Own?Nakamoto is believed to own over one million bitcoins, which is approximately 5% of Bitcoin’s total supply. This makes them one of the wealthiest individuals or entities in the world.Is Nakamoto Still Involved in Bitcoin?No, Nakamoto withdrew from the Bitcoin project in 2011 and has not been involved since.What’s the Satoshi Nakamoto Wallet Address?The most widely known address associated with Nakamoto is the Genesis Block address – 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa.What Is Satoshi Nakamoto’s Net Worth?With over one million bitcoins in their wallet, Nakamoto’s net worth fluctuates with Bitcoin’s price. As of today, it’s estimated to be over $60 billion, making Satoshi one of the richest individuals in the world. Was this Article helpful? Yes No Thank you for your feedback. 100% 0%

Bitcoin Core :: Bitcoin Core 0.21.2

Full node promises to offer.Sjors: 00:17:18Yeah, but the good news is that if you, you know, if you really, really liked version, say 0.21.0, and you don't want to change too much, then you could just go to 0.21.1 and you'll enforce taproot.But as we'll talk about now, I think version 22 has a few more things on top of this, the consensus enforcement.Aaron: 00:17:39Yes.So what does Bitcoin Core 22 include taproot wise?Sjors: 00:17:44Well, it includes some very rudimentary support for wallet, taproot wallets.Basically you're just a single public key type of wallet, which doesn't make taproot that interesting.And slightly more generic things where you can have one private one yeah one key per taproot branch so remember in taproot you have a main key and you also have scripts that are sitting in a tree.And so there's now support for those scripts in a tree.However, as far as I understand it, those scripts can only be of the super simple type, namely a public key.Aaron: 00:18:27Right.Sjors: 00:18:28So, they're not very interesting yet, but this is how it goes with Bitcoin Core.We add little increments at a time.Aaron: 00:18:35Yes, we've mentioned that a couple of times.Bitcoin Core is improved slowly but surely.Every half year there's a new release, so it's not necessarily that all the taproot stuff comes at the same time.It's just step by step.And now the first step is to have very basic taproot support, which essentially comes down to taproot support for regular transactions.Yeah.So none of the fancy smart contract stuff, but you can use a Taproot type of address and transaction to receive funds.Sjors: 00:19:07Yeah, in principle, but again, it's not even on by default.You actually have to manually make it happen.So probably for version 23, it'll automatically do the Taproot things.Aaron: 00:19:19Yeah.I think another way to put it short, if you, if you agree with me, is that there's no actual benefit yet in using Taproot in this Bitcoin Core release, but it's possible to use it for sort of regular transactions, right?Sjors: 00:19:31Yeah, exactly.So you can if you really know what you're doing.And other.

Bitcoin Core :: Bitcoin Core 0.18.1

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.

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
