Title: Bitcoin Core version 0.12.1 released Post by: Cyrus on April 15, 2016, 10:55:24 AM Bitcoin Core version 0.12.1 is now available from:
https://bitcoin.org/bin/bitcoin-core-0.12.1/ This is a new minor version release, including the BIP9, BIP68 and BIP112 softfork, various bugfixes and updated translations. Please report bugs using the issue tracker at github: https://github.com/bitcoin/bitcoin/issues Upgrading and downgrading How to Upgrade If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux). Downgrade warning Downgrade to a version < 0.12.0 Because release 0.12.0 and later will obfuscate the chainstate on every fresh sync or reindex, the chainstate is not backwards-compatible with pre-0.12 versions of Bitcoin Core or other software. If you want to downgrade after you have done a reindex with 0.12.0 or later, you will need to reindex when you first start Bitcoin Core version 0.11 or earlier. Notable changes First version bits BIP9 softfork deployment This release includes a soft fork deployment to enforce BIP68, BIP112 and BIP113 using the BIP9 deployment mechanism. The deployment sets the block version number to 0x20000001 between midnight 1st May 2016 and midnight 1st May 2017 to signal readiness for deployment. The version number consists of 0x20000000 to indicate version bits together with setting bit 0 to indicate support for this combined deployment, shown as “csv” in the getblockchaininfo RPC call. For more information about the soft forking change, please see https://github.com/bitcoin/bitcoin/pull/7648 This specific backport pull-request can be viewed at https://github.com/bitcoin/bitcoin/pull/7543 BIP68 soft fork to enforce sequence locks for relative locktime BIP68 introduces relative lock-time consensus-enforced semantics of the sequence number field to enable a signed transaction input to remain invalid for a defined period of time after confirmation of its corresponding outpoint. For more information about the implementation, see https://github.com/bitcoin/bitcoin/pull/7184 BIP112 soft fork to enforce OP_CHECKSEQUENCEVERIFY BIP112 redefines the existing OP_NOP3 as OP_CHECKSEQUENCEVERIFY (CSV) for a new opcode in the Bitcoin scripting system that in combination with BIP68 allows execution pathways of a script to be restricted based on the age of the output being spent. For more information about the implementation, see https://github.com/bitcoin/bitcoin/pull/7524 BIP113 locktime enforcement soft fork Bitcoin Core 0.11.2 previously introduced mempool-only locktime enforcement using GetMedianTimePast(). This release seeks to consensus enforce the rule. Bitcoin transactions currently may specify a locktime indicating when they may be added to a valid block. Current consensus rules require that blocks have a block header time greater than the locktime specified in any transaction in that block. Miners get to choose what time they use for their header time, with the consensus rule being that no node will accept a block whose time is more than two hours in the future. This creates a incentive for miners to set their header times to future values in order to include locktimed transactions which weren’t supposed to be included for up to two more hours. The consensus rules also specify that valid blocks may have a header time greater than that of the median of the 11 previous blocks. This GetMedianTimePast() time has a key feature we generally associate with time: it can’t go backwards. BIP113 specifies a soft fork enforced in this release that weakens this perverse incentive for individual miners to use a future time by requiring that valid blocks have a computed GetMedianTimePast() greater than the locktime specified in any transaction in that block. Mempool inclusion rules currently require transactions to be valid for immediate inclusion in a block in order to be accepted into the mempool. This release begins applying the BIP113 rule to received transactions, so transaction whose time is greater than the GetMedianTimePast() will no longer be accepted into the mempool. Implication for miners: you will begin rejecting transactions that would not be valid under BIP113, which will prevent you from producing invalid blocks when BIP113 is enforced on the network. Any transactions which are valid under the current rules but not yet valid under the BIP113 rules will either be mined by other miners or delayed until they are valid under BIP113. Note, however, that time-based locktime transactions are more or less unseen on the network currently. Implication for users: GetMedianTimePast() always trails behind the current time, so a transaction locktime set to the present time will be rejected by nodes running this release until the median time moves forward. To compensate, subtract one hour (3,600 seconds) from your locktimes to allow those transactions to be included in mempools at approximately the expected time.

The bitcoin core folks are really hard workers, and they always put their code where their mouth is. Congratulations to bitcoin, we are progressing forward to innovation!

Did you not know that LN is evil because it destroys a 2 MB block size limit in terms of performance? ::)Title: Re: Bitcoin Core version 0.12.1 released Post by: OmegaStarScream on April 15, 2016, 01:43:43 PM Is it me or this new version came out fast then the usual updates ?
anyone know when the "Segregated Witness" thing is going to happen btw ? I know that something is supposed to happen this April and the block thing on next year ? or july ? can't remember.

Yeah, there was a really fast turnaround for this release. Instead of waiting a week after the rc2 release, we only waited a few days. Then it was also tagged and had enough gitian builds in a few hours after that so it was a very fast release.anyone know when the "Segregated Witness" thing is going to happen btw ? I know that something is supposed to happen this April and the block thing on next year ? or july ? can't remember. It should be happening later this month or early May. It should be the 0.12.2 release and hopefully that will have just as fast a release as this one.Title: Re: Bitcoin Core version 0.12.1 released Post by: OmegaStarScream on April 15, 2016, 02:17:19 PM Is it me or this new version came out fast then the usual updates ?

I will use it now :) hope there's no bugs.

I have no idea how they exactly plan on "measuring" it.they should create 2 new versions of core the sole purpose of this new version to signal their readiness for 2MB blocks, or signal their opposition for 2MB . miners can use the BIP9 block version number for users we count the number of nodes updated to the latest version of core that is FOR 2MB and the ones Against it..

For sure it's not "calculated" by talking to 4 miners and a few companys, create a timeline and then tell everyone else to suck it. They told to those 4 miners that they will release a segwit scaling solution before the halvening. But they failed. We will go into the halvening without a capacity increase. Stupidity in perfection.

Title: Re: Bitcoin Core version 0.12.1 released Post by: Lauda on April 15, 2016, 03:17:45 PM They probably mean that they will be using a high threshold for activation and reaching that threshold means that a lot of miners will need to support the increase (and though them the community). In addition to having a long grace period (which is what is very wrong with Gavin's BIP). Yeah, that could be it. I am a bit curious about the exact contents of the proposal. IIRC it was <3 months after Segwit code release.Title: Re: Bitcoin Core version 0.12.1 released Post by: Zarathustra on April 15, 2016, 03:22:23 PM I'm not sure how this "community support" is calculated exactly?

It seems that you are the one that has no idea what he is talking about. Again, says who? That is your opinion that it should have been released in April. Yes, they are a little behind schedule, but that is for a good reason. The code is being thoroughly tested and what bugs that have been found have had to be fixed before any release could be made. The testing process takes significant time and energy, and with the changes that have been made for BIP 9, 113, 68, and 112 and for segwit, a lot of testing and code review takes time to make sure that it is perfect.Title: Re: Bitcoin Core version 0.12.1 released Post by: tuvok007 on April 15, 2016, 07:26:46 PM I"we deleted whole blockchain from my hard drive and now I will download the whole thing again.

It was completely irresponsible to sell it as a faster scaling solution than a simple hard fork first before the halvening. We knew it and it's happening now.

The estimate for code release was April, so there are 15 more days to go. Zarathustra is just one of those 'users' that attack Core from any angle.Will this version 0.12.1 be faster in downloading blockchain/synchronizing ? No. 0.12.0 and 0.12.1 should sync equally.Title: Re: Bitcoin Core version 0.12.1 released Post by: achow101 on April 15, 2016, 08:39:07 PM Technically, they aren't.

Heh, well Cyrus isn't someone who works on Core (at least, not that I know of), he just posts these announcements because no one on the core dev team does.I am currently using electrum but thinking to move to new bitcoin core. The latest versions are kinda fast, it does depend on your computer though. Since 0.10, the sync speed has increased and with some other upgrades, it has gotten slightly faster.

I've managed to sync my node within 17 hours on a older dual core CPU and HDD (using default settings). I'd say that this quite the achievement considering the previous synchronization times.

Just another 18-24 months could make a huge difference in perception of how much of a burden it is downloading the ~75GB blockchain. "Fibre to the premises" domestic connections and 4G/LTE cellular networks are still in a state of low rollout across the areas where Bitcoin use is popular. And once regular people in those places consider FTTP/LTE as normal, they'll be saying "100GB? That'll take a few hours, but I guess it might be worth it". Title: Re: Bitcoin Core version 0.12.1 released Post by: vinaha on April 17, 2016, 10:44:12 PM I just want to point out (I don't think it's been mentioned in this thread) that for upgrading you don't need to synchronize the whole blockchain again. It uses the blockchain files you already had before updating.
Title: Re: Bitcoin Core version 0.12.1 released Post by: shorena on April 18, 2016, 10:25:22 AM The current number of nodes is perfectly fine, but why do you think that "regular users" cant run bitcoin core? Well, I would say that the 'average user' can't bother with downloading so much data in addition to the constant need to sync and waiting when opening the wallet. I know a lot of people but only a few use Core like myself.In this case youtube or netflix isnt for the 'average user' either. Anyway, I was hoping for a statement of thejaytiesto since they seemed to have something in mind that should be done. Title: Re: Bitcoin Core version 0.12.1 released Post by: Lauda on April 18, 2016, 11:00:18 AM In this case youtube or netflix isnt for the 'average user' either. I disagree. You don't have to wait for any types of synchronization time nor wait while loading the videos (unless you have a really bad connection). Anyway, I was hoping for a statement of thejaytiesto since they seemed to have something in mind that should be done. I don't see much that can be done though. Even if Core added a SPV mode it seems rather redundant as there are a few SPV wallets as well. Title: Re: Bitcoin Core version 0.12.1 released Post by: Mikestang on April 18, 2016, 07:46:59 PM Anyone using XP and know if 0.12.1 fixes the crashing issue present in 0.12.0?
The problem is XP. There are known problems with 0.12 with XP. See https://github.com/bitcoin/bitcoin/issues/7674 and https://github.com/bitcoin/bitcoin/issues/7639. However i don't think it will be fixed since XP support from Microsoft has ended and thus fixing an XP only problem is not worth it to the core devs. See https://github.com/bitcoin/bitcoin/issues/7681 for the discussion about that. So v0.12 is a total bust for me. It crashed once more and I cannot get it to start up no matter what. It sometimes makes it to "checking addresses" on the loading screen, but never any further. Sometimes it crashes as soon as the loading screen appears. I went back to 0.11.2 and it loads just find so it is a bug specific to 0.12. Here are a few of my logs from the crashes, you can see the program just stops with no indication of any sort of error.

Why even run a node on XP? I know, I understand, it was also my favorite OS for awhile. But a carefully customized Win 10 works even better on the same hardware, and all the linux guys will tell you the same thing about their favorite distro.Title: Re: Bitcoin Core version 0.12.1 released Post by: Mikestang on April 27, 2016, 11:17:07 PM Why? Because when I built that computer Vista was the newest OS and I stuck with XP, and I stuck with that machine for years and years since. :)
Windows 10? Never, never never ever. I would rather not own a home computer than use Windows 10. Linux will be my next OS. We already don't have enough full nodes, I wonder how many of the ones we do have are run on a XP box? Maybe not too many as I see that most nodes have upgraded to 0.12.x already. Title: Re: Bitcoin Core version 0.12.1 released Post by: Dabs on April 28, 2016, 01:09:53 AM I'm on Windows 10. Full node. It's not so bad once you make it behave. (Or you could run it from a VM.) I like 10 better than 7 or 8.1. I stuck with XP for the longest time, then switched to 7 a couple years ago. Now I just skipped 8 and 8.1 and went straight to 10.
Of course, I just use the OS, all other work and stuff are "third-party" apps. Title: Re: Bitcoin Core version 0.12.1 released Post by: 18xk5oT2rLrAc24SL96XT14BX on May 02, 2016, 03:22:59 PM Bitcoin Core version 0.12.1 is now available from: yes The bitcoin core folks are really hard workers, and they always put their code where their mouth is.https://bitcoin.org/bin/bitcoin-core-0.12.1/ This is a new minor version release, including the BIP9, BIP68 and BIP112 softfork, various bugfixes and updated translations. Please report bugs using the issue tracker at github: https://github.com/bitcoin/bitcoin/issues Upgrading and downgrading How to Upgrade If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux). Downgrade warning Downgrade to a version < 0.12.0 Because release 0.12.0 and later will obfuscate the chainstate on every fresh sync or reindex, the chainstate is not backwards-compatible with pre-0.12 versions of Bitcoin Core or other software. If you want to downgrade after you have done a reindex with 0.12.0 or later, you will need to reindex when you first start Bitcoin Core version 0.11 or earlier. Notable changes First version bits BIP9 softfork deployment This release includes a soft fork deployment to enforce BIP68, BIP112 and BIP113 using the BIP9 deployment mechanism. The deployment sets the block version number to 0x20000001 between midnight 1st May 2016 and midnight 1st May 2017 to signal readiness for deployment. The version number consists of 0x20000000 to indicate version bits together with setting bit 0 to indicate support for this combined deployment, shown as “csv” in the getblockchaininfo RPC call. For more information about the soft forking change, please see https://github.com/bitcoin/bitcoin/pull/7648 This specific backport pull-request can be viewed at https://github.com/bitcoin/bitcoin/pull/7543 BIP68 soft fork to enforce sequence locks for relative locktime BIP68 introduces relative lock-time consensus-enforced semantics of the sequence number field to enable a signed transaction input to remain invalid for a defined period of time after confirmation of its corresponding outpoint. For more information about the implementation, see https://github.com/bitcoin/bitcoin/pull/7184 BIP112 soft fork to enforce OP_CHECKSEQUENCEVERIFY BIP112 redefines the existing OP_NOP3 as OP_CHECKSEQUENCEVERIFY (CSV) for a new opcode in the Bitcoin scripting system that in combination with BIP68 allows execution pathways of a script to be restricted based on the age of the output being spent. For more information about the implementation, see https://github.com/bitcoin/bitcoin/pull/7524 BIP113 locktime enforcement soft fork Bitcoin Core 0.11.2 previously introduced mempool-only locktime enforcement using GetMedianTimePast(). This release seeks to consensus enforce the rule. Bitcoin transactions currently may specify a locktime indicating when they may be added to a valid block. Current consensus rules require that blocks have a block header time greater than the locktime specified in any transaction in that block. Miners get to choose what time they use for their header time, with the consensus rule being that no node will accept a block whose time is more than two hours in the future. This creates a incentive for miners to set their header times to future values in order to include locktimed transactions which weren’t supposed to be included for up to two more hours. The consensus rules also specify that valid blocks may have a header time greater than that of the median of the 11 previous blocks. This GetMedianTimePast() time has a key feature we generally associate with time: it can’t go backwards. BIP113 specifies a soft fork enforced in this release that weakens this perverse incentive for individual miners to use a future time by requiring that valid blocks have a computed GetMedianTimePast() greater than the locktime specified in any transaction in that block. Mempool inclusion rules currently require transactions to be valid for immediate inclusion in a block in order to be accepted into the mempool. This release begins applying the BIP113 rule to received transactions, so transaction whose time is greater than the GetMedianTimePast() will no longer be accepted into the mempool. Implication for miners: you will begin rejecting transactions that would not be valid under BIP113, which will prevent you from producing invalid blocks when BIP113 is enforced on the network. Any transactions which are valid under the current rules but not yet valid under the BIP113 rules will either be mined by other miners or delayed until they are valid under BIP113. Note, however, that time-based locktime transactions are more or less unseen on the network currently. Implication for users: GetMedianTimePast() always trails behind the current time, so a transaction locktime set to the present time will be rejected by nodes running this release until the median time moves forward. To compensate, subtract one hour (3,600 seconds) from your locktimes to allow those transactions to be included in mempools at approximately the expected time.

Armory no longer does the updates as the announcements server which provided those updates is no longer working. Rather you should go to the download for Bitcoin Core on bitcoin.org and download and install Bitcoin Core. Then you should also update Armory and download the latest version from https://github.com/goatpig/BitcoinArmory/releases and install that.Anyway... i dont uderstand how to upgrade if i use Armory Wallet... it should do it for his own but when i click on the upgrade nothing happens.

I wouldn't count on it. The exact issue was never identified; it was simply theorized that it could be related to Qt, but no one is sure of it. 0.13 will upgrade to a newer Qt version, but it is not guaranteed to work with XP.

As I understand from the text, upgrading to 0.12.1 is not mandatory, but highly recommended due to bug fixes, updated translations and softwork. However, the fact also is advised to be considered that the new release is not compatible backward with < 0.12.0 versions, which means if you have any software that uses < 0.12.0, you should be extra cautious with the update and do not just update blindly! Good luck to you! Title: Re: Bitcoin Core version 0.12.1 released Post by: Meuh6879 on July 31, 2016, 04:26:57 PM 0.13 RC2 is ready !
