Bootstrap Bitcoin
Even using a fast computer with high-speed connecting to the Internet it may take days to Bootstrap the Bitcoin Blockchain. The first-time synchronization may seem to take an endless amount of time.
You don’t like to wait? Download the latest bootstrap.dat file, a serialized highly compressed version of the blockchain, to speed up the initialization process.
Instead of loading and verifying each block from the peer-to-peer network, your Bitcoin client can load all this information from a single bootstrap.dat file. After the process has been completed, your Bitcoin client is only loading the remaining blocks using the peer-to-peer network. This helps you to get ready much faster in many usage scenarios.
What’s new
The compression format has been updated to xz which allows the decompression of the bootstrap.dat file while downloading it. If you are an expert you can use system pipes to inject the highly compressed serialized Bitcoin blockchain bootstrap.dat to the Bitcoin initial blockchain load up process.
Importing bootstrap.dat further allows deploying containers with Docker or Kubernetes more fasten and secure using fewer resources because you do not have to fully sync each running instance.
In effect, this means that you get an amazing deployment speed of new Bitcoin nodes. I kindly invite you to share your results…

Note
This download file has about 394 GB size; decompression needs some additional 504 GB. Importing this file needs another ~650 GB. Take care of having enough free disk space available for this task!
Installation
To get things running smoothly keep the Bitcoin Core application closed and follow these steps after having installed the application successfully on your computer system.
Download the latest bootstrap.dat.xz file and uncompress (7-Zip or XZ Utils) the included bootstrap.dat file into your Bitcoin Core application folder:
- Unix/Linux: ~/.bitcoin
- MAC OS X: ~/Library/Application Support/Bitcoin/
- Windows: [User Directory]\AppData\Roaming\Bitcoin (i.e. C:Users\MyUsername\AppData\Roaming\Bitcoin)
Open your Bitcoin Core application and wait until it has “imported the blocks from disk…”. The remaining blocks until “now” will be synchronized via the peer to peer network afterward.
Hint: Current versions of Bitcoin Core require the startup option -loadblock=[path-to]bootstrap.dat to import an external serialized bootstrap. Drop a line in the comment section below, in case you need help.
Feedback
Feedback on success is welcome 🙂
Donation
Hosting this ultra-large file offering a secure, encrypted option to speed-download the latest bootstrap.dat is impossible for me without donations.
To download this file please donate whatever amount is suitable for you.
Recommended donation 10$, minimum donation 1$ (depending on the credit card transaction fees).
After donation you are redirected to your individual download page.
or Download with PayPal
If you are unable to donate for whatever reason, please leave a comment below…
Hint: Please consider donating a reasonable amount higher than your credit card transaction fee. Otherwise, your donation will be blocked from your credit card issuer, because the donation amount has to be higher than your minimum credit card transaction fee which is typically higher than you expect.
Thank you for your support.
Thanks. Very helped.
🙂
Danke!
hoping it helps
Yes. Very helpful indeed. Thank you.
thanks
Thx
thanks
super thanks
Thanks for your Upload, but the date doesnt seems correct. I downloaded your bootstrap.dat and imported it into my bicoin-qt, but i still need to synchronize 38 weeks with the network :-/
Florian, are you sure you’ve completely downloaded the latest bootstrap file from 2015-06-23? Did you check the md5 sum of the file after downloading? Take care that you need plenty of free disk space for downloading the file, decompressing and importing the full bootstrap into Bitcoin-Qt.
Pingback: Bitcoin Bootstrap.dat July 2015 | bitcoinspace
Thank you very much for this. I’ve only been able to find the bootstrap anno 2013/14 until now. I’ve referred my visitors here for your updated bootstrap.
https://bitcoinspace.wordpress.com/
Hey guys,
I’ve updated the bootstrap file to Aug 04., 2015.
Hi you last bootstrap have problem to extract. i think zip file is corupt.
Hi Alex,
on my first test run I had the same problem using the OS included tools. Guess the problem is related to the very large file size. I was able to decompress the file successfully using the free tool 7-zip however. Can you please retry if this works for you, too?
i run it under OS X. but you right maybe the large file size is the problem. i try it again now
Please retry another (free) tool like 7-zip if you’re running OS X. I can confirm that trying to unpack the file using OS X generates an error. Maybe that’s an OS X bug trying to uncompress zip files with more than 32 GB size.
It works flawless using the free tool 7-zip to uncompress the file on OS X.
Thanks! Saved me a lot of time.
worked with 7xzip 🙂
Hi dude,
thanks for that sharing. However, It’s pretty slow to download your ZIP. It would be much better to have a torrent version of it.
Best regards.
Hey Kursion,
thanks for your feedback. You’re welcome to publish the file via Torrent after download.
At the moment I’m creating the bootstrap.dat file out of my current Bitcoin-Qt blockchain from time to time manually on my notebook and upload it to my webpage – usually after a user has transferred a donation for this service as a kind reminder for me 😉
This website has quite some reasonable access speed, so you should be able to download this file with a fast speed if your Internet access has no access restriction and if your Internet provider has good and stable international uplinks.
In case someone is (or you all together are) willing to place a large donation (~8-12 BTC) I’m willing to setup a dedicated virtual machine which will be creating a current bootstrap.dat copy of the full Bitcoin blockchain file once a day (or once a week) automatically using a cronjob. On a dedicated machine I can also add an additional download option using Torrent in case this feature is requested.
As the full blockchain has a significant size already, this may be a pleasure for all Bitcoin users out there which rely on the full blockchain information.
Hi, i have created a torrent that can be found here: https://bitcointalk.org/index.php?topic=1310261
I was at 80 percent and you have suddenly deleted the bootstrap.dat zip-file – what a pity !!!
When will the current one be ready?
Best,
Reinhard
Due to size restrictions, my wordpress webspace currently only supports saving one complete version of the blockchain.dat (zip file) for download. Please wait a few hours until my client has uploaded the new blockchain containing all blocks up to #387755 (10. Dec. 2015) successfully.
Keep in mind that this service consumes massive bandwidth. Please donate if you can to support this service staying free of charge for every Internet user!
the new bootstrap blockchain file containing all blocks up to #387755 (10. Dec. 2015) is ready for download.
Unable to extract with 7-zip(x64). Please can you tell the compressor you use for compressing so I can use the same to extract.
Thank You
Kilstag,
have you checked the md5 sum of your local bootstrap.dat.20151210.zip file after download?
I’m also using 7zip but I’ve used the basic deflate compression algorithm to ensure maximum compatibility. What’s your error error message trying to decompress this heavy file?
Nice, thank you. I’m getting insane speeds.
Yes – I know 🙂
Please don’t forget to donate some mBTC for my traffic bill…
Hi,
Just wondering if you want to collaborate in uploading & hosting the bitcoin blockchain. I have set up 2 seed nodes for the blockchain, it would be great if you could also use your server as a seed node aswell instead of a ftp/http download link.
Here is my btc thread: https://bitcointalk.org/index.php?topic=1310261.msg13412319#msg13412319
Hey guys,
Doesn’t seem to Work for me.
What am I doing wrong…?
Its decompressed and in the right folder.
Recent size is 52.47gig.
Still Bitcoin Qt needs to synchronize 2 years and 37 weeks…
Hey Vince,
what version of Bitcoin-Qt and what OS are you using?
Did you take care that your data directory is empty except your wallet.dat and the bootstrap.dat downloaded?
Hint for Mac OS X users: I recommend to use Keba to uncompress the 7z file: http://www.kekaosx.com
Donated twice now from two different browsers. Just times out. No download provided. Any chance you could send me a link.
Hi Warrren,
thanks for sending your feedback. I’ve send you an email.
Is this the pruned chain or the full chain?
I attempted to load the chain using Bitcoin J. When I tried getting the transactions of block # 2 (https://blockchain.info/address/12c6DSiU4Rq3P4ZxziKxzrL5LmMBrzjrJX) it only returned the first transaction ( 0e3e2357e806b6cdb1f70b54c3a3a17b6714ee1f0e68bebb44a74b1efd512098 ) but no other txns.
Is it because the chain is pruned or because of a bug / issue in BitcoinJ? I’m assuming the former, but would like a confirmation.
It’s the full block chain of course.
Did you get any error (or debug) message while Bitcoin J reads the bootstrap.dat file?
Hmmm… donated and get an error page when attempting to download after making donation. …..
Hi Mike,
I did not receive any donation, today.
But hey – don’t worry. It’s christmas time. I’ve send you an email with the download link.
Happy New Year
i can not donate you, i don´t own a a debit card
I’ve send you an email with the download details.
Happy new year! 🙂
Thanx)
Thanks. Very
I just donated, but then got redirected to a HTTP 500 error page.
It would be much appreciated if you could send me a download link.
Hi Jonathan,
I did not receive any donations the last four days. Maybe the payment api is broken. Which error message did you get from which server trying to place “any” donation?
Thx. for your feedback.
Hi, I donated to the link but I received an error when I tried to download. Please help!
Thanks!
What’s your payment id?
I did not receive any donation from your email address, yet :-/
Thanks very much!
Thank you!
Thanks!
thanks
thankyou!
Donated but got no link. Please send link to my e-mail.
Claudia,
do you have the date of your donation on your fingertips?
I did not receive any donation around 1-26. After any donation you should be automatically redirected to the download page with the correct URL.
can i donate with bitcoin?
I’m currently preparing a new blockchain download file with a bitcoin payment option. Please hold on a few days, please 🙂
Dude it would be sweet if you could let loose that Nov blockchain via torrent and link it here…
Hi,
you are welcome to publish a Magnet of the Nov blockchain replying to this post.
I do not one that is the point! I would be forever greatful 🙂
???
Sorry, I forgot a word…
I don’t have the torrent or any magnet links to it, hence the request.
It would be sweet if you could link it here!
Hey flo,
Just made a donation of $3, but when I click on the download link it says the server can’t be reached, hoping this is just temporary.
Hi Dominique,
yes – you are right. Thank’s for the hint. I’m sorry for the outage.
Seems that since a few days the ceph storage of the vps went down multiple times :-/
Can you please retry to download the file? Sorry for the inconvenience.
Hey again Flo,
Thanks for the reply. Just tried, afraid it isn’t working still. The error I get in chrome is ERR_CONNECTION_REFUSED
Hi Dominique,
did you receive my email with the new download page link?
Otherwise you are welcome to proceed downloading the old November file. Once more I had to restart the webhosting service hosting the November file.
Yes, I got it, went into spam, but found it. Links seem to be working now. Thanks a lot 🙂
Thank!!
Is there a way to get the blockclain without paying? I can’t donate bitcoin without access to my bitcoin wallet.
sorry, due to hosting costs providing this ultra large file download does not work without donations. Saving download time and transfer resources on your side may be worth it 🙂
I just donated and I just got an error message, no download.
Hey John,
I did not receive any donation from your contact. Can you please share your error message or maybe a screenshot why it fails for you?
I got error connection refused also in chrome and I already donated.
Please send me the link.
Hi Kettan,
Can you please share your error message or a screenshot? I did not receive a donation from your contact.
transaction seems to fail and a white screen is displayed.
reloading captcha button gives 403 error too.
Hi Bastian,
cc payment is using an external stripe payment interface. Do you have JavaScript disabled? Can you please share a screenshot for debugging?
very usefull data
Hi,
Thanks for providing blockchain bootstrap.
I Donated ~5 EUR with bitcoin, got the download page and started downloading. Unfortunately it was a bit slow (Didn’t want to climb above 2.0 MB/s. Quite fast normally, but for ~60GB file, and for 5 EUR, I’d expect it a bit speedier, since I’m spoiled by usually getting 5-8 MB/s 😉 but no big deal ), got to a bit over half-way, and I think my computer went to sleep. Unfortunately, I can no longer access the download to restart/resume — even if I use the url suffix “#someID” that I was redirected, I still get the page that I haven’t donated. Is it possible to receive a new link? Let me know in email if you need any other details.
Thanks!
Hi Black,
thanks for your feedback. Don’t worry. I’ve send you an email. You can download or resume the file whenever you want.
Did you use the Bitcoin api for donation? With about 45ms packet roundtime the Download should run much faster than 2.0 MB/s for you. What’s the Internet speed you pay for?
Donated but took me to blank page with no download link
Mohsin,
did you donate using CC or Bitcoin?

Can you send to me archive instead of bootstrap.dat? I need archive with folders CHAINSTATE, INDEX and files blk00784.dat-blk00789.dat and rev00784.dat-rev00789.dat (or newer). It will be 2-5 GB instead of 60+ GB
Xander,
I’m already using Bitcoin Core v0.14.0rc3.
/chainstate/ now contains (dot)ldb files.
blk?????.dat and rev?????.dat files are content of /blocks/.
If you think it helps I can share an archive containing the files blk00784.dat-blk00789.dat and rev00784.dat-rev00789.dat (or newer).
Your Bitcoin Core client should verify the blocks on import and create the chainstate files itself. At least it does using the bootstrap.dat file…
I can install Bitcoin Core v0.14.0rc3. Successful synchronization is enough for me the last 6 (I hope) blocks (blk00784.dat-blk00789.dat and rev00784.dat-rev00789.dat) plus all data from folders CHAINSTATE and INDEX. If you can then share this for me. I will be happy.
Xander,
I’ve uploaded you the files desired:
Please give me a small hint if it worked for you.
Yes. It was successfull. I save debug.log if you interesting http://dropmefiles.com/UMAYJ
thank’s for help
Hi!
What you are doing is awesome. My core wallet shows me months to finish download! I can´t donate because I dont have a CC and, well, my btc are in a wallet that needs the blochckain. I accidentally deleted it while switching laptops not knowing how long it would take to re download 🙁
Do you plan to update the file anytime soon?
Could I donate after downloading the file and unlocking my btc? boy scout word!
And also, is it possible to download the file in different intervals? (e.g. only during the night)
best!
I’ve send you an e-mail.
Hey,
Thanks for your work, mate, very appreciated, but I’m confused. I’ve downloaded the blockchain recently, I want to do it again and… I can’t? My download hangs every time I retry.
There is something wrong with the download server? Or I’m just missing something?
Of course, I made a donation the first time.
Thanks for answering!
Hey Kashi,
thanks for your donation. Of course you can download the blockchain again whenever you like. I’ve send you an email with the details.
Hi flo,
I donated via CC but there is only a blank page afterwards. Maybe you can send me a link over E-Mail.
Thanks and best regards,
Mark
Hi Mark,
can you please share some details about your donation? I did not receive any donation on 03/12. Did you try paying with CC or BTC?
Hey dude,
I cant donate unfortunately due to my country 🙁 , can u send me the link to my email?
can you share some details why you are unable to place a payment from your country and about your setup to combat censorship?
download?
do you have any issues trying to download a copy of the blockchain?
Hey,
I’ve received an unrecognised bitcoin donation today. If you failed to download the blockchain with that payment please leave me a note here with your exact btc payment amount.
If it matches I’m going to contact you via e-mail to resolve this issue.
Thanks
I am jobless. I can not give you anything. Thank you.
where are you from?
Basque Country.
Nice place.
thanks you
Thanks!
Donated, but did not get a link to the file. Page is blank after donation.
Please send link to my e-mail.
Thanks for the hint and sorry for the inconvenience.
I’ve received your donation and send you an email with the download link.
What browser and (security related) plugins are you using?
Do you have the URL of the blank page?
thanks
thx dude!
Hello, the archive is broken. Have 2 times tried it with 7 zip to unzip. Come 2 errors.
Best regards
Windows 7
Hi Hartmut,
can you please check if the the signature of your downloaded file matches the signature of the download page?
What version of 7zip are you using on Windows 7?
How much free disk space do you have available on your system (and disk)?
Hartmut,
I’ve just downloaded und extracted bootstrap.dat.20170120.7z on a new vps. It works like a charm with max vps io speed.
Please cross-check the signature of the downloaded file.
Hello Flo, I downloaded the bootstrap.dat.20170120.7z yesterday about your site and unpacked with 7 zip version 16.04. Unfortunately always 2 errors. Sorry for my english. Google translator
Hartmut,
as far as I know the Bitcoin blockchain contains signatures of known viruses:
Is it possible that your antivirus engine is blocking the download or unpacking of the downloaded file?
What error message do you get trying to unpack the 7 zip archive?
I’m currently working on providing an updated serialized blockchain allowing to unpack the compressed bootstrap.dat-file while downloading it.
I’ll let you know on this page as soon as it is available for download.
Скачал, всё пучком!
Спасибо и повеселиться
I made a small donation just to confirm that I could get the link and the page went blank. Can you send the link by mail? Thank you!
Hey João,
I did not receive any donation on 2017/05/18. When did you donate what amount?
Wish I could have had this way back when I first tried mining. Just getting back into mining again.
Donated, but did not get a link to the file. Page is blank after donation.
Please send link to my e-mail. Thanks!
Hey Gary,
do you have another unfiltered e-mail address? Every time I try to send you an e-mail message I get the following error message:
2001:0df6:f400:0000:0000:0000:0000:2808 failed after I sent the message.
Remote host said: 550 Mail content denied. http://service.mail.qq.com/cgi-bin/help?subtype=1&&id=20022&&no=1000726
You are in China? Can you try if the following (temp) URL works for you?
bootstrap.dat.xz
Hey Gary,
thanks for your hint!
Based on your feedback I have modified the download URL after payment. Now it does no longer contain the word bitcoin.
Hopefully this step helps all of you living in countries with restrictive internet access.
Please let me know if you are now able to downloading this mega file – or – if you like me to refund your cc donation.
Hi, i can download now, will download it from server, still need hours..Please don’t delete the file for now. Thanks!
Hey Gary,
did everything work for you?
Thx
thx for hosting
Thank you for your explanation on how to speed up Bitcoin QT.
testing pbtc
i donate you 0.6$ with cc.plese give me link
Hi bogdan,
thanks for your feedback. When did you donate 0.6$? I have not received a donation of this amount yet, today.
After donation you should be auto-redirected to the download page. Did you get any error message after payment?
my english is so bad.redirecting is not,but i donated 0.6$.Did it error?
It seems to me that your credit card donation failed. Maybe a security related issue.
I’ve send you an email.
oO ths bro
Can i have the download links
thx
Cool
Thank you !
hi, again.
I’ve downloaded the Zip file, extracted it with 7Zip to a portable harddisk, where the bitcoin core foler is, I’ve tried it in the blocks folder and the core folder but neither works and it continues to show that it has to sync the all the blocks.
My bad the sync last about 10-15 seconds then the window dissapears and shows that all is synced, still dont understand why it start with this sync and from the beginning of it.
But now ne more time that I close and open Bitcoin Core it starts to sync from the beginning…I’ve got to wait several minutes and it shows that it is synced…is that normal
Bitcoin Core should load/import the bootstrap.dat file once and after this step completes it should be renamed automatically by Bitcoin Core.
Trying to download now, when successful obviously I will send a donation! 🙂
Couldn’t download without the donation 🙂 So donated and now it’s downloading. Thanks, hope it works!
Sure it does. 🙂
Let me know in case of any issues.
Since this file is so large, can you make it available for FTP download or something? I have a pretty robust internet connection and it’s still saying 12 hours to download. Seems like FTP or torrent would be more efficient.
free to download here https://bitcointalk.org/index.php?topic=1310261.80
thank you
Hi i donated 2 times but couldn’t redirect to the download page. How can we solve this?
Hi Vanalon,
I did not receive any payment on 06/30. How did you donate? CC or Bitcoin?
Please give me acc in Brasil for link, sorry no speak english, muitchá graças for brazil
thanks
Hi Flo,
I donated two times today (2017-07-14) by CC, but redirect link failed:
– Firefox: empty page
– Chrome: error 500
Please reply to me by e-mail directly.
Thanks
Johannes
Hi Johannes,
I’ve updated the blockchain and the cc payment plugin two days ago.
Can you retry if it works, now?
Thanks
Hey guys,
I have received an unrecognized bitcoin donation a few minutes ago.
Please contact me or reply to this thread if you are the unknown user who made the donation.
Thank you!
Hi, I have just donated and the link I was referred on returned an error..
Hi Issa,
I’ve send you an e-mail to resolve the issue. I did not receive your donation on 07/24.
thanks you
thanks you
this is amazing
paid with bitcoin but didn’t show me for 2 hours that the transaction has been finished. it just stays and says Awaiting payment from you….and rotating from 2 hours..
confirmed. I’ve send you an email with the download details.
Anyone donating BTC: Please take care and donate the exact BTC amount only, otherwise the plugin fails to auto-confirm the transaction.
got nothing in my mail bro?!
I’ve just resent the email one more time. Please also check your spam folder. Maybe the email is filtered because it is containing a link.
worked out. thanks!!
Hi again , it downloaded 53Gb and stopped downloading, did you cut it off somehow or is the actual size of the file 53Gb?
thank you for your time!
Ive started to download the file once more, hopefully it works out.
Letting u know if u wonder who it is
Thanks!
I am new to cryptocurrency and do not have the available funds to donate, will donate once I am able. thank you for providing bootstrap.
Hi Blocco,
as a newbie Bitcoin user (with no funds) I recommend you to download and start the wallet application of your choice and to let the application load the needed blockchain data directly from the p2p network. It’s free and it is the recommended way to get your installation ready for the majority of usage scenarios.
This serialized and highly compressed bootstrap.dat.xz download is recommended for professional use to speed up the initialization process (and to lower the bandwidth and ressource demands) in some usage scenarios. The donations are used to cap the hosting costs needed to be able to prepare and offer such a huge file for direct download.
What’s your planned setup or usage scenario?
Dude, you said to donate any amount. Why is btc not accepting my donation?
Hi Renny,
check your email. Donate any amount only works using CC.
Using BTC, please take care and donate the exact BTC amount only. Otherwise the BTC plugin fails to auto-confirm the transaction.
In general: If you like to donate a higher amount please split your donation into two transactions; one with the exact amount and another with the additional value.
Entered CC data, but not redirected to download page. Please advise.
Hi Todd,
I did not receive any CC donation, yesterday. What error message did you got?
it would be counterproductive to do this manually…. as counterproductive as the web scraper I tried today on a website.
Hi Boggd,
I’m not used to web scraper so I’m unable to evaluate this product.
For sure a highly compressed, serialized bootstrap.dat file is useful in some scenarious.
It helps you to save bandwidth, because you only need to download about half of the size compared to the uncompressed blockchain download from the p2p network. And it needs less computing ressources on import because the blocks are already serialized which also speeds up things slightly.
If you have to deploy multiple nodes you don’t like having all nodes to download the complete blockchain which would be an enormous waste of ressources.
The import of this bootstrap.dat speeds up deployment time incredibly for me.
I can download the file once, store it on a fast external media and use it to deploy multiple installations with insane speed. Even those suffering poor Internet access.
Thanks offering this service!!!
Thanks mate. I appreciate.
Hi again!
I downloaded the 80Gb zupped file, unzipped with 7Zip and moved the file to the diretory of the Bitcoin folder.
However it didn’t work out for several times, the Bitcoin client continues downloading and synching with the web and doesn’t find the bootstrap.
I uninstalled the program several times as well but no success.
What am I doing wrong?
Also when I try to open bitcoin-cli.exe to write a command about the bootstrap location , the bitcoin-cli.exe shuts down itself after some seonds.
Thanks. Very helped.
okok found the AppData folder and thigns are wrking out, but since i’m really a noob with computers , I would be extremely thankful if you can write some detailed description of the process for all noobs out there who wonder how it works
Thanks for your great feedback.
Would it have helped if I provide example installation instructions using video (i.e. on YouTube)?
Or do you prefer screenshots of the installations steps?
awesome will test this
Thanks!
Awesome service!
Perfect date to split up my wallet funds easily into Bitcoin and BitcoinCash.
Thank you!!
Great service!
I can download it fast!
thanks
Well, bad luck for me. First attempt the download aborted after 4 hours, file size 73 GB. Second attempt aborted very quickly, file size 2 GB. Third attempt now running. Pray for me!
Dirk
Third attempt aborted at 12GB
How can I find out why my downloads abort all the time
Dirk
Hi Dirk,
what OS and Browser are you using? If your Internet works connection fine, the download should run without any issues.
Can you try to download the file using a multithread download manager, like DownThemAll! [Firefox Addon] for Firefox?
Hi Flo,
Thanks for responding. I’m using W10 and Chrome. Fourth attempt now running and 35 GB downloaded. I have Firefox but if I copy the URL from the downloadpage in Chrome I’m getting the message that I have to pay (again). What should I do?
Dirk
Hey Dirk,
don’t worry: I’ve send you an e-mail with a direct link in case you have to use another browser.
Thanks Florian,
4th attempt succes, now unzipping!
Dirk
Thanks
Paid 0,50 cents but got forwarded to an server error 500 page.
Please fix 🙁
Hey Tlo,
minimum CC gateway fees are around 0.6$. That’s why any donation below fails.
In order not to feed the CC companies only please tip a reasonable donation if you can. Thx.
hi, success downloading it…but, corrupted while unzipping it…advise please…
did you check the signature after download?
What OS are you using? On Windows please use 7zip for decompression, on Mac OS X I recommend using KeKa.
Remarkable!!! Takes so long for a fresh blockchain download.
superb
Thanks!
is it normal?
Hi Albert,
do you mean the “Cookie error” malfunction of the GoUrl Bitcoin payment api during the last days?
No this is not normal and has been fixed, today.
Just in case: Please drop me a line in case you hit any error on this web page. 🙂
thanks
donated and the link is not working. please fix. thanks

Hi Rod,
thanks for your hint. I had to reinitilize the hosting service hosting the file and now it’s back up running.
Sorry for the inconvenience
Thanks!
Hello, i just made a donation, but did not get redirected to the download. Can you please send me a link?
Hi,
I did not receive a donation from your address. What method did you try to donate?
I donated and I didn’t receive a link. Please email it to me. Thank you.
Hi Travis,
I did not receive a donation for your address. How did you donate at what time?
It isn’t processing my payment. Could you send me a link?
Hi Jenn,
what error message do you get trying to donate?
Thank you for this service!
No have money
what project do you like to push using the boostrap.dat?
Thanks
Thanks so much!!
thanks
cant donate sorry
Hi Bob,
what project do you like to push using the boostrap.dat?
Hi,
I sent BTC to 1dRfuaa…, but I can’t download. 🙁
Ack. I’ve received an email from GoUrl about an unregognised payment (slightly overpaid).
I’ve send you an email.
I changed my mind. If you send me a download link, please send bootstrap before Bitcoin Cash netsplit instead of current bootsrap. Thank you.
Hi T,
thanks for your donation. I’ve send you an email with both download options.
question. I installed bitcoin core on external lacie hard drive. so to install the bootstrap I’m not sure where to put it.
you say “MAC OS X: ~/Library/Application Support/Bitcoin/”
but i have the app and then a separate folder with the files and folders “blocks” “chain state” “database”.
should i just drop the bootstrap in this folder? or do I have to do other things?
Put the file into the folder containing the files and folders banlist.dat, bitcoin.conf, blocks (dir), chainstate (dir), …, wallet.dat and (re-)start the Bitcoin-Qt client afterwards.
It’s possible that you have to rename (or delete) the (sub)directories blocks and chainstate prior to starting Bitcoin-Qt in order to force your Bitcoin-Qt client to reimport the blockchain information using the bootstrap.dat file.
debug.log file should output a line “Importing bootstrap.dat…” if everything is working like it should.
Hi thanks for the effort. I am doing this for research purposes for now and hopefully it will lead to other things. I will donate with paypal if its successfull.
1. I cleaned all the roaming directory except uncompressed bootstrap.dat
2. Bitcoin Qt 0.14.2 doesn’t read it and starts from january 2009
3. I re-cleaned all the roaming directory except uncompressed bootstrap.dat
4. BitcoinABC 0.14.6 doesn’t read it and starts from january 2009
what to do?
Hi mario,
can you please share some details about your setup? like OS (version), Bitcoin installation using default values?

If you did everything correct, debug.log (file) should contain the following line: Importing bootstrap.dat…
Hint:
ok, my debug.log file show the same Importing bootstrap.dat, but the interface shows extracting data from 3 january 2009 the same
so my questions are:
1. is it normal to see interface trying to extract first history blocks?
2. how long I have to wait for the total decompression of bootstrap.dat?
3. is it possible to do same operations for BCC with bitcoinABC wallet?
Thanks
1. yes, it’s extracting the data of the blockchain from the bootstrap file since the first block. Moreover for security reasons it checks the block signatures taking quite some load on the cpu(s). So that’s normal.
2. depends on your system cpu(s) and disk io performance. If you are using a Unix based OS like Linux, Mac OS X or …BSD you can use system pipes to decompress the bootstrap.dat.xz file on the fly. If you are brave you can do it even while downloading the file. That’s very neat for example if you like to push online a Bitcoin node using a cheap VPS with limited disk space (using a pruned blockchain). Awesome feature 🙂
3. Yes, the bootstrap.dat file should also work using Bitcoin ABC. Let me know if you have any troubles.
i had already decompressed bootstrap.dat.xz!
my question was about bootstrap.dat..and if I have to start to decompressing it since 2009 and it’s slow the same, it’s the same downloading it directly by qt!
i hoped that extraction of blocks from bootstrap.dat was immediate-faster, but the “rythm” is the same and damned slow: hours to copy/decompress and further days or weeks to update, also with the problem to free 300+Gb on the HD!
not for me, I resign
Using an up to date system importing the blockchain using a bootstrap.dat file should work within some hours (instead of days).
Does your debug.log contain the following lines?

The import above was running on a Linux VPS downloading and decompressing the bootstrap.dat on the fly using system pipes.
I was using the following commands
mkfifo bootstrap.dat
chown [bitcoind-userid]:[bitcoind-group] bootstrap.dat
wget -O - http://[download-url]/bootstrap.dat.xz 2>/dev/null | /my-path-to/xz-5.2.3/src/xz/xz -d -c > bootstrap.dat 2>/dev/null &
--> start bitcoind
I recommend to delete the (renamed) bootstrap.dat.old fifo file after successful import.
The combination above is very neat firing up a cheap vps (or docker container) with bitcoind running in pruned blockchain mode needing limited disk space only (my recommended minimum: 10gb).
thank you
I’m getting good download speeds from getbitcoinblockchain dot com
getbitcoinblockchain dot com offers to download a copy of the whole bitcoin data blockchain directories (only). I do not recommend to use a foreign dump of these files, because it’s missing every verification process and it includes database junk data.
Importing the blockchain from a serialized bootstrap.dat files offers you the advantage to start with a clean and verified local blockchain copy.
question: after bootstrap.dat become renamed .old, can I shut down and restart the wallet?
I ask you this because the PC is very slow even if CPU and RAM are not so used
Yes, if the import succeeded and your Bitcoin wallet is up to date you no longer need the bootstrap.dat.old file (and the compressed download file). You can delete the files.
my question is intended if it’s ok shut down and restart wallet (of course after bootstrap has been renamed old), because I noticed that first couple of hours PC is ok, after becomes slow…so I’d prefer shut down the wallet and restart many times instead of leaving it many hours running
I hope to have been clear to explain
thank you
mario,
opening “Help” -> “Debug window”.
What’s the current status of “Block chain”
“Current number of blocks” and “Last block time”?
These number should be greater than (or equal to) 485,762 and So. Sep. 17 18:44:58 2017.
If that’s not the case it’s normal that your client is running on high ressource demand because it’s still syncing the blockchain.
current number of blocks: 418031
last block time: 26th june 2016
STARTUP TIME: 14 september 2017 (continuous, still running) =>resources: ALWAYS 10% of less of processor used so 90%+ available , 3Gb ram free and available, BUT BUT BUT it’s terribly slow the same and I don’t know why
so i repeat the question in another way and i hope for last time: if I shut down /turn off the wallet NOW and I restart it, does it restart from the beginning or from the last damned 20Mb about index?? or should I destroy PC let it running until xmas?
last block time: 26h june 2016 means that your Bitcoin client is still doing some resync work on old blockchain data.
Did you import the bootstrap.dat file using this option?
-loadblock=
Imports blocks from external blk000??.dat file on startup
Thanks
I donated but was not given the link.
Sent you a message via the feedback.
thanks for your donation. I’ve send you an email.
thanks
blockchain date and download url has been updated, today.
I’ve send you an email with the new download URL. Thanks for your donation!
can’t donate as of now, but when my btcoin is up and sync i would donate.
check your email, eliza.
I donated but download link gives an error. Please email right link to me.
Sorry, short maintenance of the web service for a few minutes. Please retry.
Hint: I’m just preparing the newest blockchain bootstrap.dat for download.
I just donated but i cannot redownload it anymore?
thanks for your donation. I’ve send you an email with the download details already.
What error message did you got after donation? Do you use any ad-blocker or script-blocker?
I have a scientific interest in the data bitcoin blockchain contains, like how much addresses are used routinely, how much are not, how large daily volume of transactions is and so on.
Question: is bootstrap.dat what I need? how is the data (input/output amounts, adressess) kept in it (encoded?
encrypted?) if the bootstrap.dat is not what I need how can I get the proper dataset (can I?)?
Hi Nikita,
the bootstrap.dat file contains the serialized blockchain of Bitcoin.
So basically it’s like running
getblock [blkhash]block-by-block.What tools are you using for your scientific work to analyze the blockchain data of Bitcoin?
Hopefully you are aware that you need to scope with a large amount of data running analysis on Bitcoin blockchain data.
thanks
down?
what’s not working for you?

Hi flo,
would it be possible to donate via paypal?
Reason being that I do not own a credit card.
BC will only be possible after a resync which of course… you know 😉
Hi furcifer,
thanks for your feedback: I’ll take an eye on this useful feature request on my upcoming website maintenance. 🙂
I have .07 bitcoin
And bitcoin core downloads for almost 2 days now !
I want to donate but i can not send any bitcoin until syc finishes !!!
Can u please send me link i will donate when i get my bitcoins. I hope.
Hello,
I paid for the bootstrap download and the download never finished and will not resume. It is at 18.8gb and it will no longer resume and I cannot re-download without paying again
Thanks for your donation. I’ve send you an email with the download details, so you can resume the download anytime you like.

Did my card get charged now? How do I download the file?
That’s because of the basic CC fees. Donations using less than 1$ usually fail; donating 1$ is like feeding the CC companies only 😉
great service thanks
good
helped a lot
Donated and didn’t get a download link
Hi Jonathan,
sorry – did not get any donation the last hours. How did you donate?
Just did it via CC.
It didn’t work, otherwise I would have received an email with your donation amount. Did you try to donate less than 1$?
Let me try again
Most failed cc donations are caused by donating an amount less than the cc fees of your cc. And these basis transaction fees are mostly higher than you expect them to be…
Thanks for your donation!
i made donate, but not get link
Hey Mikhail,
how did you donate? Did you receive an error message on donation?
debit card, there was turn on 3d secure, but i didn’t enter sms code. i guess charge was’t. Can donate in paypal?
I have added a PayPal interface. You are welcome to give it a try… 🙂
Paid by CC Thursday. No download link?
It appears that CC transaction did not go through. Please confirm and I will try again.
Hi Edward,
I did not receive any donation from you on Thursday. In most cases CC payments fail if the donation amount is below your CC transaction fee.
Thanks!
very help
thnks
thanks
Thank you very much !
Cannot donate minimum through paypal. Malfunctioning integration.
What’s going wrong for you? Paypal seems to work fine here 🙂
Did you try another donation method? Failed payments are mostly due to donation amounts below the payment fees; sometimes due to blocking abuse security algorithms.
brilliant !
thanks maybe
maybe? 😉

Hello, not sure if this is where I should ask, but I donated to download bootstrap.dat and copied the link so I could download at my university library (better connection).
I tired a few times and would get to about 10% when the download would drop to 0mbps.
I checked with IT and we are not throttled and are on an R1 direct line so it’s not on on our end. Is there an IP restriction when donating? I’m happy donate again if that’s the case…
Hi Chris,
thanks for your donation and feedback.
No, at the moment there is no IP or other access restriction active on the download server. I have send you an e-mail with additional information. I’m unable to reproduce this throttle effect. Please give me some more feedback to be able to debug the issue…
donated with paypall, got an error saying link can not be trusted or something like that.
cant try again without donating again 🙁
Hi Bart,
thanks for your donation. I have send you an email with the download details.
Can you please share which security product blocked the download (or the download webpage)?
The Bitcoin blockchain contains some known virus signatures but this information does not cause harm to any Bitcoin client, i.e. https://en.bitcoin.it/wiki/DOS/STONED_incident
To be able to debug this issue: What’s your OS, Browser, AntiVirus, other AddOns/Plugins causing the blockage.
🙂
no money
what no money related Bitcoin project do you like to push using the latest serialized bootstrap file?
Thanks
thanks
and this will give me download link?
Thanks

You are welcome.

Wow! Pay for free stuff? Amazing!
Hi, thanks for this service. I have donated today (few hours ago) but then closed by mistake the page. Any way I can get my personal link back?
thank you
k thx by
Thank you for this resource!
Hi. I have donated money to download the file. When unzipping with 7-zip, I can read error file corrupt 2 errors, in addition when decompressing only occupies 3.3 GB, not 180 GB. Is it normal? If I have to download again, do I have to donate again? Urgent Thank you. (I have windows view)
Hi Felip,
thanks for your donation! Did you check the file signature after download. I guess your downloaded file is incomplete or corrupted. I’ve send you an email with the direct download link.
Let me know if you need any further help. 🙂
tahnks for halp
Thank you !
Thanks for your kindness
Thanks
Thanks
well done
I need 418GB free ???? is this?
I recommend about 300GB free disk space for import using these steps
Hint: To archieve perfect import performance I recommend to decompress the bootstrap file to an external drive, i.e. an USB3 harddisk and to use this external file for import.
How do you import witht the Windows client? Otherwise, what folder do I place the bootstrap file into? I don’t have my bitcoin client on the C: drive, its on a different drive, E:\Bitcoin with the following folders: Blocks, Chainstate, Daemon and Docs. Thanks.
Hey PizDat,
do you have the complete installation of BitcoinCore located under E:\Bitcoin ? i.e. E:\Bitcoin\Bitcoin-Qt.exe ?
What’s your current location of the downloaded bootstrap.dat file? Did you already decompress it?
thanks!
thanks man, great effort!

I “donated” with double spend tool from https://f…io/
Proof: Download link 🙂 https://flo.sh/download-bitcoin-blockchain-with-bitcoin-payment/
Double spending only works if the payment API does not wait until the payment has been mined into the blockchain.
Usually, that’s the case for micro-payments.
Offering a service to fool third-party trusting into unconfirmed transactions for micro-payments is no noble contribution to the community; it’s a shame and would be considered as an illegal activity in my country.
thanks

I cant donate but need that file …
good service

pls, upload only this file?
201035.ldb
Fatal LevelDB error: Corruption: block checksum mismatch: .bitcoin/indexes/txindex/201035.ldb
EXCEPTION: 15dbwrapper_error
error only 30 000 blocks to end syncing 🙁
Hi btcgripe, I guess it won’t help you to copy this file from another client, because every client is maintaining its own database. Did you try to re-import the serialized bootstrap?
I have bitcoin core 0.7.0 in my laptop.
Can I install this or I need to upgrade to latest version first?
Should also work with v0.7.0 because it’s a serialized export of the blockchain.
Thanks
good for me
Спасибо
Спасибо, и вас тоже!
Thank you
Thank you!
I made a donation but cant download pls what now.
Don’t worry. Send you a priv. msg. What error msg. did you got?
Thanks.
Thanks a lot for the upload
thanks baby
Thanks bro 🙂

Gracias por tu apoyo.
Thanks
Thanks
thanks!
It’s unbelievable that Bitcoin Core takes so long to sync but I’m happy that there are people who offer an alternative. I am very happy to donate something as soon as I get my bitcoins back.
Ну и. чо за шляпа? при распаковке выдает что архив битый, архиваторы последние в чем шляпа?
Какой архиватор вы используете? Попробуйте 7zip и перепроверьте контрольные суммы после загрузки, чтобы убедиться, что у вас есть неизмененная локальная копия загрузки цепочки блоков.
Будем пробовать. 5 звезд!
Thank’s!
thanks for sharing
just testing this
Thanks!
was at 80 percent and you have suddenly deleted the bootstrap.dat zip-file – what a pity !!!
When will the current one be ready?
Best,
Reinhard
Hey Reinhard,
the download link does not expire. What’s your error code?
THanks
very cool

Am I mining anything or just wasting time?
I did fill in my address and username with my own information
You have to lookup and/or request this information from your pool provider: https://zpool.ca/
Did you meanwhile receive payouts to your BitcoinCash address for your mining effords?
Ty so much!
Thanks a lot!
Thanks for this!
thanks for this
Thank you for that

Hello, thx . But is not ok :s
My raspbery pi 3 work whith NAS, dans the folder ~/.bitcoin is too small…
I tried in the “datadir” directory but bitcoincore downloaded from zero …
I tried in “folder / blocks” but the same …
same results with Windows…
Thx for your help (by mail ?)
Import can only work, if you have plenty additional disk space available. Please check the requirements.
Hint: Downloading the serialised blockchain to an external media may help to preserve required disk space to be able to load and process the import task(s).
How much disk space do I need on my internal drive? I have over 480 GB on an external, but only 90 GB free on my internal. My internal is only 250 GB total. I’m running on a Mac and encountering the same issue. Part of me is thinking of installing a fresh copy on my external, but I feel that’d take too much effort for something I have no guarantee of knowing it’ll work.
At this point, I’m just going to let the Blockchain sync from scratch. Shouldn’t take much more than 5 days with my connection. Though it would have been nice if I had gotten this working.
CoolGuy,
with only 250GB total on your internal drive I recommend you to run prune mode on your local blockchain not needing a full copy of the Bitcoin blockchain.
On my MacBook I am currently fine with these settings:
cat ~/Library/Application\ Support/Bitcoin/bitcoin.conf
[...]maxuploadtarget=144
prune=28880
Alternatively you can export your ~/Library/Application\ Support/Bitcoin directory to an external drive having 500 GB++ storage available using a standard Link (ln command) but in this case you can only use your local Bitcoin-Qt client while having attached the external drive.
ty
Thanks
I stored my bitcoins on paper wallet (Offline) years ago and since my computer was stolen i need to download the entire blockchain to recover financially. I am unable to donate at the moment.
Tebogo, your case is a great example why it is important to always have a reliable backup. Lucky guy 🙂
Hint: Did you already try to import your paper wallet into a mobile phone blockchain application, like BRD?
Thank you for your service
tnx
thx!
thx

You should consider making this into a bittorrent and more of a community thing instead of an individual needing to ask for donations, although, I suppose torrents should be associated with a torrent-coin. Also needed for monero, litecoin, bitcoin 2, and…..
Tried this out already, but due to the lack of community support it did not succeed. Thanks for your hint about Monero and other popular Altcoins. Will have to automatize the tasks needed to generate the download(s) to get this working.
Your Bitcoin land page says: Invalid Data.
Please fix.
Thanks for your hint, Nunzio. Seems the Bitcoin API provider has gone out of service. Will take care of it.
Nunzio, issue should be fixed. Thanks for your report.
Super Work
Thank you very much this is what I was looking for

Hi! Would love to be able to download
You’re welcome. It’s a fast https secured download.
Funciona mesmo? Não vem mamado?
Sim, claro que sim. Pelo menos se você sabe o que está fazendo.
How do I put it on Umbrel OS. I put it in the bitcoin folder and nothing happens. Do I need to make any commands?
Yes, you need to execute Bitcoin Core (cli) with the option:
-loadblock=[path-to]bootstrap.datHow do you run Bitcoin Core on Umbrel OS? Using Portainer?
Thank you.
thx
