managing bitcoin blockchain
you can send & receive bitcoins using a full node synced bitcoin core wallet
If you haven't installed the bitcoin core wallet please go to Step1.
Step 2. synchronize the wallet with the bitcoin network downloading the bitcoin blockchain distributed ledger
downloading bitcoin blockchain piece by piece
Bitcoin blockchain is saved in a whole of directories and files with this structure (default installation data directories):
Within ../bitcoin/blocks there exists a index subdirectory and files named blk*.dat and rev*.dat that until 20250227_0854am UTC-3 run from 00000 to 04800
Within ../bitcoin/blocks/index there exists files named *.ldb and three ones called MANIFEST-005274, CURRENT and LOCK
Within ../bitcoin/chainstate there exists files named *.ldb and three ones called MANIFEST-3320126, CURRENT and LOCK
Totalizing about 691 GB of data. All of these files are the bitcoin blockchain until 20250227_0854am UTC-3 blocks=885555
how to download 691 GB of data over the internet in a reasonable time
Waiting for a full synchronization of the bitcoin core wallet takes about 3 or 4 weeks depending of your bandwith and computational resources
This site www.blockchaindownload.store have taken a copy of all of this files at some time (until 20250227_0854am UTC-3) and upload to Mega.nz to your download
Once you have all the files downloaded an unzipped in your computer you have to copy and replace all the files provided preserving the right places and structure of the bitcoin blockchain we have shown before:
all blk*.dat and rev*.dat files within ../users/YOURUSER/AppData/Roaming/Bitcoin/blocks
all *.ldb files within ../users/YOURUSER/AppData/Roaming/Bitcoin/blocks/index
all *.ldb files within ../users/YOURUSER/AppData/Roaming/Bitcoin/chainstate
then run the bitcoin core wallet running bitcoin-qt.exe and wait for full sync of the wallet
we organize the files to download in a whole of zip files uploaded to Mega.nz
blk*.dat and rev*.dat files belonging to the blocks directory
blk00000.dat to blk00221.dat are zipped in blk00000_00221.zip and upload and so on
rev00000.dat to rev00221.dat are zipped in rev00000_00221.zip and upload and so on
As a result we have 22 blk*.zip files and 22 rev*.zip files. Please look at the following table
ldb*.dat files and manifest-005274 current and lock files belonging to the blocks/index directory
all the *.ldb and MANIFEST-005274, CURRENT and LOCK files files are zipped in the file index.zip and upload (index.zip zipped size 104.461 MB)
ldb*.dat files and manifest-3320126 current and lock files belonging to the chainstate directory
all the *.ldb and MANIFEST-3320126, CURRENT and LOCK files are zipped in the file chainstate.zip and upload
(chainstate.zip zipped size 10.308 GB)
