I have experience creating blockchain bootstrap.dat files, and
am offering a service to create a bootstrap file for any altcoin.

Examples:
Archcoin - https://mega.nz/#F!UxFGFDyY!sbyQqeLXJtzLh8vuDUKVGQ
Blitzcoin - https://mega.nz/#F!ohFQEDQQ!6OB2S2hP2hh72Mk301M_ZA

Cost: BTC0.01

PM if interested

will give the guide to do it free

dont send me btc or anything,

Go to roaming file.  Find blk0001.dat, copy and paste it elsewhere and rename it to bootstrap.dat

With some coins, the blockchain will be split into multiple files labeled sequentially blk0000.dat, blk0001.dat, blk0002.dat, .........

In those cases, simply use command line to copy and merge the files and name it bootstrap.dat

That's it.

what is command to merge miltiple files into single file?

Copy /b file1+file2+file3+file4+........ newfile

EXAMPLE:
Copy /b blk0001.dat+blk0002.dat+blk0003.dat bootstrap.dat

This is how you construct a real bootstrap.dat :

https://github.com/bitcoin/bitcoin/tree/master/contrib/linearize

Not sure if that is being offered here, but doing it as a
service would not be unreasonable.

I'll admit, I haven't the slightest clue of what exactly makes your method superior.  I don't doubt you, just saying I've always done it my way without a problem.

It's not my method.

This will not (reliably) create a valid bootstrap.dat.

A valid bootstrap.dat contains no orphans (block files contain orphans) and will have all the blocks in order (blocks in block files may be out of order).

There is a script included with bitcoin core called linearize.py that is used to create bootstrap.dats.

Actually I've never bothered to use linearize.py either, as just copying
block data works reasonable well.

But the point is, if you're offering this as a paid service, it would make sense to
use the right tool, since the simple method is so simple.

I wasn't suggesting you came up with the method and created the script.  I was referring to it as "your method" solely in the context of this thread.

Agreed.  0.01 BTC would be a reasonable fee if he created the bootstrap properly with linearize.py (thanks to gmaxwell for yet again teaching me something I didn't know about crypto), but I assume he was just using the quick and dirty method I outlined.

Thank you for your feedback.

I was unaware that my files would be considered an "unreliable" bootstrap since they are not linearized.

Thanks for the info. I will remove my links until I figure out linearize.py.
