FYI: I've collected more article series and samples about building
your own blockchain(s) at the Awesome Blockchains page .
Anything missing? Let us know. Happy blockchaining.

Hey guys, I'm actually the one who wrote this. Really glad to see
it here and that people think it's worthwhile.I mention this in the
post, but the reason I started this is to learn more about how
blockchains operate. I've never been that into them, I don't invest
in the coins that the big ones operate with, but am more interested
in how they work and other use cases. As with everything, the best
way to learn is to write one yourself. I definitely don't consider
myself an expert, but when I go back and read the Satoshi paper and
Ethereum's white paper, it makes way more sense than before.Let me
know if you have questions, or if you don't agree with something I
wrote. Want to make sure people reading this can get more info out
of it than many of the other articles on this topic.

Thanks for the blog series, Jack! When is your ICO?

Hah yeah that's not gonna happen. If it were, you'd get to give
it a name though. Maybe something to do with Master and
Margarita, one of the better books people have said I should

Can't wait for part 4, I've been following this series very closely
and really appreciate the details the author has included. Way more
in-depth than the typical "build your own blockchain" submission.

Thanks, really like hearing people like what I wrote. And
definitely trying to write more in depth than some of the other
posts on this topic. Hopefully more to come.

Random idea: a logging/audit framework with built in blockchain
support to prove events happened/didn't happen. Maybe an extension

You can sign log messages several ways without blockchain. Even
systemd (cough) has support for one crude form, which it calls
forward secure sealing. Not sure what proof-of-work, which seems
to be the subtext and is really intended for distributed lack of
trust, would buy you in this situation.I can think of a
reasonable blockchain-like implementation for logs, actually:
chunk up the log, sign, include the hash of the prior sig as the
first log message in the new chunk. Boom, blockchain! Throw in
Merkle trees somehow and you?ve got yourself a VC-funded startup.

This would be useful to ensure you aren't missing any log
data...an issue near and dear to my heart these days.

Indeed. That might actually be a good idea for government
records and other legal documents.
