Bitcoin Blockchain on Blu-Ray

[RealBitcoin]

But who is going to verify and authorize the production of your Blockchain storage devices?

Everyone verify it for themselves.

 Why would people trust in you? You can't just expect to whip up some discs and slap a Blockchain badge on them and people will come buying these like hot cakes because they can't just download it themselves? And people with limited bandwidth won't even care about running a node in the first place nor owning legacy Blockchain data on their bookshelves and they will use a simple online Bitcoin wallet to do business instead.

Hey no need to be hostile it's just an idea. And the free market will decide if there is demand for this, not you.

So I just gave an idea for entrepreneurs, and we will see if anyone will do this.

I was thinking about, does anybody want to startup a business that will sell the bitcoin blockchain on Blu-Ray disks, so that people can have their blockchain secured and archived? I just gave you a good business idea.

Why exactly bluray? Why in a dying technology insert a new tech?

I`m not sure what you mean by dying. I still buy disks even though I own some USB sticks and external HDD drives.

USB type drives can easily be corrupted, which I dont like. Sometimes the simplest item is the safest, hi-tech is not always good, especially if you want to validate the authenticity of the bitcoin blockchain.

So disk storage is perfect for that IMO.

I am not being hostile to you, you asked the people of the forum a public question about our opinions so I stated mine. Mind if I ask would you run a free software someone handed to you on the street on your computer fully trusting them that it's not malware or something insidious isn't lurking in there? Have you seen the tv show Mr. Robot? For this to work every cd will need to be verified to be safe before releasing on the market. And yeah the free market will decide if they want to buy something they can get for free on the Internet for a couple of days' worth of downloading stuff.

Honestly, I think this kind of business would work but not so much as you can consider it a 'successful' one because I'll be frank that there are only a few percentage of users who would want to buy blockchain in a blue-ray discs.

Has anyone proceeded with this idea? I was thinking about the same. Not as a business, rather as archiving the chain for a long time. I picked blu-ray, because it's long lasting and EMP resistant medium.

If you want to keep such records yourself, go ahead. Honestly, I don't see the point. Hundreds of new blocks are added to the chain each day. If you saved the latest blockchain data on Blu-Ray today, in just one week from now you would be like 5-7k blocks behind. It gets bigger the more time passes. Data on CD's and DVD's tend to get lost with time, at least in my experience.

There is also another factor worth considering. It's not 2016 anymore. Many modern laptops don't even come with CD/DVD drives anymore. And in the future, there will be even less demand for it. Everything is online now and fast internet connection allows us to access that data from online sources.

I didn't want to answer to a topic so old (you should have been asking in a new thread), but since @Pmalek has done that, I'll continue.
Keep in mind that new blocks are added continuously to the blockchain. So most probably at the moment you've finished burning the BR, the data will already be (a bit) old.

Plus, it's not advised to get the blockchain from somebody else, so the original business could not work. If you do this for yourself - it's up to you.


I don't agree 100% with @Pmalek (I agree with him only 98%), a backup like this has the potential to save you some time when your HDD will crash, but that's the only use I see. That's not much though, plus with every day passing more and more data is added to the blockchain and if you go on this road you may have to make regular such backups (maybe every year).

I'm not going to continue this threat then. This is the last post. CD and DVD lasts much less than BluRay discs. Point is to shield from EMP attacks. I'm aware that I won't have latest data, but loosing 1 month seems still much better than loosing full chain. Main point is to have some kind of disaster recovery. Armageddon recovery.

A personal achieve makes sense. It's especially useful if you have a slow internet connection, and it would take you days to download and synchronize the latest blockchain data. I wouldn't overdo it though. Once every 3 or 6 months maximum. Those archives of yours would quickly grow in a physical sense if you burned new Blu-ray discs every month.

Blu-ray's are only a few dozen GB large max, so there's no way a single disk will hold 450GB of a blockchain. Handling multiple disks in the correct order quickly becomes a PITA, the read speeds for all that data is not going to be great (better than with a slow network connection, but still), and also most people don't have a blu-Ray drive (or even a DVD drive) because they are expensive and out-of-favor.

If I was pursuing this idea, I would use old 1TB HDDs instead of discs.

Well, one more reply, since you hit the nail. That's precisely why I was asking if anybody did try to go forward with this idea. I'm thinking about how to distribute files into BluRay with as little pain as possible. My plan:

1 disc will be MAIN and it will include:
/.bitcoin/chainstate/ directory. It's possible to add new files into disc, so I don't have to use new disc every time.
+ bitcoin.conf (not really needed)

2, 3, 4, 5, 6 ++ discs will include only files from /.bitcoin/blocks/ directory. Which seems to be nice to handle. Only blk*.dat and rev*.dat files. One or two pairs of such files are created every day and never modified later (ignoring deep rollbacks). I have 100G size discs, so it's not too many discs even for some years ahead.

files in main /.bitcoin/ directory: peers.dat, mempool.dat, banlist.dat, fee_estimates.dat, debug.log, onion private keys, wallets --> will be excluded (I think this should be fine)

then I have /.bitcoin/indexes/txindex/ .. which is probably not needed and can be rebuild? I don't know.

That should be all. If you can ACK/NACK my plan, let me know. I do have Blu-Ray drive, so that part is okay with me :-)

You just need to clone the blocks/ and chainstate/ folders, but other than that it's an ACK. You don't need bitcoin.conf config file.
