Different format for blk*.dat

[jackjack]

As you surely know, Luke-Jr thinks it's intelligent to put prayers in the block chain...
Because of him we now have that with a simple "strings -n 20 blk0001.dat":

It seems that I'm nearly the only one that such things disturb, so, ok for the prayers
The problem is that:

Code:

LUKE-JR IS A PEDOPHILE! Oh, and god isn't real, sucka. Stop polluting the blockchain with your nonsense.

Which is not only something we will never know if it's true, but also the beginning of a blockchain religious war and part of a tx so not deletable

I don't know what is worse, a religious war or using a format not as simple as raw data...

solution:
start deleting spend transactions. and keep only the headers

you could of course still put strings in the block chain, by not spending. but...

[jackjack]

These transactions are never spent because nobody can spend them
They send coins to a given pubkey, of which nobody has the privkey

Nice idea though if we want to reduce the size of the blk files

[EricJ2190]

I see no reason to change the storage format over this. It might obfuscate transaction messages in the blockchain, but they will still be there. If people care enough to read the messages, they will use an old client or parse the new format.

[wareen]

If people care enough to read the messages, they will use an old client or parse the new format.

Sure, but if you only need a few keystrokes to make possibly offending/illegal content readable on any (*nix) Bitcoin system without having to download any special program this might become a problem for Bitcoin and justify obfuscating blk*.dat.

As soon as you need additional tools to unlock the content, these tools themselves become problematic and can be blocked/outlawed much more easily and with less harm to Bitcoin itself.

Why take the chance?

Sure, but even text can be both.

Of course, this is just one aspect of the "problematic content in the blockchain" debate and maybe we can afford to wait with a solution until it really becomes a problem but on the other hand it doesn't feel good to see that the blockchain is already abused for expressing strongly religious views

[helloworld]

Why does the blockchain format accommodate arbitrary text anyway? Who's idea was that? Mr Nakamoto.

If there's currently space for random text, couldn't the blockchain just be smaller instead?

Meh, I have that on a shirt, and probably dozens or hundreds of copies scattered around my hard drive.  What's one more in the blockchain?

It would be very difficult to prevent arbitrary text since it needs to store arbitrary data. A standard address is just a sequence of 20 bytes. What is stopping anyone from making those bytes an ASCII string?

As soon as you need additional tools to unlock the content, these tools themselves become problematic and can be blocked/outlawed much more easily and with less harm to Bitcoin itself.

How would we restrict the tools? As long as Bitcoin is open-source, the blockchain storage format is openly available. As far as I see it, it would be wrong to try to block or outlaw tools for parsing the blockchain. People should be able to freely analyze its contents.

If we have a problem with content in the blockchain, we need to either find a way to deal with it or learn to accept it. Hiding it won't make it go away.

[kokjo]

if you don't like luke-jr putting stuff in the blockchain:
sent coins to 17yH22jVieEWq2voErEtwuajx5bq9djfpa

it *should* show up as "Luke-Jr Sucks       " in the blockchain

Yes I agree and I'm not in favor of restricting any tools, but by requiring tools not readily pre-installed on millions of computers you raise the bar for anyone wanting to trash the public's opinion of Bitcoin.

If you distribute encrypted copies of illegal content, the recipients are far less likely to get into troubles if they don't possess the key. The "key" in this context would be the tool that analyzes the blockchain.

/usr/bin/strings from binutils hardly qualifies as a "key" because everybody already has it.

If we have a problem with content in the blockchain, we need to either find a way to deal with it or learn to accept it. Hiding it won't make it go away.

True - I'm just arguing that changing the blockchain format is easy compared to Gavin et al. or bitcoin.org having to fend off the next DMCA takedown notice. By making the blockchain less attractive to distribute arbitrary data we can probably reduce that risk.

Sorry, can you help me learn why "it needs to store arbitrary data"?

Why was the space made available when the format was created?

Was it to store 20-byte addresses?

Are they 'to' or 'from' addresses, or something else?

Where exactly can I read the technical details of why things were designed this way?

Thanks!

see the transaction structures.
and also the scripting.

[kjj]

The short version is that a transaction output is created by signing part of the transaction with the hash of a public key (from the address).  The transaction signature is random, meaning that it can be anything.  Usually, it just looks like garbage, but it could, by random chance, turn out to be an ASCII text string.  So, the block must store arbitrary bit strings, because literally any sequence of bits is potentially valid.

So, if you want to embed text into the block chain, all you need to do is keep creating keys and transactions until you find one that just by chance has a signature that just happens to be the ASCII text you want.

Or, you can do it in the other order: just put your text in as the signature, and then go looking for the key so that you can redeem it later.
