I’ll take #2 for Flux. I’ll play with some kind of module registration steps but we are go. o/.
[/quote]Perfect. :) 2 is reserved for Flux!

Kevlar, I forked the suppository. I’ll be working on Modules.md and modules/FLUX/README.md. Goosebumps.
[/quote]Awesome! Very excited. ;D

Ok! Meta-data is done, sequencing is done, and the first example test sequence is done! How exciting! Go check it out!
I’m going to do one more example sequence, then I’m going to encode it and send it to the blockchain! I’ll keep you posted!
I need a torrent to encode for the next example. Specifically a magnet link. Does anyone have any suggestions?

I think I’ll take on the job of cheerleader.
You guys are doing awesome!

Just reading about this guy:

Looks like a similar - albeit different concept.

That looks like it would be one giant chain. Please forgive this question, because it’s been birthed in a pool of total ignorance, but would a file sharing blockchain suffer issues from a ballooning size? I know there has been mostly technical discussion here, so if its been addressed or is irrelevant, just pat me on the back and give me a sugar cookie.

[/quote]Yes it would.
Link protocol simply makes torrent files available.
Flux will enable massive file storage.

[/quote]No… blockchains with lots of usage suffer from a ballooning size. When you embed Link in the blockchain, you destroy coins, meaning you’ll NEVER send them again. That means you’ll NEVER grow the blockchain with those coins again.

Ha! I did it.
Wrote up a program in Node that accepts the magnet link, name, and keywords, and generates the addresses. The code is in github here: https://github.com/TSavo/Link
You can even check them on blockchain.info, and see the link encoded message!
[code]
C:\NodeLink\NodeLink>node LinkAddressMaker.js

[/code]Try putting that first address into blockchain.info. Not only is it a valid address, but if you look at the hash160, you’ll see the Link protocol in action!

^^^^^^^^ Link Start sequence
^^ Inline payload op-code
^^^^ size
^^^^^^^^^^^^^^^^^^^^^ The magnet link (well, the first few bytes)
[/code]Ooooooooomg so exciting!
Ok, next up is to do it with Feathercoin addresses, and then to actually send the transaction using your donated coins.
But for that I need to know: What’s the Feathercoin version number? Bitcoin is 0x00 for mainnet. What’s FTC’s?

[size=8pt]Sorry, tried to cut or hide or spoiler but I couldn’t figure out how. If someone can give me the BBcode, I’ll fix this… or simply just remove the screencap.[/size]

Ok, I spent a bunch of time cleaning up the code.
You can now do:
[code]
var sequence = new LinkSequenceBuilder();
sequence.addPayloadInline(magnet);
sequence.addName(name);
sequence.addKeywords(keywords);
var buf = new Buffer(sequence.toString(), “hex”);
var addresses = encodeAddresses(buf, 0x00);
for (x in addresses) {
console.log(addresses[x]);
}
[/code]Which I think is a whole lot cleaner than my first pass. Bushstar just got back to me with the version number for Feathercoin so I’m gonna give it a try here in just a few…
Edit: Tried it out in the code… looks pretty feathery to me!!!

C:\NodeLink\NodeLink>node LinkAddressMaker.js

So it ALMOST worked using the client.
Unfortunately the client stuck the change address in the middle of the sequence:
[url=http://ftc.cryptocoinexplorer.com/tx/cc66ef78c1bcfbaf2a691b3dda77847bc80350ad262f17af38f7950879ecaef2#o2]http://ftc.cryptocoinexplorer.com/tx/cc66ef78c1bcfbaf2a691b3dda77847bc80350ad262f17af38f7950879ecaef2#o2[/url]
Bummer. Owell, this simply means I’ll have to write my own client to do the sending so it always gets the sequence in the right order.
OMG I’m so excited that this almost worked. If you ignore that change send, you can see it totally did exactly what it was supposed to!!!
Tomorrow I’ll work on some code to reverse the process and read them back out of the blockchain. It’s pretty straightforward actually. ;D

Hi five!
I’ll be watching with anticipation. This seems to be the most awesome idea I’ve seen pitched for the use of the network to date.
100% Behind you Kevlar!

Can we use Pay to Script Hash for Link?

This is really sweet. I’m going to take a look at the spec tonight after work.

[/quote]Yes, we could, but I’m not sure what would be gained. It’s 20 bytes in the address, or it’s 20 bytes in the script. Since this doesn’t need to interoperate with the blockchain protocol, I feel pretty strongly that making it as simple and standard as possible is the way to go, unless there’s a really compelling reason to use p2sh. Can you think of one?

[/quote]My brain instinctively goes meta like doge on crack. P2SH would keep that window open. We could use scripts to save some common searches, such as for translations of content that is in torrents. The torrent would be in one place and people could use different addresses to find parts they want.
Just a habit of mine of taking any constant assumption and making it a variable.
