Ok, Payload op-codes are in, Meta-data op codes are up next. Also ZD’s organizational changes to op-codes has been implemented. 0 is Payload, 1 is Meta-data, and F is sequencing.

Anyone else have any other op-codes they would like to see?

Suhweet. :)

be gentle, I have no clue what’s possible or already handled by something else but …

If there will exist categories, will they be handled via the keywords?
(source file) File type.
(source file) File size.
A few “Arbitrary user-defined meta-data” to be used as users please. Possibly to cover the three above.

Edit : What about the ability to make these private? Sure the source file can be encrypted, but what about allowing entries to be private (password protected or otherwise) or the ability to designate who the source files are made available to be it individuals or a group or a continent, etc.

I’ll take #2 for Flux. I’ll play with some kind of module registration steps but we are go. o/.

I’m not completely against that, but file type is discoverable from format in the beginning of the file. File size sounds like an important one tho.
Keep in mind, we can use modules now and modules can replace each other except 0 and F. 1 is a feature of Link so required for full Link, but it’s not as critical as the core and sequencing.

Think of it like mix and match modules in the same blockchain for custom applications without the 80+ odd coin.

zerodrama

Kevlar, I think you did it better. With the exception of 0 and F, the 2nd byte F is the only one that needs to be explicitly describing the module itself.
So now there’s 15 OpCodes for each module.

0 is the core, F keeps it tied together, 1 is for users. I claim 2 (20 - 2F) for FLUX.

EGGCELENTE.

There’s no one else doing this lol. I love it. They’ll be cloning us soon.

Kevlar, I forked the suppository. I’ll be working on Modules.md and modules/FLUX/README.md. Goosebumps.

Categories are something that can be left up to the users to define. For instance, they could make a special keyword that starts with a #, and whatever follows it is a category… “#tucksporn”. Then it’s up to the client how they want to deal with organizing them.

Well, it’s the blockchain. You can’t specify who can/can’t see the blockchain. Encryption is the correct solution.

Perfect. :) 2 is reserved for Flux!

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?

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.

Yes it would.

Link protocol simply makes torrent files available.

Flux will enable massive file storage.

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.

Kevlar

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!

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!

[/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?

+1 rep
and
110 ftc coming your way.

[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]

Kevlar

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!!!
