[ANN] Link - The Blockchain File Sharing Protocol
-
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!!!
[code]
C:\NodeLink\NodeLink>node LinkAddressMaker.js
What is the magnet link? aaaaaaaaaaaa
What is the name?aaaaaaaaaaaa
Keywords?aaaaaaaaaaaaaaa

[/code]I’m going to give it a try… wish me luck!

So it ALMOST worked using the client.
Unfortunately the client stuck the change address in the middle of the sequence:

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!

astonished :o

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.

My head exploded like Calem trying to figure out how it works, but as the person on the sidelines,
very happy to watch this unfold.

[/quote]I’m excited too! With all the donations I’ve received I’ve got all I need to make this really work. I expect that by sometime in January, I’ll have something automated that non-techie users can use. With the spec finished (enough to be usable) and the encoding code done, it’s time to do decoding, and then hook it up to the network. If I have the free time, I hope to have it done by this time next week, and then we can start on user interfaces for it! :)
BTW: Is that a pic of you? Or just some random person on the interweb?

[/quote]Ha! Thats totally a pic off of google images under the search happy. I prefer to think of myself as grossly unphotogenic. For some reason that makes me feel fairly content. Like…I take a strange little joy in the idea that my face could break a camera.

[/quote]Its pretty awesome. I’m glad people have had coins to give. I’m too new to have successfully mined coins, but if I ever get to that point, I’'ll be happy to support this too. I’m especially happy for the interface for the people like me, and super happy y’all are using your expertise to do this. :)

[s]Hey Kevlar… Did you get that 110 ftc I tried to send?
My wallets sync’d but it’s still saying 0 of 6 confirms…
I’ve double checked the address and that’s fine.
I can’t see the deposit in the blockchain either.
Any idea what I’ve done wrong or am not seeing?[/s]
Never mind! Confirms going through now.

And… decoding works!
Here’s the output for you non techies with annotations.
[code]
***** First I enter in the test data *****
What is the magnet link? This is a test
What is the name?this is a bigger test
Keywords?This is to make sure we see no data loss
***** This results in a bunch of addresses for FTC *****

***** I then take those addresses, and decode the Link Sequence embedded in them.
Presumably these would come from the blockchain itself. *****

***** I then run them through a parser. You can see each data marker being found in the stream *****
01
10
12
00
***** Finally I output the decoded data *****
This is a test
this is a bigger test
This is to make sure we see no data loss
[/code]This means round-trip publishing, AND reading back works!
Next up is to automate the task of putting it INTO and getting it OUT OF the blockchain. :)
-
Awesome awesome awesome!
-
So. Looks like the best way to publish is to create the raw transaction using the QT client JSON RPC.
I think that makes the most sense for now. That way people can run their own wallet and the Link software, and publish using the coins in their existing wallet. Later I’m sure people will write hosted web services for this where you can send your coins to publish things.
The raw transaction API is here: https://en.bitcoin.it/wiki/Raw_Transactions
I’ll work on it more tomorrow.

I know all I can provide is moral support, but you go rest man… Your doing something quite amazing indeed.
-
Module definition for Link is up. Kevlar, sent you a pull request. I’m going to add FLUX next. Let me know if anything is unclear.
Calem, srsly this is amazing what he’s set up. It has allowed me to get all my ideas organized. I can build on top of Link using the Link format and protocol.

I’m gonna have to take the time to fully comprehend whats going on here, but from what I understand, this is something that A. No other coin is yet to do and B. Takes full advantage of the open-source aspect of cyrpto’s. Sounds like a wikileaks wet dream.
When I have time I’ll try to understand in greater detail. But yeah. I am so 100% behind this project… It’s what is going to make feathercoin more then just a currency.

[/quote]It’s a searchable digital library, a movie theater, a music store, a software thrift shop [glow=red,2,300]and more[/glow] all wrapped up for your convenience into a blockchain that never closes it’s worldwide locations … and it’s all right in your info-box you already use every day.
Probably not the best way to market it though.
