\[Kickstart\] Link - The File Sharing Blockchain Protocol
-
Tonight I finished the decoder and encoder. All the op codes EXCEPT for the two Date ones. That’ll be tomorrow. It also now does payload verification if verification meta-data is present.
I’m still targeting raw transactions this weekend.
I was thinking this is going to need a logo… and I happen to know just the artist for the job, if he would like to volunteer his services? Please? You do such good things with the Feathercoin logos… I was thinking something with a chain coming out of a brick or cinder block (you know, a blockchain link?), but I’m sure whatever you come up with will be awesome.

Another night, another progress report on your investment.
Encoding and decoding of payload and ALL meta-data is DONE! Multi-transaction links are not even on the radar yet, and may get dropped for the initial release since you shouldn’t need them ever unless you’re doing something massive, in which case you should probably just make a torrent and encode the magnet link instead (duh!). But I’ll leave them in the spec because such things may still be useful for other functionality.
The library has been published to npm as ‘blockchain-link’, so it can be used by anyone with node. Just ‘npm install blockchain-link’, and you’re ready to start encoding and decoding:
[code]
LinkSequenceBuilder = require(“blockchain-link”).LinkSequenceBuilder
LinkSequenceDecoder = require(“blockchain-link”).LinkSequenceDecoder
[/code]Nice and tidy! Good clean code. There’s also a test harness that’s been broken out into a separate file and demonstrates how the encoder and decoder work.
So, that leaves me with little excuses left to start doing raw transaction building and parsing, so once you’ve encoded your data, you can get it on to the network and into the blockchain (kinda the whole point, right?). Anyone got a quick and easy way of doing it, or am I on my own for this one?
-
This is awesome! Do you think that some sort of GUI is required for this?

[/quote]I speak of none other than the profound artist that is… iawgoM! May his grace be upon us.
I’m sure a percentage of the donations would find their way into your wallet, if that would help to give you incentive.

[/code]That right there is a zero fee spend with the the outputs ordered correctly, posted to the network without doing anything more than pushing a button.
Now the terribly interesting question becomes: Will it confirm? If so, how long will it take?

If you see a transaction there, it confirmed!

[/quote]That’s right lizhi. There’s a lot of value in saying, “My data is being verified by networks faster than all the top 500 super computers in the world combined.” If a coin is doing this, it must be valuable because that’s a valuable service.

Go home, Stevenrm87. You are drunk. ::)
So… guess what’s not confirming.
Yep. The 0 fee transaction. Totally expected. It’s got a ton of dust outputs, and no fee. So, tonight I’ll try it with 0.1 fee, just to be sure it’s working, then we can try stepping down the fee and seeing what will confirm and what won’t.
I’ve been thinking about reading. It’s a MUCH harder problem. Publishing was easy. Reading requires parsing the blockchain itself, and creating a database of all the metadata in there so it can be indexed and searched by the user. This makes me think that in the future, people will bootstrap the Link index for a coin, the same way they bootstrap the blockchain download: By providing a torrent of the data up to a certain point.
Anyone know a good way to read the blockchain off the disk in LevelDB format?

I just parsed Link data out of the Blockchain itself. Swear to Bob.

[/code]That look familiar Tuck?
It’s using the QT client as it’s source for the Blockchain. You have to do a little configuring and reindexing of your QT client, but it’s a one time operation and didn’t take more than 20 minutes to reindex everything on disk.
And with that, Phase 1 is COMPLETE.
It’s official: Link is alive. Code is WORKING!
Here’s what we have so far:
Link protocol encoding for all data and meta-data types
Automatic posting of Link transactions to your blockchain of choice via your QT wallet (you’ll need funds in your wallet)
Link protocol decoding for all data and meta-data types
Automatic scanning of your blockchain of choice via your QT wallet for Link protocol data.
Unit tests to demonstrate round trip publishing, and subsequent reading.And so begins Phase 2.
The goal of Phase 2 is to provide a user interface for the above functionality, specifically publishing and searching.
The publish mechanism should allow you to enter in any or all of the data and meta-data fields, and spend the transaction on your behalf. For now we’re going to stick to magnet links, but later versions can do whole files.
The searching should contain a persistent disk based index of previously scanned Link data, so that upon startup it will only need to scan what it hasn’t seen before. Fortunately this seems to be pretty quick with small blockchains like Feathercoins. I can’t immagine Bitcoin is going to be as fast, but you can take shortcuts like say, “Well, there’s no data before block X, so we’ll just skip everything before X.” which can make it feasible. It should allow the user to search any of the meta-data, and execute any payloads chosen by the user.
This interface will be a web based interface, but you will run it locally so it can talk to your client. It will require a little bit of manual installation steps, but nothing that can’t be distilled into a README and performed by well trained monkeys like Tuck here (I bro-love you man).
After that, Phase 3 can begin, but I won’t reveal what’s in store for that just yet.
I’ll keep you posted. :)

Kevlar,This was on my mind for a few days, so I went ahead and did it anyway:

[/quote]I REALLY like the imagery!!! +1 rep good sir.
What does everyone else think? Let’s here some other opinions!
[/quote]I think this has all atributes of good logo. Clean, simple, with good idea…

I just parsed Link data out of the Blockchain itself. Swear to Bob.[code]magnet:?xt=urn:btih:fbab636f9c91fb58038055dfce83cd8099a7366e&dn=TPB+AFK%3A+The+Pirate+Bay+Away+from+Keyboard+%282013%29+720p+h264+581m

[/quote]The more I look at it, the more I love it. Can I get the psd/ai? And any chance iawgoM might work his magic using it in conjunction with the block-chain? Because I can’t get enough of that either, so I’m hoping this will be a whoops your peanut butter just got all over my chocolate moment.
