[ANN] cbitcoin 2.0 - A Bitcoin Library in C

[MatthewLM]

Yes, there is a lot of pressure on me, but that cannot be fixed by leaving the project. The pressure is on to make this a success for me and everyone else. I cannot do that by quitting. That is simply unthinkable. The pressure is not to quit under any circumstances and to keep going.

And "future of bitcoin" is in reality subjective. Different people will have different ideas for the direction of bitcoin. Obviously I think I am going in the right direction but others may disagree. But I can say with almost absolute certainty I will continue on this project and release cbitcoin 2.0. It will happen a lot faster with donations though.

The easy solution was simply to remove the unnecessary boldness from the title.

"Not-drawing-attention-and-simply-doing-good-job" way was always easier for me, but if you like to do it the harder way, then by all means - proceed as you like.

Keeping a low-profile does not help me receive contributions from other people. Contributions not only including donations and code but suggestions, criticisms etc.

MatthewLM,

I think you should create account on Gittip to receive donations, see: https://www.gittip.com/about/
They probably have plans to support Bitcoin, see: https://github.com/whit537/www.gittip.com/issues/14

Thanks for the suggestion, though whatever service I use, it should be suited for the fact I have a UK bank account. I'll take a further look at fiat methods of donations tomorrow.

I'm also looking for a suitable noSQL database for block-chain storage, so I'll hopefully sort that out tomorrow: http://stackoverflow.com/questions/13317443/an-alternative-to-leveldb-that-allows-you-to-read-a-subsection-of-the-data-recor But for now, I'm off to bed

Not sure if you know this but the creator of Armory, etothepi, was able to raise over $4000 for this bitcoin client using rockethub.com.

[MatthewLM]

Well all together I've found these websites which provide the type of thing I'd want:

http://www.rockethub.com/ (Thanks jimbobway)
http://www.kickstarter.com/
http://www.crowdfunder.co.uk/
http://www.indiegogo.com/
http://www.chipin.com/
http://www.gofundme.com/

I'll have to carefully go through them all to determine what I want. If anyone has any comments about them, please post them.

is this a bitcoin fork?
whats different about this fork?

sry OP is one huge wall of text, no time...

[MatthewLM]

No it is not a fork, it is a complete re-implementation of bitcoin, in the C programming language, as a software library.

[adamstgBit]

No it is not a fork, it is a complete re-implementation of bitcoin, in the C programming language, as a software library.

would cbitcoin start its own blockchain?

or is it just a re-implementation of bitcoind, for cleaner code, and would use the same blockchain as bitcoin?

[MatthewLM]

It uses the same block-chain as bitcoin. At the moment it has code for the production netwok but I plan to add testnet support also and maybe more configurable features for new chains in the future as well.

The code should be cleaner, yes, and have more documentation. On top of that, the fact my code is a library will make it more useful than bitcoind, it will have fewer and more configurable dependencies and will hopefully be more efficient, but that is yet to be judged.

+21 million 

I will donate a small amount sometime soon

Thank you!

And thank you too. 

[MatthewLM]

Well I'm undecided between http://www.rockethub.com/ and http://www.indiegogo.com/.

The fee structure is reasonably similar:

http://rockethub.com

Reached goal = 4%
Failed goal = 8%
Transaction fee = 4%

http://indiegogo.com

Reached goal = 4%
Failed goal = 9%
Transaction fee = 3%
Plus $25 bank transfer fee.

I personally like the interface of indiegogo more. What do others think?

[hazek]

Just opening up both homepages I'd say I like the Indiegogo interface better but I like Rockethub more because of the activity ticker. But this is purely superficially speaking and I think I'd try to figure out which one is more popular and go with that one.

[MatthewLM]

I'm going to decide tomorrow. In the meantime I'm going to leave a poll up so people can give their opinion.

#MatthewLM:

Hey Matthew, does your client allow user to risk re-sending "fresh" coins without a fee, or do I have to fork cbitcoin the same as i forked mainline client ?

EDIT:
By "fresh" coins i mean just received coins but having 6-7 confirmations. Official client won't allow to re send these, so this is the reason i created my fork.

[MatthewLM]

cbitcoin is not a client, nor will it be. When it is finished you could use it to create your own client which follows any behaviour you'd like as long as it works with the protocol. The full node implementation will provide the block-chain validation and you will be able to register events for incoming transactions which match addresses as well as for when transactions are found in blocks I've not got to implementing any of that yet.

It's really hard selecting which funding platform to use. There are advantages and disadvantages to both platforms it seems. I don't like indiegogo's checkout system which annoys you about paypal... I think I'll use rockethub. Any ideas for rewards? There's not much I can do. I could create a "Contributors" webpage on cbitcoin.com with a "Financial Contributors" or "Sponsors" section where I can place people's and business names with website links, logos and/or bitcoin addresses.

Perhaps there could be gold/silver/bronze sponsorship?

EDIT:

So the satsohi client doesn't allow you to make transactions from outputs just found, even when they have 6 confirmations???

I'll get the fundraiser page up probably tomorrow...

I've been working on a B-Tree implementation for indexing. If anyone would like to help, the deletion algorithm need finishing and testing: https://github.com/MatthewLM/cbitcoin/blob/master/src/CBAssociativeArray.c#L154

And I'm following this but I can figure it out in my head: http://www.scribd.com/doc/18210/B-TREE-TUTORIAL-PPT

I'm not sure what he is talking about unless maybe it's newly generated coins, which need 120 confirmations.  With regular transactions, I can respend received coins after 1 confirmation.
