@oleganza, I recommend cross-posting to the bitcoin development mailing list for more commentary.

Anyone claiming to be Satoshi Nakamoto can prove it simply by signing something with his/her private key. Anything less than that is inadequate.

Of Course.  It would be amazing to see a "I certify that I (Name) am the original creator of Bitcoin" by the origin's block key.

In light of the scale of this project I've updated my bounty to 2btc
68  Economy / Services / [Programing C++] Port of zlib to pure ISO C++03! Bounty! 2.2 BTC on: December 13, 2013, 01:57:27 AM
Bounty! (for Open Transaction Project)

Port zlibc to zlibc++ and earn Bitcoin!


Rules.

1. Github project with good documentation.
2. Autotools compile on many platforms.
3. 'make check' with comprehensive unit tests and functional tests.

License:  (same as zlib): http://en.wikipedia.org/wiki/Zlib_License

ISO C++03 strict compliance code, no warnings compile with GCC and clang.

Good luck!


Randy and Fellow Traveler (and of course myself) are going to be on the review board for this project.

Pledges:

da2ce7: 2.0BTC
randy: 0.2BTC

any questions/comments please comment on this thread.

Thank-you for your reply's.

I've made an updated release of Open Transactions for windows. (0.89.q)

The test-data is available for download here:

https://github.com/FellowTraveler/Open-Transactions/archive/master.zip


You need to copy it into the %APPDATA%/OpenTransactions dir.

You will also need to run the otserver.exe Smiley

@moltenmich

The blue-globe one is winning so-far:




If there is no new entry, we may close the competition early.  PM me if you are still working on something.
75  Economy / Services / Re: Open Transactions Logo Competition! 2BTC on: June 06, 2013, 05:50:26 AM
@moltenmich, great work so far

Not to pre-judge, however I love this one:
76  Economy / Services / Re: Open Transactions Logo Competition! 2BTC on: June 06, 2013, 12:29:09 AM
that was just a rough draft. i don't have any vector creation software but i can do a professional logo in a very large size. will work on it sometime tonight

Unfortunately, even large raster images will not be accepted for the bounty.  We need clean SVG files, (or Illustrator).
77  Economy / Services / Open Transactions Logo Competition! 2BTC on: June 05, 2013, 03:12:15 AM
Over in Open Transactions land, we are finding ourselves in need of a Logo.

So in true Bitcoin fashion, we are having a competition!

Rules:

Must have two versions: Greyscale and Colour (must look good in both).
Must be in a Vector Graphics format.

(optional) a banner version.


This competition will be open for at-least 2 weeks, or until we have found a great logo.

The prize pool is 2btc atm.  People are welcome to donate more to: 1D9eWaBqawJH4KUb5frWpwZtzkuSZEMnG3

Happy drawing.

Judges: markm, FellowTraveler, da2ce7

78  Bitcoin / Development & Technical Discussion / Re: Please do not change MAX_BLOCK_SIZE on: June 04, 2013, 05:28:58 AM
My point is that the same argument applies to Open-Transactions, or any other known distributed money system.

While Bitcoin was small, a low-importance transactions were fine, as the entire network size was small.  However as the network increases in size, so must the 'importance' of the transactions.  Otherwise it becomes disappointingly costly to maintain the network -> thus, creating great economic incentives to centralize the network.

If, for example, fees are LINEARLY related to Network-Size, then the cost of maintaining the network will be LINEAR * LOG (number of unspent outputs).  Or just LINERAR, if you have an unlimited amount of random access storage (eg. RAM).  This is a sustainable proposition. (The fees will pay for the cost of running a node).

The position argued, by some, is that the cost to make a transaction on the Bitcoin network should be CONSTANT.  This means that the cost to run a node on the network (while maintaining the same quality of decentralization); will be increasing faster than the amount of fees, per node.  -> Thus creating an economic situation, where either:  Nodes are subsidized, or the ratio or full nodes vs. uses goes down.

I, personalty, value a very decentralized and non subsidized processing network of Bitcoin full-nodes, more than the utility advantage of having low importance transactions.
79  Bitcoin / Development & Technical Discussion / Re: Please do not change MAX_BLOCK_SIZE on: June 04, 2013, 04:28:55 AM
The cost of checking any one transaction is:
O (number of full nodes) * (cost of checking a transaction).

There is no protocol reason why more than 1 full node needs to be running. If there are N full nodes, it is because N-1 people decided it was a worthwhile investment of their time and resources to do so. Open-Transactions runs with a single validating node, the server. But audit information is (in theory) available so anyone can check that the server isn't lying. And if they were to do so for all transactions processed by the server, then it would incur the same overhead. Now typically in Open-Transactions one only verifies their own receipts, but the same could be said for SPV/SPV+ clients.

This conceptual argument I take issue with:

... There is no protocol reason why more than 1 full node needs to be running...

The very security model of Bitcoin requires there be multitude of full nodes, unless, if there was only one full-node, then non-bitcoin transactions could be possibly slipped in (unaware to SPV nodes).

For the current standard of decentralization to hold, we need a constant ratio of full nodes vs users.  Having only a few full nodes is a very much a higher-trust security model than what the Bitcoin Network currently provides.

People who advocate a high tpc, must necessarily, advocate a more centralized full-node processing network.  (Because of the QUADRATIC cost of maintaining the decentralization).
