Devcoin

[Shattienator]

Thank you to whoever mined the really difficult blocks 10705 through 10707.  To thank those miners, the miner of block 10705 will get 3/5 share of round 4, the miner of block 10706 will get 2/5 of a share and the miner of block 10707 will get 1/5 of a share.  The difficulty is now increasing and hopefully by around block 11400 the block interval will approach ten minutes.

Also, since no extra big bounties have been awarded, the big bounties can be enlarged, so 4 shares for what used to be a 5 million devcoin bounty.  So Jackjack will get a total of 4 shares for the devcoin block explorer, since he's already received two, he'll get two more in round 4.

Shattienator gets 1/5 of a share for each of his latest two informative posts.  Twobits gets 2/5 of a share for the windows devcoin version.

So the current bounty part of the future account 4 file is:

Hi Shattienator,

Thanks for setting up another devcoin explorer.  The bounty shares for devcoin explorers are now:
4 for the first
3 for the second
2 for the third
1 for the fourth

You'll get 3 shares in round 4.  The current bounty part of the future account 4 file is:

The final purser payouts have been made.

In round 2, Mark will make 4 / 32 * 4,000 blocks * 45,000 purser devcoins = 22,500,000 purser devcoins.  As one of the two general administrators in round 2 Mark gets 5% of the developer share, 0.05 * 4,000 blocks * 45,000 devcoins/block = 9,000,000 devcoins.  Mark sent 300,000 in bounties.

That leaves 22,500,000 - 9,000,000 - 300,000 = 13,200,000 devcoins to share.  In round 2 there are 21 active developers, including Mark.  So Mark sent 13,000,000 devcoins / 21 developers = 628,571 devcoins per developer to all developers except himself:
http://107.20.193.62:2750/block/00000000051f1597603b34bb0b4425d18f9f6b0c3a3026b40ccbfedd4f3dde00

In round 2, Caston made 4 / 32 * 4,000 blocks * 45,000 purser devcoins = 22,500,000 purser devcoins.  One share of round 3 was dropped to enable his purser payment to be done earlier, 1 / 28 * 4,000 blocks * 45,000 devcoins/block = 6,428,571.  That leaves 22,500,000 - 6,428,571 = 16,071,429 devcoins to share.  That gives a send of 16,071,429 devcoins / 21 developers = 765,306 devcoins/developer.

In round 2, Unthinkingbit made 3 / 32 * 4,000 blocks * 45,000 purser devcoins = 16,875,000 purser devcoins.  As one of the two general administrators in round 2, 5% of the developer share is 0.05 * 4,000 blocks * 45,000 devcoins/block = 9,000,000 devcoins.  That leaves 16,875,000 - 9,000,000 = 7,875,000 devcoins to share.  That gives a send of 7,875,000 devcoins / 21 developers = 375,000 devcoins/developer.

Unthinkingbit is handling Caston's key, so Caston's key should end up with 22,500,000 - 20 * 765,306 + 375,000 = 7,568,880 devcoins.  To end up with 7,568,880 devcoins with 22,500,000 starting purser coins, 14,931,120 coins should be sent from Caston's key to Unthinkingbit.  6,000,000 devcoins were sent earlier, so a last send of 8,931,120 devcoins was made.

Unthinkingbit then sent 765,306 + 375,000 = 1,140,306 devcoins to all developers except Caston and Unthinkingbit:
http://107.20.193.62:2750/block/000000000381c718bae8a2f5bd7acf0a6301c9ea61cb1bdef5eaa272dda07fa3

[Unthinkingbit]

At around block 12,000 the first fractional share went out successfully, so there are no longer any known potential technical devcoin problems.  Now we can start projects.

Devcoin was originally intended to primarily be an ethical donation currency and secondly an umbrella for profitable open source projects.  There has not been enough interest in the donation part, so from now on devcoin will primarily be an umbrella for profitable open source projects, and secondly donate a portion to developers.  It will be more like a public benefit corporation:
http://en.wikipedia.org/wiki/Public-benefit_corporation

To that end, the first profitable devcoin open source project will be an open source wiki where the contributors get a share of the advertsing revenue, converted to devcoins, plus devcoin generation shares.  At the beginning the advertising revenue will be tiny, however, that is better than nothing and it will grow.  There are three potential ways of getting advertising revenue:

1) A bitcoin advertising network like Operation Fabulous:
http://www.operationfabulous.com/

2) Handling bitcoin advertising directly.

3) Set up a cooperative in a tax free jurisdiction and connect to regular ad networks.

It doesn't matter what method is used.  All that matters is that only text or picture ads will be accepted, there will be only one ad group on each page, and no malware, porn or scammy stuff.

Whoever sets up the wiki will get a share of the generation to administer it.  However, they do not have total control over the website, they are just administering it for what will eventually be a democratic cooperative.  Of course, they will be part of that cooperative.  There are no notability requirements for the wiki, only the usual no malware, porn or scammy stuff.

The bounties for the wiki follow:

1) Four generation shares to make the wiki.

2) Four generation shares to have some kind of advertising.


The next project is a devcoin / bitcoin exchange.  The problem with exchanges is that bitcoins have been lost and stolen, and people's passwords have been stolen.  An initial list of requirements for a secure exchange follows:

1) Strong passwords are required.

2) If there are repeated attempts to login, login should be slowed or a captcha should be used if it's not already.

3) Passwords should be hashed at least 10,000 times.

4) There should be an off site backup, at least 100 kilometers away from the site.

5) Deposits need at least six confirmations before they can be exchanged.

The first devcoin / bitcoin exchange which meets all those requirements gets eight generation shares.  The next exchange which meets requirements gets six generation shares, the next after four, the next after two.

[Unthinkingbit]

To get some trading soon, there is now an extra bounty for a devcoin exchange.  The person who makes the first devcoin exchange will get a four generation share bounty, even if the exchange does not meet the security requirements in the above post.

If the exchange does meet the security requirements, this four share bounty will be added to the eight share bounty for a secure exchange, bringing the total to twelve.  The next exchange gets three generation shares, the next after two, the next after one.

For all the bounties, if someone wants devcoins upfront instead of waiting for the next generation round, I'll give them four million devcoins in exchange for a generation round share, which lately has been around seven million, but would be less if many people get bounties in the same round.

Edit: This bounty has been doubled:

I'll get right on it. However, regarding passwords, I feel an OpenID system is better than storing usernames/passwords on the exchange itself. This way, people can log in with their (for example) gmail accounts, without storing any credentials on the server.

I agree,  at least the choice of an openid login should be an option.

Thanks for working on the exchange.

As far as passwords are concerned, indeed OpenID sounds better than storing info on the exchange itself.  For the secure exchange:
https://bitcointalk.org/index.php?topic=34586.msg552141#msg552141

I posted that list of requirements by looking over previous times that coins were stolen from exchanges or exchanges lost coins.  As long as the exchange meets the objective of that list, it will get the secure exchange bounty.

Congratulations to the namecoin developers and pool operators for implementing merged mining:
http://dot-bit.org/Merged_Mining
http://dot-bit.org/forum/viewtopic.php?f=5&t=217
https://bitcointalk.org/index.php?topic=44546

Also, congrats to Sacarlson for implementing merged mining in multicoin:
https://bitcointalk.org/index.php?topic=24209
https://github.com/sacarlson/MultiCoin

Because of the recent 51%+ takeovers on alternative coins, we need merged mining as soon as possible.  So there is now a merged mining bounty of twelve generation shares, to be divided by everyone who helps bring merged mining to the devcoin programs, and later add devcoin merged mining to a pool.

[Unthinkingbit]

For the remaining bounties, the developer can choose from either the offered generation shares, or five million devcoins (MDVC) per share or ten bitcoins per share, whichever you prefer will get generation shares.

Edit: Merged mining has been done, there are two exchanges and three wikis, and other exchanges or wikis are not needed; so the options of the devcoins upfront, or bitcoins, have been cancelled. The developer would only get generation shares.


The first bounty is for merged mining.  Because of the recent 51%+ attacks on alternative coins, we need merged mining as soon as possible.  So there is a merged mining bounty of twelve generation shares (or 60 MDVC or 120 BTC), to be divided by everyone who helps bring merged mining to the devcoin programs, and later add devcoin merged mining to a pool:
https://bitcointalk.org/index.php?topic=34586.msg578560#msg578560

The second bounty is for an exchange.  The person who makes the first devcoin exchange will get a four generation share bounty (20 MDVC or 40 BTC), even if the exchange does not meet the security requirements.  If the exchange meets the security requirements, there is an extra eight share bounty (40 MDVC or 80 BTC), total of twelve shares (60 MDVC or 120 BTC):

https://bitcointalk.org/index.php?topic=34586.msg557562#msg557562

The third bounty is for a wiki.  This will be an open source wiki where the contributors get a share of the advertising revenue, converted to devcoins, plus devcoin generation shares.  The developer who makes the wiki will get four generation shares (20 MVDC or 40 BTC).  If the wiki also has some kind of advertising, the developer will get an additional four shares (20 MDVC or 40 BTC), total of eight shares (40 MDVC or 80 BTC):

registering my interest... poolserverj currently only supports one aux chain and will some small mods + a whole lot of testing to enable multiple aux chains. 

BTW how do you get on the devcoin developers list?

Hi Shads,

Thanks for looking at merged mining.  Every alternate coin now needs merged mining to be safe to invest in.

BTW how do you get on the devcoin developers list?

Right now only Mark and I are developing devcoin.  Mark concentrates on building the devcoin releases:
http://en.sourceforge.jp/projects/sfnet_galacticmilieu/releases/

and I concentrate on the receiver list:
https://github.com/Unthinkingbit/charity

If you want to modify devcoin for merged mining, please start by messaging Markm:
https://bitcointalk.org/index.php?action=profile;u=3932

and I with any changes and we'll go from there.

Cheers,
Unthinkingbit

Sorry I meant how does one get onto this list: https://github.com/Unthinkingbit/charity/blob/master/bitcoindonationinformation.html

I'm only putting my hand up for modifying poolserverj to support multiple aux chains which is prerequisite for pools using it to support devcoin merged mining.  I'm not a C/C++ programmer so I can't really help much with the client.

That'll eventually be needed, and would get a part of the merged mining bounty.

so you'll be getting devcoins starting in round 5.

Also you'll get a share of the bitcoin donations from the Mainframe Mining Cooperative:

if they reopen after the DDOS attacks.

[shads]

thanks unthinking bit... I better go download the client and take a proper look...

[shads]

btw the most recent commit of poolserverj should remove the restriction of a single aux chain.  Can't test it properly though until there's another merged mining capable chain.
