We now are at preliminary review of the new BeerTokens crypto currency spec that uses MultiCoin-exp as the client.  The multicoin-exp config spec is presently published and will be updated from this site: http://exchange.beertokens.info/docs/multicoin/bitcoin.conf.beerA .  The chain is now running at "difficulty" : 50.0 ,  That is designed to be merge mined by other namecoin miners and or bitcoin miners.  It is designed to pay .0001 BEER for each mined block up to block number 50,000 where it will pay .001 BEER.  These future mining subsidies are subject to change depending on market conditions.  This is all we could possibly afford to pay for mining at the start.  If we find we can't get miners to this payoff we might have to wait for licensed mining.  For some details on how to setup MultiCoin-exp for merge mining of BeerTokens see https://bitcointalk.org/index.php?topic=24209.msg394289#msg394289 . If you have any problems setting it up please ask us direct at freenode chat #multicoin so that we know what we need to add to the documentation to make it work for more people.  Note the spec is not finalized yet and it will be evolving over the next few days or weeks.

Update Aug 4, 2011 8:30pm BKK.  I found we have a big bug in the new Diff_post_triger and Diff_triger_block config settings in MultiCoin-exp that cause orphaned blocks after block 12 when starting a new system from an empty datadir.  So this feature will have to eather be fixed or not used.  I'll take a closer look at it tomaro.  This is what happens when you try to do too much tooo fast.

Update Aug 7, 2011 5:43pm BKK.  The above bug has been isolated and fixed with present release of MultiCoin-exp and a slightly modified bitcoin.conf.beerA .  Preliminary test all look good.  I moved out merge mining to now start at block 1500 to add more test time.  A new difficulty change point has been  added at block 1510 but we will have time to change that or delete it if we find we need to.

Update Aug 9, 2011 6:56 BKK.  We have our first merge miner connected to the beerA config spec chain.  Presently the miner is merged with Namecoin and BeerTokens mining at 370Mh/sec.  Soon there will be many more.
