Steem - A experimental Proof of Work blockchainSource Code:
https://github.com/steemit/steemMining Begins on Thu, 24 Mar 2016 17:00:00 GMT, no blocks will receive a reward until 21 POW are submitted.

How to Mine cd programs/steemd
./steemd --miner='["accountname","${WIFPRIVATEKEY}"]' --witness='"accountname"' --seed-node="52.38.66.234:2001" --mining-threads=2
Account names must be all lower case, less than 15 characters, and start with letter
WIFPRIVATEKEY is a Bitcoin style key export 5....
Extra Seed Nodes:52.37.169.52:2001
52.26.78.244:2001
Or edit datadir/config.ini which has a template for most args.
Command Line Walletstart steemd with --rpc-endpoint

Let H = Head Block ID
Let H2 = SHA256(H+NONCE)
Let PRI = Producer Private Key
Let PUB = Producer Public Key
Let S = SIGN(PRI, SHA256( H ) )
Let K = RECOVER_PUBLIC_KEY( H2, S )
Let POW = SHA256( K )
The consensus algorithm works as follows:
At the start of the chain, "initminer" is the only node that can produce blocks, but it does not get paid. In fact, no one gets paid until 21 miners solve a POW.
Every time miner solves a POW and broadcasts their transaction, it gets included in a block and they get added to the queue.
The top 21 miners in the queue are selected as a "round" and are randomly shuffled. Then they produce 21 blocks.
At the start of each round one miner is popped from the queue (reducing queue length), and bringing in a new miner.
Once your miner is in the POW queue, you cannot submit new POW until you exit the queue. It takes about 2 hours to move through the queue. In effect, if you have more than 0.2% of the total hash power you should have multiple accounts mining.
Moderation
This is how I intend to moderate this thread:
1. any posts that fundamentally disagree with the initial mining / launch strategy are not productive and will be removed
2. any posts that are not civil and respectful will be removed
3. any posts making false accusations will be removed
Note: The original launch of Steem was reset due to an unexpected bug.
