Olympic Rewards Announced

Posted on .

ETH DEV would like to thank everyone for their participation in the Olympic test network, which helped us greatly in stress testing, optimization, and finding bugs in the Ethereum clients, as well as determining what the limits of the current Ethereum system are. To that end, we are pleased to announce the Olympic reward recipients. On top of the rewards announced below, every miner who mined a block in the Olympic chain with block number in the range [310000, 589999] is entitled to receive 0.5 ETH per block, and every miner who mined a block in the Olympic chain with block number in the range [590000, 999999] is entitled to receive 0.05 ETH per block.

Top miners for blocks 300000-1000000

To claim these rewards, send a transaction on Olympic from the address that earned the reward to your desired address.

Olympic blockchain is impossible to sync. Please, let me do the transaction on real network. All you need is the prove of me controlling the wallet. Why not in real blockchain?

    It’s not impossible. I managed to complete the whole process in a week.

come on, we have mined with 6 different addresses (never heard of block quantity competition) 🙂 we did 44k blocks in total – any chance to get 2nd 2nd place? 🙂

Pools is the centralization and intermediaries!
Where decentralization?

Bad block #1 (110bd75c06cba8fc7384b44cea4c122de0883d3ec5816e72d8a922f6b2282caa)

There must be a better way than for all of us to try to re-sync the old Olympic blockchain. This is becoming an impossible task.

I didn’t realize it was switched to 0.05 per block before I started mining. That text file is in wei right? Its not even worth it for me to get the olympic chain up for me to get the 2 ethers. 🙁
