Halving day 2012 (November 28, 2012) was the day of the first subsidy halving, which occurred when block 210000 was solved. Until block 420000, the block reward would be 25 BTC instead of the original 50 BTC.

At the moment before the halving, there were 10,500,000 BTC in existence, 50% of the target cap.

Solution

Block 210000 was found and broadcast on 2012-11-28 at 15:24:38 UTC.[1] Slush's pool was responsible for finding the solution,[2] and a miner named laughingbear contributed the solution.[3]
