In Bitcoin mining the miner of a new block is rewarded with newly generated Bitcoin. The amount of this mining reward is decreasing over time until all 21 million Bitcoins are mined. Until then each block in the Bitcoin blockchain contains a special transaction called the boinbase transaction which assigns the new Bitcoins to the miners address. Part of each transaction are so called input and output scripts enabling various functionalities. Some miners use the input script to encode messages. This dataset contains the input scripts of the coinbase transactions in HEX format. Decoding the right scripts will reveal the messages encoded in there. Have fun ;)
