Title: Data mining the blockchain Post by: agent13 on September 28, 2013, 01:31:36 AM The graphs here depict when newly generated coins first moved (up to block 250000). The Y axis is the mtgox weighted value for that day, with the X axis being the block number from where the coinbase originated. For example, X starts at block 9 which contains Satoshi's address 12cbQLTFMXRnSzktFkuoG3eHoMeFtpTu3S. These coins were first redeemed in block 170. We are not interested in block 170, but rather that it contains a transaction with an input from a coinbase.
Horizontal lines in the graph usually indicate redemption of coinbases within a single transaction (or nearby transaction/s). Redemption does not necessarily equal coin ownership, however coinbase spends are something I find interesting to plot. Density is difficult to display due to the size of the data set. The red selection (blocks 180000 - 220000, < $40) is shown in the second graph. It would appear that coinbases were redeemed more quickly from 2011 onwards. Perhaps this is due to pools having to pay their miners.
