24 Hours on the Blockchain

This is a visualization of one day's activity on Bitcoin's blockchain. The visualization runs from block 210,000 to 210,165 (the twenty-four hour period following Bitcoin's first "halving event").

Each frame represents one block with the block number or height at the bottom right. Each circle represents a transaction. The size of the circle is proportional to the number of Bitcoins transacted. The circles are color coded as follows:

• If the circle is green, the transaction is part of the block.
• If the circle is red, the transaction is part of a previous block but at least one of its outputs are redeemed by at least one transaction in this block.
• If the transaction is blue, the transaction is in a future block (at the time the visualization was generated), but redeems at least one output of at least one transaction in this block.

A directed arrow represents a flow of Bitcoins from the output of one transaction (at the source of the arrow) to the input of another (at the target of the arrow).
