Visualization of the unspent transaction outputs in the Bitcoin Blockchain

This is a website I created just for fun to visualize the distribution of the unspent transaction outputs (UTXO) in the Bitcoin blockchain.

Each pixel in the images represents one block. So the first pixel (counted left to right from the top) is the genesis/first block. If you hover over that pixel in the first image (orange), you'll see that it has a block height of 1, and 1 unspent transaction output in it. If you hover over the same pixel in the other image (blue), you will see that it has a combined value of 50 BTC.

So by looking at these two images, you can see how the UTXOs ("coins") are distributed over the whole blockchain. You can also see where most of the value is stored with the blue image.

Naturally, a lot of the "coins" and its value are concentrated at the end of the blockchain. But it's also possible to see that there's a lot of unspent coins in the blocks of early 2013. The same applies to the blocks in mid 2015.

Let me know if you have any questions :)
