Bitcoin UTXO Stats
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. The brighter the pixel is, the more unspent outputs/value it contains.
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.
