Using the mempool.space API we can quickly fetch the most recent 99 blocks, and display useful information about recent blocks at a glance using a new visualisation approach.

Miners

We can colour code each block based on which miner found it, giving us a nice visual representation of the last 16h or so of blocks.

Mining Proxies

There is much debate and discussion around common block templates and possible proxy pools. For example, a quick look at the mempool stratum job visualiser at any random time will reveal that bunch of pools all sending the exact same set of transactions. We might want to see what the impact on block template diversity is if this example set of miners were acting as single group.

> Warning - A snapshot is not proof of a common template issuer - common tx sets in templates can occur naturally when the "churn" in the set of transactions in the next mempool block template is low (e.g. when there isn't much activity, especially just after a block was mined). For example see this screenshot below.

To explore the effect of a group, you can go to grid.orange.surf create a custom group, give it a name and select a custom colour for your group.

The block colour and legend auto update as you make changes, and all the info is stashed in the URL so you can easily share the link, this link

Make your own groupings and share them in your blog posts on proxy pool speculation!

Other Data

We can use this same visual approach to show other data at a glance

Fees

We can display the median fees rate, in this case we see that the recent fees have been low (5 sat/vB) with only occasional blocks with an elevated fee.

## Transaction Count

Next we have the number of transactions per block.

Block Weight

Other Features

Hover

On desktop we can hover over a block to see more information, such as the block height, the miner name etc. and clicking on the block opens it in mempool.space for deeper review.

If you enjoyed this and find it useful zap me some sats to buy me a coffee to keep adding new features like long-term visualisation of thousands of blocks and sorting by clusters.
