It's been around a while now, but just in case you haven't seen it, Transaction Street is a fun vizualisation of the transactions going (or not going) through various blockchains in real time.
You can compare blockchains like in the screen capture below, which shows ETH on the left and Bitcoin on the right, or you can simply select one chain to view at a time, personally I prefer the comparisons, as two fit perfectly well on one screen.
It's wonderfully simple yet powerfully explanatory which any good Viz should be -
- The carriages in the middle show the blocks
- The people are the transactions - you can see them entering one block and getting booted out to the next on ETH, presumably as new txs offer up higher gas fees.
- And on the left (of the ETH VIZ) you see where the txs are coming from - Uniswap, Axie and so on.....
And there's a stack load of further info to check out too!
It's a great way of seeing what the median ETH fee is and how congested the network is!
