I don't know what you want to analyze, so I'm putting a serie of resources that I use in case I feel more curious about it.

This is by far the best blockchain explorer and I'm not talking about just the API and open-source..I'm talking about design, it's very easy to show, have lots of useful data and of course, you can check everything.

Level: for begginers, this would be fine

When I try to explain my friends the inside part of a transaction, I use this tool. It's excellent and the crown jewel for me is these little babies called privacy analysis and Tx fee which tells you how much you overpaid for your tx. The privacy analysis allowed me to learn about my privacy mistakes.

Level: for intermediate users or when you're trying to explain how much exposé your tx have with the world.

For me, this is by far, the best tool. Not only you can add notes and share your knowledge with others but also have some helpful statistics and graphs that helps you to interact in a beautiful way with the blockchain explorer. If you have a fixation using timestamps as a resource for analysis, for instance, let's see what we have

What I like to do is go to latest annotations and check what are people working on and join if I understand the work. As a matter of fact, one of my favorite onchain analysts which I highly recommend is ErgoBTC, he uses lots of OXT resources to make his analysis. Oh oh, we're not even talking about the magic of the graph if you want to make a connection.

Level: intermediate user, I mean, I even think people with basic stuff can handle this but requires a little of more...time.

It's always a good tool, it's just..too much noise for me. But it's something personal.

Any blockchain explorer.

I like mempool.space
