I know blockchain.info etc, but I'm looking for things beyond simple timelines of transaction volume and the like. I was thinking towards scientific projects that aim at discovering patterns in the historical data, for instance:
- are there addresses that accumulate large amounts of btc?
- are there interesting transaction pattern, e. g. prolonged transaction "ping pong" between address pairs, "star patterns" where a single address sends out transactions to a large group of others, etc
- are there amounts that seem to get passed on along a long chain of addresses?
Note that those are just examples I made up to illustrate what kind of angle I'm looking for: a more open-ended, scientific analysis rather than trading advice. That same notion makes it hard to search for projects, so I'm hoping that someone might happen to know something.
