There are a number of wallet explorers that tag which Bitcoin addresses belong to semi-major sites/exchanges/ect, I don't see why someone couldn't do a similar analysis for CLAMs or at least for their CLAM addresses. I wouldn't think it would be difficult to find the majority of their CLAM addresses with blockchain analysis.
That's a good idea. Any idea whether any of them are open source or open to adding new coins?
None of the CLAM block explorers that I am aware of do the address clustering / labelling thing.
I don't believe that they are open source, and it is possible that they would be open to adding new coins. The one that I primarily use is walletexplorer.com. The owner/dev of walletexplorer appears to be and his email address appears to be "ales.janda zavináč kyblsoft.cz" which I would presume would translate to
ales.janda@kyblsoft.cz however I am not certain.
Depending on how much volume goes to their site, and if there are any coin-join like services for CLAM, it might be possible to to a spend-link analysis manually with the address provided by the OP. However even if it were to be assumed that the address in question belongs to Bittrex, I am not sure what exactly the next step would be, as AFAIK they do not require any kind of identity verification so someone could potentially create a brand-new account to deposit funds to then sell the CLAM for something like bitcoin-dark and/or bitcoin (and use a mixing service and/or coinjoin service) which would make it nearly impossible to trace the coins.
and the guy is really nice and helpful. He implemented some tips i gave him pretty fast and other things.
Im sure he will help you setting something up, though i dont know if there is a free script of that kind somewhere.
