Chainanalysis

[x3m]

It's a controversial topic and I'd like to dig more into it, to understand the current state of the art in terms of tools, processes and outcomes.
It's clear that the level of transparency in some blockchains like Bitcoin is more a bug than a feature.
I need your help to collect as many info as possible for an university assignment: tools, github repos, papers, websites, services, ...

Thank you.

I guess you think the transparency is not necessary (or is a problem) due to companies like chainanalysis. Assuming that's what you mean, I actually prefer service like that to be transparent before they are allowed on transparent networks. Decentralized Networks ought to be careful with centralized/opaque systems.

I think there are good reasons why satoshi and Co would want a transparent network, one of which is that Bitcoin is a public/open Network.  A public Network where Transactions is always available for anyone to verify.

Things could made more difficult for unsafe surveillance/tracking by improving on privacy/anonymity without compromising on other important features of Bitcoin like transparent, immutablity, etc.

Are you reffing to Blockchain Analysis or the company (https://blog.chainalysis.com/)? If you mean the company, you can see their blog (https://blog.chainalysis.com/). They regularly publicize their report.

But if you're referring to the task (Blockchain Analysis), you should able to find it on google with correct keyword. But here's an interesting paper, Anonymous Bitcoin Transaction. You also can find discussion started by the author at https://bitcointalk.org/index.php?topic=5117328.0.

What's the focus of your paper/assignment? As far as I can tell, a lot of tools don't explicitly stated that they're a chainanalysis tool. For example, walletexplorer, or blockchair can be used for chainanalysis but not exclusively created for that purpose.

Anyway, for chainanalysis service, you can take a look at https://partners.chainalysis.com/.

Blockchain analysis is big business, and all the major companies - Chainalysis, Elliptic, CipherTrace, etc. - will have their own methods and tools for doing so, none of which they will publicize. It all essentially involves linking addresses to each other through various transaction details, and then linking those clusters of address to real people because of KYC, publicly linking an address to their identity, spending habits, IP addresses, and so on.

You can read about all the ways addresses can be linked together here: https://en.bitcoin.it/wiki/Privacy
Blockchair give a list of how they link addresses together here: https://blockchair.com/api/docs#link_M6

Important to note that these techniques are not perfect, and can be fooled if you know what you are doing or rendered useless by mixing or coinjoining your coins.

First of all thanks for your replies. Keep it up!
 I need more advice and I'll try to be more specific.

The focus here is to describe the state of the art on both sides: from a chainanalysis perspective analyzing the tools and on the other side the regulators, law enforcement, etc.
I know that many companies have developed proprietary tools.
AFAIK chainanalysis is not performed on a blockchain, it's too slow and inefficient. GraphDB or other NoSQL DBs in synch with the blockchains are used to achieve a higher level of efficiency. 
Are there some papers, research, github repo, tutorials, speeches, ... to deepen my knowledge?
I don't deny that my final aim would be to propose the content for a chainanalysis course.
What would be in your opinion the structure of such course?
