On-chain investigator eyeonchains debates whether zero-knowledge privacy makes life easier for criminals. The clip weighs the rights of ordinary users against illicit finance and the tools investigators still have. Recorded at ETH Tbilisi 03. The discussion follows the investigator's main session on radical transparency at the same meetup.

Do you think generally as this technology is progressing is your job as an open-source investigator is it getting easier or is it getting harder? What I mean is that do the c is the criminal's job getting easier or is it getting harder? uh it will getting depends in which case because uh nobody taking um taking uh what what I can explain it so nobody um taking attention what about what they're doing so uh if someone is very uh expert and so it's not a new beginner on blockchain for sure it will use

something of strong project or that's for hide this transaction and uh if it's if it's he did something of wrong but um the fact it's uh if you will use um the the new projects they are in common it will be a little bit hard to for me for for track for for tracking depends in which case we talking about because there are many cases where it was um like very uh difficult to to track uh the individual even also using in the same time to cash

uh it was a little bit uh easy for me for bypass it uh for um for track the the depositor address but um if it's someone very practiced with um [clears throat] uh with the blockchain so be very easy for for him hide so you can do infinite transaction for for I do but people doesn't have um I don't know practice or um big intention to do something of complex to to to to hide the transaction. So they they prefer to use the uh as people strategy. So like

using a tornado cash or um brave gun or uh two or three layer of uh depositing inside this type of dubset then withdraw the money long term. >> Thank you. Uh what is your advice for beginners who want to get into open source intelligence? What should they use? what type of things that they should practice and how generally what should be their mindset if they want to get into open source intelligence.

So uh for sure you you need to be a guy very um enthusiastic uh about uh research because uh you need to be very curious guy um looking uh the source of the information because that's that it was my my that the things uh given to me very simple to be a open source researcher and onchain analyst Um and so you need to be practice with the Google darking because it's the main technique I'm using for find info. Um when I got something of interest from onchain part

then you you need to use so many toolkit you you need to be you need to be skilled with development build something um helping to you um giving to you a easy way for um reducing the time uh about your research. >> Uh so when you're working you're dealing with a lot of data, transactions, addresses, right? So what are some softwares that you use to first of all to collect this data to visualize this data and to use it to better understand things so to say. uh I'm using tool kit

to my toolkit it's like um I'm using like um Arcom chain analysis meta metas layouts uh so they are the main uh onchain platform you can use for um create cluster about the wallet activity uh for track every single um information related on the onchain part and about the offchain part the my my toolkit it's it's a bit long but I can mention like uh Intelix is the biggest data uh data bridge where they have inside like 40 billion data records I think um then big

peak um there are only toolkit um um you can use for cross check the information you got from the onchain then try to to match uh about the individual. Um other toolkit very very good uh very useful is OCT industries.
