Fighting Bitcoin Theft - Police Describe Enforcement Block Explorer
Recently I had a chat virtually what would hold upwards some expert features for a block explorer to have. One affair I don't actually meet implemented likewise good is a tool for helping care the theft of bitcoins. The persuasion isn't anything novel actually - I discussed something similar dorsum inward 2013 - a block explorer focused on tracking officially reported thefts of coins as well as providing a tools for exchanges to cross-reference their inputs alongside the database. Here is how it could work...
The tracker would essentially hold upwards a block explorer focused on tracking money taint - goose egg solid set down breaking there. However, if yous dyad that alongside allowing police push clit enforcement from roughly the the world submit precisely which coins they desire tracked, it tin terminate dice a character tool for figuring out whether some coins are "tainted" or not.
However, the taint shouldn't hold upwards permanent. If the stolen coins are recovered, or they halt upwards real diluted inward a legitimate house of business, the outputs mightiness ask to hold upwards whitelisted equally "clean" to halt the tracking. This way, the coins could dice dorsum into circulation without triggering whatever to a greater extent than flags inward the future. This whitelisting procedure should also hold upwards carried out on asking of the police push clit enforcement.
The argue why nosotros would focus on police push clit enforcement is to confine the amount of simulated claims of thefts. If somebody actually lost their coins, rather than solely claim to induce got lost them, they wouldn't heed filing a written report as well as beingness liable inward illustration they lied. Similarly, when tainted inputs are reported but they are deemed likewise diluted past times whoever is responsible for the local AML enforcement, they would hold upwards the ones responsible for that decision.
Knowing which outputs to track, the residuum is piddling - follow the coins each fourth dimension they are spent, dice on a rails of how the taint mightiness hold upwards diluted downwards the line as well as tape everything for afterwards reference.
Any transaction that contains tainted coins could hold upwards reported to the authorities, or at that spot could hold upwards a threshold of the minimal taint for reporting (say, inward a higher house 10%). Depending on the regulations, the coins would either ask to hold upwards frozen past times the exchange, or if the taint is small, the regime could whitelist the transaction on the tracker.
As alongside many things Bitcoin, the solution is non clearly expert or bad. On the positives, this tin terminate discourage people from stealing bitcoins equally they would induce got much harder fourth dimension spending or converting them (who knew infinitely traceable currency tin terminate hold upwards as well as thus difficult on criminals?). As for the negatives:

The stolen money tracker
The tracker would essentially hold upwards a block explorer focused on tracking money taint - goose egg solid set down breaking there.

Who is going to purpose this?
Any companionship that is required to follow AML regulations, similar whatever Bitcoin exchange, would desire to commencement using the service to brand certain they are non liable downwards the line. The exchanges would either desire to inquire the tracker virtually every deposit they have to cheque its taint, or if they are real privacy conscientious, they mightiness only desire to poll for whatever recent movements of tainted coins as well as exercise the cross-referencing themselves.
Any transaction that contains tainted coins could hold upwards reported to the authorities, or at that spot could hold upwards a threshold of the minimal taint for reporting (say, inward a higher house 10%). Depending on the regulations, the coins would either ask to hold upwards frozen past times the exchange, or if the taint is small, the regime could whitelist the transaction on the tracker.
The implications
As alongside many things Bitcoin, the solution is non clearly expert or bad. On the positives, this tin terminate discourage people from stealing bitcoins equally they would induce got much harder fourth dimension spending or converting them (who knew infinitely traceable currency tin terminate hold upwards as well as thus difficult on criminals?). As for the negatives:
- We would hold upwards dealing alongside many jurisdictions alongside dissimilar laws, making the blacklisting as well as whitelisting procedure complicated
- This persuasion may Pb to the Bitcoin redlists, where all coins would hold upwards considered tainted unless they were whitelisted - clearly non a desirable path for Bitcoin to hold upwards heading
- The tracker would solely hold upwards useful if a lot of international Bitcoin exchanges would pick out to purpose it. Having a few big exchanges ignore it completely would only hateful everyone alongside tainted coins would only watch them instead circumventing the tool
- This tool would negatively touching on Bitcoin fungibility, which makes the arrangement less desirable overall
- A lot of independent vendors as well as casual users accepting bitcoins wouldn't hold upwards able to effectively written report all suspicious activities, perhaps forcing them to switch over to using big payment processors instead, going against the Bitcoin persuasion of beingness one's ain bank
Conclusions
All inward all, exercise the benefits outweigh the drawbacks? Possibly. Then again, if somebody that understands Bitcoin won't create a tool similar this as well as run it responsibly, nosotros mightiness halt upwards alongside somebody from exterior that doesn't know how the Bitcoin ecosystem operate come upwards inward as well as forcefulness something worse upon us...
