How to prevent money laundering with blockchain

There are several use cases for blockchain technology when it comes to AML compliance and the fight against money launderers.

Immutable Ledger For Regulatory Oversight

The fact that blockchain technology uses a decentralized network, where each participant or node is required to validate changes, makes it incredibly secure.

Provided a hacker is not able to gain control over 51% of the nodes on the network, something which would require a supercomputer that does not yet exist, any unauthorized change would be automatically resisted by the other nodes.

Since each node has a record of the entire ledger, they are able to compare any change to their record and therefore detect any unauthorized change.

This particular aspect of blockchain technology means that blockchain ledgers can be completely trusted. Regulators would, therefore, be able to examine records knowing that the information contained within them was reliable and accurate.

Establish Trustworthy Identifications

Having an immutable ledger that records verified ID‘s of those behind each and every electronic transaction can act as a massive deterrent to money laundering.

Once again, since such a ledger would be unalterable, it would provide definitive proof in a court of law of a person’s or company‘s act to launder money.

Any blockchain-based database that involved money or property could be programmed to record a verified identification of each party for financial transactions. This would mean that these individuals could then be held accountable in the case of any financial crime.

Right at this moment, companies like Evernym, a startup that has developed its own blockchain, Sovrin, are racing to develop more secure ways of verifying customer identification.

Currently, the market relies on companies such as Equifax, which rely on client-server systems to maintain their databases.

In this interesting article, Vinny Lingham, CEO of Civic points out the problem of such systems; “These centralized databases are central points of failure for your identity.”

This gives the development of blockchain Customer Due Diligence (CDD) or know-your-customer (KYC) solutions a huge advantage over the systems currently in use.

Blockchain for AML Compliance Programs

The question of how to detect money laundering using blockchain technologies is a complex one.

Essentially, any deployment of a Blockchain-based AML solution would require the use/integration of smart contracts. 

A blockchain-based AML program that utilizes smart contracts would be able to use inbuilt algorithms to automate the process of AML regulations for fraud detection and combating money laundering.

By programming in a series of requirements, such as the need for verified ID, this technology would be able to automatically block or red flag any suspicious transactions.

In this way, it would be possible to gain oversight over all digital transactions made through participating financial institutions without having to hire huge teams of auditors to check the transactions and report suspicious activity.

Governments and law enforcement agencies would be able to implement a financial system making such oversight anti money laundering regulations, meaning that all financial institutions and cryptocurrencies would have to facilitate such a system in order to identify money laundering activities.

Such money laundering schemes would work by allowing each participating financial institution or treasury to act as a node on the blockchain. Whenever a transaction was made, it would be scrutinized by the network and could be flagged in the case that it was suspicious and needed procedures for money laundering investigations.

It can be argued that an integrated blockchain solution, where all the nodes are established financial institutions, is not in the spirit of the true decentralization concept outlined by Satoshi Nakamoto.  

However, the prevention of money fraud through money laundering activities, which cost governments 10‘s of billions of dollars in lost taxes surely has to be more important.

My Final Thought on Prevent Money Laundering Using Blockchain

All of this is exciting stuff. While the development of a ubiquitous blockchain solution that helps AML compliance officers to prevent widespread money laundering programs is still very far off, this new technology does have enormous potential to succeed where in the past we have failed.

Don’t forget that it was only after last year‘s cryptocurrency price spike that a vast amount of the new startups that are currently working on this problem were created. 

Examining some ICOs gives a good picture of just how much interest and innovation there is in this field.

Small-scale startups are tending to focus on solving smaller pieces of the puzzle. The work of companies like Evernym, for example, is already helping to solve the problem of ID verification, which is a major part of money prevention of money laundering.

When it comes to making a larger dent in the estimated $2 trillion that gets laundered every year, it is going to take the combined effort of governments and the entire finance industry as a whole to really solve this problem.

Given that some of these institutions have been found guilty of money laundering too, getting them to enthusiastically participate in developing a workable solution might be harder than actually developing the solution itself.

What is clear is that blockchain offers a chance to help put an end to, or at least massively reduce, a criminal activity that has been around for millennia.

Let‘s hope that blockchain can succeed where all others have failed.
