The narratives surrounding Tornado Cash


It has been about 2 weeks since Tornado Cash was sanctioned by the U.S. Treasury’s Office of Foreign Assets Control (OFAC). This sanction came as a reaction to the notorious North Korean Lazarus Group using Tornado Cash to mix Ethereum deposits and launder more than $455M from the Ronin Network attack as well as the Nomad attack. There are several narratives that have developed since the sanction, and we are going to distill the few that raise questions about the future of a decentralized and open internet.

Firstly, let’s address the question of free speech. 29 year old Tornado Cash developer Alex Pertsev was arrested on August 12th by the Netherlands government on suspicion of fraud, environmental crime and asset seizure. The tech community world over has mobilized against this action by releasing petitions and grants to help free Alex, but the larger question that remains is of free-speech. Is writing code a crime? Additionally, Microsoft deleted accounts of Tornado Cash contributors on Github rendering 30 years of legal work to establish first amendment protections around software distribution obliterated by Microsoft in a day - notes Johns Hopkins cryptography professor Matthew Green. Considering Tornado Cash is an open-source software, and not centrally owned, action against the platform rather than the smart contracts seems like the easy way out.

Second, the boundaries of compliance and the thin line between censorship and protection. Coin Center analysis of the Tornado Cash sanction notes “by treating autonomous code as a person OFAC exceeds its statutory authority”. Coin Center discussed the case of Blender a Bitcoin based cryptocurrency mixing service and how Blender could choose to deny a request to send funds, or even have lawyers represent the entity in the court, therefore rendering it as a ‘person’ which would entail fair jurisdiction on OFAC’s behalf. Tornado Cash on the other hand is not a company, or entity, but was treated as such. The addresses present in Tornado cash are arguably governed by people, but the platform itself is not centrally owned. So, how is regulation going to govern something that is not owned by individuals? More importantly, what does the stance of the government on open source software say about its interests in protecting free-speech?

Lastly, factions within the web3 community of blind compliance and those against. Major organizations in the web3 community such as Circle and Ethereum miner Ethermine have taken a stance to block Tornado Cash transactions alongside FTX, who is blocking Aztec Network which has been labelled as a mixer, whose services are being considered as ‘high-risk’. Circle froze 75,000 USDC worth of funds linked to Tornado Cash’s sanctioned addresses, and Ethermine, one of Ethereum’s largest miners, no longer produces blocks containing Tornado Cash transactions. From the organizations’ perspective, these actions are a risk mitigation strategy in the case the government decides on shutting down their respective services, but it is coming at the cost of keeping the internet a free-flowing space.

In conclusion, the events that are going to transpire with Tornado Cash are pivotal in determining the course of freedom on the internet. Whether you are a part of the web3 ecosystem or not, digital sovereignty is going to impact you in some shape or form. What’s left to see is how, open source software and self-custody solutions react to the coming regulations in protecting promoting a more open internet.

Proof-of-Skill: Consensus through skill validation


Sure, no one lies on their resume. Right?

The Proof-of-skill idea is born out of the belief that credentials from centralized institutions are not a conclusive indicator of the skills an individual possesses. Additionally, learning takes place in a decentralized manner - from Youtube channels, online code repositories, Wikipedia, Twitter etc. Today’s education is vastly spread out across various means, and therefore, organizations also struggle in verifying the claims of an individuals knowledge and skills.

Proof-of-skill is a decentralized credentialing protocol where industry experts aka skill validators provide proof-of-skill Soul Bound Tokens (SBTs) to candidates by building consensus for the skills they possess. The project is currently under development and is looking for contributors, so if education is a passion of yours, reach out to us, or the founder Raj Desai, and help make Proof-of-skill a reality!
