Railgun has a loyal customer by the name of Vitalik Buterin, who has sent another 400 ETH worth over $1 million to the privacy-preserving crypto platform.
According to on-chain data platform, Arkham Intelligence, Ethereum co-founder Vitalik Buterin has transferred 400 ETH to Railgun. This brings the total to 662 ETH worth roughly $1.7 million at the time of writing.
Spot On Chain data shows that the funds were initially sent to an anonymous wallet before being sent to Railgun. It’s unknown why Buterin has decided to move another sizeable chunk of ETH to the platform.
Some seem to think the move is “suspicious,” but is it really? For one, Buterin is extremely wealthy, so perhaps obscuring some funds and their intended activities is a solid precaution. Furthermore, Buterin has publicly praised Railgun and advocated that “privacy is normal,” suggesting that the move may be more symbolic than anything.
Railgun hasn’t positioned itself as a crypto “mixer” akin to Tornado Cash or Samourai Wallet. A “true” mixer involves a user depositing funds, obscuring the token’s origins in the mixer, and then withdrawing them for the “privacy” to come into effect.
Railgun uses a “Privacy Pool” concept, drawn from Buterin’s 2023 academic paper on blockchain privacy. Essentially, it’s a private address system. The Privacy Pools use cryptographic proofs to verify the legitimate origin of funds and maintain privacy.
To get technical, it leverages Zero-knowledge proofs, specifically zk-SNARKs, to guarantee privacy. Each transaction enhances privacy by adding layers of random information to transaction details, making it even harder to trace its origins.
It effectively shields a user’s tokens so that all transactions appear as being sent/received by the Railgun contract address. The user’s tokens are private key controlled, meaning that the user can still use them for on-chain activities.
Both Railgun and Buterin claim that its system makes it “much harder” for hackers, fraudsters, and other criminals to join its Privacy Pool, but that may not be entirely true.
In 2023, research from financial crime compliance-centric firm Elliptic suggested that hackers had used Railgun. Worst of all, the North Korean hacking group Lazarus obscured tens of millions using the platform.
It was a small portion of the group’s broader series of hacks. They had primarily used Tornado Cash to wash stolen cryptos and launder their funds, but following sanctions against the mixer, Railgun became the main alternative.
The Lazarus Group was caught after then redistributing the funds to three exchanges. However, Binance and Huobi successfully identified, blocked, and seized these funds. To this day, Railgun denies that Lazarus leveraged Railgun in any way.
