However, they also highlighted the susceptibility of such platforms to misuse by illicit actors.&nbsp;Tornado Cash faced legal challenges last year when it was accused of facilitating transactions for the North Korea-linked hacking group Lazarus.In response, the US Treasury Department's Office of Foreign Assets Control&nbsp;<a href="https://cryptonews.com/news/us-treasury-redesignates-sanctions-tornado-cash-crypto-mixer-citing-north-korea-involvement.htm">blacklisted Tornado Cash</a>&nbsp;in August 2022 due to its alleged involvement in illicit activities.By exploring the development of Privacy Pools, Buterin and his collaborators aim to address the concerns raised by Tornado Cash's legal troubles while advocating for a privacy protocol that aligns with regulatory requirements.&nbsp;&ldquo;In many cases, privacy and regulatory compliance are perceived as incompatible,&rdquo; the authors wrote.&nbsp;<blockquote>&ldquo;This paper suggests that this does not necessarily have to be the case, if the privacy-enhancing protocol enables its users to prove certain properties regarding the origin of their funds.&rdquo;</blockquote>Meanwhile, Buterin has recently admitted that centralization of nodes is one of the Ethereum network&rsquo;s biggest challenges, given the fact that the majority of the 5,901 active Ethereum full nodes are run on centralized platforms such as&nbsp;Amazon Web Services (AWS).The Ethereum mastermind said that he hopes in the future fully verified Ethereum&nbsp;<a href="https://cryptonews.com/news/vitalik-buterin-ethereums-future-upgrades-could-bring-full-nodes-mobile-devices.htm">nodes can &ldquo;literally&rdquo; run on a phone</a>.He claimed that solving the issue with centralization of full nodes is a &ldquo;big piece of the puzzle&rdquo; to making Ethereum more decentralized.
