<p>Has Ethereum become more centralized? The crypto community is sounding the alarm. Indeed, censorship is starting to gain ground on this very popular blockchain. Currently, 4 out of 5 of the largest “block builders” on the network are filtering transactions sanctioned by the U.S. government. Let’s take a closer look!</p> 
<h2 id="h-an-increasingly-centralized-ethereum">An Increasingly Centralized Ethereum</h2> 
<p>Vitalik Buterin was recently subjected to a public lynching while presenting the <strong>new Ethereum roadmap</strong>. Why attack such a Web3 icon in this way? In fact, he talked about a <strong>possible use of the UTxO (Unspent Transaction Output) approach</strong> to revise ETH staking. The blockchain he co-founded is so lacking in decentralization that it will have to borrow more innovative and decentralized concepts from other projects.</p>

<p>In a <a href="https://www.coindesk.com/tech/2023/12/06/ethereums-censorship-problem-is-getting-worse/?utm_source=twitter&amp;utm_medium=social&amp;utm_term=organic&amp;utm_campaign=coindesk_main&amp;utm_content=editorial" target="_blank" rel="noreferrer noopener">detailed report</a> focused on “<strong>Ethereum’s ‘censorship’ problem</strong>,” CoinDesk highlighted the <strong>disappointment of some researchers and users</strong> of the world’s second-largest blockchain. The reason: <strong>censorship is starting to make its mark</strong> on this network.</p> 
<p>According to the results of a study conducted by Toni Wahrstätter, a researcher at the Ethereum Foundation, 72% of the blocks of data displayed on MEV-Boost are currently being censored. As a reminder, MEV-Boost is the intermediary software powering the validators writing blocks on the Ethereum network.</p> 
<p>72%, that’s really alarming considering that <strong>Ethereum block builders only filtered 25% of transactions in November 2022</strong>.</p> 
<p>Among the 5 largest block builders of Ethereum, <strong>only “Titan Builder” disapproves of this practice</strong>. Martin Köppelmann, founder of Gnosis Chain, sounded the alarm by stating:</p> 
<p>“<em>If Titan started to censor tomorrow, <strong>Ethereum would be censored by more than 90%</strong>. So we’re only one constructor away from strong censorship on Ethereum</em>.”</p> 
<h2 id="h-ofac-in-action">OFAC in Action</h2> 
<p>The Office of Foreign Assets Control (OFAC) appears to be behind all this commotion. Indeed, by targeting Tornado Cash, with a lawsuit to boot, this branch of the U.S. Treasury Department has, in a way, put pressure on Ethereum block builders. It’s important to note this very important fact: Tornado Cash is an Ethereum-based “private mixing” program that allows traceless transactions.</p> 
<p>After OFAC decided to close down the tunnel through which stolen cryptos by North Korea’s Lazarus Group, as well as funds fueling terrorist organizations like Hamas or countries sanctioned by the United States such as Iran and Russia, transits. By adding the computer code of Ethereum-based Tornado to its blacklist, the U.S. regulator would have achieved its intended goals.</p>
