Currently, two block builders, Beaverbuild and Titan Builder, dominate Ethereum block production. They hold approximately 88% of the market share, making the Ethereum network vulnerable to the risk of transaction censorship.

These attacks inflate asset prices to give users a poor exchange rate while profiting the validators.

A novel development by researchers at Paradigm allows dApp creators to tap into the lucrative MEV stream, traditionally only captured by blockchain validators.

Utilizing advanced MEV strategies, the bot turned a $66,000 investment into a massive $1.8 million gain.

With over 90% of Ethereum blocks now being built using MEV-Boost middleware, concerns over centralized block builders and increased transaction censorship have emerged. This shift challenges Ethereum's foundational principles of independence and decentralization.

In early April, a significant hack targeted MEV bots, resulting in the withdrawal of $25 million through an exploited vulnerability. Tether later took action by blocking the address of the validator responsible for the withdrawal.

MEV bot earned more than $1 million on successful arbitrage. But, almost an hour later, a hacker stole all the funds.
