Miner Extractable Value (MEV) poses serious risks in blockchain systems by allowing miners preferential access to complex contracts, which can undermine decentralization and censorship resistance. Traditionally, miners earned revenue from block subsidies and transaction fees. However, with the rise of intricate contracts, miners can jump the queue when executing trades, thus concentrating wealth and power. This increasing complexity leads to significant centralization pressures, making it challenging for the ecosystem to maintain its foundational ethos of fairness and resistance to censorship. Ethereum has been especially affected by this phenomenon, leading to proposals like Proposer Builder Separation to address the issue.
Miner Extractable Value (MEV) creates significant risks in blockchain systems as miners can prioritize their own transactions, undermining the trust in decentralized networks.
The complexity of contracts and protocols on blockchains increases the potential for centralization among miners, who can exploit their unique position for profit.
