Explore how the Condorcet paradox exposes the limits of perfect fairness in blockchain consensus. For decades, research in distributed systems, especially in Byzantine consensus and state machine replication (SMR), has focused on two main goals: consistency and liveness. Consistency means all nodes agree on the same sequence of transactions, while liveness ensures the system continues to add new ones. Still, these properties do not stop bad actors from changing the order of transactions after they are received. In public blockchains, that gap in traditional consensus guarantees has become a serious problem. Validators, block builders or sequencers can exploit their privileged role in block ordering for financial gain, a practice known as maximal extractable value (MEV). This manipulation includes profitable frontrunning, backrunning and sandwiching of transactions. Because transaction execution order determines validity or profitability in DeFi applications, the integrity of transaction ordering is vital for ...
United States President Donald Trump has been talking up the prospects of Saudi Arabia agreeing to normalise ties with Israel, but it is unlikely to happen when Saudi Crown Prince Mohammed bin Salman visits the White House this month. The establishment of diplomatic relations between Israel and Saudi Arabia after decades of enmity could shake up the political and security landscape in the Middle East, potentially strengthening US influence in the region.
