According to a report released by the EU, it explores the potential of permissionless blockchain in traditional finance (TradFi). The report suggests that permissionless blockchain should at least be considered as an option for traditional finance and financial market infrastructure. However, its adoption should be approached with caution. The author, Fabian Schär, argues that permissionless blockchains are more neutral than private blockchains, thereby encouraging competition. The unrestricted access provided by public blockchains starkly contrasts with the increasingly isolated private blockchains. Although public blockchains have their drawbacks, many well-known solutions can address these challenges, particularly by adding permissions at the smart contract level. The EU report does not shy away from discussing the disadvantages of public blockchains, such as scalability, privacy, finality, and governance. It delves deep into each topic, as well as the controversial maximum extractable value (MEV) issue, where block proposers sometimes reorder transactions at the expense of blockchain users, which is a form of front-running.
