3.4.3 MEV-Resistant Design

MEV (Maximal Extractable Value) is a "pain point" in crypto transactions - hackers use methods such as "front-running" and "sandwich attacks" to profit from user transactions, which has a particularly great impact on large transactions. Oasis DEX solves this problem through a "cryptographic lottery" mechanism:After all pending orders enter the "pending matching pool", the system randomly disrupts the order of the orders through a cryptographic algorithm, and the matching results are only made public after the transaction is completed;Before the transaction is confirmed, no one (including verification nodes and aggregators) can predict the order of order matching, completely eliminating the possibility of "front-running" and making every transaction fair and just.
