Multi-Block Verification

Multi-block verification is a security strategy that requires a trade or protocol action to be validated across multiple consecutive blocks before it is finalized. This adds a layer of time-delay, making it nearly impossible for an attacker to exploit a vulnerability in a single transaction block.

For example, a protocol might wait for three blocks to confirm a large withdrawal or a significant change in a liquidity pool. This delay allows the protocol's monitoring systems to detect and block suspicious activity before it becomes irreversible.

While it slightly increases transaction latency, the gain in security is substantial. It is a proactive measure against complex, multi-stage attacks in the blockchain ecosystem.
