Network Congestion Impact
Network congestion impact refers to how high demand for blockchain transactions leads to delayed processing and increased fees, which directly affects the reliability of time-sensitive applications like oracles. When the network is congested, oracle updates may be stuck in the mempool, causing the data used by smart contracts to become outdated.
This creates a dangerous window of opportunity for attackers to execute trades based on current market prices that the protocol has not yet acknowledged. For derivatives, this can result in failed liquidations or inaccurate margin calculations.
Protocols must design their systems to be resilient to these delays, often by incorporating fallback mechanisms or prioritizing oracle transactions during periods of high network load.
