Interview question EVM · Solidity timestamp manipulation · Need Practical mitigation tips
How can I really prevent timestamp manipulation in a Solidity auction during an Interview question EVM scenario?
I froze in a technical round when the interviewer drilled into how miners might nudge block.timestamp
to stretch or shrink an on-chain auction window . Using block.number
isn’t bullet-proof because block time isn’t constant , and pulling a Chainlink feed felt like overkill (plus gas) .
Here’s where I’m stuck — any sharp, production-tested answers?
Is a simple commit–reveal scheme enough, or should I add a grace period buffer for bids?
Does OpenZeppelin’s TimelockController help here, or is that more governance than auction?
Have you balanced gas efficiency with fairness using fallback timing checks or circuit breakers?
If you’ve faced this exact Interview question EVM, what response earned you bonus points?
I’d love concise code snippets, whiteboard-friendly explanations, or even horror stories from mainnet deployments . Anything that turns this gotcha into a confident answer for the next EVM security interview would be amazing 🙌
Thanks in advance — your insights could save my next Interview question EVM moment!
