My worst production scare happened during a liquidity-pool upgrade. A junior thought the pool was stuck, so they instantly suggested redeploying the contract. Turned out the keeper script had stalled, nothing on-chain was actua...

How to Explain Blockchain Projects in Interviews (So Recruiters Actually Understand Them)
I had the exact same problem in recruiter screens — the moment I said “smart contracts + IPFS” their eyes glazed over 😅 What helped was making two versions of the same project explanation: 30–45 sec (non-technical...

4 years as a Salesforce dev — should I jump to Solidity now, or keep Salesforce as my safety net?

I’m interviewing for US remote Solidity roles and keep getting a Solidity take-home assignment instead of a live coding round. The part I’m stuck on isn’t “can I finish it” — it’s what they actually grade. Typical prompt: implement a small...

Do AML and crypto compliance professionals need to understand ERC-3643 for RWA tokenization roles?
What I am noticing in recent RWA discussions on LinkedIn is that the conversation is slowly moving away from “tokenize everything” and more toward “who can verify, restrict, monitor, explain and defend the asset movement when the asset is r...

Recruiters: how do you verify real blockchain experience before the interview?
I’d be careful not to turn “verify blockchain experience” into a hunt for perfect GitHub activity. Some strong candidates have private client work, closed repos, or protocol contributions that are not easy to show publicly. What I usually l...

How do you prevent block.timestamp manipulation in Solidity smart contracts for time-sensitive auctions?
The interview version can be very simple. I would say: “You do not fully prevent timestamp manipulation. You reduce its impact by making sure a small timestamp shift cannot decide the auction.” So I would use block.timestamp for rough deadl...

How do you prevent block.timestamp manipulation in Solidity smart contracts for time-sensitive auctions?
One small distinction matters here. Commit–reveal does not really “fix” timestamp manipulation. It is more useful when you want bid privacy or want to reduce front-running pressure. TimelockController is also not the main answer for auction...
