Interview Question: How Do You Ensure Data Integrity Before a TEE on Ethereum?
How do you ensure data integrity before information enters a Trusted Execution Environment on Ethereum?
I got this question in a recent blockchain developer interview and it threw me off. I know TEEs protect data once it’s inside, but how do you prevent tampering with the data during transit? If the data gets altered before reaching the TEE, the smart contract’s security could be compromised.
Has anyone tackled this interview question or solved this in a real blockchain project?
What tools or methods have you used to validate or secure data before it enters the TEE? Real-world examples from Ethereum or similar blockchain setups would be really helpful.
