Is there a way to create portfolio for web3 generalist?

On one side you cannot trust the existing professional profile on the other there is no legitimate way to show a body of work(off-chain contribution like content, marketing, design etc.) and explore opportunities in web3. On top of that professional employment and skill verification are expensive for organizations. I was wondering if we could crowdsource proof of work/employment/skill verification to create a comprehensive portfolio for anyone. Blockchain ecosystems make sense because incentivisation cryptographic proofs are a norm there
