What credible education could I do that is shorter than a master's degree on Ethereum/blockchains? I don't hold a CS degree but an econ bachelor (and business MSc).

I'm looking for ways to meet people that are interested in crypto and also to get some sort of certification that could open up doors for me to enter the space. Currently, I'm teaching myself how to code. I'm beginning to dig into solidity after focusing on javascript-based app frameworks. So I'd love to do a certificate that is somehow technical.
