Zero-knowledge tech is way more private than optimistic tech. This is exactly we’re seeing more ZK development on Ethereum

This doesn’t mean that optimistic tech is bad. On the contrary, as opposed to what many think, optimistic tech will ALWAYS be an important and integral part of Ethereum and will never go away. However, it does lack a little when it comes to privacy. Compared to zero-knowledge, optimistic tech isn’t as private considering that validators have access to the information related to you/your transactions. This isn’t the case with zero-knowledge. Validators have the minimal needed amount of information needed to validate a transaction in a way that can’t be linked to you as a person, hence the name “zero-knowledge” because all transactions looks the same to a validator, they just have to confirm if the transaction is valid or not. Zero-knowledge doesn’t only stop at crypto transactions though. Some platforms like Polygon took it a step further and integrated into identification through Polygon ID. Its currently a bit difficult to prove your identity without having to disclose sensitive information. But zero-knowledge solves that. With ZK-proof any user can prove that “yes this is me” without having without having to disclose personal information. This is a HUGE use case that crypto projects can benefit from as there’s still no solutions for this problem outside of the crypto space and this is exactly what Polygon is capitalizing on with Polygon ID. You can literally use it verify your identity anywhere from Metaverse ecosystems, real world business, social media, Fintech services and platforms that require KYC. You know what this means right? With Ethereum being famous for extreme secure, zero-knowledge will soon attract institutions and businesses into the crypto world bringing a ton of new money into the market and more specifically Ethereum!
