Many people think that institutions don't dare to use Ethereum because of its high volatility or strict regulations. Actually, that's not the case. What truly holds them back is the architecture.

Traditional financial institutions' systems are inherently built on the assumption that everything is "restricted and visible": layered permissions, internal audit channels, controllable data surfaces, and invisible internal flows from the outside. Public blockchains default to open execution, which directly reverses their underlying logic. The real contradiction has never been "privacy versus liquidity," but rather: can they maintain confidentiality without sacrificing Ethereum's final settlement?
@zksync's Prividium isn't really solving this as a scaling problem but as an infrastructure layering issue. Execution and state remain within environments controlled by the institutions themselves, so data doesn't become "public infrastructure." However, each batch commits cryptographic proofs to @Ethereum, enabling verifiable settlement without revealing all operational details. This effectively separates "execution confidentiality" from "settlement trustworthiness."
Selective disclosure transforms from a "special approval process" into a programmable feature. Want regulatory proof of a specific workflow? It can be provided. The entire market doesn't need to watch your internal processes. Liquidity isn't lost because Prividium natively interoperates with the ZKsync network, with assets always anchored on Ethereum rather than stuck in a small consortium chain.
It's neither a private fork of Ethereum nor just grabbing blockspace on any L2. It extends Ethereum's trust layer, within scope, to environments where "visibility must be controlled."
In short: it's not about bringing institutions onto public chains, but precisely delivering Ethereum's final settlement capability right to their doorstep without exposing their entire bottom line. This approach is quite ruthless and clever.
