The explosion of the privacy track in 2025 prompts a deeper reflection: privacy is evolving from an ideological stance into a genuine business necessity.

It seems that the trend is being driven by market momentum, and privacy technologies like ZK zero-knowledge proofs are indeed becoming mature and usable. But these are not the fundamental reasons. The real driving force is—without privacy measures, many businesses simply cannot operate. In scenarios involving stablecoin transactions, inter-company settlements, employee salary payments, and B2B payments, exposing data on the chain poses too great a risk to participants. Privacy needs have shifted from being an option for "capable individuals" to a mandatory requirement for "participants." This transformation signifies that privacy is no longer a niche topic but a demand at the infrastructure level.
