Tempo’s ‘Zones’ sparks debate over privacy in crypto infrastructure

Tempo’s new “Zones” feature offers private, permissioned stablecoin transactions on its layer-1 for enterprises, but critics warn the operator‑controlled design adds back centralized trust.

Tempo unveiled a new “Zones” feature Thursday aimed at giving enterprises bank-style privacy on public stablecoin rails, but not everyone in crypto is convinced the trade-offs are worth it.
