XION launched DKIM and ZK dual modules, becoming the first blockchain to store email authentication keys on-chain
XION recently published an article introducing its new infrastructure and application scenarios. XION announced the official launch of the DKIM module and the ZK module, becoming the first blockchain to directly store email authentication keys (DKIM) on-chain, as well as the first consumer-grade L1 public chain to implement zero-knowledge verification at the protocol level.
XION pointed out that existing email verification solutions (including projects like zkEmail) rely on centralized DNS servers to obtain encryption keys. When email service providers rotate keys, the old verifications become invalid, and there are no historical records available. XION's DKIM module permanently stores these keys in the on-chain state, completely eliminating the reliance on centralized DNS infrastructure. Its ZK module implements zero-knowledge proof verification at the protocol level, achieving an efficiency that is 10 times that of smart contract solutions. The two work together, allowing users to prove any information in an email without exposing the email itself.
XION stated that currently about 61% of employees who witness misconduct remain silent, as traditional options are often "anonymous but ignored" or "speak up but risk unemployment." With the above infrastructure, XION has realized various application scenarios, including:
- Anonymous reporting and workplace evaluations (proving employment status without exposing personal information)
- Wallet recovery without mnemonic phrases (using email as a backup key)
- Purchase behavior and certificate verification (without excessive sharing of personal information)
- Trust-based ticket resale and insurance claims, etc.
It supports Gmail and Apple Mail from launch, covering approximately 3.8 billion email users globally (accounting for over 90% of the global email market). Currently, the XION platform has over 800,000 monthly active users, with more than 150 brands including Uber, Amazon, and BMW already onboarded. The official statement claims this is a verification infrastructure built for the existing internet, "capable of verifying anything while leaking zero information."
