XION introduces DKIM and ZK dual modules, becoming the first blockchain to store email authentication keys on-chain

BlockBeats News, February 11 — XION recently announced its new infrastructure and application scenarios. XION officially launched DKIM and ZK modules, becoming the first blockchain to store email authentication keys (DKIM) directly on-chain, and also the first consumer-grade L1 public chain to implement zero-knowledge verification at the protocol layer.

XION pointed out that existing email verification solutions (including projects like zkEmail) rely on centralized DNS servers to obtain encryption keys. When email providers rotate keys, the old verification becomes invalid, and there is no historical record to trace. XION’s DKIM module permanently stores these keys on the blockchain state, completely eliminating dependence on centralized DNS infrastructure. Its ZK module implements zero-knowledge proof verification at the protocol layer, with an efficiency ten times that of smart contract solutions. Working together, they enable users to prove any information in an email without revealing the email itself.

XION stated that approximately 61% of employees who witness misconduct remain silent, as traditional options are often “anonymous but ignored” or “speaking out but risking job loss.” With the above infrastructure, XION has enabled various application scenarios, including:

Anonymous reporting and workplace evaluations (proving employment status without exposing personal information)

Wallet recovery without mnemonic phrases (using email as backup keys)

Purchase behavior and certificate verification (without excessive personal data sharing)

Trustless ticket resale and insurance claims, among others.

Upon launch, it supports Gmail and Apple Mail, covering about 3.8 billion email users worldwide (over 90% of the global email market). Currently, XION’s platform has over 800,000 monthly active users, with more than 150 brands including Uber, Amazon, and BMW integrated. The official said this is a verification infrastructure built for the existing internet, “able to verify anything with zero information leakage.”
