Storing email authentication keys (DKIM) directly on the blockchain, XION announces the official launch of the DKIM module and ZK module.

Odaily Planet Daily reports that XION has officially launched the DKIM module and ZK module, serving as a blockchain that directly stores email authentication keys (DKIM) on-chain, implementing zero-knowledge verification at the protocol layer for a consumer-grade L1 public chain.

XION points out that existing email verification solutions (including projects like zkEmail) rely on centralized DNS servers to obtain encrypted keys. When email providers rotate keys, the old verifications become 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 states that currently about 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 infrastructure described above, XION has enabled various application scenarios, including:

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

Wallet recovery without mnemonics (email as backup key)

Purchase behavior and certificate verification (without excessive sharing of personal information)

Trust-based ticket resale and insurance claims, among others.

Currently, XION has over 800,000 monthly active users, with more than 150 brands including Uber, Amazon, and BMW integrated.
