Hemi and Humanode Team Up To Take Down Sybil Threats
Humanode’s Biomapper c1 SDK is available on Hemi, making dApps and services resistant to Sybil attacks with secure biometric data.

Hemi and Humanode have teamed up to bring the Biomapper c1 SDK to Hemi developers. Humanode’s Biomapper is a key tool in preventing Sybil attacks, active across numerous chains, and is now available on Hemi.
With the Humanode Biomapper, Hemi developers can build Sybil-resistant dApps that ensure each user has only a single account without setting up invasive KYC procedures, for more secure gaming, DeFi, and general blockchain services.
Biomapper keeps users secure as well and does not store any images related to biometric identification; neither Humanode nor anyone else can access any of the private biometric data used to track proof of humanity for individual accounts.
To add Biomapper to your existing Hemi dApp or ongoing build, see the links below for a complete developer’s guide:
