What is Linen™?

Linen is a distributed registry of cryptographic private keys that are created and protected using audited security procedures.


High Integrity Private Keys

Private keys are a foundational piece of cybersecurity.  They are used in SSL certificates, API keys, and crypto wallets.  Private keys registered on Linen™ are created and protected using processes audited by Linen™ authorized assessors.


Secure Infrastructure

Each private key is represented by an address that is a hash of the public key. Data is stored in an integrity-protected and immutable blockchain that uses battle-tested Byzantine-fault tolerant consensus protocols.


Usable Security Data

Private key security properties are recorded in an easily comparable standard format.  The data is accessible via APIs so communication endpoints can query this information and perform safe and automated trust decisions.

Securing the distributed energy supply chain

The SunSpec Alliance created the Blockchain Work Group to make Linen™ an industry standard.  Join us and contribute.
