Mapping Real Identities to Blockchain Identities

Peer Ledger provides the missing piece for digital identity on the blockchain. Blockchain apps now use pairs of public and private keys to verify identity. But no mechanism can prevent a user from setting up a blockchain account and linking any identity to it. We solve that problem by using real identities to make sure blockchain identities are accurate. Leveraging off-chain PKI certification, we enable multi-factor authentication, revocation, delegation, and data governance at scale.

Blockchain Platform Agnostic

You can use Peer Ledger’s solution with all forms of blockchain. We provide an identity management bridge between PKI infrastructure and Ethereum and Bitcoin fabrics. Our bridge to Hyperledger is coming soon.

With a few lines of code, a blockchain application can get a PKI-based auth service. BIT is our Blockchain Identity Translation service.

BIT.authenticateWithPopUp().then((result) => {
// An access token associated to the user account
const token = result.token.accessToken;
// The authenticated user’s account information
const account = result.account;
}).catch((error) => {
// An error occurred in authentication

Users self-serve to do password, pin, pattern, and certificate resets.

Users can select their own password, pin, pattern, and certificate resets. This feature reduces costs for the organization. The total cost of our identity solution for blockchain is relatively low. Yet we provide the best user experience available while we strengthen the security of blockchain applications.

It’s possible to set up a separate Registration Authority (RA) solely for blockchain applications, but it is expensive and duplicative. Our solution is much easier, convenient, and cost-effective for the user. Peer Ledger ensures identity by creating a credential-mapping solution that uses both a non-blockchain PKI and blockchain. These mapping and auxiliary services enable us to create interoperable credentialing and digital signatures among blockchain and non-blockchain applications.
