The is a web socket server that bridges connections between a mobile device and a web page to enable a secure authentication using private blockchain keys stored on the mobile device.
This is similar to how WalletConnect bridges between a mobile wallet and a web application for blockchain transactions, however Verida enables database storage connections. In the future, it may be possible to leverage WalletConnect with additional extensions to replace this infrastructure.
Verida is currently running a server for both Verida Banksia and Myrtle that is used by default by all applications.
To start your application, use npm run start
There is an example configuration file located in src/config/index.example.js. Copy this file to src/config/index.js.
You must update AUTH_URI to match the domain name / IP address of the server. You will also need to configure the Auth Client library to use this value as the serverUri. See
You must configure each application this server will support in the CONTEXTS section. You can specify a different private key per context. All data is encrypted and signed using the private key. This enables the data to be decrypted by the end user and in the future, will enable Application Contexts to be registered to specific keys, providing enhanced man-in-the-middle attack protection.
You must specify valid DID_CLIENT_CONFIG if you are registering a new Verida Account (DID) with the private key of a context. See
The configuration file allows you to provide the private key of a valid blockchain account that can sign messages relating to the login process.
There is a loginOrigin property that, if specified, will check the origin HTTP header from each socket request to ensure it’s coming from the expected domain. This ensures third-party websites can’t easily request valid authentication tokens. This also ensures third party websites can be prevented from using the resources of any auth server that is running.
Malicious third parties could obtain a token by spoofing the origin HTTP header and then presenting that to the user. However, this loginOrigin property is passed inside the encrypted payload to the Verida Wallet and is displayed to the user. This allows the user to visually verify the domain name they are currently on matches the domain name displayed on the Verida Wallet login screen. In the future, the Verida Trust Framework will add an additional layer of security by matching on chain metadata against the public key and domain name used to sign the payload.
