Web 1.0

- All data processing happens inside organizational infrastructure;

- Web servers dynamically build results into web pages;

- Web pages transmitted as HTML to browser on use device;

- Browser on user device rendering the web page for the user.


- User session subject to attack and capture;

- Web server and database are bottlenecks for scalability;

- Database with all user data must be connected to the internet;

- Web servers and databases provide a large attack surface, making capture of the whole database possible.

Web 2.0

- Computation split between server backend and dynamic / HTML5 frontend;

- HTML5 application deployed to user from web server via HTTP;

- HTML5 application executed on user device;

-Connection maintained between local application and web servers to provide data to application on user device.

Benefits over Web 1.0

- Execution on user device allows for data richer applications with better user experience;

- Web server capacity issues are mitigated somewhat;


- Application can be compromised during deployment;

- User session subject to attack and capture; Web server and database are bottlenecks for scalability;

- Data base with all user data must be connected to the internet;

- Web server and data base provide large attack surface, and capture of whole data base possible.

Vereign SEAL

- All execution taking place on user device;

- HTML5 application deployed as decentralised App (dApp) via IPFS swarm;

- Data for application provided via asynchronous cryptographic container and encrypted fragments via IPFS swarm;

- Authenticity and evidential value of all data secured via hashes on the blockchain.

Benefits over Web 1.0

- Asynchronous data deployment model makes for efficient resource usage at the most convenient time;

- No more web servers to scale;

- No more web servers to compromise;

- No more user database connected to the internet, eliminating many of the possible compliance issues;

- Application well protected against compromise;

- Data protected against compromise;

- Transmission model includes messenger and more;

- Ability to provide evidential value and guaranteed authenticity without trusted intermediary.


- User input to Organization still requires some kind of REST API to accept data.
