Other Frequently Asked Questions (FAQ)

Is there a fee for encryption/publishing and decryption/viewing digital content with VWBL?

Currently the VWBL protocol is free to use! See more details about how we're thinking about the future of VWBL.

What types of digital content VWBL SDK support?

The VWBL SDK supports any digital content, such as: images, music, text documents, etc. SDK's param of Preview type is File and digital content type is File/File[] so it is need to convert the loaded digital content into a File type

How do we upload large data?

Please compress and split large data into an array of File before inputting them into the SDK.

Is VWBL's code open source?

Yes! VWBL's Smart Contract and the VWBL SDK is open source. Later on, the VWBL Network will also be open source during phase 2.

What key is used for encryption and decryption?

VWBL SDK generates 128 bit symmetric keys. The key is divided to n of m keys with Shamir's Secret Sharing (SSS) and when n key fragments are collected, the original key is reconstructed by collecting n key fragments.

What encryption algorithm is VWBL using?

VWBL uses AES algorithm for symmetric encryption.

What is consensus algorithm of VWBL Network?

The consensus algorithm is DPoS. Nodes voted by delegators acts as validators and approve the block. In addition, validators manage key fragments.
