Storage

While the SDK integrators can utilize centralized storage, decentralized storage is the key to any modern Web3 solution.

There are four storage databases forming within the framework:

1. If we take a look at the dMail and dChat as an example, blockchain is used to store:

   • A link to the dMail JSON metadata, timestamp, checksum & sender address,

   • dChat encrypted message, timestamp & sender address.

2. The concept of decentralized storage is used for the temporary or permanent storage of encrypted communication and data files and JSON files (i.e. dMail, subject & content attachment location).

3. Integrators can also opt for more centralised storage such as cloud storage.

4. User local storage is used for storing:

   • wallet private keys,

   • dMail & dChat content hash, and

   • user-initiated backup of conversations, data files and reports.
