We're using blockchain as an identity layer, so that people do not need a phone number to use secure messaging. The messages live on a decentralized network, with storage abstracted. Meaning, all of the messages themselves do not live onchain.

Crypto allows for protocols to be monetized in new ways that actually help with fundamnetal problems of existing protocols like SMTP. For example, we can have a bulk-sender fee structure for rate-limiting, so people can pay for more timely delivery. This helps mitigate spam and increases quality of messages sent.

Node operators share in the revenue, so it really is decentralized messaging and economics, in which anyone can participate and earn.
