1. The absence of a centre: decentralised architecture (peer-to-peer)
Most online services operate like a central post office. Every message, every piece of data passes through a company's servers. This model, although simple, creates a single point of vulnerability: whoever controls the centre controls the data.
The new model removes this centre. It is inspired by the oldest form of communication: direct conversation. Applications built on this principle create peer-to-peer networks, where users' devices connect directly to each other.
The benefit for the user: there is no longer an intermediary that stores, analyses or can be compelled to hand over your exchanges. By removing the central server, we remove the possibility of mass surveillance at the source. It is the structural guarantee that nobody comes between you and your correspondent.
2. The shared secret: unconditional end-to-end encryption
In a secure architecture, encryption is not an option, it is a rule. Every piece of information, before it even leaves your device, is sealed in a cryptographic envelope. Only the final recipient holds the unique key that can open it.
This principle, known as end-to-end encryption, guarantees that even if some data were intercepted, it would remain a string of characters that nobody else could decipher.
The benefit for the user: this is a mathematical certainty. Your conversations, files and secrets stay private, out of reach of hackers, internet service providers and even the app's creators.
3. Sovereign identity: you are the key
Why should we tie our ability to communicate to a phone number, an email address or a social media profile? These identifiers anchor us in an ecosystem of surveillance and marketing.
A privacy-respecting architecture separates identity from personal information. Your account is no longer an entry in a database but a unique cryptographic key that only you control, generated and stored on your device. This is the principle of sovereign identity: you own and manage your own digital identity.
The benefit for the user: real anonymity and protection against profiling. You can interact freely without every action being tied to your real identity. There is no longer a centralised user database to hack or exploit.
4. Where the data lives: your device, your fortress
The cloud is convenient, but it is just somebody else's computer. Storing our most intimate conversations there is like handing the keys to our private diary to a third party.
The local-first model reverses this logic. By default the data stays on your device, encrypted and under your control. If a backup is needed, it must be encrypted with a key that only you hold, which makes the data unreadable to the storage provider.
The benefit for the user: total sovereignty over your data. You no longer depend on the security, the policies or the longevity of a third-party company. Your personal archives truly belong to you.
5. Network dynamics: resilience and concealment of metadata
Rather than a rigid, centralised structure, the network is formed by the participants themselves, in an organic and dynamic way. Messages do not follow a monitored motorway but intelligent paths optimised across this decentralised mesh.
This approach not only makes the network extremely resilient (there is no head to cut off), but also protects metadata, in other words the information about who is talking to whom. By carrying messages in encrypted form through other participants, it becomes extremely difficult to map social relationships.
The benefit for the user: double protection. Not only is the content of your messages secret, but the context of your conversations, your social circles, is protected too, which prevents profiling and the analysis of your relationships.
