The idea is to create a canister per user and make the user the controller of their canister.
The main canister of the application would then orchestrate user canisters to implement the application’s functionality.
Since users are controllers of their canisters, they can install their own code, decide how to participate in the application, and determine what data to share.
These user benefits come at large development costs because the main canister needs to be programmed in such a way that it can handle all possible actions of potentially malicious user canisters.
Still without a package manager for creating such software easily, these user benefits come at large development costs because the main canister needs to be programmed in such a way that it can handle all possible actions of potentially malicious user canisters.

This is a new and unprecedented way of programming.
**There hasn’t been a successful implementation of this vision yet.**
A couple of projects that opted for this architecture, but only [NFID Vaults](https://nfidvaults.com) have given the ownership of canisters to the users.
A common misconception is that the canister-per-user architecture is the most scalable; actually, canister-per-subnet is more performant because it can utilize multiple subnets without having the overhead of too many canisters.
It is being implemented in [IC Pack package manager](https://docs.package-manager.com/) (the MVP is expected soon) - the software that allows to do canister-per-user architecture easily, making the user self-sovereig over their software.

One example is the [IC Pack package manager](https://docs.package-manager.com/) (MVP coming soon), which can be used to create a canister-per-user architecture.

A couple of projects that opted for this architecture by themselves (without using an universal package manager), but only [NFID Vaults](https://nfidvaults.com) have given the ownership of canisters to the users.
