Hi! 👋

We’re pretty close to finalizing our encryption protocol:

> <https://github.com/enigmampc/EnigmaBlockchain/blob/master/docs/encryption-specs.md>

This^ document includes:

1. Bootstrapping the network
2. Registration of new nodes
3. Contracts state encryption
4. Contracts inputs and outputs encryption

Still not finished:

1. How network upgrades can occur without losing state and tx input/output history.
2. How to generate `contract_id` in a trusted way, to prevent two contracts having the same encryption key ([this section](https://github.com/enigmampc/EnigmaBlockchain/blob/master/docs/encryption-specs.md#contract_id)).

We’d love to get your feedback on this! 😊  
So please ask us hard questions, including about all of the “TODO reasoning” and about attack vectors.

All,

This is meaningful update to our earlier posts ([1](https://forum.scrt.network/t/network-key-management-agreement), [2](https://forum.scrt.network/t/input-output-state-encryption-decryption-protocol)). As expected, as we went deeper into the details there were quite a few small tweaks and changes to be made.

The general ideas are still the same. These are mostly finer implementation details but as spec goes - this is where people should look at.

Thanks @assafmo, @reuven, @toml and others for helping in finding solutions through our internal discussions. We welcome any outside feedback and issues that are raised.
