Shielding

Privacy on Common is powered through the modular shielded pool framework, Shielder SDK. Here's a quick look at some of the highlights:

Shielded Pools

Common's privacy is ensured by shielded pools, a feature allowing users to deposit and withdraw assets, including ERC20 equivalents, in a non-transparency-assurance way. Inside the pools, user identities are cloaked with advanced cryptographic techniques.

Shielded Transfers

The shielded pool is private and secure with regards to on-chain transfers of assets. The system considers a settlement only when the recipient has claimed the transfer - eliminating most problems and losses arising due to incomplete transfers. Fraud Protection

Shielded pools are designed in a way that enhances compliance through the components below. Registrar: A trusted party or group responsible for registering new users by whitelisting their ZK-IDs. It adds an optional onboarding process.

Anonymity Revoker: Under extreme conditions, a trusted authority, or in some cases authorities, will deanonymize a given user if this is deemed necessary to achieve compliance with applicable regulations or rules.
