Short Description

Paladin is a platform for building privacy preserving tokens with infinite programmability on EVM.

This project hosts the entire code base for the Paladin implementation, which contains the following functionalities:

Privacy preserving token smart contract samples
- using Zero Knowledge Proofs, like zeto
- using the Notary certificates (included in this project)
- using the multi-party flows with EVM private smart contracts (included in this project). This provides function similar to that provided by the Tessera project with additional interoperability and other enhancements
Sidecar runtime next to a Besu node
Secure channels of communication to other Paladins over which it can selectively disclose private data
High performance transaction manager that coordinates transaction assembly, submission and confirmation across Paladin runtimes
Enterprise grade key management integration
Development, configuration, and deployment pipeline for privacy preserving smart contracts

Paladin supports token implementations that obey these basic principles:

use the EVM base ledger as the source of truth for order and finality of transactions
transactions from different tokens involved in a higher level flow like DvP or PvP are atomically interoperable via the base EVM ledger
store states in the EVM base ledger in a securely masked format preserving:
- Confidentiality: the data is protected via cryptography, and selectively disclosed on a need to know basis
- Anonymity: the parties involved in a transaction, or set of transactions, cannot be determined without access to the confidential data
