Nillion’s Unique Technologies

Multi-Party Computation (MPC)

Multi-Party Computation (MPC) is a cryptographic protocol that allows multiple parties to jointly compute a function over their inputs while keeping those inputs private. In Nillion, MPC ensures that data can be processed securely without revealing any sensitive information to the participating nodes. This technology is crucial for maintaining privacy and security in decentralized applications.

Fully Homomorphic Encryption (FHE)

Fully Homomorphic Encryption (FHE) enables computations to be performed on encrypted data without needing to decrypt it first. This means that data can remain encrypted throughout the entire processing cycle, significantly enhancing security. Nillion leverages FHE to ensure that data privacy is maintained even during complex computations, making it ideal for applications requiring high confidentiality levels.

Zero-Knowledge Proofs (ZKP)

Zero-knowledge proofs (ZKP) allow one party to prove to another that a statement is true without revealing additional information. In the context of Nillion, ZKP is used to verify transactions and computations without exposing the underlying data. This technology enhances trust and security within the network, allowing for verification without compromising privacy.

Nada Language

Nada is a domain-specific language (DSL) used within the Nillion Network for defining MPC programs. It facilitates secure and privacy-preserving computations on secret inputs from multiple parties.

How Nillion Works

Nillion Network Architecture

Nillion’s network architecture is designed to ensure secure and efficient data processing. It consists of three main layers:

• Processing Layer: This layer handles the computation tasks. It uses advanced cryptographic techniques to process data securely, ensuring that sensitive information remains protected throughout the computation process.
• Coordination Layer: The Coordination Layer manages the interaction between different nodes in the network. It ensures that tasks are distributed efficiently and that data flows smoothly between nodes, maintaining the network’s integrity and performance.
• Connectivity Layer: This layer is responsible for the network’s communication infrastructure. It connects the nodes and facilitates data exchange, ensuring the network remains robust and responsive.

Information-Theoretic Security

Nillion employs Information-Theoretic Security to protect data. This approach ensures that the security of the data does not rely on computational assumptions but on the inherent properties of the data itself. It provides a higher level of security, making it theoretically impossible for unauthorized parties to access the data, regardless of their computational power.

Role of Nodes and the Node Deployment Kit (NDK)

Nodes are the backbone of the Nillion network. They perform computations, store data, and facilitate communication within the network. Each node operates independently but collaborates with others to maintain the network’s overall functionality and security.

The Node Deployment Kit (NDK) is a set of tools and protocols that enable users to deploy and manage nodes on the Nillion network. It simplifies the process of setting up nodes, ensuring they are configured correctly and securely. The NDK also provides ongoing support for node maintenance, helping to keep the network stable and efficient.

Nillion’s MPC Protocol

Phase 1: Pre-Processing to Create Shares

In the first phase, Nillion’s MPC protocol prepares the network to handle high-value data securely. This involves generating and distributing shares (masks) for each factor and term in the sum of product expression using standard MPC techniques. The pre-processing phase is independent of input values and only depends on the number of inputs, ensuring that the appropriate number of shares are created ahead of computation.

Phase 2: Non-Interactive Computation on Masked Factors

The second phase involves the actual computation of private inputs, broken into three stages:

• Input Stage: Shares generated during pre-processing are distributed to parties. Each party combines their inputs with shares to create masked factors, which are then broadcasted to the network, maintaining information-theoretic security (ITS).
• Evaluation Stage: Parties perform local calculations on the masked factors, utilizing their computationally homomorphic properties to carry out operations like addition and multiplication directly on the masked data.
• Output Stage: Parties reveal the results of their local calculations. These results are aggregated to derive and output the final result of the multi-party computation.

Nillion Network

The Nillion Network is a secure computation network designed to decentralize trust for high-value data, similar to how blockchains decentralized transactions. It uses privacy-enhancing technologies (PETs) like secure multi-party computation (MPC) to perform blind computations over private data without revealing it to the network or other users.

Dual Network Architecture

The Nillion Network consists of two parallel, interdependent networks:

1.Coordination Layer (NilChain)
This layer acts like a manager, coordinating various activities across the network. It handles payments, governance, and resource management. It uses blockchain technology to maintain a shared global state, ensuring that all transactions and operations are properly recorded and managed. The Coordination Layer leverages blockchains for tasks like payments and governance, using the Cosmos SDK for a robust framework.

2.Orchestration Layer (Petnet)
This layer is where the magic of “Blind Computation” happens. It uses Privacy-Enhancing Technologies (PETs) like Multi-Party Computation (MPC), Fully Homomorphic Encryption (FHE), and Zero-Knowledge Proofs (ZKP) to perform computations on encrypted data without revealing the data itself. This allows for secure data processing while maintaining privacy. Unlike traditional networks, the Orchestration Layer does not rely on a global shared state or consensus on order. Instead, it focuses on decentralizing trust among nodes, allowing for secure computations over private data.

Live Testnet

The Nillion Network testnet consists of two interdependent testnet instances:

• NilChain Testnet: This testnet is live and allows users to create a wallet, use the testnet faucet, and send NIL testnet tokens.
• Petnet Testnet: Also live, it enables builders to connect their blind applications to the Petnet testnet, making them accessible to the community.

Local Devnet

For developers preferring to work locally, the Nillion SDK allows connection to a local instance of the nillion-devnet. This local devnet can be spun up using the nillion-devnet tool, allowing interaction with a local network while keeping the process running. Developers can later connect these applications to the Petnet testnet once they are ready.
