ZK Dictionary

Zero knowledge technology: Allows one party to prove a statement is true without revealing any other information, ensuring privacy and security in transactions.

Zk proofs: Cryptographic proofs that show someone knows information without revealing it, maintaining privacy and security.

SNARK (Succinct Non-interactive Arguments of Knowledge): A small, quick-to-verify ZK proof that doesn't require back-and-forth communication.

SNARKtor: A protocol developed by Telos that aggregates multiple zk proofs into one, simplifying verification and reducing computational costs.

zk Proving FPGAs: Specialized hardware designed to generate zk proofs efficiently, offering the flexibility to adapt to various cryptographic algorithms and proof types.

Telos’ Objective Approach to zk Technology

Telos is creating a zkEVM L2 for Ethereum.

This involves leveraging both the SNARKtor protocol and zk proving FPGAs to overcome Ethereum's limitations.

SNARKtor protocol aggregates multiple zk proofs into one, and zk proving FPGAs is specialized hardware designed to generate zk proofs. This dual approach enhances the scalability and performance of blockchain operations.

Proof Aggregation Through SNARKtor

SNARKtor aggregates multiple SNARK proofs, packages them into a single proof, and sends it to the main chain. This process significantly enhances scaling benefits and efficiency, making it a pivotal part of Telos' zk strategy. By leveraging SNARKtor, Telos can process a larger number of transactions more efficiently, which is crucial for the widespread adoption of zk technology.

Hardware Acceleration Through zk Proving FPGAs

zk proving FPGAs (Field-Programmable Gate Arrays) are the hardware components specifically designed to generate zero-knowledge proofs. These specialized hardware units optimize the process of creating zk proofs, making it faster and more efficient compared to using general-purpose processors.

The Need for zk Proving Hardware

To illustrate the necessity of zk proving FPGAs, consider the analogy of a race. Using a Toyota Prius in a race might be efficient for daily use but isn’t optimized for performance. Similarly, zk proving FPGAs are designed for high efficiency and performance, crucial for zk technology.

Zero-knowledge proofs (zk) allow one party to prove to another that a statement is true without revealing any information beyond the validity of the statement. Telos' approach involves hardware-software co-design, which means designing both the hardware and software in tandem to optimize performance. Additionally, SNARKtor leverages recursive proofs, where a proof can be verified by another proof, making the entire process more efficient and scalable. This comprehensive strategy makes zk technology more accessible and efficient.
