What is ZKJ: Understanding the Key Concepts and Applications of Zero-Knowledge Proofs

Polyhedra Network's Positioning and Significance

In 2024, the Polyhedra Network team introduced Polyhedra Network (ZKJ), aiming to solve interoperability challenges and scalability issues in the Web3 ecosystem.

As the pioneer of zkBridge technology, Polyhedra Network plays a crucial role in cross-chain communication and Zero-Knowledge (ZK) Proof applications.

As of 2025, Polyhedra Network has become a key player in blockchain interoperability, facilitating over 20 million cross-chain transactions across more than 25 Layer-1 and Layer-2 blockchains. This article will analyze its technical architecture, market performance, and future potential.

Origin and Development History

Background

Polyhedra Network was created by the Polyhedra Network team in 2024, aiming to address the lack of efficient and trustless cross-chain communication in the blockchain space.

It emerged during the rapid expansion of Layer-1 and Layer-2 solutions, with the goal of enabling seamless interoperability between various blockchain networks to enhance the overall Web3 ecosystem.

Polyhedra Network's launch brought new possibilities for developers and users seeking efficient cross-chain interactions.

Key Milestones

• 2024: Mainnet launch, achieving fast and secure cross-chain transactions using ZK technology.
• 2024: Introduction of zkBridge, revolutionizing blockchain interoperability without relying on third-party trust.
• 2025: Ecosystem expansion, supporting over 25 Layer-1 and Layer-2 blockchains.
• 2025: Milestone achievement of facilitating over 20 million cross-chain transactions.

With support from its community and development team, Polyhedra Network continues to optimize its technology, security, and real-world applications in the blockchain interoperability space.

How Does Polyhedra Network Work?

Decentralized Control

Polyhedra Network operates on a decentralized network of computers (nodes) worldwide, free from control by any single entity.

These nodes collaborate to validate transactions, ensuring system transparency and resistance to attacks, thus empowering users with greater autonomy and enhancing network resilience.

Blockchain Core

Polyhedra Network's blockchain is a public, immutable digital ledger that records every transaction.

Transactions are grouped into blocks and linked through cryptographic hashes, forming a secure chain.

Anyone can view the records, establishing trust without intermediaries.

Polyhedra Network's unique zkBridge technology further enhances performance and security in cross-chain communications.

Ensuring Fairness

Polyhedra Network employs a consensus mechanism to validate transactions and prevent fraudulent activities such as double-spending.

Participants maintain network security through various activities and are rewarded with ZKJ tokens.

Its innovation includes fast and secure cross-chain transactions using Zero-Knowledge Proofs.

Secure Transactions

Polyhedra Network uses public-private key encryption to protect transactions:

• Private keys (like secret passwords) are used to sign transactions
• Public keys (like account numbers) are used to verify ownership

This mechanism ensures fund security while maintaining transaction privacy.

Polyhedra Network's zkBridge technology adds an extra layer of security and efficiency to cross-chain transactions.
