Origin and Development History

Background of Creation

Polkadex was created in 2021 to address the limitations of existing decentralized exchanges, which often suffered from poor user experience and limited liquidity. It was born during the DeFi boom, aiming to provide a decentralized trading platform that could rival centralized exchanges in terms of user experience and functionality.

The launch of Polkadex brought new possibilities for traders seeking decentralized yet efficient trading solutions.

Important Milestones

  • 2021: Mainnet launch, implementing the order book model for decentralized trading.
  • 2021: Introduction of the Fluid Staking Protocol (FSP), a key feature of the platform.
  • 2025: Continued development and optimization of the platform, with a focus on enhancing liquidity and user experience.

With support from its community and development team, Polkadex continues to improve its technology, security, and real-world applications in the decentralized trading space.

How Does Polkadex Work?

No Central Control

Polkadex operates on a decentralized network of computers (nodes) spread across the globe, 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

Polkadex'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.

As a Substrate-based blockchain, Polkadex benefits from the scalability and interoperability features inherent to the Polkadot ecosystem.

Ensuring Fairness

Polkadex uses a Nominated Proof-of-Stake (NPoS) consensus mechanism to validate transactions and prevent fraudulent activities like double-spending. Validators maintain network security by staking PDEX tokens and validating transactions, receiving rewards in return.

Its innovative Fluid Staking Protocol (FSP) allows for more efficient use of staked tokens, enhancing liquidity in the ecosystem.

Secure Transactions

Polkadex employs public-private key cryptography to secure 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 a level of pseudonymity for transactions. Additional security features include the platform's focus on compliance and regulatory standards to enhance user protection.
