How Does Polkadex Work?

Decentralized Control

Polkadex operates on a decentralized network of computers (nodes) spread across the globe, free from the control of any single entity. These nodes collaborate to validate transactions, ensuring system transparency and resilience against attacks, thus empowering users with greater autonomy.

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.

Ensuring Fairness

Polkadex likely employs a consensus mechanism to validate transactions and prevent fraudulent activities such as double-spending. Participants in the network maintain security and receive PDEX rewards for their efforts. The platform's innovative Fluid Exchange Protocol (FSP) aims to enhance liquidity and trading efficiency.

Secure Transactions

Polkadex uses public-private key encryption technology to secure transactions:

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

This mechanism ensures fund security while maintaining a certain level of privacy for transactions.
