Origins and Development History

Birth Background

USDC was created by Centre consortium in 2018 to address the need for a transparent, regulated stablecoin in the cryptocurrency ecosystem.

It was born during the rise of blockchain technology and decentralized finance, aiming to provide a stable, compliant digital dollar for crypto markets.

USDC's launch brought new possibilities for traders, investors, and DeFi users seeking a reliable USD-pegged asset on the blockchain.

How Does USDC Work?

No Central Control

USDC operates on decentralized computer networks (nodes) worldwide, free from direct control by any single bank or government.

These nodes collaborate to validate transactions, ensuring system transparency and attack resistance, granting users greater autonomy and enhancing network resilience.

Blockchain Core

USDC's blockchain is a public, immutable digital ledger recording 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.

USDC leverages the underlying blockchain technologies of the networks it's deployed on, benefiting from their respective performance enhancements.

Ensuring Fairness

USDC utilizes the consensus mechanisms of its host blockchains (e.g., PoS for Ethereum) to validate transactions and prevent fraudulent activities like double-spending.

Participants maintain network security through activities specific to each blockchain, such as staking or running nodes.

Its innovation lies in maintaining a stable value while leveraging the security of multiple blockchain networks.

Secure Transactions

USDC 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, with transactions maintaining a pseudonymous nature.

Additional security features include regular audits and transparent reserves backing each USDC token.
