How Does sUSD Work?

Decentralized Control

sUSD operates on the Ethereum blockchain, leveraging its decentralized network of nodes. This structure eliminates the need for central bank or government control, providing users with greater autonomy and enhancing network resilience.

Blockchain Core

sUSD utilizes Ethereum's blockchain, 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.

• Public keys (similar to account numbers) are used to verify ownership

This mechanism ensures fund security while maintaining pseudonymity for transactions. Additionally, sUSD's value is pegged to the US dollar, providing stability in the volatile cryptocurrency market.
