How Does sUSD Work?

Decentralized Control

sUSD operates on the Ethereum blockchain, leveraging its decentralized network of nodes worldwide. This removes the need for control by banks or governments, giving users greater autonomy and enhancing network resilience.

Blockchain Core

sUSD utilizes Ethereum's blockchain as 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.

Ensuring Fairness

As an ERC-20 token on Ethereum, sUSD inherits Ethereum's consensus mechanism. The stability of sUSD is maintained through the Synthetix protocol's mechanisms, including collateralization with SNX tokens and the foundation's market interventions when necessary.

Secure Transactions

sUSD employs public-private key encryption 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 transactions remain pseudonymous on the Ethereum blockchain.
