How Cartesi Works

Decentralized Control

Cartesi operates on a decentralized network of nodes distributed globally, independent of banks or government control. These nodes collaborate to verify transactions, ensuring system transparency and attack resistance, granting users greater autonomy and enhancing network resilience.

Blockchain Foundation

Cartesi's blockchain serves as a public, immutable digital ledger recording every transaction. Transactions are grouped into blocks, linked through cryptographic hashing to form a secure chain. Anyone can view the records, establishing trust without intermediaries. Cartesi's unique approach involves storing data temporarily on sidechains governed by Proof-of-Stake consensus, reducing the need for constant communication with the underlying blockchain while maintaining security.

Ensuring Fairness

Cartesi utilizes Proof-of-Stake (PoS) consensus to validate transactions and prevent fraudulent activities such as double-spending. Validators maintain network security through staking CTSI tokens and validating transactions, earning CTSI rewards in return. Its innovation includes enabling complex computations off-chain in Linux environments while maintaining on-chain security guarantees.

Secure Transactions

Cartesi employs public-private key cryptography 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 while maintaining pseudonymous transaction privacy. The platform's architecture allows developers to build complex dApps using familiar programming languages and tools, with computations verified through the Cartesi Machine emulator.
