Stellar Consensus Protocol (SCP): Instant consensus for global payments! ⚡️⛓️
At the core of Stellar's speed and security is a unique consensus mechanism — Stellar Consensus Protocol (SCP). By July 2025, SCP provides:
High speed: Transactions are confirmed in 3-5 seconds.
Low costs: Extremely low transaction fees.
Energy efficiency: Does not require mining and large computational power, like Proof of Work.
Security and flexibility: SCP uses federated Byzantine agreement (FBA), allowing node networks to reach consensus without full centralization or complex Proof of Stake, while maintaining high security. This architecture makes Stellar ideal for large-scale and high-frequency payment operations.
