Consensus Mechanism: Efficient QBFT Consensus

The EAD Chain uses the QBFT (QBFT Byzantine Fault Tolerance) consensus mechanism — a secure and energy-efficient protocol built for permissioned blockchain networks.

Unlike Proof of Work or Proof of Stake, QBFT relies on a set of trusted validators who work together to propose and finalize blocks through a voting process, ensuring consensus even in the presence of faulty or malicious nodes.

This provides:

• Fast finality, with blocks confirmed in seconds.

• High throughput, suitable for microtransactions and real-time educational services.

• Energy efficiency, with no mining or complex computations required.

In the context of online education, this ensures a reliable and stable blockchain environment where student data, credentials, and educational transactions are processed securely and rapidly.

EAD Chain is optimized to reach up to 100,000 transactions per second (TPS) with a block time of 5 seconds and an empty block interval of 60 seconds, ensuring the best performance with minimal energy consumption.
