dPOH: A Decentralized Proof of Humanity Protocol for Sybil-Resistant Blockchain Identity

Delegated Proof of History (dPoH) is a blockchain consensus architecture designed for the Kortana Blockchain. The protocol combines historical ordering, delegated validator governance, and Byzantine Fault Tolerant (BFT) finality to achieve secure, scalable, and deterministic transaction processing. dPoH introduces a historical participation model, validator reputation scoring, and delegated governance mechanisms that enhance security, decentralization, and network efficiency while maintaining resistance against common consensus-layer attacks.
