The Proof-of-Execution (PoE) protocol integrates a dual-layer approach where a reputation-based system selects a small group of trusted nodes that perform minimal computation to reach a consensus.

The selection is based on historical behavior and performance metrics stored on-chain, which encourages honest node operation to maintain a high reputation.

These selected nodes execute a lightweight computational process to validate transactions, drastically reducing energy consumption compared to traditional proof-of-work systems, while still safeguarding network integrity.

This solution reduces energy use by over 90% compared to traditional methods, aligning with sustainability goals without compromising security.

It also enhances network efficiency and lowers operational costs, providing a strong incentive for blockchain developers to transition to this protocol.

Technically, the development of such a protocol is feasible with current technology but requires significant innovation in reputation management and low-energy computation methods.

Business-wise, transitioning existing networks may face resistance, but the sustainability incentives and cost benefits provide strong arguments for adoption.

The competitive landscape is growing, yet few solutions offer similar efficiency and security balance.
