Proof of Authority (PoA) Consensus Node

PoA is a consensus mechanism that relies on a limited number of trusted validators, chosen based on their identity and reputation. This mechanism is particularly suited for private or permissioned blockchains. Key benefits include:

• High Performance: PoA systems process transactions faster, making them ideal for enterprise applications.
• Trust and Transparency: Validators are pre-vetted and held accountable, ensuring a reliable network.
• Low Latency: With fewer nodes involved in the consensus process, transaction finality is achieved quickly.

In the Land Bank Coin platform, PoA is used to enhance trust and speed in applications requiring regulatory compliance and precise control, such as property title transfers and milestone tokenization.

PoA provides fast, trusted operations for specific use cases like project milestone tracking and escrow services.
