What is Proof of Authority?
Proof of Authority (PoA) is a consensus mechanism used in secure digital ledger networks where transactions and block creation are validated by approved accounts, known as validators. PoA is often employed in permissioned-based DLT networks where the identity of participants is known and trusted. This mechanism is considered more efficient and scalable than proof of work (PoW), as it relies on a limited number of validators rather than extensive computational work.
Proof of Authority is suitable for applications where transactions need to be processed quickly and in a trusted environment, such as in supply chain management, where ensuring the integrity and speed of transactions is critical.

Immutability
Immutability refers to the characteristic of data or records that cannot be altered or deleted after being recorded. This principle is a cornerstone in the realm of digital transactions, underpinning the reliability and security of data management systems.
Digital Twin
In supply chain management, digital twins can model and monitor supply chain operations, predict outcomes under various scenarios, and optimise performance.
Timber Traceability
Timber Traceability refers to the ability to track the origin and movement of timber and timber products through all stages of the supply chain, from the forest to the final consumer. This process involves documenting each step of the journey to ensure the legality and sustainability of the timber sourced.
