# 4.2 – Proof-of-Stake Consensus

When confirming transactions over TRRUE Chain, the Network will reach consensus between Validators using a delegated Proof-of-Stake (**dPoS**) mechanism. Each Validator must first lock a fixed Validator Stake of \[TRRUE] in order to run the Validator Node and participate in the consensus to earn a reward.

In selecting a consensus mechanism for TRRUE Chain, the advantages of PoS over Proof-of-Work (**PoW**) and Proof-of-Authority (**PoA**) are significant.

Compared with other blockchain systems, dPoS offers a more suitable foundation for Trrue Chain, aligning seamlessly with the project’s environmental concerns, scalability requirements, and overall sustainability objectives. [13](../references)

Unlike PoW, which demands substantial computational power and electricity, PoS relies on validators who stake a portion of their tokens.

In PoW systems, scaling often involves complex and contentious protocol upgrades. PoS, on the other hand, facilitates seamless scalability by enabling higher transaction throughput as the network grows. TRRUE Chain, with its diverse ecosystem of projects and transactions, necessitates a mechanism that can adapt to increasing demands efficiently.

This economic disincentive makes PoS networks inherently secure.

Aside from the systematic benefits of PoS, the Consortium Members for the TRRUE Chain DLT can earn a variable yield from their Validator Stake and Node operations, resulting from three simultaneous earning opportunities:
