What is Authority Masternode (AM) (VeChain)?

Authority Masternodes (AMs) maintain network consensus and the security of the VeChainThor blockchain. AMs are responsible for block propagation on the platform and enable VeChainThor's Proof-of-Authority (PoA) consensus methodology. In order to host an AM, the user must hold 25 million VeChain tokens (VET) and go through a rigorous authentication process. AMs are the most powerful nodes in VeChain's nodal hierarchy, and are very limited in number.
