In PoA, users need to disclose their identities to cross-reference other public data. Users who become validators are incentivized with rewards such as money or other benefits, which prevent them from engaging in malicious behavior. Verification plays a core role in creating trust, and  thus forms the foundation of the PoA protocol. Verification can be performed through the use of decentralized applications (DApps), which can be independent or carefully selected by projects that utilize strict verification processes."}]}],"pr":"fc02169c0a44182bfab472477cf493741e12200891e47c02911d58e911c226f0"}
