In this article we will discuss Proof of Authority (PoA), consensus with trusted validators. Read more!

Understanding Proof-of-Authority (PoA)

Proof-of-Authority (PoA) is an innovative consensus mechanism that uses trusted validators to regulate block production and drive network operations. This approach facilitates fast transactions via the Byzantine Fault Tolerance (BFT) algorithm, relying on identity as stake in the process.

Key Features of Proof-of-Authority (PoA)

Ideal for Closed Networks

PoA is ideal for private companies or organizations looking to build a closed blockchain network, requiring no public participation.

No Mining

PoA networks do not involve traditional mining, but instead use nodes operated by trusted validators.

Emphasize Integrity Node

PoA prioritizes node integrity over activities that require large amounts of resources.

Reputation as a Bookmaker

Validators are incentivized to maintain network integrity because their reputation is directly tied to network performance.

Proof-of-Authority (PoA) Implementation Requirements

• Formal On-Chain Identification: Validators must be formally identified to ensure their legitimacy.
• Eligibility Criteria: Validators are selected based on criteria such as organizational affiliation or reputation.
• Procedure Compliance: Validators must comply with established protocols for block production and network validation.

Proof-of-Authority (PoA) Network Adaptability

• Adopt Public Blockchain Design Elements: PoA networks can adopt design elements and operational frameworks from public blockchains such as Ethereum or Cardano.
• Modified Operational Framework: Modifications are made to suit organizational needs.

Conclusion

Proof-of-Authority (PoA) offers an advanced consensus mechanism for enterprise-grade blockchain networks. With its emphasis on reputation-based validation and efficiency, PoA is attractive to organizations seeking a secure and scalable blockchain infrastructure.
