Overview of POSA Mechanism

The POSA consensus mechanism is designed to address efficiency and security issues in traditional blockchain consensus mechanisms. By combining the features of Proof of Stake (PoS) and Proof of Authority (PoA), it aims to create a blockchain environment that ensures decentralization while improving transaction processing speed and security.

Combination of PoS and PoA

In the POSA mechanism, the PoS (Proof of Stake) component is responsible for stake verification of nodes, ensuring that nodes with more tokens have a greater chance of participating in the block generation process. The PoA (Proof of Authority) component introduces an identity verification mechanism, allowing specific validating nodes to participate in the block validation process, thereby enhancing the network's resistance to malicious behavior.

Transaction Processing and Block Generation

Under the POSA mechanism, transaction processing and block generation become more efficient. By combining PoS and PoA, the POSA mechanism can quickly reach consensus while maintaining network decentralization and security. This enables DKPChain to handle a large number of transactions while maintaining low latency and high throughput.
