Proof of Stake & Problem of PoS

[JOINNY]

Proof-of-stake is a cryptocurrency consensus mechanism for processing transactions and creating new blocks in a blockchain. A consensus mechanism is a method for validating entries into a distributed database and keeping the database secure. In the case of cryptocurrency, the database is called a blockchain—so the consensus mechanism secures the blockchain.

 

Storing all data on On-chain using the PoS method still ensures safety for the core values of blockchain technology but also limits the applicability of blockchain technology.

 

In fact, the system was designed to be decentralized, but the centralized power to pass consensus lies mainly in the Validator, which accounts for 2/3 of the energy through agreement. If the hacker-controlled consensus pass rate is above 67%, it will lead to an impersonated consensus, creating a black swan phenomenon.
