Proof Of Stake In Blockchain Training Ppt

Slide 1

The purpose of this slide is to provide an overview of the PoS consensus mechanism used in the blockchain. It also includes information regarding the validators (forgers) and coins that use the proof-of-concept algorithm in the blockchain.

Slide 2

This slide illustrates the working of the PoS consensus algorithm in the blockchain, providing information regarding the selection of validators or forgers and approval voting for creating the new block.

Slide 3

The slide contains details related to major advantages offered by the proof of stake consensus which are higher energy efficiency, inexpensive, and faster transaction speed. It also includes information about the disadvantages of PoS, such as unproven security and the risk of oligopoly.

Instructor’s Notes:

The major benefits offered by the PoS consensus mechanism are as follows:

• Higher Energy Efficiency: PoS uses far less energy to complete a blockchain transaction as there are no complex mathematical computations to perform
• Inexpensive: PoS is relatively cheap as there is no need for skilled talent and specialized hardware and software to execute the PoS consensus mechanism in the blockchain
• Faster Transaction Speed: PoS guarantees more transactions per second – up to 100,000 compared to only 64 transactions per second in PoW

The major limitations of the PoS consensus mechanism are as follows:

• Unproven Security: PoS as a consensus mechanism is relatively new hence its security still remains unproven for long-term usage
• Risk of Oligopoly: Individuals with a greater stake in the blockchain network can hold more influence than individuals with smaller stakes

Slide 4

This slide tabulates the benefits and limitations of the PoS algorithm used in blockchain. The major advantages of the PoS consensus algorithm are high energy efficiency and faster transaction speed. The major disadvantages of the PoS consensus mechanism are unproven security and staking of coins for a stipulated time period.

Slide 5

This slide highlights the difference between the Proof of Stake and Proof of Stake on multiple parameters such as block creation probability, winner selection, reward, transaction speed, energy efficiency, cost and reliability.
