Delegated Proof of Stake (DPOS )
Delegated Proof of Stake is a consensus mechanism algorithm that was developed by a great developer who has developed many site's, he is also the developer of this platform steemit, and many other famous sites, he is name is"Daniel Larimer". Delegated Proof of Stake was developed to solve the problem of complex in communication that is a major setback in Proof of Stake (POS). DPOS can also be describe as a consensus mechanism algorithm which uses voting power of users. Steem is one of the cryptocurrency built using DPOS consensus mechanism algorithm.
The DPOS is more democratic than POS, representatives are selected from a pool to validate the block every 6hrs, which means that a representative that was selected to validate block 100 might not be among those selected to validate block 101, this ensures that it will be difficult to manipulate the network. In this algorithm, the users delegates their voting power (governing power) to the delegates who are selected from the pool in an election process and these users are rewarded for delegating their voting power by the representatives from their own rewards.
Proof of Stake (POS)
The Proof of Stake consensus mechanism algorithm is a consensus mechanism algorithm where validators are selected based on the total number of their stake, that is to say that users with higher stakes are selected as it's transactions validator, which are the people to govern the network. The Proof of Stake was a consensus mechanism algorithm that was developed to solve use of computing power in POW consensus mechanism algorithm. The POS give the governance power to only the rich people and this could be dangerous because they could use there wealth to manipulate the network to their favour. This algorithm don't consuming much energy in validating block transaction.
Comparing both Consensus Mechanisms
- In Delegated Proof of Stake consensus mechanism algorithm, there are few people that is governed and validate transaction on the network. While in PoS consensus mechanism algorithm, there are more people involved in governing and in transaction validation.
- Delegated Proof of Stake consensus mechanism algorithm was developed to enhance the activities of POS but POS consensus mechanism was developed for an improvement in Proof of Work (POW)
- Delegated Proof of Stake consensus mechanism algorithm is more energy efficient compared to Proof of Stake consensus mechanism
