Detailed Guide on Delegated Proof-of-Stake (DPoS)

The Rise of a DPoS Consensus Mechanism

While blockchain is a relatively new concept, its emergence has its origin in past events. Thinking about the internet could make a person argue that ARPANET, unveiled in 1969, was the first iteration.

The technology underwent several changes. For example, new protocols such as the Internet Protocol and Transmission Control Protocol were unveiled.

More than two decades elapsed before the technology matured into the World Wide Web satisfactorily. One can consider blockchain technology as one that is still maturing.

An element that developers cannot seem to agree on concerns transactions’ confirmation on the blockchain. Bitcoin unveiled proof-of-work (PoW) as the initial consensus-based mechanism which miners encode transaction information in a format meeting a hash length requirement.

In 2012, Peercoin unveiled proof-of-stake (PoS), where the competitive element was eliminated, and network picked validators to mine new blocks. Nevertheless, PoS still experienced scalability, centralization, and security problems.  

The issues resulted in delegated proof-of-stake’s (DPoS’s) unveiling in 2014. This consensus mechanism is meant to address PoS’s and PoW’s shortcomings.

Definition of DPoS

In PoS systems, one validator is selected to generate a block based on a pseudorandom selection process. This is different from needing several miners to use significant amounts of energy over a lengthy period on proof-of-work systems.

To show dedication to the network, validators lock up a stake they stand to lose in case they take part in malicious activity. The problem comes with the idea of ‘pseudo-randomness.’

Traditional PoS networks must have an incentive to lock up a higher stake. Hence, those with higher stakes are picked more compared to those with lower stakes, causing an unwanted level of centralization.

DPoS addresses this issue. Rather than all stakeholders directly validating transactions, they vote for delegates to do the job. 

DPoS’s story started ten years ago with Daniel Larimer and the BitShares blockchain’s unveiling. Larimer’s creation introduced a new scalability and efficacy level to the blockchain world.

How DPoS Works

Voters 

These are entities or individuals that own tokens within the DPoS network. Their primary task is to take part in the network’s governance by voting for delegates. 

Tokenholders can either vote directly or delegate voting power to other representatives. Their vote’s weight is proportional to the number of tokens they hold. 

Voting in DPoS is a continuing process and tokenholders can change their vote anytime. Further, a majority of DPoS systems run a reward-sharing mechanism where some of the delegates’ rewards are distributed to voters who backed them.

Delegates 

These elected representatives are selected by tokenholders to validate transactions and generate new blocks. The delegates’ number ranges from 21 to 101.

Every delegate is tasked with generating and adding new blocks to the blockchain within a stipulated time frame. In case a delegate does not produce a block within the allocated time, the next delegate in line takes over, ensuring constant block production.

Benefits of DPoS

Examples of benefits offered include:

• Quick transaction times and high throughput
• Striking a unique balance between decentralization and practical centralization.
• Reduced energy use compared to PoW.
• Accountability among delegates that ensures a reliable and secure network.

Drawbacks of DPoS

Examples of disadvantages include:

• Centralization risks that increase the risk of collusion or single points of failure.
• The possibility of the voting process being significantly influenced by large stakeholders.
• Difficulty in ensuring delegate accountability.

How to Become a Non-delegate

Using the Tron network as an example, the factors to consider include:

• Ensuring a strong server setup with high security and reliability. One should have stable, high-speed internet and adequate computational power.
• Staking a significant amount of TRX tokens to show commitment.
• Submitting a candidacy proposal that highlights plans, intentions, and aims.
• Using forums, social media, and other platforms to campaign.
• Gathering votes.
• Maintaining performance as a super representative.

The Future of DPoS

Blockchain technology is still evolving. The most critical facets of change are the consensus mechanisms underpinning every blockchain since they represent the foundations, scalability, security, and decentralization of the network. It is critical to agree on the best-suited consensus mechanism for widespread adoption.
