Nominator

Medium Trading

Nominators are participants in a blockchain network who delegate their tokens to a validator in a Proof-of-Stake (PoS) consensus system. By doing so, nominators support the validator’s ability to create new blocks and validate transactions. In return, nominators earn a portion of the rewards generated from these activities.

What are Nominators?

A nominator is a participant in a blockchain network who supports validators by staking their tokens. In PoS-based systems, validators are responsible for creating new blocks and confirming transactions. Nominators, on the other hand, do not create blocks themselves but delegate their tokens to validators, thus endorsing their performance and reliability.

What are the Roles of Nominators in a Blockchain?

Nominators are used in blockchain protocols for the following purposes:

  1. Delegation: Nominators delegate their tokens to chosen validators, effectively vouching for their honesty and competency. This delegation helps validators increase their staking power, which is essential for participating in block validation and network consensus.
  2. Rewards and Risks: In return for their support, nominators typically earn a share of the rewards generated from block creation and transaction fees. However, they also bear some risk, as the performance of the validator affects their rewards. If a validator misbehaves or performs poorly, nominators may face penalties or reduced earnings.

What is the Significance of Nominators to a Blockchain Protocol?

Nominators improve network security and decentralization by distributing staking power across multiple validators. This mechanism promotes a more robust and resilient blockchain network, reducing the risk of centralization and improving overall network performance.

Conclusion

Nominators are essential in PoS and similar blockchain systems, providing critical support to validators and contributing to the network’s security and efficiency. By understanding their role, participants can make informed decisions about staking and network participation.
