Polkadot’s Network Security: Nominated Proof-of-Stake (NPoS)

To secure its network, Polkadot employs a unique consensus mechanism called Nominated Proof-of-Stake (NPoS). In NPoS, validators are responsible for confirming transactions from different parachains, while nominators back validators by staking their DOT tokens. This system ensures the network remains secure and resistant to attacks, while also fairly rewarding participants for their contributions.

Let’s delve deeper into the roles of validators and nominators, as well as other key players in Polkadot’s network security.

Validators and Nominators

Validators play a crucial role in securing the Polkadot network by staking their DOT tokens and verifying transactions on the Relay Chain. Nominators, on the other hand, are DOT holders who choose to support validators by delegating a portion of their DOT to them.

In return, nominators receive a share of the DOT earned by their chosen validator as staking rewards. This collaborative process of staking and validating ensures Polkadot’s network remains secure, while also fairly distributing rewards among its participants.

Collators and Fishermen

In addition to validators and nominators, Polkadot’s network security also relies on the roles of collators and fishermen. Collators are responsible for collecting data from parachains and submitting it to the relay chain, ensuring the proper functioning of the network.

Fishermen, on the other hand, act as watchdogs, monitoring the network for any malicious activity or invalid transactions. By working together, these diverse roles maintain the integrity and security of Polkadot’s ecosystem.

Polkadot’s Governance Model: Empowering Users

Polkadot is set to introduce a new on-chain governance model called Governorship version 2 (Gov2), which aims to reduce the concentration of voting power and replace the Technical Committee with the Polkadot Fellowship.

This innovative model will feature a voting system that allows anyone to submit proposals and have them approved by the community. By empowering users to have a say in the protocol’s future, Polkadot’s governance model fosters a truly decentralized and democratic decision-making process.

Voting Mechanisms

Polkadot’s Gov2 will incorporate various voting mechanisms that enable users to vote on proposed changes to the protocol, such as upgrades or new features. These mechanisms include referendums with the unique concept of Adaptive Quorum Biasing, which adjusts the required majority based on voter turnout, and batch approval voting, which allows voters to rank multiple proposals in order of preference.

By providing users with a variety of voting options, Polkadot ensures that its governance model remains fair, inclusive, and decentralized.

Polkadot Fellowship and Gov2

The Polkadot Fellowship will replace the Technical Committee in Gov2 and will be responsible for developing and maintaining the Polkadot protocol. Comprised of technical experts, the Fellowship will act as a self-governing body that represents the voice of the technical community, ensuring that the protocol’s development remains aligned with the needs and interests of its users.

By giving users a say in the protocol’s evolution, Polkadot’s Gov2 governance model fosters a more inclusive and democratic decision-making process.
