Validator

A validator is a node in a proof-of-stake (PoS) blockchain network that is responsible for validating transactions and maintaining the integrity of the network. In a PoS blockchain, validators are chosen to create new blocks and validate transactions based on the amount of stake, or the number of tokens, they hold.

Validators in a PoS blockchain are incentivized to maintain the integrity of the network by earning rewards for creating new blocks and verifying transactions. These rewards come in the form of newly minted tokens, transaction fees, or a combination of both.

Validators are also responsible for reaching consensus on the state of the blockchain. In a PoS blockchain, this is done through a process called "staking". Staking is the process of locking up a certain amount of tokens as collateral in order to participate in the consensus process and earn rewards.

The process of validating transactions in a PoS blockchain is done through the use of "staking pools". These pools are groups of validators who pool their resources together to increase their chances of being chosen to validate transactions and create new blocks. By pooling resources, validators can earn more rewards and make the network more secure.

Overall, validators play a crucial role in maintaining the integrity of a PoS blockchain network. They are responsible for validating transactions, creating new blocks, and reaching consensus on the state of the blockchain. They are incentivized to do so through rewards and the process of staking, which helps to ensure that the network remains secure and decentralized.

It's important to note that the process of validation in PoS blockchain can be different from other consensus mechanism, for example in Proof of Work it's the miner who validate the transactions and creates new blocks, and the validation process is based on the computational power.

Requirements to Become a Good Blockchain Validator

• A significant amount of the native cryptocurrency of the network as collateral (staking)
• High-availability and high-performance hardware for running a node
• A reliable internet connection and network infrastructure
• A strong understanding of the network's consensus mechanism and governance structure
• Effective security practices to protect the staked assets and the node from potential attacks
• Active participation in the network's governance and decision-making processes
• The ability to troubleshoot and maintain the node
• A strong reputation and track-record of being a trustworthy and reliable validator within the community
• Compliance with any legal and regulatory requirements

How Much Can You Earn as a Validator?

Becoming a validator in a proof-of-stake (PoS) blockchain network can be a lucrative opportunity, but the potential earnings depend on several factors such as the network's size, the number of validators, and the reward system.

Validators earn rewards by creating new blocks and validating transactions on the network. The rewards earned by a validator are directly proportional to their stake, which is the number of tokens they hold and validate.

The size of the network also plays a crucial role in the potential earnings. A larger network with more transactions generates more rewards for validators. Besides, the number of validators on the network can affect the rewards. Fewer validators in a network can earn higher rewards as there is less competition in creating new blocks.

The reward structure of the network can also impact the amount earned by validators. Some networks have a fixed reward system, while others may have a variable reward structure that adjusts based on the number of validators and the network's size.

However, being a validator also involves a certain amount of risk since the value of the tokens used as collateral can fluctuate, and validators may be penalized for violating the network's rules or failing to maintain the network's integrity.

Overall, the potential earnings depend on several factors, making it impossible to predict a specific amount. Still, it can be a profitable venture if done correctly. Before becoming a validator, it's important to research and understand the network's reward structure, size, and number of validators.

The earnings can vary from a few hundred to tens of thousands of USD annually, depending on the network's size, the number of validators, and the reward structure.

Liquid Staking vs Locked staking

Liquid staking and locked staking are two different ways of holding and staking cryptocurrencies to participate in the validation process of a proof-of-stake (PoS) blockchain network. Liquid staking allows the holder to move or trade their staked assets at any time, while locked staking requires the assets to be locked up for a certain period of time before they can be moved or traded.

Liquid staking provides more flexibility, while locked staking offers greater security and a higher chance of being selected as a validator. The choice between the two ultimately depends on the holder's risk tolerance, investment horizon and the specific characteristics of the PoS network they are staking on.
