What is Proof of History, and Why Does Solana Need POH?

Proof of History is one of the core innovations in the Solana ecosystem, which differentiates it from other layer 1 blockchains. It can help you find answers to “What is the role of validator in the Solana network?” by exploring the mechanics of a new consensus mechanism. Proof of History focuses on using time for synchronizing nodes in a trustless network. 

The consensus mechanism leverages the SHA-256 algorithm to create a rhythmic clock in which blocks are created in the form of comparative metrics of time. You cannot predict the output of the algorithm as Proof of History requires passage of time to produce the output. The time delay helps the network prove safely that time has passed with the creation of every block.

Proof of Work consensus mechanism presented challenges with the use of energy expenditure as the metric of time in which transactions are included in a block. It leads to a slow procedure as it is difficult to ensure that different new valid blocks have not been produced at the same time. Therefore, Proof of Work is not suitable for the domain of trustless finance. On top of it, Proof of Stake has also proved inefficient for use in the DeFi sector. 

However, Proof of History has solved the problems with existing consensus mechanisms. Every Solana validator node could agree on the ordering of events that have happened in the past, rather than agreeing upon a single point in time for finalizing transactions. In such cases, you don’t have to measure blocks in memory space, and you can rely on periods, which allow breaking down a specific timespan into infinite combinations. The staking protocol with Proof of History introduces a security layer for the network that would reward the positive contributors and punish the malicious agents.

Definition of Validators in Solana 

You can learn more about the impact of validators in Solana by exploring their definition. Validators are computer nodes that can help in running the Solana blockchain network. Every validator is responsible for executing a program that maintains track of all the accounts in the Solana cluster. It also works on validation of transactions before adding them to the network. The Solana ecosystem could not work without validators. 

Independent entities must run validators as more independent validators could ensure lesser vulnerability of the cluster to an attack that influences the cluster. As a validator, you can contribute to the growth of the Solana network. In addition, you can also develop a first-hand impression of the functionality of Solana clusters at the lowest level. Most important of all, you would become an invaluable part of an active community of operators invested in the Solana ecosystem.

Important Things to Know for Understanding Validators in Solana 

The important things you must know to understand validators role in Solana include the difference between consensus and RPC, Proof of Stake, Proof of Work, and Proof of History. You have already figured out the fundamentals of Proof of History in an earlier part of this post. The distinction between consensus and RPC could provide a detailed explanation for importance of validators. It is important to know that a validator software could offer the option of running a consensus node. You can also choose to run an RPC node as an alternative. 

The RPC node can help Solana developers and others interact with the blockchain. However, they could not vote due to concerns about performance. Therefore, the mention of a validator in Solana would point toward a voting or consensus node rather than an RPC node. Now, you should dive deeper into functioning of the Solana network to understand more about validators. 

  • Proof of Stake 

The Proof of Stake consensus mechanism is an integral element in the blockchain architecture that helps in powering up Solana. You can find answers to “What is the role of validator in the Solana network?” by reflecting on the working of Proof of Stake consensus. 

In the Proof of Stake consensus, token holders could stake their tokens with a validator. Upon staking their tokens, an individual would still have ownership of tokens and could remove the tokens from stake at any time. The staked tokens are a representation of the trust of token holders in the validator. 

When a person stakes their tokens with a validator, they receive rewards for their contribution to running and securing the network. You can gain more rewards by staking more tokens with validators. The Solana validator node with the highest amount of tokens in their stake would have a larger share of vote in the consensus mechanism. 

Therefore, validators get the opportunity to produce blocks in the network at a rate that is proportional to the size of their stake. Validators who are currently responsible for producing blocks in the network are known as the leaders. With the Proof of Stake consensus, Solana offers promising improvements over the Proof of Work consensus, such as reducing environmental impact. 

  • Proof of History       

Solana uses a combination of Proof of Stake and Proof of History to provide innovative advantages. Proof of History is one of the crucial innovations in the Solana ecosystem, which allows faster finalization of transactions. From a higher perspective, the impact of validators in Solana would point to their working mechanism. 

Validators in a cluster for Proof of History systems would have to reach an agreement on a cryptographically repeatable clock. The Proof of Stake and Proof of Work architectures are responsible for consensus in a blockchain network. The algorithms help in deciding which blocks you should add to the blockchain. 

On the contrary, Proof of History does not serve the functions of a consensus architecture. It is actually an innovative feature in Solana that ensures faster block finalization with Proof of Stake consensus architecture.

How Do Solana Validators Work?

The next important aspect in discussions about validators role in Solana ecosystem would point to their working mechanism. Validators would have to work on securing the network through generating and voting on blocks alongside improving decentralization through operations of an independent node. 

You would have to go over decisions for participating in discussions regarding changes on the network. In addition, you must also assume the responsibility for keeping your system running effectively and to ensure system security. Validators must also update their system with the latest software. 

With the growth in the number of tokens staked on your Solana validator node, you can reward the trust of people staking their tokens with you. How? You can run a reliable and high-performance validator node. In addition, you must have the necessary response mechanisms in place for responding to outages at different times of the day. Someone must be available at all times to review and fix the issues. 

Incentives for Consensus Validators and RPC Nodes

As you have learned, you can run a validator node as a voting/consensus node or an RPC node on Solana. Operators running a consensus validator node would have different incentives than the operators running an RPC node. Let us find out what you can gain from running consensus validator nodes. 

The primary focus of a validator node in Solana revolves around maintenance of the network and ensuring optimal performance of the node to ensure complete participation in the cluster consensus. You can understand the answers to “What is the role of validator in the Solana network?” by reflecting on the necessity of attracting a delegation of SOL to the validator. 

It would offer the validator node an opportunity to generate new blocks and earn rewards. All the staked validators earn inflation rewards from the vote credits. The validators who vote on blocks generated by the leaders receive vote credits. All validators who successfully vote on blocks added to the blockchain would receive vote credits. 

In addition, if the validator becomes the leader, it could also earn transaction fees alongside storage rent fees for every new block it generates and adds to the Solana blockchain. All the voting in Solana happens on the blockchain, thereby implying the need for transaction costs for each new vote. Therefore, every validator must have an adequate amount of SOL tokens in their identity account to make payment for the voting transactions. 

The outline of Solana validator requirements would be incomplete without understanding the economics of running consensus validators. You should know about the ways in which consensus validators could spend and earn SOL tokens through the protocol. All the validators voting on transactions should pay the vote transaction fees for blocks. Voting validators could earn SOL tokens through two distinct methods, such as inflationary rewards and 50% of the transaction fees for blocks generated by the validator.
