Proof of Work vs Proof of Stake: What is the Difference and which One is Better?

A few years ago, Bitcoin introduced the concept of mining to secure transactions. Mining through Proof-of-work (PoW) creates security for their blockchain and is considered one of the most important qualities in a cryptocurrency. But some argue this model will not be able to scale with demand, so alternative models are being developed that use different methods such as Proof-of-Stake (PoS).

In this article, I will compare the “proof of work vs proof of stake” and explain what each one is and how they are different. Then I will give my opinion on which one is better.

Proof of Work vs Proof of Stake: What is the Difference and which One is Better?

 

If you’ve been following the cryptocurrency market for the last year or more, you’ve most likely come across the phrase “Ethereum 2.0.” This is essentially an update that will enhance Ethereum by altering numerous components of the project and making it quicker, cheaper, more scalable, and more contemporary in a variety of ways.

Of course, one of the most significant changes for Ethereum users will be the transition from the Proof of Work consensus method to the more sophisticated Proof of Stake consensus mechanism. If you’re not sure what these methods are or why Ethereum is going to PoS, stay reading because we’ll explain everything.

What are Consensus Mechanisms, and how do they work?

We previously said that Ethereum intends to migrate from one consensus or mechanism to another, and in order to comprehend why this is important, you must first comprehend what these mechanisms are.

In essence, the cryptocurrency sector and crypto networks are decentralized, which means that no one entity controls all of the servers and all of the money on them. That also means there is no one to keep track of transactions, process them, and ensure that no one spends the same money twice or manipulates the funds in any other manner.

Banks, Visa, PayPal, and other centralized institutions achieve this in conventional banking, but we employ consensus processes in crypto. These are the technologies that enable the computers in a crypto network to agree on which transactions are valid and record them on the blockchain as true.

There are several consensus processes available these days, with each project establishing its own in order to stand out and change the market by introducing its idea of how transaction legitimacy should be established. The two most important ones, or the most important ones, are Proof of Work and Proof of Stake.

What is Proof of Work (PoW) and how does it work?

Proof of Work is the world’s oldest consensus mechanism. It was the first, created by Satoshi Nakamoto himself, to guarantee that Bitcoin transactions were verified, completed, and accurate.

Because the network takes a lot of computing power to operate the mechanism, process and validate transactions, assemble them into blocks, solve those blocks, and record them as part of the blockchain, it’s called proof of work.

Proof of Work networks now reward this effort by putting new currencies into circulation, and this is basically what crypto mining entails. These new coins are referred to be “mined,” and they are distributed to those who processed transactions as a reward for their contributions to the network.

So, what’s the issue, considering everything seems to be operating well here? Why did humans come up with new methods in the first place?

The reason for this is the amount of computing power required to operate the mechanism. It’s enormous, and it’s even considered wasteful. Despite its advantages, this mechanism is not only sluggish and difficult to scale, but it is also highly inefficient in terms of the electric power required to operate it, making it not very eco-friendly.

As a consequence, engineers opted to adopt an alternative method, resulting in Proof of Stake, a better consensus mechanism.

What is Proof of Stake (PoS) and how does it work?

As previously stated, Proof of Stake is the blockchain industry’s solution to the restricted and energy-inefficient PoW method. Staking, which is comparable to mining in PoW, is used in the new system to process the most recent batch of transactions, which are then grouped into blocks and subsequently put to the blockchain.

The procedure, like PoW, results in incentives for the participants, which are coins that have just been put into circulation.

Each PoS system is now somewhat different from the others, making it distinct. In general, every PoS blockchain employs a network of validators who pay cash rather than power to the project. They put their own cryptocurrencies on the line in exchange for the chance to validate transactions and be paid for it.

The network chooses the winner based on the quantity of coins given to the pool by each validator, as well as the length of time the coins spend there. Those that invest more crypto and maintain it in the staking pool for extended periods of time have the highest chance of earning significant rewards.

However, the procedure does not end there. Other validators are necessary to certify that the block is correct after the network picks the winner and validates the block. After that, the new block is added to the chain, the rewards are distributed, and the process begins again.

As a result, being a validator is a very essential position with a significant amount of responsibility. As a result, it needs extensive technical understanding as well as a large number of staked coins.

Why is Ethereum moving to Proof-of-Stake (PoS)?

Since its inception, the shortcomings in Proof of Work have been readily apparent. It’s scalability is restricted, it uses too much power, and it’s rather sluggish. In reality, it was evident that the mechanism would eventually need to be replaced with a better one. The issue was that there were no alternative choices back then, therefore Ethereum had no choice but to utilize PoW.

It is now paying the price, but it is also working on building and moving to its own PoS technology. Of course, several projects have long created their own versions of PoS, and many now utilize it as their primary solution. Because PoW is no longer appealing to anybody, developers must either switch to PoS or come up with a unique and altogether new approach.

However, most people prefer PoS because it is more scalable, has a lower carbon footprint, and uses less energy since it relies on stakers to contribute their coins rather than large amounts of computing power to solve difficult mathematical calculations.

Some of the most popular chains, like as Cardano and Tezos, already employ PoS, and Ethereum is on its approach to joining them. It is critical that ETH migrate to PoS as soon as possible in order to minimize its exorbitant transaction costs, which continue to rise owing to the lack of scalability of PoW, which is still in use on the Ethereum network.

Aside from that, PoS is just as secure as PoW, with significant economic penalties for any network interruption and a focus on deterring bad actors. Miners in PoW risk getting in trouble if they submit fraudulent information or blocks, wasting the community’s power and time.

Validators’ staked coins, on the other hand, operate as an incentive for everyone to comply, since they risk losing their coins if there are network disruptions or efforts to harm the system. Finally, they choose different ways, but they accomplish the same goal. PoS is just more efficient at it, delivering greater outcomes with less resources, making it the preferable choice.

In Proof of Stake, the network is secured by validating transactions through a process called “staking”. In Proof of Work, the network is secured by consuming computational resources to solve difficult cryptographic puzzles. The difference between these two types of networks is that in Proof-of-Work, individuals or entities who have access to more computing power are able to mine blocks faster than other users.

Frequently Asked Questions

Why is proof of stake more efficient than proof of work?

A: Proof of work is more efficient because it takes less time to mine a block. If you want fast transaction times, proof of stake is the way to go!

Is proof of stake less secure than proof of work?

A: Proof of stake is not a consensus algorithm. It does have its own problems that are similar to proof of work, but it is more secure in the sense that there isnt an incentive for miners (or validators) to cheat.

Is POS better than PoW?

A: This is a complex topic that cannot be answered with one sentence.
