Ethereum Moving From Proof Of Work To Proof Of Stake
In the year to 2023, the global blockchain market is estimated to be worth $23.3 billion.
No wonder cryptocurrencies are slowly gaining popularity all over the world. Their decentralized nature, increased value, and availability strengthen their case. In fact, every three seconds a new article about Bitcoin appears on social networks, and its popularity is growing.
Some of the major cryptocurrencies traded globally include Bitcoin, Ethereum, and Tether. Ethereum is the biggest competitor to Bitcoin due to its widespread use of decentralized finance. By 2020, Ethereum recorded nearly one million transactions.
So when Ethereum announced that it was changing its consensus protocol, the entire crypto community took note and discussed what the future might look like. In this blog, we will talk about what this means and what is the future of crypto since this event occurred on September 15, 2022.
What is the consensus protocol?
Consensus protocols are algorithms that define the way companies use blockchain technology to access distribution agreements. More precisely, it is a protocol by which a single data value is applied across distributed systems to achieve the necessary consensus.
For cryptocurrencies, these protocols are called fault tolerance algorithms and are often called the basis of blockchain technology because they help verify transactions.
In the world of cryptocurrency, there are two main consensus protocols that matter - Proof of Work (PoW) and Proof of Stake (PoS). Let's look at it in detail:
Proof of Work (PoW)
Popular cryptocurrencies such as Bitcoin and Ethereum Classic use Proof of Work as a consensus protocol. In this protocol, miners competing to create new blocks in the blockchain network must go through several operations and find the hash token that matches the last block.
The process requires the miner to demonstrate great computing power and solve a mathematical puzzle. The winner gets back some Bitcoin or Ether by sharing the newly created block with the network. The protocol is considered secure because hackers require 51% of the computing power of the network. This means that the associated costs far outweigh the rewards.
Proof of Stake (PoS)
In PoS, the user with the highest stake can be given the role of authenticator. In this context, the authenticator is the observer of transactions. Therefore, the more a shareholder retains his share, the more likely he is to agree to it.
Proof of stake offers better energy efficiency, greater scalability, and lower hardware requirements, making cryptocurrencies more affordable. In addition, the validators are chosen randomly and not competitively. These advantages make PoS more future-proof than PoW - the main reason for the development of Ethereum.
What is the Ethereum exchange?
For contributors, this change means that instead of receiving block rewards for solving complex equations, they receive transaction fees. As rewards decrease, the reach bar will decrease. PoS speeds up processes in the ecosystem, enables users to complete transactions in real time, and improves user experience in dApps.
Most importantly, you can expect a significant reduction in gas fees as the Ethereum network seamlessly balances supply and demand.
Essentially, Ethereum's transition from PoW to PoS means the company is moving to a more energy-efficient option. Bitcoin currently has a large environmental footprint due to its popularity and proof-of-work mechanism.
However, by moving to PoS, Ethereum significantly reduces these environmental costs by removing complex crypto puzzles from the equation.
Furthermore, the Proof of Work protocol no longer appears to be possible because mining requires a large amount of processing power and excludes a large portion of the population from the computation. As a result, even the best Ethereum wallets will have to rethink their strategies going forward.
Although Ethereum has been trying to migrate to PoS since early 2020, it's more difficult than people think. One of the most obvious drawbacks of PoS is that it is inherently more vulnerable and less secure than PoS and facilitates phishing. Therefore, the application should solve these problems and be better used and resistant to attacks.
But don't think 51% of POS attacks are easy. Auditors who misbehave or are found to be complicit will lose their stake in the process, which is an essential security measure.
Among other things, Ethereum changed its network protocol to a proof-of-concept on September 15, 2022 with the recently introduced Beacon Chain, an algorithm for managing coordination within the network between the Ethereum Mainnet and the currently used token chains. .
Transition effect
The Ethereum community is deeply divided over the transition. One aspect focuses on security, predicting that POS will make crypto transactions more sensitive and secure.
The other side argues that Ethereum will be accessible to people who do not have a lot of computing power, increase speed and reduce the cost of payments, which is a strong case for the expansion of the cryptocurrency.
Currently, PoS adoption in the cryptocurrency world largely depends on the success of Ethereum's transition to staking. If the company can achieve its goals, the entire community will see that the consensus protocol can be useful. Additionally, this change allows more people to participate in the broader ecosystem.
Prior to the integration update in September 2022, Ethereum’s energy consumption last month (August 2022) was around 86 TWh per year. In principle, this can be compared with the average consumption of the country. After replacing interest with metal, this indicator decreased by 99.95% .
briefly
On September 15, 2022, Bitcoin's largest competitor and one of the most widely used cryptocurrency, Ethereum, announced that it would switch from PoW to PoS. While many debate the implications of this move, both sides have strong arguments.
Regardless of this argument, PoS has great potential to replace PoW, the widely used consensus protocol in the cryptocurrency market. For now, it remains to be seen how the Ethereum implementation will work and pave the way for cryptocurrencies in the future.
