What Is Proof of Stake? (Everything You Need to Know)
Proof of stake is a newer form of mining that many cryptocurrencies are starting to adopt. Instead of using large amounts of power to verify transactions, proof of stake simply requires you to own coins to participate in the network.

What Is Proof of Stake?
Proof of stake is a type of consensus algorithm that is used by some cryptocurrencies. Under this system, miners are not rewarded for verifying transactions. Instead, they are rewarded for holding coins in their wallets. The more coins you hold, the more likely you are to be chosen as a validator. When you are chosen as a validator, you can then validate transactions and earn rewards.
The proof of stake algorithm is designed to incentivize users to hold onto their coins instead of selling them. Doing so provides security for the network and prevents 51% of attacks from happening. 51% attacks are a major concern for proof of work cryptocurrencies. Although they require a great deal of computing power to carry out and centralizing this power is difficult, it is still possible.
By contrast, proof of stake makes it incredibly difficult to carry out a 51% attack. The more coins you own, the more you have to lose if the network is attacked. As a result, users are incentivized to keep their coins safe and secure. This provides increased security for the network as a whole.
Under proof of stake, there is no need for expensive mining equipment or large amounts of power. All you need is a digital wallet and some coins. This makes it much cheaper and easier to participate in a proof of stake network. Staking can be seen as a passive income source. You can earn rewards simply by holding coins in your wallet and keeping the network secure.
There are a few different ways to earn rewards under a proof of stake system. The first is through transaction fees. When you validate a transaction, you earn a small fee for doing so. The second is through block rewards. Block rewards are given to the validator when a new block is added to the blockchain. These rewards are usually a fixed amount of coins.
By staking your crypto, you are securing the network because it serves as an incentive for good behavior. The risk of staking is that if you act maliciously, you could lose your staked coins. Therefore malicious attacks would be counterproductive because it would mean losing your investment.
Coins That Use Proof of Stake (PoS)
Here is a list of the top coins that are currently using a Proof of Stake consensus algorithm:
If Ethereum’s change to PoS is successful, it will become the largest network using this consensus algorithm. Each team that developed these projects will have its unique reasons for using Proof-of-Stake but it’s clear that this consensus algorithm is on the rise. Let’s explore why that might be through the advantages that this system has to offer.
Pros of Proof of Stake (PoS)
The most obvious benefit of PoS is that it requires far less energy than PoW. With PoW, miners must expend large amounts of electricity to verify transactions and add blocks to the blockchain. This not only results in high energy costs but also contributes significantly to environmental pollution.
With PoS, on the other hand, there is no mining process and thus no need for expensive and energy-intensive hardware. This makes PoS much more environmentally friendly than PoW.
Another advantage of PoS is that it’s easier for users to participate in the network. To mine Bitcoin, for example, users must have access to expensive and powerful mining hardware. With PoS, users can simply stake their coins and start earning rewards.
The final advantage of PoS is that it is faster and cheaper than PoW. With PoW, miners must verify each transaction and then add the block to the blockchain. This process can take a significant amount of time. Transactions are verified almost instantly and blocks are added to the blockchain much faster in PoS systems. This results in a faster and more efficient network overall.
By having scaling capabilities, PoS systems can also handle a large number of transactions without any issues. Smart contracts with flexible use cases can benefit from this transaction speed. This is the main reason why Ethereum is planning to move from PoW to PoS in the near future. As the smart-contract blockchain with the most use cases, Ethereum needs to be able to handle a large number of transactions quickly and efficiently.
Cons of Proof of Stake (PoS)
Rather than working for rewards, proof of stake rewards those that are already wealthy. This can be seen as a major flaw of the system. Rather than creating decentralized economic opportunity, it instead entrenches the already rich and creates a smaller group of people that become very wealthy.
Another con is that it’s not as secure as proof of work. Because people can validate transactions without expending energy, it’s possible for someone with enough wealth to buy a majority of the coins and then validate fraudulent transactions. This could lead to double spending or other major problems.
Proof of stake also creates monetary value out of thin air, which could lead to inflation. Without proof of work via energy consumption, PoW maximalists believe that there is nothing to back the value of the coinage. Sound money isn’t possible with PoS if there’s nothing to back it.
Lastly, proof of stake can lead to centralization because the wealthier members of the community are more likely to have a larger stake in the system. This could lead to a concentration of power within the community, which goes against the decentralizing ethos of most cryptocurrencies.
Conclusion
The battle between PoS and PoW rages on but not that we answered the question, “What is proof of stake” it’s up to you to decide which system is better.
What is clear, however, is that PoS is on the rise and that it has a lot to offer in terms of efficiency, transaction speed, and environmental friendliness. Only time will tell if PoS can overcome its cons and become the dominant consensus algorithm in the cryptocurrency space.
