Proof-Of-Stake versus Proof-Of-Work: What to Know

In the current state of the cryptocurrency market, a lot of people have a huge misunderstanding of two terms: “Proof-Of-Stake” and “Proof-Of-Work”. There is a lot of confusion surrounding these terms, and a lot of information is being spread around on both sides. The problem is that many people just don’t know what “Proof-of-Stake” means and what “Proof-of-Work” means. This blog post will explain the difference between “Proof-of-Stake” and “Proof-of-work” and why it is important to know the difference.  

Proof-of-stake (PoS) is a consensus method by which users can participate in the consensus protocol of a blockchain network. If the network does not have enough computing power to reach the global consensus, the nodes with a high stake will take part in the consensus. However, most blockchain networks support proof-of-work (PoW) consensus, the most basic consensus mechanism. Most of the blockchain networks don’t offer the consensus mechanism of proof-of-stake. This is because there are many advantages to proof-of-work over proof-of-stake.

The two most common types of cryptocurrency technologies currently in use are Proof-of-Work and Proof-of-Stake. The difference between them is that Proof-of-Work (PoW) is a decentralized consensus mechanism, where miners solve complex algorithms to validate transactions and prevent double-spending. On the other hand, Proof-of-Stake (PoS) is a decentralized consensus mechanism, where users with a certain amount of coins in their possession validate transactions and prevent double-spending. At the moment, Bitcoin and Ethereum are the two platforms that use Proof-of-Stake.

When it comes to powering a network, there are several types of consensus algorithms available. Proof-of-work protocols are the most prominent consensus algorithms in use today, but newer consensus protocols are beginning to gain ground. Proof-of-stake is one of the newer consensus algorithms that is gaining popularity. It is starting to be used to power cryptocurrencies since it can handle more transactions per second than proof-of-work.

Proof-Of-Stake or PoS has been touted as the next-gen solution to Bitcoin’s scalability problem. So, when Bitcoin Cash was created last year, it was thought that Bitcoin would move away from PoW. Well, when Bitcoin Cash launched its main net in November, Bitcoin was still in PoW. This means Bitcoin can still utilize PoW to create consensus. It’s not clear why Bitcoin works so well with PoW, but this is what Bitcoin Cash is up against.

The Proof-of-Work (PoW) consensus technology, also known as “Bitcoin”, has been chugging along for over a decade now. As the industry has learned, PoW is highly wasteful. Because of this, PoW creates an inherent risk of energy over-consumption due to the energy cost of mining the PoW network. PoS, on the other hand, runs on much less energy but uses the same computational resources. PoS proponents argue that PoS is more efficient since it can be easily distributed between computers, providing each computer with the resources it needs to contribute to the PoS network. Since PoS is a “fair” solution, it is used for online casinos and online poker sites. 

Why does the world need PoS? PoW was first created for currencies, generally for its efficiency, security, and speed. PoS was created to decentralize the network without having to rely on costly hardware by making it completely possible for everyone to be a part of it. PoS was not intended to replace PoW but to complement it. PoS is more secure, but PoW is more scalable at the same time.

The blockchain revolution has got everyone thinking about what is the best consensus algorithm to use to power the blockchain. Bitcoin and Ethereum use Proof-Of-Work (PoW) to secure their blockchains, and Bitcoin and Ethereum both use a block reward, which encourages miners to keep mining and keep the network secure.

The cryptocurrency market just took a hit, and a lot of people are wondering what happened. On the surface, it may look to be a simple fork. That is because the software update changes the way the network is secured for 51% of attacks. But it turns out, there is more to this update. In the Proof-of-Work world, miners provide a service to the network by verifying transactions.
