There is a lot of confusion in the cryptocurrency-world about what Proof of Stake vs. Proof of Work really means, so we wanted to break it down for you:

The “proof of stake vs. proof of work reddit” is a question that has been asked on many occasions. The answer to the question is not always clear, but there are some common answers.

Proof of Stake vs. Proof of Work

Consensus is a catchphrase among blockchain enthusiasts, alongside decentralization and self-custody. If a cryptocurrency project is to flourish, it must be able to verify and record transactions without the involvement of a third party. Engineers devised a number of complex incentive schemes to address this issue. 

While each blockchain has its own approach to consensus, most protocols fall into one of two categories: 

  • Stakeholder proof (PoS)
  • Work evidence (PoW)

Understanding these consensus methods may provide investors with a better understanding of how their favored cryptocurrencies work. 


Proof of Stake vs. Proof of Work: What’s the Difference?

Although many crypto fans prefer PoS or PoW, each consensus method has its own set of characteristics. Understanding how these systems function may help investors in choose which coins they would feel comfortable utilizing. 


What Does “Proof of Stake” Mean?

Proof of stake is the newest kid on the block, but it’s quickly gaining popularity. 

This consensus technique, which was first suggested in the early 2010s, uses less energy than prior proof-of-work blockchains. Proof of stake networks, rather than forcing computers to solve math problems, invite individuals to participate in the validation process by depositing their tokens on the blockchain. 

People who opt to “lock” their currencies on a blockchain acquire the right to participate in transaction processing. This implies that everybody who invests tokens has a chance to create a new block and collect the lucrative token rewards! 

The more native tokens that individuals lock into a blockchain, the less there are floating about on the open market, and the more secure the network should be. Proof of stake is also regarded the “cleanest” consensus process since it does not need as much energy to build new blocks.

PoS systems are thought to be less vulnerable to a network assault and more scalable by lowering transaction times.


What Is Proof of Stake and How Does It Work?

Staking a cryptocurrency entails locking tokens on a project’s blockchain for a certain period of time. 

To become a validator node, each crypto project has its own requirements for how long and how much you must invest. You may transfer your cryptocurrency onto the native blockchain if you fulfill these prerequisites. 

You’ll help protect the network, steady the token’s price, and act as a validator node after you’ve placed your tokens on the blockchain. The proof of stake mechanism selects a “staker” from among the many to verify the next block. You will get token incentives as long as you perform your role as a validator. 

In general, the more tokens you stake on a blockchain, the more likely you are to have fresh blocks validated. Some Proof-of-Stake Cryptocurrencys, on the other hand, include randomized algorithms to make Distribution of Rewards more egalitarian. 

Consumption of energy 

Proof of stake networks have the advantage of being “greener” than proof of work systems. While proof of stake still needs processing power, it does not use as much energy as Bitcoin mining. 

Proof of stake networks, according to experts at the Ethereum Foundation, require 99.99 percent less energy than proof of work chains. 

Participation of Miners 

Proof of stake cryptos do not have “miners” in the traditional sense. Many proof-of-stake cryptos “pre-mine” their tokens before they are released. People on these PoS networks are staking pre-purchased coins rather than creating new ones. 

This technique, in comparison to proof of work blockchains, may make it simpler for common investors to participate in proof of stake blockchains. All that is required of investors is that they purchase their preferred token and accept to the network’s terms. 

The cost of becoming a validator node, on the other hand, is generally rather expensive. These constraints are intentionally made expensive in PoS networks to guarantee that validators have a lot of “skin in the game.” Furthermore, although validators stand to reap higher benefits, they also have larger duties. 

As a result, most small crypto investors “assign” their coins to a validator pool. The coin will be staked on your behalf by the validator you pick. In exchange, you will get a portion of the mining earnings that are paid out in interest. 

Validators on a PoS network may also be given the opportunity to vote on network improvements. If you delegate your tokens, the validator will usually vote on your behalf. 

It’s also worth mentioning that many proof-of-stake chains have validators assigned to them ahead of time. Big investors, partner firms, or official developers are often the pre-screened validators. While this frequently enhances the speed and scalability of a proof of stake currency, it may also raise the danger of centralization. 

Distribution of Rewards 

The protocol will award fresh blocks to validators in a proof of stake scheme. The more a person’s stake, the more likely they are to verify blocks and get staking rewards. 

However, many PoS chains use random functions to make it harder for large stakers to hog all the rewards. Some networks also reward people who’ve been staking for the longest time. The Distribution of Rewards will vary depending on which blockchain you’re using.

Security 

Some opponents contend that a proof of stake network is simpler to hack than a proof of work chain. 

To begin with, joining a proof of stake blockchain has a lower entrance barrier. To become a validator, you merely need to stake tokens, but proof-of-work miners must purchase and run costly machines. 

Furthermore, proof of stake networks may have a higher level of centralization. As previously stated, those that invest more tokens are generally rewarded more and have more voting rights. In addition, many proof of stake currencies store their data on centralized cloud services. 

Developers, on the other hand, are putting in place a slew of new mechanisms to prevent unscrupulous actors and boost decentralization. Many proof of stake networks, for example, will “slash” validators that publish fraudulent transaction data. Validators and delegators may lose all of their crypto in these situations. 

A few decentralized cloud storage firms also provide options for storing transaction data without depending on Big Tech. Projects like Arweave, for example, are assisting decentralized data storage on blockchains like Solana.  

While the security of proof of stake coins is a worry, a few novel approaches might improve their security in the future. 


Advantages of Proof of Stake 

  • Proof of employment is less environmentally friendly.
  • Transaction speeds are usually faster, and costs are usually cheaper. 
  • Because of the decentralized governance, it is easier to obtain an agreement on improvements. 
  • Tokens might be readily delegated for interest by average investors. 

The Drawbacks of Proof of Stake

  • Larger token holders frequently get more benefits and have more voting privileges. 
  • The entrance hurdle to being a validator is higher. 
  • For ledger storage, they are often dependent on third-party cloud providers. 
  • Even if the underlying token falls in value, compounded interest is taxed. 

Proof-of-Stake Cryptocurrency 

Despite the fact that proof-of-stake isn’t as ancient as proof-of-work, it looks to be the favored method among today’s crypto engineers. While proof-of-stake raises worries about centralization, more individuals are ready to accept that trade-off in exchange for increased efficiency. 

Here are a handful of the most popular cryptocurrencies that operate on a proof-of-stake system:

  • Solana: Founded by Raj Gokal and Anatoly Yakovenko, Solana is one of the crypto industry’s quickest smart contract platforms. 
  • Chainlink is an Ethereum-based project that has grown to become cryptocurrency’s biggest decentralized oracle. 
  • Cardano is a new smart contract platform that competes with Ethereum, similar to Solana. 
  • Polkadot: A smart contract “Ethereum killer” established by a former member of the Ethereum team, Polkadot is similar to Cardano. 
  • Polygon: Formerly known as Matic, Polygon makes communicating with the Ethereum main chain cheaper and quicker by using proof-of-stake. 

What Does “Proof of Work” Mean? 

Surprisingly, the concepts that underpin proof of work were first created to reduce the number of bothersome spam emails. However, the enigmatic Satoshi Nakamoto stated in 2008 that this consensus method may aid in the development of a decentralized digital currency. Bitcoin was created in an instant!

Proof of work is a method of confirming transactions on the blockchain by solving mathematical challenges. Every few minutes, computers on a proof of work network compete to answer this difficult issue. The winner of the mini-competition will have the chance to “mine” the next block and collect the token awards. 

Although environmentalists often object to proof of labor, there are advantages to this method.

Note from the Editor

At scale, PoW systems demand a lot of energy to execute transactions, but they are regarded more dependable.


What Is Proof of Work and How Does It Work? 

Proof of work is a technique for achieving competitive consensus. People who wish to join in a proof of work blockchain must provide their preferred coin some processing power. “Miners” get this energy in return for the opportunity to produce new blocks and win prizes. 

In the case of Bitcoin, a fresh test is run every 10 minutes or so. Bitcoin will be awarded to the machine that predicts the right number the quickest. This winner will also announce the most recent transaction on the Bitcoin network, which will be verified by other users. 

The complexity of these algorithms constantly grows as more computers join a proof of work network. This dynamic difficulty mechanism ensures that cryptos such as Bitcoin continue to churn out blocks at a regular 10-minute pace.

Consumption of energy 

People will have a higher chance of receiving those big mining payouts if they employ more processing power. However, as the hash rate on a blockchain rises, it gets more difficult to solve issues, necessitating even more computational power!

Environmentalists, as you would expect, aren’t fond of this incentive structure. Although miners should use renewable energy to decrease costs, it still takes more power than proof-of-stake networks. 

Bitcoin mining presently uses around 110 terawatt-hours per year, according to Harvard Business Review. That’s almost the same as Sweden’s average yearly energy use. 

On the other hand, there are a variety of creative solutions for miners to power their ASIC rigs using renewable energy. El Salvador, for example, is experimenting with using volcanic steam to mine Bitcoin. Companies like Intel are also working on new technology to make bitcoin mining more environmentally friendly. 

As research and technology into proof of work advances, unforeseen “green” technologies may emerge.

Participation of Miners 

Anyone with a laptop could theoretically start mining currency like Bitcoin. Back in the day, a normal computer might have made you quite a few Bitcoins. 

However, as the price of Bitcoin rose, so did the level of competition. Manufacturers began putting together powerful ASIC machines geared exclusively for mining. 

Mining popular PoW currencies like Bitcoin is now a large industry. Hundreds of thousands of rigs are used by publicly listed corporations and “mining farms” to address issues on several PoW networks. 

An “ordinary Joe” can only mine Bitcoin by purchasing ASIC equipment and joining a Bitcoin mining pool. Please keep in mind that the prizes in these pools are proportionate to the amount of energy you provide. 

Distribution of Rewards 

In a proof of work system, any computer might receive the block reward, but the most sophisticated units have the greatest chance. The amount that the successful miner receives is determined by the cryptocurrency’s pre-determined reward schedule.

Bitcoin, for example, halves its payouts after every 210,000 blocks (or about four years). The payout for a successful block was initially 50 Bitcoin, however it was reduced to 25 in 2013. The block reward has dropped to 6.25 Bitcoins by 2020. These payouts will continue to decrease until all 21 million Bitcoins have been mined. 

Some people are concerned about how to keep miners motivated without a block reward in this scenario. While transaction fees may still be earned by miners, they may not be sufficient to incentivize users to participate to the network. 

Security 

While a gang of bad actors may potentially overpower proof of work networks, doing so would be an expensive endeavor. Proof-of-work miners must spend a lot of money on energy and ASIC setups. Also, since proof of work networks don’t depend on the cloud for storage, it’s simpler to keep the blockchain free of nonsense.  

Furthermore, compared to proof of stake, proof of labor has a longer track record of achievement. 

While this does not rule out the possibility of criminals gaining control of PoW coins, it becomes less probable when the network expands to the scale of Bitcoin’s. 


Advantages of Proof of Work 

  • Decentralization and increased security 
  • Proof of work tokens with a fair launch generally have a more equal currency distribution. 
  • A successful track record over a prolonged period of time 
  • It’s possible that this may spur innovation in the renewable energy industry. 

The Drawbacks of Proof of Work 

  • a large amount of energy 
  • Fees are usually greater, and transaction times are slower. 
  • Scaling and achieving decentralized governance are more difficult. 
  • When incentives go, it’s unclear how to save evidence of labor.  

Coin with Proof of Work 

Although proof of work isn’t as glamorous as proof of stake, it remains the “foundation” of blockchain technology. Furthermore, since Bitcoin is based on proof of work, it’s doubtful that this consensus process will be phased out very soon. 

Here’s an intro to some of the most influential Coin with Proof of Works: 

  • Bitcoin: The world’s first and most valuable cryptocurrency, Bitcoin is often compared to “store of value” assets and dubbed “digital gold.” 
  • The Ethereum network, the world’s first smart contract blockchain, is powered by Ether coins. (Note: Ethereum is transitioning to a proof-of-stake system.) 
  • Litecoin: Developed by Charlie Lee, a former Google employee, Litecoin is a speedier and less expensive alternative of Bitcoin. 
  • Dogecoin: Invented by Elon Musk of Tesla, Dogecoin is a “meme” cryptocurrency that uses the same mining algorithm as Litecoin. 
  • Monero is a contentious cryptocurrency that prioritizes privacy and anonymity. 

Last Thoughts

It’s hard to determine if proof of stake is really a “improvement” over proof of effort. Hundreds of intense disputes are now raging over whether crypto consensus mechanism is the best.

Proof of stake and proof of work, on the other hand, are likely to remain the most popular consensus techniques. Developers are already looking at complex ways for improving these systems. As a crypto investor, knowing how your favorite projects validate transactions is critical for evaluating their security, scalability, and decentralization.

The “proof of stake coins” are a cryptocurrency that use the proof of work algorithm. In this system, the miners need to solve difficult mathematical problems in order to earn rewards.
