How Proof of Work is Different from Proof of Stake?

Do you know about Proof of Work (PoW) and Proof of Stake (PoS)? Well, when you talk about cryptocurrencies like Bitcoin or Ethereum, you might come across these terms. They are systems used to secure blockchain networks and confirm transactions.

But do you know what they actually mean, and how do they work? No? Don’t worry in this manual we will break down this in simple terms. Let’s get started!

Proof of Work (PoW): Scratch the Surface

Proof of Work is the protocol used by Bitcoin and some other cryptos. It confirms transactions and adds new blocks to the blockchain. Miners, which are individuals with high-powered computers, attempt to solve a hard puzzle.

The first individual to solve it can add a new block of transactions to the blockchain. In return, they get a reward in the form of cryptocurrency.

Pros and Cons of Proof of Work

On the one hand, Proof of Work is extremely secure, and it’s almost impossible to hack it. It is also completely decentralized. Simply put, anyone with a high-powered computer can join.

Apart from this, it uses a lot of electricity. Proof of Work also requires expensive hardware to be able to mine successfully. Furthermore, transactions can take longer and can have high fees.

Examples of PoW cryptos include Bitcoin (BTC), Litecoin (LTC), and others.

What is Proof of Stake (PoS)?

Proof of Stake is a new, energy-efficient system used by most modern-day cryptos. It is a lottery system. Instead of mining, individuals “stake” (lock up) their coins to be able to potentially validate new transactions.

The more you stake, the higher the chances of you getting selected.

Advantages and Disadvantages of Proof of Stake

The best thing about PoS is that it consumes very little energy, hence it is eco-friendly. It also enables cheaper and faster transactions. And you don’t require costly computers to join.

There are some disadvantages too. Wealthier users have a better opportunity at receiving rewards. Additionally, some PoS systems may not be as decentralized as PoW.

Examples of PoS cryptocurrencies are Ethereum (ETH) after 2022, Solana (SOL) and Cardano (ADA).

Point	Proof of Work (PoW)	Proof of Stake (PoS)
Validation Method	Mining (computational power)	Staking (holding coins)
Energy Usage	High (requires lots of electricity)	Low (eco-friendly)
Security	Very secure but expensive to maintain	Secure but risks centralization
Speed	Slower transactions	Faster transactions
Examples	Bitcoin, Litecoin	Ethereum (after Merge), Cardano

Can Proof of Stake cause centralization?

Yes, Proof of Stake can lead to centralization. In Proof of Stake, the more coins you possess, the greater your opportunity at validating the transactions and receiving rewards. This benefits wealthy users, as they receive more rewards and have more authority.

Also, most users pool and join a staking pool rather than staking individually. If a few large pools control the network, they can seize it. Some PoS systems also have a high minimum stake, which prevents little investors from participating. But, some PoS models attempt to prevent this. They enforce cheating penalties, random validator choice, and voting systems.

Though PoS is more energy-efficient than Proof of Work, it needs to address these problems to remain decentralized.

What is Delegated Proof of Stake (DPoS)?

Delegated Proof of Stake is an improved and quicker version. Rather than all users to validate the transactions, the coin holders vote for a few delegates who operate the network.

Delegated Proof of Stake has both pros and cons.

First, it is quicker to make transactions because few delegates sign off the blocks. It is also more energy-efficient than Proof of Stake and Proof of Work. Additionally, users can be in control because they can vote for delegates and oust bad ones.

But there are risks too. The largest issue is centralization risk because few delegates control most of the network. The second issue is voter apathy, where users don’t vote, and the same delegates get to stay in power.

EOS, TRON (TRX), and Steem are the popular examples of DPoS.

How To Earn From Proof of Stake?

To earn from Proof of Stake, you need to participate in the network by staking your coins.

Here’s how you can do it:

1. Choose a PoS Coin: Pick a cryptocurrency that uses PoS, such as Ethereum 2.0, Cardano, or Solana.
2. Set Up a Wallet: You’ll need a wallet that supports staking. Some wallets let you stake directly. Others, however, require you to use a staking platform.
3. Stake Your Coins: Lock your coins in the wallet or staking platform. The more coins you stake, the higher your chances of being selected as a validator and earn more rewards.
4. Earn Rewards: As a staker, you’ll earn rewards in the form of additional coins. These rewards are usually distributed regularly, based on the rules of the blockchain.
5. Delegate Your Stake (Optional): If you don’t want to run your own validator node, you can delegate your coins to a staking pool. The pool handles the validation, and you receive a share of the rewards.
6. Reinvest Your Earnings: Some platforms let you automatically reinvest your rewards. This helps grow your stake and compound your earnings over time.
