Proof of Work or POW is one of the initial methods for verifying crypto transactions.
When introducing cryptocurrencies, the main aim was to decentralize transactions, whereby financial organizations are left out of confirming these transactions. Proof of work was introduced to confirm transactions and maintain a decentralized form. Read on to find out what proof of work coins are, their difference with proof of stake tokens, some examples of POW tokens, POW token advantages, and disadvantages.
5 Best Proof of Work Coins and Tokens
This is the toplist with proof of work coins and tokens for people in United States. There may still be restrictions what people in the your geographic region are allowed to do when it comes to crypto. Cryptocurrencies are extremely volatile and not suitable for everyone to invest in. Never speculate with PoW tokens or any other type for that matter – with funds that you cannot afford to loose.

What is a proof of work token in crypto?
Proof of work is the first consensus system for verifying transactions and mining coins and tokens. Bitcoin first used it to rule out involving a third party to process transactions by a peer-peer transaction processing system. POW is a process that facilitates the addition of new transaction blocks to the crypto blockchain, whereby miners compete to earn the right to do so and win rewards. The more powerful and effective your computer is and the amount of energy you put into it, the better your chances of winning the mining rewards like POW coins and tokens.
How do proof of work tokens differ from proof of stake coins?
Proof of stake (PoS) and proof of work means staking vs mining. These are consensus systems designed to decide on transaction validators. With proof of work, you need quality hardware to verify transactions and mine new tokens and coins, which is expensive to acquire, but for PoS, you only have to stake your crypto as a reason to be given the right to validate the transactions. If you validate a bad block, some amount is deducted, but you are rewarded with coins and tokens if your operations are successful.
What are the top 5 POW coins and tokens?
Below is the list of the top 5 Proof of Work coins based on market cap in the beginning of February, 2022.
+Bitcoin (BTC), with a market cap of over $711 billion.
+Ethereum (ETH), having a market cap of over $ 322 billion.
+Cardano (ADA), with a market cap of over $ 34 billion.
+Solana (SOL), which has a market cap reaching $ 29 billion.
+Dogecoin (DOGE), reaching a market cap of $ 19 billion.
How does mining work in proof of stake?
In POS, you need to stake in some of your coins to be selected as a validator to verify transactions and mine new coins. If you stake a small amount, your chances of being selected as a validator are few; therefore, the more you stake, the better your chances are to win the right. Say, if your coins are 0.003% of the total amount stacked by potential validators, your odds stand at O.003% to be selected. Even though random validators are chosen, sometimes, there are other factors to be considered, like your experience length in staking their coins.
Why care about mining power for proof of work coins and tokens?
Suppose you want to become a miner; you need to know what’s in it for you: the rewards in newly mined crypto coins from solving the mathematical puzzles formulated by the algorithms of different crypto coins. When you understand the proof of work mechanism, you can also make a suitable judgment on which cryptocurrency to invest in based on its security in processing transactions.
The environmental impact of mining
While there are indeed claims that Bitcoin and other PoW coins use a huge amount of energy, some say its driven by people with a financial stake in the failure of crypto and decentralized finance. In essence, those with an ulterior motive to attack Bitcoin. However, there is a ‘green case for Bitcoin‘, for those with an open mind.
How come most newly developed cryptocurrencies use proof of stake instead?
Mining in proof of work means that you exchange energy and effort for cryptocurrencies, while in POS, you have to stake some crypto amount and let the system select you randomly depending on the stake amount. POS rules out high energy consumption and the need to have powerful hardware for mining. It also means transactions are verified quicker because you don’t need to solve mathematical puzzles like POW, which consumes time depending on how complex the problem is. Long-term holders of POS cryptocurrencies get better rewards and can also be picked over others to validate transactions.

Advantages of proof of work system
Some of the main positive factors about proof of work include, but are not limited to:
+This mechanism rewards miners with newly minted crypto coins.
+It offers a decentralized form of transaction validation.
+Neutral since it depends on computational power, not the staked amount.
Disadvantages of proof of work system
Some of the potential negative factors about proof of work include, but are not limited to:
+POW involves high energy usage that can amount to high bills.
+Mining can only be done effectively with expensive hardware.
+The transactions are slow because of processing.
+It includes costly transaction fees.
+POW machines need proper heat management to work well.
