What Is Proof-of-Work (PoW)?
It involves miners competing to solve complex mathematical puzzles to validate transactions and add blocks to the blockchain.
The first miner to solve the puzzle receives a reward in the form of cryptocurrency.
Safeguarding Blockchain Security and Decentralization
PoW is designed to ensure the security and decentralization of the blockchain.
Miners must dedicate computational power and energy to solve the mathematical puzzles associated with each block.
This computational effort makes it difficult for malicious actors to manipulate the blockchain.
This ensures the integrity of the blockchain and protects it from fraudulent activities.
PoW maintains the security and trustworthiness of the blockchain and its transactions by preventing double-spending and other forms of fraud.
Proof of Work vs. Proof of Stake
The main distinction between PoW and proof of stake (PoS) is how new blocks are created. In PoW, miners compete by solving puzzles, whereas in PoS, participants are chosen based on the cryptocurrency they hold.
Another difference is that PoW requires specialized hardware, while PoS does not.
PoW also consumes more energy than PoS as it relies on substantial computational power to solve puzzles.
