Proof of Work

Proof of Work is a system used to secure and validate digital transactions, like cryptocurrency, by requiring participants to solve complex mathematical problems. These problems demand significant computational effort, making it costly and time-consuming to produce new verified transactions. This process prevents fraud and double-spending because altering any information would require redoing the work, which is practically impossible at scale. In essence, Proof of Work ensures trust and security in decentralized networks by linking the effort of solving puzzles to the validation of data, encouraging honesty and maintaining the integrity of the system.
