Proof of Work Consensus

Proof of Work is a decentralized consensus mechanism requiring network participants to expend computational energy to validate transactions and secure the blockchain. It serves as the physical foundation for digital store of value assets, making it prohibitively expensive to attack or rewrite transaction history.

Miners compete to solve complex mathematical puzzles, and the first to succeed adds a new block to the chain. This process creates a verifiable link between digital activity and real-world energy expenditure.

It effectively prevents double-spending without the need for a trusted central intermediary. The security of the network is directly proportional to the total hash rate committed by miners.

In financial terms, this creates a cost-of-production floor that influences the market valuation of the asset. It is a critical component of protocol physics that ensures trustless settlement.
