Proof-of-Work Security Model

Mechanism

Proof-of-work security models mandate that network participants expend computational energy to solve complex cryptographic puzzles, thereby establishing a high cost for verifying and appending new transactions to the ledger. This expenditure serves as a digital barrier to entry that prevents malicious actors from hijacking the consensus process without incurring prohibitive economic losses. By anchoring security in physical hardware requirements and electricity consumption, the architecture ensures that the cost of an attack significantly exceeds any potential gain from fraudulent activity.
