How Does Proof of Work Inherently Resist Sybil Attacks?
Proof of Work (PoW) inherently resists Sybil attacks by making it economically infeasible to create a large number of fake identities. In a PoW system, influence is proportional to computational power, not the number of identities.
To have a significant impact on the network, an attacker would need to control a significant amount of the network's hash rate, which is very expensive. This makes it difficult for an attacker to create a large number of fake nodes and gain disproportionate influence over the network.
Glossar
Sybil Attacks
Threat ⎊ Sybil Attacks describe the malicious creation and operation of numerous false identities (nodes or addresses) by a single attacker to gain disproportionate influence over a decentralized network's decision-making or validation processes.
Sybil Attack
Architecture ⎊ The Sybil attack, within cryptocurrency, options trading, and financial derivatives, exploits the inherent design vulnerabilities of distributed systems reliant on identity-based consensus.
Proof of Work
Challenge ⎊ The core of Proof of Work (PoW) lies in computationally intensive puzzles designed to validate transactions and secure a blockchain network.
