Understand Sybil Attacks and Countermeasures for Blockchain Networks

Sybil attack na hin threat wey dey important for blockchain networks wey person fit control di network through fake identities. Dis kind manipulation fit disturb consensus mechanisms and compromise di network integrity, wey fit lead to issues like 51% attacks and transaction censorship. Even though e bin identified for 2002, dis attack still dey relevant with some notable attacks on Ethereum Classic and Monero. Different blockchain systems dey use different consensus mechanisms, like proof-of-work and proof-of-stake, to counter Sybil attacks. Dis mechanisms, plus reputation systems and identity verification, dey try to increase di cost for attackers. Additionally, dem dey use Sybil filtering during token distribution and airdrops to prevent exploitation. Di evolution and resilience of blockchain security measures dey highlight di ongoing efforts to protect cryptocurrency networks from dis kind vulnerabilities.
