The attacker creates multiple pseudonymous identities to gain a disproportionately large influence on the network. In the context of The blockchain is a digital ledger that records transactions in a secure and decentralized manner. Think of it like a shared spreadsheet that is constantly..., a Sybil attack can disrupt the consensus mechanism, which is crucial for maintaining the integrity and security of the blockchain network.
In a Sybil attack, the attacker creates multiple false identities (nodes) in the network. These nodes can then be used to carry out various malicious activities, such as double-spending in a Cryptocurrency is a digital or virtual currency that uses cryptography for security and operates independently of a central bank. Cryptocurrencies use decentralized technology called blockchain... network or manipulating the consensus mechanism in a blockchain network. The attacker can also use these nodes to disrupt the network’s operations or to gain an unfair advantage, such as Crypto mining is the process of validating transactions and creating new units of cryptocurrency through solving complex cryptographic puzzles using computer hardware.
