Privacy considerations and techniques in blockchain – Blockchain Security and Privacy – Blockchain technology

Shanley0 CommentsTECHNOLOGYBlockchain, Technology

Blockchain technology offers unique security and privacy considerations. While blockchains are often touted as secure and transparent, privacy can be a challenge due to the inherent nature of a decentralized and immutable ledger. Here are some key privacy considerations and techniques in blockchain: Pseudonymity: Blockchain users are typically represented by pseudonyms rather than real identities. This offers a certain level of privacy by obfuscating the real-world identities of participants. However, transactions on the blockchain are still traceable and can be analyzed to infer patterns and potentially link transactions to real identities. Confidentiality: Confidentiality refers to the protection of sensitive information…

Blockchain security challenges and vulnerabilities – Blockchain Security and Privacy – Blockchain technology

Shanley0 CommentsTECHNOLOGYBlockchain, Technology

While blockchain technology offers various security benefits, it also presents its own set of challenges and vulnerabilities. Here are some key security challenges associated with blockchain technology: 51% Attack: In a blockchain network, a 51% attack occurs when a single entity or group gains control of more than 50% of the network's computing power. This control allows them to manipulate the blockchain, potentially leading to double-spending or unauthorized modifications of transaction history. Sybil Attacks: Sybil attacks involve an attacker creating multiple fake identities or nodes in a blockchain network to gain control or influence over the consensus mechanism. This can…
