Off-Chain Attack

Definition ∞ An off-chain attack is a security threat that targets systems or transactions occurring outside of the main blockchain network. These attacks can exploit vulnerabilities in layer-2 solutions, sidechains, or other off-chain protocols designed to enhance scalability or privacy. Successful off-chain attacks can lead to the loss of funds or data corruption without directly affecting the security of the underlying blockchain itself.
Context ∞ Off-chain attack vectors are a significant concern for the expansion of blockchain technology, particularly as more applications move transactions to secondary layers. Current discussions often highlight specific vulnerabilities found in payment channels or state channels, and their potential impact on user funds. Security researchers are continuously developing new methods to detect and prevent these attacks, ensuring the safety of off-chain operations.
