Definition ∞ Node identification refers to the process of uniquely recognizing individual participants, or nodes, within a decentralized network. This often involves cryptographic keys or network addresses that distinguish one node from another. Accurate identification is essential for maintaining network integrity and facilitating communication between peers.
Context ∞ News about blockchain security and network decentralization often discusses node identification as a critical aspect. Ensuring distinct identification helps prevent Sybil attacks, where a single malicious actor controls multiple identities. Advances in peer-to-peer networking protocols continually seek to enhance the robustness and reliability of node identification. This capability underpins the secure and transparent operation of distributed ledgers.
