Low Power Terminal

Definition ∞ A low power terminal refers to any computing device with limited processing capabilities, memory, or battery life that can still securely interact with a blockchain network. Examples include mobile phones, smart sensors, or embedded systems. These devices are optimized for energy efficiency while performing essential cryptographic operations, such as verifying transaction proofs. Their design prioritizes minimal resource consumption for broad applicability.
Context ∞ Low power terminals are central to discussions about the widespread adoption of blockchain technology, especially in areas like the Internet of Things and mobile payments. News reports often highlight advancements in lightweight cryptographic protocols that enable these devices to participate in decentralized networks without compromising security. The ongoing relevance concerns expanding the reach of digital assets and decentralized applications to a greater variety of hardware.
