Blockchain is widely applied in logistics, finance, and agriculture. As single blockchain users grow, scalability becomes crucial. However, existing works lack a comprehensive summary of scalability. They focus on chains or cross-chain technologies. This survey summarizes across the physical logical layers, as well inner-chain, inter-chain, technology dimensions. The layer covers data protocols, while represents architecture. Each component analyzed from inner-chain inter-chain perspectives,...

Semiconductor devices are ubiquitous in modern life, essential to almost all electronic equipment. These devices, particularly diodes and transistors, crucial for amplifying controlling current voltage various components. Field-Effect Transistors (FETs), a type of transistor, control output through input categorized into Junction (JFETs) Metal-Oxide-Semiconductor (MOSFETs). JFETs operate under reverse bias function only with negative gate-source voltage, while MOSFETs further classified...
