A mobile node refers to a device that can connect to a blockchain network while being capable of moving from one location to another. This typically includes smartphones or tablets that run specific applications to access and interact with the blockchain.Mobile nodes usually don’t store the entire blockchain on the device. Instead, they may use lightweight protocols to validate transactions and interact with full nodes over the internet. This approach allows users to perform transactions, check balances, and send or receive digital assets without needing extensive storage or processing power.The use of mobile nodes enhances user accessibility, making it easier for individuals to manage their assets on the go. It plays a crucial role in the broader adoption of blockchain technologies, enabling more people to engage with digital currencies through user-friendly applications. Security, however, remains a concern, as mobile devices can be more vulnerable to hacks and malware.
