In the world of cryptocurrencies like Bitcoin and Litecoin, it's all about decentralization and financial self-sovereignty. This means taking control of your wealth and saying goodbye to traditional financial intermediaries. One of the ways individuals engage with this transformative shift is by operating their own nodes in the cryptocurrency network.

Being a node operator isn't just about participating; it's also about contributing to the network's stability. Nodes come in different forms - full nodes that store the entire blockchain, and lightweight ones that focus on specific parts. Regardless of their type, all nodes play a part in upholding the decentralized spirit of cryptocurrencies.

Over the past few years, storing your Bitcoins has become a major cause of concern and with a lot of malware with Bitcoin stealing capabilities flooding the internet, this has become an even bigger cause of concern. Mt. Gox, which was one of the leading Bitcoin exchanges suspended its operations in February 2014, and it claimed that over 850,000 bitcoins were missing, which had a value of around  $450 million at that time. All of this conveys that there should be a much advanced level of security in the Bitcoin ecosystem.
