'œYou've got to be honest and say how many problems is Bitcoin solving for you? It's adding problems man, it's making it harder for you but what do you get for your trouble? You get permission-less, unconfiscatable money' and that is valuable.''" Brian Lockhart Location: Skype Date: Monday, 26th August Project: Casa Role: Product Manager Full nodes are fundamental to the security of the Bitcoin network by maintaining decentralisation and validating transactions and blocks by enforcing consensus rules. While running a full node is an act of supporting the Bitcoin network, it also ensures that you are not trusting any third party. If a transaction breaks consensus rules, then your node will reject it, irrespective of what others nodes do. Further, running a full node offers increased privacy and safety. So why do so few Bitcoiners run a full node? Many either do not understand the benefits of running a full node and/or find it intimidating. While there are many useful online guides, most rely on at least some technical ability and not everyone has the inclination, hardware requirements or technical knowledge. The difficulties mean many, understandably, opt to use a hardware wallet, lite wallet and even trust exchanges or custodial wallets to secure their Bitcoin. It is hard to put a number on the number of nodes in operation, but certainly, the total amount is a long way off Luke Dashjr's target of 85% adoption. How can more users be encouraged to run a full node? Casa is one company trying to help by solving some of the friction points around education, design and user experience. Casa offers an out of the box, plug-and-play Bitcoin and Lightning node. In this interview, I sit down with Brian Lockhart from Casa to talk about Bitcoin full nodes. We discuss why it is vital to the individual and for the Bitcoin community, and how Casa is working to make it easier for people to run a full node.
