Why You Should Run a Bitcoin Node
What is a Bitcoin Node
A Bitcoin node, in super simple terms, is a computer that runs the Bitcoin software. This node holds a copy of the entire Bitcoin blockchain (timechain), the ledger that contains all the transactions ever made in Bitcoin. It follows the set rules of the Bitcoin network and can verify transactions, ensuring they follow these rules. By doing so, nodes help keep the Bitcoin network secure, validating the activity on the network.
1 Certainty:
Running a Bitcoin node provides you with certainty in your transactions is similar to testing gold when you buy it. Just as you would want to be certain of the purity and authenticity of your gold, running a node allows you to independently verify and confirm the authenticity of Bitcoin your transactions. This way you don't have to rely on someone else's word or trust that a third party service has done the verification correctly (Don't, trust Verify). This way you can personally ensure that what you're receiving is genuine, much like testing gold ensures that you're getting the real precious metal, not something counterfeit.
2 Voting:
Running a Bitcoin node gives you the ability to be an active "voter” on the network. By operating a node, you get to choose which version of the Bitcoin software you run. This choice reflects your support for specific rules or changes within the Bitcoin network. When there's a proposed change in the protocol or new features, node operators effectively "vote" by choosing to run software that supports these changes or by sticking to the existing version.
​
This was demonstrated with the creation of Bitcoin Cash (BCH), those who believed in the proposed change ( a larger block size) switched their nodes to run software compatible with the BCH rules, essentially voting for this change with their technical support. Conversely, those who remained with the original Bitcoin rules continued running their nodes happily on software that maintained the original block size limit, voting against the proposed change. Then everyone lived happily ever after, except the BCHer’s.
This process ensures decentralised governance, where changes are made based on the consensus of the network's participants or more specifically node runners, rather than being dictated by a central authority.
3 privacy:
When you don't run your own Bitcoin node you instead rely on someone else's node, this means you potentially compromise your privacy. This means your transaction information, including your Bitcoin addresses and the details of your transactions, can be visible to the operator of the node you're using. This is because you are depending on their node to broadcast your transactions and retrieve information from the blockchain.
Running your own node ensures that your transactions are directly communicated to the Bitcoin network, this reduces the exposure of your financial data to third parties. It's like having a direct line for your transactions, rather than going through someone else's node where your information could be observed.
Additionally, when you rely on someone else's node, they essentially have the ability to vote on your behalf if there is a change proposed to the Bitcoin network. Their node follows the rules and supports the version of the Bitcoin software that they choose, not you. This means that they have a say in the future direction of the Bitcoin network through their node, and your relying on their node indirectly supports their vote. Running your own node gives you back this control, allowing you to have a say in the network's decisions and safeguards your privacy.
4 strengthening the system:
Becoming a Bitcoin node runner contributes significantly to the strength and resilience and overall robustness of the Bitcoin network. Each node acts as an individual point in the network that validates transactions and blocks. The more nodes there are, the more distributed the network becomes, making it harder for any single point of failure to disrupt the system. To shut down Bitcoin, every single node would need to be individually located, turned off, or destroyed. This task would require an extraordinary amount of time, energy, and manpower and is, to say the least, unfeasible. As nodes could reappear faster than they could be shut down, it would result in a large-scale game of whack a mole.
This decentralisation is a core principle of Bitcoin. It ensures that no single entity has too much control or influence over the network. By becoming a node runner, you're participating in this decentralised model, maintaining the integrity and security of the entire system. The collective effort of thousands of nodes around the world ensures that Bitcoin remains a robust and reliable currency.
5 Become an "Uncle Jim":
An "Uncle Jim" in the Bitcoin community refers to someone who runs a node and accommodates friends, family and community members to connect to it.
Becoming a node runner means you can become an Uncle Jim! This not only helps your friends and family to transact with better privacy and security, but it also aids in onboarding them into the Bitcoin system. You’ll become a point of education and support, helping others understand and navigate the Bitcoin world. Additionally, assuming that you, your family, and friends all share similarly aligned values, they can more safely assume that you would make the right decisions when voting on proposed changes to the network, as opposed to trusting some unknown node user.
Sum-up:
Making the decision to become a node runner offers heaps of benefits, particularly for those who value individual freedom, responsibility, and sovereignty. It provides certainty allowing users to independently verify. It acts as a form of voting, giving node operators a say in the network's governance and future direction. Your privacy is enhanced, as using on your own node avoids sharing transaction details with third party node users. It strengthens the Bitcoin system, contributing to its decentralisation and resilience against failures or attacks. Lastly, becoming an 'Uncle Jim', giving you the ability to support friends and family in using Bitcoin securely. While it's not necessary for every Bitcoin user to run a node, doing so is highly recommended for those who value these principles.
Nodes
Some Bitcoin node solutions on the market include MyNode, Umbrel, and Start9. Each of these solutions offers a different experience, catering to various needs and technical expertise levels. Additionally, building a Bitcoin node using Raspberry Pi 4 components is a popular choice for those who prefer a more hands-on approach.
Umbrel: umbrel.com
another Bitcoin node known for its sleek user interface and simplicity, It's geared towards users who value ease of use and are perhaps newer to running nodes.
MyNode: mynodebtc.com
An it easy to run a dedicated Bitcoin node. It's designed for users who want a user friendly interface.
Start9: store.start9.com
Start9's Embassy product is a more privacy focused solution. It is a self hosted server that you can run from your home, providing a personal private server that runs various services, including a Bitcoin node. This solution is more geared towards those who have a strong emphasis on privacy and data sovereignty.
K3tan's Dell Node: shop.ministryofnodes.com
K3tan’s Node, this approach involves using a Dell Optiplex, which is a line of business desktop computers, to run a Bitcoin node. The idea here is to repurpose robust, readily available, and relatively inexpensive hardware for running a Bitcoin node.
Build your own Node with Raspberry Pi 4: littlebirdelectronics.com.au
For those who enjoy DIY projects, building a Bitcoin node with Raspberry Pi 4 components can be rewarding. You can purchase a Raspberry Pi 4, along with all necessary components like an SSD for storage, a reliable power supply, and a case. The Raspberry Pi 4 has enough processing power and memory to run a full Bitcoin node, making it a popular choice. You can install software like MyNode or Umbrel on your Raspberry Pi to get started.
