In today's digital landscape, privacy is paramount, not only when using blockchain technology but in every aspect of our online lives. Whether it’s browsing the web, communicating with others, or managing digital assets, your personal information is constantly at risk of being exploited by third-party entities.
At Dappnode, we bring peace of mind to anyone concerned about privacy and ownership by providing an alternative they can fully control, free from the data-exploitative practices of other products.
Our mission is simple: to transform the internet into a tool of freedom for everyone, empowering individuals to reclaim their privacy and ownership online. By giving users the ability to host their own nodes and manage their data, Dappnode provides a secure, decentralized alternative that puts control back into the hands of its users.
In our latest Dappnode Crash Course, we explored privacy-enhancing strategies specifically designed for Dappnode users. Whether you're concerned about data leaks or ensuring secure transaction submission, this comprehensive guide will help you boost your privacy with Dappnode. Here’s a detailed breakdown of what we covered:
1. What are RPCs and How Do They Impact Your Privacy?
When you connect to the blockchain via public RPCs (Remote Procedure Calls), your data may be exposed to third parties, posing a privacy risk. In our course, we explained the basics of RPCs and how they function within blockchain networks.
Using your own Dappnode’s RPC endpoint is a crucial step in safeguarding your privacy. By switching to a local node's RPC, you can significantly reduce the chance of third-party surveillance, as you'll control both the data queries and transaction submissions.
How to Switch to Your Own Node’s RPC:
- Navigate to your Dappnode's packages and locate the execution client for your desired network.
- Copy the Querying API URL and update your wallet’s network settings by replacing the public RPC with your Dappnode’s endpoint.
2. The Privacy Benefits of Running Your Own Node: Querying vs. Transactions
Running your own node can greatly enhance your privacy, especially when querying blockchain data. However, submitting transactions requires more caution. Transaction propagation in the mempool could potentially expose your node’s IP address.
For improved privacy, consider routing your node’s traffic through a VPN. This offers an added layer of protection, although you may experience a slight trade-off in terms of latency and validator performance.
3. How to Share Blockchain Nodes Securely with Friends and Family
Dappnode makes it easy to share your node securely with people outside your local network. Using HTTPS mappings, you can create custom URLs that allow trusted friends and family to access your node while maintaining their privacy.
Steps to Share Your Node:
- In the execution client’s network tab, create a new HTTPS mapping.
- Generate a unique subdomain and share the URL with those you trust.
- Set up port forwarding for external access.
4. Protecting Private UIs with HTTPS Authentication
When sharing UI dashboards or sensitive tools like Grafana or Web3Signer, Dappnode supports secure HTTPS authentication. This feature ensures that only authorized users can access these interfaces, providing a secure method for temporary access.
5. Leveraging Local Repositories: Ethereum and IPFS for Enhanced Privacy
Dappnode’s decentralized architecture, powered by Ethereum and IPFS, ensures that package management stays resilient and private. Users can access Dappnode’s DAppStore independently from centralized servers, offering both privacy and reliability.
6. Self-Host Your Mobile Backups with Owncloud
One of Dappnode’s most underrated features is the Owncloud package, which allows users to self-host their data, including contacts and mobile backups. This offers a secure alternative to relying on centralized services like Google or Apple for data storage.
7. Ethical Metrics: Receive Private Notifications via Tor
Privacy extends to notifications with Dappnode’s Ethical Metrics feature. By leveraging the Tor network, users can receive alerts without being tracked. This is a critical feature for anyone who values privacy in a decentralized environment.
How to Set Up Ethical Metrics:
- Go to the System > Notifications section of your Dappnode.
- Follow the documentation to set up notifications through Tor.
Conclusion: Take Control of Your Privacy with Dappnode
Enhancing privacy with Dappnode involves understanding the intricacies of node operation, secure transaction submission, and safe data sharing. By mastering Dappnode’s advanced privacy features, you can protect your digital footprint while benefiting from decentralization.
