Why Ubuntu for Decentralized Applications?
Ubuntu servers are a top choice for deploying decentralized applications on Ubuntu servers due to their reliability, open-source nature, and extensive community support. Unlike traditional centralized systems, DApps require a distributed architecture, and Ubuntu’s lightweight, secure environment excels here.
Ubuntu supports tools like IPFS for file storage and blockchain nodes for transaction processing, making it a go-to platform in 2025.
Key Benefits:
- Regular updates & firewall options for enhanced security
- Cloud compatibility (AWS, Azure, DigitalOcean)
- Optimized resource management for better performance
Understanding Blockchain and Decentralized Tech
Blockchain is the backbone of decentralized applications, enabling trustless, transparent state management and smart contracts. However, storing large files like images or web front-ends on blockchain is inefficient.
Enter IPFS (InterPlanetary File System):
- Peer-to-peer, content-addressable storage
- Unique content identifier (CID) for each file
- Ensures integrity and deduplication
Combining IPFS + Blockchain = Powerful DApp Stack
- Blockchain handles logic and value
- IPFS manages decentralized content delivery
Tools You’ll Need
Before diving into deploying decentralized applications on Ubuntu servers, gather these essentials:
- Ubuntu Server (20.04 or 22.04 LTS recommended)
- Go (programming language for IPFS and blockchain tools)
- IPFS (decentralized file storage)
- IPFS-Cluster (data replication)
- Blockchain Node Software (e.g., Geth, Solana)
- Command Line Access (SSH)
- Cloud VMs (e.g., DigitalOcean, AWS)
