🌐 Blockchain vs. Centralized Networks

🔑 What is the Blockchain?

• Unlike the Internet, the Blockchain is made up of millions of individual computers around the world.

• These devices run specialized node software, contributing:

  • Data processing

  • Computing power

  • Energy

  • Connectivity

• This collective effort supports blockchain applications, securely stores data, and validates transactions.

• Nodes are owned and operated by private individuals, small/medium businesses, and others.

• Node operators are compensated for their contributions to the blockchain.

• Blockchain software constantly verifies that each node is active and providing resources.

👉 In short: A Blockchain Node is a software application installed on a computer, mobile device, or other internet-enabled device that helps operate the blockchain network.

🔑 How Does It Differ from a Centralized Network?

• The traditional Internet backbone is powered by large, centralized data centers owned by companies like Amazon and Google.

• These organizations:

  • Set the standards for information published and consumed online.

  • Track user behavior, preferences, and personal information.

  • Monetize this data by leveraging control of the infrastructure.

• In centralized networks, publishers must lease resources (storage, compute power, energy, connectivity) from these data centers in order to publish content and run applications.

👉 In contrast, blockchain networks are distributed — no single organization owns or controls the infrastructure.
