Problem / Why

New developers often don’t understand what a node is in TON, who operates nodes (validators vs non-validators), and how apps actually reach the network (wallets, APIs, liteservers). This causes confusion early in onboarding.

What to do

Add a beginner-friendly section that explains:

• What a node is (stores/serves blockchain data, participates in propagation/validation)
• Who runs nodes (validators, infrastructure providers, explorers/indexers, projects, community)
• How users/apps interact (wallet/app → API/liteserver → TON nodes)

Diagram to be added

A simple diagram showing flow, e.g.:

User / Wallet / DApp
→ API provider / Liteserver (gateway)
→ TON Nodes (Full nodes)
→ Validators (subset that produces blocks)

Acceptance criteria

• The page contains a clear definition of “node” + “who runs it” in plain language.
• Includes one diagram that matches the text and helps a beginner visualize the system.
• Links to deeper reading (Nodes / Validators / Liteservers) as optional follow-ups.
