Introduction to VeChain

2. Unique Features and Consensus

This lesson introduces VeChain, its foundational blockchain (VeChainThor), and the core features that support its focus on real-world Web3 applications.

Prerequisites

The VeChainThor Engine

Now, let’s see what makes the VeChainThor engine so special. ⚙️

One major hurdle for Web3 is gas fees. VeChainThor uses Fee Delegation.

Think of Fee Delegation like a "prepaid tab" where sponsor accounts pay transaction fees for users. This reduces the entry barrier for everyone!

To keep costs stable, VeChain uses a Dual-token system. This ensures that transaction fees stay predictable even when network demand is high.

"But how is the network secured?" Good question!

How is the network secure?

Good question! While the platform started with Proof of Authority, VeChainThor recently updated its heartbeat!

It has changed its consensus to Delegated Proof of Stake (DPoS) via Hayabusa upgrade (live Dec 2025), enhancing decentralization with Validators and Delegators while retaining predictable fees.

Finally, strategic decisions aren't made by one person. They happen on the VeVote platform, where stakeholders ensure the network stays true to its values.

You're a natural! You've mastered the basics of the VeChainThor architecture. 🏆

Common Pitfalls to Avoid

Don't forget that the network is decentralized! While founded by Sunny Lu, strategic growth is managed by the community through VeVote.
