What is Arbitrum ?
Arbitrum: the solution to make Ethereum faster and cheaper ⚡🪙
Ethereum is powerful but often slow and expensive. That’s where Arbitrum comes in — a layer 2 solution that cuts costs and boosts speed while maintaining Ethereum’s security. With its native token ARB, the project moves toward full decentralization.
So how does it work? Why is it popular? And what’s ARB really for? Let’s break it down.

What is Arbitrum?
Arbitrum is a layer 2 blockchain built on top of Ethereum. Its goal? Make Ethereum more efficient.
Instead of processing everything on Ethereum, Arbitrum handles transactions on its own chain and then sends a compressed summary back to Ethereum. Result? 💨 Faster and cheaper.
How does Arbitrum work?
Arbitrum uses a clever technique called optimistic rollups:
🔹 Bundles multiple transactions together
🔹 Sends those bundles to Ethereum
🔹 Uses fraud proofs to ensure honesty
You get the security of Ethereum, but with a big boost in performance and lower fees.
What is the ARB token for?
ARB isn’t for gas fees. It’s a governance token — giving power to the community.
🗳️ With ARB, holders can:
- Vote on protocol upgrades
- Shape the Arbitrum DAO’s decisions
- Allocate funds from the treasury
It’s about creating a decentralized future for layer 2.
Why is Arbitrum popular?
Arbitrum is winning hearts and wallets:
🔥 Very low fees
🚀 Fully compatible with Ethereum apps
👾 Strong DeFi presence with Uniswap, GMX, Aave
🌱 Growing ecosystem with hundreds of dApps
It’s often the most used layer 2 in terms of total value locked (TVL).
The drawbacks to watch
Arbitrum is strong, but not perfect:
⚠️ Still relies on Ethereum for final security
⚠️ 7-day withdrawal delay for some operations
⚠️ Centralization concerns in validator management
Developers are working to improve these points and move to full decentralization.
Arbitrum vs other solutions
