Arbitrum is a Layer-2 scaling solution built on Ethereum, leveraging optimistic rollups to enhance transaction speed and reduce costs while maintaining Ethereum’s security. Fully compatible with Ethereum’s ecosystem, Arbitrum processes thousands of transactions per second at minimal fees, making it a leading Layer-2 protocol in the blockchain space.
How Arbitrum (ARB) Works
Arbitrum’s optimistic rollup technology bundles multiple transactions off-chain, submitting only cryptographic proofs to Ethereum. Key features include:
- EVM Compatibility: Runs unmodified Ethereum smart contracts.
- High Throughput: Processes thousands of transactions per second.
- Low Fees: Costs a fraction of Ethereum’s Layer-1 fees.
- Decentralized Validation: Validators stake ARB tokens to secure the network.
