| Security Rating | C |
Arbitrum’s C rating reflects its moderate node count and developer activity, alongside its low Nakamoto Coefficient, indicating a stable but not leading security posture with some centralization concerns. |
| Reliability Rating | B |
As a Layer 2 solution, Arbitrum improves Ethereum's transaction speed and reliability, maintaining low error rates. |
| Performance Rating | C |
Arbitrum’s C rating reflects its moderate performance in block time and transaction throughput, alongside balanced transaction finality, indicating a stable but not leading performance posture. |
Arbitrum One is a Layer 2 scaling solution for Ethereum that aims to improve its transaction speed and reduce costs while leveraging Ethereum's security.
Consensus mechanism
It uses Optimistic Rollup technology, where transactions are batched off-chain and periodically reported back to the Ethereum mainnet.
This approach assumes transactions are valid by default, with a dispute resolution mechanism in place for potential fraud.
This significantly reduces the computational load on the Ethereum mainnet, allowing for faster transaction speeds and lower fees. The system relies on a network of validators that monitor and report any fraudulent activity, ensuring the integrity of the transactions processed on the Arbitrum One chain.
The platform supports EVM compatibility, allowing developers to deploy Ethereum-based smart contracts without any modifications. This feature makes it an attractive option for developers looking for scalable solutions without departing from the Ethereum ecosystem.
Use cases
Use cases for Arbitrum One are vast and include decentralized finance (DeFi) applications, non-fungible tokens (NFT) marketplaces, and gaming platforms. By offering reduced transaction costs and latency, Arbitrum One enables these applications to operate more efficiently, facilitating a smoother user experience and encouraging broader adoption of blockchain technology. As the blockchain space continues to evolve, Arbitrum One stands out as a key player in the quest for scalable, secure, and efficient blockchain infrastructures.
