Depth Analysis of Ethereum Scaling Solution Arbitrum

Arbitrum is an Ethereum layer 2 scaling solution developed by Offchain Labs, based on Optimistic Rollup technology. This solution improves transaction speed and reduces costs by processing transactions off-chain and submitting the compressed data to the Ethereum mainnet.

Technical Features

The main technical features of Arbitrum include:

1. Multi-round fraud proof interaction, reducing gas consumption for a single challenge.
2. High compatibility with EVM, almost 100% compatible with existing Ethereum applications.
3. Use WebAssembly architecture to replace the original AVM architecture.
4. Use Geth instead of a custom EVM simulator
5. ArbOS rewritten in Go, optimizing batch processing and compression system.

Recent Developments

In 2022, Arbitrum underwent several important upgrades:

• Launched the Arbitrum Nova chain, utilizing AnyTrust technology, designed specifically for gaming and social applications.
• The mainnet has been upgraded to the Nitro version, significantly improving performance.
• Released the Stylus programming environment, supporting development in languages such as Rust and C.

In March 2023, Arbitrum announced the launch of the governance token ARB, with a total supply of 10 billion tokens, of which 11.62% will be airdropped to users.

Ecological Status

Arbitrum is currently the largest Layer 2 network on Ethereum by TVL, reaching $3.85 billion, accounting for 56% of the total Layer 2 TVL.

The main ecological projects include:

• DeFi: GMX, Camelot, RDNT, etc.
• Games: Treasure DAO, Trident, etc.

Future Development

Arbitrum will focus on the following aspects in the future:

1. Continue technical upgrades to improve performance and decentralization.
2. Expand ecological applications, especially in the fields of social and NFTs.
3. Improve the token economic model and governance mechanism

Overall, Arbitrum is expected to maintain rapid growth in 2023 and continue to consolidate its leadership position in Layer 2.
