Blockchain Arbitrum is a layer-2 solution project that aims to improve the speed, scalability, and privacy of Ethereum smart contracts. It allows developers to execute unmodified Ethereum Virtual Machine (EVM) contracts and transactions at layer-2, while maintaining Ethereum's layer-1 security. It was created to address some of the challenges of current Ethereum-based smart contracts, such as long transaction times and high execution costs.
The History of Arbitrum
Arbitrum was developed by Offchain Labs, a company founded in 2018 by a team of computer scientists from Princeton University. The team consists of Ed Felten, former Deputy U.S. Chief Technology Officer and Professor of Computer Science and Public Affairs at Princeton; Steven Goldfeder, a postdoctoral researcher at Cornell Tech and co-author of the book Bitcoin and Cryptocurrency Technologies; and Harry Kalodner, a Ph.D. candidate in Computer Science at Princeton.
The team leveraged their expertise in cryptography, distributed systems, and programming languages to create Arbitrum, a novel optimistic rollup protocol that uses a combination of on-chain and off-chain techniques to achieve scalability and privacy. Arbitrum was first introduced in a research paper published in 2018, and later presented at the Scaling Ethereum workshop in 2019.
In 2019, Offchain Labs raised $3.7 million in a seed round led by Pantera Capital, with participation from Compound VC, Blocknation, and other investors. In 2021, the company raised $20 million in a Series A round led by Polychain Capital, with participation from Coinbase Ventures, Alameda Research, Mark Cuban, and other investors. In August 2021, the company raised $100 million in a Series B round led by Lightspeed Venture Partners, with participation from Ribbit Capital, Redpoint Ventures, Pantera Capital, and other investors.
The Launch of Arbitrum
Arbitrum launched its mainnet beta in May 2021, after undergoing extensive testing and auditing. The mainnet beta allowed developers to deploy and test their smart contracts on Arbitrum, while users could interact with them through a web interface or a browser extension. The mainnet beta also supported interoperability with Ethereum, allowing users to transfer ETH and ERC-20 tokens between the two networks.
In September 2021, Arbitrum announced that it had reached over $2.2 billion in total value locked (TVL) on its network, making it one of the most popular layer-2 solutions in the market. The network also attracted over 250 projects, including Uniswap, Aave, Chainlink, MakerDAO, SushiSwap, and others, that integrated or planned to integrate with Arbitrum.
On March 23, 2023, Arbitrum held its initial coin offering (ICO) for its native token, ARB. The token sale was conducted on Galaxy, a decentralized platform for launching and trading tokens. The token sale raised $123.7 million, selling 21% of the total supply of 10 billion ARB tokens at a price of $1.35 per token. The token sale was oversubscribed by 4 times, indicating a high demand for the token.
The ARB token serves as the governance and utility token of the Arbitrum network. It allows holders to participate in the governance of the network, such as proposing and voting on protocol upgrades, parameter changes, and dispute resolution. It also allows holders to pay for fees and services on the network, such as gas fees, validator fees, and data availability fees.
The Future of Arbitrum
Arbitrum aims to become the leading layer-2 solution for Ethereum, offering a scalable, secure, and user-friendly platform for smart contract development and execution. It also aims to foster a vibrant and diverse ecosystem of projects and users that leverage its technology and token.
Arbitrum has several plans and features in the pipeline, such as:
- Launching its Arbitrum DAO, a decentralized autonomous organization that will manage the network's treasury, funds, and governance.
- Airdropping 11.5% of the ARB supply to users who meet certain criteria, such as using the network, holding ETH or ERC-20 tokens, or being part of a DAO that builds on Arbitrum.
- Supporting more bridges and integrations with other layer-1 and layer-2 networks, such as Polygon, Avalanche, Solana, and others.
- Improving its user experience, developer tools, documentation, and community support.
- Exploring new use cases and innovations for its protocol, such as zero-knowledge proofs, privacy-preserving computation, and cross-chain communication.
Arbitrum is a promising project that has the potential to revolutionize the Ethereum ecosystem and beyond. It offers a solution that addresses some of the pain points of smart contract development and usage, while maintaining compatibility and security with Ethereum. It also has a strong team, a growing community, and a solid roadmap that could drive its adoption and growth in the future.
Arbitrum is a project that could be worth watching in the upcoming bull market, as it could benefit from the increasing demand for scalable, low-cost, and high-performance blockchain platforms. Arbitrum could also see its token value appreciate, as it reflects the network's utility, governance, and network effects.
