Arbitrum is a layer 2 scaling solution for Ethereum, designed to improve efficiency and reduce the high transaction costs associated with using the Ethereum network. It is not a standalone cryptocurrency but rather a technology aimed at enhancing the Ethereum ecosystem.
Arbitrum was founded by Ed Felten, Steven Goldfeder, and Harry Kalodner, who are all computer scientists and experts in the field of blockchain technology. The project was initiated by Offchain Labs, a company focused on building scaling solutions for blockchain networks.
Arbitrum is based on a technology called Optimistic Rollup, which is a type of layer 2 scaling solution. It works by processing most transactions off-chain and then periodically batching the results back to the Ethereum mainnet. This batching process helps to reduce congestion on the main Ethereum network and lower transaction fees while still maintaining a high level of security and decentralization.
By processing most transactions off-chain, Arbitrum can significantly increase transaction throughput and reduce gas fees, making it more practical for various use cases. Arbitrum is designed to be compatible with existing Ethereum smart contracts, meaning that applications built on Ethereum can be easily migrated to Arbitrum without major code changes.
Arbitrum leverages Ethereum's security by periodically anchoring the sidechain's state on the Ethereum mainnet, ensuring that the assets and transactions on the sidechain are protected by Ethereum's robust security mechanisms. While most transactions are processed off-chain, the system still maintains a high level of decentralization as it relies on Ethereum's consensus mechanism and doesn't introduce new central points of control.
Arbitrum's transactions occur off-chain, processed by validators, ensuring faster and cost-efficient execution compared to the Ethereum mainnet. Validators generate proofs to verify correct transaction execution within the Ethereum virtual machine's rules. These proofs are bundled into batches with a Merkle root that represents the entire batch.
The Merkle root is anchored on Ethereum through the Arbitrum Bridge smart contract, ensuring the network's security and enabling the detection of any fraudulent activity. During a challenge period, users or validators can dispute the validity of transactions, leading to the reversal of invalid transactions and penalties for malicious actors. Once challenges are resolved, transactions are finalized.
The core component of Arbitrum's ecosystem is the Arbitrum protocol, which enables the implementation of Optimistic Rollup for scaling Ethereum. It allows developers to deploy smart contracts and decentralized applications (dApps) on the Arbitrum sidechain, taking advantage of its scalability benefits while remaining compatible with the Ethereum mainnet.
Arbitrum’s native token, ARB, plays a crucial role in the governance of the ecosystem. The project is making a significant shift towards decentralization through the creation of the Arbitrum DAO.
The Arbitrum DAO empowers ARB holders, granting them the right to participate in governance decisions. This means that ARB holders can actively vote on proposals that impact various aspects of the platform. These proposals encompass essential matters, such as feature additions, protocol upgrades, allocation of funds, and even the election of a Security Council to ensure the network's security and integrity.
Arbitrum has a series of exciting developments planned. One significant milestone is the introduction of their own layer-three solution, dubbed Orbit. This innovation aims to further enhance scalability and throughput, providing even more efficient transaction processing on the Arbitrum network.
In a move to foster developer-friendly environments, Arbitrum will also enable programmers to deploy programs written in popular languages such as Rust, C++, and others, using a tool called Stylus. This opens up new possibilities for developers to build sophisticated decentralized applications that integrate seamlessly with the Arbitrum ecosystem.
The total supply of ARB tokens is fixed at 10 billion. The distribution of these tokens is as follows: 42.78% (4.278 billion) is allocated to the Arbitrum DAO treasury, 26.94% (2.694 billion) to Offchain Labs teams and advisors, 17.53% (1.753 billion) to investors, 11.62% (1.162 billion) for an airdrop to users, and 1.13% (113 million) for an airdrop to DAOs.
As of July 21, 2023, there are 1,275,000,000 ARB in the current circulation.
Average Fees on the Arbitrum
Unlike ETH on the Ethereum network, ARB does not function as a gas fee token on Arbitrum. Instead, transactions and fees on the network are settled in ETH or any other ERC-20 token supported by DApps. This means that ARB holders are not required to spend their tokens to use Arbitrum services; instead, they can stake their ARB tokens and earn fees as a reward for contributing to the network's security and stability.
As of July 2023, the average transaction fee on Arbitrum is approximately $0.368 per transfer, while on Optimism, it is slightly higher, around $0.682 per transaction. These figures may fluctuate based on network activity and demand.
How to buy ARB on SwapSpace
On this page, we put USD in the “You send” and ARB in the “You get” sections in the widget. USD is the default, but you can choose your preferred fiat currency. Put in the amount of fiat you want to spend. Next, press the ”View offers” button and choose a provider.
Fill in the “Enter the recipient address” field with the destination Arbitrum address. Check the information carefully and click the “Next” button. After reading the special terms and conditions in the next window, click “Next” again.
At this point, you will either see our partner’s widget or be redirected to another page, depending on the chosen provider. You will be asked to verify your identity, as this is standard practice for the services that work with fiat money. Follow the provider’s instructions on the screen.
After completing the KYC procedure, fill in your credit card information. At this point, everything is in place and your transaction will start.
Wait for the transaction to process. You’ll see a message when it’s completed. A window with your transaction details will also appear; from there, you can also create another crypto-fiat exchange.
