What is ARBITRUM?

Arbitrum is a solution that helps make transactions faster and cheaper on the Ethereum blockchain. It does this by using a technique called Layer 2 scaling.

Layer 2 scaling is a way to make the Ethereum blockchain work more efficiently. It does this by moving some of the complex tasks to another chain called Layer 2.

The main Ethereum chain, known as Layer 1, still keeps track of the important data.

Arbitrum specifically focuses on handling transaction processing and batching for the Ethereum blockchain. By doing this, it helps reduce congestion and makes transactions less expensive.

For example, popular projects like Sushiswap and Aave use Arbitrum to make their swaps more efficient and to lower the fees associated with these transactions.

Quick Facts

1. Arbitrum (ARB) is the native governance token for the Arbitrum blockchain.

2. It is an ERC-20compatible token, which means it follows a set of rules that allow it to work smoothly on the Ethereum network.

3. The primary purpose of ARB is to facilitate value transfers, serve as an investment asset, and enable token holders to participate in governance decisions.

4. ARB tokens were distributed through an airdrop event in 2023, with specific eligibility criteria for users to qualify.

How does Arbitrum work?

Abritrum has a special solution called Layer 2 that helps process transactions more efficiently. They use something called blockchain rollups to do this.

Rollups work by processing transactions outside of the main blockchain before confirming them on the blockchain. This two-layer approach allows the blockchain to verify a group of transactions together instead of individually.

What makes this solution different from other Layer 2 methods like sidechains is that rollups rely on the security of the main blockchain.

Abritrum's specific type of rollup is called optimistic rollups. They use this type of rollup for their scaling solution.

Fun fact : Optimistic rollups bundle and compress transactions off-chain, reducing gas fees and optimizing block space on the Ethereum blockchain

What is the Arbitrum (ARB) token used for?

The Arbitrum token, known as $ARB, is a special digital token that works on the Arbitrum blockchain. It follows certain rules, called ERC-20, which make it compatible with other tokens on the Ethereum network. You can use $ARB to do different things like sending it to others, investing it, or voting on important decisions.

In 2023, there was a very exciting event called an airdrop where people could get free $ARB tokens. However, not everyone could get them. To be eligible, you had to meet at least three out of these six conditions:

1. Move your assets to either Arbitrum One or Nova using a special connection called a bridge.

2. Do transactions on the Arbitrum blockchain regularly for at least two months before a specific date in February 2023.

3. Interact with at least four smart contracts on Arbitrum or do four transactions on the network.

4. The total value of all your transactions should be at least $10,000.

5. Deposit at least $10,000 on Arbitrum One.

6. Use a social chain called Arbitrum Nova for at least three transactions.

If you met at least three of these conditions, you could claim the $ARB tokens as a reward.

Who invented Arbitrum?

The team behind Arbitrum is Offchain Labs, a company started in 2018 by Ed Felten, Steven Goldfeder, and Harry Kalodner. They introduced the solution in 2018 through a presentation and a whitepaper at Princeton University.

After that, in 2020, they released the first version of Arbitrum and tested it in a beta phase. Finally, in August 2021, they launched it on the Ethereum mainnet. Many people in the Ethereum community became interested in Arbitrum after its launch, and popular projects like Uniswap, Chainlink, and Aave started using it.

What makes Arbitrum stand out?

Arbitrum stands out among other solutions that address Ethereum's limitations. Here's why it is unique and better:

1. Low transaction fees

Arbitrum is designed to be efficient, resulting in significantly lower transaction fees compared to Ethereum. This makes it more appealing for validators and users. While Ethereum may charge tens of dollars for a transaction, Arbitrum only costs a few dollars.

2. Full EVM compatibility

Arbitrum is fully compatible with the Ethereum Virtual Machine (EVM) at a detailed level. This means that developers who already understand Ethereum programming languages can easily switch to Arbitrum and start building decentralized applications (dApps) without much hassle.

3. Extensive documentation

Arbitrum provides comprehensive developer documentation, making it easier for developers to quickly get started with building on the platform. They can utilize existing tools and resources, thanks to Arbitrum's compatibility with the Ethereum ecosystem.

Overall, Arbitrum's combination of affordability and ease of adoption makes it a promising solution for scaling Ethereum. It not only reduces transaction costs but also empowers developers to create innovative decentralized applications for the future.

Arbitrum vs Other Layer-2s

When comparing Arbitrum to other Ethereum Layer 2 solutions like Polygon and Optimism, there are some notable differences.

Arbitrum is an optimistic rollup chain that works with Ethereum's consensus protocol. It supports all Ethereum Virtual Machine (EVM) programming languages, can handle up to 40,000 transactions per second (TPS), and recently airdropped its native governance token called $ARB.

Polygon, on the other hand, is a sidechain that uses a proof-of-stake (PoS) mechanism for consensus. It is compatible with Solidity and Vyper, two of the EVM languages. Polygon has a higher speed of 65,000 TPS and has its native token called $MATIC.

Optimism is also an optimistic rollup chain that uses Ethereum's consensus protocol. However, it is only compatible with the Solidity programming language. Optimism has a lower speed of 2,000 TPS and has its native token called $OP. It's important to note that Optimism relies on the Ethereum Virtual Machine, unlike Arbitrum, which has its own.

As of April 1, 2023, Arbitrum has the highest total value locked, which shows that the blockchain community has great trust in its technology. Its compatibility with all EVM languages makes it a strong competitor in the market.

How to buy Arbitrum (ARB)?

Purchasing ARB on a decentralized exchange is a fairly simple process.

First, you need to transfer your $ETH from the Ethereum blockchain (Layer 1) to Arbitrum using a bridge. Once your assets are bridged to Arbitrum, you can use Sushiswap, an exchange on Arbitrum, to convert your Ethereum into ARB using its easy-to-use swap interface.

Please note that you can technically bridge other cryptocurrencies on the Arbitrum network, such as $USDC, to buy ARB, but you still need some $ETH to cover the transaction fees.

However, it's important to understand that buying new cryptocurrencies like ARB (or any cryptocurrency) can be risky. New cryptocurrencies usually have fewer supporters, so if someone with a large amount of ARB decides to sell, it can greatly affect the price.

Additionally, new cryptocurrencies are often subject to speculation and uncertainty, leading to sudden and unpredictable price changes.

Before buying any cryptocurrency, it's crucial to conduct thorough research. Pay attention to the track record of the team behind the cryptocurrency, the potential use cases of the currency, and evaluate the risks and potential rewards associated with investing in a newer cryptocurrency.
