As Ethereum grows in popularity, it faces inherent challenges, such as slow transaction speeds, high gas fees, and network congestion. While Ethereum’s base layer (Layer 1) remains secure and decentralized, it struggles to meet the demands of an expanding global user base. This is where Layer 2 solutions come into play.
Arbitrum is one of the most well-known Layer 2 protocols designed to address these scalability challenges. It operates atop Ethereum, enhancing its transaction throughput and reducing transaction costs, without compromising security.
In this article, we will explore Arbitrum, how it works, how to buy ARB tokens (the native token of the Arbitrum network), and where to purchase them.
What is Arbitrum?
Arbitrum is a Layer 2 scaling solution for Ethereum developed by Offchain Labs. Its primary goal is to alleviate Ethereum’s scalability issues by providing faster and cheaper transactions. Arbitrum is built on optimistic rollups, which enables Ethereum transactions to be executed off-chain while ensuring they remain secure and validated by the Ethereum network.
Background on Ethereum’s Scalability Problem
Ethereum has become the foundation for various decentralized applications (dApps) and smart contracts. However, users began experiencing congestion and high transaction costs as the network grew in popularity. Ethereum’s base layer can only process a limited number of transactions per second (TPS), which causes slow processing times and high gas fees during times of heavy use.
To solve this issue, the Ethereum community has explored multiple Layer 2 solutions, with Arbitrum standing out due to its simplicity and effectiveness.
What Are Layer 2 Solutions?
Layer 2 solutions refer to secondary frameworks built on top of an existing blockchain (in this case, Ethereum) to improve scalability, reduce costs, and enhance transaction throughput. These solutions process transactions off the main chain but use it for security and settlement. Arbitrum is one such Layer 2 solution that enhances Ethereum’s functionality by using an innovative approach known as optimistic rollups.
Why Arbitrum?
Arbitrum’s key appeal lies in its ability to process transactions off-chain while maintaining the security and decentralization of Ethereum. It offers Ethereum compatibility, meaning dApps and smart contracts built on Ethereum can seamlessly migrate to Arbitrum without requiring significant code modifications.
How Does Arbitrum Work?
Arbitrum works by utilizing a technology called optimistic rollups. But what exactly does this mean?
Optimistic Rollups Explained
Optimistic rollups are a scaling solution designed to improve the throughput of Ethereum’s network. Arbitrum batches multiple transactions together and processes them off-chain. These bundled transactions are called rollups.
The “optimistic” part refers to how Arbitrum assumes that transactions in each rollup are valid by default. Instead of verifying every single transaction in real-time, Arbitrum assumes most transactions are correct and only verifies them if a dispute arises. This significantly reduces the computational burden and allows for much faster transaction processing compared to Ethereum’s Layer 1.
How Arbitrum Handles Transactions
- Transaction Submission: Users submit transactions to Arbitrum, which processes them in batches off-chain.
- Transaction Rollups: Arbitrum bundles these transactions into a rollup and submits them to the Ethereum main chain (Layer 1) for settlement.
- Fraud Proofs: If any participant believes a transaction in the rollup is invalid, they can submit fraud proof to challenge the transaction. If the challenge is valid, the incorrect transaction is reverted, and the honest party is rewarded.
- Finality on Ethereum: After the transactions are rolled up and the validity is confirmed (either through no disputes or after a successful fraud challenge), the state changes are committed to the Ethereum blockchain, ensuring finality.
Benefits of Arbitrum
- Faster Transactions: By executing transactions off-chain, Arbitrum can handle thousands of transactions per second (TPS), which is far greater than Ethereum’s base layer.
- Lower Gas Fees: Since transactions are processed off-chain, the cost associated with each transaction is significantly reduced.
- Security: Arbitrum leverages Ethereum’s security model. Any disputes are resolved through fraud proofs that involve Ethereum’s Layer 1, ensuring that Arbitrum benefits from Ethereum’s security without compromising decentralization.
- Compatibility: Developers do not need to rewrite their Ethereum-based smart contracts. Arbitrum supports all Ethereum dApps and decentralized finance (DeFi) protocols, making it easy for Ethereum-based projects to transition to Arbitrum.
How to Buy Arbitrum (ARB Token)?
Arbitrum has its native token, ARB, which is used for various purposes within the network, including governance and paying transaction fees. If you’re looking to purchase ARB tokens, here’s a step-by-step guide on how to do so.
Step 1: Choose a Cryptocurrency Exchange
Arbitrum (ARB) is listed on various centralized exchanges (CEXs) and decentralized exchanges (DEXs). The first step is to decide where to buy ARB tokens. Below are the most common platforms to purchase ARB:
Centralized Exchanges (CEXs)
- Binance: One of the world’s largest and most popular cryptocurrency exchanges. Binance offers ARB trading pairs and makes it easy to buy with a credit card or bank transfer.
- Coinbase: Another popular exchange that supports ARB tokens. Coinbase is known for its user-friendly interface, making it an excellent choice for beginners.
- Kraken: A well-known exchange that offers both spot trading and futures trading for ARB tokens.
- FMCPAY: FMCPAY is a platform that offers a user-friendly experience for buying and trading cryptocurrencies like ARB.
Decentralized Exchanges (DEXs)
- Uniswap: One of the largest decentralized exchanges, Uniswap allows users to trade ARB tokens directly from their wallets without relying on a central authority.
- SushiSwap: Another decentralized platform where you can exchange ARB tokens in a peer-to-peer manner.
Step 2: Set Up a Cryptocurrency Wallet
To hold and manage your ARB tokens, you’ll need a secure cryptocurrency wallet. Here are a few popular options:
- MetaMask: A widely used browser extension wallet that works well with decentralized exchanges like Uniswap and SushiSwap.
- Hardware Wallets: If you’re looking for enhanced security, consider using hardware wallets like Ledger or Trezor, which store your tokens offline.
- Trust Wallet: A mobile wallet that supports Ethereum and ERC-20 tokens like ARB.
Step 3: Buy ARB Tokens
Once your exchange account is set up and your wallet is ready, follow these steps:
- Deposit Funds: Deposit fiat currency (USD, EUR, etc.) into your exchange account or transfer cryptocurrencies like Ethereum (ETH) to use in trading.
- Place a Buy Order: Navigate to the ARB trading pair (e.g., ARB/ETH or ARB/USDT) and place a buy order for the desired amount of ARB tokens.
- Transfer to Wallet: After your purchase is complete, withdraw your ARB tokens from the exchange to your wallet for added security.
