Understanding The Arbitrum Bridge: An Ultimate Guide

What is Arbitrum?

Arbitrum is a layer-2 blockchain that facilitates a better user experience on Ethereum. It ensures a cheaper and faster throughput while leveraging Ethereum’s security.

Offchain Labs – a team of reputable engineers with diverse backgrounds behind the protocol. Ed Felten, Harry Kalodner, and Steven Goldfeder founded Offchain Labs in 2018. The New York-based company researches various technological possibilities to enhance Ethereum performance and throughput. There are mainly two reasons why so many developers choose the Arbitrum network: faster transaction processing and lower transaction fees.

  • Faster Transaction Processing. Today, Ethereum network operate under 15 to 20 TPS, a relatively low figure. The Arbitrum network presents a viable tech stack to skyrocket the performance of Ethereum. Analysis shows that it can conveniently process around 40,000 TPS.

  • Lower Transaction Fees. A significant percentage of validators need to confirm the genuineness of a transaction before it can go through on Ethereum. This results in massive backlog in the mempool, with only a small slot being processed per instance. Hence, some traders often add additional fees to their usual gas fees, driving the cost of Ethereum transactions.

The Arbitrum network provides a cheaper option. According to Nansen, a Web3 data analytics firm, the average daily fee on Arbitrum was $.2, compared to $6.5 for Ethereum.

Arbitrum ecosystem

  1. DeFi and dApps

Decentralized finance is one of the significant areas where Arbitrum ecosystem is booming. The Arbitrum network is home to GMX, Buffer, and Kromatika, and 100 other crypto projects worth over $180 billion in total.

Arbitrum network has almost 100 decentralized applications, including blue-chip dApps, trading protocols, NFT marketplaces, DeFi projects, and Gaming projects. Examples include the most popular Ethereum dApps, such as OpenSea, Stargate Finance, and Uniswap. The huge user activities on these DApps have a corresponding effect on the overall user activity.

Crypto degens and retail investors are trooping to it because of the airdrops. A consistent pattern of the past months was that Arbitrumn ecosystem projects gave the most jaw-dropping airdrops.

  1. Insights Into Arbiscan

The first block explorer for contracts or transactions carried out is called Arbiscan. The second block explorer for smart contracts deployed with the Nitro Goerlione is Goerli Arbiscan.

Here are a few data that point to its strengths and fast-rising nature, according to Arbiscan:

  • Processed up to 576,012 daily accepted transactions.

  • Almost 3 million unique addresses.

  • An average of 100 to 300 smart contracts deployment daily.

To a large extent, Arbiscan has a similar UI to Etherscan. Besides providing data on specific and generic transactions, Arbiscan also has a developer suite where developers can verify contracts and tap into its API and other functionalities.

How does Arbitrum Work?

Two Mainnets and One Testnet. Arbitrum network has two different mainnets and one testnet, unlike other blockchains that will have a single mainnet. Arbitrum One is the first mainnet, while Nova is the second. The Offchain Labs team introduced the Nitro tech stack in late 2022.

AVM architecture. Arbitrum is fully compatible with the Ethereum blockchain development environment and tooling. Solidity and Vyper developers can build smart contracts for Arbitrum bridge. They can also use frameworks such as Foundry, Hardhat, and Truffle. In essence, Ethereum smart contracts and Ethereum dApps work the same in Arbitrum network. It also has its virtual machine called the Arbitrum Virtual Machine. Offchain Labs built their custom AVM to solve the following three problems in EVM:

  1. Execution flow and structure . Arbitrum has an operating system at its core called ArbOs. The ArbOS ensures the solitary existence, optimal performance, and efficient analytics of smart contracts. Embedding such an OS into an L1 infrastructure cannot be cost-efficient and L2-native. This was why the Offchain Labs team engineered a custom virtual machine to host the ArbOs natively.

  2. Dispute settlement speed. When validators disagree, Ethereum virtual machine wouldre-execute the cause. But AVM has a custom protocol for dispute management, so that proving would not be carried out on a standard virtual machine. This is crucial for speed and maximal efficiency.

  3. Native tuples. The EVM necessitates any L2 to have its custom Merkle-hashing parameters. Arbitrum uses tuples to define and reference types in its Merkle tree. The tuples can be referenced in looking up the Merkle root of any transaction on the EVM Merkle tree. Due to its relativity to the EVM Merkle tree, the AVM became necessary since the tuple method will be native to it.
