Beginner Guide to Arbitrum Blockchain

Originally published in October 31, 2008 by the pseudonymous inventor Satoshi Nakamoto, the Bitcoin Whitepaper is one of the most groundbreaking works of computer science since the internet, which lays the foundations of electronic peer-to-peer cash and its underlying blockchain technology. The paper is titled Bitcoin: A Peer-to-Peer Electronic Cash System

The Bitcoin Whitepaper is only nine pages long and is a proposal for a trustless system of electronic transactions. The Bitcoin network creates a structure for making payments without a trusted third party acting as intermediary. The Bitcoin Whitepaper in simple language attempts to translate complex technological concepts into easy-to-understand terminology.

This was Satoshi’s idea for an electronic currency that can make transactions with low costs while using no financial institutions or third parties. Instead of using a centralized server, it is structured to use many terminals connected over a peer-to-peer (P2P) network. It explains how the proof of work structure renders falsification of transaction information nearly impossible. For those who are interested, the original document can be read or downloaded at

Ethereum is a popular platform to develop decentralized apps (DApps). However, Ethereum has experienced a rapid rise in adoption in recent years. This has led to a surge in transaction fees and resulted in massive congestion. 

The Ethereum community created a strategy called Arbitrum to solve network problems. 


What Is the Arbitrum? 

Arbitrum is a layer-2 solution that enhances the capabilities of the Ethereum smart contract — increasing their speed and scalability while adding additional privacy features. 

This platform allows developers to run unmodified Ethereum Virtual machine (EVM) contracts and Ethereum transactions on a second level while still enjoying Ethereum’s outstanding layer 1 security. 

It was created to fix some of the weaknesses of Ethereum-based smart contract technology. These include low efficiency and high execution costs, which can lead to a poor user experience and make transacting expensive. 

Arbitrum employs a technique called transaction rollups to store batches of transactions submitted to the Ethereum mainchain. The sidechain can be used to execute these transactions on a low-cost, scalable layer 2, while still leveraging Ethereum to guarantee correct results. This allows Ethereum to reduce its storage and computational burden, as well as allow for new layer 2-based DApps. 


How does Arbitrum Work? 

Arbitrum is a type of technology that’s known as the optimistic rolling up. This technology allows smart contracts from Ethereum to scale through the transmission of messages between smart contracts in Arbitrum’s second chain layer and smart contracts in Ethereum. 

Arbitrum will also record transaction results in the main chain. This process can dramatically increase the system’s efficiency and working speed. 

Any validator can later post a rollup and confirm another block’s validity. Rollup refers to how validators can use public information from optimized logs to reconstruct the chain history. This protocol guarantees that the code runs correctly. 

The future versions of Arbitrum will include two additional modes: sidechain and AnyTrust channel. 

Individual nodes can join the Arbitrum blockchain, just like other blockchains. The chain’s state is monitored by validator nodes. Full nodes also participate in the monitoring of the chain. This helps to merge layer 1 transactions. Transactions sent to the layer-1 chain by aggregates are eligible for rewards in ETH. Other transaction fees are paid to network participants such as validators. 

The layer 2 project introduces a difficult step in block rollup. This involves other validators checking the block’s accuracy and issuing a challenge if they believe it to be false. The block will be ruled incorrectly or the challenge is unfounded, and the validator who lies about it will have their assets taken. This ensures that validators are fair and take responsibility for any violations. 

The platform also features its virtual machine, the Arbitrum Virtue Machine (AVM). The AVM is an execution area for Arbitrum smart contract and it is located on top of EthBridge. EthBridge is a smart contract collection that interacts directly with the Arbitrum chain. The AVM automatically converts Ethereum-compatible smart contracts to run on it. 


Advantages of Arbitrum 

This project is intended to make it easy for developers to create highly efficient and scalable Ethereum-compatible smart contracts. 

It’s not the only platform trying to overcome Ethereum’s limitations. There are at least 12 other solutions that offer similar functionality. What is the difference between Arbitrum and the rest? It has many distinguishing characteristics, including: 

Low Gas Fee 

Arbitrum, a layer 2 scaling solution, is not only designed to increase Ethereum’s transaction throughput but also to reduce transaction fees. 

Arbitrum’s highly efficient roll-up technology allows it to reduce fees to a fraction of Ethereum while still offering validators enough incentives. 

High EVM compatibility 

Arbitrum is one of the most compatible rollups with EVM. It is compatible with the EVM at the bytecode level and can be compiled to EVM out of the box by any language, such as Solidity or Vyper. 

It is easy to develop on Arbitrum, as developers don’t need to learn a new language to build on it. 

Developer Friendly 

Arbitrum’s team is doing everything they can to reduce barriers to entry for those who want to build on their layer 2. They have created extensive documentation for Arbitrum developers so that they can help them get started with existing tools for Ethereum. You don’t need to download any specific tools for Arbitrum such as plugins or compilers such as Hardhat and Truffle. 

A good ecosystem 

Arbitrum has already been involved in a variety of Ethereum DApps, infrastructure projects, and such things as UniSwap and SushiSwap. 

How to Use Arbitrum 

Arbitrum can be used through decentralized applications like Aave or Gnosis Safe. You also have the option to use Arbitrum’s token bridge. After you have connected your MetaMask wallet, you can deposit funds into the Arbitrum network. Clearing deposits takes approximately 10 minutes.
