Arbitrum has emerged as a leading Ethereum scaling solution, garnering significant attention even before its airdrop in March 2023. Its utility as a layer-two scaling solution for the Ethereum network has been pivotal in establishing its prominence within the broader cryptocurrency ecosystem.

What is Arbitrum?

Arbitrum is a Layer 2 blockchain protocol specifically developed to enhance the scalability of the Ethereum network. Arbitrum aims to increase transaction throughput on Ethereum by employing optimistic roll-ups while maintaining its security and decentralization. It provides a seamless migration path for developers to transition their applications from the Layer 1 Ethereum protocol to the Layer 2 Arbitrum protocol.

Offchain Labs created the protocol, and its Mainnet was launched in 2021. In March 2023, the Arbitrum Foundation introduced ARB as the native token of the Arbitrum ecosystem. This marked an important milestone in the project's evolution and further solidified its role in the crypto space.

The Arbitrum team

The Arbitrum team comprises Ed Felten, Steven Goldfeder, and Harry Kalodner, previously researchers at Princeton University. Ed Felten, a Professor of Computer Science, brings his expertise to the project, while Steven Goldfeder and Harry Kalodner hold Ph.D. degrees in Computer Science. Together, they form a skilled and knowledgeable team driving the development and innovation behind Arbitrum.

How does Arbitrum work?

The Arbitrum network utilizes optimistic roll-ups to scale the Ethereum network. While the Ethereum blockchain can handle only 15-30 transactions per second (TPS), roll-ups can increase transaction speed by up to 85 times.

Optimistic roll-ups aggregate transactions and process them off-chain in batches rather than individually on-chain. These transactions are then verified in batches and with reduced frequency on the blockchain.

To illustrate, think of optimistic roll-ups as grouping multiple transactions, similar to picking up all the items you need from a supermarket in one go rather than paying for each item separately.

In contrast, the traditional Ethereum network processes transactions one by one, like paying for each item individually at the store. Arbitrum's protocol, leveraging optimistic roll-ups, enables transactions to be rolled-up and processed in batches, thus enhancing scalability and efficiency.

Arbitrum’s native token: ARB

ARB is an ERC-20 token that functions as the governance token within the Arbitrum ecosystem. ARB Holders can vote on proposals put forth in the decentralized autonomous organization (DAO), either in favor or against them.

Tokenomics

ARB has a total supply of 10 billion tokens, with a circulating supply of 1.275 billion tokens. During the viral airdrop on March 23, 2023, the Arbitrum Foundation distributed 12.75% of the total ARB supply to users and DAOs.

Staking ARB tokens

ARB tokens can be staked on various decentralized exchanges (DEXs), allowing users to earn rewards from the fees generated by the liquidity pool. The longer the ARB tokens are staked or locked, the higher the potential rewards for the user.

Additionally, centralized exchanges (CEXs) like OKX provide staking services for ARB through their OKX Earn. Users can earn a flexible 1 percent annual percentage yield (APY) on their staked ARB tokens.

Arbitrum’s use cases

Arbitrum's use cases primarily revolve around its governance functionality. As the native governance token of the ecosystem, ARB is designed for voting on proposals and decisions within the Arbitrum network. Additionally, ARB can be staked to earn rewards and serve as a store of value for users within the ecosystem. It's important to note that ARB is not utilized as gas fees for transactions on the network

ARB Token distribution

The supply distribution of ARB is as follows:

  • Arbitrum DAO treasury: 42.78%
  • Offchain Labs teams and advisors: 26.94%
  • Investors: 17.53%
  • Airdrop to users: 11.62%
  • Airdrop to DAOs: 1.13%

Arbitrum’s future vision

Arbitrum's future vision is centered around achieving progressive decentralization. While the Arbitrum Foundation currently holds most of the decision-making power in the ecosystem, the goal is to transition towards a more decentralized governance model as the Arbitrum ecosystem expands and more web3 users engage with the network.

In the meantime, ARB token holders can actively participate in voting for improvement proposals, ensuring a level of community involvement.

Furthermore, Arbitrum has plans to launch a Layer 3 DApp shortly.

This layer-three solution, called Orbit, will allow developers to deploy programs using popular programming languages such as Rust and C++.

Consensus Mechanism
Arbitrum is present on the following networks: arbitrum, ethereum. Arbitrum is a Layer 2 solution on top of Ethereum that uses Optimistic Rollups to enhance scalability and reduce transaction costs. It assumes that transactions are valid by default and only verifies them if there's a challenge (optimistic): Core Components: • Sequencer: Orders transactions and creates batches for processing. • Bridge: Facilitates asset transfers between Arbitrum and Ethereum. • Fraud Proofs: Protect against invalid transactions through an interactive verification process. Verification Process: 1. Transaction Submission: Users submit transactions to the Arbitrum Sequencer, which orders and batches them. 2. State Commitment: These batches are submitted to Ethereum with a state commitment. 3. Challenge Period: Validators have a specific period to challenge the state if they suspect fraud. 4. Dispute Resolution: If a challenge occurs, the dispute is resolved through an iterative process to identify the fraudulent transaction. The final operation is executed on Ethereum to determine the correct state. 5. Rollback and Penalties: If fraud is proven, the state is rolled back, and the dishonest party is penalized. Security and Efficiency: The combination of the Sequencer, bridge, and interactive fraud proofs ensures that the system remains secure and efficient. By minimizing on-chain data and leveraging off-chain computations, Arbitrum can provide high throughput and low fees. The Ethereum network uses a Proof-of-Stake Consensus Mechanism to validate new transactions on the blockchain. Core Components 1. Validators: Validators are responsible for proposing and validating new blocks. To become a validator, a user must deposit (stake) 32 ETH into a smart contract. This stake acts as collateral and can be slashed if the validator behaves dishonestly. 2. Beacon Chain: The Beacon Chain is the backbone of Ethereum 2.0. It coordinates the network of validators and manages the consensus protocol. It is responsible for creating new blocks, organizing validators into committees, and implementing the finality of blocks. Consensus Process 1. Block Proposal: Validators are chosen randomly to propose new blocks. This selection is based on a weighted random function (WRF), where the weight is determined by the amount of ETH staked. 2. Attestation: Validators not proposing a block participate in attestation. They attest to the validity of the proposed block by voting for it. Attestations are then aggregated to form a single proof of the block’s validity. 3. Committees: Validators are organized into committees to streamline the validation process. Each committee is responsible for validating blocks within a specific shard or the Beacon Chain itself. This ensures decentralization and security, as a smaller group of validators can quickly reach consensus. 4. Finality: Ethereum 2.0 uses a mechanism called Casper FFG (Friendly Finality Gadget) to achieve finality. Finality means that a block and its transactions are considered irreversible and confirmed. Validators vote on the finality of blocks, and once a supermajority is reached, the block is finalized. 5. Incentives and Penalties: Validators earn rewards for participating in the network, including proposing blocks and attesting to their validity. Conversely, validators can be penalized (slashed) for malicious behavior, such as double-signing or being offline for extended periods. This ensures honest participation and network security.
Incentive Mechanisms and Applicable Fees
Arbitrum is present on the following networks: arbitrum, ethereum. Arbitrum One, a Layer 2 scaling solution for Ethereum, employs several incentive mechanisms to ensure the security and integrity of transactions on its network. The key mechanisms include: 1. Validators and Sequencers: o Sequencers are responsible for ordering transactions and creating batches that are processed off-chain. They play a critical role in maintaining the efficiency and throughput of the network. o Validators monitor the sequencers' actions and ensure that transactions are processed correctly. Validators verify the state transitions and ensure that no invalid transactions are included in the batches. 2. Fraud Proofs: o Assumption of Validity: Transactions processed off-chain are assumed to be valid. This allows for quick transaction finality and high throughput. o Challenge Period: There is a predefined period during which anyone can challenge the validity of a transaction by submitting a fraud proof. This mechanism acts as a deterrent against malicious behavior. o Dispute Resolution: If a challenge is raised, an interactive verification process is initiated to pinpoint the exact step where fraud occurred. If the challenge is valid, the fraudulent transaction is reverted, and the dishonest actor is penalized. 3. Economic Incentives: o Rewards for Honest Behavior: Participants in the network, such as validators and sequencers, are incentivized through rewards for performing their duties honestly and efficiently. These rewards come from transaction fees and potentially other protocol incentives. o Penalties for Malicious Behavior: Participants who engage in dishonest behavior or submit invalid transactions are penalized. This can include slashing of staked tokens or other forms of economic penalties, which serve to discourage malicious actions. Fees on the Arbitrum One Blockchain 1. Transaction Fees: o Layer 2 Fees: Users pay fees for transactions processed on the Layer 2 network. These fees are typically lower than Ethereum mainnet fees due to the reduced computational load on the main chain. o Arbitrum Transaction Fee: A fee is charged for each transaction processed by the sequencer. This fee covers the cost of processing the transaction and ensuring its inclusion in a batch. 2. L1 Data Fees: o Posting Batches to Ethereum: Periodically, the state updates from the Layer 2 transactions are posted to the Ethereum mainnet as calldata. This involves a fee, known as the L1 data fee, which accounts for the gas required to publish these state updates on Ethereum. o Cost Sharing: Because transactions are batched, the fixed costs of posting state updates to Ethereum are spread across multiple transactions, making it more cost-effective for users. Ethereum, particularly after transitioning to Ethereum 2.0 (Eth2), employs a Proof-of-Stake (PoS) consensus mechanism to secure its network. The incentives for validators and the fee structures play crucial roles in maintaining the security and efficiency of the blockchain. Incentive Mechanisms 1. Staking Rewards: Validator Rewards: Validators are essential to the PoS mechanism. They are responsible for proposing and validating new blocks. To participate, they must stake a minimum of 32 ETH. In return, they earn rewards for their contributions, which are paid out in ETH. These rewards are a combination of newly minted ETH and transaction fees from the blocks they validate. Reward Rate: The reward rate for validators is dynamic and depends on the total amount of ETH staked in the network. The more ETH staked, the lower the individual reward rate, and vice versa. This is designed to balance the network's security and the incentive to participate. 2. Transaction Fees: Base Fee: After the implementation of Ethereum Improvement Proposal (EIP) 1559, the transaction fee model changed to include a base fee that is burned (i.e., removed from circulation). This base fee adjusts dynamically based on network demand, aiming to stabilize transaction fees and reduce volatility. Priority Fee (Tip): Users can also include a priority fee (tip) to incentivize validators to include their transactions more quickly. This fee goes directly to the validators, providing them with an additional incentive to process transactions efficiently. 3. Penalties for Malicious Behavior: Slashing: Validators face penalties (slashing) if they engage in malicious behavior, such as double-signing or validating incorrect information. Slashing results in the loss of a portion of their staked ETH, discouraging bad actors and ensuring that validators act in the network's best interest. Inactivity Penalties: Validators also face penalties for prolonged inactivity. This ensures that validators remain active and engaged in maintaining the network's security and operation. Fees Applicable on the Ethereum Blockchain 1. Gas Fees: Calculation: Gas fees are calculated based on the computational complexity of transactions and smart contract executions. Each operation on the Ethereum Virtual Machine (EVM) has an associated gas cost. Dynamic Adjustment: The base fee introduced by EIP-1559 dynamically adjusts according to network congestion. When demand for block space is high, the base fee increases, and when demand is low, it decreases. 2. Smart Contract Fees: Deployment and Interaction: Deploying a smart contract on Ethereum involves paying gas fees proportional to the contract's complexity and size. Interacting with deployed smart contracts (e.g., executing functions, transferring tokens) also incurs gas fees. Optimizations: Developers are incentivized to optimize their smart contracts to minimize gas usage, making transactions more cost-effective for users. 3. Asset Transfer Fees: Token Transfers: Transferring ERC-20 or other token standards involves gas fees. These fees vary based on the token's contract implementation and the current network demand.
