What isArbitrum ?
Presentation ofArbitrum
Arbitrum Layer 2 scalability solution which aims to increase the processing capacity of transactions on Ethereum . Its principle is based on the technique of optimistic rollups , where transactions are grouped out of chain before being submitted in lot (or "batch") to the Ethereum . This makes it possible to unload a large part of the validation work of Ethereum , making transactions less expensive and faster.
The advantages ofArbitrum for Ethereum
Arbitrum has several advantages forEthereum users:
- Reduction of gas costs : by reducing the load on the main channel, Arbitrum makes it possible to minimize the transaction costs.
- Increased speed : Thanks to out -of -chain treatment, Arbitrum can treat a larger volume of transactions simultaneously.
- Total compatibility with Ethereum : Arbitrum uses the virtual machine of Ethereum (EVM), which means that the smart contract written for Ethereum can be deployed without modification on Arbitrum .
Why does Ethereum needArbitrum ?
Ethereum 's current limits
Ethereum , due to its popularity, faces regular congestion. This leads to high transaction costs and prolonged waiting times. Currently, Ethereum can only treat 20 to 40 transactions per second , which is insufficient in the face of growing demand.
How does Arbitrum improve scalability?
Arbitrum allows Ethereum to increase its treatment capacity by outsourcing part of the calculations outside the main channel. By bringing together transactions in compressed lots, then validating them in a single interaction on Ethereum , Arbitrum considerably lightens the main network load while ensuring security thanks to a mechanism of evidence of fraud .
The operation ofArbitrum
How does it optimize Ethereum transactions?
Using transaction batches Arbitrum makes it possible to submit hundreds of transactions in a single interaction with Ethereum , thereby minimizing gas costs. In addition, the data is compressed, which further reduces the cost of use of the network.
The mechanism of optimistic rollups
Optimistic Rollups operate on the basis of minimum confidence. Transactions are considered valid until no evidence of fraud is subject. If a transaction is suspect, a validator can initiate a dispute, and the Ethereum will contrast the validity of the transaction.
The roles of the validators in Arbitrum
Validators are essential players in the network. They submit lots of transactions to Ethereum and can challenge suspicious transactions. To do this, they must bring into play the funds that will be lost if they act maliciously. Their role guarantees the integrity of the network.
Arbitrum Rollup vs. Arbitrum Anytrust
The differences between Rollup and Anytrust
Arbitrum offers two solutions: Arbitrum Rollup and Arbitrum Anytrust . The main difference lies in the way the data is managed. In a Rollup , all transaction data is subject to Ethereum , thus ensuring maximum decentralization. In Anytrust , the data is stored by a data committee , which reduces the costs but introduces partial confidence towards this committee.
What is a data committee and how does it work?
A data committee is a group of stakeholders responsible for storing data from transactions out of chain in the Anytrust model. As long as two committee members are honest, the data can be recovered if necessary. This model makes it possible to reduce costs by not systematically subjecting data to Ethereum , but it is considered slightly less decentralized than Rollup.
What uses for each technology?
Rollup is ideal for applications requiring maximum security, such as decentralized financial applications ( DEFI ). On the other hand, Anytrust is more suitable for applications requiring a high cost volume of transactions at low cost, such as decentralized games or social networks.
The costs and speed of transactions on Arbitrum
Why are transactions cheaper?
Arbitrum transactions are less expensive thanks to the use of batches and data compression . By bringing together several transactions in a single batch, Arbitrum reduces the number of interactions with the Ethereum , which reduces gas costs.
Batching and data compression
Data compression reduces the size of the information submitted to Ethereum , which decreases the overall cost of transactions. However, this also implies that certain data must be processed out of chain, increasing the need for solid safety mechanisms to guarantee the integrity of transactions.
Security and decentralization in Arbitrum
What are the risks of out -of -chain transactions?
One of the main risks of outside chain transactions is the potential for centralization and loss of data control. In a model like Anytrust , security is based on the good behavior of a data committee , which introduces a level of confidence. If a majority of the members of this committee act maliciously, there is a risk of data handling.
How does Arbitrum guarantee user safety?
Arbitrum uses a system of evidence that allows any validator to challenge a suspicious transaction. This mechanism guarantees that in the event of fraud, malicious actors can be detected and sanctioned, thus protecting users.
The transactions contestation system
How does evidence work?
When a validator suspects fraud, he can initiate a dispute on the Ethereum . This challenge takes place in the form of a "game", where the parties involved gradually refine their disagreement to a specific point of the execution of the transaction. If fraud is proven, the malicious validator loses the funds he had put into play.
The role of the various actors in the dispute of transactions
The main players in the protest system are validators , users , and Ethereum chain itself. The validators check the transactions and initiate disputes if necessary.
Users benefit from the reinforced security offered by this mechanism. Finally, the Ethereum chain plays the role of final referee in the resolution of arguments.
Development of smart contractS on Arbitrum
The tools available for developers
Developers can use tools like Hardhat or Truffle to deploy smart contract S on Arbitrum . Thanks to compatibility with the EVM, the contracts developed for Ethereum can be deployed without modification on Arbitrum .
Deploy a contract on Arbitrum
The deployment process is similar to that on Ethereum . Developers can use languages like Solide to create their contracts, and the deployment is made faster and less expensive thanks to the optimizations of Arbitrum .
The future ofArbitrum : new developments
The new features on which the team works
Arbitrum team is currently working on several improvements, including optimization of data processing to further reduce costs and increase the speed of transactions. In addition, compatibility features with other programming languages such as Rust are being developed via Stylus .
Arbitrum nova and Arbitrum one: major differences
Arbitrum One Rollup technology , while Arbitrum Nova Anytrust technology to provide low-cost ultra-rapid transactions. Nova is particularly suitable for applications requiring a high volume of transactions, such as games or social networks.
How to become a validator on Arbitrum
Role and responsibilities of a validator
Validators play a crucial role in maintaining the security of the Arbitrumnetwork. They submit transactions to Ethereum and initiate disputes in the event of fraud.
The resources necessary to become a validator
To become a validator, it is recommended to have at least 16 GB of RAM , a powerful processor (4 or more cores), and enough storage to manage the chain. Validators must also be ready to focus funds to participate in the validation process.
Arbitrum 's current challenges
The challenges of long -term scalability
While Arbitrum improves the scalability of Ethereum , there are still challenges to be met, in particular the management of the continuous increase in the volume of transactions and the improvement of the efficiency of optimistic rollups .
Governance issues in Arbitrum
Arbitrum 's governance is now largely decentralized thanks to the token $ arb . However, the participation of the community and the balance between decentralization and efficiency remain subjects of debate.
Conclusion
Arbitrum is positioned as a powerful solution to improve the scalability ofEthereum while maintaining security and decentralization. Thanks to its innovations, Arbitrum makes it possible to treat more transactions at a lower cost, while providing developers and users an optimized experience.
