After months of development and testing by more than 400,000 user wallets on Testnet and completing the final testing steps, now Binance's Layer 2 project opBNB launches its Mainnet. So what does opBNB currently have? Let's find out below.
1. opBNB là gì?
opBNB is a Layer 2 project of the BNB chain that integrates OP Stack technology of Optimism. BNB's Layer 2 is built to aim at creating a better blockchain environment for developers of games and Web3-related products.
Integrating OP Stack technology allows opBNB to better expand the BNB chain's network while still inheriting the security features of the main network.
In addition, opBNB also has good EVM compatibility and each block only accounts for more than 4k TPS with extremely cheap transaction fees (~$0.005). This will create an ideal environment for game projects that require fast and continuous transaction processing.
2. What are the benefits of opBNB using OP Stack?
OP Stack is a complete SDK toolkit that allows projects/organizations when building their own Layer 2 to easily build without having to build from scratch.
With the advantages of OP Stack, opBNB will have advantages such as:
Allows flexible customization of execution client: This customization ability allows opBNB to execute smart contracts with different clients and increase the decentralization of the platform. From there, it helps increase decentralization and network performance.
Data Availability (DA) layer replaceability: opBNB can switch between different DA schemes based on performance and security needs, thereby allowing nodes to select the necessary data that they need. No need to select all. Additionally, opBNB can leverage BNB greenfield as the DA layer, which will further reduce costs.
Open ecosystem: opBNB can join networks that share the same technology and interact with each other. For example, opBNB can connect to Optimism, or other OP-Chains which are other Layer 2s based on OP Stack supporting EVM and Solidity. By becoming part of the ecosystem, opBNB can increase network efficiency and security.
3. Structure of opBNB
The structure of opBNB includes three main parts: Sequencer, Prover and Verifier with main functions such as:
Prover (Node): Is the part that provides evidence to verify that transactions are valid. Prover's main goal is to ensure accuracy and reliability from transactions while being free of third-party intrusion.
Verifier (Challenger): Is the part that checks evidence from Prover and ensures that transactions on opBNB are valid and not fraudulent.
Sequencer: Is the place to calculate and convert the state of transactions. After that, the Sequencer will send the information of the transactions to the roll up contract (Roll up contract is responsible for processing and confirming transactions on Layer 2) and then transfer the transaction information to the BNB Chain.
The operating method of opBNB will be sequential as follows:
B1: User makes a transaction on opBNB.
B2: After receiving information, transactions are authenticated and associated evidence is created by the Prover (node).
Step 3: Once authenticated and there is evidence, Sequencer will receive, synthesize and send transactions back to BNB Chain.
If during the Sequencer process of synthesizing transactions and detecting errors, they will send these transactions to Verifier for confirmation again. Finally, Verifier will send proof of violation or non-violation to BNB Chain.
4. What are opBNB's strengths?
By using OP Stack technology, opBNB will inherit the outstanding features of this technology such as:
High interoperability: Using OP Stack means that opBNB participates in the OP-chain ecosystem, allowing opBNB to interact with other Layer 2s that integrate with other OP Stack such as: Base, Zora Network, Celo, WorldCoin, Debank, Public Goods Network,…
EVM compatible: opBNB allows developers to easily build dApps on the opBNB ecosystem.
Low transaction fees: opBNB is developed on BNB Chain with low transaction fees (~ 1 USD/transaction). Therefore, opBNB offers users low transaction fees averaging 0.005 USD/transaction.
Expanding the Binance ecosystem: opBNB is highly interoperable with BNB Greenfield, BNB Chain, BNB Beacon Chain, and zkBNB. Thus allowing Binance to expand its ecosystem larger and larger.
5. OpBNB promotion program
In order to attract more developers as well as promote its Layer 2 network, Binance has launched its Hackathon program.
The program will last from July 13 to September 1, 2023 with prizes for each project up to $10k, details as follows:
In addition to rewards for projects, there are other additional rewards:
In addition to the above rewards, developers will enjoy accompanying privileges such as:
1 month of testing participation in the BNB Chain Gas Grant program.
Promotional support package from BNB Chain.
Get great discounts on tools and services from the BNB Chain Kickstart program.
$2000 credit and $5000 POC trial coupon from Google Cloud and Alibaba Cloud.
RPC/API: 3-month enterprise plan worth $3000 from NodeReal.
Developers can participate register for the Hackathon right here. Currently, the program is still in progress, so this will be a good opportunity for those who are project developers to participate and have the opportunity to receive rewards as well as participate in the ecosystem. Binance.
The program has cooperation with other partners such as: Google Cloud, AWS, Alibaba Cloud, Hooked Protocol, Cyberconnect, Combo, Ultiverse.
In addition to the program for developers, opBNB also launches a program for the community, to attract users to opBNB. The show is called: THE ODYSSEY FROM TESTNET TO MAINNET
This is a program for all communities participating in opBNB's ecosystem, lasting for a period of 15 days from August 10 to August 25, 2023.
Program details will follow 3 steps:
Step 1: Complete 3 basic missions on Galxe here.
Step 2: Complete various tasks to earn more Points
Step 3: Receive rewards after mainnet launch
You can follow the show's POINT rankings here.
6. Conclusion
opBNB is a new Layer 2 developed by Binance using OP Stack technology, this is a network with the goal of building an ecosystem for gaming and social projects. Integrating OP Stack allows opBNB's network to interoperate with Layer 2 ecosystems with the same technology in OP Stack, which enhances greater scalability for this ecosystem.
Not only that, with the low cost of the network, this will be a potential Layer 2 ecosystem for developers who can easily build game projects and create a better gaming environment for their users. me.
Currently, opBNB is quite new and is in the final stages of testing before the official mainnet launch. If you are interested, you can participate in this ecosystem and receive rewards from the project's programs.
However, new ecosystems will always have the potential for many scam and hacker projects, so you need to pay careful attention to avoid losing money.
