What is opBNB

At its core, opBNB serves as a layer 2 solution integrated with Binance Chain (formerly Binance Smart Chain), offering users newfound control over their data assets within the Binance ecosystem.

Unlike other platforms, the chain doesn’t introduce a new native token; instead, it utilizes BNB itself.

This approach ensures that BNB remains the main utility token, functioning both as a gas token and a governance token on the platform.

opBNB Faucet

Faucets are often used in Blockchain and cryptocurrency communities as a way to distribute tokens to users for testing and experimentation purposes on testnets.

These test tokens have no real-world value and are intended solely for testing within a Blockchain network.

In this case, there is no dedicated faucet for the chain, instead, users need to follow the steps below.

  1. Get tBNB on Binance Chain: Users typically need to visit the BNB faucet website (, complete any required captcha or verification process, and provide their testnet address (where they want the test tokens to be sent).
  2. Bridge tBNB to opBNB: Once received the test token (tBNB), users can start bridging tBNB to opBNB chain via the testnet bridge at

opBNB Explorer

An opBNB Explorer, in the context of this layer 2, is a web-based tool or service that allows users to explore and view various information related to transactions, blocks, addresses, and other data on the Blockchain.

opBNB Bridge

The opBNB Bridge is a crucial component within the ecosystem that facilitates the seamless transfer of assets and data between the opBNB Blockchain and the Binance Chain (BSC).

This bridge acts as a conduit for cross-chain interoperability, allowing users to move assets and data between these two Blockchain networks efficiently.

How it Works

Integration with Binance Chain (BSC)

This layer 2 operates within the broader Binance Chain ecosystem, intricately linked to Binance Chain itself.

This integration ensures that data permissions and management logic are directly connected to BSC.

In essence, opBNB harmonizes data ownership with the decentralized finance (DeFi) landscape of BSC, allowing users to interact with their data assets seamlessly across both platforms.


Storage Providers (SPs)

Central to the network’s operation is its network of “storage providers” (SPs).

These entities, whether individuals or organizations, offer storage services on the platform.

SPs play a critical role in responding to user requests for uploading and downloading data.

They also function as gatekeepers, overseeing user rights and authentications, thereby ensuring data remains secure and readily accessible.


Cross-Chain Bridge

Facilitating the seamless transfer of assets and data between opBNB and BSC is a native cross-chain bridge.

This bridge empowers users to transfer assets, including BNB, between the two chains with ease.

This interoperability ensures that users can make the most of their assets and data across both platforms.

Consensus Mechanism

This layer 2 employs a unique consensus mechanism that combines elements of Delegated Proof of Stake (DPoS) and Proof of Authority (PoA).

In this system, validators take turns producing blocks, much like Ethereum’s Clique consensus design.

The validator set is determined through a staking-based governance process, promoting decentralization and community governance.

This hybrid consensus mechanism ensures efficient transaction processing and faster block production.


Fast Finality

In the realm of Blockchain, finality is of paramount importance.

The chain is poised to deliver fast finality, a feature that instills confidence in the accuracy of the latest finalized block.

Fast finality empowers users to make swift, informed decisions, ultimately enhancing the overall user experience.



What are its Advantages

Decentralized Data Management

A standout advantage of this Layer 2 lies in its commitment to decentralized data management.

Users enjoy unparalleled control over their data assets, including the ability to grant access, modify permissions, create, delete, and execute data-related functions.

This degree of autonomy empowers individuals and organizations to tailor their data management to their precise needs.


Data Assetization

The chain introduces a groundbreaking concept: data assetization.

All data and access permissions within the platform can be represented as Non-Fungible Token (NFT) assets on the Binance Smart Chain network.

These assets are fully tradable and interactable on BSC, facilitating the flow of data value across a plethora of decentralized applications (dApps) and opening up new avenues for data monetization.


Programmable Data Ownership

The platform offers users the freedom to program their data ownership rules.

This customization ensures that data management aligns precisely with individual requirements, providing a tailored experience for each user.


Seamless User Experience

This network strives to provide a user experience that rivals that of state-of-the-art cloud storage services while maintaining cost-efficiency.

Users can interact with the platform using their Blockchain addresses as identifiers, seamlessly connecting with features and smart contracts on both opBNB and BSC.

This streamlined experience simplifies user onboarding and enhances accessibility.


What is the Greenfield Blockchain?

To fully grasp its role in the BSC ecosystem, it’s imperative to understand its connection to the Greenfield Blockchain. The Greenfield Blockchain serves as the foundational infrastructure for the opBNB platform, offering the core support needed for its operation.

Decentralized Storage of Data

Greenfield Blockchain plays a pivotal role in the Greenfield ecosystem by facilitating decentralized data storage.

Any individual or organization can register as a storage provider, and Greenfield records the distribution of data across multiple storage providers.

This approach guarantees data redundancy and availability.


Data Ownership

Greenfield empowers users with comprehensive data ownership management functions.

Users can exercise control over their data assets, including granting access, modifying permissions, and defining data ownership rules.

Greenfield’s commitment to data ownership aligns perfectly with its objectives.


Data Assetization on BSC

A significant aspect of Greenfield’s ecosystem is its ability to represent data and access permissions as NFT assets on the Binance Smart Chain.

These assets are fully tradable and interactable on BSC, promoting the flow of data value across the broader Blockchain landscape.


Validator Role

Validators within the Greenfield Blockchain ecosystem play a pivotal role in maintaining the network’s security and reliability.

They are responsible for achieving consensus on cross-chain events, relaying cross-chain packets, and ensuring the integrity of data provided by storage providers.

Validators also actively participate in governance, voting on issues related to the platform’s development, and adjusting network parameters as necessary.
