BSC welcomes a major update, BNB Chain multi-chain ecosystem officially launched

In the wave of blockchain infrastructure development, the BNB ecosystem has driven an important technological integration. The former Binance Chain (BC) and Binance Smart Chain (BSC) officially merged in early 2022 to form a unified EVM-compatible multi-chain system, adopting a new brand identity—BNB Chain. This upgrade is not only a name change but also represents the technological evolution and strategic shift of the entire ecosystem.

From Two Separate Chains to a Unified Ecosystem—BNB Chain’s Technical Architecture Upgrade

In the original design, Binance Chain was mainly responsible for governance functions (staking and voting), while BSC handled smart contracts and application layers. Although this division of labor served its purpose, as the ecosystem expanded, the need for integration between the two chains became increasingly urgent.

The new BNB Chain architecture unifies these two chains: BNB Beacon Chain (the original Binance Chain) continues to oversee governance, while BNB Smart Chain (the original BSC) serves as the core EVM-compatible execution layer and multi-chain hub. This design reinforces the central role of the governance token BNB and also reflects the ecosystem’s move towards decentralization—BNB’s utility has gone beyond a single exchange scope, truly becoming the foundational token of the entire ecosystem, carrying the mission of “Build and Build.”

Data Support Behind Scale Expansion—Verification Nodes Doubling

The most direct reflection of the ecosystem upgrade’s success is in network scale. Before this upgrade, BSC had 21 validator nodes; after the upgrade, the number increased to 41 (including 20 candidate block-producing nodes). The doubling of validator nodes not only signifies a numerical increase but also greatly enhances the network’s decentralization, overall consensus security, and throughput capacity.

The official team has also simultaneously promoted multiple technical optimizations, allowing community users, project developers, and ecosystem participants to experience a more stable and efficient infrastructure. Despite these changes, BNB Chain maintains its core characteristics of being community-driven, open-source, and decentralized—this is the source of its long-term competitiveness.

MetaFi New Concept, BNB Chain’s Path Toward the Metaverse Economy Era

Ecology coordinator Samy Karim revealed that after the upgrade, BNB Chain will actively embrace large-scale applications such as GameFi, SocialFi, and the Metaverse. The strategic vision behind this is a broader concept—MetaFi.

MetaFi integrates multiple dimensions including the Metaverse, DeFi, GameFi, SocialFi, Web3, and NFTs, depicting a parallel economic system built on standardized metadata and universal digital assets. Based on this concept, BNB Chain is constructing the economic infrastructure of virtual worlds, integrating different blockchain projects to create an economic ecosystem serving the Metaverse era for global users. In short, BNB Chain’s goal is no longer just to provide infrastructure but to become a key hub connecting the real and virtual economies.

From the integration of two chains to a multi-chain ecosystem, and now to the MetaFi vision, BNB Chain is using technological innovation and ecosystem expansion to define the future of blockchain infrastructure.
