The BNB Chain Beacon Chain Migration Guidance

---

The BNB Beacon Chain, initially designed as a staking and governance layer, serves to complement BNB Smart Chain (BSC) by enhancing security and supporting decentralized exchanges (DEXs). However, with the evolution of BSC and changes in the blockchain landscape, including the decommissioning of order-book-based DEXs in BEP151, the BNB Beacon Chain has become increasingly redundant. Its connection to BSC through a cross-chain bridge has introduced development complexities and security vulnerabilities.

 

As a result, the BNB Chain Fusion is a strategic shift to migrate the BNB Beacon Chain’s functionalities to BNB Smart Chain (BSC) and retire BNB Beacon Chain. This move aims to streamline the network, improve efficiency, reduce security risks, and align BNB Chain's architecture with the current technological demands and future growth.
