The cross-chain BSN protocol is expected to complete the design and internal beta by mid-2021.

On November 27, at the 1st World Summit on Innovation and Technology Development Blockchain Service Network (BSN), He Yifan, CEO of Beijing Jujube Technology, said that the current channel cut is divided into four types. Cross chain (centralized exchange), Layer 2 cross chain (Cosmos, Polkadot heterogeneous chain), Layer 1 cross chain (IBC, Polkadot Parachain, MAP), Layer 0 cross chain. Layer 0 cross chain is a Layer structure similar to HTTP, which is the core language of BSN. BSN's system-level cross-chain protocol plans to complete its design and internal beta by mid-2021.
