Changpeng Zhao’s multi-chain vision is taking shape as BNB Chain prepares a new Layer 1 blockchain while ASTER, backed by CZ’s investment firm YZi Labs, continues to develop its own trading-focused network.
CZ addressed the strategy in a post on X, stating, “Multiple chains, one coins,” in response to the BNB Chain proposal. The remark reflects an approach that allows multiple blockchains to serve different purposes while potentially relying on a shared native asset rather than introducing a separate token for each network.
The proposal raises an important question about CZ’s broader ecosystem strategy: can specialized blockchains target different use cases while contributing to the growth of a connected network of applications, projects, and digital assets?
BNB Chain’s proposed Layer 1 is intended to operate alongside BNB Smart Chain (BSC), rather than replace the existing network. Official technical documentation outlines plans for a high-performance blockchain designed for applications where speed is critical, including high-frequency trading, on-chain order books, and real-time payments.
The network’s development targets include 200-millisecond block times, transaction pre-confirmations within 20 milliseconds, and finality in less than one second. These specifications are still targets rather than confirmed performance benchmarks. A public testnet is planned for late 2026, followed by a potential mainnet launch in early 2027.
One of the proposal’s defining features is its planned token structure. BNB is expected to serve as the native asset for transaction fees and staking, extending its role across multiple networks without requiring the introduction of another cryptocurrency.
CZ’s comment about multiple chains sharing one coin captures the underlying idea. Rather than building every blockchain as an isolated ecosystem, BNB Chain could support specialized networks linked through a common token and interoperability infrastructure.
This could broaden the utility of BNB while allowing different applications to operate on infrastructure tailored to their technical requirements.
ASTER Highlights a Different Approach to Blockchain Expansion
ASTER offers a useful comparison because its dedicated Layer 1 blockchain is already operational. Aster Chain launched its mainnet on March 17, 2026, positioning itself as a privacy-oriented network built specifically for on-chain trading.
Its infrastructure emphasizes encrypted order flow, transaction privacy, and execution efficiency, with a particular focus on derivatives traders who want to limit public visibility into their trading activity.
Aster’s launch announcement states that the network targets throughput of more than 100,000 transactions per second, with median block times of 50 milliseconds.
The project is backed by YZi Labs, the investment firm formerly known as Binance Labs. CZ remains involved in YZi Labs’ investment activities, although the firm’s backing does not establish that he directly manages or controls every portfolio project.
The distinction between the two networks lies in their intended scope. BNB’s proposed Layer 1 is designed to support a broader selection of applications, spanning trading, payments, and privacy-related services. Aster Chain concentrates more specifically on trading infrastructure, including features intended to protect order details and traders’ positions from public exposure.
Although both projects favor specialized blockchain infrastructure, their objectives are not identical. BNB Chain is pursuing a broader high-performance environment, while ASTER is targeting the specific requirements of on-chain markets.
Can Multiple Layer 1 Networks Expand the BNB Ecosystem?
The emergence of BNB’s proposed Layer 1 alongside ASTER raises a wider question about the future of blockchain ecosystems: must one network dominate, or can several specialized chains coexist and serve different audiences?
A shared BNB token could help maintain continuity as BNB Chain expands its infrastructure. Developers and users accessing additional networks might not need to adopt a new native asset for every blockchain, potentially reducing friction across the ecosystem.
Meanwhile, projects such as ASTER can differentiate themselves by building products around specific market demands, including derivatives trading, transaction privacy, and faster execution. This specialization could expand the range of services available to users across the crypto industry.
However, a multi-chain structure also introduces potential drawbacks. Liquidity, developer resources, and user activity may become fragmented across several networks, particularly when their applications compete for the same audience.
There is also no guarantee that using BNB across additional blockchains will automatically increase demand for the token. The impact will depend on actual network adoption, application growth, and whether transaction fees, staking, and other activities generate sustained demand for BNB.
Ultimately, the success of CZ’s multi-chain strategy will depend on whether these specialized networks can attract meaningful activity while remaining sufficiently connected to strengthen the wider ecosystem.
