Project Background and Challenges

The client is an ecosystem operations team that needs a proprietary EVM-compatible mainnet to support multiple applications within its ecosystem and to control underlying block parameters and economic models.

Previously, customers deployed their applications on public networks, facing uncontrollable gas costs and performance. The core challenges are not just the chain itself, but also the complete delivery of the entire package—block explorer, cross-chain bridge, node deployment tools, and developer documentation—so the ecosystem can use them as soon as they get them.

The scope we undertake

Chain core (consensus, block production, gas model), block explorer, cross-chain bridge, node deployment tools, developer documentation.

Scope 1
Chain Core (Consensus, Block Production, Gas Model)
Scope 2

Scope 3
Cross-chain bridge
Scope 4
Node deployment tools
Scope 5

Key technical decisions

Decision 01
Chain framework: Self-built vs vs ready-made frameworks
Customized based on mature frameworks rather than building chains from scratch, it achieves EVM compatibility and allows for custom block parameters, shortening delivery cycles and reducing long-term maintenance risks.
Decision 02
Gas model customization
Customize gas billing and allocation models based on the application characteristics of the customer ecosystem, balancing network sustainability with user costs.
Decision 03
Supporting facilities delivered in one go
Browsers, cross-chain bridges, node tools, and blockchain tools are delivered simultaneously, preventing ecosystem members from obtaining a "bare chain" that cannot be implemented.
