Single command network spin-up
What We Were Solving
Sisu Network was building a revolutionary cross-chain DeFi protocol enabling seamless token transfers between Ethereum, BSC, Polygon, and other EVM-compatible chains. The technical complexity of running a distributed validator network with Threshold Signature Scheme (TSS) cryptography required sophisticated infrastructure automation.
Infrastructure challenges:
- Three interdependent services — Sisu validator core, Dheart TSS signing engine, and Deyes chain watcher — needed coordinated deployment
- Multi-node testing required to validate consensus mechanisms and distributed key generation ceremonies
- Engineers needed local blockchain networks (Ganache) for testing cross-chain transfers without mainnet gas costs
- Dynamic configuration generation required for N validators with unique keys, ports, and peer discovery settings
- Cosmos SDK-based architecture required specific database and networking configurations
How We Solved It
We containerized the entire blockchain validator stack with Docker Compose, enabling reproducible multi-node deployments for both development and production environments.
Docker Compose Orchestration
Created comprehensive Docker Compose configurations orchestrating all validator components with single-command deployment. The stack includes Sisu validator nodes, Dheart TSS signing services, Deyes chain watchers, Ganache EVM chains, and MySQL databases.
Dynamic Multi-Node Configuration
- Built configuration generator that creates docker-compose files for N validators with unique cryptographic keys
- Automated peer discovery configuration ensuring all validators can find and communicate with each other
- Port mapping and networking configuration for inter-service communication
CI/CD Pipeline
- GCP Cloud Build pipeline for automated container builds on every commit
- Automated testing of cross-chain transfers using CLI commands for token deployment and bridging
Development Tooling
Created CLI commands for common development tasks: funding test accounts, deploying ERC20 tokens, initiating cross-chain transfers, and monitoring validator consensus — dramatically accelerating the development feedback loop.
Technologies Used
“The Docker Compose setup transformed our development workflow. Spinning up a full multi-node validator network went from a day-long manual process to a single command. Testing TSS signing across nodes is now straightforward.”
