Blockchain Protocol Engineering

B-Harvest provides specialized blockchain core development and protocol engineering services for high-performance Layer 1 blockchains and Layer 2 scaling solutions. Their expertise spans custom blockchain implementations, consensus mechanisms, and advanced execution optimizations.

Layer 1 Development

The team delivers custom blockchain core development for high-throughput Layer 1 networks, implementing ABCI 2.0 (Application Blockchain Interface) for efficient communication between blockchain applications and consensus engines. Their work includes optimistic parallel execution implementations that dramatically improve transaction throughput, storage optimization techniques that reduce blockchain state bloat, and custom solutions for network bottleneck optimization.

Layer 2 & Polygon CDK Solutions

B-Harvest specializes in Polygon CDK (Chain Development Kit) implementations, focusing on decentralizing sequencers with CometBFT consensus to move away from centralized architectures toward robust, decentralized ordering systems. They implement BLS (Boneh-Lynn-Shacham) signature schemes for efficient consensus verification, enabling signature aggregation that reduces data requirements. The team builds communication interfaces between Cosmos-based chains and zkEVM environments using ABCI 2.0, enabling interoperability between distinct blockchain architectures.

Technical Expertise

With extensive experience in Cosmos SDK, CometBFT (formerly Tendermint), and various blockchain frameworks, B-Harvest has contributed key features to major blockchain protocols through Interchain Foundation grants, including validator key rotation, double-signing protection, and improved peer management systems. Their 173 public repositories on GitHub demonstrate active contributions to leading blockchain projects including Cosmos, Polkadot, Kava, Injective, Terra, and Initia.

Why Choose B-Harvest

B-Harvest combines theoretical knowledge with practical implementation experience, having proven their technical excellence during critical network operations like the Initia Testnet surge where they resolved stability issues affecting 200-300k users. Their development team is ideal for projects requiring custom Layer 1 blockchain solutions, Layer 2 implementations, or performance enhancements to existing protocols.
