DataHaven 🫎

Based on polkadot-sdk-solochain-template

Benchmarking

DataHaven uses runtime benchmarking to generate accurate weight calculations for all pallets. The benchmarking process is automated using frame-omni-bencher.

Requirements

Make sure you have the lastest rust version

• frame-omni-bencher - Install with: cargo install frame-omni-bencher --profile=production (or cargo install --git https://github.com/paritytech/polkadot-sdk frame-omni-bencher --profile=production --locked)

Running Benchmarks

Execute the benchmarking script from the project root:

# Benchmark all pallets for testnet runtime (default)
./scripts/run-benchmarks.sh

# Benchmark specific runtime
./scripts/run-benchmarks.sh mainnet

# Custom steps and repetitions
./scripts/run-benchmarks.sh testnet 100 50

The script will:

1. Automatically discover all available pallets
2. Build the runtime WASM with runtime-benchmarks feature
3. Generate weight files in runtime/{runtime}/src/weights/
4. Provide a summary of successful and failed benchmarks

Script Parameters

• runtime: Runtime to benchmark (testnet, stagenet, mainnet). Default: testnet
• steps: Number of steps for benchmarking. Default: 50
• repeat: Number of repetitions. Default: 20

Zombienet testing

First, install zombienet.

To spawn a local solo chain with four validators and BABE finality, run:

zombienet -p native spawn test/config/zombie-datahaven-local.toml
