Welcome to the Hyperledger Caliper project. Caliper is a blockchain performance benchmark framework, which allows users to test different blockchain solutions with predefined use cases, and get a set of performance test results.

Currently supported blockchain solutions:

• Hyperledger Besu, utilizing the Ethereum adapter.
• Hyperledger Fabric v1.X, v2.X
• Ethereum

Currently supported performance indicators:

• Success rate
• Transaction/Read throughput
• Transaction/Read latency (minimum, maximum, average)
• Resource consumption (CPU, Memory, Network IO, …)

See the PSWG white paper to find out the definitions and corresponding measurement methods.

For more information on using Caliper, please consult the documentation site

Configuration and usage

See the related documentation page.

How to contact us

If you have any issues using Caliper that the documentation does not help you solve, please reach out to us through the following methods:
