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 Fabric v1.X](https://github.com/hyperledger/fabric)
* [Hyperledger Sawtooth 1.0+](https://github.com/hyperledger/sawtooth-core)
* [Hyperledger Iroha 1.0 beta-3](https://github.com/hyperledger/iroha)
* [Hyperledger Burrow 1.0](https://github.com/hyperledger/burrow)
* [Ethereum](https://github.com/ethereum/go-ethereum)
* [Hyperledger Besu](https://github.com/hyperledger/besu), utilizing the Ethereum adapter.
* [FISCO BCOS](https://github.com/FISCO-BCOS/FISCO-BCOS)
* [Hyperledger Composer](https://github.com/hyperledger/composer) support has been deprecated, and will be removed in 0.3.0.

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](https://www.hyperledger.org/resources/publications/blockchain-performance-metrics) to find out the definitions and corresponding measurement methods.
