Chia Blockchain VDF
Chia is a blockchain and smart transaction platform based on proofs of space and time rather than proofs of work with other cryptocurrencies. This test profile is benchmarking the CPU performance for Chia VDF performance using the Chia VDF benchmark. The Chia VDF is for the Chia Verifiable Delay Function (Proof of Time).
To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark chia-vdf.

Performance Metrics
Analyze Test Configuration:Chia Blockchain VDF 1.0.1
Test: Square
OpenBenchmarking.org metrics for this test profile configuration based on 57 public results since 1 May 2021 with the latest data as of 5 May 2021.
Below is an overview of the generalized performance for components where there is sufficient statistically significant data based upon user-uploaded results. It is important to keep in mind particularly in the Linux/open-source space there can be vastly different OS configurations, with this overview intended to offer just general guidance as to the performance expectations.
Based on OpenBenchmarking.org data, the selected test / test configuration (Chia Blockchain VDF 1.0.1 - Test: Square) has an average run-time of 2 minutes. By default this test profile is set to run at least 3 times but may increase if the standard deviation exceeds pre-defined defaults or other calculations deem additional runs necessary for greater statistical accuracy of the result.
Based on public OpenBenchmarking.org results, the selected test / test configuration has an average standard deviation of 0.6%.
