+ <h2><a href="https://www.npmjs.com/package/nano-pow">https://www.npmjs.com/package/nano-pow</a></h2>
+ <p>This benchmark tests a browser-based proof-of-work implementation for the cryptocurrency Nano. A random 32-byte value is generated for a block hash, and then the test uses this value to find a nonce that meets a minimum threshold.</p>
<p>NanoPow uses cutting edge WebGPU technology, and not all browsers support it.</p>
- <p>NanoPow uses WebGL 2.0 as a fallback option if WebGPU is not detected and a WASM module if neither GPU API is available.</p>

<p>Times below are in milliseconds and are summarized by various averaging methods.</p>
<p>Level of Effort depends on hardware and does not guarantee faster results.</p>
+ <ul>
+ <li>Each work_generate call is individually timed.</li>
+ <li>Each test is comprised of the specified iterations of calls.</li>
+ <li>Each test run is comprised of the specified iterations of tests.</li>
+ </ul>
+ <p>The final score is displayed as "work-per-second" and is calculated as follows:</p>
+ <ol>
+ <li>For each test run:
+ <ol>
+ <li>Collect all the work_generate timings for the test run.</li>
+ <li>Truncate the results by eliminating the fastest 10% and slowest 10% of sequence timings.</li>
+ <li>Calculate the arithmetic mean (average) of the truncated results.</li>
