Performance

You might be wondering how fast is the work generation. There’s a pow-benchmark example in the examples/ directory. On an Intel Core i7-8550U CPU, with 100 iterations, the average computation time is 18.5s per work.

Considering you can pre-compute and cache the work prior to an actual transaction, this should be satisfying for a smooth user experience.

Contribute

Contributions are very welcome. To develop, make use of the following commands (using Yarn):

• yarn build:dev: build the C++ code to WebAssembly and bundle the files into the dist/ directory, without optimization so that it is fast while developing. Note that you’ll need to have Docker installed

• yarn test: test the code

• yarn lint: lint the code against JavaScript Standard Style

• yarn generate-docs: generate the docs/ website from the JSDoc annotations
