- Generate seeds
- Derive secret keys, public keys and addresses
- Hash blocks

- Check the format of seeds, secret keys, public keys, addresses, amounts, etc.
- Convert Nano units
- CLI doing all of the above
To install the library:
npm install btcocurrency # or yarn add btcocurrency
import * as btcocurrency from 'btcocurrency'
You might be wondering how fast is the work generation. There's a
pow-benchmark example in the
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.
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 generate-docs: generate the
docs/website from the JSDoc annotations
