This project was bootstrapped with Create React App.
This game shows how new blocks are added to the blockchain in Bitcoin. It gives a pretty good feel for how proof-of-work works.
Select transaction on the left, and then try to add the block. Start by clicking 'Calculate SHA256 hash'. If the calculated hash ends in a '0', you can add the block by clicking 'Add block'. If not, change the nonce and try again.
- I'd like to make it a multiplayer game. I imagine a classroom teacher could create a private session, and all the students in the class could compete to mine new blocks. The algorithm would automatically adjust its difficulty after a set number of minutes, so students could see that working in practice.
- It could be more obvious how the blockchain is verified, how each block has a 'previous block' hash pointing back at the previous block, thus linking all the blocks, which cannot be tampered with without going through the proof-of-work again for each block.
- Obviously I'd like improve the look of the project (colors, graphics, layout, etc).
You can pull the project and run it as follows.
Runs the app in the development mode.
Open http://localhost:3000 to view it in your browser.
The page will reload when you make changes.
You may also see any lint errors in the console.
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
Builds the app for production to the build
folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
Note: this is a one-way operation. Once you eject
, you can't go back!
If you aren't satisfied with the build tool and configuration choices, you can eject
at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject
will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.
You don't have to ever use eject
. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
