Download this project.\n2. Install [Racket](https://download.racket-lang.org/).\n3. Install the dependencies. In the project root directory, execute in a shell: `make deps`.\n\n## Example Usage\n\n1. Run the first peer. In the project root directory, execute in a shell:\n\n    ```bash\n    racket src/main-p2p.rkt test.data 7000 127.0.0.1:7001,127.0.0.1:7002\n    ```\n\n2. You will see output like the following. When you do, press _control-c_ to break execution.\n\n    ```bash\n    Making genesis transaction...\n    Mining genesis block...\n    #\u003cthread:export-loop\u003e\n    Mined a block!\n    Exported blockchain to 'test.data'...\n    ```\n\n3. Run the second peer. In the project root directory, execute in a shell:\n\n    ```bash\n    racket src/main-p2p.rkt test2.data 7000 127.0.0.1:7001\n    ```\n\n4. To sync the peers, run the first peer again while keeping the second peer active. In the project root directory, execute in a shell:\n\n    ```bash\n    racket src/main-p2p.rkt test.data 7000 127.0.0.1:7001,127.0.0.1:7002\n    ```\n\nTo run the tests, in the project root directory, execute in a shell:\n\n```bash\nmake test\n```\n\n## Maintainer\n\nBracken Spencer\n\n* [GitHub](https://www.github.com/brackendev)\n* [LinkedIn](https://www.linkedin.com/in/brackenspencer/)\n* [Twitter](https://twitter.com/brackendev)\n\n## License\n\nBlockchain-Racket is released under the GNU General Public License.
