This is a simple blockchain written in Go
Implementing Proof Of Work to validate and confim transactions.
Please refer to the latest lesson on this README file.
Assuming you are using WSL. Install Go from the official website (require 1.16 or later). Copy the folder name Go you just downloaded to :
/usr/local/ Paste this into your bash or zsh to add enviroment path
export PATH=$PATH:/usr/local/go/bin- Clone the repository
git clone https://github.com/yourusername/golang-blockchain.git- Navigate to the project directory
cd golang-blockchain- Build the project
go build -o <ANY NAME>Replace <ANY NAME> with the name you like.
After the project is being built, you can run the binary with these commands:
- To add block to the chain:
./<ANY NAME> add -block "<BLOCK DATA>"- To print the blockchain:
./<ANY NAME> print Replace <ANY NAME> with the above name you just set and <BLOCK DATA> with the data of the block
For this lesson there are some changes to the code. So some commands are new and some are inapplicable. Here are some that works:
- To create a blockchain:
go run main.go createblockchain -address "<ANY NAME>"- To print the Blockchain:
go run main.go print - To send some ammount of money:
go run main.go send -address "<ANY NAME>" -to "<RECEIVER>" -ammount "<AMOUNT>"- To get the balance of any address:
go run main.go getbalance -address "<ANY NAME>"| Command | Description |
|---|---|
-address |
The wallet address that will be used for this operation |
-to |
The recipient's wallet address |
-amount |
The amount of coins to be sent |
|
Replace <ANY NAME> with the above name (or your address) you just set, <RECEIVER> with the address of the receiver and <AMOUNT> with the ammount of money you want to send.
❗ ATTENTION
Remember to delete the tmp files before running the commands. You can do it simply by deleting the tmp folder in the project directory or a more PROFESSIONAL way is to run the command rm -r tmp.
