In the bustling realm of supply chains, where products travel from manufacturer to consumer, transparency and reliability are paramount. Imagine a digital fortress, a Blockchain Supply Chain, ensuring the authenticity and availability of every product. Today, we delve into the heart of this innovative marvel, exploring the intricacies of the code that powers it.
Well, You and I may not be go lang blockchain experts, but we can start from somewhere. And on that note, comment with areas in which I can enhance the code or correct it, even if its basic.
The Power of Blockchain Supply Chain: Bringing Transparency to Life
This code serves as the gateway to a world where every product’s journey is traceable and transparent. Through this digital marvel, supply chain professionals gain real-time insights into product availability, supplier information, and much more. Blockchain technology ensures the integrity of this information, making our supply chain not just efficient, but trustworthy.
Moreover, this simple, elegant piece of code symbolizes the fusion of technology and business acumen, transforming the conventional supply chain into a transparent, reliable, and cutting-edge Blockchain Supply Chain. With each line of code, a new chapter in supply chain management unfolds, promising a future where transparency is not just a buzzword but a fundamental reality.
Welcome to the future. Welcome to the Blockchain Supply Chain.

Understanding the Code: A Closer Look
package main
import (
“net/http”
“log”
“fmt”
)
// Product represents a product in our inventory
type Product struct {
Name string
SKU string
Supplier string
Availability bool
}
// Our inventory is a slice of Products
var inventory = []Product{
{“Product A”, “SKU_A”, “Supplier A”, true},
{“Product B”, “SKU_B”, “Supplier B”, false},
{“Product C”, “SKU_C”, “Supplier C”, true},
}
func main() {
setupServer()
}
func getHTMLResponse() string {
html := “<!DOCTYPE html><html lang=\”en\”><head><meta charset=\”UTF-8\”><meta name=\”viewport\” content=\”width=device-width, initial-scale=1.0\”><title>Blockchain Supply Chain</title></head><body><header role=\”banner\”><h1>Blockchain Supply Chain</h1></header><main role=\”main\”>”
for _, product := range inventory {
html += fmt.Sprintf(“<section aria-label=\”%s details\”><h2>%s</h2><p>SKU: <span id=\”%s_SKU\”>%s</span></p><p>Supplier: <span id=\”%s_Supplier\”>%s</span></p><p>Warehouse Availability: <span id=\”%s_Availability\”>%t</span></p></section>”, product.Name, product.Name, product.Name, product.SKU, product.Name, product.Supplier, product.Name, product.Availability)
}
html += “</main><footer role=\”contentinfo\”><p>© 2022 Blockchain Supply Chain</p></footer></body></html>”
return html
}
func handleRequest(w http.ResponseWriter, r *http.Request) {
html := getHTMLResponse()
_, err := w.Write([]byte(html))
if err != nil {
handleError(err)
}
}
func handleError(err error) {
log.Println(“An error occurred:”, err)
}
func setupServer() {
http.HandleFunc(“/”, handleRequest)
log.Println(“Starting server on port 8080…”)
err := http.ListenAndServe(“:8080”, nil)
if err != nil {
handleError(err)
}
}
In the world of programming, this robust system is constructed using the Go programming language. Go, known for its simplicity and efficiency, is the backbone upon which our Blockchain Supply Chain stands tall.
1. The Product Structure:
type Product struct {
Name string
SKU string
Supplier string
Availability bool
}
In this section, the products are not just items on a shelf; they are digital entities represented by this structure. Each product has a name, a unique SKU (Stock Keeping Unit), a supplier, and an availability status.
2. The Inventory:
var inventory = []Product{
{“Product A”, “SKU_A”, “Supplier A”, true},
{“Product B”, “SKU_B”, “Supplier B”, false},
{“Product C”, “SKU_C”, “Supplier C”, true},
}
Here lies the array of products, each with its distinct characteristics, forming the foundation upon which our Blockchain Supply Chain operates.
3. Creating the Web Server:
func setupServer() {
http.HandleFunc(“/”, handleRequest)
log.Println(“Starting server on port 8080…”)
err := http.ListenAndServe(“:8080”, nil)
if err != nil {
handleError(err)
}
}
This function sets up the web server, making our Blockchain Supply Chain accessible to the world via HTTP.
4. Handling Requests:
func handleRequest(w http.ResponseWriter, r *http.Request) {
html := getHTMLResponse()
_, err := w.Write([]byte(html))
if err != nil {
handleError(err)
}
}
When a request is made to the server, this function crafts the HTML response dynamically. It meticulously compiles the details of each product, including its name, SKU, supplier, and warehouse availability.
5. Generating HTML Response:
func getHTMLResponse() string {
// … (HTML generation logic)
return html
}
This function intricately designs the HTML response by iterating through the inventory, creating detailed sections for each product. The resulting HTML showcases essential product information, making it comprehensible and user-friendly.
Simply...
Code Explanation
Let’s break down the code:
- Package main: Every Go program starts running in a package called main.
- Import statement: This is where we import other packages that we need in our program.
- Type declaration: We declare a new type called
Productwhich is a struct with four fields:Name,SKU,Supplier, andAvailability. - Variable declaration: We declare a variable called
inventorywhich is a slice ofProduct. This represents our list of products. - Functions: We have several functions in our code:
- The
mainfunction sets up the server. - The
getHTMLResponsefunction generates an HTML string that includes information about each product in our inventory. - The
handleRequestfunction writes the HTML response to the HTTP response writer. - The
handleErrorfunction logs any errors that occur. - The
setupServerfunction sets up the HTTP server and starts listening for requests.

How Can This Tool Be Used in Supply Chain Management?
This simple Go server can serve as a starting point for a more complex blockchain supply chain management tool. Here are some ways it could be expanded:
- Integrate with a blockchain: The server could interact with a blockchain network to retrieve real-time product information. This would involve implementing a blockchain client in Go and making API calls from the server to the blockchain network.
- Add more features: We could add more features to our HTML page, such as search functionality or detailed product pages.
- Improve error handling: We could improve our error handling logic to provide more informative error messages to the client.
- Scale up: If the tool needs to handle high traffic, we could scale it up using cloud services or containerization technologies like Docker and Kubernetes.
In conclusion, Go is a powerful language for building web servers and can be an excellent choice for implementing blockchain supply chain management tools. With its simplicity, efficiency, and robust standard library, Go enables developers to build scalable and reliable web applications with ease. Happy coding! 😊
