Has any group managed to embed a hash of a smart contract in an image , video via smart phone including a GPS based location ?
Thanks
Has any group managed to embed a hash of a smart contract in an image , video via smart phone including a GPS based location ?

Here is an AI generated code to give some meaning .
Here is some sample code in Motoko for the Internet Computer that embeds a hash of a smart contract into an image to track delivery of goods using GPS:
Is this acceptable.
Cheers
import Nat "mo:base/Nat";
import Hash "mo:base/Hash";
import Text "mo:base/Text";
import Blob "mo:base/Blob";
import Gps "canister:gps";
actor {
public type CustomerInfo = {
name: Text;
address: Text;
orderId: Nat;
};
stable var customers : [(Nat, CustomerInfo)] = [];
public shared({caller}) func addCustomer(info: CustomerInfo) : async () {
let uid = customers.size();
customers := Array.append([(uid, info)], customers);
};
public query func getCustomer(id: Nat) : async ?CustomerInfo {
return Array.find<CustomerInfo>(customers, func (x) { x.0 == id });
};
public shared({caller}) func deliveryComplete(id: Nat) : async () {
switch (getCustomer(id)) {
case null return;
case (?customer) {
// Get current GPS location
let location = await Gps.getCurrentLocation();
// Hash the delivery details
let payload = Blob.toArray(Text.encodeUtf8(
"Delivery to " # customer.name # " at " # customer.address # " completed at " #
Nat.toText(location.latitude) # "," # Nat.toText(location.longitude)
));
let hash = Hash.hash(payload);
// Embed hash into delivery confirmation image
let image = embedHashInImage(hash);
// Send image to customer
};
};
};
func embedHashInImage(hash: [Nat8]) : Blob {
// Embed hash data into image
return imageBlob;
};
}
This defines a simple actor that stores customer information, gets their current GPS location when a delivery is completed, hashes the delivery details, embeds the hash into an image, and then sends the image to the customer. The key parts are:
The image with the embedded hash can act as a receipt proving successful delivery. The customer can verify the details in the hash match what they ordered. This allows tracking deliveries on a tamper-proof ledger on the Internet Computer.
Have a potentially large application that requires a group formation to achieve outcome .
Is there a good method to bring together a group with people with the right skills to develop ?
