;; Simple Storage Contract

;; 1. Define the Data Variable
;; This creates a persistent variable named 'store' that holds a uint (unsigned integer)
(define-data-var store uint u0)

;; 2. Public Function: Set Value
;; This allows any user to update the stored value.
(define-public (set-value (new-value uint))
    (begin
        ;; Update the data variable
        (var-set store new-value)
        ;; Return a success response
        (ok true)
    )
)

;; 3. Read-Only Function: Get Value
;; This retrieves the current value without costing gas/transaction fees.
(define-read-only (get-value)
    (ok (var-get store))
