Welcome to this smart contract workshop organised by Extropy. In this tutorial, we are going to build a simple Score Dapp on Ethereum. You are going to learn Solidity, a programming language to create smart contracts on the Ethereum blockchain.

Solidity is a statically typed language. So you always need to declare the variable type here uint before the variable name. You can also specify the number of bits, by range of 8 bits. Here are some examples below:. We need a way to write and retrieve the value of our score. We achieve this by creating a getter and setter functions. In Solidity, you declare a function with the keyword function followed the function name here getScore.

Definition : In Solidity, a setter is a function that modifies the value of a variable modifies the state of the contract. To creates a setter , you must specify the parameters when you declare your function. Try entering this code in Remix. We are still not there. The compiler should give you the following error:. There are four types of visibility for functions in Solidity : public , private , external and internal. The table below explains the difference.

Try entering that in Remix. We are still not getting there! You should receive the following Warning on Remix. Because our function getScore only reads from the contract state, it is a view function. The msg variables offers two associated fields:. We should have a feature that enables only certain addresses to change the score your address. To achieve this, we will introduce the notion of modifiers.

Definition : A modifier is a special function that enables us to change the behaviour of functions in Solidity. It is mostly used to automatically check a condition before executing a function. Check that the address of the caller msg. If 1 is true, it passes the check. A modifier can receive arguments like functions. Here is an example of a modifier that requires the caller to send a specific amount of Ether.

We will define that in the constructor. Definition : A constructor is a function that is executed only once when the contract is deployed on the Ethereum blockchain. Constructors are optional. Prior to version 0. This syntax was deprecated and is not allowed in version 0. Events are only used in Web3 to output some return values. They are a way to show the changes made into a contract. To illustrate, we are going to create an event to display the new score set.

This event will be passed within our setScore function. Remember that you should pass the score after you have set the new variable. It will create an index that will enable to search for eventsvia Web3 in your front-end. However, they are only visible outside the contract. Any recursive function can be rewritten into an iterative one.

But for many tasks a recursive solution is fast enough and easier to write and support. Naturally, the formula is the fastest solution. It uses only 3 operations for any number n. The math helps! The loop variant is the second in terms of speed. In both the recursive and the loop variant we sum the same numbers. But the recursion involves nested calls and execution stack management. That removes the burden on memory, so counting sumTo becomes possible.

The factorial of a natural number is a number multiplied by "number minus one" , then by "number minus two" , and so on till 1. The factorial of n is denoted as n! The task is to write a function factorial n that calculates n! Hint: n! For instance: 3! In other words, the result of factorial n can be calculated as n multiplied by the result of factorial n And the call for n-1 can recursively descend lower, and lower, till 1.

The basis of recursion is the value 1. In other words, the next number is a sum of the two preceding ones. Fibonacci numbers are related to the Golden ratio and many natural phenomena around us. The function should be fast. The call to fib 77 should take no more than a fraction of a second. For instance, fib 77 may hang up the engine for some time eating all CPU resources. The same values are re-evaluated again and again. Here we can see that the value of fib 3 is needed for both fib 5 and fib 4.

So fib 3 will be called and evaluated two times completely independently. We can clearly notice that fib 3 is evaluated two times and fib 2 is evaluated three times. We can optimize that by remembering already-evaluated values: if a value of say fib 3 is calculated once, then we can just reuse it in future computations. Instead of going from n down to lower values, we can make a loop that starts from 1 and 2 , then gets fib 3 as their sum, then fib 4 as the sum of two previous values, then fib 5 and goes up and up, till it gets to the needed value.

On each step we only need to remember two previous values. The approach is called dynamic programming bottom-up. Please note that we use a temporary variable tmp to walk over the list. Technically, we could use a function parameter list instead:. In the future we may need to extend a function, do something else with the list. If we change list , then we lose such ability.

Talking about good variable names, list here is the list itself. The first element of it. And it should remain like that. From the other side, the role of tmp is exclusively a list traversal, like i in the for loop. The recursive variant of printList list follows a simple logic: to output a list we should output the current element list , then do the same for list.

Technically, the loop is more effective. These two variants do the same, but the loop does not spend resources for nested function calls. Output a single-linked list from the previous task Output a single-linked list in the reverse order. So what we can do is to first go through the items in the direct order and remember them in an array, and then output what we remembered in the reverse order:.

Please note that the recursive solution actually does exactly the same: it follows the list, remembers the items in the chain of nested calls in the execution context stack , and then outputs them. We want to make this open-source project available for people all around the world.

Tutorial map. Light theme Dark theme. Our first topic will be recursion. If you are not new to programming, then it is probably familiar and you could skip this chapter. Recursion is usually shorter. A recursive solution is usually shorter than an iterative one. Please note:. Tasks Sum all numbers till the given one. The solution using a loop:. Calculate factorial. We can write a definition of factorial like this: n! By definition, a factorial n! Fibonacci numbers. Write a function fib n that returns the n-th Fibonacci number.

The first solution we could try here is the recursive one. Fibonacci numbers are recursive by definition:. Output a single-linked list. Loop-based solution Loop-based solution The loop-based variant of the solution:. Recursive solution Recursive solution The recursive variant of printList list follows a simple logic: to output a list we should output the current element list , then do the same for list.

Output a single-linked list in the reverse order. Make two solutions: using a loop and using a recursion. Using a recursion Using a recursion The recursive logic is a little bit tricky here. We need to first output the rest of the list and then output the current one:. Using a loop Using a loop The loop variant is also a little bit more complicated than the direct output.
