What is a Blockchain Smart Contract?
So a Blockchain smart contract is like a normal contract such as your mobile phone contract. But it’s digital and only consists of a few lines of code in the blockchain.
Partners can interact with a smart contract. The blockchain executes the code and documents the transactions. So let’s explain it with a simple example:
Surely you are already familiar with Kickstarter. It is a large platform for crowdfunding. So companies can go there and create a project. You can set a funding target to collect money from other people. So Kickstarter is a third party sitting between the production team and the sponsors. Thus, both sides must trust them to handle their money mindful. So if the project reaches the minimum sum, they transfer the money. But if they don’t reach the goal, each one gets their money back.
Ethereum Smart Contracts Example
As you can see, we always need a third party as a trusted instance. So smart contracts allow you to collect funds without a central instance. Thus, this makes the whole process safer and more efficient. It also makes sure that the money gets into the right hands. So now let’s create a smart contract:
The companies, in our case a production team, creates a campaign with a smart contract. So it defines the input for the funding target as well as the period of the project. Users can become sponsors by sending their money to the smart contract. So he manages and verifies the money as follows:
- If the amount is higher than the minimum value, you are a sponsor in the smart contract.
- If the amount is lower, it is discarded and the user gets his money back.
Benefits of Blockchain Smart Contracts
If they don’t reach the funding in time, all sponsors will get their money back. That way, you don’t have to run after your money.
If they reach it, they transfer the money to the production team. It is then used to start the project. Blockchain Technology Smart Contracts allow them to don’t waste time with contracts.
How does a Blockchain Smart Contract work?
So who checks now if the sponsors really get their promised services? Is the money really used for the actual product? The sponsors must trust the production team. It often happens that nobody gets the product or they don’t even produce them.
With an Ethereum smart contracts, we now have the chance to control it. So the production team can create the desired output. It defines the price, product, quantity and even suppliers. As a result, the lenders can vote once their favorite product. They decide whether the purchase makes sense or not.
If the product reaches an approval above 50%, the supplier gets the money and the order is placed. Thus, the owner always has control over his money and a violation of trust is impossible.
That is impressive when you consider that everything is realized only with the help of a few lines of code. And because Blockchain smart contracts are on top of the blockchain, the contracts are decentralized. So this means that no central party necessary, and so we have no additional costs. Thus, this allows companies to optimize processes and save money.
Why should you trust Blockchain Smart Contracts?
Humans programmed them and can, therefore, abuse your trust. So to answer this question, we need to take a closer look at the characteristics of a blockchain:
Since smart contracts are on a blockchain, they get some interesting features. So they are unchangeable. This means when you create them, nobody can change it. Thus, nobody can manipulate a smart contract behind your back and change the code. On the other hand, they run on a distributed platform. So everyone owns a copy of the contract and reviews it.
So if someone intends to manipulate your contract each person on the network will discover and report the scam attempt. The manipulation of a smart contract is therefore virtually impossible.
“Ethereum Smart Contracts explained” – Summarized:
- A smart contract is a digital contract.
- It consists of a few lines of programming code.
- So more control for both parties.
- Therefore, no central trust party.
- You can’t change a smart contract.
- it creates more security for all.
