To make secure and borderless digital value transactions, it is important to establish a contractual agreement. Thanks to the Smart Contract, it is now easy to secure a contractual process.
It is a decentralized application that limits transaction costs and losses due to fraud. Smart Contract is notably deployed on a blockchain protocol.
Blockchain is a digital technology for storing and transferring data. It is highly secure and operates in a decentralized and transparent manner. Blockchain does not require a central control body to manage its transactions.
This is the digital equivalent of a traditional contract. A Smart Contract is in fact a computer program established by the cryptographer and scientist Nick Szabo. It allows certain contractual agreements to be automatically executed.
A Smart Contract is linked directly to the blockchain and automates transactions of value in the form of cryptocurrencies. Its main strength is to guarantee the accuracy of the conditions of its execution.
Unlike a traditional contract, the rules are clearly set in a blockchain, ensuring reliable interpretation of the code. This helps secure the data and prevents it from being deleted or modified. When all contractual conditions are properly verified, the blockchain immediately automates transactions.
The exchanges are public and can be viewed by anyone to verify the accuracy of the terms offered. There are also standardized smart contracts for which templates can be used.
The Smart Contract is therefore a computer code that facilitates the collaboration of two parties, without an intermediary. This makes it possible to considerably reduce the transaction costs linked to the transmission of contracts.
A Smart Contract has many advantages. First, it perfectly ensures the security of exchanges between two parties. Indeed, the data entered in the blockchain cannot be modified or deleted. The agreement thus remains stable and intact even if there is a party who breaks the terms of the contract.
This system also offers great autonomy to its users, allowing them to have complete control over the agreement. The Smart Contract does not require the intervention of a third party such as a notary, a lawyer, etc.
Creating a Smart Contract is often dedicated to web developers. Generally, the programming language used for designing a decentralized application is "Solidity". To do this, it must follow 4 major steps.
The first step is writing the Smart Contract. It consists of declaring the data types and variables in order to write the functions properly. The second step is to test the Smart Contract by integrating it into a local blockchain first.
From insurance to logistics, real estate and agri-food, the Smart Contract has many possible outlets. It is very practical for exchanging goods or money. It can also be applied in the entertainment sector, in the media and in the energy sector.
Insurance companies use it to establish offers determined by circumstantial elements. Depending on where the car is located, an insurer can advance different policies with a Smart Contract.
There are several blockchains that can deploy a smart contract or a Smart Contract. Ethereum, for example, is made up of many decentralized applications configured from the Smart Contract.
What is a blockchain?
Blockchain is a digital technology for storing and transferring data. It is highly secure and operates in a decentralized and transparent manner. Blockchain does not require a central control body to manage its transactions.
Instead, it acts as several blocks connected to each other in order to form a link. All actions performed will then be archived in the form of a secure and digitized chain of information.
The blockchain is thus a kind of database shared simultaneously with all its users. It contains the history of all transactions carried out between them since its creation.

Its scope of application is much larger than that of crypto-assets or cryptocurrencies. For its execution, each party must first identify themselves using a cryptographic process.
The transaction will then be sent to a storage node hosting a copy of the ledger containing the exchanges made. Thus, all users can access it at the same time.

However, each piece of information added will first be decrypted by data centers before being validated. Once authenticated, the transaction is added as a block of encrypted information in the database. Hence the name "block".
What is a Smart Contract?
This is the digital equivalent of a traditional contract. A Smart Contract is in fact a computer program established by the cryptographer and scientist Nick Szabo. It allows certain contractual agreements to be automatically executed.
However, the smart contract is governed by a computer code and does not require the intervention of a trusted third party. On the other hand, a legal framework often regulates the execution of a traditional agreement.
The Smart Contract generally relies on blockchain digital technology to secure the terms of its execution. Once the pre-defined conditions are met, it immediately executes what is written in its code. Thus, the transactions will be irreversible, fast, tamper-proof and transparent.
Typically, the Smart Contract has a user interface. However, even if the user interface were to disappear, users can still interact with the Smart Contract. The Smart Contract will only be inaccessible when the network on which it is hosted is shut down.

Hence a significant reduction in the costs associated with signing the agreement. This decentralized application also improves the overall efficiency of data processing, as it minimizes personal participation.
In addition, the use of the Smart Contract allows you to benefit from an environment that guarantees the completion of the exchange without problems.

The smart contract further guarantees trust between all participants. It also eliminates the risk of non-payment, because the payment processes are automated.
What are the steps to follow to create a Smart Contract?
Creating a Smart Contract is often dedicated to web developers. Generally, the programming language used for designing a decentralized application is "Solidity". To do this, it must follow 4 major steps.
The first step is writing the Smart Contract. It consists of declaring the data types and variables in order to write the functions properly. The second step is to test the Smart Contract by integrating it into a local blockchain first.
This is done using software such as Ganache or Test RPC. The developer will also be able to simulate the Ethereum blockchain in this way. The test can also be done with a public blockchain such as Ropsten.
The next step is writing the web interface. Finally, the last step is compiling it and integrating it into the real blockchain. This effectively allows all its users to easily access the decentralized application.

What are the areas concerned by the Smart Contract?
From insurance to logistics, real estate and agri-food, the Smart Contract has many possible outlets. It is very practical for exchanging goods or money. It can also be applied in the entertainment sector, in the media and in the energy sector.
Insurance companies use it to establish offers determined by circumstantial elements. Depending on where the car is located, an insurer can advance different policies with a Smart Contract.
There is certainly a difference in compensation between driving on a deteriorated road and driving on a good one.
In the real estate sector, the Smart Contract allows for accelerated transaction action. Thus, the transfer of payment for a property via a conventional deposit is no longer required. It is even possible to register it in an unfalsifiable land register.

This computer code can also be used in delivery services. For this, it will ensure that the money is sent to the service provider only upon receipt of the package. The sender only has to simply fill in the Smart Contract with a cryptocurrency in order to manage everything.
Some examples of Smart Contract
There are several blockchains that can deploy a smart contract or a Smart Contract. Ethereum, for example, is made up of many decentralized applications configured from the Smart Contract.
It is also the most popular blockchain that ensures a high level of security. In addition, the most reliable smart contracts are programmed on Ethereum.
Depending on the sector of activity, we can find several types of Smart Contract. In the field of decentralized monetary projects, cryptocurrencies such as MakerDAO, OmiseGo or 0x are networks that use Ethereum. Augur and Gnosis are also future market platforms established on this blockchain.
There are also decentralized storage programs like iEx.ec, Storj, etc. Etheremon, My Crypro Heroes, Cryptokitties are also examples of games implemented on a blockchain. Today, several decentralized applications in the cosmetic and pharmaceutical fields are also under development.
