Smart Contracts Blockchain Development and Benefits

Smart contracts are self-executing contracts with the terms of the agreement between buyer and seller being directly written into lines of code. The code and the agreements contained therein are stored and replicated on a blockchain network.

Smart contracts have the potential to revolutionize the way that transactions are carried out, as they can facilitate, verify, and enforce the negotiation or performance of a contract. Some potential benefits of using smart contracts in a blockchain include:

  • Automation: Smart contracts can automatically execute the terms of a contract once certain conditions are met, without the need for manual intervention.
  • Accuracy: Because smart contracts are stored on a blockchain and are secured using cryptography, they can be trusted to accurately reflect the terms of an agreement.
  • Efficiency: By automating contract execution and eliminating the need for intermediaries, smart contracts can significantly streamline and speed up the process of completing a transaction.
  • Transparency: All parties can view and verify the terms of a smart contract on a blockchain, which can help to build trust and increase transparency.
  • Security: The decentralized nature of blockchain technology and the use of cryptographic hashes make smart contracts highly secure and resistant to tampering.

Overall, the use of smart contracts in a blockchain can help to increase the efficiency, accuracy, and security of transactions, while also reducing the need for intermediaries and increasing transparency.

Benefits of smart contracts

Speed, efficiency, and accuracy

with smart contracts, once a condition is met it gets executed immediately since they are digital and automated. There is no paperwork involved hence minimal errors are encountered saving time correcting errors.

Transparency and Trust

Trust is high since there is no third party involved in the execution of the smart contract. For Transparency, all encrypted records of any transaction done are always shared among participants hence one can easily follow up for self and reconcile.


Changing a single record by hackers is impossible as the record is interconnected with previous records in a distributed ledger meaning for them to succeed they need to make changes to the entire chain, besides that also all the records through the smart contracts are always encrypted


Smart Contracts do not need intermediaries for any transaction to be conducted hence saving time and eliminating any other fee that could have been added when those parties were involved

Smart Contracts Application Areas

Here are some potential application areas for smart contracts:

  1. Supply chain management: Smart contracts can be used to automate and streamline the process of tracking goods as they move through the supply chain.
  2. Real estate: Smart contracts can be used to facilitate the buying and selling of real estate, including the transfer of ownership and payment of taxes and fees.
  3. Financial services: Smart contracts can be used to automate financial transactions, such as the issuance and trading of financial instruments.
  4. Healthcare: Smart contracts can be used to securely and automatically manage the exchange of medical records and other healthcare-related data.
  5. Government: Smart contracts can be used to automate the process of issuing and tracking government-issued documents, such as licenses and permits.
  6. Intellectual property: Smart contracts can be used to automate the licensing and royalty payment process for intellectual property, such as software, music, and artwork.
  7. Identity verification: Smart contracts can be used to create a decentralized system for verifying identity, allowing individuals to control and share their personal information as needed.

These are just a few examples of the potential application areas for smart contracts. As the technology continues to evolve, it is likely that smart contracts will be used in a wide range of other industries and contexts.

Here is a simple example of a smart contract:

<code>contract SimpleContract {
  address public owner;

  constructor() public {
    owner = msg.sender;

  function transferOwnership(address newOwner) public {
    require(msg.sender == owner);
    owner = newOwner;

This smart contract defines a contract called “SimpleContract” with a single function called “transferOwnership.” The function allows the owner of the contract to transfer ownership to a new address by providing the new owner’s address as an input. The function includes a “require” statement that checks that the message sender (i.e., the person calling the function) is the current owner of the contract. If the message sender is not the owner, the function will not execute.

This is a very simple example of a smart contract, but it illustrates the basic concept of a self-executing contract with terms written in code that is enforced by the blockchain. In practice, smart contracts can be much more complex and can include a wide range of functions and conditions.
