Smart contracts are self-executing digital contracts that allow the automatic execution of predefined terms and conditions when certain predetermined conditions are met. They are computer programs that run on blockchain technology, which is a decentralized ledger that allows for secure and transparent transactions without the need for a middleman.
Its designed to enforce the rules and regulations of a contract without the need for human intervention, ensuring that the terms of the agreement are met without any ambiguity or misunderstanding. They can be used to automate various types of transactions, including financial transactions, supply chain management, real estate, and more.
Smart contracts are written in programming languages and are stored on a blockchain, which makes them immutable and tamper-proof. Once a smart contract is deployed, it cannot be modified, making them an ideal solution for applications where trust and transparency are critical.

Overview of Smart Contracts – Revolutionizing the Way We Conduct Business
Overall, smart contract have the potential to revolutionize the way we conduct business by providing a secure and transparent way to execute contracts automatically without the need for intermediaries, reducing costs, and increasing efficiency.
Smart contracts mean different things depending on the blockchain platform. Ethereum smart contract is short computer programs that are stored on Ethereum’s blockchain, replicated across all the nodes, and are available for anyone to inspect. There are two steps that are performed separately:
- Uploading the smart contract to Ethereum’s blockchain
- Making the smart contract run
You upload a smart contract by sending the code to miners in a special transaction. If the transaction is successfully processed, the smart contract will then exist at a specific address on Ethereum’s blockchain.
You may then make it run by creating a transaction that says ‘Please run the smart contract found at address x’.
Example of a basic smart contract
Here is an example of a basic smart contract. It creates a token called ‘GavCoin’ that initially issues 1 million GavCoins to the creator of the smart contract, and then allows them to send GavCoins to other users:
For a real example of a smart contract, the smart contract that holds the balances of the Indorse ICO tokens can be found at address 0xf8e386eda857484f5a12e4b5daa9984e06e73705.
Once a contract has been uploaded, it behaves a bit like a jukebox. When you want to run it, you create a transaction pointing to the contract and supply whatever information the contract expects. You pay gas to the miner to run it. As part of the mining process, each miner will execute the transaction, which involves running the smart contract.
The miner who successfully wins the proof-of-work challenge will publish the winning block to the rest of the network. The other nodes will validate the block, add the block to their own blockchains, and process the transactions, including running the smart contract. This is how Ethereum’s blockchain gets updated, and how the state of the EVMs on each node’s machine is synchronised.
Ethereum smart contracts are described, ‘Turing complete’. This means that they are fully functional and can perform any computation that can be done in any other programming language.
Enforcing ‘Code is Law’ for Secure and Transparent Contract Execution
Smart contracts are a great example of how the expression “code is law” can be applied in a practical setting. Smart contracts are self-executing computer programs that run on blockchain technology, which allows for secure and transparent transactions without the need for intermediaries.
The terms and conditions of the smart contract are written in code and are automatically enforced when certain predetermined conditions are met. This means that the rules and regulations of the contract are enforced by the code itself, without the need for human intervention. The code is the law, and it ensures that the contract is executed in a transparent and secure manner, without any ambiguity or misunderstanding.
The use of smart contracts can significantly reduce the cost and time associated with traditional contract management, as well as reducing the risk of fraud or errors. Smart contracts are tamper-proof, meaning that once deployed, they cannot be modified or tampered with, making them an ideal solution for applications where trust and transparency are critical.
Overall, the use of smart contract provides a practical application of the expression “code is law,” as it demonstrates how computer code can be used to enforce rules and regulations, providing a more efficient, secure, and transparent way to execute contracts.
Smart Contracts languages: Solidity / Serpent, LLL (Lisp Like Language)
The most common language that Ethereum smart contracts are written in is Solidity. Serpent and LLL can also be used. Smart contracts written in these languages will all compile and run on Ethereum Virtual Machines.
• Solidity is similar to the language JavaScript. This is currently the most popular and functional smart contract scripting language.
• Serpent is similar to the language Python and was popular in the early history of Ethereum.• LLL is similar to Lisp and was used mainly in the very early days only. It is probably the hardest to write in.
Ethereum software: geth, eth, pyethapp
The three official Ethereum clients (full node software) are open source, allowing you to view and customize their code. They include geth (written in Go), eth (written in C++), and pyethapp (written in Python).
These are all command-line based programs (think green text on black backgrounds) and so additional software can be used for a nicer graphical interface. Currently, the most popular graphical interface is Mist (https://github.com/Ethereum/mist), which runs on top of geth or eth.
So, geth/eth does the background stuff, and Mist is the pretty screen on top.
Currently the most popular Ethereum clients are geth and Parity. Parity is Ethereum software built by a company called Parity Technologies. It is also open source and is developed in the Rust programming language.
Beyond Ethereum: Exploring the Best Use Cases of Smart Contract
Smart contracts have become immensely popular in recent years, primarily because of their association with the Ethereum blockchain. However, blockchain contracts have applications beyond just Ethereum. In this article, we will explore some of the best use cases of smart contracts beyond the Ethereum blockchain.
-
Supply Chain Management blockchain contracts can be used to manage supply chains efficiently. These contracts can automate the purchasing process, verify the authenticity of products, and track the inventory in real-time. This automation can reduce the risk of human error, cut down on paperwork, and accelerate the process of getting products into the market.
-
Real Estate The use of smart contracts in real estate can revolutionize the way we buy and sell property. Blockchain contracts can be programmed to handle the entire process of buying and selling a property, including the transfer of ownership, payment, and the disbursement of funds to all parties involved.
-
Healthcare Smart contracts can be used in healthcare to manage patient data, automate billing processes, and facilitate the transfer of medical records between healthcare providers. Blockchain contracts can ensure that patient data is securely stored on the blockchain, reducing the risk of data breaches.
Another Use Cases of Smart Contract
-
Insurance Smart contracts can be used to automate the insurance payout process. These contracts can be programmed to automatically pay out a claim based on certain predetermined conditions, such as a natural disaster or an accident. This automation can reduce the time it takes to receive payouts and minimize the potential for fraud.
-
Gaming Smart contracts can be used to create decentralized gaming platforms that are transparent and secure. These platforms can use blockchain contracts to ensure that all players have access to fair and random gameplay, and that there is no chance of manipulation or fraud.
In conclusion, smart contracts can be used in a variety of industries to automate processes, reduce costs, and increase efficiency. While Ethereum is the most popular blockchain for smart contracts, other blockchains such as EOS and TRON are also exploring the use of smart contracts. The possibilities of smart contracts are endless, and we are only just beginning to scratch the surface of what this technology can do.
