Blockchain Smart Contracts For Smart Supply Chains

Smart contracts are defined as the programs that are stored on a Blockchain. It is run on various predefined conditions. The term sound more like a legal instrument but a smart contract is just a computer program responsible for performing different tasks. It works by a set of processes that enables the smart contract to live on Blockchain. Smart contracts are the programs that are stored on a Blockchain and are executed based on an agreement.  Smart contracts have the potential to improve supply chain efficiency but there is a significant risk that the coder will set them up incorrectly or that they won’t take into account a change in circumstances. Businesses interested in using smart contracts must carefully consider the advantages and disadvantages to divide the associated risks among the parties in the smart contract.

What are Blockchain Smart Contracts? 

Smart contracts are digital contracts between parties to a transaction that is written in computer code and distributed to the blockchain, which will execute themselves. Through automated verification and execution of the numerous business transactions involved, they lessen complexity in a supply chain. A supply chain can become more agile and transparent, traceable, and efficient thanks to smart contracts, which can improve stakeholder relationships. The program makes the contract smart by enabling digital enforcement, facilitation, and verification. As a result, the contract will operate exactly as it has been programmed, eliminating the possibility of fraud or other intervention. Similar to the blockchain, a smart contract accepts data from a ledger and, when necessary, can cause an event. For instance, the smart contract may start a delivery if a payment has been received, but it may also start a penalty or another action if a condition has not been met.

How do Smart Contracts Work?

The Smart works by following simple codes like “if/then…. when.” in a given statement on a Blockchain. These codes are decoded by networks of computers that are responsible to execute these actions. So, the actions here relate to releasing funds, sending notifications, registering a vehicle, etc. So, the Blockchain is refreshed and updated as soon as the transaction is completed. Thus, the transactions can’t be changed with limited parties having permission to look for the results.  There are many conditions as are required to reassure the participants that the activity will be accomplished and can be included in a smart contract. Participants are required to agree on the “if/when…then” rules as they govern those transactions, consider any potential exceptions, and design a framework for resolving disputes. Hence to set the terms, the participants must also decide on how transactions and their data are represented on the blockchain.

Benefits of Smart Contracts 

  • Speed, efficiency, and accuracy: 
As the condition is met and the contract is executed then the same, the contracts are digital and automated. Moreover, there is no paperwork or time required.  
  • Transparency and trust: As there is no third party involved and no encrypted records of transactions are shared. So, there are not many questions about the information. 
  • Security: The blockchain transaction records are encrypted. So, they are incredibly difficult to hack. Additionally, hackers would need to alter the entire chain to change a single record on a distributed ledger. 
  • Savings: Smart contracts can manage the intermediaries’ needs and also transactions. By extension, the associated fees and time are also delayed. 

Use of Blockchain Smart Contracts for Smart Supply Chains 

Supply chains, industries, and ecosystems can all be transformed by blockchain. For all industries, including those that might initially appear to profit less, there are countless chances. As you can expect, supply chains undergo alteration over time. As one technology might only have an impact on one or two sectors of a supply chain, supply chain transformation can take some time. The manual management of paperwork can cause expensive delays and waste, which smart contracts can assist to prevent. From there, the door is open to a supply chain that is from one end to the other smarter, quicker, and more secure. The successful implementation of smart contracts in the smart supply chains needs a proper framework for smooth functioning and implementation of Blockchains. It includes legal protection to the technology and also measures the rights management information. So smart contracts are like algorithmic account owners on a Blockchain. Also, Smart contracts cannot check on the non-coder aspect and read how the smart contract works. The programmer can easily code the smart contract, even if the parties have a traditional text-based agreement. 


To execute and enforce underlying legal contracts, smart contracts were developed using distributed database technologies like blockchain. They are made to carry out self-enforcing contractual requirements, such as payments and legal duties, without the assistance of an already-existing, reliable third party. By implementing traceable and irreversible transactions, smart contracts aim to lower transaction and enforcement costs.
