Frequently Asked Questions

What are smart contracts and how do they work?

Smart contracts are computer code stored on a blockchain that automatically execute all or parts of an agreement. They can either be the sole manifestation of an agreement or complement a traditional contract. The code is replicated across multiple nodes of a blockchain, ensuring security, permanence, and immutability. Smart contracts are written in programming languages like Solidity and require specific and objective input parameters and execution steps. They work by following “if/when…then…” statements written into code on a blockchain. A network of computers executes the actions when conditions are met and verified. The blockchain is then updated, and the transaction cannot be changed. Only parties with permission can see the results.

What are the limitations of smart contracts?

While smart contracts offer benefits such as automation, efficiency, and reduced costs, they are not yet capable of determining subjective legal criteria. This means that they cannot handle complex transactions that involve subjective judgments or legal interpretations. Smart contracts are best suited for automatically executing payment of funds upon triggering events and imposing financial penalties if certain conditions are not met. They eliminate the need for human intervention and reduce execution and enforcement costs.

What role does blockchain play in smart contracts?

Blockchain technology provides the foundation for smart contracts. The decentralized and distributed nature of a blockchain ensures security, permanence, and immutability of smart contract code. Blockchain transaction records are encrypted and connected to previous and subsequent records, making them difficult to hack. Smart contracts leverage the transparency and tamper-proof nature of a blockchain to automate the execution of agreements and eliminate the need for intermediaries.

How can smart contracts be executed on a blockchain?

Before a smart contract can be executed on certain blockchains, a transaction fee known as “gas” must be paid. Gas acts as a gate to prevent overly complex or numerous smart contracts from overwhelming the blockchain. Once the fee is paid, the smart contract code is processed by a network of computers known as the Ethereum Virtual Machine (EVM). The EVM executes the code according to the specified conditions, updating the blockchain and making the transaction irreversible.

Are there online tools available for creating smart contracts?

Yes, there are online tools provided by organizations that allow individuals and businesses to create smart contracts. These tools typically offer user-friendly interfaces and templates that simplify the process of programming smart contracts. They enable anyone, regardless of coding expertise, to create and deploy smart contracts on a blockchain. These online tools contribute to the adoption of blockchain technology by making it more accessible and user-friendly.

How are smart contracts being used in commercial contexts?

Smart contracts have found applications in various industries and commercial contexts. For example, businesses like Sonoco and IBM are using smart contracts on a blockchain to track pharmaceuticals in the supply chain, ensuring transparency and authenticity. The Home Depot resolves disputes with vendors using smart contracts, eliminating the need for centralized arbitration authorities. Companies are also joining platforms like, a blockchain-based platform for global trade, to streamline trade finance processes, reduce friction and risk, and expand trade opportunities.
