Legal and regulatory uncertainty: The legal status of smart contracts varies across jurisdictions, which may impact their enforceability and create challenges for cross-border transactions.
Limited flexibility: Smart contracts are deterministic and cannot accommodate unforeseen changes in circumstances or adapt to new information without manual intervention.

Components of Smart Contracts

A. Contract parties

Smart contracts involve two or more parties who agree to the terms and conditions outlined in the contract. The parties are usually represented by their respective blockchain addresses, which serve as their digital identities.

B. Contract terms and conditions

The terms and conditions of a smart contract are encoded as computer code, typically using a programming language like Solidity (for Ethereum-based smart contracts) or Bitcoin Script (for Bitcoin-based smart contracts). This code defines the rules, obligations, and conditions that govern the contract’s execution.

C. Digital signatures and encryption

Smart contracts rely on cryptography to ensure the authenticity and integrity of transactions. Parties digitally sign transactions using their private keys, which are then verified by the network using the corresponding public keys. This process ensures that only authorized parties can initiate transactions and prevents tampering or forgery.

D. Oracles and data inputs

Oracles are external data sources that provide information to smart contracts, enabling them to interact with the outside world. They can be used to obtain real-time data, such as stock prices or weather conditions, which may influence the execution of a smart contract.

However, reliance on oracles introduces potential security risks and trust issues, as the accuracy and reliability of the provided data are crucial for the proper functioning of the smart contract.

E. Execution and settlement

Once the predefined conditions are met, the smart contract automatically executes the agreed-upon actions, such as transferring funds or updating a ledger. The execution is transparent and irreversible, ensuring that all parties adhere to the terms of the agreement.

Settlement occurs directly between the parties involved, without the need for intermediaries, which can significantly reduce transaction costs and time.
