Legal Aspects of Smart Contracts and Regulation in Spain

1.- What are Smart Contracts:

Increasingly, technology neophytes are hearing the term “Smart Contracts” used. However, the use of Smart Contracts should not be seen as a substitute for all traditional contracts. Only in some cases, and we will look at ten examples below, are Smart Contracts really operational.

2.- Why can’t Smart Contracts replace all traditional contracts even today?

1. 1. As we say, smart contracts have the potential to revolutionise the way contracts are made. However, there are still a number of reasons why they cannot replace all traditional contracts.
   2. Smart contracts are inflexible. Smart contracts are encoded in a blockchain, which means that they cannot be easily modified. This can be a problem if circumstances change or if an update is needed. Traditional contracts, on the other hand, are more flexible and can be modified as needed.
   3. Smart contracts are not compatible with all legislation. Smart contracts are not yet regulated in many countries. This means that there may be uncertainty about their legal validity. Traditional contracts, on the other hand, are regulated by local laws.
   4. Smart contracts are not suitable for all types of agreements. Smart contracts are best suited for simple, well-defined agreements. Agreements that are complex or require human interpretation may be difficult to codify in a smart contract. Traditional contracts, on the other hand, can be used for any type of agreement.

Despite these limitations, smart contracts have the potential to revolutionise the way contracts are made. As blockchain technology continues to develop, smart contracts are likely to become more flexible, legally compliant and suitable for a wider range of agreements.

3.- What are Smart Contracts?

Smart contracts are autonomous computer programmes that are automatically executed when predefined conditions in a digital agreement are met. These contracts are designed to facilitate, verify or enforce the execution of a contract or agreement without the need for human intermediaries.

4.- How they work in the digital environment:

1. Programming: A smart contract is created by programming a set of rules and conditions that must be met for the contract to be activated.
2. Digital Agreement: All parties involved in the contract agree on the conditions and terms of the contract, and these are codified in the smart contract.
3. Automated Execution: Once predefined conditions are met, the contract is automatically executed. For example, if it is a payment contract, when a certain amount of cryptocurrencies is received, the contract automatically releases the funds to the recipient.
4. Blockchain: Smart contracts are usually executed on a blockchain platform, which ensures transparency and immutability of transactions. The execution of the contract is recorded in a decentralised registry.
5. No Intermediaries Required: One of the key features of smart contracts is that they do not require intermediaries, such as notaries or lawyers, to verify or enforce the contract. This can reduce costs and speed up the enforcement process.

5.- Parties to Smart Contracts:

In a smart contract, the parties involved are the same as in a traditional contract:

1. Party A: Represents a party that agrees to the terms of the contract and benefits from its performance. For example, it can be a person, a company or an entity.
2. Party B: Represents the other party to the contract, who also agrees to the terms and will benefit from their performance.
3. Contract: The contract itself is a programmed digital entity that acts as an automatic arbiter and ensures that conditions are met and actions are executed when requirements are met.

The parties to a smart contract can be individuals, companies or organisations that agree on the conditions and terms of the contract and then use smart contract technology to ensure that they are automatically fulfilled.

6.- Legal Validity in Spain:

Exploration of the legal validity of smart contracts in Spain and their recognition as valid means for agreements.

1. 1. Legal recognition: Spanish law does not prohibit smart contracts and recognises their validity in principle. In legal terms, a contract can be valid as long as it complies with the essential requirements of contract formation, regardless of whether it is concluded in the traditional way or using smart contract technology.
   2. Regulatory Compliance: Smart contracts must comply with existing regulations and laws, such as the Spanish Civil Code. The conditions and terms of the contracts must be clear, and the parties must agree on them. In addition, transactions involving cryptocurrencies or other digital assets may be subject to specific regulations according to their nature.

7.- Liability and Enforcement:

Consideration of who is responsible if a smart contract does not work as expected and how contracts are enforced in case of dispute.

Liability in the event that a smart contract does not perform as expected and how contracts are enforced in the event of a dispute may depend on a number of factors, such as the specific circumstances of the contract, local regulations and jurisdiction. Some general considerations are described below:

1. Responsibility for Programming Errors: If a smart contract does not work as intended due to programming errors or incorrect code, the responsibility lies with the developer or entity that created the smart contract. Errors in the code may be considered a breach of contract and may require the developer to correct the error or provide a solution.
2. Automatic Execution: Smart contracts are automatically executed when predefined conditions are met. If all conditions are met, the contract will be executed as scheduled without human intervention. This can reduce the risk of non-compliance due to third party intervention.
3. Verification of Data and Oracles: Some smart contracts may rely on external data or information sources called “oracles”. If the data source or oracle provides incorrect information, there may be disputes about the performance of the contract. In such cases, the parties may turn to the data source or oracle to address the dispute.

Examples of Oracles:

1. Cryptocurrency Price Oracles: These oracles provide real-time data on the prices of cryptocurrencies, such as Bitcoin, Ethereum and other digital assets. Smart contracts can use this information to perform calculations, trigger financial contracts or execute transactions based on changes in cryptocurrency prices.
2. Weather Data Oracles: Weather data oracles provide information on weather and climate conditions in specific locations. Smart contracts can use this data to trigger contracts related to insurance, agricultural contracts or weather-dependent logistics.
3. Financial Data Oracles: These oracles provide information about financial indices, interest rates, exchange rates and other financial data. Smart contracts can use this information to automate payments, manage financial derivatives or take other financial actions based on changes in financial markets.

8.- Ten examples where Smart Contracts are operational today.

1. Financial transactions: Smart contracts can be used to automate financial transactions, such as payments, fund transfers and loans. For example, a smart contract could be used to secure a mortgage loan, releasing funds to the borrower once the terms of the loan have been met. Good examples of such contracts are ISDAs or CMOFs.

2. Insurance: Smart contracts can be used to automate insurance claims. For example, a smart contract could be used to verify whether a claim complies with the terms of the policy and pay out the claim to the insured automatically.
3. Supply chains: Smart contracts can be used to track the movement of goods along a supply chain. For example, a smart contract could be used to confirm receipt of a shipment, which could trigger payment to the supplier.
4. Voting: Smart contracts can be used to create more secure and transparent voting systems. For example, a smart contract could be used to verify the identity of voters and ensure that each vote is counted only once.
5. Intellectual property rights: Smart contracts can be used to register and manage intellectual property rights. For example, a smart contract could be used to register a patent or copyright, which could help owners protect their assets.
6. Energy management: Smart contracts can be used to automate energy transactions. For example, a smart contract could be used to automatically buy and sell energy in a decentralised energy market.
7. Internet of Things: Smart contracts can be used to connect smart devices and automate tasks. For example, a smart contract could be used to control access to a building or manage the energy consumption of a smart home.
8. Government: Smart contracts can be used to automate government processes. For example, a smart contract could be used to issue building permits or manage the distribution of social benefits.
9. Education: Smart contracts can be used to create more personalised and efficient learning systems. For example, a smart contract could be used to assign homework and grade papers, which could help students learn at their own pace.
10. Healthcare: Smart contracts can be used to manage healthcare. For example, a smart contract could be used to book appointments with doctors or manage the distribution of medicines.

9.- Dispute Resolution and Jurisdiction:

In the event of a dispute over the execution of a smart contract, the parties may have recourse to dispute resolution mechanisms, which may include mediation, arbitration or the court system. The applicable jurisdiction and legal framework may vary depending on the contract and the location of the parties involved.

10.- Transparency of the Blockchain:

Most smart contracts are executed on blockchains, which provide a transparent and immutable record of all transactions. This can serve as evidence in the event of a dispute and help determine which parties fulfilled their contractual obligations.

11.- Supplemental Contracts:

In some cases, the parties may enter into supplemental contracts or legal agreements outside the smart contract to address specific compliance, liability and dispute resolution issues.

12.- Specific Regulation:

Mention of any specific regulation related to smart contracts that has been introduced in Spain or in the European Union.
