Developers have just recently begun to delve into the breadth of capabilities provided by smart contracts, which underpin blockchain technology. The number of applications for this technology is rapidly expanding. Many people see opportunities in new areas where traditional contracts now govern transactions. There are no limits to the use of these contracts.
A smart contract is a self-executing contract. In this contract, the conditions of the buyer-seller agreement are put directly into lines of code. The code, as well as the deals it contains, are disseminated throughout a decentralized blockchain network. Transactions are trackable and irreversible, and the programming regulates their execution.
Today, at Bitunivex, we have prepared a comprehensive article on smart contracts just for you. So, please keep reading to discover what smart contracts are and how they are shaping the future.
What is a smart contract?
“Smart contracts” refers to computer code that automatically executes all or portions of a contract. This contract is stored on a blockchain-based platform. The code can be the sole representation of the parties’ agreement.
However, it can also supplement a standard text-based contract by carrying out specific clauses, such as transferring funds from Party A to Party B. As the code is duplicated over numerous blockchain nodes, it benefits from its security, permanence, and immutability.
The replication also implies that the code gets performed as each new block is added to the network. Suppose the parties have signalled that specific parameters have been satisfied by commencing a transaction.
In that case, the code will perform the step triggered by those parameters. The code will not take action if no such transaction has been started. It is also worth mentioning that most smart contracts are written in Solidity. Solidity is the programming language designed explicitly for such computer systems.
How does a smart contract work?
At the moment, a smart contract’s input parameters and execution phases must be precise and objective. In other words, if “x” happens, go to step “y.” As a result, the actual functions of smart contracts are rather basic.
These functions include automatically transmitting a specific amount of bitcoin from one party’s wallet to another when specific criteria are met. Smart contracts will grow more complicated and capable of managing sophisticated transactions as blockchain use increases and more assets are tokenized or “on-chain.” Developers are already combining numerous transaction processes to create more complicated smart contracts.
However, the code cannot yet analyze more subjective legal criteria. For example, whether a party made commercially reasonable efforts or if an indemnifications clause should be activated and the indemnity paid.
An extra step is necessary before the system can perform a built smart contract on certain blockchains. For instance, the payment for the contract transaction fee should be added to the chain and run on.
These contracts operate on the Ethereum Virtual Machine (EVM) on the Ethereum blockchain. This payment is known as “gas”. The more complicated the smart contract (depending on the transaction processes to be completed), the more gas will be required to execute it.
As a result, gas presently serves as a key barrier to prevent the EVM from becoming overwhelmed by excessively sophisticated or many contracts.
These contracts are now best adapted to automate two sorts of “transactions” featured in many contracts.
- Assuring the payment of funds upon the occurrence of specified triggering events.
- Imposing financial penalties if specific objective requirements are not met.
Human intervention, such as a trustworthy escrow holder or even the legal system, is unnecessary once the smart contract is launched and operational in each case. This automaton will decrease the contracting process’ execution and enforcement costs.
Smart contracts might reduce so-called procure-to-pay gaps. When a product is delivered to a warehouse and scanned, this contract might quickly request the necessary approvals. Once granted, send payments from the buyer to the seller. Sellers would get paid faster and no longer have to participate in dunning. Simultaneously, purchasers’ account payable fees would be decreased.
As a result, this might influence working capital requirements and make financial operations easier for both parties. On the enforcement side, if a payment is not successful, a smart contract could be set up to prohibit access to an internet-connected item. For instance, access to particular material may be automatically prohibited if payment is not received.
Smart contract: roots and history
Nick Szabo, a computer scientist, and cryptographer came up with the term “smart contract”. He was a doctoral student at the University of Washington approximately at that time.
According to Szabo, the digital revolution enabled the development of new organizations and new techniques to codify the ties that constitute these institutions. We call these new contracts “smart” because they are significantly more useful than their paper-based predecessors.
Artificial intelligence is not mentioned. A smart contract is a collection of promises stated in digital form and the protocols that the parties use to fulfil these promises.
When comparing these contracts to paper-based contracts, Szabo’s usage of quotes around the word “smart” and his rejection of artificial intelligence are significant. These contracts are “smarter” than paper contracts in many ways.
They can perform specific pre-programmed actions automatically. However, they should not be viewed as sentient instruments capable of parsing a contract’s more subjective criteria. A vending machine is, in fact, Szabo’s basic illustration of a smart contract. When a customer meets the “contract” criteria (i.e., entering money into the machine), the system automatically follows the unwritten agreement and provides the snack.
Ricardian Contracts, according to Grigg, are a bridge between text contracts and code. These types of contracts have the following characteristics: a single document that is
- Offered by an issuer to holders.
- For a valuable right held by holders, and managed by the issuer.
- Easily readable by people.
- Readable by programs.
- Digitally signed.
- Carries the keys and server information
- Allied with a unique and secure identifier.
Smart contract promises are constructed using “if-then” clauses, prevalent in computer programming. Nick Szabo initially used the vending machine to demonstrate smart contract processes. This machine is the greatest real-world illustration of if-then functionality. If you put $1 into the machine, it will give you a snack.
The entire transaction is pre-determined by the machine’s programming (human or institutional) without any outside influences. These contracts are meant to execute operations independently in the same way.
Smart vs. traditional contracts
These contracts are self-executing contracts written in computer codes that are most commonly seen in applications created on blockchain platforms like Ethereum. Pitfalls of these contracts are as follows:
- The inability to account for subjectivity.
- A high threshold for improvement based on community consensus.
- The lack of a direct means to incorporate real-world data in a trustless manner.
On the other hand, These contracts offer another benefit. The advantages of being both immutable and trustless compared to traditional contracts. A smart contract is a robust tool with various possible uses that save resources, money, and time.
A contract is traditionally an agreement between two or more people to trade promises and services, and it frequently has numerous sections. A promise, such as a monetary payment, can be swapped for another promise or service.
Furthermore, several contract provisions, such as the date of the exchange and the situations in which the contract becomes void, might affect the trade. These particulars are why some of the most typical contracts, such as those establishing loan and employment conditions, are so lengthy.
Do smart contracts need lawyers and other mediators?
Lawyers are frequently required for two reasons. First, we need attorneys to draft the contract’s text. And second, we need them to guarantee that the contract is carried out correctly. When a contract is broken, a judge, a courtroom, and other expensive resources are frequently required. Escrow, a third party that holds the cash until both parties complete the agreed-upon requirements, is commonly used in significant financial transactions like buying a property.
The mediators and resources needed to form legally enforceable agreements come at a cost. Not to mention the faith you must place in these organizations to do their jobs correctly. Furthermore, because every resource utilized in these circumstances consumes time, contracts might take days or weeks to complete.
Because of these qualities, smart contracts do not rely on many of the same assumptions and needs as traditional contracts.
Once a smart contract is created and performed, one cannot change it. Therefore, it’s permanent. Because nodes, or computers that administer the blockchain, each maintain an identical copy of the contract. Any changes to the contract are impossible without network consensus. So, smart contracts are immutable.
Each smart contract is self-sufficient, which means it doesn’t rely on third parties to carry out its functions, such as attorneys and financial institutions. Without external trust, removing external influence implies that one can expect the same result every time. As a result, even the most complex transactions can be performed in seconds or minutes rather than hours or days. So, removing external influence means smart contracts are trustless.
Smart contracts also eliminate the need to pay, trust, or wait for third parties to perform them, making them a more appealing contract.
Are Smart Contracts Enforceable in Australia?
One of the challenges in talking about these contracts is that the phrase describes two quite distinct concepts. The first concerns smart contracts that are established and implemented without the support of a legally binding text-based contract. For example, two parties may come to an oral agreement on the business relationship they wish to document and then convert that agreement into executable code.
A smart contract that is legally enforceable must nevertheless fulfill all of the traditional characteristics of a contractual contract. Despite being theoretically unstoppable in the digital world, any coercion, undue influence, or unethical conduct might make a smart contract unlawful at law. The name of the other contracting party and whether or not that person has the legal ability to engage in the contract are frequently unclear. A smart contract controversy has yet to be resolved in Australian courts.
When a smart contract conflict emerges, it might not be easy to ascertain who is responsible. First, the identity of a smart contract’s authors may not be known or determined. Especially in an open-source scenario where several parties have updated the code.
Third, there are further identification difficulties when the smart contract incorporates a new type of organization known as a “Decentralised Autonomous Organization” (DAO). Because the essence of these new organizations is that participants do not have to identify themselves. The DAO’s link between these persons is likewise unknown. While no legal definition of a DAO has been established, it may be a partnership or joint venture.
Suppose a smart contract runs in an unanticipated way or has a fault that is exploited. In that case, the smart contract creators, generally developers and attorneys, will invariably be prospective candidates for lawsuits.
Subjectivity is one of the current limitations of smart contracts. The usefulness of smart contracts is constrained by the code they contain. It’s tough to include subjectivity or the requirement for flexibility into a contract’s design if there’s any.
Making changes takes much effort when it comes to smart contracts. If the code has defects or loopholes, altering the contract takes many endeavors from the community and unanimous consent from the network’s nodes.
Moreover, smart contracts sometimes need the usage of real-world data to execute, such as knowing the worth of the US dollar, a stock price, or the position of a product being sent throughout the world.
Smart contracts are thought to be quick, efficient, and accurate. When a condition is satisfied, the contract is instantly executed. Because smart contracts are digital and computerized, there is no paperwork to deal with and no time wasted correcting errors that might occur when filling out documentation by hand.
Another advantage of smart contracts is their trust and transparency. There’s no need to worry about information being tampered with for personal gain because there’s no third party engaged, and everyone in the network would have a copy of encrypted transaction logs.
Furthermore, smart contracts offer security as an additional benefit. Since blockchain transaction records are encrypted, they are extremely difficult to hack. Again, because each record on a distributed ledger is linked to the preceding and subsequent entries, hackers would have to modify the entire chain to change a single record.
Smart contracts are also cheaper. These contracts eliminate the need for mediators to conduct transactions and the time delays and fees that come with them.
Future of smart contracts
Smart contract code is not smart enough to prevent allegations of misrepresentation, misleading and deceptive behaviour, irresponsible coding or security vulnerabilities, or government regulation. We will always need attorneys to advise and resolve conflicts in some cases of smart contract issues.
While third parties frequently give this information, oracle technology (such as Chainlink or Band Protocol) uses off-chain data to bring this information onto the blockchain.
Yet, one of the most significant obstacles to clever contract formulation and conflict resolution is the legal profession’s lack of technology literacy. Lawyers with real-world coding and software development skills are hard to come by, and those who understand blockchain technology and installations are even harder to find. Lawyers should do their best to understand how blockchain technology and smart contracts function and how they are implemented and developed.
These efforts should continue until artificial intelligence working with smart contract code replaces attorneys. But, above all, attorneys must recognize their technical limits and seek expert assistance when necessary.
