Regarding what constitutes a “smart” contract, one author (in the Georgetown Law Review) defined smart contracts “as agreements where execution is automated, usually by computers.” For example, a smart contract can be formed by a human`s interaction with a vending machine. The human buyer makes a selection by interacting with the vending machine and then pays for the selected goods. The machine computer identifies the selection, receives the payment, verifies that the payment is sufficient for the selection, and then sells the desired product to complete the contract. Finally, smart contracts must be legally adapted to electronic signatures. Some types of contracts cannot be signed electronically, including wills and other probate documents. court orders; health and safety product recall warnings; the documents required for the transport of dangerous goods; notifications of termination of pension benefits; and eviction notices. While oracles are an elegant solution for accessing off-chain resources, this process adds another part with which the parties would have to enter into a contract to enter into a smart contract, somewhat diluting the decentralized benefits of smart contracts. It also introduces a potential “point of failure”. For example, an oracle may detect a system error and be unable to disseminate the necessary information, provide erroneous data, or simply go bankrupt. Smart contracts need to take these eventualities into account before their adoption can be more widespread.
The American Bar Association (ABA) believes smart contracts are a disruptive technology that will change the way individuals do business, manage healthcare, and govern society. Lawyers who want to anticipate these profound changes may want to familiarize themselves with smart contracts and blockchain technology as a whole so that they can effectively communicate this information to their clients. In fact, one of the biggest problems with smart contracts is that they`re notoriously difficult to manage, as they`re nearly impossible to change once implemented — especially since most in-house legal teams don`t have programmers on hand to handle the code. Currently, the input parameters and execution steps of a smart contract must be specific and objective. In other words, if “x” occurs, perform step “y”. Therefore, the actual tasks performed by smart contracts are quite rudimentary, such as automatically moving an amount of cryptocurrency from the wallet from one party to another when certain criteria are met. As blockchain adoption spreads and more assets are tokenized or “chained,” smart contracts are becoming increasingly complex and capable of handling sophisticated transactions. In fact, developers are already chaining several transaction steps together to form more complex smart contracts.
Nevertheless, we are at least many years away from the code being able to establish more subjective legal criteria, such as whether a party meets a standard of economically reasonable expenses or whether an indemnification clause should be triggered and compensation paid. Starting in 2015, UBS experimented with “smart bonds” using the Bitcoin blockchain,[46] in which payment flows could hypothetically be fully automated, creating a self-paying instrument. [47] Szabo`s use of quotation marks around the word “smart” when comparing smart contracts to paper contracts and his renunciation of artificial intelligence are important. Smart contracts may be “smarter” than paper contracts because they can automatically perform certain pre-programmed steps, but they should not be seen as smart tools that can analyze the more subjective requirements of a contract. In fact, the classic example of a smart contract offered by Szabo is a vending machine. Once a buyer has fulfilled the terms of the “contract” (i.e. Throw money into the machine), the machine automatically fills in the terms of the unwritten agreement and delivers the snack. One of the most obvious benefits of a smart legal contract is that the terms of the contract are executed immediately once a condition is met, rather than waiting for a manual approval or fulfillment process to complete the transaction. One solution is for the parties to use a text-based contract where the parameters that trigger the execution of the smart contract are not only visible in the text, but actually fulfill the smart contract. In our example, “less than 32 degrees” would not only be seen in the text, but would also create the parameter in the smart contract itself, minimizing the likelihood of inconsistencies. In addition, courts have established various considerations of fairness to award certain types of violations or to prevent the application of exceptionally onerous clauses.
And if one party causes another party to enter into an agreement through fraudulent acts and representations, the courts may declare the agreement invalid. In other words, courts can iron out the inherent unfairness of unequal bargaining positions, correct minor errors in a written contract, and tailor the agreement to the intended intent of the parties. None of these legal niceties are available in a purely smart contract, where the “code is the law.” Each contract must pay for this computing power by providing “gas” for the transaction. Each step of calculating a contract costs gas for performance. Interaction with a contract usually involves a prepaid amount of gas. While gas is purchased in ethers, the price varies according to demand. To accept a smart contract transaction to be placed in a new block on the blockchain, a cash price for the required gas is submitted with the transaction. The miner can then accept all the transactions he wants to include in his generated block. Similar challenges exist when it comes to terminating a smart contract. Suppose one party discovers an error in an agreement that gives the other party more rights than expected, or concludes that performing its stated obligations will be much more costly than it anticipated.
In a text-based contract, a party may commit or threaten to commit an “actual breach,” that is, knowingly breach a contract and pay the resulting damages if it determines that the cost of performance is greater than the damage it owes. In addition, by suspending or threatening to do so, one party may bring the other party back to the negotiating table to negotiate an amicable solution. Smart contracts do not yet offer analogue self-help measures. In most cases, a discussion of “smart contracts” focuses on automated agreements implemented at least partially by programming on a blockchain. Although the broadest definition of a smart contract includes operating a vending machine, smart contracts are less attractive to vending machines because they rely heavily on trust. The concept of trust means that a person must have knowledge about a machine before being ready to enter into a smart contract with that machine. For example, a person who wants to buy a new iPhone from a vending machine may be willing to do so when approaching that vending machine: are you looking for a more humane way to automate your contracts?
