Smart contracts (also referred to as cryptocontracts) are computer programs which, under specific conditions, automatically and directly regulate the transfer of digital assets between parties in accordance with an agreed upon plan. Smart contracts differ from traditional contracts in that they incorporate automated enforcement features into them, with programs known as smart contracts operating precisely according to what their developers configured, coded and programmed them for. Smart contracts are legally-binding agreements enforced through code rather than law, much like conventional contracts are.
Nick Szabo first proposed using blockchain-powered decentralized ledgers for smart contracts back in 1994. According to this theory, these smart contracts could potentially consist of written code which could then be stored and replicated across its network of connected computers in order to form contracts that may then be stored and replicated securely via smart contract technologies like this blockchain ledger.
What Is A Smart Contract?
"Smart contracts" refers to Ethereum blockchain programs with multiple functions stored at specific addresses on their blockchains, where data (its state) and code (its functions) is maintained within them.
Ethereum accounts exist in the form of smart contracts, meaning they can serve as objects for transactions and have balances that must be managed, yet instead are installed onto the network to operate according to instructions set out on them. Users interact with them by submitting transactions carrying out functions specified on them - similar to traditional contracts but with additional code enforcement capabilities - that execute them irreversibly and are indestructible by default.
How Do Ethereum Smart Contracts Work?
Smart contracts are programs that, under specific conditions, automatically execute transactions without needing middleman services to carry them out. While Ethereum was developed specifically to accommodate smart contracts, their concept extends far beyond this blockchain network or platform.
No matter their visibility or not, middlemen play an ever-present role in our digital lives. A central authority such as Facebook or Twitter must exist for even simple online tasks like sharing cat photos among friends - they both maintain and enforce rules on our networks. Luckily smart contracts make these processes automated without the need for central authorities; their use makes smart contracts possible because blockchain networks collaborate to enforce rules across their entire ecosystem without middlemen intervening - creating the opportunity for smart contracts.
Conventional contracts are written agreements which outline the terms of an alliance and are legally binding. Should either party breach these conditions, party B may seek damages against Party A for breach. Smart contracts allow such rules to be automatically upheld without needing intervention by courts or third parties.
Ethereum was established in 2013 to facilitate the creation of smart contracts, making it currently one of the most-widely used platforms. Outside of Ethereum however, smart contracts aren't very common; some don't think they will become mainstream tools for managing transactions anytime soon; but supporters of Ethereum believe in its future potential; several applications already use smart contracts in various applications like MakerDAO and Compound that offer lending and interest-bearing to users.
Nick Szabo first conceptualized the notion of smart contracts in 1993 by likening it to digital vending machines. For his most well-known example of smart contract design involving food vending machines and beverages vending machines - including their users being able to enter $1 into one and obtain their preferred drink or snack from it - similar to how smart contracts should allow users to anticipate certain results (in this instance their desired drink), when giving certain input (such as $1). A basic example of an Ethereum smart contract involves sending 10 ether tokens but stipulates it cannot be distributed until after an explicit date has passed - similar to other smart contracts but in this instance with no set date on when distribution would happen.

Role Of Smart Contracts In Ethereum Blockchain
Basic smart contracts were first implemented by Bitcoin, the inaugural cryptocurrency in history; they remain more limited than Ethereum smart contracts today. Every transaction on Bitcoin counts as a smart contract since network approval of any given transaction depends on certain conditions being fulfilled such as providing proof that one owns cryptocurrency - this digital signature must come from the owner of a Bitcoin private key to validate.
Ethereum provides developers with more freedom in processing transactions beyond cryptocurrency transactions via blockchain technology, because of its "Turing-complete" language that supports a wider array of computational instructions than Bitcoin does and allows for any type of smart contract they could imagine being created on its blockchain - though novel smart contracts might not have been tested thoroughly enough, leading to millions lost due to vulnerabilities on ethereum's smart contract network.
Features Of Smart Contracts
The following are some essential characteristics of a smart contract:
Distributed: All terms of a smart contract are guaranteed to be accessible by all members on the network and cannot be altered by any single party. Each node linked to the network replicates and distributes one smart contract.
Deterministic: Smart contracts only operate properly under certain conditions and regardless of who executes them, their final result will always be identical.
Immutable: Once deployed, smart contracts cannot be reversed; removal will only be possible once all necessary functionality has been accomplished beforehand.
Autonomy: No other parties are involved; simply create the contract yourself, which will then be shared among all participants. Because no middlemen are present, bullying is reduced significantly while every party involved has complete authority. Furthermore, no single node on the network maintains or executes smart contracts which gives away all control power from them.
Customizable: Before being activated, smart contracts can be modified or customized to carry out specific actions for their user.
Transparent: Because smart agreements are hosted on blockchain technology - an open ledger where anyone can view its code - everyone who views or participates can see its contents.
Applications Of Smart Contracts
Here we have evaluated some of the application of smart contract in to life and industry of every person:
Real Estate: Reduce costs associated with intermediary involvement by sharing money among all real parties involved. One such smart contract enacting such an exchange may involve depositing predetermined sums of funds directly into the seller's wallet account (or equivalent).
Vehicle ownership: Blockchain can be utilized to implement smart contracts that keep track of car ownership and maintenance, for instance mandating that maintenance be conducted every six months; failure to adhere would result in license suspension.
Music Industry: Music industries could document ownership through blockchains to prove ownership. When songs are licensed commercially, royalties may be distributed back through smart contracts embedded into these blockchains to their owner - helping resolve ownership conflicts more quickly than before.
Government elections: There will be greater confidence against unethical practices because it would be extremely difficult to decrypt the voter address and change the vote once it has been recorded in the blockchain.
Management: Blockchain technology makes life decisions simpler by streamlining and automating them, streamlining each decision made later or later in life to be accessible by authority (for instance a smart contract can be used when producing 10 tonnes of plastic bags to kick start raw material supply.)
Healthcare: Fraud can be reduced through using smart contracts to automate healthcare payment procedures. Each treatment is tracked on an electronic ledger and the smart contract computes all transactions at the end. Before any bills have been settled and entered into their smart contracts, patients cannot leave hospital facilities.

Conclusion
Code known as smart contracts are added to blockchains as an efficient means to implement terms from third parties and perform contractual obligations more reliably than prior methods would allow. Smart contracts eliminate mutual trust requirements between the parties by automating tasks they would have otherwise needed to complete under their agreement.
Smart contracts are still in their infancy; users don't trust middlemen but must still trust that the code was written correctly - no easy feat with all the security flaws still present; over time numerous vulnerabilities have been revealed which allow malicious actors to raid user funds; hopefully as more developers contribute better code this problem should diminish over time.
