What Are Tokens And Smart Contracts?
Smart contracts are coded agreements stored in blockchain-based ledgers. The alignment of certain pre-set conditions allows the execution of smart contracts which are then made accessible instantaneously to all parties involved, keeping them updated without intervention from outside agents. Smart contracts have assisted in activities related to fund transfer, insurance, and legal agreements. They have acquired attention and popularity owing to their rapid, secure, transparent, efficient, and economic nature.
Pertaining to blockchain, tokens can be considered as an agency using which a smart contract can be executed. Tokens are digital assets, or electronic files with some value attached to them. They can be used for making payments and signing digital contracts.
How Smart Contracts Work
Smart contracts function through simple coded logic and run on ledgers in a distributed form, based on blockchain technology.
- In order to create a structure for a smart contract, businesses assign developers and fix the conditions under which the transactions are to be executed.
- Businesses may also choose from different tools and platforms for creating blockchain smart contracts, available online.
- The employed developers then translate the conditions into code, which needs to be tested before deployment.
- Once the code is generated, it is installed in a blockchain system and distributed among the parties involved.
- The contract in codified form is then verified by the concerned parties and upon fulfillment of the contract conditions, executed, keeping involved parties in the loop.
Benefits And Uses Of Smart Contracts
Owing primarily to the way they are structured, smart contracts have a range of benefits to offer
1. Efficiency in terms of time and resources
Smart contracts execute transactions instantaneously. The fact that only concerned parties are involved indicates towards an automated system and reduced organizational costs.
2. Trustless nature of smart contracts
External parties are not involved, and transaction information cannot be altered in a shared and encrypted system.
Altering any information on the blockchain based distributed ledger.would entail hacking and altering the entire chain.
Smart contracts, owing to their precise and secure nature, can be used for fund transfers, data collection, protecting documents from forgery, making supply chains more efficient, crowdfunding, identity management, finance, Banking and Insurance, property ownership, registering users and so on.
Real-World Applications Of Smart Contracts
A look at some real-world smart contract related scenarios will help to put this discussion into perspective
1. Aiding international trade
Blockchain-based smart contracts ensure a regulated, simple, and frictionless trading and exchange experience for senders and receivers, ensuring also that the transaction fees associated is only limited to the blockchain being used.
2. Efficient supply chains
Increased accessibility and reduced wastage of, for instance, food or medical supplies, due to better visibility are key factors associated with smart contracts in supply chains. Miscommunications between suppliers and recipients are resolved in a quick and efficient manner, owing to the flexibility that smart contracts offer.
3. Ownership of property made easier
Smart contracts assist in processing paperless transactions and offer a broadened scope when it comes to buying and selling of property. Lengthy processes can be eliminated in the process of record keeping through smart contracts online.
4. Transparent voting methods
An ideal method of checking and putting an end to fraudulent voting practices could be through smart contracts, where each voter is assigned only one vote and their identity and voting record is verified using blockchain based smart contracts.
- Identity management
The decentralized system that smart contracts are based on protects against identity theft by ensuring that participants possess the power to control how data related to them is stored and shared.
Overcoming Challenges Of Smart Contracts
Scalability is an issue when it comes to smart contracts. For instance, Ethereum can currently process upto 30 transactions per second. With Ethereum 2.0, this number is supposed to change into 100,000 per second.
● Legal know-how required
Since smart contracts reduce or eliminate dependency on legal intermediaries, it is essential to know certain aspects related to different types of law well.
● Anomalies may crop up
As a technology that is new in the market, smart contracts are susceptible to internal errors or anomalies that may provide hackers easy access to tamper with the information stored.
The Future Of Smart Contracts
The concept of blockchain related decentralized processes has enabled disintermediation, with low dependency on banks and legal institutions. The increasing popularity that smart contracts continue to enjoy indicates that the adoption of blockchain based smart contracts will continue to grow, offering more power into the hands of participants.
