What Is the Predefined Business Logic Within a Blockchain Called?

What Is the Predefined Business Logic Within a Blockchain CalledBlockchain has revolutionized the way information is stored and shared. Blockchain systems are transparent and are maintained by a global network of computers not controlled by any single entity.

This article looks into how the predefined business logic in a blockchain that controls transactions within the blockchain network work, their benefits and applications.


The Predefined Business Logic Within a Blockchain

The predefined business logic in blockchain is a set of processes, protocols, and rules that are encoded and arranged in advance inside a blockchain network. The consistency, dependability, and immutability of the data and procedures are ensured by the logic that controls transactions and interactions within the blockchain.

It encompasses the predetermined algorithms, conditions, and decision-making frameworks that govern how transactions are executed and verified. The predefined business logic within a blockchain are called smart contracts.

From automating complex processes to building trustless systems, this technology holds immense potential to transform various industries.


What Are Smart Contracts?

Smart contracts are programmable pieces of code that reside on a blockchain. They are encoded with predefined rules and conditions, allowing them to execute automatically when triggered by specific events or criteria.

The decentralized nature of blockchain ensures that the terms of the contract are executed without the need for a centralized authority. By automating the terms of an agreement, it eliminates the need for intermediaries and ensures transparency through immutability, thus reducing the risk of fraud and manipulation.

Smart contracts are emerging as potent and revolutionary components in the field of blockchain technology, changing the way traditional agreements and transactions are conducted. Operating on blockchain systems like Ethereum, these self-executing contracts redefine how parties interact in contractual agreements by bringing automation, transparency, and efficiency to new heights.


How Do Smart Contracts Work?

Smart contracts consist of three main components: the code, the data, and the state.

  • The code encapsulates the logic and conditions of the contract, defining how it should behave under different circumstances.
  • The data represents the information the contract operates on.
  • The state reflects the current condition or stage of the contract’s execution.


Together, these components create a dynamic and self-contained system that can interact with the blockchain and other smart contracts seamlessly.  

Smart contracts function on the principle of ‘if/then’ statements written in code. These statements define the terms of an agreement, specifying what needs to happen under specific conditions. 

  • Parties involved agree on the terms and conditions of the contract, which are then translated into code by developers. 
  • The coded contract is then submitted to the blockchain network. 
  • Miners or validators verify the code and add it to a new block on the blockchain, making it immutable and publicly accessible.
  • The smart contract continuously monitors the blockchain for the predefined conditions to be met. This could involve verifying payments, receiving data, or checking external sources. 
  • Once the conditions are met, the code automatically triggers the corresponding actions. This could involve transferring funds, releasing documents, or updating ownership records. 
  • Every step of the process is recorded on the blockchain, providing complete transparency and auditability for all parties involved.


Benefits of Smart Contracts

Below are some benefits associated with the use of smart contracts.

1. Automation of Processes

One of the primary advantages of smart contracts lies in their ability to automate processes. This automation streamlines the entire process, reducing the need for intermediaries and ensuring swift and accurate transactional outcomes.

For instance, in a real estate transaction governed by a smart contract, the transfer of ownership and funds could be automatically triggered once all conditions, such as successful inspections and payment, are met. This level of automation not only accelerates the pace of transactions but also minimizes the scope for human error.


2. Enhanced Transparency

As smart contracts operate on a blockchain, the decentralized and distributed ledger records every transaction in a transparent and immutable manner. This ensures that all parties involved can view the contract’s terms and conditions.

Unlike traditional agreements where information might be hidden or subject to interpretation, smart contracts show the entire transaction history.

Each participant in the network maintains a copy of the blockchain, and the data is kept secure and accurate with consensus protocols. This transparency builds trust among parties, as they can independently verify the execution and history of the smart contract.


3. Reduction of Intermediary Costs

Smart contracts significantly reduce the reliance on intermediaries, such as banks, brokers, or legal representatives, in the execution of agreements. The removal of these intermediaries leads to a reduction in associated costs and fees.


4. Trustless Transactions

Smart contracts introduce the concept of trustless transactions, wherein participants don’t need to have prior relationships to validate the authenticity of the other party. The rules encoded in the smart contract are executed automatically, providing a level playing field for all participants and reducing the potential for disputes.


5. Immutability and Auditability

A smart contract’s code and execution history become immutable once it is implemented on the blockchain. Immutability ensures that the terms and conditions encoded in the contract remain unchanged over time and allows for a comprehensive review of the entire transaction history at a later date.


6. Global Accessibility

Smart contracts operate on blockchain networks that are accessible globally, which opens up new possibilities for businesses and individuals to transact without geographical or time zone restrictions.


7. Conditional Execution and Escrow Services

Smart contracts excel in conditional execution, that allow creating agreements when conditions are satisfied. Escrow services, where a third party holds funds until certain conditions are met, can be seamlessly implemented using smart contracts.

For instance, in a crowdfunding campaign, funds raised could be held in escrow, and the smart contract would release the funds to the project once predefined milestones are achieved. This conditional execution not only adds a layer of security but also ensures that the terms of the agreement are met before the transaction is finalized.


8. Programmable Money and Tokenization

Smart contracts enable the creation of programmable money, allowing developers to define conditions under which funds are transferred. This programmability extends to the tokenization of assets, where physical or digital assets are represented as tokens on the blockchain.

Real estate, art, or even shares of a company can be tokenized, making them divisible, tradable, and easily transferable through smart contracts.

The programmable nature of smart contracts provides a flexible framework for creating innovative financial instruments and decentralized applications (DApps). It opens up possibilities for creating new economic models and democratizing access to financial services.


9. Dispute Resolution and Trust Mechanisms

The transparent and immutable nature of the blockchain provides a clear record of the contract’s execution, making it easier to resolve disputes based on objective evidence. Additionally, certain blockchain platforms and smart contract protocols include mechanisms for trustless dispute resolution.

Decentralized Autonomous Organizations (DAOs) and decentralized governance structures allow token holders to vote on proposed changes or resolutions, creating a democratic and decentralized decision-making process.


Challenges in Implementing Smart Contracts

While the implementation of business logic on the blockchain offers unprecedented opportunities for transparency, efficiency, and trust, it comes with its own set of challenges. Addressing these challenges is crucial for realizing the full potential of smart contracts.

1. Security Concerns

Smart contracts are susceptible to security vulnerabilities. Bugs or loopholes in the code can be exploited, leading to financial losses or disruptions in the execution of contracts. Rigorous testing, code audits, and the use of formal verification tools are essential in identifying and addressing security vulnerabilities.


2. User Experience and Adoption

The complexity of interacting with blockchain-based applications and smart contracts can be a barrier to user adoption. Users may find the process confusing, thus limiting the widespread use of decentralized applications. User-friendly interfaces, better educational resources, and enhanced onboarding processes are essential in improving the user experience.


3. Upgradability and Governance

Once a smart contract is deployed on the blockchain, making changes to its code can be challenging. The lack of upgradability can hinder the adaptability of decentralized applications to evolving requirements.

Implementing mechanisms for upgradability, such as proxy contracts or modular architectures, allows for the modification of smart contracts without disrupting their functionality. Governance models that involve token holders in decision-making processes can also address issues related to protocol upgrades and modifications.


4. Gas Griefing 

Gas griefing refers to a malicious practice within blockchain ecosystems, particularly on platforms utilizing gas fees, such as Ethereum. In this context, “gas” refers to the computational cost required to execute operations on the blockchain.

Gas griefing occurs when a user exploits the transparent nature of transactions and intentionally raises gas fees to disrupt the network or target specific users.


5. Attacks

Few of the most frequent and harmful cyberattacks that are used against smart contracts include:

  • Force-Feeding Attacks

These involve malicious actors exploiting vulnerabilities in smart contracts to manipulate their execution by consuming excessive computational resources. This intentional congestion can disrupt blockchain networks, leading to increased transaction fees and delays.

  • Reentrancy Attacks

These attacks allow the hacker to withdraw resources repeatedly without waiting for verification. This can lead to unauthorized access to funds or manipulation of contract states.

  • Frontrunning

Frontrunning in blockchain occurs when a malicious actor exploits the advance knowledge of pending transactions to manipulate the market. By executing trades ahead of others, the frontrunner gains an unfair advantage, potentially leading to price manipulation.

  • Denial of Service (DoS) Attacks

DoS aims to disrupt the normal functioning of the system by overwhelming it with excessive traffic or requests. In blockchain, a DoS attack can congest the network, causing delays and hindering transactions.
