As we move forward into a new era of financial innovation, smart contracts are reshaping the landscape by breaking down barriers and opening up vast opportunities for disrupting traditional finance. No longer confined to heavily regulated territories, the free flow of capital and money is becoming a reality. In this article, we’ll explore the concept of smart contracts, their origins, and how they’re set to revolutionize the way we transact and interact in the digital world. So, buckle up and get ready for a thrilling ride into the future of finance with Onooks Crypto Currency!

Smart Contracts: A Brief Overview
At its core, a smart contract is a computer program or transaction protocol designed to automatically execute, control, or document legally relevant events and actions based on the terms of a contract or agreement. The primary goals of smart contracts are to reduce the need for intermediaries, arbitration, and enforcement costs, as well as minimize fraud losses and both malicious and accidental exceptions.
Did you know that vending machines are often cited as the oldest form of smart contract technology? In 2014, the white paper for the cryptocurrency Ethereum described the Bitcoin protocol as a weak version of the smart contract concept, as defined by computer scientist, lawyer, and cryptographer Nick Szabo. Since Ethereum’s inception, various cryptocurrencies have supported scripting languages that enable more advanced smart contracts between untrusted parties.
It’s important to note that smart contracts should be distinguished from smart legal contracts. The latter refers to a traditional, legally-binding agreement in natural language with certain terms expressed and implemented in machine-readable code.
Breaking Free From Centralized Trust
Centralized trust is not only costly but also difficult to scale. The ultimate source of its power often lies in government or sovereign authority that dictates essential aspects of money within its realm, such as purchasing power, interest rates, and fiscal policies. Traditional money relies on a web of trusted parties, which act as bottlenecks for the flow of capital and money.
Since the creation of Bitcoin, the greatest achievement of blockchain technology is the ability to transact value across the network with a trust-minimized setup. This breakthrough removes the bottleneck for capital flow and restores money to its roots, allowing it to flow freely at the speed of light without friction.
Reimagining Assets and Reinventing Finance
The permissionless, trustless nature of cryptocurrency and blockchain technology enables us to reimagine assets and reinvent finance. Ethereum expands on Bitcoin’s capabilities as a value and settlement network, giving birth to a continuously evolving financial protocol network. Ethereum has fostered a fertile environment for financial and monetary experimentation on a global scale, empowering the open finance movement.
Ethereum: Beyond Currency
Ethereum was originally conceived as an upgraded version of a cryptocurrency, offering advanced features such as on-blockchain escrow, withdrawal limits, financial contracts, gambling markets, and more through a highly generalized programming language. While Ethereum doesn’t directly “support” these applications, its Turing-complete programming language allows for the creation of arbitrary contracts for any transaction type or application.
Decentralized file storage, computation, and prediction markets are just a few examples of protocols and applications that can greatly increase the efficiency of the computational industry. By introducing an economic layer, Ethereum can provide a significant boost to other peer-to-peer protocols.
ERC-20: The Standard for Fungible Tokens on Ethereum
One of the most important smart contract standards on Ethereum is ERC-20, which has emerged as the technical standard for all smart contracts on the Ethereum blockchain implementing fungible tokens. The ERC-20 standard defines a common set of rules that all fungible Ethereum tokens must follow. This enables developers to accurately predict how new tokens will function within the larger Ethereum ecosystem, simplifying their tasks and ensuring that each project won’t require a complete overhaul each time a new token is released, as long as the token adheres to the rules.
ERC-20 Functions and Implementation
Here’s an example of the ERC-20 interface, showcasing the functions an ERC-20 token must implement:
pragma solidity ^0.6.0;
interface IERC20 {
function totalSupply() external view returns (uint256);
function balanceOf(address account) external view returns (uint256);
function allowance(address owner, address spender) external view returns (uint256);
function transfer(address recipient, uint256 amount) external returns (bool);
function approve(address spender, uint256 amount) external returns (bool);
function transferFrom(address sender, address recipient, uint256 amount) external returns (bool);
event Transfer(address indexed from, address indexed to, uint256 value);
event Approval(address indexed owner, address indexed spender, uint256 value);
}
Understanding Token Balances
According to Solidity documentation, token units are represented as a multiple of a base unit called wei. For example, one Onooks (OOKS) token equals 10**18, or 1,000,000,000,000,000,000 wei.
Imagine a token contract with two token holders:
- 0x1111111111111111111111111111111111111111 with a balance of 100 units
- 0x2222222222222222222222222222222222222222 with a balance of 200 units
When holder 0x1111111111111111111111111111111111111111 transfers 10 tokens to 0x2222222222222222222222222222222222222222, their respective balances update accordingly:
- 0x1111111111111111111111111111111111111111 has a new balance of 90 units
- 0x2222222222222222222222222222222222222222 has a new balance of 210 units
Smart Contract Use Cases
Smart contracts are best suited for industries where automatic execution processes are beneficial, such as healthcare, banking, real estate, and insurance. By adopting blockchain-based smart contract technology, these industries can greatly streamline their processes using algorithms, rules, and intelligent coding.
