The evolution of trading platforms has been nothing short of remarkable. From the historical roots of trading in physical marketplaces, all the way to the digital revolution brought about by centralised exchanges, the same exact journey has now led us to possibly the forefront of innovation with decentralised exchanges (DEX).
This article will provide you a comprehensive exploration of the history of trading, the transition to centralised exchanges, and the emergence of decentralised exchanges. Additionally, we delve into the various types of decentralised exchanges and their impact on the future of trading.
So let’s get right into it!
A Journey Through Trading History
1. Early Marketplaces: The Origins of Trading
Trading has been a fundamental aspect of human civilization for centuries. The earliest forms of trading occurred in designated physical marketplaces where individuals gathered to exchange goods and services mostly through bartering systems.
- Emergence of Financial Instruments
Over time, these marketplaces evolved, and the need for a more sophisticated financial instruments arose. Promissory notes, Paper currency, and written contracts were then introduced.
- 3. The Birth of Stock Exchanges
The Amsterdam Stock Exchange, founded in 1602 by the Dutch East India Company, is often considered the world’s first official stock exchange. It introduced the issuance of shares to the public, allowing investors to buy and sell ownership stakes in the company. People would crowd around at a designated area that would be super crowded just to trade. The Amsterdam Exchange laid the foundation for the structured trading of financial instruments.
This led to a more structured formation of trading pits and open outcry. This method involved traders physically gathering in a designated area, often a large trading floor, to shout, use hand signals, and engage in face-to-face communication to execute trades. This marked the birth of the iconic trading pits.
In the mid-19th century, the Chicago Mercantile Exchange (CME) pioneered futures trading. Trading pits, especially in commodities like grains and livestock, became similar to the vibrant chaos of open outcry trading. Traders would use a combination of verbal and non-verbal communication to convey buy and sell orders.
4. The Rise of Centralised Exchanges
The advent of computers and electronic trading systems allowed for more efficient and automated matching of buy and sell orders. The digital age brought about a revolutionary shift in trading with the establishment of centralised exchanges. These platforms, exemplified by stock exchanges like the New York Stock Exchange (NYSE) and commodity exchanges, provided a centralised hub for buyers and sellers to execute trades globally. Centralised exchanges played a crucial role in facilitating liquidity, price discovery, and market efficiency.
The Era of Centralised Exchanges
1. Advantages of Centralization
Centralised exchanges offered benefits such as liquidity, price discovery, and a streamlined trading experience. Investors and traders could rely on these platforms to match orders, execute trades, and ensure a fair and transparent marketplace.
2. Challenges and Limitations
However, the centralised model came with its share of challenges. Trusting intermediaries with custody of funds led to instances of fraud, hacks, and manipulation. Additionally, centralised exchanges were subject to regulatory oversight, which, while providing a level of security, also restricted accessibility for certain users. Concerns regarding security vulnerabilities, potential for market manipulation, and the need to trust third-party intermediaries sparked a quest for alternative models.
Note:
- The idea behind it was that centralisation does not provide the full globalisation of financial markets as it is not as financially inclusive.
The Rise of Decentralised Exchanges(DEX)
1. Introduction to Decentralised Exchanges
Decentralised exchanges emerged as a response to the limitations of centralised platforms. It is built on blockchain technology as blockchain is a type of a distributed ledger technology that offers transparency, security and censorship resistance. DEX operates without a central authority, by utilising smart contracts on blockchains platforms like ethereum to automate and execute trades. This fundamental shift brings transparency, security, and greater control back to users.
- How Decentralised Exchanges Work
Decentralised exchanges operate on the principles of transparency and peer-to-peer interaction. Smart contracts, self-executing pieces of code, facilitate trades without the need for a central authority. Users retain control of their private keys, ensuring security and reducing the risk of unauthorised access.
a. Smart Contracts
Smart contracts are the cornerstone of decentralised exchanges. These self-executing contracts, coded on the blockchain, automate the trading process, eliminating the need for intermediaries. This automation enhances security and ensures trustless transactions.
b. Peer-to-Peer Trading
DEX facilitates peer-to-peer trading, allowing users to retain control of their private keys and funds. By eliminating the need for a centralised custodian, the risk of hacking and unauthorised access is significantly reduced.
c. Liquidity Pools and Automated Market Makers (AMM)
To ensure liquidity and facilitate trading, decentralised exchanges often leverage liquidity pools and AMMs. Users contribute funds to these pools and earn fees in return. AMMs use algorithms to adjust prices based on supply and demand, ensuring continuous and efficient trading.

3. Types of Decentralised Exchanges
a. On-Chain Order Book Exchanges
Centralised exchanges utilise order books to match buyers and sellers. The same is also being implemented in Decentralised exchanges (Dexes) in which they utilise an on-chain order book, where all trading activities are recorded on the blockchain. Users can place and execute orders directly through smart contracts.
b. Off-Chain Order Book Exchanges
In contrast to on-chain order book exchanges, there are Off-chain order books. These decentralised exchanges (Dexes) process trades off-chain, offering faster transaction speeds while still benefiting from the security of blockchain technology.
c Automated Market Makers (AMM)
AMMs, such as Uniswap and PancakeSwap, use liquidity pools and algorithms to automatically adjust prices based on supply and demand. A mathematical constant of k is used to calculate and balance the pool accordingly. Users can also provide liquidity to these pools and earn fees also known as liquidity mining.
d. Cross-Chain Decentralised Exchanges
As blockchain ecosystems expand, cross-chain decentralised exchanges like Thorchain enable the exchange of assets across different blockchain networks, promoting interoperability.
Note:
- Although there are different types of Decentralised exchanges (Dexes), the main type of dexes being utilised are Automated Market makers (AMM)
- Blockchains are not interoperable, hence cross chain protocols exist.

Advantages and Challenges of Decentralised Exchanges
1. Advantages
a. Security and Control
Decentralised exchanges prioritise user security by eliminating the need to trust a central authority with funds. Users maintain control of their private keys, reducing the risk of hacking and fraud.
Note:
- Decentralised exchanges (Dexes) does not have central authority, essentially the way in which the smart contract has been coded prioritises user security. There is no customer support or team behind Dexes
b. Global Accessibility
DEX operates on a global scale, allowing users worldwide to access and trade assets without the limitations imposed by geographical boundaries. This inclusivity opens up new opportunities for investors and traders.
Note:
- This allows anyone with an internet connection and a device to participate in a Dexes. Although there is some level of understanding required before trading. There is an article written about getting started with DeFi here.
c. Reduced Counterparty Risk
Traditional exchanges involve counterparty risk, where users rely on the exchange to execute trades. With decentralised exchanges, trades occur directly between users through smart contracts, minimising counterparty risk.
Note:
- since it is strictly peer to peer through liquidity pools, there is little to no counterparty risk. You just need to ensure there is liquidity within the pool for you to trade and other risks factor which is different of that of centralised exchanges
2. Challenges and Considerations
While decentralised exchanges offer numerous benefits, challenges and considerations exist. Issues such as liquidity constraints, potential front-running, and the learning curve associated with using decentralised platforms are important factors to be mindful of.
Learning curve for decentralised finance is not as straightforward but rather it may be complex. In an individual sense. It is important to be well-informed when dealing with the decentralised finance world!
Note: Centralisation and decentralisation in finance has its own Pros and cons. We dived deeper into each of them here
Conclusion
Decentralised exchanges represent a potential transformative force in the future of trading. Enabling users to trade without the need of an intermediary. In this current state of the world. Many institutions and companies have embedded themselves and slither between the knowledge gap of the uninformed and the markets. Earning substantial fees along the way which does not lead to optimised opportunities for end-users. Hence, Understanding Dexes, from the early marketplaces to centralised exchanges and now the decentralised frontier, is crucial in appreciating the significance of this evolution. As we navigate the future of trading armed with this knowledge, we are better equipped to embrace the possibilities and innovations that decentralised exchanges bring to the financial ecosystem.
Whether through on-chain order book exchanges, automated market makers, cross-chain platforms, or off-chain order book exchanges, the diverse types of decentralised exchanges underscore the adaptability and resilience of this groundbreaking technology.
Embrace the journey, explore the opportunities, and navigate the future of trading with a profound understanding of how decentralised exchanges work, and the transformative impact they hold on the financial landscape. The future of finance is decentralised, and you are at the forefront of this exciting paradigm shift. Thank you for being here.
