Introduction
When you see the terms “blockchain” and “marketplace” in the same sentence, you undoubtedly think of the ecosystem of trading platforms that facilitate the thriving cryptocurrency trading.
However, blockchain technology has a wide range of uses, enabling the creation of various types of markets beyond cryptocurrencies. This article explores how blockchain technology can revolutionize one particular type of market: prediction markets.
What are prediction markets?
Prediction markets are speculative platforms where participants trade based on the outcomes of future events rather than traditional financial assets. Participants buy and sell contracts and receive payouts based on the outcome of a specific event.
For example, consider a prediction market question: “Will a train service from the United States to Europe be operational by 2035?” Traders can buy contracts betting on “yes” or “no.” If the train service is operational by the deadline, the “yes” contract will be worth $1, while the “no” contract will be worth nothing, and vice versa.
The value of these contracts can fluctuate as market sentiment and information change. For example, if advances are made in underwater tunneling technology, the price of a “yes” contract could rise.
Conversely, if no such development occurs, the value of a “no” contract may rise. Prediction markets are powerful forecasting tools because they bring together diverse information and insights from many participants and often produce forecasts with extremely high accuracy.
Prediction markets can cover a wide variety of topics. These include political elections, economic indicators, sporting events, and even weather forecasts. Essentially, any event with an uncertain outcome can be the subject of a prediction market. This versatility allows prediction markets to tap into the collective wisdom of a wide range of fields, providing valuable insights that may not be discovered through traditional analysis.
Why do prediction markets work?
Prediction markets work because participants are financially incentivized to act on their knowledge and insights. Unlike traditional gambling, which relies largely on luck, prediction markets rely on participants’ knowledge of external factors that influence outcomes.
In our train example, if the “no” contract is trading at $0.90 and the “yes” contract is trading at $0.10, it means that the market collectively believes there is a high probability that the train will not be operational before 2035.
These markets excel at collecting and presenting collective wisdom, operating on the principle that the combined knowledge of a group is often more accurate than that of an individual expert.
By analyzing prediction market data, stakeholders across industries can gain valuable insights into future trends and possibilities. Some proponents even argue that prediction markets lay the foundation for a new form of democracy called futarchy, in which policies are made based on their predicted impact on overall well-being.
Prediction markets act as information aggregators. Participants with inside information or expertise are financially incentivized to report their insights through trading. The resulting market price reflects the collective view on the likelihood of an event.
This capability makes prediction markets extremely useful in forecasting and decision making. Businesses can use these insights to develop strategies, governments can gauge public attitudes towards policies, and investors can identify emerging trends.
Prediction Market and Blockchain Technology
Decentralizing prediction markets through blockchain technology can significantly enhance the value proposition of prediction markets. Traditional centralized platforms have limitations because they require users to trust the platform operator.
Blockchain-based prediction markets have many advantages:
Censorship resistance
Centralized prediction markets can easily go out of business or be restricted. Decentralized platforms governed by smart contracts eliminate single points of failure. Every node on the network runs the same code, making it nearly impossible for any entity to compromise the platform.
Blockchain technology ensures that once a prediction market is deployed, it can operate independently and is not controlled by any single entity. This decentralization means that no single organization can easily censor or manipulate the market.
For example, in politically sensitive areas, traditional prediction markets may be shut down to prevent the spread of certain information. However, decentralized prediction markets running on blockchains can resist such censorship and become a more reliable and open platform for information exchange.
Eliminating the middlemen
Blockchain technology enables users to interact directly with smart contracts, eliminating the need for intermediaries. This reduces the costs and counterparty risks associated with centralized platforms because users do not have to trust third parties or pay additional fees.
Smart contracts can automatically execute market transactions, ensuring that agreements are fulfilled exactly as specified. This automated process reduces the possibility of human error and fraud.
For example, in traditional prediction markets, participants must trust the platform operator to accurately decide bets and allocate payouts. In blockchain-based markets, smart contracts automatically handle these tasks, improving the transparency and trustworthiness of the system.
Improve accessibility
Decentralized prediction markets are permissionless markets that can be participated by individuals from all over the world. This provides opportunities for a wide variety of participants, making the composition of participants diverse and inclusive.
In traditional prediction markets, participants may face various barriers, such as high fees or geographical restrictions. However, blockchain-based markets are open to anyone with an internet connection.
This inclusivity not only democratizes access to the market, it also brings more comprehensive insights and perspectives to the market. For example, a user in a remote area with local knowledge can participate in a prediction market on a global platform, providing unique insights that might otherwise be overlooked.
Functions of blockchain oracles
One of the challenges facing decentralized prediction markets is determining the outcome of an event without a central authority. Blockchain oracles address this problem by providing a mechanism to verify real-world outcomes. There are a variety of ways to run an oracle:
Third-party feeds: Simple but undermines decentralization as a third party controls the resulting data.
Incentivized reporting: Users will receive financial rewards for reporting truthfully. For example, some prediction markets use a staking mechanism, where users stake tokens and report results. Reporting truthfully will be rewarded, while fraudulent reporting will result in the loss of staked tokens.
Blockchain oracles are essential to ensure the accuracy and trustlessness of prediction market results. Oracles act as a bridge between blockchain and the real world, providing reliable data feeds. In the weather prediction market, oracles can extract data from multiple trusted sources of meteorological information to verify the results.
There are a variety of oracle solutions being developed to improve the reliability and security of prediction markets. Some use a decentralized network of reporters who verify data through consensus mechanisms. Others use a combination of decentralized verification and trusted data feeds. As blockchain technology develops, these oracles will become more sophisticated, providing better assurance of accuracy and tamper-proof results.
Future prospects and challenges
While blockchain-based prediction markets hold great potential, they also face challenges. Scalability remains a significant issue as current blockchain networks struggle to cope with high transaction volumes.
Scalable blockchain solutions such as rollups and other layer-2 technologies may help alleviate these bottlenecks encountered and enable prediction markets to operate more efficiently.
Regulatory uncertainty also poses a challenge. As prediction markets become more popular, regulators may impose greater scrutiny on the market over issues such as gambling laws and market manipulation. Clear and supportive regulatory mechanisms can help ensure that these markets develop in a direction that maximizes benefits while mitigating potential risks.
Another potential growth area is the integration of prediction markets with other blockchain applications. For example, decentralized finance (DeFi) platforms can introduce prediction markets to provide innovative financial products. Imagine a DeFi protocol where users can hedge their risks by participating in economic indicator prediction markets. Such integrations can create new opportunities and promote the application of prediction markets in the broader blockchain ecosystem.
Conclusion
Prediction markets are not only a great tool for betting on future outcomes, but also an advanced means of gathering reliable information in a variety of fields. By using economic incentives to get individuals to share their information, prediction markets can provide insights into social, industry, and political trends.
Decentralized alternatives powered by blockchain technology are addressing the limitations of centralized platforms. As more advanced oracles become available, the reliability and transparency of these platforms will increase, unlocking the true potential of prediction markets.
The integration of prediction markets and blockchain technology is expected to create a mechanism that can more effectively utilize collective wisdom, where access to the market is more convenient and fair, and information flows more freely and securely.
