Crowdsourcing 2.0: Blockchain will restore trust in information

Prediction markets are one of the most compelling applications of blockchain technology today, with betting volume exceeding $3.1 billion in the third quarter of this year, and that is no coincidence. Polymarket – the leading prediction market platform widely regarded as crypto’s first “killer app” – has done what few other blockchain applications have done: capture mainstream attention and influence major events, accounting for 99% of the prediction market share. Take the 2024 US elections for example. Polymarket reached US households through mainstream media, going beyond crypto-native circles and showing how blockchain can fundamentally change the way we interact with knowledge.

But the point is: prediction markets are just one part of a much more important shift: an evolution in information generation and verification. And it’s not just a small improvement; it’s a transformation that takes the proven success of crowdsourced platforms like Wikipedia and Reddit to the next level.

The rise and fall of crowdsourcing platforms

Wikipedia and Reddit were groundbreaking; they were innovative in the early 2000s, revolutionizing how collective wisdom can be harnessed. Wikipedia’s open editing model created a global hub for knowledge, using diverse information contributions to build a widely trusted source. Reddit sparked a public debate in which positive and negative voices represented the community’s consensus on what content was valuable and trustworthy. These platforms democratized access to information and opinions in a way that centralized media never could.

But their shortcomings cannot be overlooked. As successful as they were, these platforms fell short in crucial ways. For all its strengths, Wikipedia has struggled to maintain neutrality; content wars and biased edits are inevitable in an open editing system in which a relatively small group of editors ultimately approve changes, allowing the community to rely on their objectivity. Despite the promise of democratized opinions, Reddit often unintentionally promotes clickbait or sensationalism, favoring content that attracts votes over accuracy. While these two platforms are just examples of the many crowdsourcing platforms, they remain vulnerable to manipulation – whether through misinformation, organized brigades, or groupthink – even as they continue to be widely used.

That’s where blockchain comes into the picture, and this evolution is not optional, but essential.

Blockchain is the next step in crowdsourcing

Blockchain addresses the issues that have long plagued crowdsource platforms: trust, accuracy and sustainability. These platforms are built on collective wisdom, but without the right protocols there is always a crack through which misinformation and open-mindedness can slip through. This is not much different from the current problems we see in traditional media, where even the best intentions can fail if the systems that support them are flawed. What blockchain provides is the missing piece: transparency, accountability, and a system of incentives for truth over popularity.

Every edit, vote or contribution is immutably recorded, making manipulation of the system in the shadows impossible. The transparency that blockchain-enabled proof-of-unique human protocols provide could fundamentally change the dynamics of accountability and trust in ways that open editing systems have always struggled to do. These protocols make it impossible to set up many accounts to manipulate outcomes, creating a level of radical transparency that fundamentally shifts the dynamics of trust and ensures that users can trust the integrity of information because it has not been tampered with .

As we’ve seen at Polymarket, prediction markets solve what Reddit’s voting system can’t: reward truth, not popularity. In the case of Reddit, the upvote system has allowed the community to surface content that is particularly popular. That said, popularity does not equal truth. It is relatively easy to game the system; Clickbait headlines often rise to the top if they are misleading or inaccurate. Prediction markets force participants to bet on what is true. If you do well, you will be rewarded; if you do it wrong, you lose. Accuracy, not attention, becomes the deciding factor in this market-driven approach, creating a self-regulating system that prioritizes verifiable truth.

Blockchain also offers a solution to journalism’s broken financial model. Traditional crowdsourced platforms struggle to create sustainable financial models that do not compromise quality. Blockchain introduces decentralized financing models, such as quadratic financing, where it is the community and not advertisers or corporate interests that decide what content should receive funding. A self-sustaining system is being created where high-quality journalism can thrive, free from the pressures of paywalls or ad-driven content. Information is not just a product; it is a public good and must remain accessible and free – something that blockchain can ensure.

In addition to just information, blockchain also decentralizes opinion. Rather than leaving the public debate to the corporate media and a few influential voices, prediction markets let the public decide which journalism or research is important. People don’t just consume news; they stake their reputation and money on what they believe is right. Over time, the masses validate what is true, creating a decentralized system that makes it much harder for bad actors to manipulate public opinion.

Most importantly, blockchain brings accountability, something that is sorely lacking in traditional crowdsourcing platforms. Crowdsourcing platforms allow users to contribute anonymously or without real consequences. This creates room for trolls, bots or bad actors to disrupt the system. Blockchain solves this by ensuring that every decision one makes is fully auditable. There is a clear chain of responsibility and users are held accountable for their actions. You no longer have to hide behind anonymity: blockchain ensures that contributors must adhere to the integrity of the information they support.

The future of crowdsourcing and blockchain

Here’s the truth: crowdsourced platforms, as we know them, are already outdated. Wikipedia and Reddit were revolutionary for their time, but they simply cannot solve the problems of trust, bias, and financial sustainability we face today. Blockchain is not just the next step, it is the necessary evolution.

In the future, crowdsourced platforms will not just be places where information is collected; they will be active marketplaces where quality, truth and value are determined by users, not centralized gatekeepers. Blockchain, prediction markets and decentralized financing models such as quadratic financing are already building that future. These tools are not optional add-ons; they form the foundation of a decentralized, transparent internet where unbiased journalism and high-quality research thrive.

So the question is no longer as blockchain will bring the next evolution – it’s when.
