Crowdsourcing 2.0: Blockchain will restore trust in information | Opinion

Prediction markets are one of the most compelling applications of blockchain technology today, with over $3.1 billion in betting volume over Q3 this year, and it’s no accident. Polymarket—the leading prediction market platform widely regarded as crypto’s first ‘killer app’—has done what few other blockchain applications have: captured mainstream attention and influenced major events, accounting for 99% of prediction market share. Take the 2024 US elections, for instance. Polymarket reached American households through mainstream media, moving beyond crypto-native circles and showing how blockchain can fundamentally change how we interact with knowledge.

But here’s the thing: prediction markets are just one part of a much more significant shift—an evolution in generating and verifying information. 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—innovating throughout the early years of the 2000s, they revolutionized the way collective wisdom can be harnessed. Wikipedia’s open-editing model created a global hub for knowledge, leveraging diverse information contributions to build a widely trusted resource. Reddit gave rise to a public discourse where upvotes and downvotes represented the community’s consensus on what content was valuable and reliable. These platforms democratized access to information and opinions in a way that centralized media never could.

But their flaws cannot be overlooked. As successful as they were, these platforms fell short in critical ways. For all its strengths, Wikipedia has struggled to maintain neutrality—content wars and biased edits are inevitable in an open-editing system where a relatively small group of editors ultimately sign off on changes, leaving the community to trust their objectivity. Despite its promise of democratized opinions, Reddit often unintentionally promotes clickbait or sensationalism, favoring content that attracts votes rather than accuracy. While these two platforms are just examples among 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 steps in, and this evolution isn’t optional—it’s essential.

Blockchain is the next leap in crowdsourcing

Blockchain addresses the very issues that have long plagued crowdsource platforms—trust, accuracy, and sustainability. These platforms were built on the premise of collective wisdom, but without the correct protocols in place, there is always a crack through which misinformation and unbiasedness can slip. This is not dissimilar to the current problems seen across legacy media, where even the best intentions can fall to the wayside if the systems supporting them are flawed. What blockchain offers is the missing piece: transparency, accountability, and a system of incentives for truth over popularity. 

Every edit, vote, or contribution is recorded immutably, making manipulating the system in the shadows impossible. The transparency blockchain-enabled proof-of-unique human protocols offer can fundamentally change the dynamics of accountability and trust in a way that open-editing systems have always struggled with. These protocols make it impossible to set up many accounts to manipulate outcomes, bringing a level of radical transparency that fundamentally shifts the dynamics of trust into making sure users can depend on the integrity of information because it hasn’t been tampered with.

As we’ve seen with Polymarket, prediction markets provide a solution for what Reddit’s voting system cannot: 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 doesn’t equate to truth. It’s relatively easy to game the system; clickbait headlines often rise to the top if misleading or inaccurate. Prediction markets force participants to bet on what is true. Get it right, and you’re rewarded; get it wrong, and 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 the broken financial model of journalism. Traditional crowdsourced platforms have struggled to create sustainable financial models that don’t compromise quality. Blockchain introduces decentralized funding models, like quadratic funding, whereby it is the community and not advertisers or corporate interests that decide on which content should receive funding. A self-sustaining system is achieved wherein high-quality journalism can thrive, free from the pressures of paywalls or ad-driven content. Information isn’t just a product; it’s a public good and should remain accessible and free—something blockchain can help ensure.

Beyond just information, blockchain is decentralising opinion too. Instead of leaving public discourse in the hands of corporate media and a few influential voices, prediction markets allow the crowd to determine which journalism or research holds weight. People don’t just consume news—they stake their reputation and money on what they believe is accurate. Over time, the crowd validates what’s true, creating a decentralized system that makes it much harder for bad actors to manipulate public opinion.

Most importantly, blockchain brings accountability, something sorely lacking in traditional crowdsourcing platforms. On crowdsourcing platforms, users can contribute anonymously or without real consequences. This creates room for trolls, bots, or bad actors to distort the system. Blockchain fixes this by ensuring that every decision one makes is fully auditable. There’s a clear chain of responsibility, and users are held accountable for their actions. No more hiding behind anonymity—blockchain ensures that contributors have to stand by 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 can’t solve the problems of trust, bias, and financial sustainability that we face today. Blockchain isn’t just the next step—it’s the necessary evolution.

In the future, crowdsourced platforms won’t just be places to gather information; they’ll be active marketplaces where quality, truth, and value are decided by users, not centralized gatekeepers. Blockchain, prediction markets, and decentralized funding models like quadratic funding are already building that future. These tools aren’t optional add-ons; they’re the foundation of a decentralized, transparent internet where unbiased, high-quality journalism and research thrive.

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