Why Index.fun is building with TRUF.NETWORK
Why builders are rethinking resolution systems.
Day 54 of 100 Days of TRUF
When a $237M prediction market can be steered off course by a handful of whales, it’s a wake-up call for anyone building in Web3.
That’s the conversation Index.fun sparked this week with their take on the now-infamous Zelenskyy suit prediction on Polymarket.
The question was simple:
Would Ukrainian President Volodymyr Zelenskyy wear a suit during his next public appearance?
The evidence was overwhelming - photos, video clips, and international press coverage all confirmed he did. Yet, when it came time to settle, the market resolved NO.
Not because reality was ambiguous. But because a small number of large token holders voted against the facts.
In Index.fun’s words:
“Prediction markets should reflect real-world outcomes, not the opinions or incentives of a few powerful token holders… This isn’t decentralization. It’s control.”
What happened with the Zelenskyy suit market points to a deeper issue; resolution systems vulnerable to whale influence and private coordination.
For builders like Index.fun, that’s not good enough.
Building on verifiable data, not votes
That’s why Index.fun chose to build with TRUF.NETWORK. We provide a trustworthy backbone: replicated databases, standardized queries, and multi-attested messages from independent validators. Honest nodes are incentivized by design, while bad actors are penalized, a model that draws on Satoshi’s original vision of aligned incentives.
No voting. No committees. No insiders deciding what “really” happened. Just transparent, auditable data powering market outcomes.
This matters because prediction markets only work if participants trust that results reflect the truth, not the preferences of the biggest wallets. With TRUF.NETWORK, Index.fun can focus on building innovative markets without worrying about resolution games.
As the Index.fun team put it:
“Markets should be decided by facts, not by who holds the most voting power.”
We couldn’t agree more.
Why this matters for Web3
Prediction markets are one of Web3’s most powerful primitives, turning collective foresight into tradable assets. But when resolution systems fail, the entire premise collapses.
That’s why TRUF.NETWORK exists: to provide a “Source of Truth” for markets, indexes, and financial products. Apps like Index.fun, Nuon.fi, and Truflation already use TRUF to ensure outcomes are grounded in reality, not narratives or influence. As Vitalik ButerinVitalik Buterin has highlighted how AI could accelerate information-based finance, provided the underlying data is verifiable and tamper-proof.
We’re proud to see Index.fun leading the charge for fairer, fact-based markets.
