✍️ What Polymarket got Right that the Experts Got Wrong 👉Read(EN)
Polymarket demonstrated the unique accuracy of prediction markets over traditional media in forecasting and calling the election. By midnight on election night, Polymarket’s decentralized traders had already priced Trump’s odds of winning at 97%, long before any media outlet had even called a single swing state. This divergence reflects a deeper issue: while media and polling suffer from sampling biases and the pressures of public narrative, Polymarket’s structure relies on financial stakes and decentralized input, unconstrained by ideology.
✍️ EOF is up to 3x more efficient in zkVMs 👉Read(EN)
A very interesting result from the Succinct residency: EOF is up to 3x more efficient in zkVMs. When this upgrade lands, real-time proving of Ethereum blocks will definitely be possible.
✍️ Trading Crypto in the Dark 👉Read(EN)
In traditional equity markets, dark pools have long provided a discreet avenue for handling large trades, shielding them from public view to minimize market impact. These private venues allow institutional investors to execute sizable orders without tipping off the market, reducing the risk of adverse price movements that might occur if order flows were visible. Yet, in the realm of cryptocurrency—where transparency, decentralization, and state provenance are foundational principles—this approach raises a fundamental question: is it possible to create a “dark” market structure in a space that thrives on openness? This tension between the privacy of dark pools and the transparency ethos of blockchain technology presents both a challenge and an opportunity for innovation in crypto markets.
