A decentralized social learning network for calculus

Our mission is to improve the quantity and proficiency of calculus students in the U.S. We plan to achieve this by developing the 345pi decentralized social learning tool — a network with the potential to disrupt how calculus content is created and learned.

The 345pi project creates a decentralized social learning network that uses Ethereum-based ERC-20 tokens and ERC-721 NFTs to reward members for using, creating, and curating collaborative calculus content. Innovative content that delights fellow members can lead to meaningful monetization for successful creators. The tool is accessible through 345pi.net by connecting a digital wallet such as MetaMask.

Our approach builds on research into visual and collaborative techniques for calculus education — including the neuroscience and mathematics-education work of Stanford Professor Jo Boaler, which shows the importance of collaboration and immersive visualization in teaching mathematics.

Our main product is Tiny Cards, a spaced-repetition system with augmented reality. The key idea behind spaced repetition (Pimsleur, 1967) is to reintroduce ideas and problems before learners forget them — forcing engagement, mistakes, correction, and memory refresh. Research in Applied Cognitive Psychology (Emeny et al., 2021) shows spaced practice can produce higher scores than massed practice in school mathematics.

A second key concept is augmented reality, where complex formulas are presented visually — for example, integration as infinitely many small rectangles under a curve, or moving visualized cones to form a cross-section. The content focuses on fundamental understanding (definitions, proofs, motivations, conditions) rather than surface-level facts, preparing students for advanced STEM coursework.

Our benchmark is Duolingo, whose spaced-repetition language platform reached 37M monthly active users — proof of the model in language learning. 345pi aims to pioneer the equivalent for spaced, visual mathematics, with an ultimate goal of a "345pi Proficiency Score" as an alternative to the AP Calculus test.

Two ERC-20 tokens power the platform: $345P, the utility currency for playing, creating, and tipping modules, and $345G, the governance token representing treasury stake and voting power.

The platform launches with a Member-NFT-gated model: $345P, $345G, and 345pi NFTs can only be traded with other Member-NFT holders — transactions with non-member wallets fail. This keeps content within the community's control. The treasury is held in a multi-signature wallet requiring at least two Dark Lords to approve any outgoing transaction, and a wallet-address-based referral system keeps referral codes unique and verifiable on-chain.

Target: a subscription base of 10,000 members and roughly $1M in ETH-equivalent first-year revenue. Governance runs on $345G via snapshot.org, where members create and vote on proposals — including which modules are approved to the network. At the end of each year, members can vote to continue the platform or liquidate the treasury, distributing ETH pro-rata to $345G holders. The project starts centralized (Dark Lords hold all distributed $345G) and decentralizes as tokens flow to high-performing students and creators.

The Duke University Math department estimates ~700,000 students are enrolled in college-level calculus in the U.S. each year — roughly 100,000 in AP high-school courses, 125,000 in two-year colleges, and the remainder in four-year colleges and universities.
