bountyblok
Bountyblok is a versatile gamification platform that provides businesses with a suite of tools to drive user engagement, loyalty, and specific marketing outcomes. Operating as a Software-as-a-Service (SaaS) solution, Bountyblok enables companies to easily integrate gaming mechanics into their existing websites, applications, and communities. The platform allows for the creation of interactive campaigns such as challenges, tasks, leaderboards, and promotional contests, which incentivize user participation and foster a sense of competition and achievement.
While a powerful tool for traditional Web2 engagement, Bountyblok also serves as a bridge to Web3 by offering optional blockchain integration. The platform is chain-agnostic but has a notable integration with the Hedera network. This allows businesses using Bountyblok to reward their users with digital assets in addition to standard points or badges. For example, a user completing a series of challenges could be awarded a commemorative NFT or branded loyalty tokens minted directly on the Hedera network.

Slime World is a play-to-earn (P2E) mobile game developed by NADA Digital. It’s the flagship title published under Hedera Guild Games and is available on Android and iOS. The game leverages the Hedera blockchain platform's speed, low transaction fees, and carbon-negative footprint to offer an engaging blockchain gaming experience where players collect and nurture pets called "Slimes" to protect their world and defend against the encroaching "Dark Slimes."
Players complete quests and embark on adventures to earn in-game currency called "Orichalcon" through various activities. The Orichalon can be exchanged for the Hedera Guild Games (HGG) token (formerly NADA Protocol token) a utility token based on the Hedera blockchain. It can be used within the game for upgrading player’s Slimes, purchasing items to aid in adventures, and creating unique Slime NFTs that can be collected and traded via an in-game marketplace.
Gameplay centers around a strategic tower defense-style "infinite mode" where players take on waves of enemies and a "PVP arena mode" wherein players battle one another using their owned or rented Slime NFTs.
Slime World also features mini-games such as "Super Jump" and "Road Crossing," a roulette system for rewards, enhanced social features including user profiles and global chat, and a built-in multi-staking service for HGG tokens.

Starling Lab for Data Integrity is an academic research center that operates at the intersection of cryptography, decentralized web protocols, and the humanities. A joint initiative between the USC Shoah Foundation and Stanford University's Department of Electrical Engineering, the lab's mission is to develop and prototype tools and principles to establish trust in digital records. In an era of rampant misinformation and AI-generated content, Starling Lab is pioneering new methods to securely capture, store, and verify digital media.
The core of their work is the Starling Framework for Data Integrity, a comprehensive, open-source methodology for authenticating digital content. This framework is built on three pillars: Capture, which involves creating a chain of custody from the moment a photo or video is taken, Store, which uses decentralized networks like IPFS and Filecoin to securely distribute and preserve content, and Verify, which leverages immutable ledgers to register and audit the provenance of digital assets. This end-to-end approach has been applied in various real-world scenarios, from documenting the 78 days of the 2020 U.S. presidential transition with Reuters to preserving the USC Shoah Foundation's archive of 55,000 holocaust testimonies.
