Blockchain Rio 2025 Driven by Gaming, Hackathons, and Developer Meetups

Blockchain Rio, Latin America’s largest web3 conference, is set to captivate thousands of attendees in Brazil’s iconic beachfront city this week. The event, hosted at Expo Mag, promises to spotlight developments in RWAs, DeFi, Bitcoin, and institutional finance, with Christ the Redeemer watching over the proceedings. The two-day gathering is expected to feature keynotes, side events, and networking opportunities, all aimed at defining the future of blockchain into 2026 and beyond [1].

Among the standout events, COZ and the NEO ecosystem are bringing “Block Spirits” to life at the ITEM Shop booth. Attendees can collect exclusive AeroGlyph cards, which connect to dapps via smartphone scans, allowing real-time on-chain battles [1]. This initiative highlights a renaissance in the NEO smart contract chain, with AI agents and gaming among its most prominent use cases [1]. The hands-on, frictionless experience aims to showcase the practical side of web3 gaming and blockchain utility.

The Blockchain Rio Hackathon is another major draw, offering rising developers the chance to showcase their skills and gain visibility from potential investors and ecosystem partners. With last year’s event co-hosted by Chainlink and XRP, this year’s iteration is expected to be even larger and more competitive. The hackathon, which begins on August 6, will culminate in a public announcement of winners in front of up to 20,000 delegates at Expo Mag. Prizes and recognition are on the line, making it a must-attend for both seasoned and new blockchain builders [1].

Meanwhile, Starknet is hosting a free meetup in collaboration with OnlyDust and Mediolano, focusing on educational content such as EVMs, ZKPs, and L2s. Attendees can expect an evening filled with technical insights, followed by a social gathering featuring DJ Lazy Eyes. The event is designed to bring together developers interested in open-source blockchain technology, with networking and entertainment running late into the night [1].

Modular House, a Brazilian-focused community meetup, will run concurrently with the Starknet event. Organized by Modular Crypto, it aims to connect local blockchain builders and stakeholders, providing a space for digital assets to meet real-world interactions. Attendees will have the chance to meet representatives from Scroll network, blockchain accelerators, and other key players in the on-chain ecosystem. The event emphasizes community and collaboration, blending professional discussions with casual socializing in a setting where both Portuguese and Python fluency are celebrated [1].

With multiple events running simultaneously and overlapping schedules, attendees are advised to prioritize the four highlighted events. These include the COZ-NEO gaming experience, the Blockchain Rio Hackathon, the Starknet Rio Meetup, and the Modular House community gathering. Alongside keynotes and after-parties, these events are expected to define the conference experience, offering a blend of innovation, education, and entertainment [1].
