<h2><strong>ETHTokyo'25 Hackathon</strong></h2><p>ETHTokyo is an engaging conference and hackathon for the global Ethereum community where people with all sorts of backgrounds, ideas, and skills come together to share their love for Ethereum and its world. Whether you're a seasoned expert or just curious, you'll find friends and inspiration here. Our goal is simple: to connect diverse minds and foster the creation of amazing new innovations for the future. Join our three-day hackathon and collaborate with talented individuals, build innovative solutions, and compete for exciting prizes!</p><p><em><strong>[IMPORTANT] This is an on-site hackathon taking place in Tokyo, Japan. You must purchase our </strong></em><a href="https://app.moongate.id/e/ethtokyo2025" target="_blank"><em><strong>event ticket</strong></em></a><em><strong> to register as an official participant of ETHTokyo'25. Participants of the hackathon will receive 50% refund of ticket price upon successful project submission.</strong></em></p><h2>Goals</h2><p><strong>2025 hacking theme</strong>: <em>Emancipatory Tech for Future of Humanity</em></p><p>Emancipation begins in the mind; let us radically reimagine how we can harness technology to empower people, preserve culture, and build a sustainable future in ways not possible today.</p><p>The goal is to innovate not for its own sake, but to envision new ways and better approaches to do things through reshaping and redefining the constraints of our own constructed reality.</p><h2>Audience</h2><p>Builders, industry professionals, creatives students; anyone is welcome to participate.</p><h2>Hackathon Tracks</h2><h3><strong>🥷 Cypherpunks Anonymous (Privacy &amp; Security)</strong></h3><p>In a world where surveillance and data exploitation have become the norm, privacy is not just a right — it’s a necessity. The Cypherpunk movement emerged to challenge this status quo, using cryptography as a tool to empower individuals to reclaim control over their digital lives. Today, Ethereum provides the perfect platform to extend this vision through programmable cryptography — enabling privacy-preserving applications, secure computations, and anonymous transactions. Cypherpunks Anonymous is a track for builders who share this vision and are ready to push the boundaries of privacy, security, and censorship resistance with cutting-edge technologies like ZKPs, MPC, and FHE. Join us and help shape the future where cryptography safeguards freedom for all.</p><h3><strong>✊ Counterculture Capital (Financial Innovation)</strong></h3><p>Five years after DeFi Summer, we've witnessed the evolution from simple token swaps to sophisticated financial instruments rivaling traditional markets in complexity and capability. From lending protocols to prediction markets that democratize forecasting and information discovery, DeFi continues to drive the ongoing financial revolution. Yet, this revolution is far from complete. As traditional finance continues its slow integration with blockchain technology, DeFi builders are crafting the financial infrastructure that will ultimately bridge these worlds—creating systems that are not only more efficient and accessible than their traditional counterparts but fundamentally more equitable.</p><p>At ETHTokyo, we recognize that DeFi innovation represents the most profound challenge to established power structures in the global economy. DeFi remains the beating heart of Ethereum's revolutionary potential; behind the composable legos and liquidity pools lies a radical vision: financial services that operate without gatekeepers, accessible to anyone with an internet connection, transparent in their mechanics, and governed by their communities rather than centralized authorities.</p><p>This track welcomes builders who share this vision of democratizing access to sophisticated financial tools, who work to reimagine capital efficiency, create robust risk management systems, thoughtfully bridge institutional capital with DeFi principles, bring real-world assets on-chain, extend financial services to the unbanked, or develop governance models that truly embody decentralized ideals—united by a shared vision of transforming finance for greater accessibility and equity.</p><h3>💚 Actually Intelligent (AI &amp; Society)</h3><p>The well-praised technological breakthrough that is Artificial Intelligence faces a dilemma. Behind the convenience it offers, the technology is increasingly being appropriated into manipulative ad engines and corporate-enterprise surveillance. At ETHTokyo, we’re here to flip that. This track embraces AI as a power tool to empower individuals to 10x and 100x, but insists on liberation over manipulation, consent over capture, commons over enclosure. Building systems that make people harder to coerce and easier to coordinate. Private by default. Local-first. Proof-carrying. Forkable. </p><p>Actually Intelligent is a track that leverages the programmability of Ethereum’s decentralized system and the flexibility of AI systems to explore actually intelligent solutions; grounded in the real world, human experience, social dynamics, and lifestyle. Here, we challenge existing paradigms and aim to return to the core values that users truly need.</p><h2>Sponsor bounties</h2><h3>Japan Smart Chain</h3><p>See details: <a href="https://japansmartchain.com/en/landings/eth-tokyo-2025" target="_blank">https://japansmartchain.com/en/landings/eth-tokyo-2025</a></p><h3>ENS</h3><p>See details: <a href="https://docs.google.com/document/d/1FFjoji_eJMS9CIIf92YfXt-z0ro8OCwnWl_2bUZYNFA/edit?usp=sharing" target="_blank">https://docs.google.com/document/d/1FFjoji_eJMS9CIIf92YfXt-z0ro8OCwnWl_2bUZYNFA/</a> </p><h3>ElizaOS</h3><p>ElizaOS is the premier AI agent framework built in typescript, &lt; 3 min quick-start.

<h2>What is ETHTokyo?</h2><p>ETHTokyo is a yearly technology event for the global Ethereum community, offering nonstop technical talks, workshops, hackathons, and side events. We have been doing this since 2023, and around 500 participants come each year to enjoy world-class presentations, demos, community events, and the 3-day hackathon.</p><p><br /></p><h2>Who can attend ETHTokyo?</h2><p>ETHTokyo is targeted to anyone with a creative mind and a hacker spirit (in the classical definition of the word). Anyone with a technical appetite is welcome to apply, not limited to industry professionals.</p><h2>How are applicants selected?</h2><p>ETHTokyo aims to select the best, most participative and motivated, programmers and creatives. For this we rely on you to fill in relevant information in your profiles and questionnaires where we ask. What matters is your potential and your passion for Ethereum, no matter your level of experience.</p><h2>How much does it cost?</h2><p>All participants must purchase our <a href="https://app.moongate.id/e/ethtokyo2025" target="_blank">event ticket</a> for $90, which grants admission to all official parts of the event (conference and hackathon). There is also a discount for students. </p><p>Furthermore, all participants who successfully submit a project on the final day of the hackathon will receive a 50% refund for their tickets after the event.</p><h2>Can I register our company employees in bulk?</h2><p>Event tickets can be purchased in bulk. However, all hackathon participants must register their profile individually.</p><h2>Do you pay for the atendees' transportation and/or accomodation costs?</h2><p>No. However, there may be discounts and other partnerships. If so, these will be announced in the months leading to the event, so make sure you follow us in one of the social networks where we're present.</p><h2>Can I bring a guest to the event?</h2><p>No, all attendees must apply to the event individually.</p><h2>Do I have to participate in the 72h hackathon?</h2><p>It is your choice to participate in some or all parts of the event. However, there is only the full-event ticket, and we do encourage you to participate in something during ETHTokyo, instead of passively roaming around the venue. Fortunately, you have many choices; the conference, the hackathon, and plenty of other side-events to engage with.</p><h2>I was selected but can't attend the event, what do I do?</h2><p>Please let us know. Spots are limited and it would be nice if we could offer another candidate a place instead.</p><p><br /></p><p><br /></p><h2>When will the schedule be available?</h2><p>A detailed schedule will be available closer to the event, on our website</p><p><br /></p><p><br /></p><h2>Will there be a live stream from the event?</h2><p>Yes, live streaming will be available. The feed will be focused on the activities taking place on the main stage, such as talks and contests. When nothing is going on there, you can expect a general transmission of the event.</p><p><br /></p><p><br /></p><h2>Will the talks be recorded?</h2><p>Unless the speaker states otherwise, every talk will be recorded and available online in the weeks following the event.</p><p><br /></p><p><br /></p><h2>Is there food and beverages at the event?</h2><p>Food and drinks will be provided free for all attendees. We'll be providing lunch and dinner daily, and there will be random snacks and beverages available 24/7.</p><p><br /></p><p><br /></p><h2>Why is the official language English?</h2><p>Although around half of our participants are from Japan, we have attendees coming from all over the world. English is usually well understood and accepted. Our main motivation is technology and talent, and these are global attributes, so our main 'language' is what we use to code. English is not the only language at the event, though. The event is bilingual, so there may be talks held in Japanese. These will be properly identified in the event's schedule, as well as accompanied by live translations (automated).</p><p><br /></p><h2>Do I get a participation certificate at the end?</h2><p>Yes, we can provide participation certificates on demand in the days following Cypherpunks Anonymous. Just make sure you actually participate.</p><p><br /></p><p><br /></p><h2>Should I arrange for a place to stay?</h2><p>In the spirit of the event, attendees can choose to stay the night at the venue, sleeping in sleeping bags or such. But if this is not your thing, you have many accommodation options elsewhere around. Closer to the event we may announce discounts and partnerships. Please note that Lisbon has plenty of tourism all year round, which means high occupation in hotels and hostels, so try and book your reservations in advance.</p><p><br /></p><p><br /></p><h2>Are there hotels nearby?</h2><p>Cypherpunks Anonymous's venue (Pavilhão Carlos Lopes) is in a very central location in the city, so there are plenty of hotels around. These are just a few examples: Zenit Lisboa, Lisbon Fontana Park, Hotel Miraparque, Lisbon Top Hostel, Home Sweet Lisbon, Midtown Hostel</p><p><br /></p><p><br /></p><h2>Are there showers available?</h2><p>The logistics for this are complicated, so don't count on it. Bathrooms are available, but showers may not exist at all or be very limited in time. You'll have to improvise.</p><p><br /></p><p><br /></p><h2>I've decided to stay at the venue. Can I bring a small tent to Cypherpunks Anonymous?</h2><p>Although the event has 'Camp' in its name, tents are not allowed due to space limitations inside the venue. However we'll do our best to provide you with optimal spots for taking naps.</p><p><br /></p><p><br /></p><h2>What about a sleeping bag?</h2><p>This one is allowed, no problems with that.</p><p><br /></p><p><br /></p><h2>Is there Wi-Fi at the event?</h2><p>Of course. There will also be a limited number of ethernet outlets in the table area, but teams doing projects for the 48h competition have priority on these.</p><p><br /></p><p><br /></p><h2>Will the Wi-Fi be any good this year?</h2><p>The million-dollar question… The organization will provide a world-class setup but, ultimately, this depends on you and your fellow attendees. Bear in mind that hotspots are NOT ALLOWED at the event. Wi-Fi is a shared medium, like a pool, please don't pee in the pool.</p><p><br /></p><p><br /></p><h2>What are these other activities?</h2><p>The main activity is, of course, the 48h programming competition, where your team works on a project during the event and presents it on stage on the final day. In the Quiz Show teams answer tech/science related questions and in the Security CTF teams try to solve cybersecurity-related challenges. There's also a retro gaming competition where participants play classic games on stage. These are just some examples.</p><p><br /></p><p><br /></p><h2>How can I participate in these other activities?</h2><p>Some will have qualifier challenges in the weeks leading to Cypherpunks Anonymous (eg. the Quiz Show and the Security CTF), you just need to participate and score enough to get qualified. Others require only that you register during the event. Check the pixels.camp website for more details.</p><p><br /></p><p><br /></p><h2>If I'm selected to participate in one of these activities, can I select anyone to team up with me? Even a speaker?</h2><p>Yes, but it'll help if you tell that person beforehand.</p><p><br /></p><p><br /></p><h2>Does that mean I can invite someone who's not attending Cypherpunks Anonymous?</h2><p>No. The other members in your team must also be approved attendees. And to be approved they must apply for the event (individually).</p><p><br /></p><p><br /></p><h2>Are there prizes for winning one of these activities?</h2><p>In most cases, yes. But we won't tell you what the prize is in advance.</p><p><br /></p><p><br /></p><h2>I want to be a speaker at the event. How can I propose a talk?</h2><p>Talks proposals are handled through GitHub pull requests. Follow the instructions in the talks repo ( https://github.com/pixelscamp/talks ).</p><p><br /></p><p><br /></p><h2>Do I need to apply to Cypherpunks Anonymous to propose a talk?</h2><p>Yes, you do. And if your talk is accepted, it means you're immediately accepted as an attendee as well (of course).</p><p><br /></p><p><br /></p><h2>Since english is the official language, should my talk be given in english?</h2><p>English is the official language, yes, but it's optional for participants and speakers. If you're not comfortable (enough) with delivering a talk in english, you can choose to deliver it in portuguese instead. You could also choose Klingon, or Goa'uld, but it makes sense to choose a language that at least a few people in the audience would be able to understand… ;)</p><p><br /></p><p><br /></p><h2>I am interested in exhibiting or becoming a sponsor, what do I do?</h2><p>If you are interested in sponsoring Cypherpunks Anonymous, please contact us at for a prospectus and sponsorship application instructions.</p><p><br /></p><p><br /></p><h2>I'm a tech guy but I also do recruiting. Is it OK if I talk to someone at Cypherpunks Anonymous to see if they're interested in working with me?</h2><p>You cannot engage in direct recruitment activities during Cypherpunks Anonymous. This is one of the core rules of the event. The attendees don't enjoy unsolicited targeting, and we don't want to turn the event into a battlefield for hires. Trust us, it's better for you, not only for attendees. Having said this, it's OK if the interest is mutual and both parties want to talk (meaning the attendee approaches you). It's definitely NOT OK if you're preaching to the crowd or fishing around for interest.</p><p><br /></p><p><br /></p><h2>Can I leave a few flyers on the tables to advertise my group/event/company?</h2><p>That would depend on what you're advertising. The only hard rule on this is that you talk to us first at .</p><p><br /></p><p><br /></p><h2>Still have questions?</h2><p>File an issue on GitHub (https://github.com/PixelsCamp/docs/issues/new?labels=question)</p><p><br /></p><p><br /></p>
