TezDev 2024 brought in more than 700 attendees and featured names like Arthur Breitman, Justin Drake, and Tarun Chitra—each offering sharp perspectives on where Tezos fits in a rapidly evolving ecosystem. This year, expect more builders, more conversations, and a focus on making things real.

From technical workshops to ecosystem deep-dives, TezDev 2025 will be packed with:

• Panels and demos from teams building on Tezos and Etherlink

• New reveals across gaming, DeFi, and real-world assets

• Networking with developers, designers, and community members

Early bird tickets for TezDev 2025 are now available, and the first 100 will receive exclusive swag at the event, secure your spot here.

Bring Your JavaScript Skills—We’ll Handle the Blockchain Part

Jstz (pronounced “justice”) is a new JavaScript runtime powered by Tezos Smart Rollups, and it's designed for developers who want to build decentralized applications without switching stacks or learning a new language. No special compilers. No custom syntax. Just JavaScript as you know it with access to the transparency, security, and composability of Tezos Layer 2.

You can write smart functions, store data, move tokens, and interact with Tezos infrastructure using standard JS and npm modules all inside a local sandbox that’s easy to spin up and test. And right now, the team is looking for your feedback to help shape Jstz from the ground up.

Jstz is still experimental, but it already lets you:

• Write and deploy smart functions with standard JavaScript.

• Run apps locally with preloaded test accounts and Tezos tokens.

• Use your favorite tools, libraries, and frameworks.

• Explore examples like messaging boards, counters, and full dashboards.

No blockchain experience? No problem. This is a playground for JavaScript developers, not a gated protocol for Solidity pros.

Here’s how to get started:

1. Install the CLI and launch the sandbox.

2. Try the get-tez, show-tez, or counter examples.

3. Deploy a smart function and call it from the CLI or web UI.

4. Submit your thoughts in the Developer Experience Survey.

If you’re among the first to complete the survey, you’ll receive an exclusive Jstz OG NFT.

This is JavaScript for real decentralized apps where your code runs on a rollup, stores data immutably, and scales with Tezos. No wallet integrations yet, no mainnet deployment, but all the tools are there for you to explore what’s possible.

Explore the full docs, examples, and SDKs on the Jstz GitHub.

Let’s build.

This Week in the Tezos Ecosystem

Arthur Breitman Talks L2s, Tezos Upgrades, and Tokenized Uranium at ETHDenver

With TezDev 2025 on the horizon and developers starting to test-drive Jstz, let’s turn our focus to what’s been happening across the Tezos ecosystem this week.

At ETHDenver 2025, Tezos co-founder Arthur Breitman sat down with Genzio CEO for a wide-ranging conversation that covered the current L2 landscape, the ongoing evolution of Tezos, and what it means to bring real-world assets like uranium on-chain.

Arthur unpacked how Tezos is continuing to scale with Smart Rollups and what sets the network apart in terms of governance and long-term architecture. The conversation also spotlighted Uranium.io, the first on-chain uranium marketplace, and how it signals a shift in how we think about tokenizing access to hard assets.

Tezos Gaming Nights: Weekly Streams, Familiar Vibes

As developer activity heats up and protocol upgrades hit the finish line, it’s worth stepping back to see what all that infrastructure enables. One example? Tezos Gaming Nights.

Started by the Tezos Commons team late last year, Tezos Gaming Nights is a weekly livestream that brings Web3 games to life—without all the jargon. Hosted by Blangs and AJ, the stream goes live on Tuesdays at 4:30 PM PST and features two games per session: one built on Tezos and one more familiar to mainstream audiences.

The format is simple and relaxed: no scripted intros, no slide decks—just gameplay. The team kicks things off with a Tezos-native title like Pikes Arena or Auto Hero, talking through what’s happening as they go. If it looks fun, that’s the point. Web3 concepts are baked in, but never front and center.

The second half of the stream usually shifts to something familiar, from Counter-Strike 2 to Once Human. Lately, it’s been the Tezos Community Minecraft Server, a nostalgic, easy-entry game that’s brought new players into the ecosystem without needing wallets or whitepapers. The Tezos Community Minecraft Server is coming alive and guess what we’re building next?

That’s right, we’re building a Uranium mine! In addition to this, other community members have built some incredible creations like a TEIA Marketplace or TED Towers that represent Tezos Domains. We also have artists building their own installations on the server. If you’re interested in joining the server, DM @TezosGaming on X and he will get you situated with your own mailbox.

What sets Tezos Gaming Nights apart is the emphasis on playing, not explaining. It’s not about pitching use cases, it’s about showing what’s already live. If someone can click a link and jump into a Tezos-powered game without thinking twice, that’s the kind of onboarding that sticks.

Want to join the fun? Follow @TezosCommons and catch the next stream this Tuesday. Play, hang out, or just see what’s possible when gaming meets Tezos.

Game Spotlight: Stables

Fresh tracks, new leagues, more strategy—Stables just got a full makeover.

The beta of the updated game is now live, bringing a wave of new gameplay mechanics and visual upgrades that deepen the experience for racers and strategists alike.

Here’s what’s new:

• Revamped UI – A cleaner, smoother interface makes it easier than ever to navigate, race, and manage your stable.

• Leagues System – Horses are now grouped by level, ensuring more balanced matchups and competitive races.

• Dynamic Racetracks – Each league features 3 daily tracks, complete with rotating weather, terrain, and distance conditions every 12 hours.

• Quests – Daily and weekly objectives keep players engaged and rewarded with S-Points and bonuses.

• Power-Ups – Introduce a new tactical layer. Activate boosts at key moments during registration to change your race outcome—especially in higher leagues where multiple boosts can be stacked.

• Mood System – Adds another dimension to race-day decisions, letting players factor in their horse’s mental state for optimized performance.

This update moves Stables toward a more strategic and rewarding racing ecosystem, making gameplay decisions matter more while maintaining its play-and-earn approach.
