🚀 TSUNAGI Propagation Milestone Achieved Today our Zig-built node TSUNAGI successfully served a block to a live Cardano preview relay using the full Node-to-Node protocol stack. Handshake → ChainSync → RollForward → BlockFetch → BatchDone Logs confirm: • FindIntersect = found • BlockFetch RequestRange • StartBatch / BatchDone • served_header = true • served_block = true A Zig implementation acting as a real Cardano peer. Not a simulation. Not a parser. A node. Next phase: • continuous propagation • historical ancestry coverage • light-node mode • operator tooling (JP-friendly) #Cardano #Zig #Cardanonode #Tsunagi

thank you so much for tuning in for another great episode! We just uploaded the archive. youtu.be/qXvh3U-thno

Five months ago TSUNAGI was just an idea. No grants. No treasury funding. No VC money. No paid engineering team. Just a belief that Cardano deserves independent builders willing to take risks, fail publicly, learn, and keep going. We started on Zig 0.13. Then Zig 0.15. Today TSUNAGI runs on Zig 0.16. The journey was anything but smooth. We fought through era mismatches, sigma drift, opcert failures, stale parents, propagation issues, delivery bugs, and countless nights staring at logs wondering what we were still missing. Every time we solved one problem, another appeared behind it. There were moments when quitting would have been the easy option. But today, for the first time, I can honestly say: TSUNAGI is no longer missing blocks. That isn't because we got lucky. It's because we stayed in the fight long enough to find every reason we were failing and fix it. More importantly, I want to say thank you. Thank you to everyone who delegated to TSNG on Preview. Thank you to everyone who followed the journey. Thank you to everyone who believed in us when there was nothing to show except bugs, logs, and stubborn determination. Those delegations mattered. Those leader slots mattered. Without them we wouldn't have had the real-world data needed to find the next bug, prove the next fix, and keep moving forward. What makes TSUNAGI different isn't just that it's written in Zig. It's the philosophy behind it. We don't hide failures. We document them. We don't move on from bugs. We understand them. We don't treat mistakes as something to forget. We turn them into tests so they never happen again. Every failure becomes evidence. Every bug becomes a regression test. Every setback becomes part of the system's memory. While many people are focused on funding, proposals, and treasury discussions, I wanted to prove something first: You don't need permission to build. You don't need a budget to innovate. And you don't need to wait for someone else to solve the hard problems. You can sit down, do the work, and keep going until it works. Today I'm proud of what TSUNAGI has become. But I'm even more proud that we never gave up before getting here. This isn't the finish line. It's the beginning. The real work starts now. 🚀🎌 Thank you for believing in us. #Cardano #TSUNAGI #ZigLang

さぁ、やりますか、ジャパン🇯🇵

Still pushing hard on TSUNAGI, trying to make it consistently forge and behave correctly on Preview. Every day I'm hitting the faucet, hoping for enough funds to get a few more shots at leader slots and gather more real-world data. Slowly but surely, we're getting there. That said, being an SPO is getting harder and harder. I recently lost another delegator, and honestly, I've started asking myself whether I should continue as an SPO at all. Not because I don't believe in Cardano, but because the economics are becoming increasingly difficult for a small independent operator. The reality is that I'm building a node. Testing, validating, and iterating requires opportunities to forge blocks. When you're only seeing a handful of leader slots, progress naturally takes time. That's just part of the journey. Then there are the practical realities: server costs, infrastructure costs, and the fact that everything seems to be getting more expensive while the broader crypto market remains challenging. As a solo builder, I have to make smart decisions. At the same time, I still believe node diversity matters. I still believe Cardano benefits from independent operators and alternative implementations. That's the reason TSUNAGI exists in the first place. Whether I ultimately remain an SPO or not, TSUNAGI itself is moving forward. The mission hasn't changed. Every observation, every leader slot, every test, every failure, and every breakthrough teaches us something new. So for now, I keep building. No time for whining—that's for sure. Maybe this post is just a little stress relief after a long day of debugging, testing, and chasing the next piece of truth. 😂

😁great place to start my morning❣️

‘JAPAN REPLIES TO CARDANO’ Thank you so much to everyone who joined yesterday’s SPACE. First of all, huge respect to @hix_coffeepool for hosting and carrying the conversation all the way through, and thank you as well to @Hardfork_OT for speaking about Catalyst GRAPH APP that you have made! Honestly… I never expected so many people from around the world to gather together like that. Before the SPACE started, there was a part of me wondering: “Will Japan’s voice really be heard?” “Does the global community even care what’s happening here?” But yesterday answered that clearly. People from all over the world came because they genuinely wanted to understand what is happening inside the Japanese Cardano community. That alone meant a lot. For some reason I couldn’t even join properly through @AshiyaPool and had to jump in through @_Night_Forge_ instead🤣 but honestly, that chaos somehow made the SPACE feel even more real. It wasn’t polished. It wasn’t perfectly organized. There were disagreements, emotions, and tension at times. But that is exactly why it mattered. On X, people argue every day. Communities split apart. Different sides attack each other. Sometimes it feels impossible to have a real conversation anymore. But yesterday, people from completely different perspectives actually sat down and talked. That was powerful. And more than anything else, I was reminded how much love people still have for Cardano. The passion. The belief. The willingness to fight for the future of this ecosystem. Seeing that again made me realize something very important: Cardano is not finished. Not even close. If anything, this feels like the beginning of a new chapter. And having @IOHK_Charles come into the SPACE himself and speak directly and passionately also meant a lot. Whether people agreed or disagreed, the fact that both sides could speak openly in the same place was important. At the same time, Japan absolutely has problems we need to face honestly. There are divisions. Closed circles. Power structures. A lack of fresh participation. And serious manpower problems around the current DRep ecosystem. There is still a lot of “darkness” inside the Japanese Cardano scene that has not fully surfaced yet. But yesterday was not just about blaming people. It became a place where we could seriously ask: “How do we move closer to true decentralization?” And personally, I believe some of the current structures in Japan need to be broken apart completely. Not out of hate. Not to destroy Cardano. But because decentralization cannot survive if power, influence, and decision-making become stagnant. New builders need space. New voices need room to speak. People who are actually creating value need to be seen. Nobody gives us decentralization for free. We have to build it ourselves. That is why even without funding, even without treasury money, I continue building. We are still building nodes. Still building infrastructure. Still trying to push Cardano forward from Japan. Yesterday’s SPACE felt bigger than drama or controversy. It felt like the beginning of a new era for Cardano Japan. To everyone who spoke. Everyone who listened. Everyone who joined from around the world. Thank you from the bottom of my heart. And trust me… this conversation is only getting started. There’s still a lot more to say. See you all in the next SPACE.

『JAPAN REPLIES TO CARDANO』 昨日のSPACE、本当にたくさんの方に集まっていただきありがとうございました。 まずはホストとして最後まで走り切ってくれた @hix_coffeepool さん、本当にお疲れ様でした。 そして @Hardfork_OT さんもCatalystや今のCardanoについてのリアルな話をありがとうございました。 正直、ここまで世界中から人が集まるとは思っていませんでした。 SPACEを開く前は、 「日本の声なんて届くのか」 「ちゃんと伝わるのか」 そんな不安もどこかにありました。 でも蓋を開けてみれば、 本当に世界中のCardanoコミュニティが “今、日本で何が起きているのか” を真剣に見ていた。 それを改めて強く実感しました。 僕自身、なぜか @AshiyaPool では入れなくなってしまい、 急遽 @_Night_Forge_ 側で参加するというハプニングまでありましたが（笑） 逆にそれも含めて、すごく「生っぽい」SPACEだった気がします。 綺麗事だけじゃない。 でも、だからこそ意味があった。 X上では日々いろんな意見が飛び交っています。 時には対立もあるし、 感情的になることもある。 でも昨日は、 普段ぶつかり合っている側の人達が、 ちゃんと同じ場所で話をすることができた。 それが本当に大きかったと思っています。 そして何より、 世界中から集まってくれた人達の“Cardano愛”が凄かった。 ここまで真剣に議論し、 ここまで熱量を持ち、 ここまで未来を信じている人達がまだこんなにいる。 それを見て、 「Cardanoはまだまだ終わっていない」 どころか、 「ここからまた始まる」 そう強く感じました。 さらに、 @IOHK_Charles さん本人が来て、 しっかり自分の言葉で熱く語ってくれたことも、 とても大きな意味があったと思います。 もちろん、 日本コミュニティには課題もあります。 閉鎖感、 分断、 情報格差、 一部の権力構造、 DRepのマンパワー問題。 まだまだ表に出ていない“日本の闇”もあると思っています。 でも昨日は、 ただ誰かを叩く場所ではなく、 「どうすれば本当のdecentralizedに近づけるのか」 をみんなで考える場所になった。 それが本当に嬉しかった。 そして僕は、 今の日本のDRep構造や、 固定化された空気感、 古い流れを、 本気で壊していかなければいけないと思っています。 壊すというのは、 ただ否定することじゃない。 新しい人が入れる空気を作ること。 本当に価値ある挑戦者が埋もれないようにすること。 そして、 “みんなのCardano” をちゃんと取り戻すこと。 decentralizedは、 誰かが与えてくれるものじゃない。 一人一人が、 声を上げ、 議論し、 動いて、 初めて作られていくものだと思っています。 僕自身、 Fundingも受けず、 泥臭く、 それでも信じてノードを作り続けています。 だからこそ、 理想論だけじゃなく、 実際に動く人間として、 これからも前に立っていきたい。 昨日のSPACEは、 単なる炎上や議論ではなく、 “Cardano Japanの新しい時代の始まり” だった気がしています。 改めて、 来てくださった全ての方、 聞いてくださった全ての方、 発言してくださった全ての方へ。 心からありがとうございました。 そしてこれは、 まだ始まりに過ぎません。 言いたいことはまだまだ山ほどあります。 続きは、また次回のSPACEで。 本当にありがとうございました。
