A new collaboration between ChainGPT, an AI company specialising in blockchain development tools and Secret Network, a privacy-focused blockchain platform, is redefining how developers can safely build smart contracts with artificial intelligence. Together, they’ve achieved a major industry first: an AI model trained exclusively to write and audit Solidity code is now running inside a Trusted Execution Environment (TEE). For the blockchain ecosystem, this marks a turning point in how AI, privacy and on-chain development can work together.
For years, smart-contract developers have faced a trade-off. AI assistants could speed up coding and security reviews, but only if developers uploaded their most sensitive source code to external servers. That meant exposing intellectual property, confidential logic and even potential vulnerabilities. In an industry where trust is everything, this risk held many teams back from using AI at all.
ChainGPT’s Solidity-LLM aims to solve that problem. It is a specialised large language model trained on over 650,000 curated Solidity contracts, giving it a deep understanding of how real smart contracts are structured, optimised and secured. And now, by running inside SecretVM, the Confidential Virtual Machine that powers Secret Network’s encrypted compute layer, the model can assist developers without ever revealing their code to outside parties.
“Confidential computing is no longer an abstract concept,” said Luke Bowman, COO of the Secret Network Foundation. “We've shown that you can run a complex AI model, purpose-built for Solidity, inside a fully encrypted environment and that every inference can be verified on-chain. This is a real milestone for both privacy and decentralised infrastructure”.
SecretVM makes this workflow possible by using hardware-backed encryption to protect all data while computations take place. Developers don’t interact with the underlying hardware or cryptography. Instead, they simply work inside a private, sealed environment where their code stays invisible to everyone except them—even node operators. For the first time, developers can generate, test and analyse smart contracts with AI while keeping every detail confidential.
This shift opens new possibilities for the broader blockchain community. Developers gain a private coding partner that can streamline contract logic or catch vulnerabilities without risking leaks. Auditors can rely on AI-assisted analysis while keeping sensitive audit material protected. Enterprises working in finance, healthcare or governance finally have a path to adopt AI-driven blockchain automation without raising compliance concerns. Even decentralised organisations can run smart-contract agents that make decisions privately, without exposing internal logic on a public chain.
The system also supports secure model training and fine-tuning on encrypted datasets. This enables collaborative AI development without forcing anyone to share raw data—a meaningful step toward decentralised and privacy-preserving AI at scale.
By combining specialised AI with confidential computing, ChainGPT and Secret Network are shifting the trust model of on-chain development. Instead of relying on centralised cloud AI services, developers now have a verifiable, encrypted environment where they keep full control of their code, their data and their workflow. It’s a practical solution to one of blockchain’s biggest challenges: using powerful AI tools without sacrificing privacy.
As the technology evolves, the roadmap includes confidential model fine-tuning, multi-agent AI systems and cross-chain use cases. But the core advancement is already clear: developers now have a way to use AI for smart contract development that is fast, private and verifiable—without compromising the security standards that decentralised systems rely on.

Turning the subtle power of nostalgia into meaningful marketing.
Think of nostalgia as a time machine for brands—it doesn’t just take people back; it brings their emotions forward. And emotions sell. For those who are unfamiliar, nostalgia marketing is a strategy where brands use elements from the past—like familiar sights, sounds, or stories—to evoke warm memories and emotional connections with their audience.
This emotional pull isn’t just anecdotal—research shows its real impact: according to The Team and Forbes via The Drum, 80% of millennials and Gen Z are drawn to brands tapping into nostalgia, while 92% of consumers say nostalgic ads feel more relatable. And for startups competing in noisy markets, this is a goldmine.
In this article, we’ll explore why nostalgia marketing can be a game-changing strategy for your company.
Out of all the popular marketing methods—like influencer partnerships or attention-grabbing ad campaigns—nostalgia is unique because its impact starts intrinsically, in the brain. By triggering the release of dopamine, a reward-system neurotransmitter, Nostalgia evokes feelings of warmth, happiness and comfort. Consequently, people don’t just remember a moment—they relive it. Take, for instance, your favorite cereal brand bringing back childhood cartoon characters or using retro fonts and colors. You might choose it over a healthier breakfast option simply because it reminds you of the mornings you enjoyed as a kid. Similarly, speaking of stirring fond memories, Coca-Cola has mastered this effect, using classic holiday ads, vintage packaging, and iconic imagery. Those associations make people see Coke as more than a drink—it’s a familiar feeling they’re willing to pay extra for.
New marketing campaigns can spark curiosity but often trigger skepticism—especially when audiences lack prior connection to the brand. Nostalgia marketing breaks down this barrier by tapping into familiarity, using retro jingles, vintage fonts, pastel colors, or familiar packaging that immediately resonate. This recognition builds an emotional connection and trust with the brand. More importantly, it fosters social connectedness by making consumers feel part of a larger community—giving that reassuring “others remember this too” feeling. As a result, this sense of belonging reduces loneliness, strengthens warmth and trust, and encourages word-of-mouth sharing, naturally amplifying the campaign’s reach and impact.
While luxury brands can afford massive campaigns, startups and small businesses can tap into nostalgia as a cost-effective storytelling tool. In a world where marketing often chases the “next big thing”—from AI to futuristic tech—nostalgia offers the opposite: a chance to revisit the past. More importantly, nostalgia allows brands to stand out in a crowded, fast-scrolling feed by delivering something comfortingly familiar with a fresh twist. Think of Polaroid: in an age where smartphones boast crystal-clear cameras, it wins hearts with pastel hues, a vintage lens, and the tactile charm of instant prints—selling not just images, but a moment that feels straight out of the past.
The same principle worked brilliantly for Tiffany & Co., whose 185-year-old brand refresh featured Jay-Z and Beyoncé in a Breakfast at Tiffany’s-inspired campaign, blending timeless charm with contemporary star power and racking up millions of views. In essence, when done right, nostalgia doesn’t just market a product—it invites people to relive a story they already love.
Nostalgia resonates across generations speaking to diverse audiences. For Millennials, it’s a chance to relive the cultural touchpoints of their youth, while Gen Z approaches it with curiosity, eager to explore eras they never experienced firsthand. This crossover creates a unique marketing sweet spot: one group is driven by memory, the other by discovery. Pokémon proves this power by keeping lifelong fans engaged through retro trading cards while introducing younger audiences to its history. Similarly, Nike used nostalgia to bridge two different generations by reissuing retro classics, keeping both longtime fans and new sneakerheads excited. By appealing to both memory and curiosity, brands can create lasting connections that keep different generations engaged at once.
Nostalgia can be your startup’s non-cliché marketing mantra. Imagine a small bookstore that offers handwritten recommendation cards designed like vintage library checkout slips. This simple touch invites customers to slow down and rediscover the joy of reading. Or picture a local coffee shop serving drinks in mugs inspired by classic diner ware, evoking comforting memories of simpler times. Overall, the lesson is clear: combining nostalgic design with stories that connect people to shared moments creates emotional warmth and trust. Thoughtful nostalgia turns everyday products into meaningful experiences—building loyal communities eager to return.
