Interview with Iron Fish Co-Founder: From Big Tech to Blockchain—Why Privacy Matters
Iron Fish aims to provide private transactions for ordinary users, and is committed to building a platform that prevents abuse while advancing the development of privacy initiatives.
Speaker: Elena Nadolinski, Co-founder of Iron Fish
Privacy is indeed a critical issue, especially in today's technological landscape where advances pose growing threats to personal privacy. While some may believe privacy is gradually disappearing, certain fields and individuals are actively fighting to protect it.
At the forefront of this mission is Iron Fish, a cryptocurrency startup that believes privacy is an essential component of our future. Elena Nadolinski, founder of Iron Fish, recently joined our podcast to discuss the importance of privacy in today’s world, the realities of building a crypto company, and the vision behind Iron Fish.

The Genesis of Iron Fish
When Iron Fish was conceived in 2018, Elena Nadolinski and her team aimed to introduce privacy into blockchain-based cryptocurrencies. They recognized the importance of privacy, particularly amid increasing societal surveillance.
This journey wasn’t straightforward—the team spent months researching existing privacy technologies for public blockchains and potential implementation strategies. They encountered several privacy-focused projects such as Grin, Monero, and Aztec, but observed limitations and usability issues. This led them to decide on building an entirely new blockchain that supports only private transactions.
The Appeal of Privacy
One key question they faced was whether to build a privacy protocol on an existing blockchain or create a new chain from scratch. According to Elena, implementing a privacy solution on an existing chain primarily designed for transparency is difficult, if not impossible. This is because every action taken by users on such chains is visible to everyone, thereby exposing personal information.
This gave rise to Iron Fish—a platform designed to strike a balance. Iron Fish operates on the principle of enabling private transactions for ordinary users while also striving to build a system that prevents abuse and advances the cause of privacy.
The Future of Privacy in Cryptocurrency
Iron Fish’s vision remains unwavering. Elena pointed out that although privacy protocols existed before Iron Fish, it was their unique vision for the world that motivated them to build Iron Fish. As demand for privacy in cryptocurrency grows, platforms like Iron Fish play a crucial role in achieving a balance—being regulatory-friendly, usable for users across multiple chains, and fully delivering value.
Regarding future development plans, Elena shared that Iron Fish is actively working to integrate its cross-chain communication layer to enable Ethereum users to transfer assets easily. They are also optimizing their network layer and redesigning their node application to enhance user experience.
Conclusion
In this era defined by digital activity, we need to rethink privacy, transparency, and the infrastructure that can support these values. Platforms like Iron Fish are committed to creating a future that not only protects privacy but actively champions it.
Despite widespread misconceptions linking privacy closely with illegal activities, the privacy movement continues to face challenges. Projects like Iron Fish are paving the way for a privacy-centric future.
