# Ethereum Founder Vitalik Unveils Crypto’s “Final Boss”: This Technology Could Change Everything > Ethereum co-founder Vitalik Buterin describes indistinguishability obfuscation (iO) as the "final boss" of cryptography, a technology that could revolutionize blockchain privacy and voting systems once its "galactic" computational requirements are overcome. **Ethereum (ETH) co-founder Vitalik Buterin described cryptographic obfuscation technology as the “final boss” of cryptography, stating that this method is currently too complex for practical use.** **Ethereum (ETH)** visionary **Vitalik Buterin** shed light on one of the most challenging goals in the world of cryptography in his newly published blog post. Buterin defined the technology known as **indistinguishability obfuscation (iO)**, which allows a program’s code to be hidden while it continues to function, as the greatest hurdle to be overcome. This technology aims to execute transactions securely without revealing the content of the data. According to Buterin, when combined with **blockchain** technology, this method could pave the way for completely trustless third-party protocols. This technology, which carries the potential to revolutionize areas such as private and tamper-resistant **voting systems**, almost entirely eliminates the need for a central authority. However, Buterin emphasized that current mathematical models and computational requirements are of “galactic” proportions and are not yet applicable in the real world. ### A New Era in Cryptography: iO Technology Buterin presented three different roadmaps for solving this complex structure. First, the famous developer stated that current **lattice-based** designs—which store data within complex geometric structures—must be optimized, comparing this process to the development of **SNARK** technology in 2010. He predicts that with powerful graphics processors, the time required for these operations could be reduced to as little as one day in the future. Other options include making bolder cryptographic assumptions or discovering entirely new non-lattice-based methods. Stating that this research is critical for the future of the **Ethereum** ecosystem, Buterin expressed that developing this technology requires bringing together almost all the tools cryptography has invented in the last twenty years. Reminding that the runtimes of current systems could even exceed the lifespan of the universe, Buterin added that there is still a long way to go before theoretical security translates into practical application.
