Confidentiality is a crucial aspect of online interactions, ensuring the privacy and security of sensitive information. As web3 continues to evolve, the need for on-chain confidentiality becomes a significant barrier to its widespread adoption. While decentralization and transparency are fundamental to decentralized technologies, absolute transparency may not be suitable for every industry.

Industries such as gaming, payments, identity verification, voting, and finance rely on confidentiality to function effectively. Without it, many potential uses of decentralized applications (dapps) would remain unexplored. For example, user confidentiality is a major concern for individuals and institutions conducting financial transactions. While cryptocurrencies offer improved reliability, they lack the privacy of traditional payment methods. On-chain confidentiality can unlock private yet traceable transactions, addressing user concerns and regulatory requirements like the GDPR.

Similarly, video games require secrecy to maintain an exciting and challenging experience. Implementing confidentiality on blockchain platforms enables hosting a variety of games, expanding the on-chain game library. However, challenges arise from the conflicting interests of data privacy and the prevention of illegal activities like money laundering and fraud.

Current cryptographic methods like zero-knowledge proofs and trusted execution environments have limitations that hinder their effectiveness for on-chain confidentiality. Fully homomorphic encryption (FHE) emerges as a promising technology to provide on-chain composable confidentiality for dapps and web3 protocols. FHE allows the computation of encrypted data without decryption, preserving the confidentiality of sensitive information throughout the process.

While FHE technology is still in its early stages and faces performance limitations, advancements are expected to address these challenges. Web3 solutions with FHE can comply with data privacy regulations and offer security that is resilient against future quantum computing technologies. By addressing the critical issue of confidentiality, the blockchain industry can attract a wider user base and drive adoption across various sectors.

Confidentiality is essential for unlocking the full potential of decentralized technologies and driving adoption. Novel cryptographic protocols like fully homomorphic encryption can create a decentralized ecosystem that empowers users with control over their data without compromising security and reliability.
