Confidentiality in Blockchain: Rand Hindi on Zama's Vision and the Future of Onchain Transactions

Summary

Zama is revolutionizing blockchain confidentiality by enabling private, on-chain transactions through a new confidential token standard. The protocol allows users to wrap and unwrap tokens, ensuring privacy while maintaining composability with existing ERC20 tokens. With the upcoming mainnet launch on Ethereum, Zama aims to introduce privacy-first decentralized finance, starting with key apps and expanding to more chains. Their long-term goal is to have 10% of blockchain transactions be confidential, offering a future where privacy is guaranteed by design across all blockchain-based activities.

Takeaways

• 😀 The Zama protocol works by wrapping existing ERC20 tokens into confidential tokens, allowing users to encrypt and decrypt tokens easily for privacy-preserving transactions.
• 😀 Confidentiality on blockchain is seen as essential for widespread blockchain adoption, as it secures users' financial data from public exposure.
• 😀 Zama's testnet launched in July saw overwhelming success, with millions of transactions, but also highlighted scalability issues that are being addressed for the mainnet launch.
• 😀 The Zama protocol’s goal is to have at least 10% of all blockchain transactions be confidential, eventually aiming for 95% of confidential transactions to go through Zama.
• 😀 Zama’s key differentiator is its use of Functional Encryption (FH) to ensure privacy, making it possible for users to perform confidential transactions in a secure, scalable way.
• 😀 The mainnet launch of Zama is planned for the end of September or early October, initially on Ethereum with a few whitelisted apps, expanding to more chains by the end of the year.
• 😀 Zama’s token utility is focused on charging low fees for encrypting and decrypting data, not for computational work, making it a cost-effective solution for privacy-preserving transactions.
• 😀 Zama’s long-term vision is to provide a default confidentiality layer for all digital interactions, not just blockchain transactions, enabling privacy across the internet.
• 😀 Developers and creators can get involved with Zama by accessing the documentation at docs.zama.ai, participating in the creator program, and engaging directly with the team for collaboration.
• 😀 Zama’s confidentiality model could extend beyond payments to various sectors, such as identity services, land registries, and public infrastructure, as part of the blockchain evolution.

Q & A

What is the main goal of the Zama protocol?

The main goal of the Zama protocol is to enable confidential transactions on the blockchain. It aims to provide privacy for users by leveraging Fully Homomorphic Encryption (FHE) to ensure that sensitive transaction details, such as amounts and sender/receiver identities, remain private even while being processed on-chain.

How does Zama's approach to privacy differ from traditional blockchain systems?

Traditional blockchain systems are transparent, meaning that transaction details, including amounts and addresses, are publicly visible. Zama, however, uses confidential tokens powered by FHE to encrypt these details, allowing transactions to be processed in a way that preserves privacy while maintaining blockchain security and transparency.

What is the new token standard that Zama is introducing, and how does it differ from ERC-20 tokens?

Zama is introducing a new token standard called the 'confidential token standard'. This is similar to ERC-20 tokens but designed specifically to support encrypted transactions. Confidential tokens are not ERC-20s but can be converted between regular ERC-20 tokens and confidential tokens through a wrapping process, enabling private transfers while maintaining compatibility with existing blockchain systems.

Can Zama's technology be applied to all blockchain applications?

Zama's technology is focused on providing confidentiality for financial transactions on the blockchain, particularly in decentralized finance (DeFi). While the technology can be used for privacy in payments and asset transfers, the long-term vision includes applying this confidentiality to a wide range of applications, such as government services, identity verification, and even games.

What were the challenges faced during Zama's testnet phase, and how are they addressing them?

During the testnet phase, Zama experienced overwhelming activity, with millions of transactions being processed in just a few days. This led to the testnet infrastructure being overwhelmed, causing some issues. However, this also helped identify weak points, and Zama is working on improving its scalability and robustness to ensure the mainnet launch can support even more confidential transactions.

What is the timeline for Zama's mainnet launch, and what can users expect?

Zama plans to launch its mainnet on Ethereum by the end of Q3 2025, around September or October. Initially, the mainnet will support a limited number of whitelisted applications to ensure high-quality user experiences. By the end of the year, Zama plans to expand to more blockchain networks (L1s and L2s) and allow more developers to access the protocol.

What role does Zama's token play within the ecosystem?

Zama's token is primarily used to pay for the encryption and decryption of data on the network. This ensures that confidential transactions are processed securely. The fee structure is designed to be minimal, and the cost of encrypting or decrypting a transaction is very low compared to regular blockchain gas fees.

How does Zama ensure the scalability of its platform for confidential transactions?

Zama aims to address scalability by improving its infrastructure, particularly through advancements in FHE technology. The goal is to ensure that, by the time of the mainnet launch, Zama can support more confidential transactions than Ethereum can process in general, effectively overcoming the potential bottleneck created by encryption.

How does Zama plan to expand beyond financial transactions into other areas like identity and government services?

Zama's long-term vision includes extending its confidential transaction technology beyond just finance. It envisions using its encryption methods to secure sensitive data in applications like identity verification, land registries, tax systems, and even gaming. The aim is for privacy to be guaranteed by design in these services, much like the way blockchain provides transparency.

How can developers and users get involved with Zama's ecosystem?

Developers can get started by accessing the documentation on Zama's website (docs.zama.ai), where they can learn how to build confidential applications. Zama also has a creator program for individuals who want to engage with and help spread awareness about the project. Additionally, the community is encouraged to reach out directly via social media or through personal contact with the Zama team.
