How Cryptography Innovation Became the Core of Sui Design

Recently, a co-founder and chief Cryptography expert of a blockchain company shared how cryptography innovation has become the core of the company's blockchain design and why the upcoming features are exciting.

The Role of Cryptographers in Building Blockchain

Cryptographers usually play three key roles in blockchain infrastructure companies:

1. Research: Innovate in Cryptography, seek new algorithms, and study how to break algorithms.

2. Implementation: Apply Cryptography concepts to design and implement new features based on product requirements.

3. Innovation: Propose new ideas and products based on existing Cryptography primitives.

These three roles often require collaboration among multiple people. A typical blockchain Cryptography team usually consists of around 10 people working together towards innovation and implementation.

External Research Progress and Internal Innovation

The evolution of external signals such as zero-knowledge proofs and privacy protection technologies proposed by the academic community has impacted the company's Cryptography research. The company excels at integrating these new theories with existing technologies to drive the birth of innovative products.

For example, the zero-knowledge login feature developed by the company is the result of internal innovation based on external technologies. The company not only focuses on theoretical research but also emphasizes putting innovation into practice, transforming it into actual functionalities on the blockchain.

Internal innovation is often triggered by the product team. When faced with problems that existing research cannot solve, the Cryptography team seeks innovative solutions through brainstorming and other methods.

Move Language Empowers Cryptography Innovation

Move language has many advantages in terms of security and functionality compared to traditional smart contract languages like Solidity.

1. Natural defense against reentrancy attacks
2. Object-oriented design improves code reusability
3. A clear object structure enhances transaction security.
4. Support parallelization, which is beneficial for designing efficient algorithms.

These features make Move an ideal tool for building Cryptography innovations. For example, companies utilize Move to develop a reusable random number generation system that can be applied in various scenarios such as lotteries and games.

Advantages of On-Chain NFT Storage

The company advocates for storing NFTs on-chain to achieve dynamic updates and better composability. The advantages of on-chain storage include:

1. Supports dynamic NFTs, with attributes that can be updated in real-time during transactions.
2. Reduce storage costs and facilitate on-chain read and write
3. Simplify the interaction between smart contracts
4. Avoid the risks associated with centralized storage
5. Reduce latency and enhance user experience

Future Development Direction

The company will continue to innovate in the following areas:

1. Supports multiple authentication methods to enhance compatibility with existing wallets.
2. Built-in Zero-Knowledge Proof and Privacy Protection Technology
3. Develop more privacy-friendly applications, such as confidential transactions, privacy KYC, etc.
4. Provide Cryptography support for developers to help realize innovative ideas.

Overall, the company will continue to focus on Cryptography innovation to promote the advancement of blockchain technology and the expansion of application scenarios.
