1. Sign (Sign Protocol)

Basic Introduction:

• Positioning: Decentralized Identity Authentication and Reputation Protocol.

• Goal: Users can record and prove their actions and achievements on the blockchain, creating an 'on-chain resume.'

• Application Scenarios: DAO elections, guild organizations, on-chain job markets (e.g., credit verification for freelancers).

Positive Analysis:

• Rising Demand for Web3 Identity: With the rise of DAOs and decentralized social platforms, 'on-chain identity management' will become one of the infrastructures.

• Trend of Privacy Protection: Sign emphasizes protecting user privacy rather than complete transparency, aligning with future compliance and privacy protection trends.

• Large Potential for Collaboration: Opportunities for integration with social protocols, DeFi protocols, gaming platforms, and other cross-domain areas.

2. Shell (Shell Protocol)

Basic Introduction:

• Positioning: A new type of cross-chain liquidity protocol in the DeFi space.

• Goal: To make asset swaps between different chains faster, cheaper, and more secure.

• Application Scenarios: Cross-chain asset trading, synthetic assets, stablecoin liquidity management.

Positive Analysis:

• Long-term Demand for Cross-Chain: As the multi-chain ecosystem develops (e.g., ETH, BNB, Solana), secure and convenient cross-chain protocols become a fundamental infrastructure need.

• Driven by Cross-Chain Trends like LayerZero: Shell is related to cross-chain concepts and may benefit from the overall sentiment in the space.

• Innovative Design: Introduces mechanisms similar to 'smart routing,' allowing users to experience cross-chain operations close to single-chain operations, showcasing novel technology.

• Opportunity to Leverage RWA Concept: If Shell integrates real-world assets (RWA) in the future, it could also open new markets.
