PROJECT CASESTUDY Development Project Example 01 01 In developing a blockchain-based IP management platform, we faced the following challenges: - UX with consideration for mass adoption: (e.g., accounting for Issues crypto assets of related companies, Web3 onboarding of creators, etc.) - Balancing Private Chain and interoperability: (Private Chain is appropriate for business requirements, but we want to introduce cross-chain interoperability) Kataru Inc. kataru is a company that aims to create a society in which everyone in the world can participate in culture beyond borders and currency barriers by creating a mechanism to visualize and utilize intellectual property rights that have not been fully utilized through blockchain technology and - decentralized ID technology. Built as a Private Chain with no external Tx influence (only Sunrise DA is used for DA) Solution - Interoperability with the Cosmos ecosystem through IBC support - Tx level customization enables gasless Tx support as a chain

PROJECT CASESTUDY Development Project Example 02 02 - Privacy and Data Regulation: Poop data is treated as biometric data in many countries and is protected by laws such as GDPR. Proper infrastructure is needed to efficiently collect and widely utilize Poop data while protecting user Issues privacy. - Need for standardization: Medical institutions and pharmaceutical companies require Poop data with varying degrees of accuracy and specifications. To accommodate this, it is essential to organize and redefine rules at the Unkomon protocol level. We plan to re-launch UNKOMON as a “Poop Chain,” an infrastructure for collecting Poop data from Poop-to-Earn applications. Aiming to apply web3 to the DeepTech domain, we will collaborate on the following: - PoC for App Chain application to the DePIN space, integrating dedicated private L2 and applications to ensure both privacy Solution and data accessibility. - Joint R&D to build a framework to facilitate the construction of Solana L2 - Proposal for a new token standard for handling biometric data on-chain

WHAT’S SUNRISE DA What’s Sunrise DA The world's first Data Availability Layer supporting both Proof of Liquidity and off-chain Blob. Sunrise is a next-generation data availability layer (DA Layer) that innovatively enhances blockchain processing power and data access. As 100,000 active users within 3 weeks and 200,000 within 6 weeks of testnet launch in July 2024 80,000 followers on official X account the world's first platform combining advanced technologies of Proof of Liquidity and off-chain Blob, it greatly expands the possibilities of modular blockchains. While originating from Japan, it has gained global recognition. Featured on global top development infrastructures like QuickNode and Alchemy

SUNRISE DA FEATURE SUNRISE DA Feature (1/2) Offchain Blob DA Fee Abstraction Proof of Liquidty Data Availability Proof Mechanism through Off-chain Blob DA Fee Abstraction Proof of Liquidty Resolves traditional DA Layer constraints through "off-chain Blob" in conjunction with distributed storage systems (like Arweave). This enables practical implementation of "big block L2s" requiring large-scale data processing, such as AI applications and blockchain games. Developers can use data availability features without initial costs through DA Fee Abstraction. Introduces a mechanism where fees are paid with $vRISE tokens earned from providing assets to liquidity pools, lowering entry barriers while ensuring network liquidity. Grants voting rights to liquidity providers through the unique "Proof of Liquidity (PoL)" system. Unlike traditional Proof of Stake (PoS), it evaluates actual economic activity, establishing a sustainable value creation cycle called the "liquidity flywheel."

SUNRISE DA FEATURE SUNRISE DA Features(2/2) Inter-Blockchain Communication Scalability Native support for IBC Scalability Native implementation of the IBC (Inter-Blockchain Communication) protocol developed in the Cosmos ecosystem. Enables secure data communication and asset transfer between different blockchains, realizing connectivity with a wide range of blockchains including Ethereum. As modular blockchains scale automatically, developers on Sunrise can focus on application development without infrastructure management concerns.
