Slide 2 www.dlt-talents.com/ What is Web 3.0? “Web 3.0” is used to describe the next generation of the internet characterized by its features such as ubiquity, decentralization, autonomous, artificial intelligence, and semantic web interactivity. Web 1.0 vs Web2.0 vs Web3.0 Picture: Difference Between Web 1.0, Web 2.0, Web 3.0 - IMPACTMILLIONS

Slide 3 www.dlt-talents.com/ Difference Between Web1.0 / Web2.0 / Web3.0 Feature Web 1.0 Web 2.0 Web 3.0 Timeframe 1990s to early 2000s Mid-2000s to present Expected in the 2020s User Focus Passive Interactive, participatory Proactive, anticipatory Content Static HTML pages Dynamic, user-generated Intelligent, autonomous Technology Client-server model, Basic HTML, No mobile support APIs, Cloud computing, Mobile optimization DLT/Blockchain, AI, Machine Learning, IoT, Cloud Computing, AR/VR Communication Email, Static websites Social media, blogs, Instant messaging, Video conferencing Multi-dimensional, Seamless Examples Yahoo, AOL, Netscape, GeoCities Social media: Facebook, Twitter, YouTube, LinkedIn BaaS, Blockchain-based Marketplaces, Metaverse, Decentralized SNS

Slide 4 www.dlt-talents.com/ Difference Between Web 3.0 / Web3 Strictly saying, Web3 and Web 3.0 are not the same thing. Web3 Web3 is a generic term that represents the vision for a better Internet. The decentralized web or web3 puts a strong emphasis on security and empowerment by returning control of data and identity to users. Web3.0 The semantic web or web 3.0, focuses on efficiency and intelligence by reusing and linking data across websites. The Semantic Web is advocated by Tim Berners-Lee, who is one of the creators of the Web. In general, when referring to blockchain technology, it can be appropriate to use "Web3" instead of "Web3.0". “Web3” is considered as a movement for creating new value based on blockchain technology.

Slide 5 www.dlt-talents.com/ What are the different use cases for NFTs? How can they look? Twitter founder Jack Dorsey’s first tweet sold for $2.9M to a Malaysia-based businessman. The price of each character is roughly $100k. The profits generated by this NFT were donated to the GiveDirectly Africa fund. A tweet picture can be sold as an NFT Keyword: NFTs for Good (raising funds for social good) Man who paid $2.9m for NFT of Jack Dorsey’s first tweet set to lose almost $2.9m | Twitter | The Guardian Sold for $2.9M

Slide 6 www.dlt-talents.com/ NFTs NFTs can represent digital or real-world items like artwork, real estate, and even individuals' identities and property rights. ・Non-fungible token (NFT) is a unique digital identifier recorded on a 　blockchain. Used to certify ownership and authenticity ・NFTs cannot be copied, substituted, or subdivided ・The ownership of an NFT is recorded in the blockchain and can be 　transferred from the owner, allowing NFTs to be sold and traded Many things in the world can be represented by NFTs Music Art Book Machine Certificate Car Real estate Game Items Flight ticket Membership

Slide 7 www.dlt-talents.com/ NFT Sales Volume T Top3: Ethereum, Solana, Polygon in April 2023 ・Ethereum tops trading volume despite its rising gas prices (accounts 70%) ・Solana’s growth is skyrocketed since Solana has just started in 2020 ・Polygon (layer2, sidechain of Ethereum) offers advantages: lower gas costs (almost free), faster transaction times, increased scalability 2023 NFT Market Analysis: An Insider Look | CoinMarketCap

Slide 8 www.dlt-talents.com/ Metaverse “3D Internet” - A metaverse is a collective virtual shared space, created by the convergence of virtually enhanced physical and digital reality. ・The metaverse will provide new business opportunities, better collaboration, and improved mental health (also consider the negative side) ・The metaverse enables a virtual economy using digital currencies and non-fungible tokens (NFTs).

Slide 9 www.dlt-talents.com/ Hosting Metaverse Event in Spatial: I personally enjoy creating Metaverse space using Spatial (I have a background in 3D mechanical model design previously) I have organized an anniversary event for our online cake shop. Customers played together on virtual cakes. Sweets Suites (sweets-suites.com)

Slide 10 www.dlt-talents.com/ My opinion of the top 5 use cases My top 5 use cases for Distributed Ledger Technology (DLT): 1. Manufacturing / MOBI (Automobile) 　 Keywords: Fraud prevention, Reduced Risk, Improved Efficiency Having a background in the technology industry, adoption of DLT technology in manufacturing sector is a key area of focus for me. The concept of decentralization across different systems, locations, and people (nodes) will deliver trust, transparency and security through DLT’s immutable feature. 2. Entertainment & Art / Opensea DLTs create opportunities for artists to receive royalties for their work. Smart contracts can be programmed to automatically pay the artist a percentage of the sale price each time the NFT is resold. Use case: Opensea

Slide 11 www.dlt-talents.com/ My opinion of the top 5 use cases for DLT 3. Education / Student records and financial aids 　DLT enables to create secure and transparent records of student achievements and credentials. This immutable record could help reduce fraud and improve accountability. Also, DLT can streamline administrative processes, such as student registration and financial aid distribution via using secure records. 4. Real Estate / Tokenization Dividing real estate assets into smaller units can be represented by digital tokens. It enables broader participation and investment opportunities. 5. Government / e.g. KSI Blockchain in Estonia DLT can enhance transparency and security in government processes and voting systems. A decentralized and immutable ledger is a key to ensure data integrity and security.

Slide 12 www.dlt-talents.com/ What I can recommend to read and learn What Is a Dynamic NFT and How Does It Change Over Time? | Binance Academy Article from Binance: “What Is a Dynamic NFT and How Does It Change Over Time?” Unlike static NFTs, dynamic NFTs’ metadata can be changed and visually translated. While static NFTs are typically created using the ERC-721 token standard, dynamic NFTs are designed using the ERC-1155 token standard. Dynamic NFT will be used for used car sales, property sales and personal ID etc., Dynamic NFTs: ・ a sub-category of NFTs ・ characteristics can be altered ・ contain information called metadata, which describes its characteristics
