What is web3?

3. • Non-state issued digital assets
reached a combined market
capitalization of $3 trillion in
November 2021
• Same as ASEAN total GDP of the
year 2020

Digital Assets - Rapidly Growing in Value

4. • Mar 09 2022: U.S. : Executive Order By President
• April 04 2022 : U.K.: CryptoAsset Tech Hub by Treasury Dept.
• June 07 2022 : Japan: Basic Policy by Cabinet

Quote “ MAS does not and cannot regulate all products that people put their money in
thinking that they will appreciate in value. “ Unquote
-> Crypto Assets are legal in Singapore

6. Why web3 ? Why “own” ?

7. • Price can increase due to monopoly
• Your data belongs to Platformers
and they exploit your data
(Data Lock-in)
• Even U.S. President’s data can be
erased, without consent, by a company
• Centralisation leads to
Single Point of Failure

What is wrong with Web2?

8. • Your Avatar
• Your Identity
• Your Work space
• Your Money/Wallet

Solution : Blockchain allows you to own your data
Why web3?
Isn’t better for you to own the data in Metaverse?

Evolution of Computation

10. Value is concentrated at the shared protocol layer
TCP/IP, HTTP, SMTP, etc.

NFT (Non Fungible Token)

13. NFT image is stored where ?
{"name":"Gucci Grail Ape #6083",
"description":"In constant pursuit of precious wonders that go beyond the confines of time and space,
Creative Director Alessandro Michele takes a trip <<Deleted>> new era of creativity across dimensions.",

NFT (Non Fungible Token) is defined as contract ERC721 (Coin is
ERC20)

Computation is Not Scalable with current Ethereum
(Gas Limit is the max price user willing to pay for transactions/smart contracts)
Yoshi 15
What is Stopping the Move ? - Lack of Scalability

16. It can take more than 10 hours (600min) to confirm on one transaction with Bitcoin
(Comparison: Visa transaction is 1600 per sec in comparison)
https://www.blockchain.com/charts/avg-confirmation-time
Yoshi 16
What is Stopping the Move ? - Low Speed/Throughput

17. • Treasury Example
• If A and B approves, then coins can be sent to X
• A has privilege to revoke B’ s access
• If A sent 10 coins to B, only then B sent 10 to X
• These rules can be written as Smart Contract and automated fully(This can lead to DAO –
Decentralized Anonymous Organization)
• The automation by Smart Contract will remove the need of “Trust” or “Intermediaries”, called
“Trustless”
• Original meaning of “Trustless” is, “not deserving trust” negative meaning, but in crypto, can be
taken as positive meaning to improve robustness of system by removing the need of “Intermediary”
• Once Smart Contract is executed, it cannot be modified
Yoshi 17
What is Stopping the Move ? - Smart Contract is
Irrevocable, once executed

18. • Sharding is the process of splitting a database horizontally to spread the load. In an Ethereum
context, sharding will reduce network congestion and increase transactions per second by
creating new chains, known as “shards.”
• Creating layers, such as layer1 , layer 2 etc.
e.g. Bitcoin off-loaded to lightening Network as L2
• Layer 2 = can be application specific
• Layer 1 = handling block as source of truh
• Ethereum is moving from PoW to PoS
