With the basics of Corda under your belt we will take you to the next level of your Corda distributed application (CorDapp). In this boot camp we’ll help you learn how to use tokens capabilities. Tokens give developers the ability to represent fungible assets on the ledger. The token SDK does much of the heavy lifting for you on the logic needed for issuance and management of tokens. This capability gives developers a fast way to create tokenized assets on Corda with real-world business use cases supported.

2. Quick Recap: Components of a CorDapp
2. Contract:
Verify the transactions
3. Flow:
Execute the business logic
1. State:
The object in Corda State
1. Get consumed
2. Get updated
3. Get stored

3. What is Token…
• A token is a representation of an asset.
Physical Tokens Digital Tokens
Cryptocurrencies Tokenized Asset

4. What is Token on Corda?
• It is not a cryptocurrency
• A digital representation of asset ownership
• A bearer instrument represents liability between
the issuer and owner

5. A Tokenized Economy on Corda…
• Maximum Security
• Peer-to-peer transactions over a decentralized network providing the
highest security.
• Simple Traceability
• Users can retrieve a credible history of any ledger asset with confidence.
• Increased liquidity & Market Access
• Illiquid assets can now be represented and traded (as a whole or
fractionally) over markets, enabling new sets of owners.

6. Under the hood of Corda TokenSDK
• TokenSDK Overview
• Fixed vs Evolvable Tokentype
• Fungible vs Non-fungible Tokens
• Token Management

7. Corda TokenSDK
• TokenSDK provides a standard library to create and manage tokens in Corda.
ISSUE
MOVE
REDEEM
CREATE Creates the underlying TokenType for the token (Fixed or Evolvable)
Issues the tokens to the designated holders
Moves the tokens around the network
Destroys the token representation and claims the asset itself

Fungible House Token:
This CorDapp serves as a basic example to create, issue, move fungible tokens in Corda utilizing the
TokenSDK.
Stock Pay Dividend:
This CorDapp aims to demonstrate the usage of TokenSDK representing stock. The StockState stores the
stock details(dividends percentage) which can be updated over time.
Bike Market:
This sample CorDapp demonstrate create, move, and redeem actions of the tokenized asset.
