Distributed Ledger
Technology (DLT)
➔ Each node holds a copy of the
ledger
➔ Blockchain + P2P+ Consensus
algorithm = DLT
Slide 4
Slide 4 text
Ethereum platform
➔ Ethereum houses its own distributed virtual
machine, and scripting language called
Solidity
➔ Ethereum is a widely-used platform for
creating decentralized applications
➔ Decentralized applications are deployed on
public ledger

What’s wrong with the existing financial system?
There are an estimated 1.7 billion people who
currently lack access to financial services.
Remittance is expensive and time consuming
in the existing siloed services
Any kind of loan issuance is a costly and time
consuming process

Enterprise DLT in finance
➔ Cross border payments
➔ Trade finance
➔ Banking and lending

Decentralized Finance/ Open Finance
Decentralized Finance (DeFi) is the
movement that leverages
decentralized networks to transform
traditional financial services into
trustless and open protocols that run
without intermediaries.

More about DeFi
➔ DeFi system built from the ground up with a set of open-source protocols that are
deployed on a public blockchain like Ethereum, EOS, TRON.
➔ It has the ability to be a financial tool that is outside of government and regulatory
control
➔ It doesn’t have geographical barriers
➔ DeFi system is not completely decentralized as they still depend on some of the
external inputs.

What does it provide?
➔ Instant transaction settlement and novel secured lending
methods
➔ No credit checks, meaning broader access to people that
cannot tap into traditional services
➔ Transparency of loan issuance, collateral, repayment
➔ Standardization and interoperability (Open integration)
➔ Collateralization of digital assets
Maker protocol
MakerDAO is a decentralized organization dedicated to bringing stability to the
cryptocurrency economy
Maker protocol has 2 token system
➔ DAI - A stable coin
➔ Maker - Governance token
Slide 14
Slide 14 text
DAI economics
➔ Supply curve is shifted through a
permissionless credit factory on
Ethereum
➔ Actors are incentivized to shift the
supply curve to ensure that the price
is close as possible to $1
Slide 15
Slide 15 text
Collateralized Debt Positions
➔ Maker is a smart contract platform that stabilizes the value of Dai through a system:
Collateralized Debt Positions
➔ CDPs hold collateral assets deposited by a user and permit this user to generate Dai
➔ Active CDPs are always collateralized in excess
Slide 16
Slide 16 text
The CDP interaction
➔ Step 1: Creating the CDP and depositing collateral
➔ Step 2: Generating Dai from the collateralized CDP
➔ Step 3: Paying down the debt and Stability Fee
➔ Step 4: Withdrawing collateral and closing th
e CDP
➔ Default: CDP is automatically liquidated if the
collateral value (in USD) falls too low

Slide 18
Slide 18 text
Maker updates
Introduced Multi-Collateral Dai (Nov 18th)
➔ Collateral can be any approved asset (Not only ETH)
➔ More diversified and stable
➔ CDP is renamed to (Maker) Vault
➔ Existing DAIs are renamed to SAI

Compound Finance
(Money market)
➔ It is a protocol that establishes money
markets on Ethereum blockchain
➔ Contains pools of assets with
algorithmically derived interest rates,
based on the supply and demand
Slide 20
Slide 20 text
Supplying assets
➔ User can supply an asset to the pool of asset and
earn interest
➔ Assets supplied to a market are represented by an
ERC-20 token balance (“cToken”),
Slide 21
Slide 21 text
Borrowing assets
➔ Compound allows users to frictionlessly borrow from
the protocol, using cTokens as collateral with floating
interest
➔ Each market has a collateral factor ( borrowing
capacity), ranging from 0 to 1
➔ Liquidation is performed when borrowing outstanding
exceeds their borrowing capacity
Slide 22
Slide 22 text
Uniswap decentralized exchange (DEX)
➔ Uniswap is a completely decentralized
exchange on Ethereum blockchain
➔ A simple smart contract interface for
swapping ERC20 tokens
➔ Provides liquidity of any Ethereum asset
➔ Kyber, Oasis, 0x are other popular DEXs
Slide 23
Slide 23 text
DAOStack (Decentralized governance)
➔ Its decentralized model to organize, govern the
profit and non profit businesses.
➔ The investors can directly and collaboratively
take decisions
➔ DAOStack provides an interoperable scalable
governance platform for companies
◆ Submit project proposal
◆ Proposals are passed by community vote
◆ Records are secured and transparent
Slide 24
Slide 24 text
DeFi challenges
➔ The platforms are not user friendly for general audience (learning curve)
➔ Scalability limitations of the existing blockchain platforms
➔ No friendly regulatory compliance for the digital assets
