2. WHY CUSTOM BLOCKCHAIN?

3. ENTERPRISE BLOCKCHAINS
REQUIREMENTS
Accountable • Keep history of transactions
Permissioned
• Only users who have permission can
access the blockchain
Mutable
• Data can be changed if participants
agree
Scalable
• Need to support more TPS compare to
public blockchains

4. TYPES OF BLOCKCHAINS
Public
Trustable and
transparent
No
intermediaries
Secured
Performance/s
calability
issues
Private
Suited for
organizational
collaboration
No anonymity
Consortium
Highly scalable
Less decentralized
No anonymity

5. TECHNOLOGY CHOICES FOR
CUSTOM BLOCKCHAIN
DEVELOPMENT
Developed
ecosystem
Absolute fin-tech
leader
Rust and Go
languages
Ethereum-
based
High-speed
Delegated POS
C++
EOS-based
Good for
permissioned
blockchains
Go language
Hyperledger
SDK for creating
blockchains
Run own validators
Rust language
Parity
Substrate
Inter-blockchain
communicator
Go language
Cosmos SDK

6. SUBSTRATE BENEFITS FOR
BLOCKCHAIN CONSTRUCTION
Fast, Efficient, Cross-platform Database/file storage
Modular P2P Networking Stack
Hot-Swappable Consensus Layer
Interportability
Configurable Transaction Queue
Flexible Runtime Library
WebAssembly for smart contracts
Forkless runtime upgrades

7. SUBSTRATE UNDER THE
HOOD
Key concepts
Nodes
Consensus
Smart Contracts

8. ARCHITECTURE

9. RUNTIME
FRAME is a library of
code that allows you to build a
Substrate runtime by
composing modules called
"pallets".

10. EXTENDING FUNCTIONALITY OF
BLOCKCHAIN
Runtime Development:
Complex applications such as:
- Decentralized Exchange
- Oracle
- Stable Coin
High entry bar for developers
Provides low level access to your
entire blockchain
Smart Contract
Simple apps, such as:
- game or voting app
- data services
Lower bar for developers
Safer
Potentially less performance

11. EVM PALLET
Substrate Runtime
Ethereum Smart Contract
EVM Pallet

12. FRONT-END

13. DAPP DEVELOPMENT JOURNEY
Deploy
Substrate Chain
Add custom
pallet
Modify front-
end template to
add a custom UI
