5. What is Blockchain?
• Blockchain ≠ BitCoin
• A form of distributed ledger technology
• Distributed Ledger
• Open Ledger
• Chain of Transactions
• Open and public to everyone
• Consensus - ensure all participant see the same
ledger
• Miners – Holds the ledger
• Miners need to “compete” validate the
transaction and put it into the ledger
This is a sample accounting Ledger
This is a sample distributed Ledger

6. Suitable Types of Application?
• Decentralization/Peer to Peer
• Share ”Memory”
• Programs that controls the digital assets
• Initially designed to Solve Money Transfer (Trusted)
• Ideal for Digital Asset Transfer
• Digital Smart Contract
• Replace intermediary
• Self executing financial contracts
• e-ticket, remittance, etc., only limited by your imaginations

7. Terminology
• Ethereum
• Wallet (Master Seed – Unique Address/Identify the participant)
• ERC (Ethereum Request for Comment) – similar to RFC (IETF)
• ERC20 token vs ERC223 token
• DAPP (Distributed Applications)
• Smart Contracts
• Solidity, Remix – Solidity IDE
• JavaScript Framework – React (JS)

pragma solidity ^0.4.4;
contract OddjobPayContract {
address public client;
address public tasker;
uint256 public payAmount;
constructor (address _client, address _tasker) public {
client = _client;
tasker = _tasker;
payAmount = 0;
}
}
Here is a sample Smart Contract written in Solidity
Any smart contract is concluded by two sides. Since we’re building a smart contract for a
marketplace, we’re going to have two roles:
The client, who needs to get some home service done.
The tasker, who completes a task and gets paid for it.
