เทคโนโลยีตัวนี้”
“อย่ำงที่ผมบอก ข้อมูลมันถำวร ตั้งแต่อำยุของรถคันนี้เริ่มขึ้นจนรถพัง ข้อมูลจะอยู่กับรถคัน
นี้ตลอดว่ำใครใช้เมื่อไหร่อย่ำงไรบ้ำง อีกทั้งมันปรับแก้ไม่ได้ทำให้มันมีควำมน่ำเชื่อถือ ไม่

4. “Blockchain is to Bitcoin, what the internet is to email.
A big electronic system, on top of which you can build
applications. Currency is just one,”
Sally Davies
Technology reporter @ Financial Times

5. “We will never hear about people's Bitcoin accounts being
frozen or seized by a government agency.”
Roger Ver
Early Bitcoin Investor,
owner of bitcoin.com

6. “People ask me, ‘Are you going to sell your bitcoin [for fiat]?’
and I say, ‘Why would I sell the future for the past?’”
“I don’t know why anyone would want to go back to fiat when crypto is distributed,
secure and global, while fiat is subject to the whims of political forces”
Tim Draper
American venture capital investor
@600$ 30,000 2014 pd 10,000$ 2017 pd 250K 2022,

7. Vitalik Buterin
Founder of Ethereum
“In order to have a decentralised database, you need to have
security. In order to have security, you need to have incentives.”

8. Virtual currencies - This is not about digital payments
in existing currencies (Paypal, Alipay, etc..)
• Too volatile at the moment, so no risk to current fiat / bank
• Good for countries with weak institutions and unstable
national currencies
• Maybe one day easier and safer than obtaining paper bills
• No settlement risk
• No clearing delays
• No central registration
• No intermediary to check account and identities
Christine Lagarde
MD@ International Monetary Fund

ลำยเซ็นต์ดิจิตัลของ Vendor, Custodian, และ Auditor
2# ส่วนที่สองคือกำรพิมพ์ (Mint) DGX Token ออกมำ
โดยในกระบวนกำรนี้ผู้ค้ำจะส่ง Asset Card ไปที่ Minter
ซึ่งจะรับ Asset Card ไว้และออก Gold Token ส่งคืนให้ผู้ค้ำ
โดย 1 Gold Token เป็นตัวแทนทองคำ 1 กรัม

72. So which app is good with Blockchain?

73. • Similar thing can be implemented on (traditional)
centralized technology (Client-server Application)
• There is at least trustful party which can provide
the centralized platform
• No party can fully trust each other
• Security and Immutability
• Perfect transparency
• Replacement of old tech that require open
standard.
Blockchain overkill if… What does Blockchain fit?
Blockchain Application Summary

74. Blockchain for
Money Remittance?

75. Traditional Money Remittance
1. Alex goes to his local hawala agent and gives him
some cash and a password, which he and Beth
share.
2. The agent telephones Beth's local agent and tells him
to release funds to someone who can provide the
password.
3. Beth walks in to her agent, says the password, and
receives cash. Commissions can be taken from either
or both agents.
• Alex has to trust that his agent will do the right thing, as
he is handing over cash.
• Beth has to trust that her agent will do the right thing, as
she is expecting to receive cash.
• The agents need to trust each other over the repayment
of the debt (IOUs).

76. Look at Ripple

77. OmiseGo
• Real Time Transaction
• P2P Finance Transaction
• Cross currencies/assets
• Cross national borders
• Cross corporate ledger
=

78. OmiseGo – Road Map
This is the most
important component in
my opinion

79. Why OmiseGo’s Vision is so important?
Unbanked the banked
• It will disrupt the current payment landscapes
• Enable user to trade any value (currencies, store
loyalty, points, rewards, in-game point) efficiently and
at low cost across internet
“Cross-platform transactions means
grocery points could one day be
exchanged for air miles.”
