management, law (smart contracts), regulation

• Permission = Private blockchains where people tend to know and trust each other

• Permissionless = Non-restrictive on users and people may not know or trust each other

Hashing 1

• Hashing converts text to a 64 string of numbers and letters

• Cannot be reversed

• Hashing is an important part of blockchain security systems

• Blockchain records are made tamper proof with a hash where one of the inputs is the hash of the immediately preceding block

Hashing 2

Hashing “Risk Management and Financial Institutions” (without quotation marks) using SHA gives:

1dcc48387a27cd95378b08ab26261b161a97c51a7c9146f3d3f f73710d656a3f

Adding the edition number so that ``Risk Management and Financial Institutions 5'' is input (again without quotation marks) produces a totally different hash:

117e1e23121f8db4b75d3e2a63d37ef052b11a63cf448721825 aadb882492c6b

Regulation

• Regulation is a barrier to entry for FinTechs

• Regulators do not want to stifle innovation and have come up with some plans that provide some regulatory relief for innovators

• But regulating FinTechs is a challenge (e.g., HFTs have caused problems for regulators)

• Can a computer program be regulated in the same way as the systems in a large bank?

Risk Management and Financial Institutions 5e, Chapter 28, Copyright © John C. Hull 2018

RegTech

• RegTech is the word used to describe the use of technology to improve compliance with regulations. Examples: • Screen customers and transactions in real time for

money laundering, terrorist financing, and sanctions
