Week 7 Flashcards
What two keys make up Public-Key Cryptography
public (shared) & private (secret).
benefit of Public-Key Cryptography
Ensures secure transactions and non-repudiation.
what are Cryptocurrencies
Digital tokens using cryptography, decentralized peer-to-peer architecture.
what do Operational risks in cryptocurrencies refer to
potential losses from failed internal processes, people, systems, or external events.
what is used to Verify signatory identity using publicly available data.
Digital Signatures
what does Decentralized mean
No central control or monetary policy; rules are public.
what is the Transaction Process of bitcoin
Transactions are broadcast to the network and verified by nodes.
what is Blockchain
A shared public ledger containing a record of
all Bitcoin transactions
what is Mining
New coins created by solving cryptographic puzzles. Bitcoin capped at 21M coins
where are verified bitcoin transactions added to
blockchain, a public ledger.
what is Blockchain formed from
mined blocks, which verify transactions or mine new coins
true or false, The history of every coin can be tracked from
the day it was created.
true
how is The blockchain updated
periodically updated with new transaction blocks
crypto vulnerabilities
- Decentralized
P2p verification - irreversible transactions
- anonymity
-sensitive info
-price/value instability
-international regulatory risk
exposures of crypto
- multiplicity of jurisdictions and micropayments
- reliance on hardware and software
why is Decentralized Governance: a risk
- Lack of central authority.
- Risk of coordinated attacks.
- Majority control of CPU power is essential for network security.
- Risk of protocol changes
why is Peer-to-Peer Verification a risk
- Potential for double-spending attacks.
- Vulnerability to selfish mining strategies
why is Transaction Irreversibility seen as a risk
- Losses due to irreversible transactions in case of errors or fraud.
- IT disruptions can lead to irreversible losses
why is Anonymity seen as a risk
- Challenges in tracking and accountability
why is Multiplicity of Jurisdictions seen as an exposure
Legal and regulatory complexities.
why is multitiplicity of Micropayments seen as an exposure
High volume of small transactions increasing system strain.
Why is Hardware and Software Reliance seen as an exposure
- Risks associated with system failures and cyberattacks
4 key operational risk exposures

Privacy challenges of bitcoin
- Bitcoin users can create a new address per transaction for privacy.
- Balances privacy vs. regulatory oversight.
