CHAPTER 7: INTRO TO DIGITAL ASSETS Flashcards
Digital Assets
- New investment class; created, stored, and transmitted electronically with ownership/use rights.
Distributed Ledger:
- Shared database across network nodes.
- Infinite nodes possible; each has a copy.
- Consensus mechanism ensures synchronization.
- Immutable records; once created, cannot be changed.
Distributed Ledger Technology (DLT) and Cryptography:
- Uses cryptography for data security through encryption.
Smart Contracts:
- Self-executing programs based on pre-set conditions.
- Example: Auto transfer of collateral on default.
DLT Networks:
- Peer-to-peer financial asset creation, exchange, and tracking.
- No central authority for transaction validation.
DLT Benefits:
- Accurate, transparent, and secure record-keeping.
- Faster ownership transfer.
- Facilitates peer-to-peer interaction
DLT Drawback:
- High energy consumption for transaction verification.
Blockchain Characteristics:
- Information recorded in sequential blocks.
- Blocks are chained and secured with cryptography.
- Each block groups transactions and links to the previous block.
Adding Transactions to Blockchain:
- Transaction occurs between buyer and seller.
- Transaction is broadcast to network nodes.
- Nodes validate transaction details and parties.
- Verified transaction forms a new block with others.
- New block is cryptographically linked to previous blocks.
- Transaction completes, updating the ledger.
BITCOIN: Permissionless or Permissioned?
Permissionless
ETH also permissionless
RIPLE: XRP: Permissioned
Consensus Protocols:
- Set of rules for verifying and chaining blockchain transactions.
- Two main types: Proof of Work (PoW) and Proof of Stake (PoS).
Proof of Stake (PoS):
- Validators pledge capital to vouch for block validity.
- Validators propose blocks and must be attested by majority.
- Security based on stakeholders controlling computational power.
DLT Networks:
- Can be permissionless or permissioned.
Proof of Work (PoW):
- Uses computational lottery to add blocks.
- Miners solve cryptographic problems to verify transactions.
- Requires powerful computers and large energy consumption.
- High computational power makes manipulation difficult.
BTC: PROOF OF WORK
ETH: PROOF OF STAKE
BTC: You bring computing power
ETH: You bring money (stakes)
Permissionless Networks:
- Open to any user.
- Transactions are immutable.
- All users see all transactions.
- No central authority.
- Example: Bitcoin.
Permissioned Networks:
- Restricted participation.
- Controlled access levels.
- Different permissions for users.
- Example: Users enter transactions, regulators view history
PERMISSIONED VS PERMISSIONLESS
Speed:
- Permissioned: Faster, limited validators.
- Permissionless: Slower, many validators.
Cost:
- Permissioned: Cost-effective, few validators.
- Permissionless: Costly, many validators.
Decentralization:
- Permissioned: Partially decentralized.
- Permissionless: Fully decentralized.
Access:
- Permissioned: Limited membership.
- Permissionless: Unlimited membership.
Governance:
- Permissioned: Centralized organization.
- Permissionless: Decentralized, member-maintained.
Digital Assets & Types
- Electronic records with rights to use, buy, or sell.
Types of Digital Assets:
- Bitcoin
- Cryptocurrencies: Altcoins, Stablecoins, Central Bank Digital Currencies, Memecoins
- Non-Fungible Tokens
- Tokens: Security Tokens, Utility Tokens, Governance Tokens
Cryptocurrencies:
- Digital or electronic currency without physical form.
- Enable transactions between buyers and sellers.
- Issued by private entities.
- Usually lack central authority, except CBDCs.
Cryptocurrency Supply Limits:
- Many have self-imposed issuance limits.
- Example: Bitcoin’s limit of 21 million.
- Limited supply may maintain value, but lack fundamentals causes volatility.
Initial Coin Offering (ICO):
- Unregulated process for selling crypto-tokens to investors.
- Investors fund the company, tokens used later for products/services.
Central Bank Digital Currencies (CBDCs):
- Digital versions of central bank currencies.
- Tokenized fiat currency, like digital bank notes or coins.
Which of the following is not a benefit of DLT?
A Streamlining of current post-trade processes.
B Energy efficient verification of transaction activity.
C Faster transfer of ownership.
B is correct. A drawback of DLT is that the computational processes underlying DLT require massive amounts of energy to verify transaction activity.
A cryptocurrency miner can receive new digital assets by:
A solving complex algorithm puzzles to validate blocks of transactions onto a blockchain network based on a PoW protocol.
B staking his own cryptocurrencies to validate and attest to the new blocks of transactions onto a blockchain network based on a PoS protocol.
C Both A) and B)
C is correct. The validation of the transactions, or “mining,” always comes with rewards under both PoW and PoS consensus protocols. A successful miner that validates the transactions obtains new digital assets, either a cryptocurrency or a token.
Compared to permissioned blockchain, permissionless network is characterized by:
A cost effectiveness.
B slower speed.
C limited membership.
B is correct. Permissionless network is slower as several members have to reach consensus, which decreases network speed and scalability.
A is not correct because permissionless is not cost-effective as many members are required to validate each transaction.
C is not correct because membership is unlimited, based on the decentralized nature of permissionless blockchain.
