Introduction
Cryptocurrencies have emerged as one of the most disruptive financial innovations of the 21st century. Since the creation of Bitcoin in 2009, the cryptocurrency ecosystem has evolved significantly, with various digital currencies like Ethereum, stablecoins, and most recently Facebook's Libra entering the market. This report explores the current state of cryptocurrencies, their advantages and limitations, and the potential impact they could have on global financial systems.
What Are Cryptocurrencies?
Cryptocurrencies are digital assets that use cryptographic principles and blockchain technology to enable decentralized transactions. Key characteristics include:
- Decentralization: Transactions occur peer-to-peer without central authority
- Blockchain technology: Distributed ledger technology ensures transparency and security
- Cryptographic security: Advanced encryption protects ownership and transaction integrity
- Global accessibility: Operate across borders without traditional financial intermediaries
The cryptocurrency ecosystem has grown exponentially since Bitcoin's creation, with over 5,000 different cryptocurrencies now in existence. Major players include:
- Bitcoin (BTC): The original cryptocurrency with $180 billion market cap (as of 2019)
- Ethereum (ETH): Smart contract platform valued at $23.4 billion
- Ripple (XRP): Payment protocol cryptocurrency worth $13.7 billion
- Stablecoins: Like Tether (USDT) with $177 billion daily trading volume

Advantages and Limitations of Current Cryptocurrencies
Bitcoin: The Pioneer with Limitations
Strengths:
- True decentralization
- Secure transactions through blockchain
- Global payment network
Weaknesses:
- Limited scalability (7 transactions/second)
- High price volatility
- Energy-intensive mining process (PoW consensus)
- Slow transaction confirmation times (~60 minutes)
Ethereum: Smart Contracts Platform
Innovations:
- Introduced programmable smart contracts
- Enabled decentralized applications (dApps)
- More flexible than Bitcoin's design
Challenges:
- Still suffers from price volatility
- Scaling issues despite technological advantages
Stablecoins: Price Stability with Risks
Approach:
- Pegged to stable assets like the US dollar
- Reduces cryptocurrency volatility
Concerns:
- Centralized issuance creates counterparty risk
- Lack of transparency in reserve management
- Regulatory uncertainty
Consensus Mechanism Trade-offs
Current blockchain networks use various consensus models:
- Proof-of-Work (PoW): Secure but energy-intensive
- Proof-of-Stake (PoS): More efficient but potentially less decentralized
- Delegated Proof-of-Stake (DPoS): Fast but sacrifices some security
Each approach represents different balances between security, decentralization, and efficiency.
Libra's Potential Improvements
Facebook's proposed Libra cryptocurrency aims to address many current limitations:
Technical Innovations
- New blockchain architecture designed for high throughput
- Move programming language for safer smart contracts
- LibraBFT consensus protocol combining efficiency and security
Economic Stability
- Asset-backed design with reserve basket of stable currencies
- Global custodian network for reserve management
- Low-inflation target to maintain purchasing power
Regulatory Compliance
- Cooperation framework with global regulators
- Anti-money laundering and KYC provisions
- Transition path from permissioned to permissionless network
With Facebook's 2.38 billion users as potential adopters, Libra could achieve unprecedented scale for a cryptocurrency.
