The first half of this year witnessed a near-doubling of U.S. patent applications related to blockchain technology and cryptocurrencies compared to last year, according to CoinDesk. This surge parallels the recent meteoric rise of Bitcoin and Ethereum. While blockchain innovation continues globally, its most tangible applications remain in fintech—a sector poised to challenge financial regulators and reshape the future of digital currencies.
Blockchain's Revolutionary Potential in Finance
As previously explored, blockchain's protocol-based (rather than authority-based) framework has the potential to disrupt traditional financial systems. Beyond Bitcoin, Ethereum has emerged as a versatile contender with broader applications, demonstrating remarkable growth momentum.
Bitcoin: Record Prices and the Birth of Bitcoin Cash
Fueled by a weakening U.S. dollar, Bitcoin's price soared to $3,000 per unit** (≈NT$100,000) in mid-2017. Simultaneously, Ethereum surged from under $10** in January to nearly **$400 by June, stabilizing around $250** thereafter.
Key distinctions between Bitcoin and Ethereum:
- Bitcoin: Designed as digital gold with a fixed supply of 21 million coins, reliant on energy-intensive "mining" through cryptographic puzzles.
- Ethereum: Functions as a programmable smart contract platform, requiring its native Ether token for transactions.
In August 2017, Bitcoin underwent a contentious fork, creating Bitcoin Cash (BCC) to address scalability by doubling block size. Despite initial skepticism, BCC rapidly became the third-largest cryptocurrency by market cap.
Ethereum: Smart Contracts Drive Exponential Growth
Ethereum's smart contracts automate transactions when predefined conditions are met, leveraging blockchain's decentralized nature. This flexibility has propelled its market cap growth to 300% in six months—outpacing Bitcoin's price increases.
Comparative Market Performance (2017)
| Metric | Bitcoin | Ethereum |
|---|---|---|
| Price Growth | 300% | 3000% |
| Primary Use | Payments | Smart Contracts |
Global Regulatory Shifts
Governments are adopting nuanced stances toward cryptocurrencies:
- Japan: Recognized Bitcoin as legal tender in April 2017, enabling payments at retailers like BIC CAMERA.
- U.S. SEC: July 2017 rulings brought Initial Coin Offerings (ICOs) under regulatory oversight, treating them similarly to IPOs but with crypto-based returns.
FAQ: Understanding Crypto Developments
Q: What caused Bitcoin's fork?
A: Miner disputes over transaction speeds led to the BCC split, prioritizing larger block sizes.
Q: How do smart contracts work?
A: Self-executing code on Ethereum's blockchain automates agreements when conditions are fulfilled.
Q: Is Ethereum overtaking Bitcoin?
A: While Ethereum's utility drives adoption, Bitcoin remains the dominant store of value—for now.
