## A Brief Overview of 2021
To gain insight into the future trajectory of the blockchain landscape, it is crucial to reflect on the significant milestones and happenings that characterized this pivotal year.
### **The Surge of Record Highs in Cryptocurrency**
The year 2021 launched with an extraordinary price increase for Bitcoin (BTC). The prominent cryptocurrency eclipsed its previous all-time high of $20,000 from 2017, reigniting investor optimism. Within a mere four months, Bitcoin soared to an astounding price of $60,000, representing a threefold increase from its prior ATH.
This upward trend extended beyond Bitcoin. Ethereum (ETH), the second-largest cryptocurrency by market value, also experienced significant gains despite navigating challenges posed by elevated transaction costs amid the booming decentralized finance (DeFi) sector. By April, subsequent to network protocol enhancements, Ethereum reached a new peak of $4,400.
In the midst of this optimism, the total cryptocurrency market capitalization ballooned to $2.5 trillion from $700 billion at the year’s outset, showcasing an astonishing 257% increase. Investors enjoyed considerable returns, marking 2021 as an exceptional year for digital assets.

### **The May 2021 Market Decline**
Nevertheless, this remarkable ascent was paired with an equally severe downturn. In May 2021, the market faced considerable volatility:
1. **FUD from Tesla**: A significant disruption to investor morale occurred when Tesla, once a strong supporter of Bitcoin, declared it would no longer accept the cryptocurrency for vehicle purchases due to environmental issues.
2. **China’s Restrictions**: Further adding to the rising uncertainty was China’s announcement of a complete ban on cryptocurrency mining and trading. This resulted in a massive exodus of miners from the nation, enhancing market volatility.
3. **Market Correction**: Bitcoin’s price fell to $30,000—a dip of 50%—while Ethereum dropped below $1,800, losing 60% of its value from its ATH. The overall market turned bearish as a wave of panic-selling transpired.

## What Lies Ahead? Upcoming Blockchain Enhancements and Future Projections
The market recovery has been gradual yet encouraging, with many investors keenly anticipating upcoming technological innovations to major blockchain platforms. These advancements might reignite bullish activity.
### **1. Ethereum’s London Hard Fork and Transition to PoS**
Ethereum experienced the **London Hard Fork** on August 4, 2021. This upgrade featured modifications to transaction fee structures and introduced an EIP-1559 mechanism that burns a portion of transaction fees. This initiative has effectively transformed ETH into a deflationary asset, enhancing its attractiveness as a store of value.
However, the most significant development for Ethereum is on the horizon—its complete transition to a **Proof-of-Stake (PoS)** consensus model, expected to launch alongside Ethereum 2.0. PoS is anticipated to:
– Reduce energy consumption by 99%.
– Significantly lower transaction fees.
– Enhance the scalability of the Ethereum blockchain.
This advancement could dramatically enrich user experiences for projects dependent on Ethereum, from DeFi platforms to NFT marketplaces. Ethereum’s shift to PoS is poised to be a landmark event, not only for the blockchain itself but for the wider crypto ecosystem.

### **2. Bitcoin’s Taproot Upgrade**
Bitcoin is anticipated to implement the **Taproot Upgrade** by the close of 2021. This will introduce **Schnorr signatures**, which enhance transaction privacy and efficiency. The update will equally make intricate multi-signature transactions indistinguishable from regular ones, reinforcing user privacy.
The Taproot update signifies Bitcoin’s first major protocol improvement since the 2017 Segregated Witness (SegWit), underscoring the necessity for continual innovation for the original cryptocurrency.

### **3. Cardano’s Integration of Smart Contracts**
Cardano (ADA), a notable proof-of-stake blockchain, has been long regarded for its potential to compete with Ethereum. By late 2021 or early 2022, Cardano is projected to acquire **smart contract capability**, allowing decentralized applications (dApps) and DeFi protocols to function on its network.
This pivotal advancement will position Cardano as a formidable player in the blockchain arena, encouraging innovation and drawing developers and users to its ecosystem.
