1. Highlights from 2024: Key Milestones in Crypto Technology
Ethereum’s Dencun Upgrade:
In 2024, Ethereum underwent its most significant network upgrade to date with the Cancun-Deneb (Dencun) update. This milestone introduced proto-danksharding, a feature aimed at lowering costs for Layer-2 rollups by simplifying data availability and boosting transaction efficiency. While the changes were a topic of robust discussion, they marked a critical step toward Ethereum’s long-term goals of scalability and efficiency, solidifying its position as the leading smart contract platform.
Solana’s DeFi Growth:
Solana achieved a major milestone, reaching $9 billion in total value locked (TVL) within its decentralized finance (DeFi) ecosystem — the highest in three years. This growth was driven by an influx of institutional interest and strategic integrations, with companies like Franklin Templeton and Société Générale leveraging Solana for tokenized asset initiatives. Solana’s reach also expanded with platforms like Robinhood adding SOL for trading and ETF filings linked to Solana by Cboe Global Markets.
Quantum Computing Concerns:
Google’s breakthrough in quantum computing, particularly its innovative quantum chip, sent ripples of concern through the crypto industry regarding blockchain security. The chip’s capabilities reignited discussions about the vulnerabilities of traditional encryption methods. Experts stressed the urgency of adopting quantum-resistant encryption to safeguard digital assets, as advancements in quantum technology could pose a potential risk to blockchain networks in the future.
Layer-2 Solutions Thriving:
Layer-2 solutions experienced a surge in adoption as projects like Arbitrum, Optimism, and Base addressed Ethereum’s scalability issues. Arbitrum recorded over a billion transactions, while Optimism expanded its ecosystem with OP Stack technology, fostering collaboration through its Superchain initiative. Base, Coinbase’s Layer-2 network, leveraged its parent company’s user base, attracting significant attention, including the launch of tokenized treasury funds by Franklin Templeton.
DeFi Innovations:
Prominent DeFi platforms made waves in 2024. Grayscale Investments introduced a fund centered on Aave, while Uniswap Labs unveiled plans for Unichain, a decentralized Layer-2 blockchain. MakerDAO rebranded as Sky, introducing new governance tokens (SKY), stablecoins (USDS), and innovative tokenomics under its Endgame Plan. These developments highlighted the sector’s ongoing evolution.
2. Upcoming Trends for 2025
