The Evolution of Blockchain Technology to watch in 2024

1. Layer 2 scaling solutions: Addressing Blockchain’s scalability challenge

One of the most persistent challenges blockchain has faced since its inception is scalability—the ability to process large volumes of transactions quickly and affordably. In 2024, layer 2 (L2) scaling solutions have taken center stage, providing innovative ways to tackle this issue. These solutions, built on top of existing blockchain networks, aim to increase transaction throughput without compromising security.

Among the most notable L2 technologies this year are zero-knowledge rollups (ZK-rollups). These bundle multiple transactions into a single batch, which is then processed off-chain, significantly reducing the load on the main blockchain network. Ethereum, one of the largest and most widely used blockchains, has benefited enormously from this technology. Solutions like ZkSync and StarkNet have enabled Ethereum to handle thousands of transactions per second (TPS), compared to its previous limit of 15 TPS on the base layer. This advancement makes Ethereum faster, more efficient, and more accessible for decentralized applications (dApps) and smart contracts.

Another key L2 solution is Polygon and its zkEVM (zero-knowledge Ethereum Virtual Machine). By allowing developers to deploy Ethereum smart contracts directly onto Polygon’s L2 network, zkEVM has drastically reduced transaction costs. In 2024, transaction costs on Polygon’s zkEVM are as low as $0.01, compared to the soaring gas fees of several dollars on the Ethereum base layer during high-demand periods. These improvements are making blockchain more practical for everyday use and are driving its adoption across various sectors.

The evolution of the Bitcoin Lightning Network is also a major highlight this year. In 2024, the network’s liquidity exceeded 5,000 BTC, a 25% increase from 2023. This demonstrates that L2 scaling solutions are just as critical for Bitcoin as they are for Ethereum, paving the way for faster, cheaper, and more scalable payment systems that bring blockchain technology closer to mainstream use.

2. New and emerging Crypto Coins: Innovations beyond Bitcoin and Ethereum

While Bitcoin and Ethereum remain the dominant forces in the blockchain world, 2024 has seen the rise of new crypto coins and ecosystems that are pushing the boundaries of innovation. These emerging blockchain platforms bring unique architectures and consensus mechanisms, contributing to the ever-expanding landscape of decentralized technologies.

Coins such as Aptos and Sui have gained traction by offering alternative consensus algorithms and novel features. However, the proliferation of multiple blockchains has brought the issue of cross-chain interoperability to the forefront. As the blockchain ecosystem becomes more fragmented, the need for seamless transfer of assets and data across different networks becomes critical.

One of the most promising solutions in this space is LayerZero, an omnichain bridging protocol. In 2024, LayerZero has powered billions of dollars in cross-chain transactions by enabling developers to build dApps that can communicate across multiple blockchains. This year alone, LayerZero has formed over 100 partnerships, solidifying its position as a key player in blockchain interoperability.

Another important player is the Cosmos Network, which leads with its Inter-Blockchain Communication (IBC) protocol. This technology allows different blockchains to transfer assets and information, making cross-chain transactions more efficient. As of 2024, over 50 blockchains actively use the IBC protocol, representing a 30% increase from 2023. This growth showcases the expanding role of interoperability in the blockchain ecosystem.
