The DeFi (Decentralized Finance) realm is undergoing a rapid transformation fuelled by the advent of Layer 1 blockchains. These advanced platforms are reshaping the DeFi landscape, making it more accessible, efficient, and expansive. In the epicenter of this revolution is a technology known as smart contracts.

This article delves into the role of Layer 1 blockchains in broadening the DeFi ecosystem, focusing on the pivotal role of smart contracts in driving this expansion. To gain a deeper understanding of this topic, we’ll explore top Layer 1 blockchains like Solana, Algorand, Binance Chain, and Avalanche, among others.

Exploring the Basics: Layer 1 and Layer 2 Blockchains

Before diving into the specifics, it’s essential to understand the basics. All crypto tokens can be broadly classified into two categories: Layer 1 and Layer 2. Layer 1 tokens possess their unique blockchains, while Layer 2 tokens are constructed atop Layer 1 blockchains, typically through smart contract technology.

Layer 2 tokens can be new tokens or more intricate projects known as Decentralized Applications

. There are also Layer 2 projects that do not use smart contracts, such as Bitcoin’s Lightning Network, designed to quicken and cheapen Bitcoin payments via transaction batching.

Understanding Smart Contracts

Smart contracts are self-executing contracts where the terms of agreement are directly written into lines of code. These contracts allow for trusted transactions to take place without the need for a central authority, legal system, or external enforcement mechanism. They are a fundamental part of the blockchain technology, residing at the heart of Layer 1 and Layer 2 blockchains.

Smart contracts have become instrumental in the development of DeFi applications and the broader web3 ecosystem. They have enabled the creation of decentralized applications that can work autonomously, interact with users, and manage digital assets according to predefined rules.

Layer 1 Blockchains: Addressing the Scalability Issue

Different Layer 1 blockchains are designed and optimized for different objectives. Bitcoin, for instance, is designed to be a digital currency for uncomplicated, trustless transactions with enforced scarcity to maintain its value. On the other hand, Ethereum was the pioneer blockchain to incorporate smart contracts, hosting the initial wave of dApps and tokens that signaled the advent of DeFi and web3.

One of the main challenges with Ethereum, the most prominent blockchain for Layer 2 project development, is its Proof of Work (PoW) mining system and high gas fees. These have proven to be roadblocks to transaction speed and scalability within its DeFi ecosystem. As a result, many of the smart contract-enabled Layer 1 blockchains developed since were created to address these challenges.

Solana: A Scalable Layer 1 Blockchain

Solana and Algorand, for instance, leverage a Proof of History (PoH) and Proof of Stake (PoS) consensus mechanism respectively. These mechanisms facilitate lower fees and quicker transaction times. Solana, in particular, was developed to address Ethereum’s scalability problems.

With a unique consensus mechanism that combines PoS with PoH, Solana can facilitate faster block validation and therefore quicker transaction time. Solana’s PoH mechanism allows timestamping to be integrated into the blockchain itself, which enables faster block validation and hence, faster transaction time.

Algorand: Facilitating High-frequency Transactions

Algorand, on the other hand, aims to support high-frequency, payment-sized transactions. Currently, Algorand facilitates an estimated 1,000 transactions per second with a final confirmation time of five seconds on the blockchain.

Algorand’s unique, two-tiered blockchain structure allows it to process transactions efficiently. The base layer supports basic transactions as well as smart contracts for new tokens and atomic swaps. The second layer is reserved for more complex smart contracts, such as those powering dApps.

Binance Chain: Leveraging a Global User Base

Binance Chain, formerly known as Binance Smart Chain, is a blockchain launched by cryptocurrency exchange Binance. It has seen significant growth in recent years, majorly due to its ability to support new tokens and dApps without Ethereum’s high fees.

Binance Chain, with its extensive global user base, can draw on the massive customer base of Binance, the largest cryptocurrency exchange in the world. This has made Binance Chain incredibly attractive for developers looking to build dApps and DeFi protocols.

Avalanche: The Interoperable Layer 1 Blockchain

Avalanche is another Layer 1 blockchain designed for interoperability. Avalanche is compatible with the Ethereum Virtual Machine (EVM), meaning that dApps and tokens built on the Ethereum blockchain can be migrated to the Avalanche blockchain with minimal extra effort from developers.

Apart from interoperability, Avalanche also focuses on scalability and customizability, making it an ideal platform for versatile dApp development. Avalanche’s three-blockchain set serves different use cases, each contributing to its robustness and appeal.

Expanding the DeFi Ecosystem with Layer 1 Blockchains

The emergence of new Layer 1 blockchains is broadening the DeFi ecosystem. These blockchains are addressing the scalability, speed, and fee issues prevalent in Ethereum, thus attracting more developers to build dApps and DeFi protocols on their platforms.

The role of smart contracts in this expansion cannot be overstated. Smart contracts facilitate the creation of autonomous applications that can interact with users and manage digital assets according to predefined rules. Today, if you’re looking to hire a smart contract development company, the choice is no longer limited to Ethereum.

The Future of Layer 1 Blockchains

While many Layer 1 blockchains are showing promise in their ability to challenge Ethereum’s dominance, they still have a long way to go. Ethereum continues to lead in transaction volume, particularly in popular web3 areas like NFTs. However, its high fees and scalability issues are driving developers and users to explore other Layer 1 blockchains.

The growth of these Layer 1 blockchains and their contribution to the DeFi ecosystem is testament to the potential of blockchain technology and smart contracts. Whether you’re a developer looking to delve into smart contract development or a business looking to hire a smart contract development company, today’s Layer 1 blockchains offer a plethora of opportunities to explore and exploit.
