As someone who has been deeply immersed in the world of cryptocurrencies for quite some time now, I can confidently say that layer-1 blockchains are indeed the backbone of this rapidly evolving digital economy. They provide a solid foundation upon which countless decentralized applications, peer-to-peer transactions, and smart contracts are built.
Cryptocurrencies are built on blockchain networks. Much like a house is built starting with a solid foundation, a crypto network begins with its layer-1 blockchain. This is the bedrock of the entire system, handling processes like security, transaction processing, and much more.
In this article, we’ll delve into the specifics of layer-1 within the context of cryptocurrency and blockchain technology. We’ll define what a Layer 1 blockchain is, explore its applications in the real world, and provide relevant examples to help you understand its significance.

What is blockchain?
A blockchain network is essentially a collection of interconnected computers known as nodes, where these nodes cooperate to handle data in segments called blocks. Each block gets appended to an unalterable record called the ledger, and only when the majority of these nodes concur can modifications be made to this record.
In essence, having numerous nodes within a blockchain system significantly enhances its security and makes it resistant to censorship or attacks. The inherent traits of being unalterable and permanent in terms of data make it suitable for establishing secure cryptocurrency systems such as Bitcoin.
What is layer-1 blockchain?
In the world of cryptocurrencies, a layer-1 blockchain represents a decentralized network that facilitates both execution and confirmation of transactions directly on the digital ledger itself.
A layer-1 blockchain serves as the primary network essential for a cryptocurrency to operate, while layer-2 blockchains are auxiliary networks designed to alleviate strain from layer-1 networks.
For instance, Bitcoin and Ethereum operate independently on their own first-layer blockchains, meaning they don’t rely on any additional blockchain networks to perform essential functions like verifying transactions and producing or issuing new units of digital currency.
Decentralization in L1 blockchains
In the world of cryptocurrencies, layer-1 blockchains are typically structured in a way that promotes decentralization, which signifies that no single entity holds dominion over the nodes responsible for executing transactions and maintaining the network’s operations.
Mining entities handle transactions to receive cryptocurrency compensation, with the operation of smaller blockchain networks (L1 chains) sometimes being centralized, whereas systems such as Bitcoin and Ethereum are governed by rival mining pools, preventing any single individual from having ultimate control over decision-making processes.
The significant shift towards decentralization is a key reason for the widespread appeal of layer-1 blockchains as well as the overall appeal of cryptocurrencies.
The autonomy they possess enables them to design and adapt their unique security frameworks and administrative structures, enhancing their dependability compared to various other blockchain tiers such as Layer-2, Layer-3, etc. However, what specific aspects contribute to the trustworthiness and robustness of layer-1 blockchains? Let’s explore that below.
Key characteristics of layer-1 blockchain
1st-tier blockchains embody multiple functionalities, all geared towards strengthening the overall performance and self-governance of the blockchain network. Here are some key attributes:
1. Freedom
In simpler terms, choosing a layer-1 blockchain for a new cryptocurrency project means they can easily market it because they have full control over their governance and security. By designing their own protocols at this base layer, they don’t need to depend on other layers, thus ensuring stronger security and decentralization.
2. Native cryptocurrency
In layer-1 protocols, users carry out tasks like staking, governance, and transaction fees exclusively with the native digital currency. This setup fosters transparency and trust, thereby contributing to the expansion of the layer-1 blockchain network.
3. Consensus mechanisms
Using a unique consensus mechanism tailored for each layer-1 blockchain, network integrity is maintained and transactions are thoroughly verified with robust security measures. Two well-known instances of these mechanisms include Bitcoin, which relies on Proof-of-Work (PoW), and Ethereum, which operates using Proof of Stake (PoS). As the nodes follow this consensus algorithm, the entire transaction process becomes both transparent and secure.
4. Community-driven governance
Participants significantly influence the expansion of layer-1 blockchain ecosystems, as they participate in decision-making procedures that shape the future of these projects directly. This involvement fosters a feeling of ownership and strengthens decentralization, which is essential for inspiring fresh cryptocurrency initiatives to emerge within this domain.
As a crypto enthusiast, I appreciate the versatility, the ability to execute smart contracts, and the continuous growth possibilities that come with this investment.
List of layer-1 blockchains
Among over a hundred layer-1 blockchain platforms that prioritize security, self-governance, and essential characteristics, this analysis will focus on the leading trio of these layer-1 blockchains.
1. Bitcoin (BTC)
Bitcoin (BTC), introduced anonymously by Satoshi Nakamoto in 2009, is the pioneer among cryptocurrencies. It functions based on the Proof-Of-Work system. As a fundamental protocol, Bitcoin offers self-governing properties through strong security measures, facilitating direct transactions between individuals without requiring intermediaries. This autonomy and high level of trust makes it one of the most reliable blockchain networks and digital currencies in the web3 universe.
2. Ethereum (ETH)
Ethereum pioneered smart contracts in the blockchain realm, paving the way for a surge of development within this sector. This innovation made it simpler for web3 developers to construct decentralized applications (dApps) on the Ethereum blockchain. Additionally, Ethereum introduced the Proof-of-Stake (PoS) system, improving scalability and significantly reducing energy consumption in comparison to previous models.
3. Binance Smart Chain (BSC)
Binance Smart Chain offers two significant benefits: keeping transaction fees minimal and ensuring optimal performance consistently. As a layer-1 blockchain, it has garnered attention in the Decentralized Finance (DeFi) sphere thanks to its intuitive operating system and swift transaction processing speeds. This makes it an attractive choice for both individual users and new development projects aiming to establish themselves on this blockchain platform.
The future of layer-1 blockchains
Without a shadow of a doubt, it’s clear that base-level blockchains are indispensable in the realm of decentralized technology. They serve as the backbone for running independent applications, executing transactions on self-contained blockchain systems, and supporting smart contracts. In essence, they form the fundamental layer within the blockchain ecosystem. However, it’s important to acknowledge that these networks encounter issues, particularly when transaction volumes or user adoption significantly increase over time.
In response to these hurdles, numerous layer-1 blockchains are exploring and studying ways to enhance their structural frameworks and consensus mechanisms.
While some blockchains have implemented Proof-of-Stake (POS) and sharding to decrease transaction fees and latency, these changes haven’t entirely addressed the issues for layer-1 blockchains like Bitcoin and Ethereum. As a result, they are exploring layer-2 blockchain solutions, which offer more extensive options for tackling the challenges faced in the blockchain sector.
Looking ahead, we might witness further advancements in base-level protocols, as they adjust to different environments, enhance interoperability, and essentially integrate essential upgrades through the collaborative efforts of layer-2 and layer-3 blockchain technologies.
