What Is Layer 0 in Blockchain?

Talking about Layer 0 in blockchain brings us to a generation of blockchain networks that aim to optimize the underlying network infrastructure as well as improve the scalability, security, and performance of blockchain applications. These blockchains are designed to operate at the lowest level of the networking stack, which includes the hardware, network protocols, and operating systems that support the blockchain network.

Basically, Layer 0 is the foundational framework that underlies all blockchain protocols. It provides the underlying infrastructure necessary for Layer 1 blockchains to operate and communicate with each other effectively. This infrastructure enables users to build decentralized applications and businesses, validate data sources, and more. In other words, Layer 0 is the essential building block upon which the entire blockchain ecosystem is built.

The main goal of Layer 0 blockchains is to address some of the key challenges facing traditional blockchain networks, such as low transaction throughput, high transaction fees, and slow transaction processing times. These challenges have limited the adoption of blockchain technology in mainstream applications, and Layer 0 blockchains aim to provide a solution to these problems.

Layer 0 blockchains use innovative approaches to network infrastructure, such as sharding, parallel processing, and consensus algorithms that optimize for scalability, speed, and security.

Layers in Blockchain

The blockchain ecosystem is categorized by multiple layers that work together to create a secure and decentralized network. These layers are sometimes referred to as “blockchain stacks” or “protocol stacks.” They include Layer 0, Layer 1, Layer 2, and Layer 3.

Layer 0: Layer 0 defines a blockchain architecture that is designed to operate at the network infrastructure layer. In other words, Layer 0 blockchains are built to optimize the underlying technology and protocols that enable the blockchain network to operate. They provide the essential infrastructure that enables the creation of Layer 1 blockchains. Serving as the foundation of blockchain networks and applications, Layer 0 protocols are one of several solutions that aim to address some of the key challenges facing the industry, including scalability and interoperability. Examples of layer 0 blockchains include Avalanche (AVAX), Cosmos (ATOM), Polkadot (DOT), and Venom.

Layer 1: This is the core layer of the blockchain, also known as the “base layer.” It includes the underlying technology and protocols that support the blockchain network, such as the consensus algorithm, cryptographic protocols, and data structures. Examples of Layer 1 blockchains include Bitcoin (BTC), Ethereum (ETH), and Litecoin (LTC).

Layer 2: This layer is built on top of Layer 1 and includes protocols and technologies that enhance the scalability, speed, and functionality of the blockchain network. Examples of Layer 2 solutions include payment channels, sidechains, and off-chain protocols. Layer 2 solutions are designed to reduce congestion on the blockchain network and increase transaction throughput.

Layer 3: This layer is the application layer, also known as the “dApps layer.” It includes decentralized applications and smart contracts that are built on top of the blockchain network. Examples of Layer 3 applications include decentralized finance (DeFi) platforms, non-fungible token (NFT) marketplaces, and identity verification systems. Layer 3 applications leverage the security and decentralization provided by the underlying blockchain infrastructure to provide new and innovative services.

How Does Layer 0 Protocol Work?

Layer 0 protocols serve as the foundation of the blockchain network upon which Layer 1 blockchains can be built. They provide the essential infrastructure necessary to create a secure, decentralized, and interoperable blockchain ecosystem.

One of the key features of Layer 0 protocols is their ability to provide consensus mechanisms that enable network participants to agree on the state of the blockchain. Consensus mechanisms are essential for ensuring the security and validity of the blockchain network. Layer 0 protocols typically implement their own consensus mechanism, which can vary depending on the specific protocol.

Layer 0 protocols are also designed to address some of the scalability challenges facing the blockchain industry. By using innovative approaches to transaction processing and data storage, Layer 0 protocols can increase the speed and efficiency of blockchain networks, allowing for faster transaction processing and improved network scalability.

Key Elements of Layer 0

Layer 0 blockchains are made up of three primary elements: main chain, sidechains, and cross-chain transfer protocol.

1. Main chain. Also known as the relay chain, this component serves as the primary blockchain where transaction data from Layer 1 networks are backed up and processed.
2. Sidechains. These are independent Layer 1 blockchains that run in parallel to the main chain. As sovereign networks, they have their own tokens, consensus mechanisms, and blockchain protocols. They may or may not rely on the main chain for security.
3. Cross-chain transfer protocol. This component consists of blockchain protocols that enable the secure exchange of information between two or more independent blockchain networks. These protocols facilitate interoperability between different blockchain networks and allow for the transfer of assets and data across chains.

Examples of Layers 0

The following blockchain protocols can be classified as true Layer 0 blockchains.

Avalanche

Avalanche is a Layer 0 blockchain that uses the “Avalanche consensus protocol” to provide high-speed transaction processing and low transaction fees. Avalanche aims to provide a robust and efficient infrastructure for building DeFi apps.

Avalanche is built on a tri-blockchain infrastructure that comprises three core chains: the Contract Chain (C-Chain), the Exchange Chain (X-Chain), and the Platform Chain (P-Chain).

Each of these three chains is designed to handle specific functions within the ecosystem, with a focus on enhancing security, low latency, and high throughput. The Exchange Chain (X-Chain) is dedicated to creating and trading assets, while the Contract Chain (C-Chain) is used to create and execute smart contracts. The Platform Chain (P-Chain) serves as the coordinating layer for validators and subnets.

Cosmos

Cosmos is a Layer 0 platform that is built to enable an interconnected network of thousands of blockchains to form the Cosmos Network. One of the main features of Cosmos is the Inter Blockchain Communication Protocol (IBC), which facilitates the exchange of data and assets across the various blockchains in the network. To be compatible with IBC, each independent blockchain must be capable of meeting certain minimum requirements, but there are no limits on network topography or consensus mechanism.

Developers can utilize the Cosmos SDK to construct their own chains and applications within the Cosmos ecosystem.

Polkadot

Polkadot is a Layer 0 blockchain that provides a heterogeneous multi-chain network, enabling the interoperability of multiple blockchain networks. Polkadot uses a unique architecture called “parachains” to achieve high scalability and network security.

Basically, Polkadot is a blockchain protocol that enables developers to build their own blockchains. The Polkadot network consists of a main chain, called the Polkadot Relay Chain, and multiple independent blockchains built on Polkadot, known as parachains.

The Polkadot Relay Chain acts as a bridge between the different parachains, facilitating efficient data communication between them. To increase transaction processing efficiency, the Relay Chain uses sharding, a technique that splits blockchains or databases into smaller, more manageable parts.

By using Polkadot, developers can create their own custom parachains with their own tokens, consensus mechanisms, and other features, while benefiting from the security and interoperability provided by the Polkadot network.

Venom

Venom is a Layer 0 blockchain that aims to tackle the obstacles to the widespread adoption of decentralized applications, such as slow block confirmations, high transaction fees, and limited scalability. It offers a decentralized network based on cutting-edge technology that provides swift, secure, and scalable solutions across multiple industries.

The underlying technology of the Venom blockchain has been tested and proven since its inception in 2017, culminating in the launch of the first stable network, Everscale. This network has achieved a bandwidth of over 54,000 transactions in a close-to-live environment and 4,000 transactions in the mainnet. The community and core development teams have played a vital role in improving the network by implementing new concepts, fixing errors, and enhancing security.
