Explained: What is Layer 0 in Blockchain? Layer Zero Crypto Examples

Introduction

Any blockchain project is built on Layer Zero (or 0), which serves as its fundamental layer. Layer 1 is constructed on top of Layer 0, enabling Layer 1 to function without interruption. Unlike layer 1, it has the “cross-chain interoperability” feature, which means different blockchains can communicate in layer zero.

In the blog below, we go into detail about what is layer 0 and layer 0 examples. Let’s dig in.

In a blockchain, layer zero is the first layer that enables seamless connections between other protocols to create interconnected value chains. It offers a potent and fairly modern substitute for smart contracts. Developers can launch several layer 1 blockchains, each targeting one or two of the scalability trilemma’s dimensions instead of all three, using a layer 0 protocol.

Additionally, these L1 networks can communicate with one another, creating the illusion for the user that they are using just one blockchain.

Key Takeaways

• 
  

  Layer 0 is the base layer on which the entire blockchain ecosystem is built.

  
  


• 
  

  Being a fundamental layer, it supports blockchain in backing up transaction data for numerous layer 1 chains.

  
  


• 
  

  Layer 0 deals with the issues such as scalability and interoperability.

  
  


• 
  

  Some popular layer 0 crypto coins are Avalance, Cosmos, and polkadot.

  
  

On Layer zero networks, software developers can build their own Layer 1, connected to the mainchain; however, they all operate independently. SDKs, or software development toolkits, make the connectivity process possible.

In the blockchain, scalability is one of the biggest challenges. However, layer 0 offers a solution covering digital currency wrapping, enabling individual reward set-up and data validation. It allows cross-chain interoperability with layer 1 networks such as ADA, BTC, and others.

The layer 0 protocol can easily deploy relay networks across several nodes, such as BTC and ETH. It also resolves the scalability issue without creating any hindrance. The protocol allows users to build decentralized applications (dapps), blockchain-centric businesses, mint cryptos, and others.

Layers in Blockchain Technology

The blockchain ecosystem has several layers, such as:

• Layer 0: The foundational technology that allows for the construction of multiple Layer 1 blockchains.


• Layer 1: The fundamental blockchains that programmers use to create applications like decentralized applications (DApps).


• Layer 2: Scaling solutions for Layer 1 blockchains that manage operations outside their transactional loads.


• Layer 3: Applications built on the blockchain, such as wallets, games, and other DApps.

Being that, some blockchain ecosystems can operate without the layers mentioned above and still function properly.

How does Layer 0 work?

Layer 0 protocols operate in different ways, each with its own features and designs. However, layer zero’s primary role is to support different layer 1 chains to maintain smooth transaction operability and backup the data related to them. Multiple layer 1 chains built on the layer 0 protocol operate seamlessly and communicate across different blockchains using cross-chain interoperability.

Additionally, to optimize network topology, it supports several consensus algorithms and P2P systems, including directed acyclic graphs (DAG), proof-of-stake, proof-of-work, proof-of-reputable observations, proof-of-activity, and more.

Examples of Layer 0 crypto

The layer 0 protocols are very different from one another. They are generally concentrated on their objectives. As a result, they have different features and designs that are kept in line with the objectives. Here are some layer 0 blockchain examples:

• 
  Cosmos
  
  Cosmos Hub, a mainnet PoS blockchain, and Zones, specialized blockchains, make up the Cosmos network. In addition to giving each connected Zone a shared layer of security, Cosmos Hub also moves resources and data between them. Programmers can design their own cryptocurrency with distinctive block validation settings and additional features thanks to the extensive customizability options available in each Zone. All Cosmos apps and services hosted in these Zones talk to one another using the Inter-Blockchain Communication (IBC) protocol. As a result, data and resources can be freely transferred between different blockchains.


• 
  Avalanche
  
  Avalanche’s tri-blockchain infrastructure consists Exchange Chain (X-chain), the Contract Chain (C-chain), and the Platform Chain (P-chain). Assets are created and traded on the X-Chain, smart contracts are created on the C-Chain, and validators and subnets are coordinated on the P-Chain. Avalanche’s flexible structure also allows seamless cross-chain swaps.


• 
  Polkadot
  
  The Polkadot Relay Chain serves as the protocol’s main chain. A parallel chain, or parachain, is the term used to describe each independent blockchain built upon it. As a link between parachains, the relay chain facilitates effective data transmission. It uses sharding, a method of splitting databases or blockchains, to improve transaction processing efficiency. Polkadot uses proof-of-stake (PoS) validation to ensure network security and consensus.

Scalability and interoperability are two problems that Layer 0 can solve that are currently plaguing the blockchain. Currently, there are several options available that effectively address related problems. Therefore, layer 0’s true potential has yet to be discovered and evaluated.
