What Is Avalanche(AVAX) ?How It Works? Complete Guides 2024

Avalanche is a blockchain platform that aims to address the blockchain trilemma of scalability, security and decentralization thanks to its unique Proof of Stake (PoS) mechanism.

Like Ethereum, Avalanche supports smart contracts to run decentralized applications (dApps) on its network. Since Avalanche’s smart contracts are written in the Solidity language also used by Ethereum, it aims to create greater blockchain interoperably by integrating a number of decentralized finance (DeFi) ecosystems, including well-established projects like Aave and Curve.
 
AVAX, the native token of the Avalanche platform, is used to power transactions in its ecosystem. AVAX serves as the means to distribute system rewards, participate in governance and facilitate transactions on the network by paying fees.

Who Created Avalanche?

In May 2018, Team Rocket — a pseudonymous group of software developers — published an article that detailed the basis for the Avalanche protocol. Soon afterwards, Emin Gün Sirer founded AVA Labs with the goal of creating and developing the Avalanche blockchain.
 
Sirer is a professor of computer science at Cornell University and was a notable member of the Initiative for Cryptocurrencies and Contracts (IC3). In 2003, he also created Karma, a Proof of Work virtual currency for peer-to-peer file sharing systems that predated Bitcoin.
 
Avalanche raised $42 million through an ICO in July 2020 and has continued to draw big investments since. In July 2021, the Avalanche Foundation held a token sale raising $230 million, with participants including large VC companies such as Polychain and Three Arrows Capital.

How Does Avalanche Work?

Although Avalanche’s platform is complex, there are three primary aspects of its design that distinguish it from other blockchain projects: its consensus mechanism, its incorporation of subnetworks and its use of multiple built-in blockchains.

Avalanche is a blockchain platform designed for high scalability, security, and fast transaction processing. Here’s a breakdown of how it works:

Unique Consensus Mechanism:

• Unlike traditional Proof-of-Work (PoW) or Proof-of-Stake (PoS) used by many blockchains, Avalanche utilizes a novel consensus mechanism called Snowman.
• Snowman combines elements of PoS and Directed Acyclic Graph (DAG) technology.
• In essence, validators randomly sample a small group of their peers to verify transactions. These validators then share the information with their own sampled groups, creating an “avalanche” effect where agreement on the transaction spreads rapidly across the network.

Benefits of Snowman:

• Scalability: This approach allows Avalanche to validate transactions much faster than traditional PoW blockchains, potentially processing thousands of transactions per second.
• Security: The random sampling and rapid information sharing make it difficult for malicious actors to disrupt the network.
• Decentralization: Avalanche utilizes a large number of validators spread across the globe, contributing to a decentralized network.

Subnets:

• Avalanche supports the creation of custom subnets. These subnets can have their own rules and functionalities, allowing developers to build customized blockchain applications without compromising the security of the main Avalanche network.

Avalanche Token (AVAX):

• AVAX is the native token of the Avalanche ecosystem. It’s used for:
  • Paying transaction fees on the network
  • Staking to secure the network and earn rewards
  • Participating in governance decisions on the platform

Overall, Avalanche aims to address scalability limitations of traditional blockchains while maintaining security and decentralization. Its unique consensus mechanism and subnet capabilities make it a strong contender in the world of smart contract platforms.

Avalanche Consensus

In order for a blockchain network to validate transactions and remain secure, it must employ a protocol that allows its nodes to reach agreement — or consensus. With regards to cryptocurrencies, the conversation has centered around Proof of Work (PoW) vs Proof of Stake (PoS) as the leading methods for reaching this agreement.

Avalanche uses a novel consensus mechanism that builds on the PoS foundation. When a transaction is initiated by a user, it’s received by a validator node that samples a small, random set of other validators, checking for agreement. The validators perform this sampling procedure repeatedly, “gossiping” with each other to ultimately reach consensus.

In this way, one validator’s message is sent to other validators, which sample more validators, which sample even more validators – again and again, until the whole system reaches agreement on an outcome. Just as a single snowflake can become a snowball, a single transaction can eventually turn into an avalanche.

Validator rewards scale according to the amount of time a node has staked its tokens, called Proof of Uptime, and if the node has historically acted according to the software’s rules, called Proof of Correctness.

Subnetworks

Avalanche users can launch specialized chains that can operate using their own sets of rules. This system is comparable to other blockchain scaling solutions, like Polkadot’s parachains and Ethereum 2.0’s shards.

Consensus on these chains is reached by subnetworks (or subnets), which are groups of nodes that participate in validating a designated set of blockchains. All subnet validators must also validate Avalanche’s Primary Network.

Avalanche subnets, also known as Avalanche Subnetworks (sometimes abbreviated as Subnets), are a key feature of the Avalanche blockchain platform. They essentially allow for creating custom blockchains built on top of the main Avalanche network. Here’s a deeper dive into how they work:

Concept:

• Imagine Avalanche as a powerful main highway with a secure and efficient infrastructure. Subnets are like designated lanes on this highway, each catering to specific purposes.

Benefits:

• Scalability: Subnets help Avalanche achieve high scalability. By offloading traffic from the main network, subnets can process transactions much faster and handle a greater volume.
• Customization: Subnets offer immense flexibility. Developers can create subnets with custom rules, validator sets, and token economics. This allows for building specialized blockchains optimized for specific applications, like decentralized finance (DeFi) protocols or gaming platforms.
• Security: While subnets operate independently, they inherit the security of the main Avalanche network. This ensures a high level of security for applications built on subnets.

Key Characteristics:

• Validators: Each subnet has its own set of validators responsible for verifying transactions within that subnet. These validators can be a subset of the main Avalanche validators or a completely independent group.
• Blockchains: A subnet can run one or more blockchains tailored to its specific needs. This allows for further customization and optimization within the subnet.
• Interoperability: Avalanche subnets can interact with each other and the main Avalanche network through Avalanche Warp Messaging. This enables seamless communication and data exchange between different subnets.

Use Cases:

• DeFi Applications: Subnets can be used to build high-speed, low-cost DeFi applications that don’t congest the main network.
• Enterprise Blockchains: Companies can create permissioned subnets for private transactions with specific regulatory compliance requirements.
• Gaming Platforms: Subnets can be used to develop scalable and secure blockchain-based games with features like in-game currencies and digital assets.

Built-in Blockchains

Avalanche is built using three different blockchains in order to address the limitations of the blockchain trilemma. Digital assets can be moved across each of these chains to accomplish different functions within the ecosystem.

• The Exchange Chain (X-Chain) is the default blockchain on which assets are created and exchanged. This includes Avalanche’s native token, AVAX.
• The Contract Chain (C-Chain) allows for the creation and execution of smart contracts. Because it is based on the Ethereum Virtual Machine, Avalanche’s smart contracts can take advantage of cross-chain interoperability.
• The Platform Chain (P-Chain) coordinates validators and enables the creation and management of subnets.

Why Does AVAX Have Value?

Like many other cryptocurrencies, Avalanche has a capped supply of 720 million AVAX tokens, half of which were created and distributed during Avalanche’s launch in 2020. The remaining tokens are to be generated by the minting process in the form of staking rewards.
 
Because validator rewards are based on Proof of Uptime and Proof of Correctness, staking AVAX is highly incentivized, which creates a system where the circulating supply of AVAX remains relatively low — even when demand for the token is high.
 
Additionally, unlike other blockchains like Bitcoin and Ethereum, Avalanche’s fees are not paid to validators of the network. Instead, all fees are burned. This further increases the scarcity of AVAX, which is offset by the minting process in an effort to ensure the network’s longevity.

Why use AVAX?

Avalanche offers a high-fidelity, high-security network that balances the speed and cost-effectiveness of transactions, while staying easy to use and reliably decentralized.
 
Any user wishing to explore Avalanche’s offerings may wish to purchase the AVAX token as it’s used to pay for transaction and gas fees, interact with smart contracts and to take advantage of Avalanche’s staking rewards.
 
Those who are interested in Avalanche’s DeFi programs or see potential for other dApps building on the network may want to hold AVAX in order to participate in these projects.

There are several reasons why someone might choose to use AVAX, the native token of the Avalanche blockchain platform:

Transaction Fees and Speed:

• Lower Fees: Compared to blockchains like Ethereum, Avalanche offers significantly lower transaction fees. This can be particularly attractive for users who frequently interact with DeFi applications or make many small transactions.
• Faster Speeds: Avalanche’s unique consensus mechanism enables much faster transaction processing times compared to traditional Proof-of-Work blockchains. This allows for quicker confirmations and a smoother user experience.

Smart Contract Functionality:

• EVM Compatibility: Avalanche is compatible with the Ethereum Virtual Machine (EVM), which means that developers can easily port existing Ethereum smart contracts to Avalanche. This attracts developers who already have experience building on Ethereum and reduces the development time for new applications.
• Subnet Customization: Avalanche subnets allow for building specialized blockchains with custom rules and functionalities. This caters to developers who require specific features or optimizations for their DeFi protocols, gaming applications, or other blockchain projects.

Staking and Earning Rewards:

• Staking Rewards: AVAX holders can stake their tokens to secure the Avalanche network and earn rewards in the process. This provides a way to generate passive income on their AVAX holdings.

Potential for Growth:

• Emerging Blockchain Platform: Avalanche is a relatively new but rapidly growing blockchain platform. As the platform gains traction and more applications are built on it, the value of AVAX could potentially increase.

Here’s a quick recap:

• Lower transaction fees and faster speeds compared to some other blockchains
• EVM compatibility for easier development of smart contracts
• Subnet customization for specialized blockchain applications
• Staking rewards for earning passive income
• Potential for growth as the Avalanche platform evolves
