Everything You Need to Know About Avalanche Blockchain

Ava Labs created the Avalanche blockchain in 2020 to support decentralized applications, financial services, and other digital tools. They launched it in response to certain limitations common with earlier blockchains like Bitcoin and Ethereum. These include scalability issues, slow transactions, and energy consumption. 

Additionally, Avalanche offers low transaction costs, faster time to finality (the time it takes to confirm a transaction), and the ability to create subnets (customized Blockchain networks). These ingenious qualities, in addition to its compatibility with the Ethereum blockchain network, make it a favorite amongst cryptocurrency developers and users alike. 

In this comprehensive article, we will explain the Avalanche Blockchain and answer important questions, including how the Avalanche consensus mechanism works, key features of Avalanche, how it compares with other blockchains, and more. 

By the end of the article, you should be able to interact with the Avalanche Blockchain and confidently invest in the AVAX cryptocurrency. 

What is Avalanche Blockchain? 

For the sake of cryptocurrency debutants, it is pertinent that we briefly explain what is Blockchain.

A Blockchain is best described as a digital ledger (database) that keeps records of transactions carried out by users within the Blockchain. Many computers share this ledger to ensure that recorded data cannot be changed. 

Since there are several copies of this ledger on different computers, every computer needs to agree on the validity of each transaction. This process is called consensus and can be done in various ways, such as Proof-of-Work and Proof-of-Stake. 

Popular examples of blockchains include Bitcoin, Ethereum, TRON, BNB Smart Chain, and the Avalanche Blockchain, which we’ll discuss.  

The Avalanche network is a layer 1 Blockchain that uses a proof-of-stake (PoS) consensus known as the Snowman Consensus Protocol. Developers can create decentralized applications and deploy them on the Avalanche Blockchain. 

Ava Labs built the Avalanche Blockchain to ensure speed, security, versatility, affordability, and energy efficiency. The entire network runs on its native token called the AVAX. Users pay transaction fees and earn staking rewards using this token.

Most of the other blockchains mentioned above also have these features. However, they have been associated with the well-known Scalability Trilemma when they experience intense user traffic. Using a novel chain architecture, the Avalanche blockchain has been able to solve these scalability issues effectively without sacrificing speed, reliability, and security.

Wondering how it does this? 

Jump to the next section to discover how the Avalanche blockchain works.

How the Avalanche Blockchain Works?

Most blockchains run into scalability issues as their users increase because they depend on a single chain to handle all tasks. 

However, the Avalanche blockchain avoids this difficulty by handling different tasks with three distinct chains. 

These chains include:

1. The X-chain (Exchange chain): The AValanche X-chain generates new assets (AVAX) and facilitates asset exchange and transfers across different chains.
   
2. The C-chain (Contract chain): The Avalanche C-chain runs Avalanche smart contracts. An Avalanche smart contract is a program that works automatically when users meet certain conditions. For example, if you pay for a service on the Avalanche blockchain, you get a digital ticket.
   
3. The P-chain (Platform chain): The Avalanche P-chain manages validators, controls the AVAX staking mechanism, and creates subnets. 

This three-chain architecture makes the Avalanche blockchain lightning fast and highly secure, thus supporting the development and launching of decentralized finance (DeFi) on the Avalanche network. 

How the Avalanche Consensus Mechanism Works

As earlier mentioned, Avalanche uses Proof-of-Stake to validate transactions. This process involves participants known as validators verifying transactions and receiving rewards in return through AVAX staking. The more AVAX you stake, the higher your chances of getting the reward. 

To enhance the Proof-of-stake system, Avalanche uses the Snow family protocols, which are a series of unique consensus algorithms that make the process faster and more reliable. The protocols include:

1. Slush: This is the first process in the series, and it involves validators randomly sampling each other to reach a consensus
2. Snowflake and Snowball: After the slush, validators vote over multiple rounds to solidify their decision.
3. Avalanche: Finally, validators reach a consensus, and transactions are confirmed permanently. 

History of the Avalanche Blockchain

Avalanche began as a breakthrough idea to address the scalability challenges faced by decentralized networks. 

An anonymous group called  “Team Rocket” first introduced the concept for Avalanche in May 2018 through the Interplanetary File Systems (IPFS). Their goal was to design a consensus protocol that could operate reliably even in systems prone to crashes and malicious behavior. This concept was particularly appealing to academics, and soon after, a group of researchers at Cornell University led by Emin Gün Sirer, along with doctoral students Maofan “Ted” Yin and Kevin Sekniqi, took the initiative to develop the concept even further. 

Their research laid the foundation for the Avalanche Blockchain network. 

The Avalanche network sought to meet the demand for reliability, which was necessary for the smooth running of the financial industry. By March 2020, Ava Labs made the AVA codebase open-source. This allowed developers across the globe to contribute to Avalanche’s growth through the AVA Developer Accelerator Program (DAP).

In September 2021, Ava Labs secured over $230 million in funding from prominent investors, including Polychain Capital and Three Arrows Capital, through the sale of AVAX, its native token. Shortly after that, Avalanche partnered with Deloitte to improve the U.S. disaster relief effort. This partnership shot their reputation through the roof, helping them rise into the top 10 cryptocurrencies by market capitalization. 

Avalanche also partnered with Amazon Web Services to enhance its infrastructure and support decentralized applications. Likewise, the smart contracts platform partnered with Arkham Intelligence to strengthen its ecosystem by enabling wallet and entity analysis with its network. 

Key Features of the Avalanche Network

The following are some of the Avalanche Blockchain network’s most defining features, which make it a favorite among crypto developers and users. 

1. Quick Time to Finality

The time to finality refers to the duration required for a transaction to be processed, completed, and verified to be immutable (permanent) on a blockchain network. 

Avalanche can process over 4,500 transactions per second, which is astronomical in comparison to Bitcoin and Ethereum, which process transactions at the rate of 7 and 14 transactions per second, respectively. 

Avalanche’s speed makes it ideal for apps that require instant results, such as those for gaming and financial services. 

2. Ethereum Compatibility 

Avalanche is compatible with Ethereum Virtual Machine (EVM). This means that developers can easily migrate their decentralized apps from Ethereum to Avalanche without rewriting codes. 

Avalanche’s compatibility with Ethereum is a huge win for developers, as it allows them to access the large Ethereum community while offering faster and cheaper transactions. 

3. Subnets and Customization

A subnet is an independent, customized Blockchain that runs on another Blockchain but has its own unique rules. With Avalanche, businesses can utilize subnets to develop customized Blockchains that meet their specific needs. 

4. Improved Security and Reliability

In addition to proof of stake, which helps discourage malicious behavior, Avalanche also provides Byzantine Fault Tolerance (BFT). This technology secures the Blockchain and ensures that it operates optimally even if some computers (nodes) malfunction. Consequently, these security features make the Avalanche network more secure and reliable.

Avalanche vs Ethereum

Even though Avalanche and Ethereum are both Blockchains with smart contract capabilities, they are different in how they achieve speed, scalability, and efficiency. As such, this section will compare the consensus mechanisms, performance, costs, and use cases of both blockchain networks. 

I. Consensus Mechanism

Ethereum started out using Proof of work to validate its transactions. However, it transitioned to Proof of stakes in 2022 to save energy. While the shift from PoW to PoS has made the platform more secure, it hasn’t done much to improve the speed of the validation process. 

This is because of the large number of validators and the complexity of the process. Remember, Ethereum has only one chain. 

On the other hand, Avalanche uses a unique PoS-based consensus that relies on random sampling. This allows for much faster finality, which results in almost instant confirmation, which is typical of the Avalanche Blockchain. 

II. Speed and Transaction Finality 

Ethereum transactions can take between 12 and 15 seconds to confirm. However, this can go up to several minutes during network congestions, prompting users to pay higher fees to prioritize their transactions. 

In contrast, Avalanche takes less than a second to confirm transactions due to its unique consensus mechanism. Even under heavy usage, Avalanche maintains high throughput without major delays. 

III. Scalability 

As the number of Blockchain users increases, the number of transactions on the Blockchain also increases, making the network slower and more expensive. Developers need to scale the blockchain to improve efficiency and optimize costs. 

To solve this scalability issue, Ethereum uses layer-2 scaling to help decongest the Blockchain. While this can improve speed and reduce cost, it can also compromise the blockchain’s security. 

On the other hand, Avalanche is built for scalability through subnets. Avalanche subnets allow multiple Blockchains to run in parallel without slowing down the mainnet. This is why Avalanche can handle thousands of transactions in a second without compromising performance. 

IV. Fees and Costs

This is another aspect where Avalanche edges Ethereum. 

Ethereum is known for high gas fees, which can go up during the high demand. Users may pay as high as $30 in gas fees for a simple transaction, prompting developers and users to be strategic about when they interact with the Blockchain to avoid high costs.

On the flip side, the Avalanche network offers much cheaper fees than Ethereum. A typical transaction costs only a few cents. This is a major attraction for developers and users, especially in DeFi and NFTs

V. Energy Efficiency 

Energy consumption is a big issue in crypto mining, especially for Blockchains that use PoW as their consensus mechanism. These computers used in mining and validation are energy-intensive. With the drive for more responsible energy usage, many stakeholders have become concerned with the energy efficiency of mining cryptocurrency. 

Thankfully, both Ethereum and Avalanche use the Proof-of-stake mechanism for consensus, which is much more energy-efficient than the Proof-of-Work mechanism. However, since Ethereum has a much larger network and is more resource-intensive than Avalanche, it typically requires more energy than Avalanche. 

VI. Security

Both Blockchains take security seriously. 

Ethereum has gone through several upgrades throughout its lifetime to protect against attacks. However, network congestion and high fees can create vulnerabilities in DeFi protocols. 

Avalanche is also very secure, with a robust PoS consensus and decentralization. Its faster finality reduces the chances of double-spending attacks. While security is solid, Avalanche has fewer real-world stress tests compared to Ethereum.

Now that we’ve explored Avalanche vs Ethereum, you may also want to dive deeper into the comparison of Blockchain vs Distributed Ledger to better understand their foundational distinctions.
