Avalanche

Avalanche operates as a layer one blockchain serving as a foundation for decentralized applications and bespoke blockchain networks. It positions itself as a competitor to Ethereum, with the goal of surpassing it as the leading platform for smart contracts. The project seeks to achieve this by delivering transaction throughput of up to 6,500 transactions per second without sacrificing scalability.

This performance stems from Avalanche’s distinct architectural design. The network comprises three separate blockchains: the X-Chain, C-Chain, and P-Chain. Each chain serves a specific function, marking a significant departure from the models used by Bitcoin and Ethereum, where every node validates every transaction. Additionally, Avalanche’s blockchains employ varying consensus mechanisms tailored to their specific use cases.

Following its mainnet debut in 2020, Avalanche has focused on cultivating its own ecosystem of DApps and DeFi protocols. Several Ethereum-native projects, including SushiSwap and TrueUSD, have integrated with the platform. Moreover, the team continues to enhance interoperability between its ecosystem and Ethereum, notably through the creation of bridges.

Ava Labs, the entity behind Avalanche, was established by Cornell University professor Emin Gün Sirer alongside Kevin Sekniqi and Maofan “Ted” Yin, who both hold computer science PhDs from the same institution. Sirer brings extensive experience in cryptographic studies, having conceptualized a peer-to-peer digital currency six years prior to the Bitcoin whitepaper’s publication. He also contributed to research on Ethereum and Bitcoin scaling efforts before The DAO incident in 2016.

The whitepaper resulting from this academic work paved the way for Ava Labs’ creation in 2018. In February 2019, the project secured seed funding from backers including Polychain, Andreessen Horowitz, and Balaji Srinivasan. Later, in 2020, Avalanche completed its initial coin offering in less than 24 hours, accumulating $42 million.

Avalanche seeks to address the blockchain trilemma, which suggests that scaling a blockchain often compromises its decentralization. This limitation frequently leads to elevated gas fees, a common issue on Ethereum.

To tackle this challenge, Avalanche established three interconnected blockchains:

• The Exchange Chain (X-Chain) handles the creation and trading of native AVAX tokens alongside other assets. These tokens adhere to standardized rules, much like Ethereum’s ERC-20 standard, and operate using the Avalanche consensus mechanism.
• The Contract Chain (C-Chain) supports smart contracts and decentralized applications. It features an Avalanche Virtual Machine that mirrors the Ethereum Virtual Machine, enabling developers to port EVM-compatible DApps. This chain relies on the Snowman consensus mechanism.
• The Platform Chain (P-Chain) manages network validators, monitors active subnets, and facilitates the launch of new subnets. Subnets function as groups of validators, akin to a validator cartel. While a single subnet can validate multiple blockchains, any given blockchain is validated by only one subnet. This chain also utilizes the Snowman consensus mechanism.

By distributing computational responsibilities, the network achieves greater throughput while maintaining decentralization. For example, private blockchains within the ecosystem can mandate that their subnet validators meet specific geographic decentralization criteria or regulatory standards. This modular design enhances interoperability with other blockchains looking to join the Avalanche ecosystem. Additionally, the two distinct consensus mechanisms are tailored to the specific needs of each blockchain, boosting overall efficiency.

Avalanche has a total supply of 720 million AVAX. The allocation of these tokens is broken down as follows:

• 2.5% for the seed sale, where 10% became available at mainnet launch and the remaining balance is distributed every three months.
• 3.5% for the private sale, with 10% released at mainnet launch and the remainder distributed every three months.
• 10% for the public sale, with 10% released at mainnet launch and 15% distributed every three months across an 18-month timeframe.
• 9.26% reserved for the foundation, to be released over a ten-year period.
• 7% for the community endowment, released over twelve months.
• 0.27% for the testnet incentive program, released over one year.
• 5% for strategic partners, released over four years.
• 2.5% for airdrops, released over four years.
• 10% for the team, released over four years.
• 50% designated for staking rewards.

At present, staking AVAX yields an annual reward rate of 11.57%. To participate, users must stake a minimum of 2,000 AVAX for at least two weeks.

AVAX trades on the Exchange Chain, which utilizes a distinct Avalanche consensus mechanism. This approach differs from proof-of-work or proof-of-stake systems because it lacks a single leader who processes transactions for others to validate. Rather, every node handles and verifies transactions using a directed acyclic graph (DAG) protocol. This structure enables simultaneous transaction processing, while random polling by validators confirms accuracy with statistical certainty. Since this consensus model does not use blocks, it allows for immediate finalization and greatly enhances the blockchain’s speed.

You can trade AVAX on Kucoin, Gate.io, Bitfinex, and Binance.

The Avalanche network features three main built-in blockchains.

The X-Chain is dedicated solely to sending and receiving funds on the Avalanche network. It utilizes directed acyclic graph (DAG) technology, offering faster speeds than the C-Chain, with transaction fees fixed at 0.001 AVAX.

This chain handles staking AVAX and managing validator activities. On the P-Chain, users can either become validators themselves or delegate to one to earn AVAX rewards.

Designed for decentralized finance, the C-Chain supports smart contracts and DeFi applications. Most Avalanche DApps operate here and are compatible with MetaMask.

A special subnet known as the Primary Network secures and validates these three networks. To validate on the Primary Network, custom subnets must stake a minimum of 2,000 AVAX.

Subnets, or subnetworks, are dynamic groups of validators that reach consensus on the state of specific blockchains. While each blockchain is validated by a single subnet, one subnet can validate multiple blockchains, and validator nodes may participate in several subnets simultaneously.

Validators are incentivized to meet the specific security and resource needs of each subnet. These incentives, which subnets can customize, may include governance mechanisms and token rewards.

According to the team, Subnets aim to introduce application-specific networks to the wider Avalanche ecosystem. For instance, if a service or product requires particular validator attributes like internet bandwidth or memory, validators meeting those criteria can join the Subnet to ensure efficient operation. Furthermore, Subnets allow for customized fee markets and native token economies.

Avalanche Subnets also enable private blockchain development involving predefined validators. Only these designated validators can view the content of such private blockchains, providing a solution for organizations needing to keep sensitive data confidential.
