The Exchange Chain (X-Chain)
Is the default blockchain on which assets are created and exchanged. This includes Avalanche’s native token, AVAX.
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.
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.
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 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 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.
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.
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.
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.
