Avalanche/Avax

---

 Avalanche start can be traced back to a file-sharing site called Internet Planetary File System in May of  2018. The group that derived the concept went by the name of "Team Rocket. A team from Cornel  University led by Emin Gün Sirer was assisted by doctoral students Maofan "Ted" Yin and Kevin Sekniqi.  Later, Ava Labs was set up to help support the financial requirements to aid the research.  Avalanche describes itself as an open-source blockchain where people can build decentralized applications and enterprise blockchains. Developers can build their own sub-blockchains on the network using blockchain security while setting their own parameters.  Avalanche has three main branches to help provide a fast and secure network. The first is the exchange chain or called the x-chain. As you probably guessed, this is where you exchange tokens. You can send or receive other tokens through this chain besides Avax, but all transaction fees are paid in Avax. The second branch is the contract chain, which also goes by the c-chain. This is where developers can build dapps and write smart contracts. The coding for this chain is compatible with Ethereum’s code. This means anyone who has a project on the Ethereum blockchain could just copy and paste it to Avax with no conflicts in the coding script. Finally, there is the Platform chain called the p-chain. The p-chain lets people build layer one and layer two blockchains, which are called subnets. This chain is also responsible for keeping track of all the validators for Avalanche and validators for the subnets.
