v0.5.0 (MainNet Alpha)

This is the official release for IoTeX blockchain mainnet alpha. In this release, we baked the blockchain which is consisted of the following components:

• Networking layer enables the peer-to-peer communication between IoTex nodes

• Blockchain APIs (through GRPC) allows applications and users to interact with blockchain.

• Ioctl allows users to interact with blockchain in console.

• Consensus runs Roll-DPoS algorithm to select the active consensus delegates among a pool of delegates (who are elected via staking and voting on Ethereum).

• Account protocol processes native IOTX token transfer.

• Ethereum virtual machine (EVM) with smart contracts written in Solidity enables developers to seamlessly port existing DApps here.
