Welcome to the Aion Wiki!

This wiki is a guide to using the Aion blockchain network.

Repository layout

The Aion implementation is distributed across multiple modules to allow for code reuse:

• The Aion Core contains the main functionality of the Aion network and can be downloaded from the releases page.
• The Aion FastVM is an enhanced Ethereum Virtual Machine provided as a separate module.
• The Aion Miner repository contains code and documentation for mining blocks on the Aion blockchain.
• The Aion Compatible Web3 Api repository provides a Web3 application programming interface for interacting with the Aion blockchain.
• The Aion Java Api repository provides a java programming interface for interacting with the Aion blockchain.

Aion Core Repository Structure

• .git*** The github repository settings.
• mod*** The modular source code of the aion blockchain.
• 3rdParty The 3rd party libraries source code for building the aion module dependent libraries.
• DockerAutomation The settings of the Aion kernel docker image.
• IdeEnv,eclipse The settings of the IDEs.
• blockade The local network setup testing suite.
• gradle* The gradle relate settings and executing files.
• libs The dependent libraries of the Aion kernel including pre-built 3rd party libraries, AVM/FastVM libraries, and other supported module libraries.
• native The native c/c++ dependent libraries of the Aion kernel.
• Jenkinsfile The CI settings.
• aion.sh The Aion kernel launch script.
• script The scripts for building/packing the Aion kernel.
• tooling The tooling for setup the Aion custom network and the staking block signer.
• networks The default network setting of the Aion kernel including the genesis block, protocol settings and the kernel configs.

Modules

The Aion Core is jdk11 module based implementation:

• The [modAionImpl] aion core unity protocol implementation.
• The [modUtil] aion core common library.
• The [modApiServer] aion core api daemon for aion binary api protocol and web3 protocol client.
• The [modBoot] the boostrap lib for aion core.
• The [modCrypto] the crypto library, include blake2b, sha, edcsa, ed25519 etc.
• The [modDbImpl] blockchain key value database implementation, support levelDb, rocksdb, h2 and mongoDb.
• The [modEvtMgr modEvtMgrImpl] event support framework for blockchain kernel.Ref link
• The [modP2p modP2pImpl] peer to peer library support aion wire protocol.Ref link
• The [modTxpool] blockchain transaction pool interface and implementation.Ref link
• The [modRlp] RLP implemention , which is serialization solution for aion core..
• The [modLogger] logger module.
• The [modPrecompile] precompile contract module.Ref link
• The [modBase] The blockchain base components use in the other aion modules
• The [modAvmStub modAvmVersion1 modAvmversion2] The AVM bridge modules for linking the AVM libraries.

Resources

The Aion installation guide is available in the repository README.md file.

This wiki also contains documentation on:

• Genesis Block - description of the network genesis block
• Database - storage configuration options
• Internal Miner - enabling and disabling the internal miner and collecting AION
• Command Line Interface - using the command line options to interact with the network
• Build your Aion network - the guide for build your Aion network step by step.
