1.1 aelf Enterprise v0.8.0 beta

A complete blockchain system, including minimized blockchain kernel, DPoS consensus mechanism, smart contract, voting, token, and basic cross-chain systems.

High-Performance Smart Contract Runtime

Contract execution level: Based on Protobuf, a smart contract execution environment like GRPC is implemented. The input and output of all objects and their storage are all based on protobuf high-performance serialization. Stateful storage uses a high-performance distributed database such as Redis.
Overall contract construction: Generate code through the GRPC plugin, performance is equivalent to the GRPC server.
Contract scheduling: Parallel execution within blocks, parallel execution through AKKA cluster operations.

Consensus System

Security: Ensures that all accounting nodes perform distributed random number generation through The Secret Sharing algorithm. Through this random number, the order of each round of billing nodes is randomly sorted, which reduces the possibility of node collusion.
Efficient: After verifying a block at 2/3 nodes, the block becomes an irreversible block, and the data is permanently stored to the chain without being reversed by the fork.

Multiple Token System

Based on the contract system, a built-in Token system capable of cross-chaining is implemented. All assets are capable of issuing transfer locks and cross-chain transfers.

Voting System

Based on the contract system, a universal voting system has been established, which facilitates online governance and secondary development.

Cross Chain System

Provides a mechanism for any data on the chain to be transmitted across the chain. The system is implemented based on the Merkle Tree Root index, and the whole system can incorporate multi-level main side chain index, allowing scale up and scale out options.

Web API

ASP.Net Core server is implemented to create a high-performance interactive framework.

1.2 DevKit

https://github.com/AElfProject/aelf-boilerplate

Includes development templates and tutorials, developer manuals, TestKit, BenchmarkKit, IDE Integration

Developer’s Manual: Provides a detailed introduction of the AElf system and API documentation
TestKit: Convenient for developers to test contracts quickly
BenchmarkKit: Provide built-in performance test cases
IDE Integration: Enables developers to debug smart contracts in real-time and provides the ability to prompt unit test code coverage

Developers can quickly deploy aelf-based blockchain systems and create Dapps based on development kits and tools provided by aelf, and quickly become familiar with aelf through developer documentation.

2. aelf External Applications

aelf Blockchain Scanner https://github.com/AElfProject/aelf-block-scan

The chain sweeping program makes it easy for developers to store data on and off the chain, reducing developing costs.
Need to insert the application with the corresponding database, the community provides aelf-scan-MySQL as the default MySQL insert version

aelf Scanner MySQL plugin https://github.com/AElfProject/aelf-scan-mysql

Convenient for developers to use the scan chain program to insert data into the MySQL database
Transaction, block, TPS, resource data storage are supported by default

aelf Explorer https://github.com/AElfProject/aelf-block-explorer

Implemented block and transaction queries

aelf Wallet https://github.com/AElfProject/aelf-web-wallet

Store private key locally
Implemented basic token transfer and transition history querying
Searchable and able to add aelf contract tokens

aelf JS SDK https://github.com/AElfProject/aelf-sdk.js

The cross-link transfer interface of aelf is encapsulated to facilitate developers to get started quickly.

aelf CLI in Nodejs https://github.com/AElfProject/aelf-command

A huge amount of instruction prompts are provided.
Provides functions such as creating accounts, obtaining block information, trading information, and creating contracts.
