Why we create this repo

This repo is forked from bnc-cosmos-sdk.

The AXC Flash Chain leverages cosmos-sdk to fast build a dApp running with tendermint. As the app becomes more and more complex, the original cosmos-sdk can hardly fit all requirements. We changed a lot to the copied sdk, but it makes the future integration harder and harder. So we decided to fork cosmos-sdk and add features onto it.

Key Features

1. Native Cross Chain Support. Cross-chain communication is the key foundation to allow the community to take advantage of the AXC Flash Chain and AXC Chain dual chain structure.
2. Staking. Staking and reward logic should be built into the blockchain, and automatically executed as the blocking happens. Cosmos Hub, who shares the same Tendermint consensus and libraries with AXC Flash Chain, works in this way. In order to keep the compatibility and reuse the good foundation of FC, the staking logic of AXC is implemented on BC. The AXC validator set is determined by its staking and delegation logic, via a staking module built on BC for ASC, and propagated every day UTC 00:00 from BC to AXC via Cross-Chain communication.
3. Rewarding. Both the validator update and reward distribution happen every day around UTC 00:00. This is to save the cost of frequent staking updates and block reward distribution. This cost can be significant, as the blocking reward is collected on BSC and distributed on BC to AXC validators and delegators.
4. Slashing. Slashing is part of the on-chain governance, to ensure the malicious or negative behaviors are punished. AXC slash can be submitted by anyone. The transaction submission requires slash evidence and cost fees but also brings a larger reward when it is successful. So far there are two slashable cases: Double Sign and Inavailability.
5. ParamHub && Governance. There are many system parameters to control the behavior of the AXC Flash Chain and AXC Chain, e.g. slash amount, cross-chain transfer fees. All these parameters will be determined by AXC and BC Validator Set together through a proposal-vote process based on their staking. Such the process will be carried on cosmos sdk.
6. Performance Improvement Parallelization, dedicated cache, priority lock and many other program skills are applied to improvement the capacity of AXC Flash Chain.
