Release CESS v0.3.0 version and submit the proposal for the multi-replica storage proof mechanism.

1. Important Submissions, Modifications, and Releases

Regarding the CESS Chain:

1. Release of CESS v0.3.0

https://github.com/CESSProject/cess/releases/tag/v0.2.0

The version includes the CESS chain and decentralized cloud storage system module, implementing the following features:

1) Completed the design and development of the miner penalty mechanism, including penalty rules, additional collateral, freezing, exiting, and other functions;

2) Optimized the on-chain file routing interface;

3) Implemented the feature for new users to claim free storage space;

4) Completed the writing of the operation manual for miner exit, miner deposit redemption, and reward mechanism;

5) Updated the file metadata interface to support uploading struct type parameters;

6) Fixed the Benchmark compilation bug;

7) Completed the addition of the smart contract module and initiated testing of smart contract calls to the Substrate pallet;

8) Optimized the on-chain reward mechanism bug, fixing the issue where 20% rewards were still sent after the miner was frozen;

9) Completed the configuration scheduling for pallet-cess-staking;

10) Implemented the OnUnbalanced trait for pallet-sminer to receive newly issued tokens to accounts generated by the pallet.

2. Continued development of the CESS Random Selection Rotating Consensus Mechanism (R²S). Completed optimization of the block generation module and the calculation and distribution of periodic incentives.

3. Started designing CESS v0.4.0

1) The goal is to implement a multi-replica recoverable storage proof mechanism, consensus mechanism, and optimize the decentralized cloud storage system to further enhance system security;

2) Summarized improvement requirements based on the testing report and added them to the new version feature list;

3) Updated the decentralized cloud storage design documentation, including system architecture diagrams, upload processes, download processes, purchase processes, deletion processes, encryption and key management, replication proofs, space-time proofs, scheduling service system architecture diagrams, overall client architecture diagrams, and overall storage miner architecture diagrams.

Regarding the CESS Distributed Cloud Storage System:

Debugged the scheduler's storage proof reading and verification functions, fixing several vulnerabilities;
Optimized various exception handling processes in the file processing workflow of the scheduling service program, including memory read/write, file download panic reports, and more.
