v0.7.7-venus

v0.7.7-venus

Release for cess-testnet-v0.7.7-venus

Chain

In this upgrade, the chain has introduced or modified several new modules.

The substrate framework has been updated to polkadot-v1.10.1.

Highlights

• The reward rules for miners have been revised to a more fair and reasonable distribution model. Specific rules will be detailed in the economic model to be released later.
• A new reservoir module has been added for lending staked coins to miners.
• The previous practice of purchasing storage space has been replaced. Instead, users can now own and trade multiple "territories."

• Updated the faucet interface and added a whitelist to prevent malicious use of the faucet.

Features

Overview

• Added deoss proxy authorization function.
• Introduced a new upload declaration interface adapted to the territory module.
• Added a function to TEE for refreshing the security level status.

Reservoir (#347)

• Event creation function: Allows official personnel to publish events.
• Participate in events function: Enables miners to borrow tokens for running storage.
• Storage and redemption functions: Used by miners to stake more tokens for operating storage nodes.

Territory (#365)

Each territory will be associated with a unique tokenId for trading:

• Territory casting function: Users can customize the time and size of the territory and assign a name to it.
• Territory trading function: Users can consign their territories for others to purchase.
• Territory transfer function: Users can transfer their territories to others like NFTs.

Highlights

• The new file upload mode allows for faster storage of file data on the chain.
• A more flexible tee registration mechanism with optional options for binding stash accounts.
• Now for compatibility with EVM tokens, the Decimals of CESS tokens have been changed to 18.

Ceseal

Highlights

• Intel SGX technology and Gramine framework are used to ensure program security. The program works as part of the Tee Worker and runs inside the enclave.
• The original and efficient podr2 algorithm and pois algorithm are used to ensure that the CESS bucket node will not cheat during mining.
• Use MRENCLAVE to seal the unique key master key in the entire network, which improves the security level of the system.
• Continuously receive block information from chain nodes and verify it, ensuring that information from outside the enclave is reliable.
• The transfer of information supports http2, which greatly improves efficiency.
• Simplified the code by removing redundant types after merging CESS with TEE.

Features

• Use sr25519 key pair as the master key. The Tee Worker signatures on the chain are all from this key.
• Supports verification and saving of each block information locally.
• The Tee worker now supports synchronization from the genesis block upon restart.
• Use grpc technology for internal and external requests.
• Use podr2 algorithm and pois algorithm.

Cifrost

Highlights

• The health of ceseal will be monitored at any time. If ceseal exits, cifrost will also exit.
• Synchronize with the cess node code type to improve the overall aggregation of the project.

Features

• Supports activation of ceseal initialization and recovery processes.
• Transport block information as a ceseal bridge.

v0.7.5

v0.7.5

Release for cess-testnet-v0.7.5

Highlights

• Added a user-sponsored space purchase feature, supporting users in purchasing space on behalf of others.
• The file upload process and meta-information structure have been optimized, saving 45% of the storage space on the chain, and the file upload speed has been significantly improved.

Optimization

• File upload module code refactored.

Features

v0.7.4

v0.7.4

Release for cess-testnet-v0.7.4

Highlights

📢 Now the substrate framework used by cess has been upgraded to polkadot-v0.9.42 version.

• Random challenges have a new selection mode. It can provide every storage miner with more fair reward opportunities. In order to avoid the impact of storage miners with high computing power on the end time of a challenge round, each storage miner's challenge is now independent. 🦾
• Random challenges no longer punish storage miners whose idle data fails. But at the same time, if the idle data of the storage miner fails, the reward will not be obtained.

Optimization

• Modified the bucket deletion check. The bucket must be empty before it can be deleted.
• Modified the file deletion interface and cancel the batch deletion function.
• Storage miner reward pool is moved from sminer to cess-treasurey pallet.
• Changed a more appropriate file slicing specification.

Features

• A new cess-treasury pallet is introduced to mange cess treasury accounts. There are now three accounts used to manage storage miners' rewards, users' tokens for purchasing space, and tokens for punishing storage miners.
• New random challenge trigger mode to reduce the amount of data in one block.
• To burn the tokens, you can now burn the tokens of cess-treasury accounts through root privileges, but the storage miner's reward pool cannot be burned.

v0.7.3

• Fix the issue where the challenge proposal did not pass.
• Change the number of miners selected for random challenges

v0.7.2

• Fixed event names.
• Modified challenge idle proof calculation rate parameters.
• Modified validation cycle calculation rules.
• Temporarily disabled the rules for removing storage nodes.

v0.7.1

• Fix the issue of generating challenges that repeatedly report events.
• Change the return result of duplicate authorization in OSS.

v0.7.0

v0.7.0

Release for cess-testnet-v0.7.0

Highlights

• Using the new PoIS, the storage node certification space rate is greatly improved.
• Verify the relevant content submitted by the TEE Worker to ensure that the work is executed in the SGX Enclave.

Optimization

• The functions related to miner exit are moved from FileBank pallet to Sminer pallet.
• In order to maintain the code easily in the future, fix some codes that use magic numbers, and use constants uniformly. And some data are calculated based on constants.
  • To ensure ease of future code maintenance, we have addressed sections of code that rely on 'magic numbers,' which are hardcoded numerical values lacking context. We have replaced these 'magic numbers' with well-defined constants, promoting uniformity across the codebase.
• Review and modify areas where there may be overflow or where the calculation result is 0 to ensure that the function can execute normally.
• Formulate some more appropriate bounds for BoundedVec.

Features

• Accounts can now authorize multiple DeOSS gateway.
• Add or modify the transactions and methods involved in the space proof algorithm.
• Separate faucet account and reward pool account.
• Add a new mechanism: After TEE workers complete the verification task, increase the reputation score.

Fix

• The additional pledge after the miner is in debt, the pledge of the debt will be added to the bonus pool.
• Add challenge verification reassignment limit.
  • In order to prevent some miners from being unable to complete the challenge verification work with TEE workers, which ultimately leads to the stagnation of the random challenge process, an upper limit for the number of redistributions has been added.
• Fixed the bug that the order was invalidated due to redistribution during uploading files.
