DeepBrain Chain is undergoing a system upgrade. The new version of the system is based on Polka Substrate v.0.9.37 and will support the upcoming new version of on-chain features. After the upgrade, the old version of the POS block-producing node will no longer be supported. The upgrade must be completed within the next week to avoid the node being unable to produce blocks and generate DBC income.

The new version introduces several important features and improvements, including a new feature for efficient data processing with storage values, safe arithmetic operations, improvements in tracking inactive funds, a new RPC API method for better tracking and querying of blocks, several runtime improvements, and new features such as bridging, cross-chain locking, NFTs, conditions, and context tracking in XCM version 3.

Event date: Jan 30 to Feb 6, 2024 UTC

The new version of the DBC POS block-producing node is being upgraded. Please complete the upgrade within the next week!
The DBC underlying system is being upgraded. The new system version is developed based on Polka Substrate v0.9.37 and supports the upcoming new version of on-chain features. Moreover, the new chain version, after the upgrade, will no longer support the old version of the POS block-producing node. Please complete the upgrade within the next week, otherwise, it will lead to the node being unable to produce blocks and generate DBC income.

The new version introduces several important features and improvements:

1. StorageStreamIter: A new feature that makes data processing with storage values more efficient.

2. Ensure-ops series methods: These methods provide safe arithmetic operations, exposed through traits, and can be used for pallet Config types.

3. Inactive funds tracking improvement: Improvements in tracking inactive funds, including migration logic to ensure correct tracking of inactive issuance.

4. Implementation of chainHead RPC API: A new RPC API method for better tracking and querying of blocks.

5. Runtime improvements: Includes several low-impact improvements and medium-priority changes, such as deploying scheduler agenda cleanup migration and optional runtime upgrade checks.

6. XCM version 3: This version allows new features such as bridging, cross-chain locking, NFTs, conditions, and context tracking.
