-- ...
+- [C,D] Updated Substrate to polkadot-v0.9.31
 
 ## [4.8.2]
 
 ### Added
 
-- [C,D] New `pallet-ddc-nodes` is added which allows registering a DDC node within the network with specific settings.
-- [C,D] New `pallet-ddc-clusters` is added which allows launching a DDC cluster in the network and managing it.
-- [C,D] New `pallet-ddc-staking` is added which allows making bonds for DDC nodes before joining a DDC cluster.
-- [C,D] New `pallet-ddc-customers` is added which allows depositing tokens and creating buckets for DDC customers.
-- [C,D] New `pallet-ddc-payouts` is added which allows processing payouts to DDC nodes providers based on DAC validation results.
-- New `ddc-primitives` crate with DDC common types definition.
-- New `ddc-traits` crate with DDC common traits definition.
+- [D] New `pallet-ddc-validator` which implements DDC CDN nodes validation and rewarding. You can enable DDC validation providing `--enable-ddc-validation` argument and `--dac-url` argument to specify DAC endpoint. It will only work on the nodes with validation and offchain workers enabled as well.
+- [D] Several calls for `pallet-ddc-staking` to distribute rewards.
+- [D] Third kind of account in DDC Staking for DDC nodes (along with stash and controller).
+- [D] DDC cluster managers access control list in `pallet-ddc-staking` managed by governance.
+- [Zombienet](https://github.com/paritytech/zombienet) configurations to test block building and spawn a network for DDC validation debugging.

-# CereDDCModule
-
-A module for sending any character sequence-based data from wallet A to wallet B in the Network.
-
-## Overview
-
-### Terminology
-
-DDC - Decentralized Data Cloud by Cere Network.
-
-### Goals
-
-Send any character sequence-based data from wallet A to wallet B in the Network.
-* Data can be updated.
-
-## Interface
-
-### Dispatchable Functions
-
-* `send_data` - Transfers character sequence-based data from the function caller's account (`origin`) to a `send_to` account.
-
-### Public Functions
-
-* `stringDataOf` - Get the character sequence-based data data of `AccountId`.
-* `send_data` - Send character sequence-based data an account.
-
-## Usage
-
-* Go to `Developer` -> `Extrinsic submission` sub menu, execute the cereDdcModule's `send_data` method.
-* Go to `Developer` -> `Chain state` sub menu, query chain state of the cereDdcModule's `stringDataOf`.
-
-### Prerequisites
-
-Import the CereDDCModule and derive your runtime configuration traits from the CereDDCModule trait.
-
-### Import Instruction
-
-* Pull ddc-pallet. From project root folder:
-    ```bash
-    git submodule update --remote
-    ```
-
-* Import to frame structure node. In `./Cargo.toml` add:
-    ```rust
-    [workspace]
-    members = [
-    	"bin/node-template/node",
-    	...
-    	"frame/vesting",
-    	"frame/ddc-pallet",
-    	"primitives/allocator",
-    	...
-    	"utils/wasm-builder",
-    ]
-    ```
-
-### Code Snippet
-
-1. In ./bin/node/runtime/Cargo.toml add:
-    ```rust
-    frame-executive = { default-features = false, path = "../../../frame/executive" }
-    ...
-    pallet-cere-ddc = { version = "7.3.0", default-features = false, path = "../../../frame/ddc-pallet" }
-    ```
-
-1. In .bin/node/runtime/src/lib.rs find "construct_runtime!" then add bellow source:
-    ```rust
-    pub use pallet_cere_ddc;
-    ...
-    parameter_types! {
-    	// Minimum bounds on storage are important to secure your chain.
-    	pub const MinDataLength: usize = 1;
-    	// Maximum bounds on storage are important to secure your chain.
-    	pub const MaxDataLength: usize = usize::MAX;
-    }
-    
-    /// Configure the send data pallet
-    impl pallet_cere_ddc::Trait for Runtime {
-    	type MinLength = MinDataLength;
-    	type MaxLength = MaxDataLength;
-    	// The ubiquitous event type.
-    	type Event = Event;
-    }
-      
-    construct_runtime!(
-    	pub enum Runtime where
-    		Block = Block,
-    		NodeBlock = node_primitives::Block,
-    		UncheckedExtrinsic = UncheckedExtrinsic
-    	{
-    		System: frame_system::{Pallet, Call, Config, Storage, Event<T>},
-            ...
-            Multisig: pallet_multisig::{Pallet, Call, Storage, Event<T>},
-            CereDDCModule: pallet_cere_ddc::{Pallet, Call, Storage, Event<T>},
-    	}
-    );
-    ```
-
-### Command List
-* Check before compiling node by command:
-    ```bash
-    cd ./frame/ddc-pallet
-    SKIP_WASM_BUILD=1 cargo check
-    ```
-
-* Run unit test command:
-    ```bash
-    cd ./frame/ddc-pallet
-    SKIP_WASM_BUILD=1 cargo test
-    ```
-
-* Build and run node. From project root folder:
-    ```bash
-    cargo build --release
-    ./target/release/cere --dev --ws-external
-    ```
-
-## Assumptions
-
-Below are assumptions that must be held when using this module.  If any of
-them are violated, the behavior of this module is undefined.
-* The length of string data should be greater than `1`.
-* The length of string data should be less than `usize::MAX`.
-

-* [`Support`](https://docs.rs/frame-support/latest/frame_support/)
