# 1st Report Of September 2026

September 10, 2026

### Mainnet Performance

* Validator nodes: 99
* Miner nodes: 1,097
* Wallets (net change): +126

### Project Progress

#### 1. New EVM Chain Trial Run & Basic Functionality Verification

**EVM Mainnet Trial Run**

* MATRIX's new EVM chain entered the trial run phase.
* Completed deployment and synchronization testing of core network nodes.
* Verified basic EVM compatibility capabilities:

            Standard address transfers

            ERC-20 contract deployment

            ERC-721 / ERC-1155 contract deployment

            Smart contract invocation

* Conducted continuous testing on Gas calculation, block generation, and transaction confirmation mechanisms.

**Wallet & Developer Tool Compatibility Testing**

* Completed basic MetaMask integration testing.
* Verified standard EVM RPC interfaces.
* Tested Web3.js / Ethers.js SDK compatibility.
* Established basic configurations for test environment Chain ID, RPC, and Explorer.
* Conducted mapping tests from legacy MATRIX wallets to new EVM addresses.

#### 2. EEG-Centric PSG Data Standard Upgrade

**Time Synchronization Mechanism**

* Established device time calibration mechanisms.
* Tested multi-device time offset compensation solutions.
* Implemented millisecond-level Timestamp infrastructure.
* Designed a unified Time Sync API.

**EEG Base Data Preprocessing**

* Initial implementation of:

            EEG noise filtering

            Basic artifact removal

            Signal stability detection

* Built the EEG Channel Mapping test module.
* Tested electrode arrangement compatibility across different devices.
* Reserved extension fields for subsequent PSG-Lite and multi-modal device integration.

#### 3. Biological Data Metadata Infrastructure

**Established basic Device Metadata fields:**

* Device Manufacturer
* Device Model
* Firmware Version
* Sensor Type
* Sampling Rate
* Battery Status

**Defined Session Metadata description structure.**

**Established basic mapping between Device ID and Session ID.**

**Reserved fields such as Hash, Owner, and Timestamp for future on-chain biological data registration.**
