Throughout multiple testing phases, Bitroot has completed ongoing validation of its underlying architecture, parallel execution engine, and EVM compatibility. From its initial functional validation testnet to progressively feature-rich iterations, Bitroot's technology and product form are rapidly maturing.

Today, we formally announce:

Bitroot V4 Testnet is now live.

This represents Bitroot's final testnet deployment prior to mainnet launch, offering the closest approximation to the actual mainnet environment.

Unlike previous V1/V2/V3 testnets, V4 Testnet transcends mere technical validation upgrades. It constitutes a comprehensive system-level restructuring and integration test geared towards mainnet readiness.

I. What is Bitroot V4 Testnet?

Bitroot V4 Testnet operates under mainnet assumptions as the final testing iteration. Its core objectives have shifted from ‘functional viability’ to:

System stability and long-term operational capability

Product completeness and authentic user experience

Interoperability and consistency across all ecosystem modules

In essence:

V4 Testnet represents a comprehensive dress rehearsal for Bitroot's mainnet architecture, rather than an experimental trial.

At this stage, Bitroot will cease introducing frequent radical experimental features, instead prioritising stability, uniformity, and sustainability as core design principles.

II. Key Differences Between This V4 Testnet and the Previous Three

Compared to prior testnets, Bitroot V4 Testnet represents a comprehensive upgrade from the ground up. The focus extends beyond the chain itself, encompassing the entire product layer and interaction layer.

1. Completely Upgraded Block Explorer

Redesigned information architecture and data presentation logic

Enhanced clarity in transaction, block, contract, and address query experiences

Data synchronisation and indexing methods closer to mainnet environments

1. Cross-Chain Bridge System with New UI/UX

Complete restructuring of decentralised transaction workflows

Clarified transaction and cross-chain management logic

Designed for real-world user scenarios, not merely testing

1. Concurrent Execution Engine and Consensus Layer Synergistic Upgrade

V4 Testnet conducts the first systematic validation of Bitroot's parallel execution architecture under near-mainnet parameters, focusing on:

Stability and throughput performance of parallel transaction scheduling under high concurrency

Coherence between parallel execution and block production workflows

Deterministic behaviour of block generation and finality confirmation under complex loads

Synchronisation efficiency and self-recovery capabilities of nodes during abnormal states (disconnections, reconnections, state inconsistencies)

The core objective of this phase is to validate whether parallelised execution can maintain stable collaboration with the consensus layer under long-term operational conditions.

1. EVM execution environment and gas mechanism upgrades

Within the V4 Testnet, Bitroot's EVM execution environment enters mainnet-level compatibility and security testing:

Verification of full compatibility for mainstream EVM smart contracts on Bitroot

Execution stability under high-complexity contracts and multi-contract interaction scenarios

Consistency and predictability of gas metering rules under parallel execution conditions

Stability and boundary testing of the gas fee model across varying load intervals

The focus of this phase is not merely ‘EVM support’, but verifying:

Whether EVM maintains mainnet-grade security and determinism within a parallel execution architecture.

1. System-Level Upgrade Validation for Cross-Chain Infrastructure

The cross-chain module is no longer tested as an isolated feature on V4 Testnet, but integrated into collaborative validation of the underlying system:

Integrity of cross-chain asset flows between Bitroot and other public chains

Security and stability of cross-chain bridges under high-frequency, continuous usage scenarios

Verification of asset security and rollback mechanisms under extreme conditions (abnormal interruptions, state inconsistencies)

Consistency testing between cross-chain state and Bitroot on-chain state synchronisation

The objective of this phase is to ensure the cross-chain system does not become a source of systemic risk under mainnet conditions.

1. Synergistic Operation Testing of Ecosystem Applications and Underlying Systems

V4 Testnet incorporates deployed ecosystem applications into comprehensive system load testing, including but not limited to:

Real-world trading behaviour testing for decentralised exchanges (DEXs)

Complete business processes including liquidity provision, withdrawal, and LP management

On-chain performance under concurrent multi-DApp operation

Real-time availability and consistency of on-chain data for block explorers and third-party tools

III. Core Focus Areas for V4 Testnet Testing

During the Bitroot V4 Testnet phase, testing will primarily focus on the following aspects:

• Stability of the parallelised EVM public chain under real-world usage intensity

• Long-term performance of transaction execution, state updates, and fee models

• Collaborative operation of multi-product systems within the same public chain environment

• User experience and usability issues encountered during authentic operational pathways

This constitutes not merely a technical test, but a comprehensive evaluation of both product and systems engineering capabilities.
