## Content

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.Completely Upgraded Block ExplorerRedesigned information architecture and data presentation logic Enhanced clarity in transaction, block, contract, and address query experiences Data synchronisation and indexing methods closer to mainnet environmentsCross-Chain Bridge System with New UI/UXComplete restructuring of decentralised transaction workflows Clarified transaction and cross-chain management logic Designed for real-world user scenarios, not merely testingConcurrent Execution Engine and Consensus Layer Synergistic UpgradeV4 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.EVM execution environment and gas mechanism upgradesWithin 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.System-Level Upgrade Validation for Cross-Chain InfrastructureThe 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.Synergistic Operation Testing of Ecosystem Applications and Underlying SystemsV4 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 intensityLong-term performance of transaction execution, state updates, and fee modelsCollaborative operation of multi-product systems within the same public chain environmentUser experience and usability issues encountered during authentic operational pathwaysThis constitutes not merely a technical test, but a comprehensive evaluation of both product and systems engineering capabilities. IV. Bitroot V4 Testnet Network Information The following details the complete test environment for Bitroot V4 Testnet: 🔗 Mainnet Connection Information Name: Bitroot Testnet RPC https://dev-rpc.bitroot.co Chain ID: 15881 Native Token: BRT Test Token Claim (Faucet) https://devnet.bitroot.co/faucet Block Explorer https://devnet.bitroot.co/ V. Phased Rollout: Bitroot V4 Testnet Testing Bitroot V4 Testnet represents the final comprehensive test network prior to mainnet launch. Unlike previous testnets, this iteration will progress through a phased rollout and incremental validation approach, ensuring each core functionality undergoes thorough verification in real-world usage scenarios. Through a more granular and extended testing cycle, we aim to empower the community, developers, and node participants to identify issues more deeply, provide feedback, and collaboratively refine the protocol and infrastructure. Testing Phase Schedule Phase One｜Foundational Network and Account Interaction Testing Opening Date: 26 December This phase primarily focuses on validating the foundational capabilities of the Bitroot mainnet, including: Adding the Bitroot V4 Testnet network (RPC / ChainID) Wallet integration and network recognition Basic functionality usage of the browser (Explorer) Native asset (BRT) transfer testing between accounts Transaction packaging, confirmation, and on-chain data traceability During this phase, users may freely add the Bitroot chain, familiarise themselves with fundamental operational workflows, and validate network stability under genuine user interactions. Phase Two｜Cross-Chain Bridge Testing Projected: One week following Phase One completion Upon establishing stable foundational chain operations, official cross-chain bridge testing will commence, prioritising verification of: Bitroot ↔ Cross-chain asset flows between other test networks Transaction latency, stability, and failure handling logic for cross-chain transactions Security under high concurrency and continuous cross-chain scenarios Asset consistency and rollback mechanisms under extreme conditions This phase constitutes a critical preparatory step prior to mainnet launch, laying the foundation for Bitroot's multi-chain ecosystem. Phase Three｜DEX and DeFi Component Testing Expected: Commences following completion of cross-chain testing Subsequently, decentralised exchange and liquidity-related testing modules will be progressively released, including: DEX order matching and price execution Liquidity provisioning / removal (LP) Parallel execution performance under high-frequency trading scenarios Stability of contract invocations, gas fees, and state updates This will serve as a concentrated validation of Bitroot's parallel EVM execution capabilities and suitability for real-world DeFi scenarios. VI. Who Should Participate in Bitroot V4 Testnet? This testnet is open to all users wishing to preview the Bitroot mainnet architecture, including but not limited to: Developers: Testing contract deployment, invocation, and execution performance Ecosystem projects: Pre-adapting products to mainnet-grade environments Community users: Experiencing complete trading, cross-chain, and interaction workflows Every genuine operation and piece of feedback will directly assist Bitroot in further validating the chain's practicality and security prior to mainnet launch. VII. From V4 Testnet to Mainnet The launch of Bitroot V4 Testnet signifies that Bitroot has formally entered the final phase preceding its mainnet release. Following the stable operation of the V4 testnet and the fulfilment of its established objectives, Bitroot will progressively advance: Final confirmation of mainnet parameters and system configurations Preparations for migrating ecosystem products to the mainnet environment Publication of the mainnet launch schedule End The enduring value of blockchain is never determined by the speed of deployment, but rather by the reliability of its foundational architecture and its capacity to withstand the tests of time and scale. Bitroot V4 Testnet represents the ultimate validation of system stability and constitutes the most crucial step before Bitroot's advancement to mainnet. We invite you to join the Bitroot V4 Testnet, to collectively witness and participate in the arrival of the Bitroot mainnet.
