4.4 Security and Privacy

At GRX Chain, the integrity of the network and the security of user assets are paramount. We are committed to building and maintaining a blockchain infrastructure that instils confidence while addressing privacy considerations within the transparent nature of decentralised ledgers.

Network Security Measures:

• Robust Consensus Mechanism: GRX Chain's Delegated Proof-of-Stake (DPoS) consensus mechanism provides inherent network security, protecting against malicious attacks (e.g., 51% attacks, Sybil attacks) and ensuring high resilience and fault tolerance. Validators are carefully selected and incentivised to maintain network integrity.

• Cryptographic Foundation: The chain is built upon strong cryptographic primitives, ensuring the immutability of transactions and the secure management of digital assets.

• Smart Contract Audits: We prioritise the security of smart contracts deployed on GRX Chain. We strongly encourage all core protocol contracts and dApp developers to undergo rigorous independent security audits to identify and mitigate vulnerabilities before deployment.

• Operational Security: We adhere to best practices in network operations, including robust node security, continuous monitoring for anomalies, and rapid response protocols to potential threats.

• Continuous Improvement: Our dedicated IT team monitors industry best practices, emerging threats, and new security technologies to enhance GRX Chain's defensive capabilities.

Privacy Considerations:

As a public blockchain, GRX Chain operates on a principle of transparency, where transaction data is publicly verifiable. However, we uphold principles of user control and responsible data handling:

• Pseudonymity: Transactions on the GRX Chain are pseudonymous, meaning that while transactions are publicly viewable on the blockchain explorer, they are linked to wallet addresses, not directly to real-world identities, unless voluntarily disclosed by the user in other contexts.

• User Control: You completely control your private keys and personal wallet data. GRX Chain does not store or have access to your private keys.

• Data Protection Adherence: For any off-chain data processed within the GRX Chain ecosystem (e.g., through integrated services or dApps), we advocate for and adhere to strict data protection principles aligned with global best practices (e.g., GDPR principles where applicable).

• Future Privacy Enhancements: As blockchain technology evolves, GRX Chain will explore integrating advanced privacy-enhancing technologies (e.g., zero-knowledge proofs, confidential transactions) to offer users more options for data privacy within the decentralised space.

GRX Chain strives to provide a trusted and secure environment for all its participants through a multi-layered approach to security and a commitment to best practices for user privacy.
