Because the PRODAO Mainnet must stably support core features such as decentralized expert services, the A2E reward system, and DID-based MyData, network security is an element that must be secured as the highest priority. To protect the network from various cyberattacks and system errors and to keep user assets safe, PRODAO establishes and executes a systematic vulnerability-analysis and response strategy.
10.1. Network Security Vulnerability Analysis and Response
The PRODAO Mainnet establishes comprehensive and advanced measures to maximize the security of the network layer and to proactively respond to potential vulnerabilities.
- Optimal network architecture: Through an architecture with highly distributed node deployment and strong redundancy, the PRODAO Mainnet fundamentally blocks single points of failure and secures the highest level of resistance to DDoS (Distributed Denial of Service) attacks and Sybil attacks.
- Leading consensus-mechanism security: Through its unique characteristic of being based on the contributions of network participants, PRODAO's PoC (Proof of Contribution) consensus algorithm provides strong resistance to certain types of attacks that existing PoW (Proof of Work)- or PoS (Proof of Stake)-based networks may face. In addition, upon detecting malicious behavior, it firmly ensures network integrity through an immediate slashing mechanism.
- Regular penetration testing and in-depth vulnerability analysis: Through cooperation with world-class security specialist institutions, PRODAO performs regular penetration testing and in-depth vulnerability analysis of the PRODAO Mainnet's network infrastructure, protocols, and all inter-node communication paths to identify and remove potential threats in advance.
- Intelligent security monitoring and rapid updates: Using AI-based systems, PRODAO monitors network traffic, node status, anomalies, and the like in real time to immediately detect and respond to potential threats. Discovered vulnerabilities are patched quickly as the top priority, and updates are deployed after rigorous verification procedures, maintaining optimal security stability.
- Top-level secure communication and node management: All inter-node communication is fully protected through strong encryption protocols. In addition, PRODAO provides Signer node operators with the highest level of clear guidelines for strengthening hardware and software security, further raising the security level of the entire network.
- Proactive incident response plan: PRODAO establishes a clear and efficient Incident Response Plan to minimize damage and quickly recover the system in the event of a network security incident, and strengthens its response capabilities through periodic drills.
10.2. Smart Contract Security Audit Plan
All of PRODAO's core smart contracts implement a systematic, multi-layered audit plan to guarantee the highest level of security integrity. (For the detailed methodology, see 7.4. Security Audits and Vulnerability Management.)
- Complete pre-deployment security audits: Before the PRODAO Mainnet launch, and before all core smart contracts are deployed, PRODAO always commissions a comprehensive security audit from an independent external specialist audit institution with a high reputation in the field of blockchain security. This focuses on perfectly identifying and removing all known vulnerabilities—such as reentrancy attacks, integer overflow/underflow, and access-control issues—in advance.
- Continuous re-auditing and ongoing review: When platform features are expanded or smart contracts are updated, PRODAO performs a rigorous re-audit of the relevant contract, and it also conducts periodic security checks and in-depth code reviews of already deployed contracts to actively respond to the latest security threats.
- Operating a global bug bounty program: PRODAO permanently operates a bug bounty program that pays exceptional rewards when ethical hackers and security researchers around the world discover and responsibly report potential vulnerabilities in PRODAO smart contracts. This is an effective method of innovatively strengthening security by leveraging the collective intelligence of the global security community.
- Transparent disclosure of audit reports: PRODAO transparently discloses the external audit reports of its core smart contracts to secure the community's trust and to raise the verifiability of PRODAO's security to the highest level.
- Compliance with proven best practices and global standards: By actively using broadly verified open-source security libraries such as OpenZeppelin and thoroughly complying with global best practices and standards in smart-contract development and security, PRODAO maximizes the stability and reliability of its code.
10.3. Data Protection and Privacy Security Policy
PRODAO prioritizes the safe protection of experts' sensitive data and personal information, and it makes it a core principle to firmly guarantee users full control over their own data.
- Realizing DID-based data sovereignty: All of a user's identity information and personal data is managed on a DID basis, and the user has absolute ownership and control over their own data. Sensitive data is not stored directly on-chain; only the data's hash value or reference information is recorded on the blockchain, perfectly guaranteeing the integrity of the data.
- Consent-based data-use principle: No user data is used within the PRODAO platform or provided externally without explicit, granular consent. The data access and use contract manages the user's consent process with perfect transparency and provides a powerful mechanism to withdraw consent at any time.
- Strong encryption and strict access control: All sensitive data (stored off-chain) shared within the PRODAO ecosystem with user consent is protected by applying the highest level of encryption protocols both in transit and at rest. In addition, PRODAO strictly enforces role-based access control and the principle of least privilege to thoroughly restrict data access.
- Proactive data anonymization and pseudonymization: Datasets that may be used in the data marketplace and elsewhere undergo thorough anonymization or pseudonymization so that individual identification is impossible. This is a core mechanism of PRODAO that maximizes data utility while perfectly guaranteeing privacy protection.
- Introduction of leading privacy-enhancing technologies (PETs): By actively introducing cutting-edge privacy-enhancing technologies such as Federated Learning, PRODAO enables AI models to be trained and analyzed without centralizing the original data, fundamentally blocking the risk of personal-information leakage and presenting a new paradigm of data use.
- Global regulatory compliance: PRODAO thoroughly complies with all relevant legal requirements and international standards, including GDPR (General Data Protection Regulation) and related national data-protection laws, to protect user data and firmly establish PRODAO's legal responsibility and reliability.
- Raising security awareness and education: PRODAO conducts regular and in-depth security education for the PRODAO team, Signer node operators, and community members to raise awareness of the latest security threats and to mandate compliance with PRODAO's strong security policies.
