Implement and Manage Blockchain Networks
Overview
This standard defines the competencies required to implement and manage blockchain networks and supporting digital-trust infrastructure. It covers node configuration, consensus management, network monitoring, and operational support for decentralised infrastructure, including Layer-2 rollup nodes, off-chain execution components, and cross-chain connectivity.
Professionals applying this standard ensure the secure, reliable, and efficient operation of blockchain networks across organisational and industry contexts. They manage consensus mechanisms, peer connectivity, gossip-based propagation, DAG (Directed Acyclic Graph)-based mechanisms, and decentralised-identity trust flows.
This standard is intended for network engineers, system administrators, operations specialists, and technical professionals responsible for blockchain and distributed-ledger infrastructures, including hybrid and cross-chain environments.
Performance criteria
You must be able to:
- Configure blockchain network nodes to meet platform, security, and operational requirements, including validator, Layer-2, and off-chain execution components.
- Manage consensus parameters and trust-model assumptions to support secure and reliable network operation, including gossip-based and DAG-based mechanisms.
- Monitor blockchain network performance to detect issues in peer-to-peer, Layer-2, and cross-chain activity.
- Manage network events and node failures to maintain consistency and service availability across Layer-1, Layer-2, and off-chain components.
- Apply network security controls to protect nodes, keys, communication channels, and verification processes, including anti-eclipse and cross-chain controls.
- Document network configurations, trust assumptions, and security settings in line with organisational requirements.
- Work with technical, governance, and security teams to support network deployment, monitoring, and assurance activities, including digital-trust and cross-chain validation.
Knowledge and Understanding
You need to know and understand:
- Blockchain network architectures and components, including validator nodes, rollup nodes, sequencers, and cross-chain verifiers.
- Node-configuration requirements, including peer discovery, network hardening, trusted-peering, and anti-eclipse protections.
- Consensus mechanisms, including Proof-of-Stake, BFT variants, DAG-based models, and gossip propagation.
- Network-monitoring methods, including peer-to-peer metrics, gossip-latency indicators, rollup proof activity, and cross-chain traffic.
- Incident-response procedures for consensus divergence, node isolation, replay attacks, and Layer-2 or bridge failures.
- Security controls, including key-management, validator-hardening, reputation systems, secure RPC configuration, and cross-chain verification protection.
- Documentation requirements, including trust boundaries, state-synchronisation assumptions, consensus settings, and audit trails.
- Collaboration methods for working with developers, cybersecurity teams, governance bodies, and auditors.
- Regulatory and organisational requirements influencing blockchain network governance.
