حول هذه الخدمة

Our Layer-1 Core Protocol Security Assessment evaluates blockchain protocol foundations including consensus behavior, node clients, peer-to-peer networking, validator operations, and governance or upgrade paths. This service is suitable for both custom or consortium chains and public Layer-1 teams that need focused review of the components they operate or control.

What's Included

Consensus mechanism and fork choice review

Node client and protocol implementation security analysis

P2P networking, mempool, and denial-of-service exposure review

Validator infrastructure, key handling, and privilege boundary checks

Genesis, chain parameter, and upgrade governance review

Assessment of custom modules, state machine logic, or protocol extensions

كيف يعمل

1
Architecture and Scope Review
We identify which chain components, clients, validator paths, and governance processes are in scope for your engagement.
2
Protocol Threat Modeling
We map consensus assumptions, trust boundaries, network dependencies, and upgrade risks to focus the review on exploitable failure modes.
3
Manual Review and Validation
We review protocol logic, node behavior, validator operations, and configuration controls, then validate practical attack paths where applicable.
4
Reporting and Remediation Support
You receive prioritized findings, architectural recommendations, and retest guidance for the affected components.
Deliverables
  • Executive summary with protocol risk overview
  • Detailed Layer-1 assessment report
  • Validator, networking, and governance observations
  • Priority remediation roadmap
  • Architecture notes for chain upgrades or custom modules
  • Retest support for remediated findings

لماذا حافظ سيكيور

Protocol-Level Thinking
We assess security assumptions across consensus, networking, validators, and governance rather than isolated code fragments.
Manual Validation
We prioritize manual review of trust boundaries, configuration risks, and protocol behavior that tooling alone may miss.
Operator-Focused Scope
For public chains, we scope work to the components and responsibilities your team actually owns or operates.
Actionable Reporting
Findings are tied to concrete operational and architectural actions, not just theoretical weaknesses.

الأسئلة الشائعة

Do you only assess private or custom chains?

No. We support both custom/private chains and public Layer-1 teams. Public-chain engagements are scoped around the parts your organization controls, such as clients, validator operations, governance, or custom modules.

What is out of scope for a Layer-1 assessment?

Scope is defined per engagement. Third-party infrastructure, components you do not operate, and unrelated dApp or exchange systems are not assumed in scope unless explicitly included.

Do you test protocol upgrades and governance paths?

Yes. Upgrade processes, governance assumptions, signer controls, and parameter change paths are a key part of protocol security review where they exist.
