Bitcoin consulting
Crown Citadel Group
We help institutions and operators make sound technical decisions about Bitcoin - across custody, mining, payments, exchanges, privacy, and security. No sales pitch. No product to push. Just independent analysis.
Limited engagements. Written deliverables. No open-ended retainers.
Areas of focus
Custody & key management
Multi-sig architecture, signing ceremony design, and disaster recovery planning. We threat-model your key management before an attacker does.
Payments infrastructure
Lightning integration, on-chain settlement architecture, and liquidity management. We review payment stacks for correctness and operational resilience.
Privacy & security
UTXO management, network-level privacy, and operational security posture. We model adversary capabilities so you can build to the right threat level.
Market structure & exchanges
Exchange integration risk, regulatory constraint mapping, and trading infrastructure controls. We help you understand what you're exposed to.
Education
Board-level briefings, internal team workshops, and written decision memos. We translate protocol-level complexity into executive clarity.
Approach
01
Assess
Constraints, threat model, current-state review. We map what you have, what you're exposed to, and where the gaps are.
02
Design
Options, tradeoffs, written recommendation. You receive a document - not a slide deck - with a clear recommendation and the reasoning behind it.
03
Support
Implementation guidance, verification, knowledge transfer. We stay engaged through execution and make sure your team can operate independently after.
Correctness, security, and clear thinking over hype.
