Security architecture

The Neuro security architecture defines the mechanisms the platform uses to enforce integrity, control access, and maintain trustworthy operations over time. Where the trust model explains who is trusted and why, this page covers how that trust is enforced technically.

​

Cryptographic signatures

Signatures are the primary enforcement mechanism in Neuro. They are used to protect:

• Legal identities — signed by a Trust Provider to verify authenticity
• Smart contracts — signed by all parties and the Trust Provider
• Ledger-backed records — protected against tampering over time
• Token actions — tied to identified, accountable actors
• Platform objects — ensuring integrity across domain boundaries

Signatures provide integrity, traceability, and non-repudiation. An action that was signed cannot be denied later, and a record that has been signed cannot be silently altered.

​

Access control and consent

Access is not assumed by default. The platform enforces controlled interaction based on explicit authorization and consent. This matters for systems where participants need to exchange information or act on shared resources without exposing everything to everyone. Access must be granted — it is not inherited from network membership or domain participation alone.

​

Algorithm agility

Neuro does not lock cryptographic algorithms permanently into its infrastructure. Systems built on the platform are intended to last years or decades — medical records, land registries, sustainability ledgers, and IoT infrastructure all operate on long timescales. Algorithms have practical lifespans, and a platform that cannot evolve its cryptographic methods creates long-term risk. Neuro’s design allows algorithms to be renegotiated and replaced without breaking the trust model or invalidating historical records.

​

Auditability

Important operations in Neuro are designed to be traceable. Signed actions, identity-backed contracts, and ledger records create an auditable trail that supports accountability over time — not just at the moment of execution.

​

Design checklist

When designing with the platform, consider:

• Who the actor is and what identity level is required
• What must be signed and by whom
• What access must be explicitly granted
• What should be recorded for future auditability
• How cryptographic choices will age over the system’s lifetime
