NexArt produces Certified Execution Records that bind inputs, outputs, and context into tamper-evident proof. Verifiable by anyone, independently.
Logs describe. They do not prove.
Logs can be edited, deleted, or fabricated after the fact. Inputs and outputs are rarely bound together. When something goes wrong, there is no verifiable link between what was requested and what was returned. Without execution-level evidence, trust depends entirely on the operator.
Execution evidence that anyone can verify
Every execution produces a Certified Execution Record (CER) that binds inputs, parameters, and outputs into a single tamper-evident artifact. Independent attestation nodes verify integrity and issue signed receipts. Recompute the hash. Check the signature. No API key, no account, no dependency on NexArt.
How It Works
Capture — Inputs, outputs, and execution context recorded at runtime.
Seal — SHA-256 hash binds all protected fields into a tamper-evident record.
Attest — Independent node signs the record with an Ed25519 receipt.
Verify — Anyone recomputes the hash and confirms independently. No account required.
Use Cases
AI agents — Verifiable decision trails for autonomous tool calls and multi-step agent workflows.
Multi-step pipelines — Certify every step in tool-calling pipelines so each action produces verifiable evidence.
Approvals and policy checks — Prove that a decision followed the right inputs, parameters, and policy constraints.
Regulated workflows — Audit-grade execution records for regulated industries and compliance-sensitive operations.
Reproducible AI operations — Publish computations with cryptographic proof that results can be independently confirmed.
