When RBI or SEBI asks for your AI decision trail, can you produce it within 24 hours?
AI regulations don't ask whether you used AI. They ask whether you can prove how decisions were made. Blocklog automatically creates tamper-evident evidence that stands up to regulatory audits.
Logs are claims.
Blocklog makes them proof.

#EP-2024-0847 · Q3 Audit Cycle
From deployment to audit-ready evidence
in three steps.
Blocklog captures, chains, and stores every AI decision automatically. No batch jobs. No manual exports. No gaps in your evidence trail.
Instrument your application.
Add the Blocklog SDK with a single import. One line captures every AI decision — model version, inputs, outputs, and context — without changing existing behavior.
import { blocklog } from '@blocklog/sdk';
const result = await blocklog.trace({
fn: () => openai.chat.completions.create(params),
context: { userId: 'usr_881', workflow: 'credit' }
});Blocklog creates immutable audit evidence.
Each event is hashed with SHA-256, chained into a Merkle tree, and stored in an immutable audit log. Tampering with any record breaks the entire chain.

}Generate regulator-ready reports instantly.
When regulators ask, export a complete, cryptographically verified evidence package in minutes. Includes model cards, decision logs, and bias reports.
const pkg = await blocklog.evidence.export({
period: 'Q3-2024',
format: 'pdf+json',
include: ['decisions', 'biasReport',
'provenance', 'accessLog']
});Who is Blocklog for?
If your organisation uses AI to make decisions that affect people, you have a regulatory obligation to prove how those decisions were made.

Proof, not promises.
Published benchmarks, open architecture, and no proprietary black boxes. You should be able to verify everything Blocklog claims.
audit events/hour
Production-tested ingestion pipeline. Handles peak load from enterprise AI workloads without dropping events.
verification latency
Any evidence record can be independently verified in under 200ms. Cryptographic proof without waiting.
hash algorithm
Every record is hashed with SHA-256 and chained to its predecessor. Industry-standard cryptography, no proprietary schemes.
proof generation
Tamper detection at scale. Any modification to any record in any batch is mathematically detectable without scanning all records.
Blocklog is not a logging tool.
Existing tools capture events. Blocklog creates evidence. These are fundamentally different things when a regulator is asking questions.
CloudWatch, Datadog, Splunk
Records what happened.
No integrity guarantee
Mutable, deletable
No chain of custody
Splunk SIEM, Microsoft Sentinel
Detects incidents.
Reactive, not preventive
Not evidence-grade
Not cryptographic
AI Compliance Infrastructure
Produces regulator-ready evidence.
Cryptographically sealed
SHA-256 + Merkle tree
Regulator-ready export
End-to-end traceability
Blocklog works alongside your existing logging infrastructure — it doesn't replace it.
Built for engineers.
Trusted by compliance.
Simple to integrate. Impossible to tamper with. The architecture is transparent, open-source verifiable, and designed for regulated environments.
Application
Your AI system
Any AI-powered application — credit scoring, chatbots, document processing, or decision engines.
Blocklog SDK
Python · TypeScript · REST
One import. Captures model version, prompt, output, latency, user context, and metadata automatically.
Immutable Audit Store
Hash-chained · Append-only
Every event is SHA-256 hashed and chained. No record can be modified or deleted without breaking the chain.
Verification Engine
Merkle Tree proofs
Merkle tree construction enables proof of any record without revealing others. Independent, open-source verification.
Evidence Package
PDF · JSON · CSV
Structured export containing all required documentation. Mapped to your specific regulatory requirements.
Regulator
RBI · SEBI · DPDP
Submit cryptographically verified evidence packages to RBI, SEBI, or any regulatory body within 24 hours of request.
Independent verification.
No trust required.
Every audit record Blocklog produces can be independently verified by any party — including regulators, auditors, or your own legal team — without accessing the Blocklog platform.
Open-source verification tool
Publish your verification CLI on GitHub — regulators can run it themselves.
No Blocklog account required
Verification works from the exported evidence package alone — no vendor dependency.
RFC 3161 trusted timestamps
Timestamps are sealed by a third-party TSA, not Blocklog. No clock manipulation possible.
