Proposal: https://github.com/Mharris40/canton-dev-fund/blob/proposal-tokenproof/proposals/compliledger.md
Summary
CompliLedger is an AI-powered proof infrastructure platform that transforms requirements, targets, and context into deterministic decisions and independently verifiable proof.
Today, organizations repeatedly perform the same work.
They determine which requirements apply, gather evidence, evaluate controls, prepare reports, respond to audits, and demonstrate outcomes across internal controls, governance programs, contractual obligations, industry standards, regulatory frameworks, counterparties, and customers.
Much of this work is repeated because the underlying evidence, evaluations, and decisions are not portable.
The result is duplicated effort, fragmented processes, inconsistent audit evidence, and significant operational overhead.
CompliLedger automates this process through AI-driven deterministic reasoning.
The platform determines applicability, identifies the appropriate control set, orchestrates evidence collection, validates and normalizes evidence, evaluates controls, and produces deterministic decisions.
Those deterministic decisions become portable.
Portable decisions are transformed into standardized, machine-verifiable proof that can be independently verified and reused across organizations, frameworks, jurisdictions, and digital ecosystems.
The result is operational proof.
Proof enables verification.
Verification enables confidence.
Confidence is earned because proof exists.
CompliLedger is regulation agnostic. The architecture begins with requirements—not regulations—and supports internal controls, governance requirements, contractual obligations, asset registry controls, custodian controls, industry standards, and regulatory frameworks through a common deterministic reasoning and proof-generation architecture.
Rather than requiring every issuer, custodian, tokenization platform, transfer agent, settlement application, enterprise, or regulator to repeatedly perform the same reasoning and evaluation, CompliLedger enables organizations to reason once, generate proof once, verify independently, and reuse proof across multiple stakeholders and workflows.
This proposal focuses on production-hardening the CompliLedger proof infrastructure architecture for the Canton Network. The core architecture and proof-of-concept are already implemented and functioning on a local Canton ledger. Funding is requested to complete production hardening, ecosystem integration, SDK delivery, security review, and MainNet readiness rather than greenfield development.

Why Shared Ecosystem Infrastructure Matters
Today, every organization independently performs the same fundamental work.
They determine which requirements apply.
They identify applicable controls.
They collect evidence.
They evaluate controls.
They generate decisions.
They prepare audit artifacts.
They respond to regulators, auditors, customers, counterparties, and governance bodies.
Although these activities are repeated across organizations, the underlying reasoning process is largely the same.
As a result, organizations repeatedly build their own:
- applicability determination engines
- control evaluation logic
- evidence orchestration workflows
- evidence validation services
- proof generation capabilities
- verification mechanisms
This creates:
- duplicated engineering effort
- repeated evidence collection
- fragmented verification practices
- inconsistent audit evidence
- higher implementation costs
- operational overhead
- reduced interoperability between organizations
CompliLedger standardizes these capabilities through a reusable proof infrastructure architecture.
Rather than repeatedly performing the same reasoning and evaluation, organizations can automate deterministic reasoning, generate reusable proof, and enable independent verification through a common platform.
The result is:
- automated deterministic reasoning
- reusable machine-verifiable proof
- elimination of redundant evidence collection
- independent verification by multiple stakeholders
- accelerated audits, regulatory reviews, and business workflows
- proof portability across organizations, frameworks, and jurisdictions
- reusable, composable proof that can support multiple assurance processes
Instead of every participant independently building evidence pipelines, evaluation engines, proof generation, and verification infrastructure, the Canton ecosystem gains a shared foundation for transforming requirements, controls, and evidence into deterministic decisions and independently verifiable proof.
As adoption grows, proof becomes reusable rather than repeatedly regenerated, enabling organizations to reason once, generate proof once, verify independently, and reuse that proof across multiple stakeholders, workflows, and digital ecosystems.
Current Status
The core CompliLedger platform has already been designed and implemented.
CompliLedger currently provides AI-driven deterministic reasoning, applicability evaluation, evidence orchestration, control evaluation, deterministic decision generation, and proof generation as a functioning platform.
This proposal funds the implementation, production hardening, and production deployment of the Canton-native architecture.
The work includes implementing the reusable Canton proof infrastructure, DAML components, workflow integration, developer SDKs, ecosystem validation, and MainNet deployment.
The objective is not to invent the CompliLedger platform, but to deliver its complete Canton-native implementation and establish reusable proof infrastructure for the Canton ecosystem.
The current implementation already demonstrates the complete deterministic reasoning and proof pipeline, including:
- AI-driven deterministic reasoning
- Applicability evaluation
- Machine-readable control execution
- Evidence orchestration and collection
- Evidence validation and normalization
- Canonical Evidence Package generation
- Evidence sufficiency assessment
- Deterministic control evaluation
- Deterministic decision generation
- Portable Decision Package generation
- Canonical Proof Package generation
- Canonical Proof Hash generation
- Proof lifecycle management
- ComplianceProof
- ComplianceGuard
- EvaluationRequest
- Proof-gated workflow execution
- Atomic DvP workflows
- Canton Ledger API integration
- Independent proof verification
- CI-validated DAML packages
The remaining work focuses on production hardening, ecosystem integration, developer tooling, security review, operational readiness, and MainNet deployment rather than inventing a new architecture.
The objective is to transform an already functioning deterministic reasoning and proof infrastructure into reusable ecosystem infrastructure that other Canton participants can adopt without rebuilding these capabilities independently.
CI Evidence
The current CompliLedger implementation is continuously validated through automated build and test pipelines.
Every change is automatically compiled, tested, and verified before being merged, ensuring the deterministic reasoning engine, proof infrastructure, and reference implementations remain operational throughout development.
dpm build --all and dpm test successfully complete on every push.
Package Status
| Package | Purpose | dpm build | dpm test |
|---|---|---|---|
| daml/ | Core proof infrastructure primitives (ComplianceProof, ComplianceGuard, EvaluationRequest) | ✓ Pass | ✓ Pass |
| examples/cip0056-gated-transfer/ | Reference implementation demonstrating proof-gated token transfer and workflow integration | ✓ Pass | ✓ Pass |
| examples/stablecoin-genius-act/ | Reference implementation demonstrating deterministic evaluation and proof generation using a regulatory control set | ✓ Pass | ✓ Pass |
The continuous integration pipeline validates that the core reasoning architecture, proof lifecycle, workflow integration patterns, and reference implementations remain stable and reproducible throughout development.
This provides confidence that the proposal builds upon a functioning implementation rather than a conceptual design.
Current Test Coverage
The current implementation validates the end-to-end deterministic reasoning and proof lifecycle through automated integration tests.
Existing test coverage demonstrates the core architectural capabilities of CompliLedger, including:
✔ Proof lifecycle management
✔ Deterministic control evaluation
✔ Proof-gated workflow execution
✔ Atomic multi-party DvP execution
✔ Independent proof verification
✔ End-to-end Canton workflow integration
Verified Behaviors
- Deterministic reasoning produces reproducible decisions from identical inputs
- Proof lifecycle transitions (Active → Suspended → Revoked) function correctly
- Proof-gated workflow execution succeeds only when required proof conditions are satisfied
- Atomic DvP workflows execute within a single Canton transaction boundary
- Canonical proof hashes can be independently recomputed and verified
- Proof records are retrieved and validated through the Active Contract Service (ACS)
- Multi-party visibility and observer permissions function according to the Canton privacy model
- End-to-end reasoning, proof generation, and verification complete successfully on a local Canton ledger
These tests demonstrate that the core deterministic reasoning engine, proof infrastructure, and workflow integration patterns are already operational. The remaining work focuses on production hardening, scalability, ecosystem integration, and MainNet readiness rather than proving the underlying architecture.
Problem This Solves
Organizations continuously make decisions.
Every decision begins with requirements.
Those requirements may originate from:
- internal controls
- governance policies
- contractual obligations
- asset registry requirements
- custodian requirements
- industry standards
- regulatory frameworks
Before any organization can act, it must repeatedly answer the same questions:
- What requirements apply?
- Which controls must be evaluated?
- What evidence is required?
- Is the evidence sufficient?
- What decision should be made?
Today, those questions are answered independently by every organization, often multiple times for the same evidence.
Evidence remains fragmented across:
- PDFs
- spreadsheets
- reports
- attestations
- APIs
- databases
- emails
- workflow-specific systems
As a result, organizations repeatedly perform the same reasoning, collect the same evidence, evaluate the same controls, and generate the same conclusions for different auditors, regulators, counterparties, customers, and governance processes.
This creates:
- duplicated deterministic reasoning
- redundant evidence collection
- fragmented verification practices
- inconsistent audit evidence
- repeated control evaluations
- operational overhead
- higher implementation costs
- reduced interoperability
CompliLedger standardizes this process through AI-driven deterministic reasoning and reusable proof infrastructure.
The platform continuously determines applicability, orchestrates evidence collection, evaluates controls, generates deterministic decisions, transforms those decisions into portable decision packages, and produces independently verifiable proof.
Rather than requiring every participant to repeatedly perform the same reasoning and evaluation, CompliLedger enables organizations to:
- reason once
- generate proof once
- verify independently
- reuse proof across organizations, frameworks, jurisdictions, and digital ecosystems
The result is operational proof that accelerates audits, regulatory reviews, governance processes, business workflows, and digital asset operations while reducing repeated effort across the ecosystem.
Why Now
Digital systems are becoming increasingly autonomous, interconnected, and machine-driven.
Organizations are no longer managing a single audit or a single regulatory framework. They are simultaneously operating across internal controls, governance programs, contractual obligations, industry standards, regulatory frameworks, counterparties, and digital ecosystems.
As these environments become more complex, organizations are repeatedly performing the same deterministic reasoning:
- determining what requirements apply
- identifying the correct controls
- gathering evidence
- evaluating controls
- generating decisions
- demonstrating outcomes
Most of these activities remain manual, fragmented, and organization-specific.
The result is duplicated effort, repeated evidence collection, inconsistent evaluations, and operational overhead that grows as organizations adopt additional systems, partners, and regulatory obligations.
The next generation of enterprise infrastructure is not simply about automating workflows.
It is about automating deterministic reasoning and transforming those decisions into reusable, independently verifiable proof.
CompliLedger enables this transition.
By combining AI-driven deterministic reasoning with proof infrastructure, organizations can continuously evaluate requirements, generate portable decisions, produce machine-verifiable proof, and reuse that proof across organizations, frameworks, jurisdictions, and digital ecosystems.
For the Canton ecosystem, this provides an opportunity to establish a shared proof infrastructure layer that applications, issuers, custodians, tokenization platforms, settlement workflows, and future ecosystem participants can consume rather than independently rebuilding the same reasoning, evaluation, and verification capabilities.
Core Platform Services
CompliLedger is built around a set of reusable platform services that collectively automate deterministic reasoning, generate portable decisions, and produce independently verifiable proof.
Deterministic Reasoning Engine
The Deterministic Reasoning Engine continuously transforms requirements, targets, and context into deterministic decisions.
Core capabilities include:
- applicability evaluation
- control determination
- evidence orchestration
- evidence validation
- evidence normalization
- evidence sufficiency assessment
- control evaluation
- deterministic decision generation
Identical inputs always produce identical decisions.
Portable Decision Service
Every deterministic decision is transformed into a Portable Decision Package.
The package contains the information necessary for downstream systems to consume, share, and reason about a decision without repeating the underlying evaluation.
Decision portability enables reuse across organizations, workflows, frameworks, and jurisdictions.
Proof Infrastructure
Portable Decision Packages are transformed into machine-verifiable proof through the CompliLedger proof infrastructure.
Core capabilities include:
- Canonical Proof Package generation
- Canonical Proof Hash generation
- Anchor Payload generation
- immutable proof anchoring
- proof lifecycle management
- independent proof verification
ComplianceGuard
ComplianceGuard provides a reusable interface allowing Canton applications and workflows to consume independently verifiable proof during execution.
Rather than embedding evaluation logic into every application, workflows can consume standardized proof through a common interface.
EvaluationRequest
EvaluationRequest provides a composable workflow for requesting, resolving, and tracking deterministic evaluations across distributed systems.
Independent Proof Verification
Proof artifacts can be independently verified through deterministic proof hash recomputation and Canonical Proof Package validation.
Authorized stakeholders can verify the integrity of a decision without repeating the underlying reasoning process.
Privacy-Preserving Visibility
CompliLedger leverages Canton's privacy model to ensure proof records, evidence references, and verification artifacts are visible only to authorized participants.
This enables independent verification while preserving confidentiality.
Proof-Gated Workflow Execution
Applications can consume proof directly within business workflows.
Issuance, transfer, settlement, governance, operational, and other workflows can require valid proof before execution, enabling deterministic, machine-verifiable decision enforcement across the Canton ecosystem.
Why Canton
CompliLedger is designed to automate deterministic reasoning, generate portable decisions, and produce independently verifiable proof.
For many enterprise workflows, these capabilities require more than a traditional blockchain.
They require coordinated execution, privacy, and deterministic multi-party workflows.
Canton provides three foundational capabilities that make it particularly well suited for proof infrastructure:
Atomic Multi-Party Execution
Deterministic decisions, proof generation, and business workflows can execute within a single coordinated transaction.
This enables applications to consume proof directly during issuance, settlement, governance, redemption, and other operational workflows without introducing race conditions between evaluation and execution.
Privacy-Preserving Visibility
Proof records, evidence references, and verification artifacts are visible only to authorized participants.
Organizations can independently verify outcomes while preserving confidentiality and protecting sensitive operational data.
Deterministic Workflow Coordination
Canton's authorization model and synchronized multi-party execution ensure that identical inputs produce identical workflow outcomes.
This aligns naturally with CompliLedger's deterministic reasoning architecture and enables independently verifiable proof that can be trusted across multiple participants.
Together, these capabilities allow deterministic reasoning, portable decisions, proof generation, independent verification, and workflow execution to operate as a single coordinated system.
Rather than functioning as a standalone reporting platform, CompliLedger becomes shared proof infrastructure that applications, issuers, custodians, asset registries, settlement workflows, and future ecosystem participants can consume directly through the Canton Network.
Alignment with Approved Dev Fund Investments
CompliLedger complements previous Development Fund investments by introducing the deterministic reasoning and proof infrastructure layer that enables applications to generate, consume, and independently verify portable proof across the Canton ecosystem.
Rather than replacing existing protocol, token, or tooling investments, CompliLedger builds upon them by providing a reusable application-layer architecture for deterministic reasoning, portable decisions, and machine-verifiable proof.
