Hash Chain Python Packages

tamga-protocol

Encrypted, portable, tamper-evident agent state — identity + memory + verifiable work receipts that survive the host. WASI 0.3, default-deny, simnet. PyPI: tamga-protocol

homestead-ledger

Append-only household ledger with hash-chain provenance.

nomosguard

Deterministic security reasoning core: hash-chained evidence ledger, attack-path rule engine, fail-closed policy gate. LLMs produce evidence and explain decisions; they never cross the decision boundary.

qp-capsule

The open protocol for cryptographically sealed audit records of autonomous AI operations. SHA3-256 + Ed25519 + hash chain. Spec, conformance suite, and reference implementations in Python and TypeScript.

tersign

Python SDK for Tersign, the evidence layer for the agent economy — offline verification of counter-signed receipts, hash chains, chain commitments and frozen evidence bundles. Zero dependencies, standard library only. PyPI: tersign

revoco

Undo for AI agent actions. Plans the rollback before the action runs, proves it still works, and rolls back a compromised grant's whole blast radius in one call.

provenrail

Guardrails for AI agents, with a receipt. Blocks destructive tool calls before they run and signs every decision into a hash-chained record anyone can verify with an open-source tool.

sealstack

Signed, hash-chained action records for AI agents, receipts counter-signed by the receiving service, an offline verifier (exit 0/1/2), exports to AERF, Agent Receipts and noa. Python SDK + receipt spec.

tamper-signal

Tamper Signal: signed receipts for vibe-coded data pipelines. Proves nobody changed your data, and shows the exact link if they did.

szl-energy-attest

Attestable energy receipts for governed compute — MEASURED-NVML joules (or honest UNAVAILABLE null), cheapest-watt placement, hash-chained signable receipts. Vendors szl_energy_core. Λ = Conjecture 1 (advisory) · never fabricates a joule · Mirrors HF SZLHOLDINGS/szl-energy-attest · Apache-2.0.

ai-audit-trail

Cryptographically verifiable audit trail for AI systems — Ed25519 signed, hash-chained Decision Receipts with ISO 42001 / NIST AI RMF compliance. No blockchain, no SaaS.

nobulex

Reproducible research on verification boundaries, plus the earlier Nobulex receipt prototype. Current financial decision-integrity gateway: github.com/arian-gogani/nobulex-registry.

auditchain

Tamper-evident, hash-chained audit logging for Python. Async-first, zero runtime dependencies.

computeledger-cli

CLI, library, and MCP server for signing, hash-chaining, and verifying compute usage receipts across any provider.

swarm-at-sdk

Public settlement ledger for swarm.at — 901 hash-chained entries, 76 types

aiauditlog

Open-source, vendor-neutral toolkit for creating, storing, querying, and verifying privacy-aware, tamper-evident audit logs for AI models, agents, tools, policy decisions, human reviews, and workflow outcomes.

phb-agentledger

A tamper-evident, hash-chained audit ledger for AI agent actions. Edit any stored record and verify_chain() says so.

behavry-verify

Independently verify Behavry APR evidence packages offline — hash chain and signature, with no Behavry account, database or network.

attestroot

Append-only, hash-chained evidence log for AI agents — tamper-evident audit trail with RFC 6962 Merkle checkpoints and deterministic replay. Pure stdlib, zero dependencies.

chain-of-consciousness

Cryptographic provenance protocol for autonomous AI agents — tamper-evident hash chains with Bitcoin OpenTimestamps anchoring. Part of the Agent Trust Stack.

dcl-core

Tamper-evident record chain and multi-party consensus primitives for AI agent audit systems

incident-ledger

Append-only, hash-chained evidence log for AI agents — tamper-evident audit trail with RFC 6962 Merkle checkpoints and deterministic replay. Pure stdlib, zero dependencies.

provenance-substrate

The model proposes, deterministic code disposes, a human signs. Content-addressed envelopes, hash-chained audit, signed approval — for ledgers, Lean proofs, manuscript claims, reproductions, benchmarks, peer review. Conformance-tested; byte-compatible with @kernel.chat/kbot-finance.

daryl-dsm

Off-chain append-only, hash-chained, tamper-evident audit layer for AI agents
