Verifiable Data Provenance for RWA & regulated data
DataMgmt Node gives the data behind tokenized real-world assets and regulated workflows an immutable, independently verifiable audit trail — combining EVM blockchains, a Kademlia DHT, and end-to-end encryption so you can share sensitive data and prove who touched it and that it was never altered.
pip install datamgmtnode What is DataMgmt Node?
Decentralized data sharing, with compliance built in.
DataMgmt Node is an open-source (MIT) platform that lets organizations share data without a centralized server. Storage is distributed peer-to-peer over a Kademlia DHT, data is protected with end-to-end Fernet encryption, and every sharing operation is recorded on an EVM-compatible blockchain as an immutable audit trail — so GDPR, HIPAA and SOX evidence is verifiable rather than trusted.
Built-in ERC-20 token support turns proprietary datasets into pay-per-access products. You self-host the node, keep your keys, and connect to Ethereum, Polygon, Arbitrum, Optimism or any EVM chain.
- Data sovereignty. Self-hosted P2P storage removes the single cloud provider you have to trust.
- Provable compliance. Immutable, on-chain audit trails for GDPR, HIPAA and SOX.
- Data monetization. ERC-20 token payments enable pay-per-access to proprietary datasets.
The problem with centralized data
- Audit logs are owned by one party — who can edit them
- A tokenized asset is only as trustworthy as its unprovable backing data
- Compliance evidence requires trusting a third party’s records
The DataMgmt Node solution
- P2P distribution ensures data availability across nodes
- Self-hosted nodes give you complete data sovereignty
- Blockchain-backed audit trails are immutable and verifiable
In practice
From install to an audited data share.
Three commands to a running node, one API call to share encrypted data with an on-chain compliance record.
# install, initialise on a testnet, and start the node
$ pip install datamgmtnode
$ datamgmtnode init --network sepolia
$ datamgmtnode start
→ internal API http://localhost:8080
→ external API http://0.0.0.0:8081
→ dashboard http://localhost:8082# share encrypted data — recorded on-chain for audit
$ curl -X POST http://localhost:8081/share_data \
-F recipient=0x8a3f… \
-F 'file=@patient-record.json'
{
"hash": "Qm9f…c2",
"tx": "0x71b…e4", // compliance record
"status": "shared"

Features
Enterprise-grade, from the ground up.
Security, compliance and scalability as platform primitives — not add-ons.
Blockchain compliance
Every share is recorded on an EVM chain as a zero-address transaction with encoded event data — immutable audit trails for GDPR, HIPAA and SOX.
Learn more →P2P network
A Kademlia DHT distributes data across 10,000+ nodes with O(log n) lookups, automatic peer discovery and health monitoring.
Learn more →End-to-end encryption
Fernet (AES-128-CBC) with PBKDF2 key derivation at 480,000 iterations, versioned key rotation and RSA-PSS node authentication.
Learn more →Compliance & audit
Verify any shared record against the chain with GET /verify_data. Compliance evidence is provable, not just logged.
Learn more →Token payments
Native and ERC-20 token support for pay-per-access data models — transfer, check balances and gate access to datasets.
Learn more →Three RESTful APIs
Internal (8080), External (8081) and Dashboard (8082 + WebSocket) APIs with token-bucket rate limiting and validation.
Learn more →How it works
Four layers, one data share.
A request is encrypted, distributed across the P2P network, and recorded on-chain for compliance — in one operation.
