+ +Copy these snippets to integrate DataMgmt Node in your application
+{pythonCode}
+ {jsCode}
+ {curlCode}
+ + Every data sharing operation is cryptographically recorded on blockchain, creating immutable audit trails that satisfy GDPR, HIPAA, SOX, and other regulatory requirements. +
++ DataMgmt Node records every data operation as a blockchain transaction, creating tamper-proof evidence for regulatory audits. +
+ +When data is shared, accessed, or modified, the node captures the operation details including timestamp, parties, and data hash.
+The operation is encoded as a compliance event with cryptographic signatures, ensuring authenticity and integrity.
+The event is submitted to the configured EVM blockchain as a transaction to the zero address, permanently recording the operation.
+Anyone can verify the operation occurred by checking the blockchain transaction, providing independent third-party proof.
+{complianceCode}
+ + DataMgmt Node supports any EVM-compatible blockchain. Configure your preferred network based on cost, speed, and decentralization requirements. +
+ +Maximum decentralization and security. Best for high-value compliance records.
+Low transaction costs with fast finality. Ideal for high-volume operations.
+Ethereum security with L2 efficiency. Great balance of cost and security.
+Fast transactions with Ethereum security. Optimistic rollup technology.
+Deploy on any EVM-compatible chain including private enterprise networks, Avalanche, BSC, or custom rollups. Simply configure the RPC endpoint.
+{configCode}
+ + Blockchain audit trails provide verifiable proof for multiple compliance frameworks. +

+ ++ Meet regulatory requirements with immutable blockchain audit trails. Every data sharing operation is cryptographically recorded, providing verifiable proof for GDPR, HIPAA, SOX, and other compliance frameworks. +
++ Traditional audit logs can be modified, deleted, or corrupted. Database administrators can alter records. Backup systems can fail. These vulnerabilities create compliance risk and auditor skepticism. +
++ Blockchain audit trails solve this by recording every data operation as an immutable transaction on a decentralized network. Once recorded, the audit trail cannot be modified by anyone, including system administrators. +

++ DataMgmt Node uses Kademlia Distributed Hash Table (DHT) for efficient peer discovery and data routing across thousands of nodes with O(log n) lookup efficiency. +
++ Kademlia is a distributed hash table (DHT) protocol designed for decentralized peer-to-peer networks. It uses XOR-based distance metrics to organize nodes and route queries efficiently across the network. +
++ Unlike traditional client-server architectures, Kademlia enables nodes to find data and peers without central coordination. Each node maintains a routing table with contacts organized by their distance in the 160-bit address space. +
++ DataMgmt Node implements a production-ready Kademlia DHT with extensions for: +
+Nodes join the network by contacting bootstrap nodes and populating their routing tables
+Queries route through progressively closer nodes using XOR distance metrics
+Data is stored on nodes closest to the data's hash for efficient retrieval
+Continuous peer health checks ensure routing tables stay current
+{networkCode}
+ + Kademlia DHT supports four fundamental operations that enable decentralized data management. +
+ +PING
+ + Check if a node is online and responsive. Used for health monitoring and routing table maintenance. +
+GET /network/ping/{"{node_id}"}
+ STORE
+ + Store a key-value pair on nodes closest to the key's hash. Data is replicated across multiple nodes for redundancy. +
+POST /network/store+
FIND_NODE
+ + Locate nodes closest to a given ID. Returns k-closest nodes from the recipient's routing table. +
+GET /network/find/{"{node_id}"}
+ FIND_VALUE
