I want to demonstrate provable data consistency across a geographically distributed Hyperledger Fabric network by persisting the blockchain ledger in CockroachDB instead of the default back-end. The work centres on two Fabric layers: chaincode and the ledger itself. Chaincode reads and writes must be routed so that every block committed by a peer is durably stored in CockroachDB, and peers must replay that data with no divergence even under node failure or network partitions. The scope includes mapping Fabric’s block and state data structures to a CockroachDB schema, wiring the peer so that commit and endorsement steps call the database seamlessly, and validating the design with a small multi-region testnet. CockroachDB will act strictly as the ledger store; MSP and other ser...

...immutably stores and certifies every step on Hyperledger Fabric. The objective is clear: the moment a potential claim is flagged in the BIM environment, it should be automatically registered, classified, validated against the relevant FIDIC clauses, and published to an auditable ledger—with a web dashboard showing the entire trail in real time. Scope of work • BIM connector: a service that extracts the necessary objects, properties, and metadata directly from Revit (IFC compatibility is a plus) and hands them to the API. • Integration backend (API): a lightweight, well-documented REST/GraphQL layer focused on automated workflows—no manual triggers. It orchestrates data flow, handles authentication, and forwards transactions to the chaincode. • ...

Building a transparency-first supply-chain network on Hyperledger Fabric. The network must capture every inventory hand-off, trigger smart-contract events automatically, and keep supplier credentials verifiable at any moment. The work centers on: • Configuring a permissioned Fabric network (ordering service, peers, CAs). • Writing chaincode that covers inventory tracking logic, granular smart-contract rules, and supplier verification workflows. • Issuing “blockpassports” as on-chain NFTs so each batch or asset carries a tamper-proof identity that follows it through the chain. • Exposing REST or gRPC endpoints so my existing ERP can push and pull data without friction. • Packaging the setup (docker compose / Kubernetes scripts and conci...

...baked into the dataset pipeline: the IDS must correctly classify Malware, Phishing, and DDoS patterns. Synthetic generation for edge cases is fine as long as the final validation shows clear detection rates for all three. • Smart-contract aggregator: the chain’s sole responsibility is aggregating model weights. I want a concise contract—Solidity for an Ethereum PoA test-network or chaincode for Hyperledger Fabric—that stores submissions, computes the federated average, and emits the new global state. No on-chain data other than floats and a small hash for versioning. • bridge: a lightweight Python client that listens for the latest global weights, injects them back into the local model, and kicks off the next training epoch. Acceptance will be base...

Digital Chain of Custody for Forensic Evidence ​Concept: A system for police and legal teams to track digital evidence (logs, hard drive images, CCTV footage) without tampering. ​The Problem: In court...with after seizure. ​The Solution: When evidence is collected, a cryptographic hash (SHA-256) of the file is generated and stored on a Blockchain. Every time the evidence is "checked out" or viewed by an officer, a transaction is recorded. If the file hash changes even by one bit, the Blockchain rejects it. ​Tech Stack: ​Frontend: React.js or Flutter. ​Blockchain: Ethereum (Sepolia Testnet) or Hyperledger Fabric (for private permissioned access). ​Storage: IPFS (InterPlanetary File System) to store the actual large files; Blockchain only stores the hash. ​Smart Contracts: S...

I need a full-stack solution that turns raw Revit project data into verifiable FIDIC-compliant construction claims, stored immutably on Hyperledger Fabric and surfaced through a clean web dashboard. The workflow I have in mind is straightforward: Revit models (or their IFC/CSV exports) are pushed to a REST API you build in Node.js or Python. Your parser extracts the quantities and events that matter, the rule engine interprets them under the FIDIC Red Book, and the resulting claim package is written to a Fabric network. Every supporting document or 3D fragment is fingerprinted, with the hash anchored on-chain and the file itself held on IPFS or another secure store. The same API must expose three core functions—claim management, user authentication and data analytics&mda...

Think Solidity (ERC-721 or ERC-1155 with OpenZeppelin), IPFS or Arweave for storage, plus a Python or Node script that calls GPT-4 / Llama via LangChain or similar. This person must also be familiar with setting up a blockchain and wallets. Specifically using AWS to start, but flexible on learing. Deliverables • Hyperledger smart contract with ownership, transferability, and royalty logic ready for main-net deployment • Data ingestion script that uploads assets, builds metadata, and calls the contract’s mint() function • LLM integration code that analyses each asset bundle and appends the AI-generated output to the metadata • Simple demo (CLI or lightweight web pa...

I am implementing a hybrid system that couples Hyperledger Fabric with secure off-chain storage to manage forensic evidence from computers, mobile phones, and CCTV cameras. The goal is to register every piece of digital evidence, preserve its integrity with SHA-256 hashes, and maintain an immutable, legally admissible chain-of-custody log. Scope of work You will extend or build the Hyperledger Fabric network, write the required chaincode, and wire it to Google Cloud Storage where the large raw files live. The ledger itself will only hold metadata—device identifier, location of collection, collector information—along with the hash and timestamp, while the files remain safely off-chain. Key tasks • Design the data model for the evidence metadata and create th...
