In distributed systems like blockchains, consensus is the mechanism by which all nodes agree on a single version of the ledger state. Without it, a decentralized network falls apart—you’d have conflicting transaction histories, double-spending, and no way to determine which version is authoritative. Consensus algorithms solve this by providing cryptographic or economic guarantees that make…
Querying transaction details from a Hyperledger Fabric ledger is critical for auditing, compliance verification, and debugging chaincode behavior. The QSCC (Query System Chaincode) provides the GetTransactionByID function to retrieve complete transaction metadata including endorsements, read/write sets, and validation status. This guide uses Hyperledger Fabric 2.5+ on Ubuntu 24.04 LTS with the test-network from fabric-samples. Environment…
Hyperledger Fabric is a modular, enterprise-grade consortium blockchain platform. While its official documentation is comprehensive, deploying a test network from scratch requires configuring multiple dependencies and tools—a process that’s time-consuming for new users. This guide covers both automated and manual setup approaches to get a working Fabric network running quickly. Prerequisites You’ll need: Ubuntu 24.04…
When you need a specific Go version on Ubuntu, the default package manager often lags behind. Production systems like Kubernetes, Hyperledger Fabric, and other projects frequently require versions newer than what’s available in standard repositories. This guide covers system-level installation that allows multiple versions to coexist. Remove existing Go installations Start by cleaning up any…
