Blockchain is a specific type of database with special data organization and properties.
What is Blockchain? A blockchain is a distributed, immutable ledger that records transactions across a network of computers. Each participant maintains a complete copy of the ledger. Once data is written, it cannot be altered or deleted without the modification becoming immediately visible to the entire network. Unlike traditional databases managed by a single authority…
Centralized Exchanges (CEX) Centralized exchanges operate like traditional financial intermediaries. You deposit cryptocurrency into a wallet controlled by the exchange, which maintains an internal ledger tracking balances and executing trades against its order book. The exchange acts as the counterparty to every transaction. Advantages: Order execution speed measured in milliseconds Fiat on/off ramps (USD, EUR,…
The Impact of Blockchain and Crypto Technologies on Global Financial Markets Blockchain and cryptocurrency have moved beyond hype into practical application across financial systems. These technologies operate on fundamentally different principles than traditional finance—decentralized networks instead of centralized intermediaries—with real tradeoffs worth understanding. Think of blockchain as a distributed ledger where every participant holds an…
Querying transaction content from a blockchain network is essential for exploring blockchain history and verifying transaction details using a known transaction ID. In Hyperledger Fabric, you query transactions using the QSCC (Query System Chaincode), which handles ledger and Fabric-related queries. The GetTransactionByID function retrieves transaction details by ID. This guide assumes you have Hyperledger Fabric…
Setting Up Hyperledger Fabric 2.5+ on Ubuntu 24.04 LTS 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 provides an automated setup approach to get a working Fabric network…
