Blockchain – Crypto Glossary Definition:
A blockchain is a foundational technology that underpins the operation of nearly all cryptocurrencies and has applications across various industries. At its core, a blockchain is a distributed and decentralized digital ledger, characterized by its tamper-evident and tamper-resistant properties. It provides a secure and transparent way to record and verify transactions within a network of participants.
The essence of blockchain technology lies in its ability to enable users to record transactions in a shared ledger that is distributed across multiple nodes in the network. Once a transaction is added to the ledger and consensus is reached among the network’s nodes regarding its validity, it is cryptographically locked into a “block” and officially recorded. This “block” serves as the foundation for the subsequent one, creating a continuous and chronological chain of interconnected blocks, thus the name “blockchain.”
