What is blockchain
A blockchain stands as a distinctive variant of distributed ledger technology (DLT), offering a secure environment for transactions among participating stakeholders. It manifests as a decentralised database, overseen collectively by computer nodes interconnected through a peer-to-peer network. Within this innovative framework, the blockchain meticulously eradicates any single point of harm, upholding a fixed and incorruptible ledger of every transaction.
The foundation of a blockchain comprises individual blocks, each serving as a self-contained repository of transactional data. These blocks are methodically organised in chronological order and interconnected via robust hash functions. This hashing mechanism provides intimidating resistance against alterations to a block’s data once it has become a part of the chain. This feature amalgamation culminates in a highly secure and transparent system.
