Blockchain is a distributed digital ledger that records transactions across a network of computers (nodes). Each block contains transaction data and links to the previous block, creating an unchangeable chain.

Blockchain technology makes digital assets truly unique and verifiably owned by specific people – solving the problem of how to prove who owns what in the digital world. Blockchain powers cryptocurrencies like Bitcoin, but it’s also revolutionising supply chains, legal contracts, and identity verification by creating unbreakable trails of information.
