What is blockchain? | DEFINE

Blockchain is a database of ledgers, or
blocks, spread across multiple computers. Each block contains a set of codes
called hashes, which keep the blocks in sync. Every time a new entry is introduced, a new hash is created. Once it is verified,
the new entry is accepted by all computers. This network of ledgers is
what makes blockchain secure. Tampering with just one block, or one computer, has
no effect. For perspectives on this topic, click the links provided.
