What is Blockchain? – Lower Level

Blocks of information are linked together using ‘hashes’ where each block references the previous block to form a chain

Block 124 Current Block #:00057erw54gfc7

Previous Block #:00045ftg87ahw9

Transaction: 00023caw84edh8

Block 126 Current Block #:00012raw89klj1

Previous Block #:00043fgl23chw8

Transaction: 00058dpe47ado5

Block 125 Current Block #:00043fgl23chw8

Previous Block #:00057erw54gfc7

Transaction: 00012sdg98lik4

These blocks are digitally signed and encrypted and make up the ‘ledger’

The ledger is replicated and distributed amongst the participants creating a ‘shared ledger’
