What is Blockchain?
A blockchain is a digital ledger of all cryptocurrency transactions. It is constantly growing as “completed” blocks are added to it with a new set of recordings. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
What is Cryptocurrency?
Cryptocurrency is a digital or virtual currency that uses cryptography to secure its transactions and to control the creation of new units. Cryptocurrencies are decentralized, meaning they are not subject to government or financial institution control. Bitcoin, the first and most well-known cryptocurrency, was created in 2009.
How do Blockchain and Cryptocurrency Work?
Blockchain is a decentralized database that stores information about cryptocurrency transactions. Cryptocurrency is a digital or virtual currency that uses cryptography to secure its transactions and to control the creation of new units.
