Bitcoin is a digital asset and a payment system invented by Satoshi Nakamoto. Transactions are verified by network nodes through cryptography and recorded in a public dispersed ledger called a blockchain. Bitcoin is unique in that there are a finite number of them: 21 million.
Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies, products, and services. As of February 2015, over 100,000 merchants and vendors accepted bitcoin as payment.
What is Ethereum?
Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of fraud or third party interference.
Ethereum is powered by the Ethereum blockchain. Ether is a cryptocurrency whose blockchain is generated by the Ethereum platform.
What is a Cryptocurrency?
A 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.
What is a 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 differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
What is Mining?
Mining is how new Bitcoin and Ethereum are created. Miners are rewarded with cryptocurrency for verifying and committing transactions to the blockchain. Ethereum miners are rewarded based on their share of work done, rather than their share of the total number of blocks mined.
