In February 2019, Coinbase announced that it had acquired "blockchain intelligence platform" Neutrino, an Italy-based startup, for an undisclosed price. The acquisition raised concern among some Coinbase users based on Neutrino founders' connection to the Hacking Team, which has been accused of providing internet surveillance technology to governments with poor human rights records. On March 4, 2019, Coinbase CEO Brian Armstrong said his company "did not properly evaluate" the deal from a due diligence perspective and thus any Neutrino staff who previously worked at Hacking Team "will transition out of Coinbase."
In the case of Bitcoin, miners run computer programs to verify the data that creates a complete transaction history of all Bitcoin. A technology known as the blockchain, which is used to create irreversible and traceable transactions, makes the process of verification possible. Once a miner has verified the data (which comes in a block, hence, blockchain), they are rewarded with some amount of digital currency, the same currency for which they were verifying the transaction history. So mining Bitcoin, for example, would earn you Bitcoin.
