— In a 1,500-word memo obtained by The New York Times over the weekend, the company’s top lobbyist, Nick Clegg, sought to rebut Haugen’s allegations ahead of her unveiling in an episode of “60 Minutes” on Sunday night. “Social media has had a big impact on society in recent years, and Facebook is often a place where much of this debate plays out,” he said in the memo, in which he called Haugen’s impending accusations, which included blaming Facebook for January’s insurrection at the Capitol, “misleading.” He wrote that “what evidence there is simply does not support the idea that Facebook, or social media more generally, is the primary cause of polarization.”
The next phase in the crypto mining process is to compile a list of all transactions, which is subsequently included in a new unconfirmed data block. It avoids “double spending” of any cryptocurrency and keeps a permanent and public record by adding their transaction to the blockchain, once the verification procedure is complete. The record is immutable, which means it can never be changed or corrupted.

Virtual currencies. Like fiat currency, virtual currencies such as Bitcoin, Litecoin, and Ether are intended as a medium of exchange that enables two parties to transact business. But there are important differences: No physical coins or bills. Virtual currencies exist only in computer code. Except for visual representation of Bitcoin and altcoins in advertising and displays, and coin-like tokens that may be produced for marketing purposes, there are no actual coins or bills. Not legal tender. Virtual currencies are not legal tender and are not issued or backed by a government. However, many virtual currencies, which are called convertible virtual currencies, can be redeemed for fiat currency on a number of exchanges. No regulation. Virtual currencies are not regulated by any government agency or authority. However, regulation is being considered, especially where virtual currencies function as securities when they’re used to raise capital and when traded on exchanges.
