For the purposes of a thematic historical reference, most of the action supposedly takes place in Elba, New York. The city limit sign seen at the start of the film shows it has a population of 2,370, but the locations (such as a large shopping mall) are clearly in a much more populous town. Some identifiable settings are in more urbanized areas over 300 miles from the real Elba. It's acceptable for films to create a fictional version of a real town, but they should have changed the population sign to make it more consistent with the chosen locations. See more »
Comment puis-je stocker et a utiliser Bitcoins
Peer to peer (P2P) electronic cash is simply described as online money sent from one person to another without the need for a trusted third-party. As described in the original Bitcoin whitepaper by Satoshi Nakamoto, P2P cash makes use of digital signatures as part of the solution, but the main benefits are lost if a trusted third party is still required to prevent fraud. This makes P2P cash a trustless and safe way to transact without the need of intermediaries.
To keep the block generation time equal to ten minutes on average, both Bitcoin and Bitcoin Cash use an algorithm adjusting the mining difficulty parameter. This algorithm is called the difficulty adjustment algorithm (DAA). Originally, both Bitcoin and Bitcoin Cash used the same difficulty adjustment algorithm, adjusting the mining difficulty parameter every 2016 blocks. Since 1 August 2017, Bitcoin Cash also used an addition to the DAA, called an Emergency Difficulty Adjustment (EDA) algorithm. EDA was used alongside the original DAA and it was designed to decrease the mining difficulty of Bitcoin Cash by 20%, if the time difference between 6 successive blocks was greater than 12 hours.
