If grey line less than blue line, The generation time is decreasing. This property is crucial to the proof of work algorithm involved in mining: to successfully solve a block, miners try to combine all of the inputs with their own arbitrary piece of input data in such a way that the resulting hash starts with. You can experiment with hash values using Python, a programming language installed on Mac and Linux operating systems by default. Mark Karpelès, head of Mt Gox, went on trial in Japan in July, facing up to five years in jail under charges of embezzlement and the lost of 28m of user funds. Grey line Average block generation time of 1008 blocks.
In 2001, SHA-256 was developed by the National Security Agency (NSA) in the USA. Bitcoin s proof of work algorithm is based on SHA-256. Using this, Bitcoin miners solve computationally difficult math problems to add blocks into the blockchain.

Bitcoin is going to crash
After 2016 blocks generated, Bitcoin will adjust difficulty to estimated difficulty in order to keep the block generation time at 600 seconds. The marketplace suspended operations on Thursday while it investigated the breach, saying it was working with law enforcement as a matter of urgency while urging users to change their passwords. Its the need for this large amount of processing power that means new bitcoins get mined over a long period of time, not all at once. A hash algorithm takes data of any arbitrary size (numbers, alphabets, media files) and transforms it into a fixed alphanumeric string. This means that if a hacker is able to access the database containing the stored hashes, they will not be able to immediately compromise all user accounts because there is no easy way to find the password which produced any given hash. The price of bitcoin has surged to more than 14,668, gaining around 2,000 (1,494) of value in a day according to bitcoin monitor CoinDesk. Let see how a miner wins the lottery. In bitcoin mining, the inputs for the function are all of the most recent, not-yet-confirmed transactions (along with some additional inputs relating to the timestamp and a reference to the previous block).
