Assuming a 10-12 pound whole brisket and 1-1/2 hours of cooking time per pound as a guideline, calculate how long it will take to cook the brisket. For example, a 12 pound brisket will take approximately 18 hours to cook. Divide this time in half. The first time to turn the brisket is after 9 hours of cooking.
The blockchain is a distributed, public ledger that contains the history of every bitcoin transaction. Anyone can download a copy of the blockchain, and it can be inspected to trace the path of bitcoins from one bitcoin transaction to another. A Block refers to a set of Bitcoin transactions from a certain time period.
The blockchain is essentially a database running across a vast array of independent machines. With bitcoin, it oversees the exchange of money. But it can oversee the exchange of anything that holds value, including stocks, bonds, and futures as well as houses and car titles.
