The main takeaway from the article: Brady plans every detail of his life so he can play football as long as possible, and he'll do anything he can to get an edge. He diets all year round, takes scheduled naps in the offseason, never misses a workout, eats what his teammates call "birdseed," and does cognitive exercises to keep his brain sharp. Brady struggles to unwind after games and practices. He's still processing, thinking about what's next.

Archived PDF from the original on 31 October Retrieved 30 October Federal Council Switzerland. Swiss Confederation. Archived PDF from the original on 5 December Retrieved 28 November Archived from the original on 1 January Bitcoin does not keep track of users; it keeps track of addresses where the money is.

Each address has two important pieces of cryptographic information, or keys: a public one and a private one. The public key, which is what the "bitcoin address" is created from, is similar to an email address; anyone can look it up and send bitcoins to it. The private address, or private key, is similar to an email password; only with it can the owner send bitcoins from it.

Because of this, it is very important that this private key is kept secret. To send bitcoins from an address, you prove to the network that you own the private key that belongs to the address, without revealing the private key. This is done with a branch of mathematics known as public-key cryptography. A public key is what determines the ownership of bitcoins, and is very similar to an ID number.

If someone wanted to send you bitcoins, all you would need to do is supply them your bitcoin address, which is a version of your public key that is easier to read and type. Anyone using the system can see how much money "ABC" has and how much money "DEF" has, but they cannot tell anything about who owns the address. But Bob and Alice each have a second key which only they individually know.

This is the private key, and it is the "other half" of a Bitcoin address. The private key is never shared, and allows the owner of the bitcoins to control them. However, if the private key is not kept secret, then anyone who sees it can also control and take the bitcoins there. The person who took it, told others about it later, saying "I'll send it back once Matt gives me a new address, since someone else can sweep [empty] out the old one.

Sites or users using the Bitcoin system are required to use a global database called blockchain. Blockchain is a record of all transactions that have taken place in the Bitcoin network. It also keeps track of new bitcoins as they are generated. With these two facts, the blockchain can keep track of who has how much money at all times. To generate a bitcoin, a miner must solve a math problem. However, the difficulty of the math problem depends on how many people are mining for bitcoin at the moment.

Because of how complicated the math problems usually are, they must be calculated with very powerful processors. The process of generating the bitcoins is called mining. Miners either compete with one another or work together in groups to solve a mathematical puzzle. The first miner or group of miners to solve the particular puzzle are rewarded with new bitcoins. The puzzle is determined by the transactions being sent at the time and the previous puzzle solution. This means the solution to one puzzle is always different from the puzzles before.

Attempting to change an earlier transaction, maybe to fake bitcoins being sent or change the number of someone's bitcoins, requires solving that puzzle again, which takes a lot of work, and also requires solving each of the following puzzles, which takes even more work. This means a bitcoin cheater needs to outpace all the other bitcoin miners to change the bitcoin history. This makes the bitcoin blockchain very safe to use. A popular image associated with Bitcoin is a QR code.

QR codes are a group of black and white boxes that are similar to barcodes. Barcodes are a row of lines, and QR codes are a grid of squares. Bitcoin uses QR codes because they can store more information in a small space, and a camera such as a smartphone can read them. The two QR codes on the Bitcoin note are the public and private addresses, and can be scanned with a number of online tools.

Everyone in the Bitcoin network is considered a peer, and all addresses are created equal. All transactions can take place solely from peer to peer, but a number of sites exist to make these transactions simpler. These sites are called exchanges.
