| Bitcoin Mining |
Mining is a record keeping service done through the use of computer process power. Miners keep the block chain consistent,complete and unalterable by repeatedly verifying and collecting newly broadcast transactions into a new group of transaction called a block. Each block contain a cryptographics hash of the previous block.
The proof-of-work system, alongside the chaining of blocks makes modification of the blockchain extremely hard, as an attacker must modify all subsequent blocks in order for the modification of one block to be accepted, As new block are mined all the time, the difficulty of modifying a block increases as time passes and the number of subsequent blocks increases.
The successful miner finding the new block is rewarded with newly created bitcoin and traction fees, the reward ammounted to 12.5 newly created bitcoin per block added to the blockchain. To claim the reward, a special transcation called a coinbase is included with the processed payments. In other word the bitcoin's inventer Nakamoto set a monetry policy based on artificial scarcity at bitcoin' inception that there would only ever be 21 milion bitcoin in total. Their numbers are being released roughly every ten minutes and the rate at which they are generated would drop by by half every four year until all were in circulation.

| Bitcoin Wallet |
A wallet store the information necessery to transact bitcoins. While wallet are often described as a place to hold or store bitcoin, and allow one to access them. Bitcoin use public key cryptographics, in which two cryptographic keys, one public and one private are generated. At its most basic a wallet si a collection of these keys.
There are several types of wallets. software wallets conect to the network and allow spending bitcoins in addition to holding the credentials tht prove ownership or a subset of the blockchain. They are the most secure and reilabel way of using the network, as trust
in external parties are not required. Full clients check the validity of mined blocks, preventing them for transacting on a chain that breaks or alters network rules because of it size and complexity, storing the entire blockchain is not suitable for all computing devices.
Lightweight clients on the other hand consult a full client to send and receive transction without requiring a local copy of entire blockchain. This makes lightweight client much faster to set up and allows them to be used on low-power, low-bandwidth devices such as smartphones. When using a lightweight wallet, howerer, the user must trust the server to a certian degree, as it can report faulty value back to the user. Lightweight clients follow the longest blockchain and do no ensure it is valid requiring trust in miners.
With both types of software wallets the user are responsible for keeping their private keys in a secure place.
Beside software wallets, Internet services called online wallets offer similar functionality but may be easier to use. In this case, credential to access fund are store with the online wallet provider rather than on the users hardware. As a result, the user must have complete trust in the wallet provider. A malicious provider or a breach occurred with Mt. Gox in 2011.
Physical wallet store the credentials necessary to spent bitcoin offline. Paper wallet are simply paper printout. Another types of wallet called a hardware wallets keeps credentials offline while facilitating transactions.
