Cpu Miner

cpuminer is a simple client program that performs Pooled Mining or solo mining. The program receives proposed block data from the server, for which it tries to guess a nonce value that will result in a valid block. If a block hash with at least 32 consecutive zero bits is found, the block data containing the guessed nonce value is sent back to the server. If used in Pooled Mining mode, this block is called a "share" because the server is supposed to credit the registered user's account, according to the number of shares that user has contributed, and eventually transfer an amount of bitcoins to the registered user's address.
Communication with the server is done using HTTP POST requests on port 8332 by default, containing JSON-encoded data. For pooled mining, users are required to register on such servers (so as to give their Bitcoin address) and HTTP username:password authentication is required. For solo mining, the username/password is set in bitcoin.conf.
The calculations are performed by multiple concurrent threads, so as to take advantage of the capabilities of computers with multiple CPU cores.
==Algorithms==
SHA256 hashes can be calculated in many ways by cpu-miner. Depending on the hardware that is used, one of the following supported algorithms will perform best:
*c: Linux kernel implementation of SHA256 (supported on all platforms, including Windows) .
*4way: 128-bit SSE2 optimizations which are already available as a compile-time option on the classic Bitcoin client.
*via: Implementation of the Padlock encryption optimizations on VIA CPUs.
*cryptopp: C/C++ Implementation from the Crypto++ library.
*cryptopp_asm32: 32-bit assembly implementation from the Crypto++ library.
*sse2_64: Port of ufasoft's SSE2 implementation (only supported on 64-bit Linux)
==Succession==
CPU Miner has largely been superceded by Con Kolivas's cgminer fork (with GPU support) and Luke-Jr's BFGMiner fork (with FPGA support).

Credit

You can use credit with Bitcoin for a variety of purposes, including making and accepting loans, establishing reputations, transferring value, and more.
There are two big reasons that borrowing or lending can be considered not very smart:
* Bitcoin is extremely volatile.
* Bitcoin is a bearer asset. "Not your keys not your coin."
==Bitcoin credit==
Any time a financial transaction takes place which leaves one party more obliged than the other, the obliged party is extending credit to the obliging party. This allows groups of people and organizations to cooperate even when their resources and needs are spread out over time and can be a highly valuable activity.
You can of course always lend or borrow Bitcoins casually with your friends, but when interacting with more distant social connections or for larger amounts, you may want to make use of a credit service. Such services can help you keep track of credit balances, interest rates, and amounts, and other figures, while providing many useful features such as credit score reports or even credit exchanges using Ripple routing.

CryptoNight

CryptoNight is a proof-of-work algorithm.
It is designed to be suitable for ordinary PC CPUs, but currently no special purpose devices for mining are available.
Therefore, CryptoNight can only be CPU-mined for the time being.
CryptoNight was originally implemented in the CryptoNote codebase.
== Principles ==
CryptoNight relies on random access to the slow memory and emphasizes latency dependence. Each new block depends on all the previous blocks (unlike, for example, scrypt). The algorithm requires about 2 Mb per instance:
# It fits in the L3 cache (per core) of modern processors.
# A megabyte of internal memory is almost unacceptable for the modern ASICs.
# GPUs may run hundreds of concurrent instances, but they are limited in other ways. GDDR5 memory is slower than the CPU L3 cache and remarkable for its bandwidth, not random access speed.
# Significant expansion of the scratchpad would require an increase in iterations, which in turn implies an overall time increase. "Heavy" calls in a trustless p2p network may lead to serious vulnerabilities, because nodes are obliged to check every new block's proof-of-work. If a node spends a considerable amount of time on each hash evaluation, it can be easily DDoSed by a flood of fake objects with arbitrary work data (nonce values).
