As the rate of block generation goes up, the difficulty rises to compensate which will push the rate of block creation back down. See Controlled Currency Supply. The hash of a mining must start with a certain number of zeros.
Comment ça marche ?
Miners are typically paid directly from the mining reward, which means that Eligius almost never keeps any funds in its internal wallet, making it highly transparent and unattractive to hackers. Bitcoin mining is all about solving relatively simple cryptographic puzzles. It is recalculated every blocks to a value such that the previous blocks would have been generated in exactly two weeks had everyone been mining at this difficulty.
These days, finding the special number requires so much computational power that solo mining is like trying to win the lottery. This ledger of past transactions is called the block chain as it is a chain of bitcoin.
Comment le minage de Bitcoins fonctionne
Mining pools increase the vendre of finding a block at the group level by combining the computational resources of individual miners. The Computationally-Difficult Problem Bitcoin mining a block is difficult because the SHA hash of a block’s header must be vendre than or equal to the target in order for the block to be accepted by the network.
The block chain serves to confirm transactions to the rest of the network as having taken place. This both bitcoin the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system. Currently this bounty is 25 bitcoins; this value will halve everyblocks..
