Blue Fury 2, Retrieved January 30, Retrieved September 2, As later blocks are chained after it, the work to change the block would include redoing the work for each subsequent block. Majority consensus in bitcoin is represented by the longest chain, which required the greatest amount of effort to produce.
If a majority of computing power is controlled by honest nodes, the honest chain will grow fastest and outpace any competing chains. To modify a past block, an attacker would have to redo the proof-of-work of that block and all blocks after it and then surpass the work of the honest nodes. The probability of a slower attacker catching up diminishes exponentially as subsequent blocks are added. To compensate for increasing hardware speed and varying interest in running nodes over time, the difficulty of finding a valid hash is adjusted roughly every two weeks.
If blocks are generated too quickly, the difficulty increases and more hashes are required to make a block and to generate new bitcoins. Bitcoin mining is a competitive endeavor. An " arms race " has been observed through the various hashing technologies that have been used to mine bitcoins: Computing power is often bundled together or "pooled" to reduce variance in miner income.
Individual mining rigs often have to wait for long periods to confirm a block of transactions and receive payment. In a pool, all participating miners get paid every time a participating server solves a block. This payment depends on the amount of work an individual miner contributed to help find that block. Bitcoin data centers prefer to keep a low profile, are dispersed around the world and tend to cluster around the availability of cheap electricity. In , Mark Gimein estimated electricity consumption to be about To lower the costs, bitcoin miners have set up in places like Iceland where geothermal energy is cheap and cooling Arctic air is free.
