How does mining help secure Bitcoin?
Mining creates the equivalent of a competitive lottery that makes it very difficult for anyone to consecutively add new blocks of transactions into the block chain. This protects the neutrality of the network by preventing any individual from gaining the power to block certain transactions. This also prevents any individual from replacing parts of the block chain to roll back their own spends, which could be used to defraud other users. Mining makes it exponentially more difficult to reverse a past transaction by requiring the rewriting of all blocks that occurred after the target transaction.
What do I need to start mining?
In the early days of Bitcoin, anyone could find a new block using their computer’s CPU. As more and more people started mining, the difficulty of finding new blocks increased greatly to the point where the only cost-effective method of mining today is using specialized hardware. This is why we recommend third party cloud mining.
What does MH/s, GH/s mean?
These abbreviations stand for the hashing power that your miner is generating. MH/s stands for megahash per second and GH/s stands for gigahash per second. There is a direct correlation between how fast your miner works and how profitable it will be.
What does W/Gh and W/Th mean?
W/Gh and W/Th are abbreviations for watts per gigahash and watts per terahash. These metrics calculate how many hashes a miner can run per watt of electricity. Mining hardware with lower W/Gh and W/Th are more efficient. Currently, the Antminer S7 and Avalon6 are the most efficient miners available for purchase, at 0.25 W/Gh and 0.29 W/Gh, respectively.
What does hashing mean?
The term “hashing” means how quickly your hardware is processing data from the Blockchain and solving the complex mathematical equations that are required to earn bitcoins.
