As more miners join, the rate of block creation will go up. As the rate of block generation goes up, the difficulty rises to compensate which will push the rate of block creation back down. Any blocks released by malicious miners that do not meet the required difficulty target will simply be rejected by everyone on the network and thus will be worthless.


More fundamentally, miners argue that the current boom is simply the first rough step to a much larger technological shift that the basin would do well to get into early on. “What you can actually do with the technology, we’re only beginning to discover,” Salcido says. “But the technology requires a platform.” And, he says, as the world discovers what the blockchain can do, the global economy will increasingly depend on regions, like the basin, with the natural resources to run that platform as cheaply as possible.
Each time you request blockchain data from a wallet, the server may be able to view your IP address and connect this to the address data requested. Each wallet handles data requests differently. If privacy is important to you, use a wallet that downloads the whole blockchain like Bitcoin Core or Armory. Tor can be used with other wallets to shield your IP address, but this doesn’t prevent a server from tying a group of addresses to one identity.

For years, few residents really grasped how appealing their region was to miners, who mainly did their esoteric calculations quietly tucked away in warehouses and basements. But those days are gone. Over the past two years, and especially during 2017, when the price of a single bitcoin jumped from $1,000 to more than $19,000, the region has taken on the vibe of a boomtown. Across the three rural counties of the Mid-Columbia Basin—Chelan, Douglas and Grant—orchards and farm fields now share the rolling landscape with mines of every size, from industrial-scale facilities to repurposed warehouses to cargo containers and even backyard sheds. Outsiders are so eager to turn the basin’s power into cryptocurrency that this winter, several would-be miners from Asia flew their private jet into the local airport, took a rental car to one of the local dams, and, according to a utility official, politely informed staff at the dam visitors center, “We want to see the dam master because we want to buy some electricity.”
Ultimately, Bitcoin mining is becoming an arms race. In the early days, anyone with a decent PC could generate Bitcoins through Bitcoin mining. Today, you need to collaborate with other Bitcoin miners in pools, strategically choose the location of your Bitcoin mining operation, and purchase ASIC-powered computers that are specially designed to handle Bitcoin mining.
Because of bitcoin's decentralized nature and its trading on online exchanges located in many countries, regulation of bitcoin has been difficult. However, the use of bitcoin can be criminalized, and shutting down exchanges and the peer-to-peer economy in a given country would constitute a de facto ban.[164] The legal status of bitcoin varies substantially from country to country and is still undefined or changing in many of them. Regulations and bans that apply to bitcoin probably extend to similar cryptocurrency systems.[165]
If fewer people begin to accept Bitcoin as a currency, these digital units may lose value and could become worthless. There is already plenty of competition, and though Bitcoin has a huge lead over the other 100-odd digital currencies that have sprung up, thanks to its brand recognition and venture capital money, a technological break-through in the form of a better virtual coin is always a threat.

Unauthorized spending is mitigated by bitcoin's implementation of public-private key cryptography. For example; when Alice sends a bitcoin to Bob, Bob becomes the new owner of the bitcoin. Eve observing the transaction might want to spend the bitcoin Bob just received, but she cannot sign the transaction without the knowledge of Bob's private key.[14]

In January 2009, the bitcoin network was created when Nakamoto mined the first block of the chain, known as the genesis block.[18][19] Embedded in the coinbase of this block was the following text: "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks."[10] This note has been interpreted as both a timestamp and a comment on the instability caused by fractional-reserve banking.[20]:18
