Bitcoin Mining Definition

Bitcoins are stewarded by miners, the network of people who contribute their personal computer resources to the bitcoin network. Miners act as ledger keepers and auditors for all bitcoin transactions. Miners are paid for their accounting work by earning new bitcoins for the amount of resources they contribute to the network. Each blockchain is unique to each user and the user's personal bitcoin wallet. All bitcoin transactions are logged and made available in a public ledger, which ensures their authenticity and prevents fraud.

This process prevents transactions from being duplicated and people from copying bitcoins. While every bitcoin records the digital address of every wallet it touches, the bitcoin system does not record the names of the people who own wallets.

In practical terms, this means that every bitcoin transaction is digitally confirmed but is completely anonymous at the same time. So, although people cannot easily see the personal identity or the details of the transaction, they can see the verified financial history of a bitcoin wallet.

This is a good thing, as a public history adds transparency and security to every transaction. Bitcoin mining involves commanding a home computer to work around the clock to solve proof-of-work problems computationally intensive math problems. Each bitcoin math problem has a set of possible digit solutions. A desktop computer, if it works nonstop, might be able to solve one bitcoin problem in two to three days, however, it might take longer.

A single personal computer that mines bitcoins may earn 50 cents to 75 cents per day, minus electricity costs. Bitcoin mining is profitable only for those who run multiple computers with high-performance video processing cards and who join a group of miners to combine hardware power. This prohibitive hardware requirement is one of the biggest security measures that deter people from trying to manipulate the bitcoin system.

People who take reasonable precautions are safe from having their personal bitcoin caches stolen by hackers. There are two main security vulnerabilities when it comes to bitcoin:. More than hacker intrusion, the real loss risk with bitcoin revolves around not backing up a wallet with a fail-safe copy.

There is an important. The public collapse of the Mt. Gox bitcoin exchange service was not due to any weakness in the bitcoin system. Rather, the organization collapsed because of mismanagement and the company's unwillingness to invest in appropriate security measures. Gox had a large bank with no security guards. There are three known ways that bitcoin currency can be abused:. Bitcoins can be double-spent in some rare instances during the confirmation interval. Because bitcoins travel peer-to-peer, it takes several seconds for a transaction to be confirmed across the P2P computers.

During these few seconds, a dishonest person who employs fast clicking can submit a second payment of the same bitcoins to a different recipient.

Because bitcoin mining is best achieved through pooling joining a group of thousands of other miners , the organizers of each pool choose how to divide bitcoins that are discovered. With Mt. Gox as the biggest example, the people running unregulated online exchanges that trade cash for bitcoins can be dishonest or incompetent. The only difference is that conventional banking losses are partially insured for the bank users, while bitcoin exchanges have no insurance coverage for users.

There is a lot of controversy around bitcoins. This may change, as unregulated money is a threat to government control, taxation, and policing. Bitcoins have become a tool for contraband trade and money laundering because of the lack of government oversight. The value of bitcoins skyrocketed in the past because wealthy criminals purchased bitcoins in large volumes.

Because there is no regulation, people can lose out as a miner or investor. Bitcoins are transferred through a peer-to-peer network between individuals, with no middleman bank to take a slice.

Bitcoin wallets cannot be seized or frozen or audited by banks and law enforcement. Bitcoin wallets cannot have spending and withdrawal limits imposed on them. Nobody but the owner of the bitcoin wallet decides how the wealth is managed. Conventional payment methods such as a credit card charge, bank draft, personal check, or wire transfer benefit from being insured and reversible by the banks involved.

In the case of bitcoins, every time bitcoins change hands and change wallets, the result is final. Simultaneously, there is no insurance protection for a bitcoin wallet.

If a wallet's hard drive data or the wallet password is lost, the wallet's contents are gone forever. Cryptocurrency What Are Bitcoins? Tweet Share Email. Was this page helpful? Thanks for letting us know!
