By now you have probably heard of bitcoin, even if you haven't used it yourself. Launched 11 years ago, bitcoin is a digital currency that. But the hackings should scare anyone with a mobile phone, an email account or an online bank account.

It also tries to add some perspective on the energy problem. Warning: This article gets a bit technical. Digital currencies have an inherent problem. I have 2 coins now. It is called double spending. The solution is to record ownership information.

Ledger Ownership and amount can be verified using this record. This record is called a ledger. Banks use ledgers to store your ownership and spending. Banks secure and maintain the private ledgers. Government authorities act as monitoring authority for the banks. Anyone can check and edit the ledger.

Public ledgers have two issues: Editing the ledger requires a trusted party. The identity verification of the trusted party should be fast. Proof of Work asks a miner to generate a token nonce. The nonce verification happens in less than a second. After verification, the miner can edit the ledger and earn reward coins. But, there is a problem. This time delay is called latency. In Bitcoin, it is the time difference between block creation action and acceptance by all peers reaction.

This process of a block being accepted by other peers is known as block propagation. Because of this delay there are always multiple versions of a blockchain. Wikipedia entry on blockchain has a diagram: blockchain Green box is our genesis block.

Black boxes are blocks accepted by the whole network. This chain of black blocks is called main chain. Purple and black blocks are mined at the same time. Purple boxes are valid blocks but not accepted by the whole network.

These are called orphan blocks. This latency causes two problems. This can cause double spending. Visually, think a transaction included in purple block 1 but not black block 1. This can be due to latency or someone maliciously changing the structure. Whatever the case, coins from purple 1 can be re-spent and included in black block 2. Second, orphan and main blocks both require same mining effort.

So, orphan block is essentially wasting computing resource. Additionally, the network needs to decide the valid block and build from there. This is called block reorganization. Think about the 2nd and 3rd purple block. That is a chain of two blocks. So, cryptocurrency network needs to work together and find if that chain is invalid.

This situation was even worse back in Confirmations and Maturity The solution for transaction issue is to measure probability of double spending. All cryptocurrencies use the same metric — confirmations. Once a transaction is included in a block, number of confirmation becomes 1. Probability of a block being an orphan grows smaller and smaller with each additional block added. There is 1 additional blocks on top of the transaction block. Block rewards, the newly minted coins, need confirmations.

This is known as block maturity. New coins can only be spend after maturing. First, selecting a block generation time is a balancing act. This needs to be: High to delay blocks and minimize probability of an orphan block. Low to allow faster transactions. Low to allow faster confirmations.

Confirmation counting starts from transaction block. Bitcoin block generation time is 10 minutes. The recommended number of confirmations is 6 blocks. So, after an hour a bitcoin transaction is nearly immune from double spending. Second, difficulty retargeting keeps the network within generation time boundary.

Difficulty increases, if block generation is too fast. Mining becomes harder. Reverse is also true. Difficulty reduces, if blocks are taking too much time. Cloud mining is supported by mining companies setting up the mining rigs at their own facility, with a cloud miner only needing to register and purchase shares or a mining contract. The user essentially buying a proportion of the Bitcoin miners hash power.

No ASIC vendor endorsement. If there are no advertisements from the ASIC vendor, the mining company may not even own the hardware. No photos of the hardware or data center of the mining company. No limit imposed on sales or does not display how much hash rate sold against used in mining.

Referral programs and social networking. A mining company willing to pay high referral fees should be avoided as these may well be Ponzi schemes. Anonymous operators should certainly be avoided… No ability to sell your position or get the money out upon sale. However, as miners have continued to use their technical abilities to develop hardware capable of earning at a much greater number of Bitcoins, leaving CPU and laptop users behind, using a laptop is now unlikely to yield a single Bitcoin even if mining for years.

The use of GPUs increased mining power by as much as x, with significantly less power usage, saving on sizeable electricity bills. Next came FPGAs, Field Programmable Gate Aray , the improvement here being in the power usage rather than actual mining speed, with mining speeds slower than GPUs, while power consumption fell by as much as 5x.

Power savings led to the evolution of mining farms and the Bitcoin mining industry as it is known today, where Bitcoin mining power is controlled by a mining few more commonly known as the Bitcoin Cartel. Evolution of software has slowed, with nothing in the marketplace at present or in development that is expected to replace ASICs, with ASIC chips likely to see minor tweaks at best to try and squeeze out greater efficiencies , though it will only be a matter of time before the Bitcoin world comes up with something newer and faster as miners catch up on hashing power.

What is Proof-of-Work? Proof of work is also referred to as PoW. All of the blocks in a Bitcoin blockchain have a series of data referred to as nonces, these are meaningless data strings attached to each block of a Bitcoin blockchain. The proof of work is therefore difficult to produce, while considered simple to verify, the production of a proof of work being a random process, requiring mining rigs to calculate as many computations per second as possible so as to increase the probability of producing the proof of work.

What is Bitcoin Mining Difficulty? Bitcoin mining difficulty is the degree of difficulty in finding a given hash below the target during the proof of work. As mining difficulty increases, target value declines and vice-versa.

In basic terms, as more miners join the Bitcoin network, the rate of block creation increases, leading to faster mining times. As mining times speed up, mining difficulty is increased, bringing the block creation rate back down to the desired 10 minutes as mentioned previously.

Once the mining difficulty is increased, the average mining time returns to normal and the cycle repeats itself about every 2-weeks. Wallets can be downloaded for free as can miner programs and once downloaded its ready to go. The reality is that your desktop computer or laptop will just not cut it in the mining world, so the options are to either make a sizeable investment and create a mining rig, or joining a mining pool or even subscribe to a cloud mining service, the latter requiring some degree of due diligence as is the case with any type of investment.

In mining pools, the company running the mining pool charges a fee, whilst mining pools are capable of solving several blocks each day, giving miners who are part of a mining pool instant earnings. While you can try to mine with GPUs and gaming machines, income is particularly low and miners may, in fact, lose money rather than make it, which leaves the more expensive alternative of dedicated ASICs hardware.

Miners make Bitcoin by finding proof of work and creating blocks, with the current number of Bitcoins the miner receives per block creation standing at Can you get rich off the mining process? Don't miss a thing!
