PAUL COUNSEL WEALTH CREATION INVESTING
Bitcoin mining serves several functions: It is a method for distributing new coins. It is part of a more complete system for ensuring only valid transactions are added to the blockchain. It is a method for prioritizing transactions given limited throughput it creates a fair market for limited block space.
It provides financial incentive for participants miners to dedicate resources to the network, and the resources dedicated help secure the network from attackers. Note that attackers here primarily refers to miners themselves. In other words, by making it expensive to mine, Bitcoin ensures miners follow the rule. Proof-of-Work mining helps to secure the Bitcoin network by requiring potential attackers to commit more resources to an attack than they could hope to gain from the attack itself.
In other words, it ensures that attacking Bitcoin is a money-losing and very costly prospect, making it exceedingly unlikely to occur. The process is summarized in the Bitcoin white paper : New transactions are broadcast to all nodes. Each node collects new transactions into a block.
Each node works on finding a difficult proof-of-work for its block. When a node finds a proof-of-work, it broadcasts the block to all nodes. Nodes accept the block only if all transactions in it are valid and not already spent. Nodes express their acceptance of the block by working on creating the next block in the chain, using the hash of the accepted block as the previous hash.
Let's break that down into a little more detail. To begin, miners are the ones who propose updates to the ledger and only miners who have successfully completed the Proof of Work are permitted to add a new block. This is coded into the Bitcoin protocol. Miners are free to select valid transactions from a pool of potential transactions that are broadcast to the network by nodes. Such transactions are collected into the 'mempool.
This gives rise to the fee market, which helps to ensure the limited block space is used fairly and efficiently. The first miner to complete the Proof of Work broadcasts her proposed new block to the wider network of nodes who then check to ensure that the block follows the rules of the protocol. The key rules here are 1 all transactions in the block are valid ie. If it does, nodes send it on to other nodes who complete the same process. In this way, the new block propagates across the network until it is widely accepted as the 'truth.
Moreover, due to network delays and geographic separation, nodes may receive new proposed blocks at slightly different times. Note that one miner's newly proposed block could be slightly different from another's. This is because, as mentioned, miners are the ones who choose which transactions to include in a block - and even though they tend to optimize for profitability, location and other factors introduce variation.
When two miners send out different new blocks, competing versions of the 'truth' begin to propagate across the network. The network ultimately converges on the 'correct' version of the truth by selecting the chain that grows longer at faster rate.
Let's break down that last part. Imagine there are two competing chains. Statistically, one of the miners working on version A is likely to complete the Proof of Work first, broadcasting the new version out to the network. Since nodes always select for the longest chain, version A will quickly come to dominate the network. In fact, the probability that version B will grow faster vanishes exponentially with each additional block such that by the time six blocks have been added, it's a statistical impossibility.
For this reason, a transaction that has been confirmed in six blocks is, for most participants, considered to be set in stone. Note that a block which doesn't end up becoming part of the longest chain version B in our example above is known as an orphan block. It is estimated that such blocks are created between 1 and 3 times per day.
Transactions that are included in an orphan block are not lost. That's because if they weren't already included in the version that ends up being the longest chain, they'll end up being added to the next block of the longest chain. Bitcoin miners are awarded BTC when they find a random number that can only be generated by running the hashing algorithm over and over again.
This process is analogous to a lottery where buying more tickets increases your chances of winning. By dedicating more computing power to the hashing algorithm, miners are effectively buying more lottery tickets.
The difficulty level for the Proof of Work algorithm is automatically adjusted every 2, blocks, or roughly every 2 weeks. Adjustments are made with the goal of keeping the mining of new blocks constant at 10 minutes per block. The difficulty adjustment factors in the total volume of computing power, or 'hashpower,' being applied to the hashing algorithm. As computing power is added, the difficulty is increased, making mining more difficult for everyone.
If computing power is removed, difficulty is reduced, making mining easier. Note that the difficult adjustment system makes bitcoin mining quite different from the mining of precious metals. If, for example, the price of gold rises, more miners are enticed to join the market.
The addition of more gold miners will inevitably result in more gold produced. In the early days of bitcoin, it was possible to mine with your computer CPU or high speed video processor card. Today that's no longer possible. Custom Bitcoin ASIC chips offer performance up to x the capability of older systems have come to dominate the Bitcoin mining industry.
Bitcoin mining with anything less will consume more in electricity than you are likely to earn. It's essential to mine bitcoins with the best bitcoin mining hardware built specifically for that purpose. Several companies such as Avalon offer excellent systems built specifically for bitcoin mining. This greatly simplifies the process but increases risk because you do not control the actual physical hardware. Being listed in this section is NOT an endorsement of these services.
