Gains are defined as increases in value. When used to describe cryptocurrency, it is an increase in value and profit.

Writing a transaction into a public blockchain requires the use of computing power. This is accomplished by miners who allocate compute resources on a distributed network. Gas is a fee charged by the miner as a form of compensation. Usually, the fee is paid in the form of cryptocurrency.

Gas limit is an amount of ethereum and it is multiplied by a very small amount of ethereum to pay people to record transactions and do other software actions. If the amount of gas is insufficent to complete the work, the work will fail. On the other hand, you can pay a bit more gas and expect the computers to complete your task sooner.

Gas is calculated by multiplying a very small amount of ethereum, known as “gwei” and “gas price”, and multiplying that by how much you want to spend, known as the “gas limit”. Gas limit is calculated in large numbers, think tens of thousands. The average gas limit for sending ethereum is 21,000. Because some software actions may require a larger gas limit, you need to be sure you include a large enough gas limit or your task will fail.

Gas price is a very small amount of ethereum and it is multiplied by an amount known as gas limit to pay people to record transactions and do other software actions. If the amount of gas is insufficent to complete the work, the work will fail. On the other hand, you can pay a bit more gas and expect the computers to complete your task sooner. Gas is calculated by multiplying a very small amount of ethereum, known as “gwei” and “gas price”, and multplying that by how much you want to spend, known as the “gas limit”. The very small amounts of ethereum used in gas price are known as gwei. 1 ethereum = 1 billion (1,000,000,000) gwei. A typical gas price is 20 gwei, but it can go as high as 50 during peak usage and as low as 2 gwei for a slower transaction.

A private key that gives the holder the right to create the blocks in a private blockchain. It can be held by a single entity or a set number of entities. This is an alternative to the proof-of-work model, as instead of getting multiple random nodes to approve a transaction, a group of specific nodes are given the authority to approve. This is a far faster method.

Another alternative to proof of work, this caps the reward given to miners for providing their computational power to the network at that miner’s investment in the cryptocurrency. So if a miner holds three coins, they can only earn three coins. The system encourages miners to stick with a certain blockchain rather than converting their rewards to an alternate cryptocurrency.

In order to receive a reward for mining a cryptocurrency, miners must show that their computers contributed effort to approve a transaction. A variable is added to the process of hashing a transaction that demands that effort before a block can be successfully hashed. Having a hashed block proves the miner did work and deserves a reward – hence proof of work.
