Elon Musk is no stranger to leaving people entertained, and at times bewildered, on Twitter. Sunday saw him return to Twitter for just that. So informative pic. The tweet, dripping in sarcasm, has made Musk's followers wonder if it is a cryptic announcement for "grapecoin". This also comes days after Musk's announcement on Friday that Tesla Inc merchandise can be bought using the dogecoin.

Cryptocurrency mining is the process by which transactions are validated and new coins are minted in a decentralized cryptocurrency network. The process of creating new coins in a cryptocurrency network is referred to as "mining" because it is analogous to a digital version of the process by which gold is extracted from the earth and added to circulation. In a decentralized blockchain network, miners are needed to validate transactions and preserve the integrity of the distributed digital ledger.

Mining rewards are used as economic incentives to encourage people to participate in mining and to help secure the decentralized network. These rewards come in the form of transaction fees paid by users when they transfer funds as well as block rewards, which are transactions that send newly created coins to the cryptocurrency wallet of the miner.

The process of cryptocurrency mining can vary greatly in how it's implemented from both a software and hardware perspective. The different software implementations amount to different methods of incentivizing miners to be honest by making it profitable to mine according to the network consensus rules, and at the same time making it cost prohibitive to attempt an attack that breaks the network consensus rules.

In other words, the goal is to ensure that the rational participants in the network act in their own best interest by only validating legitimate transactions and by casting out i. Legitimate transactions are those in which the sender in the transaction has enough funds in their cryptocurrency wallet to cover the amount they are sending.

Cryptographic hash functions and public key cryptography are critical technologies used in tandem in order to enforce the network rules and maintain the integrity of the blockchain without requiring users to trust the miners.

Some examples of different types of mining implementations are:. The original cryptocurrency, Bitcoin , uses a proof-of-work consensus mechanism based on the SHA hashing algorithm. At present, Ethereum is also using PoW. However, there is a planned switch to proof-of-stake through an upcoming Casper implementation planned for or Proof-of-activity is used by two prominent projects, Decred and Espers.

The different types of hardware involved in cryptocurrency mining vary depending on the specific network architecture of the cryptocurrency in question. Attempting to mine Bitcoin with any hardware that isn't specially designed for the task will most likely not be profitable. Other networks, such as Vertcoin , are intended to be ASIC-resistant, meaning that they can be mined profitably without specialized hardware.

However, full ASIC resistance is only theoretical. In reality, cryptocurrencies that intend to be ASIC-resistant may have to change their mining algorithm one or more times in order to make ASICs developed for it obsolete. In fact, cryptocurrency mining at one point resulted in sharp increases in demand for GPU chips, which subsequently caused a short supply and increase in prices from major chip manufacturers such as AMD and Nvidia.

Blocks are generated through PoW mining mechanisms and then a switch to a proof of stake style mechanism occurs where validator nodes stake tokens in order to be chosen to sign these mined blocks.

Proof-of-capacity PoC is a means of proving that a network participant has allocated available memory or disk space to the network to show a financial interest in the network.

Bitcoin Mining

Bitcoin mining is a transaction record process with bitcoins to blockchain — the public database of all the operations with Bitcoin, which is responsible for the transaction confirmation. Network nodes use blockchain to differ the real transactions from the attempt to spend the same facilities twice. The main mining objective is reaching a consensus between network nodes on which transactions consider legitimate. Bitcoin mining is the process of issuing bitcoin, built on the calculation of mathematical problems, is the only way to create a cryptocurrency.
