The region’s energy company says bitcoin mining is becoming so popular that the country will likely use more electricity to mine coins than power homes in 2018.

In October 2018 Russia will become home to one of the largest legal mining operations in the world, located in Siberia.

With each account controlling its own transactions, no traditional proof-of-work mining is required, allowing for feeless, instantaneous transactions.

Iceland has become a haven for cryptocurrency miners in part because of its cheap electricity.

Unlike conventional blockchains, some directed acyclic graph cryptocurrencies utilise a pay-it-forward system, whereby each account performs minimally heavy computations on two previous transactions to verify.

Other cryptocurrencies like Nano utilise a block-lattice structure whereby each individual account has its own blockchain.

The rate of generating hashes, which validate any transaction, has been increased by the use of specialized machines such as FPGAs and ASICs running complex hashing algorithms like SHA-256 and Scrypt.

With more people venturing into the world of virtual currency, generating hashes for this validation has become far more complex over the years, with miners having to invest large sums of money on employing multiple high performance ASICs.

The block time is the average time it takes for the network to generate one extra block in the blockchain.
