It is reported that Apple’s A12 bionic chip integrates 6.9 billion transistors with a transistor density of 83.9 million per square millimeter, while the A11 bionic chip has a transistor density of 49 million per square millimeter. In contrast, Apple’s A12 bionic chip has 70% more transistors per square millimeter than the A11 bionic chip.
In addition, the A12 bionic chip is Apple's first chip with a 7nm process technology. Compared with the previous generation, its speed has increased by up to 15%, the four energy-efficient cores can save energy by up to 50%, and the GPU speed has increased by up to 50%.
Mining is the process of creating a block of transactions to be added to the Ethereum blockchain in Ethereum's now-deprecated proof-of-work architecture.
The word mining originates in the context of the gold analogy for cryptocurrencies. Gold or precious metals are scarce, so are digital tokens, and the only way to increase the total volume in a proof-of-work system is through mining. In proof-of-work Ethereum, the only mode of issuance was via mining. Unlike gold or precious metals however, Ethereum mining was also the way to secure the network by creating, verifying, publishing and propagating blocks in the blockchain.
Mining ether = Securing the Network
Mining is the lifeblood of any proof-of-work blockchain. Ethereum miners - computers running software - used their time and computation power to process transactions and produce blocks prior to the transition to proof-of-stake.
