What is the calculation unit of computing power (pib computation unit)?

According to bitcoin.com, what is the calculation unit of computing power? How is the size of computing power determined? It includes the hash value generated by mining, encryption algorithms, and corresponding software development tools, among others. Among them, the most famous is the hash function (SHA) – the relationship between the time length, quantity, and difficulty required to generate a new block by adding a random number in the block. Bitcoin’s proof of work mechanism can be used to measure the energy consumption of network participants and optimize the design of blockchain technology. Currently, popular applications on the market include Bitcoin Lightning Network, Ethereum 2.0, Polkadot, and more.

Unit of computing power: pib

According to BitInfoCharts data, the current total network computing power of Bitcoin is 120.22PiB. The highest value occurred at block height 730,000, and the lowest value reached the number of POW public chain mining pools in Guizhou province, reaching a historical high. The number of addresses with the largest holdings has also exceeded 1,000, more than twice as much as yesterday, indicating that there are already a large number of miners choosing to participate in this field. According to previous reports, Vitalik Buterin, co-founder of Ethereum, stated that the ETH2.0 network is expected to go live on the testnet in November and plans to deploy a new blockchain called PoS on the mainnet.
