How POS mining works on the Ethereum 2 network. Synchronization committee and light clients after the Altair hardfork.
ethereum 2 pos mining Classic POW mining on processors, asics and video cards has existed since the emergence of Bitcoin in 2009. POS mining has also been around since 2012 (PPCoin cryptocurrency), but Ethereum's much-anticipated transition to POS mining will have little to do with what we have come to understand as POS mining. Ethereum 2 POS mining is not just storing a certain amount of cryptocurrency on a wallet or node, but also performing the necessary calculations to maintain the network in working order and protect it from hacker attacks. In other words, POS mining in Ethereum network will be a kind of symbiosis of POS and POW mining, where there will be no concept of network hashrate, i.e. there will be no need to constantly increase the capacity of your equipment to compete with other miners. Hacking protection will now be based not on the difficulty of getting 51% hash capacity, but on running 51% number of nodes with a balance of 32ETH for each node. Therefore, the power of your hardware is of secondary importance, you only need to provide a minimum level of performance and further capacity increase will have no effect whatsoever. As of today, the ETH2 network contains 250.480 validators, or 8.239.286 ETH, which means that 51% of the validators would need to be controlled, which means that to attack the ETH2 network you will need 125.000 validators, or 4 million 200 thousand ETH (17 billion dollars at the current exchange rate). That's a lot of money. But even if someone wanted to carry out such a plan, 51% of the validators would not be enough, because there are so-called committees in the ETH2 network.
