/2 Ethereum currently functions on Proof of Work (PoW) – the mining model.
This means that new blocks of ETH are mined by miners solving complex mathematical problems using high computational power.
Biggest problem → inefficient, it requires A LOT of energy
/2以太坊目前在工作证明（PoW）——采矿模型上发挥作用。
这意味着新的ETH区块由矿工开采，他们使用高计算能力解决复杂的数学问题。
最大的问题→ 效率低，需要大量能源
