Listen to the audio version! Hey DEFI TIMES community, The need for scalability has never been more important than in 2020 and 2021. DeFi summer has shown us that gas prices rise to unsustainable highs during times of intensive usage. It currently costs $5 to make an ETH transaction and way more to transfer ERC-20 tokens between two accounts. Ethereum will not scale with a PoW consensus algorithm. So the Ethereum community decided to switch to Proof of Stake and turn Ethereum into a sharded blockchain.
