Ethereum reverted from Ethereum1.0 to Ethereum 2.0, in order to make the coin fasting up transactions and not slowing down when their is plenty of transactions to process just the way the previous one was doing. When their is congestion based on multiply request to process transactions the Ethereum1.0 will slow down the processing. Which causes delay before the coin gets to the destination you approved it. That's why Ethereum owners created the 2.0 type to rectify such lingering issues around their blockchain.
