PANews reported on November 26 that Ethereum co-founder Vitalik Buterin tweeted that he expects Ethereum to continue scaling next year, but the growth will be more targeted. He proposed a possible path to increase the block gas limit by 5 times, while simultaneously raising the gas costs of inefficient operations, such as creating new storage stores (SSTOREs), calling pre-compiled contracts, large contract calls, and complex arithmetic operations, in order to improve network processing efficiency.
