Vitalik: Ethereum requires a contract size limit due to DoS risk considerations

BlockBeats news, December 23, Ethereum founder Vitalik responded to community questions regarding “why Ethereum still imposes a contract size limit”: due to DoS risk considerations. After Ethereum’s state structure is upgraded to a unified binary tree (EIP-7864), it is expected to achieve unlimited contract size, but issues such as gas fees and mechanism design for deploying extremely large contracts still need to be resolved. Currently, based on per-byte creation costs, the practical contract limit is approximately 82KB.

PANews reported on December 31 that Tom Lee, co-founder of Fundstrat and chairman of BitMine, wrote on the X platform: "Typically, during these last holiday trading sessions, many institutional investors exit the market, and algorithmic trading programs and bot trading programs begin to dominate the market, along with sell-offs for tax avoidance. These constitute the market dynamics in the last few days of December." Previously, in BitMine's announcement of acquiring 44,463 ETH last week, Tom Lee mentioned that market activity tends to slow down as the year enters its final weeks of holiday season. Year-end tax-avoidance selling depresses cryptocurrency and cryptocurrency-related stock prices, with this effect typically most pronounced between December 26th and December 30th; therefore, they are adjusting their market strategy accordingly. Earlier today, it was reported that Bitmine pledged another 118,944 ETH and increased its holdings by 32,938 ETH .
