V God: Pushing Layer 2 expansion, it is proposed to increase the gas limit when hard forks in Istanbul

According to Trustnodes' August 30 report, Ethereum co-founder Vitalik Buterin said that if people want to increase the gas limit, then:

“I recommend launching an event on Reddit/Twitter to promote the reasons for increasing the gas limit. Historically, large mine pools have felt the pressure of the community and listened to their opinions.”


The Ethereum network is operating at full capacity, with a limit of 8 million gas usage per block, equivalent to 50 billion per day.

At the same time, the orphaned blocks and uncle blocks of Ethereum have fallen sharply to 25% of the peak in January 2018, when miners did not raise the gas limit.

About 40% of miners currently vote for the increase in gas limits, including F2Pool and Sparkpool. As long as Ethermine or Nanopool agree, the gas limit can be increased. But Buterin said it would be better to wait a little longer. He said:

“It’s not clear now that it’s the best time to increase the gas limit; it’s better to increase the gas limit at the same time as Istanbul’s hard fork, and the most risky opcodes will look The cost of gas to them soars, so a higher gas cap will become safer."

There are many gas-related improvements in Istanbul forks that may in turn make more deals in line with current gas restrictions.

The upgrade was intended to be completed within a few weeks of the developer's meeting, but due to some delays that Parity has not yet implemented, the upgrade has now been postponed to November.

Mixing the second layer

As far as the current situation is concerned, the Ethereum network is not crowded, and the transaction fee is about one cent, but from time to time there will be some DAPPs sending a lot of transaction information to it, so some traffic will be generated.

Simply increasing the gas limit may be a solution, but a more efficient approach might be to use hybrid second layers.

Snark or Starks can be enhanced by using snarky starks for more work with less storage or data requirements.

This solves many of the problems faced by Lightning Network or Plasma, and Buterin wants to know why not combine things like snarky starks and Plasma.

It's not clear how it is implemented, but Buterin said that the Plasma chain can "send some data for each user on the chain regularly", thereby reducing local storage and/or verification requirements. He concludes that:

"Mixed routing opens the door to deploying fully versatile Ethereum smart contracts relatively quickly in the 'quasi-layer-2' architecture."

All of this must be available to the in-flight users on the back end of some wallet or Metamask plug-ins, because you need to deposit Eth into a smart contract or lock Eth before you can interact with users in the smart contract system.

In terms of adoption, this may be a problem with chickens, because all of these second layers are useful, even when people "join". However, it must be useful for the person to join, and if people don't join it, it's useless, so booting may not be easy.

To motivate it, in Bitcoin, they just make the chain transactions expensive. In Ethereum, they use the second layer as an optional layer, especially for Dapp, something like the starks-based Plasma has potential use, because you have to store Eth anyway.

The incentive here is to make it easier for users to use, because with this second layer, you need to trade much less on the chain, reducing the time or cost of waiting for confirmation.
