Ethereum London upgrade will postpone the difficulty bomb to December


-The Ethereum difficulty bomb was originally scheduled to be launched this summer.

– Ethernet Square core developers  Tim Beiko  and  James Hancock  said the team would defer difficult bomb to  12  months.

– This may be the last time developers need to take such action.

Ethereum developers agreed on Friday to postpone a “difficulty bomb”, which, if not dealt with, will start to slow down the Ethereum network this summer.

The Ethereum “Difficulty Bomb” is a piece of code embedded by Ethereum developers in 2015 to artificially slow down the speed of Ethereum issuance by gradually increasing the difficulty of blockchain mining. This mechanism is designed to make a huge shift from Ethereum to a proof-of-stake ( PoS ) mechanism algorithm.

Under the current proof-of-work consensus mechanism, miners will win rewards every time they create a new block and add it to the blockchain. But when the Ethereum difficulty bomb is set to “detonate”, the difficulty for miners to obtain rewards through mining will increase exponentially.

Ethereum 2.0 will switch the network from Proof of Work (PoW) to Proof of Stake (PoS).

It now takes an average of  13  seconds to mine a block in Ethereum . If the difficulty bomb is not delayed, it will take more than 20  seconds to verify a block by the end of the year  .

On Friday, Ethereum developers agreed on how many blocks would be needed to delay the difficulty bomb by  December  .



On  May  14  , the core developers of Ethereum held a conference call. Ethereum developer  Tim Beiko  updated the results of the conference and said that most of the conference time was focused on solving the final details of the London upgrade. The London upgrade will include  EIP-3541 and EIP-3554 . Among them,  EIP-3541  prevents the deployment of contracts beginning with ” 0xEF ” to lay the foundation for large-scale  EVM  overhaul ( EIP-3540 ); EIP-3554  proposes to delay the difficulty bomb to  December  .

In addition, the meeting discussed the test of time to upgrade network for London, Ropsten  scheduled to be highly Block  10399301 6  Yue  9  Ri), Goerli  scheduled to be highly block  4979794 6  Yue  16  Ri), Rinkeby  is scheduled to block highly  8,813,188 6  May  23  May), the main network is still scheduled for  7  May  14  Ri upgrade, after the first successful test network bifurcation, and then determine the main network client upgrade block.

About the difficulty of computing the bomb was delayed by the Square Ethernet core developers  James Hancock  raised . “The difficulty bomb has always been there. We just dialed its  blocktime  back a bit to temporarily’dismantle’ the bomb,” Hancock  told  Decrypt . He proposed to postpone the bomb by  970,000  blocks.

Ethereum core developer Tim Beiko told Decrypt that the developer rejected the proposal to postpone the difficulty bomb until next spring. He said it was unnecessary.

Ethereum developers expect that by  December  , the network will be updated to allow  Ethereum 1.0 a network that relies on  PoW ) to communicate with  Ethereum  2.0 a new network that relies on  PoS  ). This is the so-called merge ( Merge ).

“If the  merger is completed before December  , we don’t need to take any action on the difficulty bomb because we will completely abandon mining.” Beiko  added.

If the merger plan is still not implemented, the Shanghai fork of Ethereum is expected to take place in  October  , which will once again postpone the launch of the difficulty bomb.
