Where is the upgrade focus of Ethereum Arrow Glacier?

November 11 message, the Ethernet Square Arrow Glacier (ArrowGlacier) network upgrade will block height of 13.773 million (about December 8) were at, in order to upgrade the Ethernet node to be Square before December 5 Upgrade the node to take into account the possible change of block time.

On November 9, the Ethereum client Geth has released a new version v1.10.12, which already includes technical updates related to the Arrow Glacier hard fork upgrade. The new version of Geth also supports a new PoW testnet called Sepolia, which was conceived during the merger and interoperability in Athens, with the purpose of replacing Ropsten as the main cross-client testnet after the merger.

Arrow Glacier is a network upgrade similar to Muir Glacier. It only includes one EIP-4345: postpone the difficulty bomb until next summer to prevent the blockchain from freezing, which is the “ice age”. This means that after the upgrade of the arrow-shaped glacier, the difficulty bomb will be postponed to June next year.

EIP-4345 proposes to push the difficulty bomb back by 10,700,000 blocks from the actual block height, which is delayed from the last time, that is, the London upgrade adds 1,000,000 blocks.

Previously, Tim Beiko proposed on October 5 that EIP should be postponed by 10,500,000 blocks, approximately in May 2022. However, following further discussions at the Ethereum core developer conference, it was decided to push the bomb to next summer. The main factor is the merger and upgrade of the Ethereum chain. Only the merger of the Ethereum chain can be successfully carried out, and the subsequent operation of the Ethereum chain can be carried out in an orderly manner.

The difficulty bomb is used to double the mining difficulty level, making it difficult for miners to keep up with the new difficulty, and the block generation time will increase, which will eventually cause the blockchain to fail to run until it freezes. The two ends of the entire transition process are the PoW chain and the PoS chain. After the difficulty bomb is implemented, Ethereum will completely become the proof-of-stake chain.

In order to develop from PoW to PoS, Ethereum has gone through a long upgrade process (see below). This process led to the overall change of Ethereum miners.

2015.11: “EIP-2: Homeland Hard Fork Changes”

2016.4: “EIP-100: Modify the difficulty adjustment for the average block time including uncle blocks”

2016.6: “EIP-649: Metropolitan Difficulty Bomb Delay and Block Reward Reduction”

2018.7: “EIP-1234: Constantinople difficulty bomb delay and block reward adjustment”

2019.11: “EIP-2384: Muir Glacier Difficulty Bomb Delay”

2021.5: “EIP-3554: Difficulty Bomb Delayed to December 2021”

2021.10: “EIP-4345: Difficulty Bomb Delayed to June 2022”

Why is progress so long and difficult?

The reason is that the Ethereum chain is based on a decentralized community. Today’s huge sum of computing power is the biggest guarantee to support the operation of Ethereum. The growth process of Ethereum’s computing power is attracted through mining incentives. The ecology of mining is an economic model of hardware input and output. Ethereum also needs these huge computing power to turn to support PoS chains. In other words, let the computing power be launched in an orderly manner, and the computing power will not change before the Ethereum PoS chain undertakes the main block production, which will affect the security of the chain.
