About Ethereum’s Arrow Glacier upgrade and difficulty bomb

The Ethereum team has been working hard to make the vision of ETH 2.0 a reality, but things are a bit delayed and may not be fully launched until mid-2022. In order to compensate for the delay and migrate from proof of work to proof of stake, Ethereum proposed an upgrade to the Arrow Glacier network on December 8, 2021, which will help them achieve their target difficulty bomb by June 2022.

So what is this new Glacie update about, what is this controversial difficulty bomb, this is what we are going to explore today.

What is Arrow Glacier network upgrade?

The official Ethereum blog mentions:

In other words, the Ethereum network will be upgraded in the block numbered 13773000, and will be upgraded on Wednesday, December 8, 2021. The exact date may change due to different block times and time zones.

Let us understand the importance of this announcement.

This upgrade is the third upgrade after the most recent 2021 upgrade

  • Altair, upgraded to beacon chain on October 27th.
  • The Muir Glacier upgrade takes place in January 2021
  • There is also the famous London hard fork, which took place in August 2021, where the deflationary EIP-1559 protocol was introduced.

The latest Arrow Glacier network upgrades, such as Muir Glacier, will modify the parameters of the Ice Age/Difficulty Bomb, thereby delaying it for a few months. This change will carry out network upgrades in Byzantium, Constantinople and London. Arrow Glacier did not introduce other changes.

The idea is to push the difficulty bomb until next summer to prevent the chain from freezing, which is the “Ice Age”.

In order to further understand the role of delayed injection, we need to understand the concept behind the difficulty bomb.

What is a difficulty bomb?

The difficulty bomb is just a set of codes added to the main Ethereum blockchain to exponentially increase the difficulty level of mining, which will make it difficult for miners to keep up. It aims to increase the block time, which will eventually lead to the freezing of the blockchain.

The difficulty bomb is a very “steep” exponential curve; it is flat for a long period of time, and then acts quickly when the bomb “explodes”.

The bomb only affects the proof-of-work network, so it only exists on the Ethereum mainnet and the Ropsten test network.

Why was the difficulty bomb introduced in the first place?

The idea of ​​introducing difficulty in the Ethereum proof-of-work main chain is to facilitate the transition to proof-of-stake over a period of time. It further adds an additional attribute to force existing miners to upgrade their nodes.

Therefore, the core goal is to make it difficult for existing miners to stay on the old proof-of-work chain.

EIP 4345:

The current Arrow Glacier upgrade further uses a difficulty bomb, represented by EIP-4345:

What is EIP 4345?

Delay the difficulty bomb until June 2022. This EIP proposal puts the difficulty bomb later than the actual number of blocks of 10,700,000 blocks.

To summarize the difficulty bomb and Arrow Glacier upgrade:

This upgrade is intended to facilitate the migration of ETH miners to the new proof-of-stake chain, and the current ETH network will migrate to ETH 2.0. Ethereum is being severely challenged by existing L1 and hierarchical blockchain platforms, such as Polygon, Solana, Avalanche, Binance Smart Chain. These platforms are much better in terms of speed and scalability, and also in terms of user base. Catch up quickly.

The more the process of Ethereum 2.0 is delayed, the harder it is for Ethereum to maintain its current dominance. Let us hope that by the middle of 2022, Ethereum will fully switch to supporting the proof-of-stake network.
