Ethereum Classic to Remove the Difficulty Bomb via Fork

Difficulty Bomb will be removed from Ethereum Classic Mainnet at block 5,900,000 in order to avoid collapse of the network

Ethereum Classic, a continuation of the original Ethereum blockchain, is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third party interference.

This ECIP new monetary policy of Ethereum Classic proposes removing Difficulty Bomb from Ethereum Classic Mainnet at block 5,900,000 in order to avoid collapse of the network. The growing Difficulty Bomb above 20% of standard difficulty is dangerous, and the latest safe block to enable new hardfork would be 6,100,000 with 550Gh of extra difficulty. Although considering the hardfork boundaries proposed by Ethereum Classic developers, block 5,900,000 was chosen for the hardfork.

Block 5,900,000 is expected in May 2018 and will require 137Gh of additional difficulty. It’s an optimal block under current circumstances. It is worth noting that there will be no "free coins" with this fork, as it is a network improvement.

Implementaion:

if (block.number >= diffuse_block) {
    extra_difficulty = 0
} else {
    explosion = PREVIOUS_FORMULA
    extra_difficulty = int(2**explosion) 
}

block_diff = parent_diff 
      + parent_diff / 2048 * max(1 - (block_timestamp - parent_timestamp) / 10, -99) 
      + extra_difficulty

At the moment of press, these are main market parameters of Ethereum Classic:

  • Average price: $13,94 
  • Marketcap: $1 406 839 671
  • 24h volume: $99 729 900

Atlantis Ethereum Classic Hardfork Date Unveiled

It was agreed that the update will take place at block 8,772,000 and it should activate the changes that were proposed for the original ETH network in 2017

During the videoconference on Thursday, June 20, Ethereum Classic developers came to an uneasy consensus on hardfork of a network called Atlantis, CoinDesk reports.

Despite certain differences, it was agreed that the update will take place at block 8,772,000. As expected, it will be found around 12:00 UTC on September 17 of this year.

In May, ETC developers disagreed on what improvements the upcoming hardfork should contain, but last Thursday they nevertheless found a consensus on the 10 proposals that should be included in the code of the future hardfork.

It is noteworthy that earlier in June, the developers agreed to launch Atlantis hardfork in the test network by the end of this month, while the launch of the code in the main network was to take place before the end of the summer.

However, a little earlier, Ethereum Classic Labs, the developer of the most popular client of the Classic Network Geth, insisted on activating hardfork on July 1. This decision was allegedly made under pressure from miners and exchanges based in Asia, which insisted on the fastest possible changes in the network.

At the beginning of the month about this was told by the Asian community manager Ethereum Classic Cooperative Christian Xu. However, a number of community representatives, including the founders of the research startup Gödel Labs Tang and Roy Zhou, accused Xu of falsifying such allegations.

We asked them about Atlantis. We got the normal ‘don’t care’ response. But several exchanges/miners also said that they’re not aware of this before. That makes me feel suspicious.

Passion was flared by the position of Ethereum Classic Labs and its CEO Terry Culver, who initially opposed the postponement of the hardfork to a later date.

I strongly disagree. We can’t subscribe to that schedule. We stick to the schedule that we originally agreed upon.

CEO, Ethereum Classic Labs

Nevertheless, over the past few days, the position of Ethereum Classic Labs has changed towards a wider dialogue with the rest of the developer community. On Wednesday, the blog Ethereum Classic Labs posted an entry confirming these intentions and a new roadmap regarding hardfork.

The Atlantis update is paired with a slightly later upgrade called Agharta and should activate the changes that were formally proposed for the original Ethereum network in 2017. Their goal is to improve interoperability between the two blockchains and facilitate the migration of decentralized applications (dApps) from one network to another.
