Bitcoin ABC proposes the hard fork of November to stabilize the difficulty of Bitcoin cash extraction

Bitcoin ABC has proposed a hard range of the Bitcoin Cash protocol to fix problems associated with setting up the urgency of cryptocurrency (EDA).

The problem with the EDA Bitcoin Cash

Since Bitcoin Cash moved out of the Bitcoin backbone on August 1, its network has experienced hash fluctuations and blocking times. The reason is that the EDA automatically adjusts based on network conditions to help Bitcoin Cash stay profitable.

However, because miners can easily switch between Bitcoin and Bitcoin Cash – and some mining pools are set up to automatically tap the most profitable chain – they exploit EDA by mining Bitcoin up to what Bitcoin Cash difficulty will collapse and that profitability will increase. Then they transfer a significant amount of hash to Bitcoin Cash, causing blockages almost every minute. Eventually, this triggers another EDA, which makes Bitcoin Cash less profitable for mine, and most of the miners become Bitcoin again, which makes the blocking time at an unreasonable level for a currency that claims to be built for daily transactions. .

Bitcoin Proposal ABC

Bitcoin ABC offers a hard fork that will activate an updated Difficulty Adjustment Algorithm (DAA) based on the D601 algorithm developed by Amaury Sechet of Bitcoin ABC. According to ABC Bitcoin's announcement, the new DAA seeks to achieve the following goals:

  • Adjusts hash rate difficulty to target an average blocking interval of 600 seconds.
  • Avoid abrupt changes in difficulty when the hash rate is fairly stable.
  • Adjust the difficulty quickly when the hash rate changes quickly.
  • Avoid oscillations due to the return between the hashing rate and the difficulty.
  • Be resilient to attacks such as time stamp manipulation.

Bitcoin Classic indicates that the updated software will be available by November 1st and that the hard range will be activated on November 13th.

The classical developer criticizes the proposition

However, although the need to update the DAA is widely accepted within the bitcoin community, Bitcoin ABC has been criticized for this specific proposal. For example, the Bitcoin Classic developer, Tom Zander, did not mince his words on the proposal, claiming in a blog post that he found "very disturbing". Specifically, he objected that the decision to implement the algorithm D601 was a "decision in camera" made for "political" purposes, and not technical efficiency.

On reddit, he accused Bitcoin ABC of using the same tactic to force the new DAA as it would have used to implement EDA in the first place:

"I have not seen any simulation, no response to the criticisms made on the mailinglist, not even a statement of what are the design goals.When the result is to choose your own algo, and to provide no research on why, so we should ask tough questions.I see a repetition of EDA, the same person ignoring comments and making a political move at the last moment. "

"Even Core did better than that," he concluded, referring to the common assertion by bitcoin money advocates that Bitcoin is ruled by an elite group rather than by a decentralized community consensus.
