Re: [ANN] *Aborted* Bitcoin Resilience: Cuckoo Cycle PoW Bitcoin Hardfork

Dev maybe you will relaunch your project later? You have a nice idea which can solve many problems of BTC.

If in the future the miners once again try to takeover Bitcoin with a hardfork we'll be ready.
But otherwise we wouldn't want to hardfork Bitcoin for no reason, one of our core principles is not to disrupt the core chain needlessly.

Due to the peaceful cancellation of segwit2x we're aborting this project for now with mixed emotions
should the miners once again become a problem we will be ready to re-launch.

thanks you everyone for your support
today was a great victory for Bitcoin Smiley

So.. is there any pools and compiled miners for this testnet?

source code for working pool and miner are linked in the OP
a public mining pool is being set up for testnet and mainnet, stay tuned for updates
a windows binary for the miner is also in the works

I've asked twice about working, compiled stuff for mining before the start, but looks like i'm ignored.

you weren't ignored
there will be compiled stuff before the start, which is in 10 days
we are now in public testnet phase aimed at devs, and the mainnet version hasn't been released yet

In which country this will be working? This will be for limited countries?

in any country where bitcoin works Smiley

Wow! Is it really cuckoo cycle implementation? It's great algo with asic resistant and botnet resistant. I'm in.

You can help by spreading the word on social media!  Smiley

it's a bitcoin hardfork, we only changed the PoW algorithm

You'll need to change the difficulty as well.
And possibly the difficulty adjustment, since rapid hashpower fluctuations are to be expected.

You are correct, and we have.
The mining difficulty will be reset when the PoW changes, and emergency retarget has been also been implemented
that's what is written in the OP as well.
i was answering a comment about block time and rewards and didn't realize i was making too general of a statement.
The core principle is to only change what needs to be changed

DEV, what about total coin supply? 21m like simple Bitcoin?
Block time?
Block reward?

it's a bitcoin hardfork, we only changed the PoW algorithm

As explained in the OP, the value comes from the fact that the current bitcoin miners have been actively holding back progress for years and are now openly talking about killing the existing chain with a few ideas on the table about just how they could do it

Bitcoin Resilience

Update: Project Aborted! (for now)
Due to the peaceful cancellation of segwit2x we're aborting this project for now with mixed emotions
should the miners once again become a problem we will be ready to re-launch.

Background

In recent months it has become self-evident that bitcoin mining is extremely centralized.
While the greater community shows almost no interest in the 2X fork, the threat of using said
centralized hashrate to disrupt the core chain to the benefit of 2X or BCash for a long period of time remains real.

An ASIC resistant PoW alternative where ASIC miners are not able to slow down progress must be available for the community.
(And Equihash forks with premine and consensus rules changes are clearly not it, sorry)


Cuckoo Cycle

We've picked the most ASIC resistant algorithm we could find:
https://github.com/tromp/cuckoo


Commitment to zero disruption to core chain

  • We will fork on the same block as 2X does. This serves a double purpose:
     1. Services are already suspending activities because of the 2X fork
     2. If the core chain is attacked (reorg, wipeout, double spends, …), this is the time to offer the alternative
  • "Magic bytes" are changed so Resilience nodes will not connect to core nodes


Details

Algorithm: Cuckoo Cycle: 42-cycle with a graph size of 2^30 (2^20 on testnet)
Premine: No.
Added Difficulty retarget: Emergency only
Two-Way Replay Protection: Yes
Intended for GPU mining.
