Title: What coins have successfully changed their mining algorithm? Post by: CoinFascination on June 30, 2019, 02:45:58 PM My question is about coins that have changed their algorithm midstream, they had one and then changed.
Not necessarily from POW to POS, but from one type of POW to another. In the case of the neoscrypt, that is of interest because of the varying block times. Changing the algo programatically seems easy, but coordinating with Hodlers and mining pools seems a huge issue. Unless it is not. Trying to find out.

The most popular and recent one I can think of is Monero. They basically use the Cryptonite algo and due to the threat of ASICs and FGPA they had to fork to a slightly different algo about 2-3 times already. First it was the original Cryptonite algo, then Cryptonite V7, Cryptonite V8, and now its Cryptonite R. And from what I read they will change this algo every 6 months or so to defeat ASICS. There are some smaller coins like Bitcoin Gold which switched from Equihash to a different variant of Equihash to make it mineable with GPUs but not with the ASICS which are all over ZEC.

Seems like 4 times a day. Or through 100k blocks... But no pools. Only solo mining on CPU.

So, a block so and so, the algo changes and miners adjust. Seems very simple so I wonder about complications. I wonder about some coins getting stuck, maybe forever.

Whenever there is a forced algo change its usually against the majority of the hashpower interest. So the miner's with ASICs won't want to go with the fork which will change the algo. The only miners which want the fork are the GPU miners so they can make money again. So when this happens its important that all the Services or Exchanges which use that coin update to the newest software with the fork. If they refuse then it creates issues. This happened in the past with Bitcoin. Where there was proposed block size increases but the consensus didn't agree. The coins won't get stuck, they will just get stuck on the minority chain. You will still be able to claim them on the majority chain however. |
