1 minute plot creation time?

[cayolblake]

Hello @madMAx43v3r

What would it take to have one minute plot time?

Is it hypothetically possible? Would it require a GPU for parallel processing?

[alexwwstx]

if it's possible, I don't think the current Chia algorithm will not be changed

How/Why so?

Simply because plotting speed is just one of the many requirements to win a block.

I'm talking about plot-creation-time.

Unless, you are talking about realtime plot creation will in-theory defy the practicality of using Chia blockchain as a whole, however, we're talking 1 minutes versus 30 seconds.

Let's say I'm asking about 10 minutes, not one :)

Managed to get mine down to just over 25 minutes, will be trying a 24C CPU over the next few days, the following was on a Xeon 6226R 16 Core / 32T CPU, 64GB RAM, 2x Intel P5800X 800GB in a VROC RAID0, number of buckets for all phases was 256 as I have noticed that you get better performance due to the smaller block I/O size versus 128 buckets
