Plotting speed and security in Chia
With the release of the MadMax plotter there has been a lot of confusion about what improved plotting speeds mean to the security of the Chia blockchain.
Bram, Gene, and the team will be available to talk about how improved plotting speed is great, what the actual security considerations for the Chia blockchain are, and the kinds of changes that can be made in the future to make sure plotting and farming remain secure. Hint: Your k32’s are going to be fine.
We will be sticking to plotting, plotting speed, and security so questions around the official pooling protocol will be passed over. We will have more on the official pooling protocol in a subsequent Zoom soon.
00:00 - Technical difficulties, skip
4:43 - Beginning
5:28 - Quick high-level introduction
7:12 - Presentation start
9:38 - What are the most significant differences between new plotters and official Chia's plotter?
14:12 - Will you be retiring k32 anytime soon?
14:52 - Replotting or "Real-Time Plotting" explanation (PoW substitution to PoST)
18:23 - Can plotting be done on GPUs?
19:59 - What are hardware limiting factors for real-time plotting?
22:39 - Is 2 TB/s memory bandwidth fast enough for real-time plotting?
23:22 - Cost of mining (PoW) vs. farming (PoST)
33:54 - What will you do if the situation changes in the future and becomes more cost-effective to generate plots in real-time?
36:50 - Is MadMax significantly less effective for the same k32?
40:19 - Will you integrate the MadMax plotter into the official Chia code?
41:27 - Does the MadMax plotter pass the plot filter as often as official Chia plots?
42:43 - Will new pool compatible plots work on different chains?
48:18 - What are your thoughts on the transition to k33? Are there any advantages of replotting to k33 instead of k32?
49:46 - Is it easy for people developing community plotters to include plot format changes into their code?
50:52 - Is Chia quantum resistant? Where are possible vulnerabilities?
54:22 - Can we keep using current plots when pool plots are available?
54:31 - If I join a pool, can I go back to solo farming?
55:41 - If you would have to change a filter, would it be a fork?
56:10 - Is there chia plots check command for the MadMax plotter?
58:21 - Is double farming a concern?
1:01:28 - Could somebody try to use FPGA or ASIC with high-speed memory to create phase 1 of a plot faster than a GPU?
