It's really great to see FPGAs making a comeback, and in a way that's more accessible to individual miners.

I have some technical questions, if I may;

It was mentioned in a previous post that the units will come with encryption keys burned in. I'm somewhat familiar with the IP protection mechanisms of previous generation Xilinx devices, so is my understanding correct that these VCU1525's won't load a bitstream unless it's been encrypted using your key?
If the above is true, if for whatever reason you had to cease your operation, or are unable to provide devs with continued access to development hardware, would you release these encryption key(s) and any other secrets to prevent future development work on bitstreams for fielded units grinding to a halt?

Thank you both for all your efforts in this.

Kind regards,
David

Was it answered? It's very important question to my mind...

Yes, the encryption key will not prevent unencrypted designs from being loaded but will prevent other encrypted designs from being loaded. If you ever did want to run some other encrypted design you would be required to blow the fuse and the same restrictions would be in place. But, for instance, whitefire's unencrypted designs will work just fine.
