## To run the ceremony on your laptop:
|
||||
|
||||
1. Preparation:
|
||||
|
||||
```
|
||||
rustup update # tested on rustup 1.17.0
|
||||
cargo build
|
||||
```
|
||||
|
||||
2. Put `response` file from the previous ceremony to root directory.
|
||||
3. To generate `new_challenge` run:
|
||||
|
||||
```
|
||||
cargo run --release --bin verify_transform_constrained # this will generate new_challenge from response file
|
||||
```
|
||||
|
||||
4. Backup old files and replace `challenge` file:
|
||||
|
||||
```
|
||||
mv challenge challenge_old
|
||||
mv response response_old
|
||||
mv new_challenge challenge
|
||||
```
|
||||
|
||||
5. Run ceremony:
|
||||
|
||||
```
|
||||
cargo run --release --bin compute_constrained # generate response file
|
||||
```
|
||||
|
||||
Put your hash from output response to private gist (example: https://gist.github.com/skywinder/c35ab03c66c6b200b33ea2f388a6df89)
|
||||
|
||||
6. Reboot laptop to clean up toxic waste.
|
||||
|
||||
7. Save `response` file and give it to the next participant.
|
||||
|
||||
## Recommendations from original ceremony
|
||||
|
||||
Participants of the ceremony sample some randomness, perform a computation, and then destroy the randomness. **Only one participant needs to do this successfully to ensure the final parameters are secure.** In order to see that this randomness is truly destroyed, participants may take various kinds of precautions:
