Instructions for a planned ceremony will be posted when everything is tested and finalized.
---
## 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.
