This document is a guide to participating in Multi-party Computation(MPC) phase 2 and verifying the result.
-
Send an email to [email protected] to apply to participate in MPC. Please introduce yourself in the email and tell us your available time.
-
TRON will send you an email about the time for you to participate in MPC.
-
When it is your turn, TRON will send you a notification email and give you a params file link which you will need to download.
-
Download the
params
file on server. Minimum requirements of server requires:
- Processor (CPU): Intel Core i5 (sixth generation or newer) or equivalent
- Operating System: Linux (Recommended) / macOS / Windows 7+
- Memory: 8 GB RAM
- Storage: 500 GB internal storage drive
-
Download and install IM tool keybase. If you don't have an account yet, create an account and add TRON' account as your friends. TRON's account is
tron_brown
. -
Run the following code in your terminal to download Rustup and install Rust, then follow the instructions if you are running on macOS / Linux / another Unix-like OS:
# curl https://sh.rustup.rs -sSf | sh
If you are running on windows, please go to rust homepage for installation instruction. In linux, you may need to run as prompted after installation:
# source $HOME/.cargo/env
- Obtain the source code of project tron-mpc-testnet:
# git clone https://github.com/tronprotocol/tron-mpc-testnet
If git has not been installed on your computer, please refer to git first.
- Put
params
file in the tron-mpc-testnet directory, then run:
# cargo run --release --bin compute
When it’s finished, you will get a new_params
file and a hash
which you will need to memorize. You can find the hash
and new_params
as shown below:
Notice: this process could take 0.5 ~ 1 hours according to your hardware capacity and occupy 1.5 ~ 2GB of memory.
- Send your result to TRON. Send the file
new_params
by keybase andhash
by email. Feel free to state your os version in email. E.g. windows 7/centos 7.
We reuse the phase 2 result of zcash https://download.z.cash/sapling-mpc/params as the first params
of the process. At the end of process, we generate the random beacon by using one Bitcoin block's hash as the seed of pseudo random number generator; The block's height will not be determined until last participant completes his operation. After we verify all participants' contribution, we will publish all hash on project wiki page. Anyone can do this verification as belows.
After all participants finish the process, we will announce final params at aws. Following as below to verify your contribution:
# cd tron-mpc-testnet
# wget https://mpcfilepub.s3.amazonaws.com/tron-mpc-testnet/params
# wget https://mpcfilepub.s3.amazonaws.com/powersoftau/powersoftau_phase1_files.tar
# tar xvf powersoftau_phase1_files.tar && cp powersoftau_phase1_files/* .
# cargo run --release --features="verification" --bin verify
This verification may take about 1 hour and then output all participants' contribution. Find whether your hash is in the list.
