Create signer bin

git clone https://gitlab.com/unit410/tendermint-validator

cd tendermint-validator

git checkout e4a1fa93e05681e9aa4e8419795d1f268e06b049

go mod tidy

env GOOS=linux GOARCH=amd64 make build

copy binary to this Repository <project-dir>/signer/bin

example:

cp tendermint-validator/build/* tendermint-mpc-test/signer/bin

Create validator bin

git clone https://github.com/CosmosContracts/juno

cd juno

git checkout e507450f2e20aa4017e046bd24a7d8f1d3ca437a

env GOOS=linux GOARCH=amd64 make build

example:

cp juno/bin/junod tendermint-mpc-test/validator/bin

Build validator image

in this project dir:

docker build -t validator:v0.0.1 validator --no-cache

Run validator image locally (optional)

docker run --env-file envval.list validator:v0.0.1

Create shares

key2shares --total 3 --threshold 2 priv_validator_key.json (or other location of priv_validator_key.json)

rename private_share_1.json to share.json and copy to <this-project-dir/signer/config/shares/1/share.json> rename private_share_2.json to share.json and copy to <this-project-dir/signer/config/shares/2/share.json> rename private_share_3.json to share.json and copy to <this-project-dir/signer/config/shares/3/share.json>

Build signer image

in this project dir:

docker build -t signer:v0.0.1 signer --no-cache

Run signer image locally (optional)

docker run --env-file envsigner.list signer:v0.0.1

Important information

docker-compose file tries to attach your lokal ~/.juno and ~/.juno2 (second val) folder to start at synced blocked height (you should store this chaindata there)

to create ~/.juno2 with chain data. You can copy ~/.juno files to ~/.juno2 cp -R ~/.juno ~/.juno2 (please stop your local daemon before copy)

if you want to use data in validator image for ~/.juno and ~/.juno2 set OVERWRITE=1 for both validators in docker-compose.yml. (pay attention. this overwrites data in ~/.juno and ~/.juno2 with the data in validator/config (docker image) and starts syncing around Block 0)

Start docker-compose

docker-compose up

cmds

docker logs tendermint-mpc-test-validator1-1 -f

docker logs tendermint-mpc-test-validator2-1 -f


docker logs tendermint-mpc-test-signer1-1 -f

docker logs tendermint-mpc-test-signer2-1 -f

docker logs tendermint-mpc-test-signer3-1 -f

Watch status

val1:curl localhost:30057/status

val2:curl localhost:30157/status

Check current signer logs for =SIGNED_MSG_TYPE_

in project dir.

docker-compose stop signer1 (or other signer: ex. signer2, signer3)

in this test case I stopped signer1 with "=SIGNED_MSG_TYPE_" logs:

signer3 throws error:

GetEphemeralSecretPart req error and the two remaining signer shows some weird behavior where some blocks are signed and some not.

Expected behaviour: 100% signing
