## What is this?

ethdont splits an existing BLS12-381 key using Shamir's secret sharing with a chosen threshold.

Each key share is then imported into a Dirk distributed wallet.

## Build

**Native***

```

make build

```

**Docker**

```

make docker

```

If using the Docker image, run with `docker run --rm -ti -v $(pwd):/data:rw --workdir /data ethdont`

## Run

### Requirements

  * keystore in `keystores/keystore.json`

  * keystore passphrase in `keystores/secret`

```

# Create a random seed for the deterministic key generator

KEYGEN_SEED=$(head -c 32 /dev/urandom | xxd -p -c 32)

DIRK_PEERS="1:dirk1:13141,2:dirk2:13142,3:dirk3:13143"

DIRK_PEER_IDS="$(echo $DIRK_PEERS | awk -F '[,:]' '{for(i=1;i<=NF;i+=3) printf "%s ", $i; print ""}')"

for id in $DIRK_PEER_IDS; do

    ./ethdont \

        -dirk-peers "${DIRK_PEERS}" \

        -keystore keystores/keystore.json \

        -keystore-passphrase "$(cat keystores/secret)" \

        -threshold 2 \

        -wallet DistributedWallet \

        -wallet-passphrase "something secret" \

        -keygen-seed "${KEYGEN_SEED}" \

        -account validator-1 \

        -wallet-base-dir wallets/dirk${id}/wallets/ \

        -dirk-id "${id}"

done

```
