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
