SSV - Secret Shared Validator

SSV is a protocol for distributing an eth2 validator key between multiple operators governed by a consensus protocol (Istanbul BFT).

⚠️ Phase 1 testing ⚠️

Please see phase 1 testing doc for details

Getting started

# Build binary
$ CGO_ENABLED=1 go build -o ./bin/ssvnode ./cmd/ssvnode/

# Run local 4 node network (requires docker and a .env file as shown below)
$ make docker-debug 

# Lint
$ make lint-prepare

$ make lint

# Full test
$ make full-test

Splitting a key

We split an eth2 BLS validator key into shares via Shamir-Secret-Sharing(SSS) to be used between the SSV nodes.

# Extract Private keys from mnemonic (optional, skip if you have the public/private keys ) 
$ ./bin/ssvnode export-keys --mnemonic={mnemonic} --index={keyIndex}

# Generate threshold keys
$ ./bin/ssvnode create-threshold --count {# of ssv nodes} --private-key {privateKey}

Example .env file

   DISCOVERY_TYPE=mdns
   CONSENSUS_TYPE=validation

   VALIDATOR_PRIVATE_KEY= # NOT USED FOR NOW

Progress

[X] Free standing, reference iBFT Go implementation
[X] SSV specific iBFT implementor
[X] Port POC code to Glang
[ ] Single standing instance running with Prysm's validator client
[\] Networking and discovery
[\] db, persistance and recovery
[ ] Between instance persistence (pevent starting a new instance if previous not decided) [ ] Multi network support (being part of multiple SSV groups)
[X] Key sharing
[X] Deployment
[\] Documentation
[ ] Phase 1 changes
[ ] Audit

** X=done, \=WIP
