MootVote

MootVote is an anonymous bribery-resistant voting platform, powered by zk-SNARKs and Solana.

compiling the circuits

For things to work, replace Poseidon with PoseidonHasher in node_modules/.pnpm/circomlib@2.0.5/node_modules/circomlib/circuits/smt/smthash_poseidon.circom and remove ../poseidon.circom import. Then:

pnpm install

pnpm circomkit compile Vote && pnpm circomkit setup Vote
pnpm circomkit compile Tally && pnpm circomkit setup Tally
pnpm circomkit compile Relay && pnpm circomkit setup Relay

Export verifying key to put in programs/mootvote/src/vk.rs and programs/zk-relayer/src/vk.rs:

pnpm exportVk

testing

anchor test

or with the indexer:

anchor build
solana-test-validator \
  --reset \
  --warp-slot 32 \
  --deactivate-feature 9LZdXeKGeBV6hRLdxS1rHbHoEUsKqesCC2ZAPTPKJAbK \
  --bpf-program target/deploy/mootvote-keypair.json target/deploy/mootvote.so \
  --bpf-program target/deploy/zk_relayer-keypair.json target/deploy/zk_relayer.so

cargo run --package mootvote-indexer -- --config indexer/config.yml

anchor test --skip-local-validator --skip-deploy

compiling relayer backend

mkdir build/Relay/Relay_cpp/cpp_dat
cp build/Relay/Relay_cpp/Relay.* build/Relay/Relay_cpp/cpp_dat/
cd relayer
cargo build --release

testing over nginx

There is an HMR-compatible nginx configuration at nginx/dev/nginx.conf ready to be put to /etc/nginx/nginx.conf. Then launch nginx and the services:

cd frontend
pnpm dev

cd indexer
cargo run -- --config config.yml

cd census-service
cargo run -- --config config.yml

cd relayer
RELAYER_SOLANA_KEYPAIR=YOURKEYPAIRBASE58 cargo run -- --config config.yml

And proceed to http://127.0.0.1.
