Project Eclipse (eclipse)

Bridging ecosystems by storing Zero-knowledge proofs of Solana votes on the Aleo blockchain.

Aleo is a toolkit for private computation that utilizes zero-knowledge proofs stored on a blockchain.

Solana is a blockchain based on a distributing voting system for validation.

By storing periodic zero-knowledge proofs of the Solana votes on the Aleo blockchain, it is possible to create a two-way bridge between Solana, Aleo, and potentially any other system that is able to verify the proofs.

Install

Eclipse is written in Rust, and therefore uses the Rust toolchain.

To Run Aleo-to-Solana

Solana Node

We need to compile the Eclipse version of the Solana Node. For PoC purpose, the easiest way is to compile the Solana-test-validator binary. In our Solana forked repository root, run

./scripts/cargo-install-all.sh .

Then you can run the Solana-test-validator by

./bin/solana-test-validator -r --log

Details found here on the solana-test-validator.

Note: help trace by setting flag:

export RUST_LOG=solana_runtime::system_instruction_processor=trace,solana_runtime::message_processor=trace,solana_bpf_loader=trace,solana_rbpf=trace

Onchain Programs

Now compile the on-chain programs. Under the /programs/aleo-verifier and /programs/uploader by cargo build-bpf --sdk=<path to solana>/sdk/bpf. This will output files in /target/deploy/eclipse_aleo_verifier.so and /target/deploy/eclipse_uploader.so

Then use the previously compiled Eclipse version of the solana binary to deploy the program. In the Solana repository:

./bin/solana program deploy <path-to-the-eclipse_aleo_verifier.so>
./bin/solana program deploy <path-to-the-eclipse_uploader.so>

Take a note of the program-id logged here for next step.

Eclipse Service

Run eclipse service by

$ git clone https://github.com/eqlabs/eclipse && cd eclipse/service/src/aleo-to-solana
$ cargo build // tested on 1.61.0 nightly
$ ./target/debug/aleo-to-solana \
--author_keypair <default-path-to-solana-test-verifier-config-keypair> \
--payer_keypair <default-path-to-solana-test-verifier-config-keypair> \
verify_proofs \
--uploader_program_id <eclipse-onchain-uploader-program-id> \
--verifier_program_id <eclipse-onchain-aleo-verifier-program-id>

This will run the eclipse service continuously. We have printed out where the verification results are stored, take a note of it for the next step.

Checking

You can check if an Aleo tx has been verified by using the Eclipse version of the solana binary. In the Solana repository:

./bin/solana account <account-where-verification-results-stored>
