Blockchain CTF with bounty on steriod 💪

Generate Proof

Change directory to host

cd host

Setup environment, change the value to your desired value.

cp .env.example .env
vim .env

Edit environment and input transactions sequence.

vim src/main.rs

// Modify this line to change the secret
//let mut secret = totally_not_a_backdoor()?;
//secret.submitter = submitter;
//secret
panic!("Please provide a txs path");

Run binary to generate proof. The proof and parameters that is required to claim the bounty will be printed out in stdout.

cargo run --release
# Image ID: ...
# Submitter: ...
# Txs Hash: ...
# Env Hash: ...
# Seal bytes: ...
# Post state digest: ...

Please recheck the Image Id and compare it with contract's PRE_STATE_DIGEST (Or in UI's claim page). If it's different, please rerun with cargo run --release -- --IMAGE_ID={PRE_STATE_DIGEST}

Or optionally, run the binary with --txs-path and --env-path to load the transactions and environment from a file instead. See sanity.txs.json and sanity.env.json for example.

cargo run --release -- --txs-path sanity.txs.json --env-path sanity.env.json
