• zkOracle implementation repo
• HyperLane deployment repo

Dependencies

• Hardhat
• nodejs >= 16.0
• Ganache CLI

Clone

git clone git@github.com:NilFoundation/mina-state-proof.git
cd mina-state-proof

Install dependency packages

npm i

Compile contracts

npx hardhat compile

Test

npx hardhat test #Execute tests
REPORT_GAS=true npx hardhat test # Test with gas reporting

Deploy

Launch ganache using the following

ganache-cli -l 900000000 -m 'test test test test test test test test test test test junk' -g 20000 --verbose

To deploy to test environment (ex: Ganache)

npx hardhat deploy  --network ganache 

Hardhat re-uses old deployments, to force re-deploy add the --reset flag above

Usage

Below are two tasks that execute flows to validate the ledger state and validate the account state. Please note, these work against the above deployment, hence, you must run the deployment before executing the following.

Validate Ledger State

npx hardhat validate_ledger_state --proof ./test/data/proof_v.data \ 
--ledger jwYPLbRQa4X86tSJs1aTzusf3TNdVTj58oyWJQB132sEGUtKHcB \  
--network ganache

Inputs

• proof : File path with the full Mina ledger state proof retrieved from proof market.
• ledger: This is the hash of the ledger which this proof attests.
• network: Network to run this task against.

Validate Account State

npx hardhat validate_account_state --proof dummyFlag \  
--state ./examples/data/account_data.json \
--ledger jwYPLbRQa4X86tSJs1aTzusf3TNdVTj58oyWJQB132sEGUtKHcB \ 
--network ganache

Inputs

• proof : File path of the account state proof retrieved from the proof market.
• state : File path of the account state which the above proof attests to.
• ledger: Hash of the ledger against which the account state is validated.
• network: Network to run this task against.

Account state file structure

{
  "public_key" : public key of zkApp/User Account,
  "balance" : {
    "liquid" : Unlocked balance in MINA  ,
    "locked" : Locked/Staked balance in MINA 
  },
  "state": 8 byte state of zkApp/user account
}

See examples/data/account_data.json for examples.
