Human Protocol’s bounty program is the easiest way to get a job working with us. Most of our development comes from the founders of hmt-escrow, bounties from open source developers, or developers hired from the bounty program. Take a look at our issues or suggest a new one, and a mod will add it to the bounty program. Read the documentation as it contains information for working with us.
Reward sizes are guided by the rules below and payable in USDC. If you prefer, you may also elect to have your reward donated to a registered charity of your choice that accepts online donations, subject to approval of the charity.

You need few essential system requirements to successfully install our Python 3 package.
Rightly or Wrongly we tried to use doctests for the vast majority of testing in this project . As a result you may have to remove the raise_on_error=True in the module you are testing to get good feedback on what's broken.
We'd recommend you checking out the dockerfile for an explanation of what applications are required
After that the following command should install the package successfully:
pip install git+https://github.com/iamdefinitelyahuman/py-solc-x@master#egg=py-solc-x \
git+https://github.com/ethereum/trinity@master#egg=trinity \
git+https://github.com/sphinx-doc/sphinx@master#egg=sphinx
pip install hmt-escrow
In order to build the image you need Docker installed on your computer.
We have gathered relevant commands in the bin/ folder.
You can run the project with bin/prelaunch.
Creating a new HUMAN Protocol Job requires a manifest and credentials at minimum. Optionally a factory address and/or an escrow address can be given. Using an existing factory address can be used to deploy a new Job to the Ethereum network. Using an existing factory address and escrow address together an existing Job on the Ethereum network can be accessed. Creating a Job without a factory address deploys a fresh factory to the Ethereum network.
A Manifest has to follow the specification at https://github.com/hCaptcha/hmt-basemodels
Credentials must follow the following format:
>>> credentials = {
... "gas_payer": "0x1413862C2B7054CDbfdc181B83962CB0FC11fD92",
... "gas_payer_priv": "28e516f1e2f99e96a48a23cea1f94ee5f073403a1c68e818263f0eb898f1c8e5"
... }
>>> rep_oracle_pub_key = b"2dbc2c2c86052702e7c219339514b2e8bd4687ba1236c478ad41b43330b08488c12c8c1797aa181f3a4596a1bd8a0c18344ea44d6655f61fa73e56e743f79e0d"
Using only the Manifest and Credentials deploys a new factory to the Ethereum network with the public key of a known Reputation Oracle.
>>> job = Job(credentials, manifest)
>>> job.launch(rep_oracle_pub_key)
True
Providing an existing factory address is done via the Job's class attributes.
>>> factory_addr = deploy_factory(**credentials)
>>> job = Job(credentials, manifest, factory_addr)
>>> job.launch(rep_oracle_pub_key)
True
You can supply an existing escrow factory address when instantiating the class, which it will use to do all operations. If an escrow factory address is not given, it creates one.
Credentials have to contain the private key that was used to upload the previously deployed manifest to IPFS. The Job is instantiated with the fetched manifest.
>>> credentials = {
... "gas_payer": "0x1413862C2B7054CDbfdc181B83962CB0FC11fD92",
... "gas_payer_priv": "28e516f1e2f99e96a48a23cea1f94ee5f073403a1c68e818263f0eb898f1c8e5",
... "rep_oracle_priv_key": b"28e516f1e2f99e96a48a23cea1f94ee5f073403a1c68e818263f0eb898f1c8e5"
... }
>>> factory_addr = deploy_factory(**credentials)
>>> escrow_addr = job.job_contract.address
If you provide an escrow_addr and a factory_addr the library will check
whether that escrow_addr belongs to the factory_addr. If that succeeds
you can continue from the state the contract is in.
A Job can only be launched once: calling launch() will return False if
you previously launched it.
>>> accessed_job = Job(credentials=credentials, factory_addr=factory_addr, escrow_addr=escrow_addr)
>>> accessed_job.launch(rep_oracle_pub_key)
False
Calling setup funds the deployed escrow contract and updates its state with data from the manifest.
>>> job.setup()
True
While no payouts have been performed, aborting and canceling a job is still possible.
>>> job.abort()
True
>>> job.cancel()
True
Performing a bulk payout that doesn't fully drain the escrow contract sets the contract to Partial state. It also uploads the final results from the Reputation Oracle to the contract's state.
>>> payouts = [("0x6b7E3C31F34cF38d1DFC1D9A8A59482028395809", Decimal('20.0'))]
>>> job.bulk_payout(payouts, {}, rep_oracle_pub_key)
True
>>> job.status()
<Status.Partial: 3>
Draining the escrow contract fully sets the contract to Paid state.
>>> payouts = [("0x6b7E3C31F34cF38d1DFC1D9A8A59482028395809", Decimal('80.0'))]
>>> job.bulk_payout(payouts, {}, rep_oracle_pub_key)
True
>>> job.status()
<Status.Paid: 4>
Completing the job sets a Paid contract to complete.
>>> job.complete()
True
>>> job.status()
<Status.Partial: 5>
A build will automatically be deployed to PyPi from master if tagged with a version number. This version number should match the version in the setup.py file.
The tags will need to be pushed to master via a user that has the proper privileges (see the contributors of this repo).
Versioning should follow the semver versioning methodology and not introduce breaking changes on minor or patch-level changes.

The HUMAN Protocol token contract (HMToken.sol) has been audited by several third parties, most recently CertiK. You can see the results of this audit in the audits directory. The code for this contract is stable and not expected to change materially in the future.
The escrow factory and related code are under active development, and escrow factories on the testnet are frequently launched during development.
Although all code goes through internal reviews before being committed, you should assume the current code in master has not been externally audited to the same degree as the token contract.
When a stable 1.0 version of the escrow factory contract is released, this section of the README will be updated with a link to audit results for that githash.
The docker-compose.yml references a default minio username and password for development. minio as used here is an internal cache for low-privilege, publicly readable, encrypted data. Including these default credentials for development is intentional.
When deploying to a production environment you are expected to set your own credentials based on the rules applied to minio access within your cluster.
