The faucet will in turn deduplicate user requests and send the Ether. After a funding round, the faucet prevents the same user requesting again for a pre-configured amount of time, proportional to the amount of Ether requested. + +## Operation + +The `faucet` is a single binary app (everything included) with all configurations set via command line flags and a few files. + +First thing's first, the `faucet` needs to connect to an Ethereum network, for which it needs the necessary genesis and network infos. Each of the following flags must be set: + +- `--genesis` is a path to a file containin the network `genesis.json` +- `--network` is the devp2p network id used during connection +- `--bootnodes` is a list of `enode://` ids to join the network through + +The `faucet` will use the `les` protocol to join the configured Ethereum network and will store its data in `$HOME/.faucet` (currently not configurable). + +## Funding + +To be able to distribute funds, the `faucet` needs access to an already funded Ethereum account. This can be configured via: + +- `--account.json` is a path to the Ethereum account's JSON key file +- `--account.pass` is a path to a text file with the decryption passphrase + +The faucet is able to distribute various amounts of Ether in exchange for various timeouts. These can be configured via: + +- `--faucet.amount` is the number of Ethers to send by default +- `--faucet.minutes` is the time to wait before allowing a rerequest +- `--faucet.tiers` is the funding tiers to support (x3 time, x2.5 funds) + +## Sybil protection + +To prevent the same user from exhausting funds in a loop, the `faucet` ties requests to social networks and captcha resolvers. + +Captcha protection uses Google's invisible ReCaptcha, thus the `faucet` needs to run on a live domain. The domain needs to be registered in Google's systems to retrieve the captcha API token and secrets. After doing so, captcha protection may be enabled via: + +- `--captcha.token` is the API token for ReCaptcha +- `--captcha.secret` is the API secret for ReCaptcha + +Sybil protection via Twitter requires an API key as of 15th December, 2020. To obtain it, a Twitter user must be upgraded to developer status and a new Twitter App deployed with it. The app's `Bearer` token is required by the faucet to retrieve tweet data: + +- `--twitter.token` is the Bearer token for `v2` API access +- `--twitter.token.v1` is the Bearer token for `v1` API access + +Sybil protection via Facebook uses the website to directly download post data thus does not currently require an API configuration. + +## Miscellaneous + +Beside the above - mostly essential - CLI flags, there are a number that can be used to fine tune the `faucet`'s operation.

invokes `caller`.\n - `caller` invokes `0xaa`. `0xaa` has 3 wei, does a self-destruct-to-self\n - `caller` does a `1 wei` -call to `0xaa`, who thereby has 1 wei (the code in `0xaa` still executed, since the tx is still ongoing, but doesn't redo the selfdestruct, it takes a different path if callvalue is non-zero)\n\n-Tx 2:\n - `sender` does a 5-wei call to 0xaa. No exec (since no code). \n\nIn geth, the result would be that `0xaa` had `6 wei`, whereas OE reported (correctly) `5` wei. Furthermore, in geth, if the second tx was not executed, the `0xaa` would be destructed, resulting in `0 wei`.
