sybil-resistant faucet

[brenzi]

Thanks to its personhood protocol and XCM, Encointer can host a faucet on its parachain which is resilient to sybil attacks

High-Level Specification

Anyone can launch a new faucet on the encointer parachain and fill the faucet with any token which is transferrable through XCM

Members from whitelisted communities may drip the faucet using their personhood reputation (one cycle attendance allows to drip the faucet once

Faucet vs. Airdrop

I suggest to call this service a faucet, not an airdrop tool. The reasoning is that a faucet requires the beneficiary to take action while an airdrop is passive (One can not prevent to be targeted by an airdrop)

Cash transfer

An NGO could use such fauets to transfer humanitarian aid in stablecoins directly to personhood-verified individuals from selected communities

Security implications

Faucets are an additional incentive to launch Encointer communities and participate. This means it can also incentivises launching bot communities (which would be otherwise worthless as the newly created local currency would have no value in a bot community). That's why we need to establish a web of trust among Encointer communities to decide who can use the faucet. As a preliminary measure, we shall use whitelisting per faucet. The faucet creator can select Encointer communities which are eligible to use the faucet
