A blockchain-based system for voluntary wealth redistribution.

Components:

• Attestation of humanity: authorities that cryptographically attest that a given person is (within their system) a unique human being, not otherwise represented.
• Ability to publicly or anonymous donate to all people that meet a particular proof of humanness, e.g. every human attested by a state's vital records division
• Ability to publicly (or anonymously?) subscribe to receive donations
• Ability to pledge certain amount and frequency of donations in the future
