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

Need to allow distributed proof of humanness.

Various "humanity" authorities will make their own attestations.

Their attestations can be compared as well, i.e. they accept what another has rejected or vice versa

The first N times an assessment is made, the parties involved get a reward.

Or, the parties involved always get a reward, which declines according to a function, reflecting the diminishing returns involved.

(Could this reward be determined by a market?)

The reward mechanism implies that this is a currency.

The reward is the same for confirmations and rejections.

A high rate of rejection disincentivizes people to use the authority.

Confirmations can be annotated with useful information like genetic hashes and whatnot

(Closed or open vocabulary for annotations?)

Authorities can also attest to each other.

(Are authorities people?)

Like Web of Trust but with a financial incentive to get it right---hopefully. Or to do it at all.

Authorities (and people in general?) can publish contact information, allowing them to be investigated and their trust level increased.

I want there to simply be a "donate(amount)" function that equally distributes the amount to all humans on the system.

But that implies a default set of nodes that are valid.

You pick one or more "trust roots" (authorities) whose judgements you accept.

And you pick a minimum number of confirmations (default 2?) and maximum number of rejections (default 0)

Because received donations will be very small fractions, precision issues would easily arise. Donate 0.001 to a hundred million people and you start to see precision problems.
