Retroactive Public Goods Funding

Discussion

By Vitalik Buterin:

"The core principle behind the concept of retroactive public goods funding is simple: it’s easier to agree on what was useful than what will be useful. The former is still often a source of disagreement, but it’s a type of disagreement where you could still get reasonably good top-level judgements by using some existing voting mechanism (eg. quadratic voting or even regular voting). The latter is much more challenging. For the profit-making sector, the best that we can do is to build out an ecosystem where people can create startups and invest in them, and get rewarded if they end up correct. So rather than reinventing the wheel entirely, we will create a public-goods-oriented version of the exact same mechanism.

A DAO, which we can call “the Results Oracle”, funds public good projects. Long term, the results oracle can be funded by protocol fee."
