On what can be developed on Ethereum

  • A globally accessible financial system, including payments, store of value, also more advanced stuff like insurance http://hurricaneguard.io/
  • Identity: “sign in with Facebook” -> “sign in with an ethereum account, no intermediaries”. Also web of trust
  • All sorts of registries should publish on chain for security and easy verifiability, see my thread on this https://twitter.com/vitalikbuterin/status/1072158957999771648
  • Experimenting with new forms of human organizational structure, eg. @MolochDAO
  • All sorts of micropayment use cases via payment channels
  • Markets for personal data for privacy preserving machine learning (you pay me X, I let you homomorphically execute function Y on my data that’s been attestated to by Z…)
  • Cryptoeconomics for spam prevention in social networks
  • Cryptoeconomics / micropayment schemes to reward publishers of good content
  • Testing ground for new market designs, eg. frequent batch auctions, combinatorial auctions, automated market makers (eg. http://uniswap.exchange )
  • Stickers/badges
  • p2p marketplace for internet connections / incentivized mesh networks
  • Identity, reputation and credit systems for those that currently have few resources (eg. refugees)
  • Decentralized DNS alternatives (eg. http://ens.domains/ )
