> "For a blockchain to be optimally distributed, there must be a so-called Sybil cost. There is currently no known way to implement Sybil costs in a permissionless blockchain like Bitcoin or Ethereum without employing a centralized trusted third party (TTP). Until a mechanism for enforcing Sybil costs without a TTP is discovered, it will be almost impossible for permissionless blockchains to achieve satisfactory decentralization." https://saito.tech/wolves-and-sheep/ https://saito.tech/wolves-and-sheep/
