The better way is to transition to identity networks. The sybil attack is a function of the low cost of identities. In the current stack, IP addresses play a dual role of locators and identifiers. This is bad engineering and leads to the current situation. The Host Identity Protocol (HIP) has been in use by boeing and the US army for years now. The revised version (HIPv2) hasn't seen an open-source implementation yet. If someone with enough time and skill wants to change the world, a good implementation of HIPv2 will have a very positive impact. https://tools.ietf.org/html/rfc7401 https://tools.ietf.org/html/rfc7401
