This work is both beautiful and important. Bitcoin-Certified Addresses (BCA) is superior to Cryptographically Generated Addresses (CGA) by orders of magnitude measured by computational time and costs. This is not Bitcoin coming to IPv6's surprise with a self-recommendation of new things to do (although that certainly has its long-term future), but Bitcoin coming to IPv6's own problem with a solution that is a million times more efficient and cost-effective to an existing problem. This may become a critical component of the future Internet integrating blockchain and IPv6. The future of IoT will depend on it. A host can register its public key on the Bitcoin blockchain by generating a Bitcoin transaction. The binding between the blockchain-registered public key and the Bitcoin addresses is secured by the search performed by Bitcoin nodes for a valid block header, rather than the search by the host for a valid modifier in CGA. This substitution has profound implications. It pitches illegal attackers against the powerful law-obeying Bitcoin nodes, not the individual hosts (users) with CGA. It is game changing. In addition to the direct practical applications, it also elucidates certain POVs in the philosophy of Bitcoin: (1) It is another excellent example proving that PoW is superior to other consensuses. PoW is already proven superior even when the puzzle-solving work has no utility other than PoW itself. But now, even the work previously considered wasteful has an excellent utility case. (2) It illustrates, by analogy, the superiority of the SWN of the miners to the mesh network of nonmining users. BCA proves that professionalized PoW SWN, with its open economic competition and transparency, trumps the amateur 'proof of existence' hobbyist network. With BCA, the IPv6-based New Internet will have its ultimate protective armor, efficient and powerful enough to defeat even the most organized attackers. It gains superiority not by the sheer power of technology as a commodity (which is neutral), but by economics, which is inherently asymmetric between illegal attackers and law-obeying nodes due to the nature of PoW.
