The present disclosure generally discloses an Internet security mechanism configured to provide security for Internet resources of the Internet using an Internet blockchain. The Internet blockchain may be configured to provide security for Internet resources of the Internet by supporting various types of verification related to Internet resources of the Internet, which may include verification of Internet resource ownership, verification of Internet resource transactions, and so forth. The Internet blockchain may be configured to enable Internet participants (e.g., Internet registries, Domain Name Service (DNS) entities, Autonomous Systems (ASes), or the like) to verify Internet resource ownership of Internet resources (e.g., Internet Protocol (IP) addresses, AS numbers, IP prefixes, DNS domain names, or the like) by Internet participants, to verify Internet resource transactions (e.g., allocation of IP addresses, allocation of AS numbers, advertisements of IP prefixes, allocation of DNS domain names, or the like) attempted by Internet participants, and so forth.
