Handshake

Handshake (HNS) is a decentralised naming protocol designed to be compatible with the existing Domain Name System (DNS). It decentralises the root zone file where top-level domain (TLD) ownership information is stored by using a blockchain-based system. This system allows for a root zone that is uncensorable, permissionless, and free of gatekeepers like ICANN. Handshake aims to replace the Certificate Authority (CA) system with cryptographic validation and management of the root zone by all peers in the network. Handshake provides decentralised ownership and management of TLDs. Users can register and manage TLDs, host websites, or act as registrars without centralised authorities. Ownership is maintained through biennial "heartbeat transactions," eliminating yearly rental fees. The protocol enhances internet security and privacy by using a distributed root of trust.

Handshake is used to decentralise the domain name registration process and the management of digital certificates. It enables the creation of a globally unique namespace without relying on a central authority such as ICANN. Users can register top-level domains (TLDs) directly on the Handshake blockchain using the native HNS token through a Vickrey auction system. This mechanism aims to prevent price sniping and ensures fair market value determination for domain names. Handshake’s decentralised infrastructure supports provable data sets and leverages a proof-of-work consensus model to maintain security and integrity across the network. Additionally, Handshake Coin (HNS) is the native currency of the protocol, facilitating the transfer, registration, and update of internet names. This currency aims to counter spam, preventing uncontrolled mass registration of names.
