Monero (XMR) is a Proof-of-Work blockchain where transaction privacy is enforced by default at the protocol level, meaning ledger data is validated without being publicly readable. Instead of exposing addresses or amounts, Monero relies on cryptographic structures that allow verification while limiting on-chain transparency.

Handshake (HNS) is a Proof-of-Work blockchain that secures a decentralized naming layer for the internet by placing top-level domain ownership directly on-chain. Instead of relying on centralized DNS authorities, Handshake records and verifies domain roots through blockchain consensus, creating a more resilient and permissionless naming infrastructure.

Eaglesong (CKB) secures the Proof-of-Work base layer of the Nervos Network, separating value storage from application logic while enabling interoperable development and long-term network stability through Eaglesong hashing.

Zcash runs on a zero-knowledge Proof-of-Work blockchain that verifies transactions on-chain while keeping data private, using cryptographic validation instead of public transaction transparency.
