The New dHealth Protocol Paper

We’re releasing Version 0.1 of the new dHealth Protocol Paper. It is a reset of dHealth’s architecture, economics, and long-term direction. This isn’t a minor upgrade. It’s a restart designed for continuous care, AI, and care robots.

We’re moving from Cøsmos to Solana

We are moving from the Cøsmos app chain to Solana because maintaining a standalone chain diverts resources from healthcare adoption and introduces growing operational complexity and ecosystem uncertainty. Solana provides a production-grade, high-throughput execution layer that supports the high-frequency, low-latency attestations required for continuous care, AI systems, and care robots. This shift allows dHealth to focus entirely on verifiable healthcare use cases while anchoring governance and inflation on a single, robust canonical chain.

From PDFs to verifiable proof

Healthcare still relies on portals, PDFs, and vendor logs that are hard to verify across organisations. dHealth replaces that with proof of action built on four primitives:

• Credentials (who)

• Schemas (meaning)

• Attestations (what happened)

• Mandates (under what authority)

No raw health data goes on-chain - only cryptographic proofs and references.

The key design shift: meaning vs. money

The protocol separates accountability from payments:

• Stablecoins for reimbursements and payments

• DHP for identity, mandates, attestations, and governance

DHP isn’t “money.” It’s the asset that makes actions accountable.

DHP becomes collateral (this drives demand)

Participation requires locking DHP (reclaimable after the lock period):

• Individuals: USD 15 worth of DHP

• AI/robots: USD 10 worth of DHP

• Organisations: USD 500 worth of DHP

Crucially, this is acquire-and-lock, not spend. As more providers, insurers, research organisations, and care networks onboard users and issue attestations, they must acquire and lock in more DHP, reducing circulating supply and creating structural demand.

2% inflation, only for real contributors

Solana-native DHP has 2% annual inflation, emitted quarterly. Passive holding earns nothing. Rewards go to active participants, i.e. individuals/machines for verified activity, and organisations for attestations and onboarding.

Built for AI and care robots—human-first

AI agents and robots are first-class identities, but they act only under explicit, revocable mandates, keeping responsibility traceable to humans.

One canonical chain

Solana is the single source of truth for governance and inflation; wrapped tokens elsewhere don’t govern or inflate.

The bottom line

This restart shifts dHealth from “running a chain” to enabling verifiable healthcare at scale:

• proof instead of PDFs

• Authority instead of implicit trust

• stable payments instead of token-as-money

• DHP as collateral that scales with adoption

That’s why the migration matters and why DHP demand becomes real and persistent.
