Onchain Narrative Branches

Record player story choices on Hedera testnet to create transparent, shared branching narratives.

Hedera smart contract (HSCS)· onchain logic

Section · Onchain

The primitive.

Storytelling gets a tiny Solidity contract deployed to Hedera testnet through the JSON-RPC relay; game designers see a 'verified onchain' badge with the live address and a one-tap HashScan link.

Why this primitiveHedera testnet offers immutable audit trails for branching decisions enhancing shared story experiences.
