VoiceChain Sync

Securely synchronize and timestamp voice acting tracks with animation frames on blockchain.

The primitive.

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

Why this primitiveHedera testnet contracts ensure immutable matching records of audio and frame data.
