Dragonchain

Dragonchain began in 2014 as a private blockchain experiment inside Disney, was open-sourced in 2016, and takes a hybrid public-private route: business data stays on a permissioned chain while transaction proofs climb a ladder and anchor to Bitcoin, Ethereum and other public networks. Its five-level consensus separates business, validation, network diversity, notary and public verification: low-sensitivity workloads stop at the lower rungs to save cost while high-value proofs climb the ladder, so an enterprise can pick proof strength to match its compliance needs without exposing raw data.

Contracts run in Python, Java, Node.js or C#, so conventional engineering teams deploy without learning Solidity. The product line covers the Factor decentralised identity platform, the Lyceum learning-credential system, anti-fraud and compliance attestation, enterprise NFTs, and quantum-safe encryption with Aqed. DRGN is defined as a tokenised micro licence used to pay for platform services and node operation. On the regulatory side, the SEC's 7 April 2026 enforcement review listed Dragonchain among the cases it had dismissed, alongside Coinbase and Kraken.
