Establishing an immutable on-chain record of your creative process requires coordinating three systems: your project management tool for timestamped decision trails, your version control for file history, and the blockchain for permanent anchoring. The workflow begins by treating JIRA as your authoritative log of creative intent—every design decision, revision request, and approval gets captured as a ticket with timestamps that prove when ideas originated. GitHub then serves as your evidence repository, where you commit not just final assets but work-in-progress files, sketches, and iteration notes, with each commit hash representing a cryptographic fingerprint of your files at that moment in time. Finally, you periodically anchor this evidence to Ethereum by publishing a hash of your GitHub repository state (or specific commit hashes) to a smart contract, creating a tamper-proof timestamp that proves your files existed in that exact form at that block's timestamp.
JIRA Configuration: Create a dedicated project with custom fields for "Creative Stage" (concept, draft, revision, final) and "Evidence Links" for attaching reference screenshots. Enable full audit logging and configure automation rules to capture state transitions. Export periodic CSV backups of your issue history.
GitHub Workflow: Use a dedicated repository with a clear folder structure separating concepts, iterations, and finals. Commit early and often with descriptive messages referencing JIRA ticket numbers. Tag significant milestones and use signed commits for additional authenticity. Generate SHA-256 hashes of critical files and include them in commit messages.
Ethereum Anchoring: Deploy a simple registry contract or use an existing timestamping service like OpenTimestamps or OriginStamp. At key milestones, compute a Merkle root of your evidence (combining JIRA export hashes and Git commit hashes) and submit it as a transaction. Store the transaction hash and block number in your project documentation as your proof of existence timestamp.
