Updated Genesis Block – Looking for Technical Feedback

[Francesco Ferraro]

Hello everyone,

Thank you again for all the feedback from my previous post.

I updated several parts of my experimental Python blockchain project before continuing.

Changes made:

- Increased the address length.
- Address separators (-) are now only for display in the wallet.
- Previous block hash is now stored as a full 64-character hash.
- UTXO structure has been updated.
- Added block_height metadata to UTXOs.
- Added spent status handling for UTXOs.
- Mined a new Genesis block after these changes.

Mining result:

Difficulty : 5
Hashrate   : ~241 H/s (Android / Termux)
Nonce      : 307744

Updated Genesis Block:

I'd really appreciate any feedback on the updated Genesis block structure.

Are there any obvious design mistakes or improvements you would recommend before I continue with transaction validation, networking, and mining optimization?

Thank you for taking the time to review it.

I read your updated genesis block post. Since the genesis identity, initial parameters and launch assumptions may become the reference point for every future release, do you plan to maintain a permanent public history of all consensus decisions, corrections and launch commitments?

Git can preserve source changes, but explanations, announcements and roadmap statements can still be edited or disappear. How will a future node operator verify exactly what the project originally stated at launch?

Thanks! I appreciate your feedback.

I'm building this project step by step and learning as I go. I'll keep posting updates here whenever I complete a milestone or improve something.
