Thorkil Værge
- Last Week: Concentrated on VXB wallet development and Neptune Core integration. Successfully modified Neptune Core for VXB compatibility and achieved a functional state for the wallet. Began addressing critical security issues identified in a recent report.
- Coming Week: Will continue working through back-end security fixes in Rust. Plans to merge high-quality contributions from 21 Cipher into Neptune Core. Will also initiate discussions with an external developer regarding necessary endpoints for a new mobile wallet.
3. Technical Discussion
Block Header & Hard Fork Preparation
The team has reached a round point in the block header data structure. The integration was smoother than expected, providing a solid foundation for the upcoming hard fork beta. A formal review is the next step.
VXB Wallet Security and Architecture
The VXB wallet is now operational, but the priority has shifted to hardening. The team is currently addressing “critical” flagged items from a security audit.
Architecturally, the “wallet server” was clarified to be a version of Neptune Core acting as a peer to other nodes while serving the wallet client. The team is also evaluating the privacy implications of a new “nimble” mobile wallet. While the VXB wallet is designed to leak zero privacy (equivalent to a full node issuing a transaction), the mobile version may require a different balance of data efficiency versus privacy, which will be the subject of upcoming technical design talks.
4. Updates and Announcements
- VXB Wallet: The wallet is now functional, with security hardening currently underway.
- Neptune Core: Integration of community contributions is expected to be merged early this week.
- Mobile Development: Initial discovery has begun for a lightweight mobile wallet client.
