No crypto knowledge required. Just clear, useful tools that happen to run on a blockchain.

  • Upload photos and short videos as stories
  • Automatic fade after 24 hours from the public view

Steem Quantum Vault interface preview
Technology Demo — Concept Published

Steem Quantum Vault

Preparing Steem for the post-quantum era.

  • Witness multi-signature bridge custody
  • Reconciliation dashboard for transparency
  • AI-based protocol-level anomaly detection

Steem API Monitor interface preview
In Development — Q2 2026

Steem API Monitor

Transparency for the network that powers Steem.

Steem runs on a handful of public API servers. When they fail, frontends break. The Monitor continuously tests every known node and publishes transparent daily reports — uptime, latency by region, outage logs.

  • Continuous monitoring of all public Steem API nodes
  • Regional latency heatmap
  • Daily reports published on the Steem blockchain
  • Live dashboard with historical data
  • Open source measurement methodology
  • Drop-in client-side switcher for frontends
03 — About

Infrastructure, tools, and ideas — built in the open.

The Author

Holger Jacob
@greece-lover · Steem Witness

All projects on this site are developed by Holger Jacob, a Steem witness and long-time contributor to decentralized community platforms. Before joining Steem, he built and grew a German-speaking online community of over 600,000 members — experience that shapes how these projects are designed today.

The focus of his work on Steem is practical: building things that solve real problems for real users, publishing the methodology openly, and making the Steem ecosystem more reliable and more accessible — one project at a time.

Every project listed here is live, in public development, or transparently labeled as a concept. When something is still being built, the card says so honestly.

04 — Support the Work

If the work matters to you, vote.

The most meaningful way to support ongoing development is a witness vote for @greece-lover. Witness income funds infrastructure, tools, and time for new projects. No donations, no proposals — just your vote, if you think the work deserves it.
