A portfolio of projects dedicated to making Steem more accessible, more reliable, and more secure — for everyday users, developers, and witnesses.
No crypto knowledge required. Just clear, useful tools that happen to run on a blockchain.
The social platform that feels like home.
A complete social media platform built on the Steem blockchain. Writing, sharing, commenting, connecting — combined with the ownership and permanence that only a blockchain can provide.
A marketplace for self-publishing authors.
Upload your book, set your price, share your link. WelBook handles PDF and EPUB delivery, generates signed download URLs so only paying readers access your work, and provides a free reading sample for every title. Authors keep the revenue — the platform is software, not a middleman.
Stories that disappear — but never get lost.
Share photos and short videos as stories. They fade from the public view after 24 hours, but they stay permanently in your personal archive if you want them to. Classic ephemeral feeds are one-way streets — WelSnap gives you the freedom of a story feed without losing your own memories.
Recipes that travel with you.
A recipe database built for people who actually cook. Save your favorites, discover new ones from the community, organize your ingredients, and plan meals. Your recipes stay yours — exportable, portable, and permanent on the blockchain if you choose.
A puzzle game with a neon heart.
Fast-paced puzzle where strategy meets reflex. Clear blocks, build combos, climb the leaderboard. Scores and achievements live on the blockchain — permanent, portable, verifiable.
Tools, monitoring, and research for developers, witnesses, and anyone who cares about Steem's future.
Never lose your account again.
Browser-based tool guiding you through every step of account recovery — whether you are the trustee monitoring accounts or the victim regaining access. Private keys never leave your browser.
Preparing Steem for the post-quantum era.
Technology demonstration showing how Steem can adapt to post-quantum cryptography — through a mirror-chain architecture that adds Dilithium signatures alongside ECDSA, without a disruptive hard fork.
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.
The Author
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.
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.
