Yazan Markabi

The Markabi twins (Zaid & Yazan) began their journey by learning Visual Basic 6 in ninth grade (2006). They created open‑source 3D games using the TrueVision3D library and shared many projects on Planet‑Source‑Code.

They collaborated with José Mota during a period of Syrian economic sanctions, and later with Dr. Neil Henry Halpen, a British‑Dutch physicist. Together, they built a massive 3D educational software suite over four years.

Shifting to web development, they launched the pioneering platform "LikesASAP" in 2011 — the first social media engagement system to pay users in cash and cryptocurrency. After rapid growth, the project was sold to investor Dimitry but later shut down following a Facebook lawsuit and a two‑year ban.

As interest in social media "likes" faded and cryptocurrency rose, the team created several major crypto platforms — most notably DonaldCoin, which paid out over 200 BTC during its peak.

With Bitcoin fees rising dramatically, the team developed ZeroChain: a modified blockchain with zero transaction fees, a decentralized wallet, API integrations, and a peer‑to‑peer token marketplace.
