Overview
Vcoincheck is a Vietnamese-language video archive that teaches blockchain basics without asking anyone to learn them in English. Its recordings walk through setting up a crypto wallet, voting on community funding proposals, and writing simple financial agreements in code1. Publishing stopped in July 2025, which leaves a fixed library rather than a running series2.
The channel is the video arm of Viet Cardano Community, a group that has run Cardano meetups, a Vietnamese discussion forum and a written knowledge library since the network's early years in the country3. Much of the material was paid for through Project Catalyst, the fund that Cardano holders vote on to finance community work. Five of the group's proposals were funded and delivered4. The written half of that work, explainers covering the same ground in English and Vietnamese, is still readable on the group's own site5.
Key Features
- Full training courses on Marlowe, taught in Vietnamese. Two multi-session courses and a numbered workshop series work through Marlowe, a tool for writing financial agreements that run on Cardano without deep programming experience2.
- Screen-shared wallet walkthroughs. Tutorials record the real clicks for Daedalus, Yoroi, Eternl, Nami and Lace, the apps people use to hold and spend ADA, so a first-timer can follow along in their own language1.
- A plain-language series on how the network agrees on anything. Seven episodes cover Ouroboros, the rulebook that decides who writes the next block: five work through named variants (Classic and BFT, Praos, Genesis and Crypsinous, Chronos, Leios) and two give the overview. The same ground is covered in writing on the team's knowledge site for anyone who would rather read5.
- Snapshots of the first wave of Cardano DeFi. The earliest videos assess trading and lending apps as they were launching, which makes them a record of what that corner of the ecosystem looked like before those projects matured.
- Course code anyone can open. The team's public repositories hold the notebooks and sample contracts used in the Marlowe sessions, so a viewer can work from the same files as the instructor6.
What to Expect
Everything is spoken in Vietnamese and most titles follow. Someone without the language can still follow the screen shares, and automatic captions cover the rest roughly. Sessions run long: the Marlowe material is recorded as full classes rather than edited explainers, closer to sitting in on a lesson than watching a tutorial2.
The scale is modest and the production is plain: a host talking over a shared screen, no studio. These were made for a training cohort rather than for browsing, so the pace assumes you are following along.
Anything about the state of the ecosystem will have aged; the wallet and Marlowe walkthroughs hold up better, since the underlying tools change slowly. The team behind it has not gone quiet even though the channel has. It organises meetups in Hanoi and Ho Chi Minh City7, has published code to public repositories6, and runs a Vietnamese Telegram group as its day-to-day room8. For coverage in other languages, the directory's YouTube channel listings are the place to look.
