Overview
Viper Science YouTube is a channel where a two-person engineering firm records short talks about the open-source developer tools it builds. A few videos are wrap-up summaries posted when a funded project finishes; most of the channel is earlier material — walkthroughs on setting up and running a blockchain server, delegation analyses, and videos about an NFT project the team ran. The engineers appear by name, and the code behind the work is public.
The firm is Viper Science, LLC, a United States company run by Dylan Crocker and Willie Marchetto, both of whom publish their names, degrees, and direct email addresses on the company site1. Their work is Cardano tooling: a C++ software development kit called libcardano, a Python library called Cardano-Tools, client libraries for talking to a Cardano node, and the VIPER stake pool itself2. Several of the team's proposals to Project Catalyst, Cardano's community funding program, have been funded, and some of that work is summarized in the videos once it is finished.
Key Features
- A build log rather than a course. Several videos mark a finished piece of work (a library released, a funding milestone closed) rather than teaching a subject from the beginning3.
- The people behind the code are named. Both founders publish photographs, degrees, and contact addresses, and both have run Cardano stake pools since 20191.
- The tools discussed are open to inspect. The projects covered in the videos sit in a public code group, and the C++ toolkit ships generated reference documentation anyone can read45.
- Short, single-topic talks. A typical upload runs a few minutes: one founder on camera, sometimes a screen share, no intro sequence.
- An early guide to running a node. Two videos walk through building and deploying a Cardano node inside a Docker container, which is the first step in running a stake pool. They were recorded in November 2020, against a node release many major versions old3.
What to Expect
Expect something plain and small. A video is usually a founder explaining what a project set out to do and what actually shipped, in the language an engineer would use with a colleague. There is no host, no editing flourish, and no price or trading content anywhere on the channel.
Uploads arrive when a project closes out rather than on a schedule, so the channel reads as a record of completed work. Long stretches pass between videos. The team's day-to-day activity is easier to follow through its public code group, where the libraries were still receiving commits in July 2026, and through the company site that lists what each project does42.
Anyone wanting a structured introduction to writing Cardano software or operating a node will get further with a learning platform or a development guide. What Viper Science YouTube adds is the other half of the picture: a small funded team saying, in its own words, what it built and why.
