First Open-Source Release of TzScan
In October 2017, after the Tezos ICO, OCamlPro started to work on a block explorer for Tezos. For us, it was the most important software that we could contribute to the community, after the node itself, of course. We used it internally to monitor the Tezos alphanet, until its official public release in February 2018, as TzScan. One of TzScan main goals was to make the complex DPOS consensus algorithm of Tezos easier to understand, to follow, especially for bakers who will contribute to it. Since its creation, we have been improving it every day, rushing for the Betanet in June 2018, and still now, monitoring all the Tezos networks, Mainnet, Alphanet and Zeronet.
So we are pleased today to announce the first release of TzScan OS, the open-source version of TzScan!
The sources are available on Gitlab: https://gitlab.com/tzscan/tzscan
The code, mostly OCaml, is distributed under GNU GPL v3.
The project contains:
The blockchain crawler, used to monitor the blockchain, and fill a PostgreSQL database
The web interface, requesting information using a REST API
The API server, using the PostgreSQL database to reply to API requests
It can be used in two different modes:
Remote Use: if you are not running a Tezos node, you might want to only run the web interface, using the official TzScan API server
Local Use: if you are running a Tezos node, you can use the crawler and the API server to serve information on your node, to a locally running web interface
If you are interested in contributing to TzScan OS, a first step could be to translate TzScan in your language : check the file lang-en.json for a list of strings to translate, and lang-fr.json for a partial translation!
OCamlPro’s services around TzScan
TzScan OS can be used to monitor private/enterprise deployments of Tezos. OCamlPro is available to help and support such deployments.
We are thankful to the Tezos Foundation and Ryan Jesperson for their support!
All feedback is welcome!
OCamlPro is a R&D lab founded in 2011, with the mission to help industrial users benefit from state-of-the art programming languages like OCaml and Rust.
We design, create and implement custom ad-hoc software for our clients. We also have a long experience in developing and maintaining open-source tooling for OCaml, such as Opam, TryOCaml, ocp-indent, ocp-index and ocp-browser, and we contribute to the core-development of OCaml, notably with our work on the Flambda optimizer branch.
Another area of expertise is that of Formal Methods, with tools such as our SMT Solver Alt-Ergo (check our Alt-Ergo Users'). We also provide vocational trainings in OCaml and Rust, and we can build courses on formal methods on-demand. Do not hesitate to reach out by email: email@example.com.
