By OCamlPro & Origin Labs Writing smart contacts may often be a burdensome task, as you need to learn a new language for each blockchain you target. In the Dune Network team, we are willing to provide as many possibilities as possible for developers to thrive in an accessible and secure framework. T... (Read more)

2019 at OCamlPro OCamlPro was created to help OCaml and formal methods spread into the industry. We grew from 1 to 21 engineers, still strongly sharing this ambitious goal! The year 2019 at OCamlPro was very lively, with fantastic accomplishments all along! Let's quickly review the past years' works... (Read more)

OCamlPro started working on blockchains in 2014, when Arthur Breitman came to us with an initial idea to develop the Tezos ledger. The idea was very challenging with a lot of innovations. So, we collaborated with him to write a specification, and to turn the specification into OCaml code. Since then... (Read more)

This article is the third post of a series of posts on improving Tezos storage. In our previous post, we announced the availability of a docker image for beta testers, wanting to test our storage and garbage collector. Today, we are glad to announce that we rebased our code on the latest version of ... (Read more)

In a previous post, we presented some work that we did to improve the quantity of storage used by the Tezos node. Our post generated a lot of comments, in which upcoming features such as garbage collection and pruning were introduced. It also motivated us to keep working on this (hot) topic, and we ...

A reflection on the new year… Today, Tezos is a global network and an open source project with developers spanning over five continents. In the inception of this project, the French company OCamlPro which, to this day, stills develops numerous projects around Tezos, played a particularly important... (Read more)

Running a Tezos node currently costs a lot of disk space, about 59 GB for the context database, the place where the node stores the states corresponding to every block in the blockchain, since the first one. Of course, this is going to decrease once garbage collection is integrated, i.e. removing ve... (Read more)

In a previous blogpost, we presented the RPCs used by tezos-client to send a transfer operation to a tezos-node. We were left with two remaining questions: How to forge a binary operation, for signature How to sign a binary operation In this post, we will reply to these questions. We are still assum...

In this technical blog post, we will briefly introduce Tezos RPCs through a simple example: we will show how the tezos-client program interacts with the tezos-node during a transfer command. Tezos RPCs are HTTP queries (GET or POST) to which tezos-node replies in JSON format. They are the only way f... (Read more)

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... (Read more)
