So, we collaborated with him to write a specification, and to turn the specification into OCaml code. Since then... (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 ...

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)
