Tutorial: Building a Browser Extension With Irmin
Irmin is a collection of OCaml libraries that makes it easy to build applications with Git-like data stores. We recently released irmin-client and irmin-server as official Irmin packages. These packages open up a new way to use Irmin by implementing a custom protocol that lets you write a client app…
Optimising Archive Node Storage for Tezos
For the past few years, Tarides has been responsible for the storage component of Tezos, from L1 and L2 shells up to the Tezos protocol. In 2022, our main focus was on improving storage performance and UX for running nodes and bakers. Our efforts resulted in significant improvements, including reduc…

Towards Minimal Disk-Usage for Tezos Bakers
Over the last few months, Tarides has focused on designing, prototyping, and integrating a new feature for Tezos bakers: automatic context pruning for rolling and full nodes. This feature will allow bakers to run Tezos with minimal disk usage while continuing to enjoy 12x more responsive operations.…
Irmin in the Browser
Introduction Over the past six months, I have been working on using Irmin in the browser, including irmin-server and the GraphQL interface. This has been fun and a great learning journey for me. Before this internship, irmin-server was primarily a Unix-based application. My project was to port irmin…

Adding Merkle Proofs to Tezos
The Upcoming Tezos Jakarta Protocol will support compact Merkle proofs to scale the network's trust infrastructure. This allows nodes that do not trust each other to agree on the validity of Tezos transactions with orders of magnitude smaller storage requirements. For instance, the block 2,400,319, …
Lightning Fast with Irmin: Tezos Storage is 6x faster with 1000 TPS surpassed
Over the last year, the Tarides storage team has been focused on scaling the storage layer of Octez, the most popular node implementation for the Tezos blockchain. With the upcoming release of Octez v13, we are reaching our performance goal of supporting one thousand transactions per second (TPS) in…
The New Replaying Benchmark in Irmin
As mentioned in our Tezos Storage / Irmin Summer 2021 Update on the Tezos Agora forum, the Irmin team's goal has been to improve Irmin's performance in order to speed up the Baking Account migration process in Octez, and we managed to make it 10x faster in the first quarter of 2021. Since then, we'v…

Irmin: September 2020 update
This post will survey the latest design decisions and performance improvements made to irmin-pack, the Irmin storage backend used by Tezos. Tezos is an open-source blockchain technology, written in OCaml, which uses many libraries from the MirageOS ecosystem. For more context on the design of irmin-…
Introducing irmin-pack
irmin-pack is an Irmin storage backend that we developed over the last year specifically to meet the Tezos use-case. Tezos nodes were initially using an LMDB-based backend for their storage, which after only a year of activity led to 250 GB disk space usage, with a monthly growth of 25 GB. Our goal …
