This month our team has continued to see great progress on our major focus at the moment, the Pollen testnet implementation of IOTA 2.0. We are pushing hard to implement the final remaining elements of the specification in what will ultimately be our next major milestone in the delivery of IOTA 2.0: Nectar.

This first full implementation of Nectar, expected sometime in Q1, is a major release from our perspective, because it represents, in essence, our first successful delivery of the theoretical concepts of our Coordicide solution.

For those who have been following along these many months of Coordicide development…


This month our researchers have been hitting their stride on various projects. Good progress continues to be made on our Pollen testnet. We are especially grateful for the community participation in testing at this stage. We are encouraged by the level of interest. Elsewhere, we continue our regular engagement with our several grantees, who are doing fabulous work.

Meanwhile, some of our teams continue proving all the Coordicide components through our internal validation tests. It is exciting to watch all these moving parts in motion, as we move towards the launch of IOTA 2.0. …


We are happy to share the following updates from several of our groups. It has been a busy month for everyone on the team. In addition to the work described below, we’ve also been busy planning our next ReSum meeting, to be held later this month.

We invite all the community to join the AMA with the IF Team happening next Wednesday (October 14th) at 1PM CEST | 7AM EST on Reddit. We will be answering your questions about Coordicide.

Without further ado, here are the updates!

Pollen Testnet Implementation. This month the team has been focused on cleaning up…


With the easing of travel restrictions in Europe, our department was able to have its first summit since February. The primary purpose of this meeting was to review all the specifications which each group had been working on over the last few weeks. With our theoretical Coordicide research nearing its end, our research is moving into a new phase, where we are focused on the following tasks:

  • Tying up the last few loose ends in the specifications and completing specifications documents
  • Implementing the specifications into the next version of our testnet, Nectar
  • Sharding research

With our research moving into this…


The past month has been very productive for our team, as we move toward a full, formal specification of IOTA 2.0. Our team has been hard at work across the board, both on wrapping up current tasks, as well as beginning to plan for our post-specification research. Below are the updates from several of our research groups. Please note that we’re planning to reformulate a few of the groups that have already concluded specification work, so next month’s update will have a slightly different presentation.

GoShimmer Implementation. This month the GoShimmer team has focused on making the Pollen testnet more…


This month, we were honored to release Pollen, the first testnet version of IOTA 2.0 to include Fast Probabilistic Consensus, the consensus mechanism for the post-Coordicide IOTA. Work continues on the finalization and further integration of our research specifications into future updates, with a major milestone this month being the finalized version of two types of mana implementations.

Below are the updates from several of our research groups.

GoShimmer Implementation. Last week, we released Pollen, our first fully decentralized testnet based on GoShimmer v0.2.0. Pollen represents a major upgrade with respect to the previous Alphanet v0.1.3 release. We count roughly…


We have a few exciting status updates to share with everyone this month: First, the new GoShimmer release v0.2.0 is planned for the end of June. We consider this release to be a significant milestone, as it will support value transactions and conflict resolution via FPC for the first time. It will also include updates such as a different transaction layout, UTXO, support for “parallel-reality” ledger states, binary (encoding, cryptographic signatures and hash functions), new APIs and more. …


The past month has been incredibly productive for us as we tie up the last few details around the Coordicide specifications. Handing over the Coordicide specifications to development will be a major milestone for our team. We appreciate everyone’s interest in our work and patience throughout this process. Below are specific updates highlighting progress in each area.

GoShimmer Implementation. The GoShimmer team has been focused on the integration of FPC with the value Tangle. A major effort has been dedicated to refactoring the entire value transaction process so as to make the code more stable and clean. We have also…


We’re pleased to share the latest news from the IOTA Research department. We hope that you enjoyed the Introduction to Coordicide Specifications presentations we released recently. Below are the latest updates on our progress.

“Naming” meeting. Several researchers met with additional members of the Foundation to name many of the new Coordicide structures. This may seem trivial, but it is actually difficult due to their importance and permanence. Both internal and external developers need to understand how IOTA works in order to build applications. …


IOTA Research Status Update

March 2020

Our research groups are pleased to share our latest progress updates from February & March 2020. All groups are progressing nicely toward our goals. Much progress has been made since our February ReSum — where we were engaged with the topics outlined below, as well as liaising with several of our engineers, with whom we are working together to translate our results into end-user products

Research Meeting — Lisbon Summit: This Research Meeting had a different approach than previous meetings. With most Cordicide questions answered and a large number of its components well specified…
