The past weeks our engineering department has been transitioning to a very different, and much more open communication model with our community. Regular updates for Trinity, Entangled, IRI and client libraries are now coming out.

Probably even more visible, at least if you are active on our Discord, is the presence of new channels. The day-to-day development team discussions are now happening in these channels. The channels are visible to anyone. For IRI and client libraries, the channels are:

Client libraries

In the previous update we mentioned that the client libraries team has been mainly working on a design of functionality the libraries will support in the full 1.0.0 release. The main part of that is about making libraries stateful. Last week, we officially started the development of the first version of what we call the Account module.

If you are a developer, you can look at the spec in Go, here. We’re aiming for having a first version of the account module usable in a new beta release of the client libraries within February. The design and implementation will then iteratively evolve towards the full 1.0.0 release.


The main focus of the past couple weeks has been and still is investigating and fixing issues with IRI 1.6.0. Some of the issues relate to syncing, others to high resource consumption in certain scenarios. We’re still heads down debugging and fixing the issues, but we’ve already made some fixes that will be present in IRI 1.6.1.

PRs merged since the last release:

- Add configurable variables for spent addresses DB#1274
- Fix: added a buffer to LSManager #1286
- Fix: test existence of spent addresses db do not point to correct folder #1305
- Fix: Batch process spent addresses to avoid out of memory issues #1314
- Fresh transactionToRequest #1316
- Fix for (closed) issue #1086, missing user-agent header in cors #1319
