Input Output Hong Kong (IOHK), an engineering company that is behind the development of Cardano (ADA), headed by Charles Hoskinson, recently made a quick update regarding the progress of Shelley Incentivized Testnet (ITN).

There, it implored the stake pool operators to upgrade to the newest version of Jormungandr that was released a few days ago.

IOHK shared this update via its Twitter handle a couple of hours ago. Going by the report, Jormungandr version 0.8.18 passed quality assurance testing before its release.

The engineering company behind the development of Cardano (ADA) stated that the new version was deployed on ITN as soon as the testing was accomplished.

“A quick ITN update for you after the Easter weekend: a new version of Jormungandr was released late last week. It passed QA testing and is deployed on ITN as of 04/13. This includes a fix for an issue that involved nodes considering a block sent in the future as a valid block.”

“The valid block issue was raised in March, more details are available on Github under #1942 – Node created a strange block on slot 97.060 on March 19. Stake pool operators are recommended to upgrade to this version.”

A Quick Insight into Jormungandr and Node

Jormungandr is a node implementation written in rust, with the aim of supporting the Ouroboros type of consensus protocol.

While a node is a participant of a blockchain network that continuously makes, sends, receives, and validates blocks. Each node is in place to make sure that all the rules constituting the protocol are duly followed.
