The last few days have been thrilling for the Lisk community, as the Lisk Team announced in a blog post the release of Core 2.0.0 on Mainnet and the publication of the SDK 2.0.0 on the NPM registry. In this article we summarize the most important updates.

The importance of the moment was also strongly underlined in a tweet by President and CEO Max Kordek.

I worked my ass off for over three years to achieve tomorrow! So excited to see the Lisk SDK finally becoming a reality. ? This is just the beginning for Lisk. ? — Max Kordek (@MaxKordek) July 23, 2019



Lisk Core 2.0.0 is the first Core release developed by means of the Lisk SDK. For this reason, the SDK 2.0.0 has also been published on the NPM, which is the Javascript Package Registry. Basically it is the first version of the Lisk SDK without the support for custom transactions, which, on the contrary, have been implemented in the 2.1.0 version of the SDK (as we mentioned in the article regarding the June Development Update). Furthermore, from this point forward, Core and SDK will be released at different times, allowing a faster implementation of developers’ feedbacks.

The release has been followed up by the completion of several roadmap objectives, such as the implementation of design pattern for protocol change, creations of transactions element and transaction pool element.

Coming back down to Lisk Core 2.0.0, we point out that this release will introduce a soft fork, that will be activated automatically at block height 10,000,000. As it was already announced, the time between the release and the actual soft fork has been extended from 14 days to one month (it will occur on 23rd August), in order to offer all node operators enough time to upgrade their nodes. Until that moment, the team recommends to continue using the previous version, that is Lisk Core 1.6.0.

Lisk Core 2.0.0 also brings some important changes that affects all node operators, in particular about API (such as the removal of unconfirmedBalance property from two API endpoints), soft fork (end of support for type5 dapp registration transactions), and other changes (modifications to logging system and configuration files). Furthermore, the new version of Lisk Core also brings two important improvements. The first is the enhancement of the transaction processing efficiency by the optimization of the transaction verification and database persistence. The second is the new P2P Library that allows more stable connections between peers.

Finally, we point out another important change affecting both Lisk Core 2.0.0 and Lisk SDK 2.0.0: software license GNU GPL v3.0 has been replaced by a more permissive Apache 2.0. The license change from GNU to Apache will make Lisk more attractive to potential developers as there are less “strings attached” when developers incorporate Lisk into their products, as stated by Nimbus.
