NEM Foundation Technology Department Update - October 2019

Summary

September Tech Update

  • Core devs released a new version of Catapult, codenamed Fushicho. The update comes with basic DoS protection to ban nodes and close connections of nodes with bad behaviour and several bugfixes and standardization changes.

  • NEM Foundation Testnet for Catapult will soon be running Fushicho protocol version. We are currently inspecting the Fushicho feature set and will update our network accordingly.

  • The NEM Developer Center is constantly being updated to integrate latest Catapult features. Find out what has been worked on by our Technical Writers.

  • A new version of the Command Line Interface for Catapult is now available (nem2-cliv0.13.2) with some features add ons to work with address and mosaic restrictions.

  • The Block/Network Explorer (Super Explorer Framework) project has seen many contributions over the course of September.

  • The Desktop Wallet project has also seen many contributions and the team is currently working on Fushicho compatibility to match our Testnet as soon as it is upgraded.

  • The Mobile Wallet project is moving along with new features.

  • The technology department of the NEM Foundation has helped with contributions to the migration committee in order to provide an optin migration action plan.

Protocol Updates

The Catapult Fushicho release introduces basic DoS (Denial of Service) protection and several bug fixes/changes to the protocol.

This latest release adds support for latest compiler versions (CLANG9 and GCC9) as well as upgrades all dependencies of the protocol software. It also introduces a few more standardization changes recommended by the standardization working group around MongoDB collections and configuration changes.

Several fixes have been added as well, including one for a bug in the processing of delegated harvester unlocking messages and another that notifies potential cosignatories once they are added to a multisig.

Adding to these, the protocol now identifies servers by resolved IP instead of only by their public keys, this change requires that every node public key is mapped to a single host at one time. There is also a new monitoring of static nodes that will track any IP change of those servers.

Participate in our #general discussions, we are happy for any feedback!

NEM Foundation Experimental Testnet

NEM Foundation Testnet for Catapult is now running Fushicho milestone. The currently available test network is still experimental and reseted everytime there is a new milestone release.

In parallel to the Testnet, NEM Foundation members have been working on beta version of client applications that can be used on the test network, as found in the following list:

We are glad to announce a period of open beta testing for these software packages. Source code reviews can happen at Github as these projects are all open source.

Participate in our #testnet discussions, we are happy for any feedback!

NEM Developer Center

The NEM Developer Center is the place to learn about Catapult features. NEM Foundation Technology Department members are working on the documentation and technical guides for Catapult on a daily basis.

Guides and documentation that has been added over the course of September include, but are not limited to:

Command Line Interface & Software Development Kits

A new version of the Command Line Interface for Catapult is now available (nem2-cliv0.13.2) with some features add ons to retrieve restrictions and metadata, this package is still running Elephant 3 compatibility.

Also, the guys over at NEM Studios have been doing sprints to catch up with latest Catapult Fushicho release. In fact, a new version of the TypeScript SDK v0.14.0 is available at Github which brings features like address restrictions, mosaic restrictions and metadata.

These projects and their source code are managed under the NEMTech Community Project Management Committee.
