The launch of the first IOTA Coordicide public testnet could be earlier than expected. After the announcement last week that the new version of GoShimmer v.0.2.0 is in its final phase and that the release is scheduled for the end of June, it seems that this version is now advanced. Yesterday, Angelo Capossele, principal researcher at the IOTA Foundation , wrote via Twitter:
For the upcoming #Coordicide testnet, we really want you to see and understand better how our rapid probabilistic consensus protocol works. I hope that with the new integration of #Grafana and #Prometheus we can accomplish this!
In response, Hans Moog, software developer at the IOTA Foundation , announced that the first public coordination testnet will be released in the coming days.
T minus 5 days.
Until now, the Testnet Coordicide was only available as an internal alphanet in version 0.1.x. The version was launched in early February and included basic features such as self-drilling, gossip, rate control and an interface to send 0 value transactions and to query the Tangle. The new version 0.2.0 will be much more complete in its scope and will also include the new consensus model, the “Parallel Reality Based LEDGER State”. In this sense, Moog went on and explained:
It will be the first time that we will have most of the building blocks of the coordicide in a real knot implementation. There will most likely be minor bugs and things that need to be fixed but from that point on we will not only be able to collect the first real live measurements, but we will also be able to have much faster iterations between consecutive versions.
It is therefore a very important milestone on our way to the coordicide and I look forward to presenting many new and exciting concepts and features in the weeks to come.
As Serguei Popov explained in a recent shared status update, GoShimmer v.0.2.0 will support value transactions and dispute resolution on FPC for the first time. In addition to the "Ledger State Based on Parallel Reality", another transaction provision, UTXO, full conversion to binary code and new APIs will be introduced.
As Capossele shows with the screenshot above, the IOTA community will also get to know the rapid probabilistic consensus protocol and its handling of "conflicts". Unlike a blockchain, there can be conflicting transactions in IOTA Tangle (without the coordinator) for a short time. For example, malicious transactions can "survive" for a short time in IOTA Tangle until honest nodes recognize the conflict.
Once such a conflict is detected, the nodes decide which transaction to select. The rapid probabilistic consensus is responsible for this. The dashboard (above) also shows, among other things, these resolved conflicts.
