Hi folks,

Yesterday we launched our second test network for Simplicity on Elements.
You can find details on the software and configuration on the wiki at <
https://github.com/BlockstreamResearch/simplicity/wiki/Test-Network>.

In addition to several new jets for basic arithmetic operations such as
division, min, max, etc, the specification of jets have been amended to
additionally include a commitment to their assigned costs (in milliWU).
This change has affected the hash of every jet, and therefore adjusted the
address of any scriptpubkey that uses jets.  For this reason it was
necessary to start a new test network.

Users can participate on the test network by building the
simplicityregtest1 tagged version of Elements found at <
https://github.com/ElementsProject/elements/releases/tag/simplicityregtest1-0.0>
or by grabbing a binary from <
https://github.com/psgreco/elements/releases/tag/simplicityregtest1-0.0>.
In either case you will need to setup your elements.conf file as indicated
on the wiki at <
https://github.com/BlockstreamResearch/simplicity/wiki/Test-Network>.

The Elements client only provides the consensus rules for dealing with
Simplicity transactions.  You will need a separate program to help create
Simplicity transactions.  Tooling for that is under development at <
https://github.com/BlockstreamResearch/rust-simplicity> and we hope to say
more about that soon.

You can also find a short tutorial on using the Haskell reference
implementation to create and send a simple Simplicity transaction at <
https://asciinema.org/a/598240>.  Be aware that this video describes using
the previous test network.  I will upload a new video for the new test
network soon, but you should find that the process overall is basically the
same.
